| left lateralization in autobiographical memory: an fmri study using the expert archival paradigm. | in brain-imaging and behavioral research, studies of autobiographical memory have higher ecological validity than controlled laboratory memory studies. however, they also have less controllability over the variables investigated. this article presents a novel technique - the expert archival paradigm - that increases controllability while maintaining ecological validity. stimuli were created from games played by two international-level chess masters. the two players were asked to perform a memory ... | 2008 | 18205077 |
| mass effects of quartz resonant sensors with different surface microstructures in liquids. | liquid trapped by the rough surface of a quartz resonator vibrating in thickness-shear mode (tsm) will act as a mass effect to the crystal. it has been proven that this mass effect not only depends on the liquid mass enclosed in the surface cavities, but also the liquid properties and the crystal surface features. based on a series of experiments, this paper introduces "trapping factor" to analyze the mechanism of the liquid mass effect. influences of different surface microstructures, including ... | 1998 | 18244280 |
| facultative cheater mutants reveal the genetic complexity of cooperation in social amoebae. | cooperation is central to many major transitions in evolution, including the emergence of eukaryotic cells, multicellularity and eusociality. cooperation can be destroyed by the spread of cheater mutants that do not cooperate but gain the benefits of cooperation from others. however, cooperation can be preserved if cheaters are facultative, cheating others but cooperating among themselves. several cheater mutants have been studied before, but no study has attempted a genome-scale investigation o ... | 2008 | 18272966 |

| structure analysis of the children's eating attitudes test in overweight and at-risk for overweight children and adolescents. | in school-based samples of children, the children's eating attitudes test (cheat) has a four-factor structure; however, previous studies have not examined its factor structure in samples restricted to overweight youth. | 2008 | 18329601 |
| season of birth and chess expertise. | the origin of talent and expertise is currently the subject of intense debate, with explanations ranging from purely biological to purely environmental. this report shows that the population of expert chess players in the northern hemisphere shows a seasonal pattern, with an excess of births in late winter and early spring. this effect remains when taking into account the distribution of births in the population at large, using statistics from the european union member countries. a similar patte ... | 2008 | 18335581 |
| genetic royal cheats in leaf-cutting ant societies. | social groups are vulnerable to cheating because the reproductive interests of group members are rarely identical. all cooperative systems are therefore predicted to involve a mix of cooperative and cheating genotypes, with the frequency of the latter being constrained by the suppressive abilities of the former. the most significant potential conflict in social insect colonies is over which individuals become reproductive queens rather than sterile workers. this reproductive division of labor is ... | 2008 | 18339809 |
| changes in salivary physiological stress markers associated with winning and losing. | using a representative table game popular in japan known as shogi, or japanese chess, we investigated the effects of winning and losing on saliva composition. the subjects were 90 healthy male university students who were members of a shogi club. saliva samples were collected immediately before and after playing shogi, and again 30 min later. salivary cortisol and testosterone levels in the samples were determined by elisa and eia, respectively. after finishing each game, the competitiveness of ... | 2008 | 18344597 |
| dilemma that cannot be resolved by biased quantum coin flipping. | we show that a biased quantum coin flip (qcf) cannot provide the performance of a black-boxed biased coin flip, if it satisfies some fidelity conditions. although such a qcf satisfies the security conditions of a biased coin flip, it does not realize the ideal functionality and, therefore, does not satisfy the demands for universally composable security. moreover, through a comparison within a small restricted bias range, we show that an arbitrary qcf is distinguishable from a black-boxed coin f ... | 2008 | 18352530 |
| novel transcriptome patterns accompany evolutionary restoration of defective social development in the bacterium myxococcus xanthus. | evolutionary trait losses can be restored by direct reversion or by compensatory pathways. upon starvation, the bacterium myxococcus xanthus develops into spore-bearing fruiting bodies, but this ability can be rapidly lost during evolution. some developmentally defective strains of m. xanthus "cheat" on proficient strains during development by superior sporulation in mixed cultures. here, we examine transcriptomic patterns accompanying the evolution of a cheater (obligate cheater [oc]) to a deve ... | 2008 | 18385222 |
