- W1000248025 abstract "This volume explores from multiple perspectives the subtle and interesting relationship between the theory of rational choice and Darwinian evolution. In rational choice theory, agents are assumed to make choices that maximize their utility; in evolution, natural selection 'chooses' between phenotypes according to the criterion of fitness maximization. So there is a parallel between utility in rational choice theory and fitness in Darwinian theory. This conceptual link between fitness and utility is mirrored by the interesting parallels between formal models of evolution and rational choice. The essays in this volume, by leading philosophers, economists, biologists and psychologists, explore the connection between evolution and rational choice in a number of different contexts, including choice under uncertainty, strategic decision making and pro-social behaviour. They will be of interest to students and researchers in philosophy of science, evolutionary biology, economics and psychology." @default.

- W1000248387 abstract "Publisher Summary This chapter focuses on the receptors represented in the mesencephalic nucleus that respond to a force applied to the mandibular canine tooth of the cat have been located in the periodontal ligament. They were situated in the intermediate area of the ligament between the fulcrum and the apex of the tooth. The receptors appeared to be unevenly distributed around the tooth root. The area of predominant distribution extended from the labial to the mesial aspect of the ligament. The receptors may be situated in any of the tissues that comprise the periodontium—that is, gingiva, cementum, periodontal ligament, and the alveolus—and have been loosely described as “periodontal mechanoreceptors.” In addition, the chapter also investigates the fate of these neurones following tooth loss. In conclusion, mechanoreceptors in the periodontal ligament represented in the mesencephalic nucleus are situated in the intermediate area of the ligament between the fulcrum and the apex of the tooth, but are unequally distributed around the tooth root." @default.

LOD is a set of principles of publishing data on the Web in a machine-readable way so that links between different data sets, possibly published by different publishers, can be created. Therefore, LOD enable not only to publish data but also enrich with other existing data published according to the principles. We present what is the motivation for publishing legislation as LOD and what benefits can be gained. We then introduce a legislative ontology which builds on existing commonly used ontologies. We also show how we converted existing sources of legislation in Czech Republic to LOD." @default.

- W1000251042 abstract "Radiofrequency ablation (RFA) is a radical treatment for both primary and recurrent small hepatocellular carcinoma (HCC) with an optimistic outcome which is comparable with surgery. For localized recurrence of HCC after liver transplantation (LTx), surgical resection is considered the most favorable treatment. When surgical resection is contraindicated or technically infeasible, whether RFA is as efficient after transplantation as in nontransplant settings remains unclear.A cohort study was undertaken in a population of patients that had a recurrence of HCC after LTx to evaluate the outcomes of different modalities (surgery, RFA, and conservative therapy) on long-term survival.Seventy-eight of the 486 HCC patients who received LTx had a recurrence (16%). Fifteen patients underwent surgical resection, and 11 patients were treated with RFA. The remaining 52 patients received conservative therapy (17 patients with sirolimus plus sorafenib regimen; the others were treated with conventional supportive therapy). The 1-, 3-, and 5-y overall survival rates were 92%, 51%, and 35% for the patients treated with surgery and 87%, 51%, and 28% for the patients that received RFA. The corresponding 1-, 3-, and 5-y rerecurrence-free survival rates were 83%, 16%, and 16% for the patients treated with surgery and 76%, 22%, and 0% for the patients that received RFA, respectively. There was no significant difference in overall survival or rerecurrence-free survival between the surgical resection group and the RFA group (P = 0.879, P = 0.745).For HCC recurrence after LTx, RFA is preferable when surgical resection is contraindicated or technically infeasible and provides comparable long-term survival compared with surgery." @default.
- W1000251227 abstract "Human genome sequencing was started to solve four letter algorithm of the genome to understand the complex nature of human metabolism. However, after completion of Human Genome Project many scientists realized that sequence information alone was not sufficient to solve the biochemical mechanism of the organism through classical approaches. Non-coding parts of the genome produce small conserved ribonucleic acids, miRNAs to control cellular and physiological processes [1, 2]. This breakthrough discovery directed researches to examine role of miRNA in cancer since miRNAs are involved in the development, cell differentiation, and regulation of cell cycle [3]. The first paper of the special issue provides general information of miRNA in cancer research. This thematic issue presents two computational approaches for miRNA identification and their role in cancer. The first one comes from Dr. Wang and his presented work predicts cancer-related miRNAs by using expression profiles in tumor tissues. The work relies on R-squared method to investigate miRNA-mRNA regulatory relationship between miRNAs and mRNAs from different tissues and predicts miRNAs associated with colon, prostate, pancreatic, lung, breast, bladder, and kidney cancer. The second paper by Allmer et al. examines miRNA-gene regulatory networks and their implications in cancer. Their work provides complex network of expression regulation and miRNAs' role in personalized medicine. miRNAs regulate tumor progression and metastasis by interacting with target genes in the cells. Exosomal shuttle small RNAs mediate cell to cell communication and regulate cancer metastasis. The regulation via heterotypic signals in the microenvironment was explained by Dr. Liang and Dr. Yu groups. The rest of the issue highlights the roles of miRNAs on multiple myeloma, non-small cell lung cancer, urological malignancies, myeloid leukemia, and laryngeal squamous cell carcinoma. Proliferation of bone marrow of malignant plasma cells leads multiple myeloma and this accounts for ten percent of the hematological tumors. miRNAs biology in multiple myeloma and miRNA study methods was discussed by Dr. Cho's group along with translational therapeutics. Dr. Papavassiliou highlights recent literature on miRNA-colerectal cancer. miRNA in colorectal cancer regulates tumor specific markers and these markers have oncogenic and tumor suppressive functions as other types of cancer. The paper overviews miRNA biomarkers extracted from plasma and fecal samples and also explain novel therapeutic applications by miRNA delivery and inhibition. Lung cancer is the leading cause of cancer deaths and non-small cell lung cancer shows poor prognosis and recurrence. Drug resistance limits current treatments and miRNA based gene therapy provides an alternative and attractive method for cancer inhibition since dysregulation of specific miRNAs involved in cancer cell resistance. Therefore, Dr. Giovannetti group explains current efforts in developing miRNA mimickers or antagomiRs for drug resistance mechanism. Dr. Ellinger and Dr. Müller present a comprehensive review on urological malignancies. The relationship between miRNAs and urological malignancies including prostate, renal cell carcinoma, testicular cancer, and bladder cancer and current literature were provided. The paper stimulates discussion on various bodily fluids and detectable miRNAs in patients' circulation. Thus, specific emphasis was given on circulating miRNAs and diagnostic-prognostic information. Last two papers of the issue provide roles of specific miRNAs in myeloid leukemia and laryngeal squamous cell carcinoma. Dr. Vasconcelos showed that overexpression of miR-128 decreased acute myeloid leukemia cells and increased the DNA damage. Laryngeal squamous cell carcinoma is the largest subgroup of squamous cell carcinoma in head and neck. And Dr. Guo investigated regulation and expression of three miRNAs; miR-21, miR-106b and miR-375. The paper reported these miRNAs as potential biomarkers for laryngeal squamous cell carcinoma diagnosis. miRNAs involved in several metabolic pathways and their roles are yet to be elucidated. This thematic issue presents current efforts in determination of miRNAs at different cancer types. Each day determined miRNAs are deposited to the databases and scientists give a lot of effort to understand the biogenesis of these small molecules. These scientific studies and approaches are expected to improve current technologies for therapy and biomarker detection." @default.

- W100025210 abstract "In Mary Ainsworth's (Ainsworth et al., 1978) seminal examination of maternal factors that shape the development of the caregiver-infant attachment relationship, maternal sensitivity, responsiveness, and appropriately stimulating play were associated with security of attachment. Mothers characterized as clinically depressed have been consistently reported to be low or inconsistent in these characteristics (e.g., Campbell et al., 2004; Martins & Gaffan, 2000; Teti, Gelfand, Messinger, & Isabella, 1995). Evidence suggests that one mechanism for the relationship between maternal depression and infant attachment may be via the mother's attributional style, or how one generally perceives control of positive and negative events in one's life (Peterson et al., 1982). Although individuals diagnosed with clinical depression typically present with a pessimistic attributional style (perceiving little or no control over events in their lives, or perhaps feeling responsible for primarily negative events), it has been suggested that nondepressed individuals may show a similar attributional style as a precursor to depression or evidence of mild (nonclinical) depression (Peterson et al.). The purpose of the present study was to explore the relationship in a low-risk sample between the mother's attributional style and the quality of the mother-infant attachment relationship to determine whether mothers perhaps prone to depressive thoughts and behaviors may be less likely to have secure attachment relationships with their infants. First, an understanding of how maternal depression contributes to the quality of the attachment relationship is important. Maternal depression may influence infant functioning both directly and indirectly. As Egeland and Sroufe (1981) point out, a deviant childrearing environment, including possibly sad facial expression and flat or inconsistent affect in interaction with the child, parental maltreatment or neglect, and negative maternal attributions toward the child may all influence infant development. Even cognitive development may be affected. Kaplan, Bachorowski, and Zarlengo-Strouse (1999) found that child-directed speech produced by depressed mothers did not promote associative learning in young infants. Children of depressed parents are particularly likely to be faced with physical, or at least emotional, unavailability of parents, or unstable, ineffective interaction patterns for long, unpredictive periods of time (Cicchetti, Toth, & Rogosch, 1999). They are more frequently exposed to parental sadness and dysphoria, helplessness and hopelessness, and irritability and confusion than children of nondepressed parents (De Wolff & van IJzendoorn, 1997). Maternal depression has been associated with mothers' negative perceptions of (Barnett et al., 1999) and less engagement with (Campbell et al., 2004) their children. Mothers who are dysphoric have been reported to show less emotional expressivity as well with their infants (Halberstadt, Cassidy, Stifter, Parke, & Fox, 1995). In a large-scale NICHD Early Child Care Research Network study (1999), women with chronic symptoms of depression were less sensitive when observed playing with their children from infancy through 36 months than other mothers. Maternal insensitivity has been reported in samples showing a subjective feeling of helplessness in mothers (Spangler & Grossman, 1999). Even in prospective studies, a relation between maternal psychological unavailability (including separation or loss; Bowlby, 1980) and insecurity of attachment has been reported (Radke-Yarrow, 1991). Thus, the main constituents of sensitivity to infant bids for attention--promptness of response, consistency, and appropriateness (van den Boom, 1997)--are uncommon responses by depressed mothers. Depressed individuals tend to have a negative view of the world, and this view may lead to a further propensity toward depression, as one feels more and more helpless in an uncontrollable world. …" @default.

Military medicine has been an area of change over the 10 years of the Australian General Practice Training (AGPT) program. Crisis situations like those in Timor Leste and Afghanistan have focused attention and recognition on the importance of primary health care in the work of the ADF. To train doctors in military medicine, there are several different models at different locations around Australia, as well as large variations in military course and experience recognition and approvals between AGPT regional training providers. At times, the lack of standardisation in training delays the progress of ADF registrars moving through the AGPT program and becoming independently deployable Medical Officers." @default.
- W100025235 abstract "Mutations resulting in the loss of production of specific proteins are among the major causes of inherited diseases. When defective, any of several steps in the gene expression pathway can be the underlying cause of such diseases (Kazazian 1990), but one of the more common types of mutation that inactivates gene function does so by promoting premature translational termination. Nonsense mutations result in the occurrence of UAA, UAG, or UGA codons in the protein-coding region of an mRNA template, leading to the termination of polypeptide elongation and, generally, to the triggering of a cellular surveillance mechanism dubbed nonsense-mediated mRNA decay, or NMD. The NMD pathway is operative in all eukaryotic cells and ensures that nonsense-containing mRNAs do not accumulate as substrates for the translation apparatus. In turn, the elimination of these transcripts prevents the accumulation of potentially toxic polypeptide fragments. NMD has been extensively studied in yeast, worms, flies, and mammals, leading to the identification of a key set of regulatory factors and to the elaboration of models explaining the role of these factors in the discrimination of normal versus premature termination and in the promotion of rapid mRNA decay. These studies have provided insight into cellular quality control mechanisms, elucidated fundamental interrelationships between the pathways of mRNA translation and mRNA decay, and set the stage for a potentially major advance in the treatment of a subset of all genetic disorders.