| the early childhood epilepsy severity scale (e-chess). | we have developed the early childhood epilepsy severity scale (e-chess) to quantify the severity of epilepsy in infants and young children with tuberous sclerosis as an aid to the evaluation of treatment efficacy and the investigation of the influence of epilepsy severity on development. | 2008 | 18387786 |

| applying user-generated quality criteria to develop an internet intervention for patients with heart disease. | internet interventions can help people to self-manage chronic disease. however, they are only likely to be used if they meet patients' perceived needs. we have developed an internet intervention in two stages to meet the needs of patients with coronary heart disease (chd). first, user-generated criteria were applied to an existing us-based intervention called 'chess living with heart disease' which provides information, emotional and social support, self-assessment and monitoring tools, and beha ... | 2008 | 18430276 |
| the effects of dynamic movement on seated reach arcs. | the objective of this study was to determine the relationship between movement of the low back and shoulder during a normal seated reach and the reach arc estimation equations found in literature. the method consisted of evaluating individuals who were reaching with their right hands for five chess pawns, which were placed at varying distances. specifically, the pawns were evenly spaced in a straight line directly in front of each participant's shoulder. this study focused on a group of 32 parti ... | 2008 | 18432446 |
| deliberate practice predicts performance over time in adolescent chess players and drop-outs: a linear mixed models analysis. | in this study, the longitudinal relation between deliberate practice and performance in chess was examined using a linear mixed models analysis. the practice activities and performance ratings of young elite chess players, who were either in, or had dropped out of the dutch national chess training, were analysed since they had started playing chess seriously. the results revealed that deliberate practice (i.e. serious chess study alone and serious chess play) strongly contributed to chess perfor ... | 2008 | 18433518 |
| designing for the home: a comparative study of support aids for central heating systems. | the study examined the influence of different types of enhanced system support on user performance during the management of a central heating system. a computer-based simulation of a central heating system, called chess v2.0, was used to model different interface options, providing different support facilities to the user (e.g., historical, predictive, and instructional displays). seventy-five participants took part in the study and completed a series of operational scenarios under different sup ... | 2009 | 18433730 |

| mirrors in the head: cultural variation in objective self-awareness. | in a society where there are pronounced concerns for "face," people come to be especially focused on how they are being evaluated by others. we reasoned that japanese should conceive of themselves in terms of how they think they are considered by others. this hypothesis was tested by contrasting japanese and north american participants who were in front of a mirror with those who were not. in two studies, replicating past research, north americans who were in front of a mirror were more self-cri ... | 2008 | 18453391 |
| mapping of abscisic acid responsive genes and vp1 to chromosomes in wheat and lophopyrum elongatum. | the plant hormone abscisic acid (aba) affects developmental and physiological processes that can impact crop production. these processes include germination, environmental stress responses in vegetative tissue, embryo maturation, and dormancy. identification and molecular tagging of aba-responsive genes, as well as the vp1 gene, required for aba sensitivity, may be valuable in developing breeding strategies designed for manipulating aba-regulated traits. using aneuploid genetic stocks and alien ... | 1994 | 18470064 |
| increased efficacy of zinc complexes with picolinic and aspartic acids against herpes simplex virus (hsv) infection when combined with the pavine alkaloid (-)-thalimonine. | complexes of zinc with picolinic and aspartic acids inhibit key steps of hsv-1 replication affecting different virus-specific targets. as was recently demonstrated by us, the pavine alkaloid (-)-thalimonine irreversibly inhibits hsv-1 infection in cultured cells. the aim of the present study was the evaluation of the combined effect of zinc complexes and (-)-thalimonine on uninfected and hsv-1 infected cells. the data obtained have shown that zinc complexes and the alkaloid exert decreased cytot ... | 2000 | 18475954 |
| fetal-maternal conflict, trophoblast invasion, preeclampsia, and the red queen. | the much publicized conflict hypothesis for understanding fetal-maternal interaction during pregnancy often invokes a 'battle' metaphor, rather than a well orchestrated interplay occurring as a series of well controlled moves and counter-moves as happens in a game of chess. such stepwise interaction is particularly obvious in the spiral artery remodelling process, and it would be interesting to trace the history of the successive steps in histological adaptation throughout primate phylogeny. the ... | 2008 | 18484423 |