- W1000253968 abstract "Homocysteine plays a role in the genesis of atherosclerosis and, thus, it is considered an important and prevalent risk factor for peripheral arterial disease. Impaired vitamin nutritional status, especially regarding folate, may be mainly attributed to hyperhomocysteinemia. Although there is still no consensus as to the exact dose and method of use of folate in supplements, dietary adjustment or cereal fortification for the treatment of hyperhomocysteinemia, several studies conducted in patients with peripheral vascular disease have shown that isolated folate may reduce homocysteine levels, as well as the levels of some biological markers in the atherosclerotic process. However, recent studies have not corroborated this benefit for the inflammatory process associated with hyperhomocysteinemia. Consequently, although the use of folate is a cost-effective therapy for the control of hyperhomocysteinemia, its impact on the evolution of vascular diseases remains inconclusive. This literature review addresses the effects of several forms of folate therapies in the treatment of hyperhomocysteinemia." @default.
- W100025404 abstract "In Phase I of the program, we developed the basic tools needed to build a high-frequency air breakdown model. We developed a Quasi-Equilibrium Methodology (QEM) for extending fluid electron transport models to the nonequilibrium regime, based on assuming that the transport coefficients relax toward their equilibrium values on time scales quantified by time-dependent Boltzmann equation solutions. Our analysis of nonequilibrium electron transport discovered and explained a velocity overshoot effect that is not generally known. That tendency of the electrons to overshoot the equilibrium drift velocity is shown to have a profound effect on streamer behavior. We examined the extent of possible simplifications to our kinetic air breakdown model, concluding that factors of 2 to 5 speed-up are possible. We have identified the major phenomenological issues in a modeling strategy, and examined nonequilibrium effects on ionization waves. Finally, we present a plan to complete development of a computational model of High Frequency air breakdown suitable for incorporation into EMP coupling codes, including model verification experiments and implementation of the computer module in an existing EMP coupling code.

- W100025411 abstract "First-principle studies of edge pedestal microinstabilities are performed with a coupled global gyrokinetic GEM-XGC0 simulation. The code coupling is implemented under the End-to-End Framework for Fusion Integrated Simulation (EFFIS).The equilibrium density, temperature and radial electric field (Er) profiles are calculated by the XGC0 code and the anomalous transport coefficients are calculated by the GEM code. The turbulence from simulation results peaks at the position of strongest pressure gradient and hence the minimum Er. The dominant linear instability is driven by the strong density gradient. As a result, the H-mode pedestal is linearly more unstable than L-mode. However, the nonlinear steady-state flux level of H-mode is indeed lower than L-mode. The linear instability requires kinetic electrons but is not due to trapped electrons, and it is nearly insensitive to ion and electron temperature gradients. Hence, the dominant instability is likely to be electron drift wave. It is also found in the pedestal that Er nearly balances the diamagnetic pressure term in the radial force balance equation." @default.

Smoking prevalence was based on data from the VA's 1999 Large Health Survey of Enrollees. A subsample of sites was classified as having restricted access to SCAs if patients were required to attend smoking cessation classes. Changes in annual SCA utilization rates and expenditures by SCA type and restriction status were measured to assess changes in treatment of tobacco dependence.Approximately 7% of smokers received SCA prescriptions, and SCAs accounted for less than 1% of the VHA's annual outpatient pharmacy budget in any given year. Following downward trends in the cost of 30-day SCA prescriptions, annual SCA expenditures per patient decreased over time. Expenditures were lower for restricted than unrestricted sites. More than two thirds of smokers who were prescribed medications received the nicotine patch, a quarter received bupropion sustained-release, and fewer than 10% received nicotine gum.Measures of SCA utilization and cost are low, stable, and less than the recommended rates in national smoking cessation guidelines, suggesting that this population of smokers is undertreated.

Parallel I/O is used to transfer bytes of data at a time between a microcomputer and a peripheral device (such as a printer). Several control signals are present in order to achieve “handshaking”—a process that controls the exchange of data between the computer system and the printer. The Centronics interface has become established as the most commonly used interface standard for the transfer of data between a PC and a printer. The standard employs parallel data transmission (a byte is transferred at a time) and is based on a 36-way Amphenol connector. This chapter explains the principles of parallel I/O, the Centronics interface standard, and the basic fault finding and troubleshooting procedures that can be applied to the parallel interface." @default.

- W1000256098 abstract "Abstract The period of puberty represents a transition from the period of growth to complete somatic and sexual maturity. The menarche , or the appearance of the first menstruation, is a single event in the course of puberty. It does not denote either the end point or the beginning of the pubescent period. It bears a definite relationship to body growth, but the development of the secondary sexual characters begins before and continues after the first menses. The menstrual cycles during the first few years are characterized by marked irregularities, are frequently separated by long periods of amenorrhea, and are functionally incomplete, since a comparative sterility probably exists. With the exception of abnormal uterine hemorrhage, the treatment of functional menstrual disorders during this time should consist primarily of general hygienic measures rather than of attempts to directly influence the pelvic organs." @default.