| mental imagery and chunks: empirical and computational findings. | to investigate experts' imagery in chess, players were required to recall briefly presented positions in which pieces were placed on the intersections between squares (intersection positions). position types ranged from game positions to positions in which both the piece distribution and the location were randomized. simulations were run with the chrest model (gobet & simon, 2000). the simulations assumed that pieces had to be centered back, one by one, to the middle of the squares in the mind's ... | 2008 | 18491491 |
| patient/caregiver influences for declining participation in supportive oncology trials. | enrolling adequate numbers of subjects to research projects that focus on the supportive needs of patients and caregivers is difficult, and this difficulty significantly impedes investigation of this important research area. we report reasons that patients or their informal caregivers declined to participate in one of two randomized, longitudinal clinical trials testing the comprehensive health enhancement support system (chess), a web-based information and support scheme for people with advance ... | 2008 | 18491685 |
| improvement of vessel visibility in time-of-flight mr angiography of the brain. | to improve vessel visibility in time-of-flight mr angiography (tof-mra) by careful consideration of coil choice, coil position, and frequency offset and profile of the nonspatially selective chemical shift selective (chess) presaturation pulse. | 2008 | 18504756 |
| a framework for addressing the global obesity epidemic locally: the child health ecological surveillance system (chess). | childhood obesity has reached epidemic levels in the developed world. recent research and commentary suggest that an ecological approach is required to address childhood obesity, given the multidimensional nature of the problem. we propose a canadian prototype, the child health ecological surveillance system, for a regional health authority to address the growing obesity epidemic. this prototype could potentially be used in other jurisdictions to address other child health issues. we present 8 g ... | 2008 | 18558045 |
| why good thoughts block better ones: the mechanism of the pernicious einstellung (set) effect. | the einstellung (set) effect occurs when the first idea that comes to mind, triggered by familiar features of a problem, prevents a better solution being found. it has been shown to affect both people facing novel problems and experts within their field of expertise. we show that it works by influencing mechanisms that determine what information is attended to. having found one solution, expert chess players reported that they were looking for a better one. but their eye movements showed that th ... | 2008 | 18565505 |
| the effect of susceptibility of gadolinium contrast media on diffusion-weighted imaging and the apparent diffusion coefficient. | the development of parallel magnetic resonance imaging has resulted in the frequent use of diffusion-weighted imaging (dwi) in clinical medicine, which usually involves the use of contrast medium. however, gadolinium (gd) contrast medium may have some effect on dwi and the apparent diffusion coefficient (adc). the present study was performed to determine whether the magnetic susceptibility of contrast medium alters the dwi signal and the value of adc in some imaging techniques. | 2008 | 18572122 |
| receptor webs: can the chunking theory tell us more about it? | fundamental concepts shared by several classes of ionotropic and metabotropic cell surface receptors, such as receptor mosaic, cooperation, clustering, propensity to oligomerize, all finding expression in the dynamically structured mosaic membrane, will be revisited here in the light of the "combinatorial receptor web model" and the unifying information-processing mechanism defined as "chunking theory". particularly the ubiquitous and phylogenetically most ancient p2 receptors for extracellular ... | 2008 | 18597852 |

| the role of meaning in contextual cueing: evidence from chess expertise. | in contextual cueing, the position of a search target is learned over repeated exposures to a visual display. the strength of this effect varies across stimulus types. for example, real-world scene contexts give rise to larger search benefits than contexts composed of letters or shapes. we investigated whether such differences in learning can be at least partially explained by the degree of semantic meaning associated with a context independently of the nature of the visual information available ... | 2008 | 18609364 |
| quantum private queries. | we propose a cheat sensitive quantum protocol to perform a private search on a classical database which is efficient in terms of communication complexity. it allows a user to retrieve an item from the database provider without revealing which item he or she retrieved: if the provider tries to obtain information on the query, the person querying the database can find it out. the protocol ensures also perfect data privacy of the database: the information that the user can retrieve in a single quer ... | 2008 | 18643478 |
| a paradoxical signal intensity increase in fatty livers using opposed-phase gradient echo imaging with fat-suppression pulses. | with the increase in obese and overweight children, nonalcoholic fatty liver disease has become more prevalent in the pediatric population. appreciating subtleties of magnetic resonance (mr) signal intensity behavior from fatty livers under different imaging conditions thus becomes important to pediatric radiologists. we report an initially confusing signal behavior-increased signal from fatty livers when fat-suppression pulses are applied in an opposed-phase gradient echo imaging sequence-and s ... | 2008 | 18677467 |
| nicolae c. paulescu--scientist and politician. | the question of who discovered insulin is controversial. one of the scientists working on pancreas extracts was nicolae paulescu, the so-called forgotten man. in addition to his scientific research he was also active in politics. he was the father of the virulent antisemitic fascist movement "garda de fer" in romania; he raved against the "jewish peril," claimed in his writings that the jews are a genetically degenerate people trying to cheat and poison the rumanian people by alcoholism, and mor ... | 2008 | 18751624 |
| deliberate practice and acquisition of expert performance: a general overview. | traditionally, professional expertise has been judged by length of experience, reputation, and perceived mastery of knowledge and skill. unfortunately, recent research demonstrates only a weak relationship between these indicators of expertise and actual, observed performance. in fact, observed performance does not necessarily correlate with greater professional experience. expert performance can, however, be traced to active engagement in deliberate practice (dp), where training (often designed ... | 2008 | 18778378 |

| honesty and heroes: a positive psychology view of heroism and academic honesty. | academic honesty is under-researched in contrast to academic dishonesty. a majority of students self-report cheating in college. a low probability of punishment is reflected by few tried cases of academic misconduct. the authors argue that students who are in the minority by not engaging in academic dishonesty show considerable character strength and are examples of everyday heroes. the authors consider heroes persons who are courageous, have empathic concern for others, and have a high degree o ... | 2008 | 18792648 |
| context-dependent behavior and the benefits of communal nesting. | we present a model for the behavior of communally nesting insects. females may forage for food to provision offspring or may remain in the nest, with the option of eating and replacing nest mates' eggs. orphaned brood are at risk of predation. the optimal behavior of solitary females is determined using stochastic dynamic programming; static and dynamic evolutionarily stable strategies (esss) are then calculated for colonies of various sizes. a solitary female should forage if her brood is small ... | 1998 | 18811389 |
| reproducible mri measurement of adipose tissue volumes in genetic and dietary rodent obesity models. | to develop ratio mri [lipid/(lipid+water)] methods for assessing lipid depots and compare measurement variability with biological differences among lean controls (spontaneously hypertensive rats [shrs]), dietary obese rats (shr-dos), and genetic/dietary obese rats (shrobs). | 2008 | 18821617 |
| [nutritional habits of young chess players]. | proper nutrition plays significant role in children's development and health protection in adults, as well. therefore such a study is extremely important particularly among youth population. it is well known that adequate nutrition also helps to achieve high sport results. the aim of the study was the nutritional habits evaluation of young chess players. | 2008 | 18922226 |
| pairs of cooperating cleaner fish provide better service quality than singletons. | service providers may vary service quality depending on whether they work alone or provide the service simultaneously with a partner. the latter case resembles a prisoner's dilemma, in which one provider may try to reap the benefits of the interaction without providing the service. here we present a game-theory model based on the marginal value theorem, which predicts that as long as the client determines the duration, and the providers cooperate towards mutual gain, service quality will increas ... | 2008 | 18923522 |
| effect of expertise acquisition on strategic perception: the example of chess. | the two experiments presented here study perceptual processes implemented by chess players in situations related to their domain of expertise. the aim was to determine how patterns are perceived as a function of their strategic value when players acquire expertise. in this study, conducted on novice and more experienced players, it is hypothesized that with acquisition of expertise players would quickly encode familiar patterns and then rapidly focus their attention on patterns with a higher imm ... | 2008 | 18938781 |