- W1000257390 abstract "Abstract Background Commuting stress is known to be a root of many problems, including cardiovascular problems such as increased heart rate, increased blood pressure, back problems, as well as certain types of cancer. Examining how travel stress (or enjoyment) varies through time and space may reveal previously unknown relationships among active commute modes, intangible/tangible urban context, and daily weather. The present study set out to investigate these linkages using Geographic Information Systems (GIS) and space-time modeling techniques. Methods This research utilized exploratory spatiotemporal analysis and modeling of alternative commuter sentiment. Social media data was retrieved from twitter users in 6 metropolitan cities in the U.S., emotional content in the form of pleasure/arousal/dominance was extracted from it, spatial and aspatial data was obtained from various federal and local sources. A spatiotemporal weight was developed based on the space and time differentials for each daily tweeter. Exploratory analysis consisted of analyzing spatiotemporal patterning of tweeters using GIS techniques. Specifically, activity space analysis, surface estimation, spatial autocorrelation analysis (Getis-Ord hotspot analysis), global regression, and a spatiotemporal regression model was instituted. Results Preliminary exploratory analysis found that the majority of commuters tweeted once per day. When tweets were examined yearly, it was found that seasonality greatly affected commute sentiment patterns. Space-time weighted activity spaces varied significantly from un-weighted spaces. Furthermore, a weighted inverse-distance-weighted model demonstrated that travel mode affects human sentiment in both time and space. When hotspot analysis was visually examined in 3D, unique sentiments based on travel mode were observed in space and time. A global spatiotemporal regression model (OLS) indicated that weather, car usage, and mass-transit affected human sentiment (p-value Conclusions This analytical framework should be of interest to transportation planners seeking to understand how to promote alternative travel modes as well as health policy researchers studying the effect of commuting infrastructure on commuter’s well-being using a live, streaming dataset." @default.

- W100025829 abstract "The serA gene in Escherichia coli encodes 3-phosphoglycerate dehydrogenase, which is the first enzyme in the serine biosynthesis pathway. Previous studies have determined two different transcription initiation sites for the serA gene, corresponding to the promoters of serA P1 and P2, and suggested that P1 and P2 were regulated by leucine responsive regulatory protein (Lrp) by different mechanisms. However, very little is known about how the two promoters function in different cell growth conditions, and whether other regulator(s) are involved in expression and regulation of serA . In this study, I confirm that Lrp activates P1 but represses P2 in glucose minimal medium by studying native and mutant promoters as serA::IacZ operon fusions. Transcription can take place from both P1 and P2 promoters when Lrp is absent. Furthermore, my study demonstrates that the cyclic AMP (cAMP) receptor protein-cAMP (cAMP-CRP) complex may positively regulate serA by activating P2 and is mainly functional in the absence of Lrp." @default.

This study considered how discrepancies between ideal and perceived actual body image differed in between male and female third year sport and exercise science university students. Participants completed questionnaires that examined body image, self esteem, and awareness of socio-cultural attitudes towards appearance. The Body Image States Scale (Cash et al., 2002), State Self-Esteem Scale (Heatherton & Polivy, 1991) and the Situational lnventory of Body Image Dysphoria - Short form (SIBID-S) (Cash, 2002). Additionally, female participants completed the Sociocultural Attitudes Towards Appearance Questionnaire (SATAQ) (Heinberg, Thompson & Stormer, 1995). A same-sex computer image was then manipulated to reflect the participant's perception of their ideal and current body shape (Maschette & Sands, 2003). Male (N=15) and female (N=29) participants participated (reword??) reported equally participation in physical activity (2 (1, 44)=0.09, p>0.05), while 54.5% of male and female participants included identified weight training as part of their regular exercise regime. Discriminant function analysis revealed one significant function (λ = 0.46, p<0.01) indicating that female participants were more likely to report negative body image perceptions and a belief that their thighs size was larger than the those of an idealised female body. In contrast, male participants were more likely to report a positive body image perception and a belief that their thigh sizes were smaller than the idealised male body. Classification procedures correctly classified 86.4% of participants into their respective gender. Female participants with increased awareness of the sociocultural attitudes towards appearance reported increased levels of anger (r=0.40, p<0.05) and negative body image (r=0.41, p<0.05) and lower levels of social (r=-0.46, p<0.05) and appearance self-esteem (r=-0.44, p<0.05).

The need to develop systematic procedures to assist the designers has been wide because the trial and error technique is the unique often available (Figueiredo & Gomide, 1997). In general terms, for applications involving system identification and fuzzy modeling, it is convenient to use energy functions that express the error between the desired results and those provided by the fuzzy system. An example is the use of the mean squared error or normalized mean squared error as energy functions. In the context of systems identification, besides the mean squared error, data regularization indicators can be added to the energy function in order to improve the system response in presence of noises (from training data) (Guillaume, 2001). In the absence of a tuning set, such as happens in parameters adjustment of a process controller, the energy function can be defined by functions that consider the desired requirements of a particular design (Wan, Hirasawa, Hu & Murata, 2001), i.e., maximum overshoot signal, setting time, rise time, undamped natural frequency, etc. From this point of view, this article presents a new methodology based on error backpropagation for the adjustment of fuzzy inference systems, which can be then designed as a three layers model. Each one of these layers represents the tasks performed by the fuzzy inference system such as fuzzification, fuzzy rules inference and defuzzification. The adjustment procedure proposed in this article is performed through the adaptation of its free parameters, from each one of these layers, in order to minimize the energy function previously specified. In principle, the adjustment can be made layer by layer separately. The operational differences associated with each layer, where the parameters adjustment of a layer does not influence the performance of other, allow single adjustment of each layer. Thus, the routine of fuzzy inference system tuning acquires a larger flexibility when compared to the training process used in artificial neural networks. This methodology is interesting, not only for the results presented and obtained through computer simulations, but also for its generality concerning to the kind of fuzzy inference system used. Therefore, such methodology is expandable either to the Mandani architecture or also to that suggested by Takagi-Sugeno." @default.
- W100025994 abstract "A significant problem in inertial confinement fusion is that the material interfaces in the converging flow are subject to the Richtmyer-Meshkov instability when they are impulsively accelerated. It has been demonstrated that this instability can be suppressed in magnetohydrodynamic (MHD) flows at least for flow configurations with rectangular geometry. In order to understand the flow induced by attempting such suppression in converging flow configurations, it is necessary first to investigate the underlying base-flows, the canonical versions of which correspond to converging cylindrical and spherical MHD Riemann problems. Here, we present the numerical solution to one such case: the cylindrical MHD Riemann problem shown below with a uniform initial magnetic field of strength β = 2 and a pressure ratio of three across the interface. The wave structure is initially characterised by two outward- and two inward-moving waves, but as the solution develops, discontinuities form along the waves, producing a more complex flow structure. We investigate the different flow structures, their formation times, and identify how the compression achieved at the centre of the implosion is affected by the magnetic field." @default.
- W1000260502 abstract "This thesis explores data fusion and distributed robotic perception through a series of theoretical developments, analyses and experiments. First, a GSF with component extended Kalman filters (EKF) is proposed as an approach to localize an autonomous vehicle in an urban environment with limited GPS availability. The GSF is used because of its ability to represent the posterior distribution of the vehicle pose with better efficiency (fewer terms, less computational complexity) than a corresponding bootstrap particle filter with various numbers of particles due to the interaction with measurement hypothesis tests. A series of in-depth empirical studies are performed using 37 minutes of recorded data from Cornell University’s autonomous vehicle driven in an urban environment, including a 32 minute GPS blackout. Second, a distributed grid-based terrain mapping algorithm using Gaussian Mixture Models is developed for use in tree connected and arbitrary connected sensor networks. The distributed data fusion rules are developed that operates directly on the sufficient statistics summarizing the grid-cell height and uncertainty. The distributed grid-based terrain mapping algorithms is demonstrated in an experimental environment involving 8 autonomous robots operating in an indoor environment for 120 seconds. Third, an algorithm to segment 3D points in dense range maps generated from the fusion of a single optical camera and a multiple emitter/detector laser range finder is presented. The algorithm is demonstrated on data collected with the Cornell University DARPA Urban Challenge vehicle. Finally, two information theoretic procedures for fusing multiple distributions with unknown correlation are developed. The first approach developed is Entropy Weighted Chernoff fusion; this fusion procedure biases the WEP fusion weight towards the distribution with the lowest entropy. An information loss for the WEP conservative fusion rule is introduced and an approximation derived by computing the Kullback-Leibler divergence between the Naive Bayes and WEP fused distributions. The approximation is minimized for the second fusion approach: Minimum-Information-Loss fusion; the procedure generates the least conservative fused distribution in the family of WEP results. Experimental results include the fusion of multiple occupancy grid maps over an optimally connected sensor network, demonstrating consistent map estimates." @default.

The results indicate that two kinds of biomass straw can be mixed fully. The pyrolysis process with its blend ratio is not a linear relationship and solid product reduced compared with single-stalk. In addition, the major pyrolysis process of mixture within the main range can be well described by a two-dimensional diffusion model with Malek method. Among the tested samples, the 40:60 MG/ YM blend shows the lowest activation energy of 51.7 KJ/mol. Besides corn straw plays a dominant role on the course of the thermal conversion.

The materials were processed by spark plasma sintering technique. Si3N4 with fine, average and coarse microstructures were obtained. Load versus displacement curves (P–h) were obtained by means of instrumented indentation technique using diamond coni-spherical tip. The experimental data were coupled with a minimization method based on the Levenberg–Marquardt algorithm and the non-linear part of the mechanical response was identified. Based on the obtained stress–strain curves, rolling contact simulations were performed. In addition, the nature of Hertzian contact damage was examined in the material with coarse microstructure using diamond indenters of radii 0.2 and 1 mm. The surface damage was observed under optical microscopy while Focused Ion Beam Sectioning technique permitted to image the subsurface damage. An evident size effect was noticed: fracture consisting of classical ring cracks dominated at large scale while distributed microcracks beneath the indent dominated at small scale." @default.
- W1000261187 abstract "Moorea producens JHB, a Jamaican strain of tropical filamentous marine cyanobacteria, has been extensively studied by traditional natural products techniques. These previous bioassay and structure guided isolations led to the discovery of two exciting classes of natural products, hectochlorin (1) and jamaicamides A (2) and B (3). In the current study, mass spectrometry-based ‘molecular networking’ was used to visualize the metabolome of Moorea producens JHB, and both guided and enhanced the isolation workflow, revealing additional metabolites in these compound classes. Further, we developed additional insight into the metabolic capabilities of this strain by genome sequencing analysis, which subsequently led to the isolation of a compound unrelated to the jamaicamide and hectochlorin families. Another approach involved stimulation of the biosynthesis of a minor jamaicamide metabolite by cultivation in modified media, and provided insights about the underlying biosynthetic machinery as well as preliminary structure-activity information within this structure class. This study demonstrated that these orthogonal approaches are complementary and enrich secondary metabolomic coverage even in an extensively studied bacterial strain." @default.

- W1000262338 abstract "General nature of yield or failure criteria terminating elastic range of isotropic or anisotropic materials is summarized. As shown, the hydrostatic pressure sensitivity of anisotropic materials can be captured either by first stress and second common deviatoric invariant direct use (Tsai–Wu), or by the second common stress invariant in an indirect fashion (von Mises). Tension/compression asymmetry in anisotropic materials is accounted for either by presence of first common invariant (only translation, Tsai–Wu) or third common invariant (distortion, Kowalsky). Comparison of two ways to capture anisotropic response, more rigorous explicit common invariants formulations or implicit approaches based on extension of traditional isotropic criteria in terms of transformed invariants (Barlat, Khan) capable of capturing a complete distortion, is shown. Convexity requirement of limit surfaces is discussed and compared for two material behaviors by the use of Drucker’s material stability postulate extended to multi-dissipative response or Sylvester’s stability condition based on positive definiteness of the tangent stiffness or compliance matrices of hyperelastic material. Generalized Drucker’s postulate based on elastic–plastic stiffness matrix is also shown." @default.