| the prevalence of academic dishonesty in texas dental hygiene programs. | the media has given much attention to the academic cheating crisis in america. a majority of college students believe that, in today's global environment, it is necessary to cheat in order to get ahead and to compete with their peers. the prevalence and attitudes concerning academic dishonesty of health professions students, including those in medical, dental, and nursing schools, have been extensively researched. no such studies exist in the discipline of dental hygiene. the purpose of this stu ... | 2008 | 18981203 |
| striatum and pre-sma facilitate decision-making under time pressure. | human decision-making almost always takes place under time pressure. when people are engaged in activities such as shopping, driving, or playing chess, they have to continually balance the demands for fast decisions against the demands for accurate decisions. in the cognitive sciences, this balance is thought to be modulated by a response threshold, the neural substrate of which is currently subject to speculation. in a speed decision-making experiment, we presented participants with cues that i ... | 2008 | 18981414 |
| the stress of chess players as a model to study the effects of psychological stimuli on physiological responses: an example of substrate oxidation and heart rate variability in man. | we have studied the physiological consequences of the tension caused by playing chess in 20 male chess players, by following heart rate, heart rate variability, and respiratory variables. we observed significant increase in the heart rate (75-86 beats/min), in the ratio low frequency (lf)/high frequency (hf) of heart rate variability (1.3-3.0) and also a decrease in mean heart rate variability with no changes in hf throughout the game. these results suggest a stimulation of the sympathetic nervo ... | 2009 | 18987876 |

| erbb antagonists patenting: "playing chess with cancer". | erbbs signalling is always associated with the development of the majority of solid cancers via both the mapk pathway leading to cell cycle progression and the pi3k pathway causing cell survival. as a consequence, many erbb antagonists have been developed and patented for cancer treatment purposes. these antagonists belong to two drug classes: monoclonal antibodies (mabs) and small molecules competing with atp and inhibiting the tyrosine kinase domain (tkis). three patented mabs are currently ap ... | 2008 | 19075865 |
| the chess method of forensic opinion formulation: striving to checkmate bias. | expert witnesses use various methods to render dispassionate opinions. some forensic psychiatrists acknowledge bias up front; other experts use principles endorsed by the american academy of psychiatry and the law or other professional organizations. this article introduces chess, a systematic method for reducing bias in expert opinions. the chess method involves identifying a claim or preliminary opinion; developing a hierarchy of supporting evidence; examining the evidence for weaknesses or ar ... | 2008 | 19092072 |
| why are (the best) women so good at chess? participation rates and gender differences in intellectual domains. | a popular explanation for the small number of women at the top level of intellectually demanding activities from chess to science appeals to biological differences in the intellectual abilities of men and women. an alternative explanation is that the extreme values in a large sample are likely to be greater than those in a small one. although the performance of the 100 best german male chess players is better than that of the 100 best german women, we show that 96 per cent of the observed differ ... | 2009 | 19129102 |
| direct c-h metalation with chromium(ii) and iron(ii): transition-metal host/benzenediide guest magnetic inverse-crown complexes. | check m(etal)ate: the chessboard and the figures represent a special reaction in which different low-polarity metals can metalate arenes directly when they are brought into the right position. in a combination of queen (sodium) and knight (chromium or iron), it is possible for the knight (usually the weaker piece) to make a direct deadly hit on the king (benzene) in this game of elemental chess. | 2009 | 19156782 |
| how are traits related to problem behavior in preschoolers? similarities and contrasts between temperament and personality. | the lack of empirical research relating temperament models and personality hinders conceptual integration and holds back research linking childhood traits to problem behavior or maladjustment. this study evaluates, within a sample of 443 preschoolers, the relationships between children's maladaptation and traits measured by three temperament models (thomas and chess, buss and plomin, and rothbart), and a five-factor based personality model. adequate reliabilities and expected factor structures a ... | 2009 | 19165590 |