This time series estimator approximates the irregular data by a number of equidistantly resampled missing data sets, with a special nearest neighbor method. The ARMAsel-irreg algorithm estimates and automatically selects a discrete-time AR model from a number of candidates. This selected model often has a number of spurious high frequency poles, which are incompatible with the continuous character of the irregularly sampled signal. Those spurious poles can be eliminated, by transforming only the poles of the discrete time model with a positive real part to matching continuous-time poles. The estimated continuous-time spectra can be accurate at frequencies much higher than the mean data rate." @default.

The incidence of AIDS-related lymphoma in some developing countries such as Brazil is increasing as the survival of HIV infection has improved. Although there is a clear association between several types of immunodeficiency-related lymphomas and Epstein-Barr virus (EBV), the association of EBV infection in AIDS-related lymphoma in Brazil, where the incidence of AIDS is high, is unknown. Formalin-fixed, paraffin-embedded tissue from 24 cases of AIDS-related lymphoma in Brazil were analyzed for morphologic classification, immunophenotype, and EBV association using in situ hybridization studies with an EBV-EBER1 biotinylated probe. Twenty cases of AIDS-related lymphoma were classified as non-Hodgkin’s lymphoma and four cases were Hodgkin’s disease. Eleven non-Hodgkin’s lymphomas were classified as diffuse large cell type, five cases were small non-cleaved cell, Burkitt-type, and four cases were large cell immunoblastic non-Hodgkin’s lymphoma. Eighteen cases were of B-cell phenotype; one was a T-cell lymphoma, and one was classified as null. Epstein-Barr virus (EBV) was demonstrated in the majority of tumor cells of 11 of 20 (55%) of the cases non-Hodgkin’s lymphomas and in 3 of 4 (75%) cases of Hodgkin’s disease.

LAK cell cytotoxicity is predominantly mediated by CD3-/CD56+ activated natural killer (NK) cells and only to a small degree by MHC-unrestricted CD3+/CD56+ T cells (Phillips and Lanier 1986; Herberman et al. 1987; Tilden et al. 1987; Saito et al. 1988). Human leukemia cells possess a distinct LAK cell susceptibility which varies considerably in different subtypes of leukemia (Teichmann et al. 1992). Maximal cytolysis by activated effector cells is desirable for therapy. The current study therefore aimed at investigating whether in vitro exposure of leukemic cells to cytotoxic agents, relevant for leukemia treatment, can augment the susceptibility of fresh noncultured leukemia cells to LAK cell lysis.

The article introduces a study on wage differentials between men and women in Finland. It is based on exceptionally large data, consisting of linked population census and tax registers and covering the whole salaried population in 1985. The most detailed level of the Finnish Occupational Classification containing 390 occupational categories is used. In addition, wage differentials are studied by branches and sectors of economic activity and by age, education and family stage. The results show that occupations tend to be segregated according to gender. Only 9 per cent of employees work in occupations in which the proportions of men and women are equal. Wage differentials are smallest in the most female-dominated occupations and increase steadily when moving towards more male-dominated occupations. In other words, wage differentials would seem to be due to the predominance of men in an occupation rather than to segregation." @default.

In this study we investigated how to improve the performance of 3G serving from HAP over a territory having suburban characteristics. Two proposed channel models, free space loss and shadowing loss, has been used to analyze the performance of HAP systems at 2GHz frequency band for suburban regions. Three different parameters namely antenna bore point, HAP antenna roll off factor and user antenna roll off factor have proposed to improve the performance of HAP systems while considering suburban regions. A scenario has introduced consisting of an ideal suburban and rural region to serve 3G services while emphasizing on suburban region. The number of HAPs required to serve the defined suburban region is restricted to at least three due to elevation dependent losses in the scenario. The three proposed parameters have been used to improve the performance of 3G services over the selected suburban region. Application of the parameters over suburban region gives different performances which can be categorized in different ways.

- W100027011 abstract "In recent years, a growing field of research in “Adaptive Systems” has resulted in a variety of adaptive automatons whose characteristics in limited ways resemble certain behaviors of living systems and biological adaptive processes. The essential and principal property of the adaptive systems is its time-varying, self-adjusting performance by using a process called “learning” from its environment. A channel equalizer is a very good example of an adaptive system, which has been considered in this work to assess its performance with reference to various novel learning algorithms developed.The two main threats for the digital communication systems are Inter-symbol Interference (ISI) and the presence of noise in the channels which are both time varying. So, for rapidly varying channel characteristics, the equalizer too need to be adaptive. In order to combat with such problems various adaptive equalizers have been proposed. Particularly, when the decision boundary is highly nonlinear, the classical equalizers (so called linear ones) do not perform satisfactorily.The use of Artificial Neural Networks (ANNs) provides the required nonlinear decision boundary. The Back Propagation (BP) algorithm revolutionized the use of ANNs in diverse fields of science and engineering. The main problem with this algorithm is its slow rate of convergence. But the high speed digital communication systems, in the presence of rapidly fading channels, demand for faster training. To overcome this problem a faster method of training the neural network using RLS algorithm is proposed in this thesis work.But both the BP and RLS based BP algorithms belong to the family of Gradient-based algorithms, which have the inherent problem of getting trapped in local minima. Since obtaining a global solution is the main criterion for any adaptive system, an efficient search technique is highly desirable. Tabu Search serves this purpose.The popularity of Tabu Search (TS) has grown significantly in the past few years as a global search technique. In this dissertation, it is proposed to find the so-called optimal values of the ANN parameters (slopes and weights) for channel equalization. Results show that the use of TS for adapting the weights and slopes for an ANN not only improves the performance of the equalizer but also reduces the structural complexity of the ANN." @default.

Cet article dégage alors trois dimensions à cette catégorie pratique de connaissances : symbolique, technique et politique. En conclusion, l'intégration étroite du processus de connaissances au quotidien professionnel des acteurs institutionnels est soulignée, tout en reconnaissant que la prise en compte du paysage fait émerger de nouveaux objets d'intervention. Apparaît alors une catégorie en constitution où s'expriment l'influence du paysagisme et l'idée de naturalité." @default.
- W100027130 abstract "Viral and protozoal infections are often suspected as causes of neonatal illness or congenital anomalies. The TORCH titer has traditionally been the foremost diagnostic tool in this context, but it is now becoming increasingly clear that this tool is inadequate, partly for conceptual reasons, but also because of the often uncritical way in which it is used. During a recent critical review of our routines and practices for diagnosis and treatment of neonatal infections we also revised our approach to the diagnosis and treatment of suspected pre- or perinatally acquired viral, spirochetal, and protozoal illnesses. The resulting guidelines, originally intended for our house staff, are presented here." @default.
- W1000271657 abstract "Knowledge of sediment sources and their dispersal across the landscape is essential for understanding the dynamics of flood plain ecosystems. This is important for flood plain management because rates of upstream catchment erosion are predicted to increase considerably throughout much of inland Australia. In this study, the provenance and dispersal of sediment across a large lowland flood plain complex are investigated. A range of non-soluble geochemical elements were used in a Bayesian mixing model to determine the source and dispersal of very fine sand and clay sized particles across the lower Balonne flood plain in SE Australia. These two sediment fractions were chosen because they are the dominant material present within this flood plain complex. The relative contribution of the two main sediment sources differed for each of the sediment fractions. Clay sized particles were predominantly derived from the Maranoa catchment, whereas the very fine sand was derived from the Condamine catchment. In terms of the dispersal of these sediment fractions from the two main sources, very fine sands were dispersed relatively uniformly across the Lower Balonne flood plain, whereas the clay sized sediment was restricted to the main flow channels that dissect this flood plain. These spatial patterns are contrary to that expected in terms of the dispersal ability of sediment across flood plain surfaces and result from the complex hydrology of the flood plain surface along with the timing of flow events originating from the two tributaries." @default.

- W1000271762 abstract "There are many factors that affect SMEs' ability to borrow from bank. Based on facts and data about SMEs' financing in Chengdu city, capital of Southwestern China's Sichuan province, this paper is intended to investigate the factors affecting SMEs to borrow from bank by methods of empirical study. We find that whether SMEs can provide collateral or guarantee is a decisive factor, factors such as firm size, willingness to accept bank's clauses, close relationship with bank play an important role. But in contrast to intuition, correlation analysis and regression result shows that SMEs' financial variables such as income, net profit, asset-debt ratio and credit score is not obvious to affect their ability to get bank loan. Consistent with theory prediction and qualitative analysis, firm size is the most important factor to affect SMEs' ability to borrow from bank. The regression results reflect information asymmetry between SMEs and banks, and that banks had taken a simple way to protect themselves." @default.
- W1000272099 abstract "Objective To analyze the protein expression in the rat hippocampus by the proteomic approach.Methods Proteins from hippocampal tissue homogenates of the rat were separated by two-dimensional gel electrophoresis(2-DE),and stained with colloidal Coomassie blue to produce a high-resolution map of the rat hippocampus proteome.Selected proteins from this map were digested with trypsin,and the resulting tryptic peptides were analyzed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry(MALDI-TOF-MS).The mass spectrometric data were used to identify the proteins through searches of the NCBI protein sequence database.Results 37 prominent proteins with various functional characteristics were identified.The identified brain protein classes covered metabolism enzymes,cytoskeleton proteins,heat shock proteins,antioxidant proteins,signalling proteins,proteasome-related proteins,neuron-specific proteins and glial-associated proteins.Furthermore,3 hypothetical proteins,unknown proteins so far only proposed from their nucleic acid structure,were identified.Conclusion This study provides the first unbiased characterization of proteins of the rat hippocampus and will be used for future studies of differential protein expression in rat models of neurological disorders." @default.
- W10002721 abstract "We define a simple model of a map and formulate geometrical integration as a transformation problem between one idealized true map only known partially and multiple realizations of the map perturbed by random noise and unknown systematic effects. In the statistical model the connection between the true map and its realizations is interpreted as a multivariate spatial random process and further investigated by geostatistical and classical estimation methods. As a main result a model of the distance-dependent relative accuracy (neighborhood accuracy) in spatial datasets is obtained. On the basis of this statistical hypothesis two models for the estimation of the true map, namely intrinsic kriging and collocation, are suggested. As an alternative to the stochastical model we suggest the deterministic model of the topology of the euclidean plane where the connection between the maps is treated as a homeomorphism. The consideration of constraints in form of a bijection for homologous points and nonlinear functions for geometrical constraints leads to the formal definition of the homogenization of maps. An extension of the collocation model allows us to estimate the unknown parameters (coordinates) in the system of the true map and to simultaneously consider geometrical constraints, the linear trend, the nonlinear signal and the random noise. Due to the high density of its design matrix the suggested model is unsuitable for practical applications with mass data. The hybrid approach of Benning appears to be an optimal compromise between the extended collocation model and other alternatives. It has the advantage that statistical least squares methods can be combined with (efficient) deterministic interpolation methods and furthermore leads to a sparse design matrix." @default.

- W1000272827 abstract "When lethal injection was first legalized in the late 1970s, many people viewed it as safe, reliable, and humane. Today, however, lethal injection does not always perform as promised. Due to difficulties with sourcing lethal injection drugs, states are utilizing untested lethal injection protocols, with little knowledge or experience to guide them. This article argues that lethal injection reform requires regulation similar to that for human subject research, and that the practice of utilizing untested lethal injection methods comes very close to falling under the federal statutory definition of “human subject research“ formulated in the Common Rule. This article argues further that even if one decides that it does not, the practice of lethal injection today is the type of conduct that the human subject research regulations were designed to correct. Moreover, society has an interest in ensuring that executions are conducted in a way that reduces pain and suffering to the lowest extent possible. As such, lethal injection ought to receive further review and oversight to ensure that it comports with reasonable notions of humanity." @default.

- W1000275774 abstract "The atomic configurations and structural evolution of disordered Cr2N have been investigated by CS-corrected high-resolution transmission electron microscopy (HRTEM) imaging, electron diffraction analysis, electron energy loss spectroscopy (EELS) and ab initio calculations. The atomic structure of the disordered Cr2N is experimentally confirmed by CS-corrected atomic resolution imaging. Both diffraction and HRTEM image analysis revealed that the disordered Cr2N structure possesses a hexagonal (hcp) arrangement of Cr atoms with N atom random distributions, particularly, N atoms shift away from octahedral interstices at (0 0 1) plane. The nitrogen atom shifts result in a clear reduction of the relative intensity ratio of (0 3 0) to (0 0 2) reflection. It has also been found that the disordered Cr2N can transform into a face-centered cubic (fcc) phase at the specimen surface while chemically retaining a Cr/N atomic ratio close to 2:1. Structurally, such cubic phase is similar to sub-stoichiometric fcc CrN. The analysis corroborated that the structural transformation could be achieved by shearing motion of Cr atoms in (0 0 1) planes. Based on the experimental observations and theoretical calculations, the effects of nitrogen atom redistribution on the structure and the stability of various Cr2N phases are addressed in detail." @default.

- W1000276811 abstract "Cobalt-chromium-molybdenum (CoCrMo) alloy-based metal-on-metal prostheses have been the implant of choice for total hip replacement in younger patients. However 6.2% of patients require revision of their CoCrMo total hip replacement (THR) implant within five years of surgery and their use was restricted in 2013. We aimed to determine if there were individual differences in the immune response to wear debris that might indicate a poor outcome with a CoCrMo prosthesis. Blood from 22 donors was incubated with CoCrMo particles (>99.9% less than 10 μm diameter) generated by a wear simulator for 24 h. T cell phenotype was assessed by immunostaining and secretion of 8 different pro- and anti-inflammatory cytokines was measured using multiplex technology. Clear differences were seen between individuals in the induction of Th17 and Th1 responses, with some donors showing pro-inflammatory responses (increased IL17 or IFNγ) and others showing anti-inflammatory responses (decreased IL17 or IFNγ). The only differences seen for gender and age related to increased IL-10 expression from T cells in females (p = 0.008) and a trend towards decreased IL-6 expression systemically for older donors (p = 0.058). We conclude that individuals show differential responses to CoCrMo wear debris and that these responses could give early indications of the suitability of the patient for a metal-on-metal prosthesis." @default.

- W1000277523 abstract "The purpose of Exploration in Oil Industry is to discover an oil-containing geological formation from exploration data. In the context of this PhD project this oil-containing geological formation plays the role of a geometrical object, which may have any shape. The exploration data may be viewed as a cloud of that is a finite set of points, related to the geological formation surveyed in the exploration experiment. Extensions of topological methodologies, such as homology, to point clouds are helpful in studying them qualitatively and capable of resolving the underlying structure of a data set. Estimation of topological invariants of the data space is a good basis for asserting the global features of the simplicial model of the data. For instance the basic statistical idea, clustering, are correspond to dimension of the zero homology group of the data. A statistics of Betti numbers can provide us with another connectivity information. In this work represented a method for topological feature analysis of exploration data on the base of so called persistent homology. Loosely, this is the homology of a growing space that captures the lifetimes of topological attributes in a multiset of intervals called a barcode. Constructions from algebraic topology empowers to transform the data, to distillate it into some persistent features, and to understand then how it is organized on a large scale or at least to obtain a low-dimensional information which can point to areas of interest. The algorithm for computing of the persistent Betti numbers via barcode is realized in the computer algebra system Singular in the scope of the work." @default.

- W100027900 abstract "In the upcoming years, significant changes in the profile of satellite missions are expected as scientists and managers want to benefit from multi-satellite missions. Among others, distributed or virtual satellite platforms will create a completely new class of space missions, where not one single spacecraft or payload segment has to be operated but a formation or constellation of satellites. A “formation” designates multiple satellites in close proximity and is typically characterized by demanding guidance, navigation and control requirements. In comparison to perform these tasks by a ground control approach, on-board autonomy can guarantee superior performance with respect to control accuracies and cost efficiency.A dedicated research and development program on “Autonomous Spacecraft Navigation and Formation Flying” was initiated at DLR/GSOC in 1998. Numerous contributions in the area of space-borne GPS receiver technology, precision relative navigation and autonomous orbit control of satellite formations as a prerequisite for spacecraft autonomy have been made. Practical experience in the operations of a two-satellite formation has been gained by the GRACE mission. Next, GSOC is supporting Swedish Space Cooperation (SSC) in the implementation of the PRISMA formation flying demonstration mission, where a fully autonomous, robust and precise formation flying of spacecraft will be conducted by experiment. Finally, the German TerraSAR-X/TanDEM-X radar satellites will be Europe’s first space mission equipped and operated routinely with an autonomous formation flying system." @default.

This is why this question has been the subject of discussion and controversy in the history of religious thought and became early on a subject of discussion between Muslim Mutakallimuns and Christian theologians belonging to the different eastern churches. The present work intends to introduce this interreligious debate by presenting texts of some of the Christian authors who wrote in Arabic. While defending human free will, these authors tried to reconcile it with the divide omnipotence, with god's foreknowledge and providence. At the same time, they tried to respond to existential questions like the problem of evil and the inequalities among persons. And they attempted, finally, to present the Christian conception of the relationship between God and the human person." @default.