| 'i want to lose weight': early risk for disordered eating? | the present study examined the risk of disordered eating and its relation to attempts to lose weight by surveying a maritime canadian sample of 247 girls and boys in grades 6, 7 and 8. current attempts to lose weight were highest in grade 8 girls (41% of girls and 9% of boys) compared with grade 6 (14% of girls and 24% of boys) and grade 7 (21% of girls and 13% of boys) children. of those trying to lose weight, 71.4% were in the average range for weight and height, 12.2% were overweight and 16.3 ... | 2008 | 19183713 |
| queen ants make distinctive sounds that are mimicked by a butterfly social parasite. | ants dominate terrestrial ecosystems through living in complex societies whose organization is maintained via sophisticated communication systems. the role of acoustics in information exchange may be underestimated. we show that myrmica schencki queens generate distinctive sounds that elicit increased benevolent responses from workers, reinforcing their supreme social status. although fiercely defended by workers, ant societies are infiltrated by specialist insects that exploit their resources. ... | 2009 | 19197065 |
| playing chess unconsciously. | expertise in a certain stimulus domain enhances perceptual capabilities. in the present article, the authors investigate whether expertise improves perceptual processing to an extent that allows complex visual stimuli to bias behavior unconsciously. expert chess players judged whether a target chess configuration entailed a checking configuration. these displays were preceded by masked prime configurations that either represented a checking or a nonchecking configuration. chess experts, but not ... | 2009 | 19210101 |
| survival prediction in nursing home residents using the minimum data set subscales: adl self-performance hierarchy, cognitive performance and the changes in health, end-stage disease and symptoms and signs scales. | with the intention to aid planning for elderly focused public health and residential care needs in rapidly aging societies, a simple model using only age, gender and three minimum data set (mds) subscales (mds-adl self-performance hierarchy, mds-cognitive performance and the mds-changes in health, end-stage disease and symptoms and signs scales) was used to estimate long-term survival of older people moving into nursing homes. | 2009 | 19221020 |
| individual differences in expertise development over decades in a complex intellectual domain. | learners acquire expertise at different rates and reach different peak performance levels. key questions arise regarding what patterns of individual differences in expertise development occur and whether innate talent affects such development. international chess is a good test domain for both issues, because it has objective performance measures, actual practice measures (number of games), longitudinal population data, and minimal gatekeeper influence. players' expertise development typically f ... | 2009 | 19223569 |

| when will evolution lead to deceptive signaling in the sir philip sidney game? | sir philip sidney games are a widely used model of simple signaling. johnstone and grafen [johnstone, r.a., grafen, a., 1993. dishonesty and the handicap principle. animal behaviour 46, 759-764] present a version in which the evolutionarily stable strategy (ess) is for most signalers to "honestly" signal, with a small minority of signalers who "cheat". this model is among the most frequently cited papers on the topic of "dishonest" signaling and supports the view that signals may be "dishonest" ... | 2010 | 19268678 |
| the heritability of aptitude and exceptional talent across different domains in adolescents and young adults. | the origin of individual differences in aptitude, defined as a domain-specific skill within the normal ability range, and talent, defined as a domain specific skill of exceptional quality, is under debate. the nature of the variation in aptitudes and exceptional talents across different domains was investigated in a population based twin sample. self-report data from 1,685 twin pairs (12-24 years) were analyzed for music, arts, writing, language, chess, mathematics, sports, memory, and knowledge ... | 2009 | 19288254 |
| the effects of nanoparticles uptaken by cells on electrorotation. | electrorotation (er) has become a very powerful diagnostic technique for the measurement of dielectric properties of cells. however, only a few papers have investigated the electric-induced rotation of particles in a stationary alternating (ac) electric field instead of a rotating electric field. in this study, a microchip composed of a top-grounded electrode, flow chamber and bottom chess-type electrode arrays was used to construct a stationary non-uniform ac electric field for the manipulation ... | 2009 | 19350546 |

| [a clinical, health, economic and satisfaction simulation model, chess: a tool for healthcare organization management]. | the management of medical organizations is based on a profound understanding of the essence of the organization, its vision and missions, as well as the methods the organization utilizes to gather and analyze information. in order to maintain a maximal function level in an ever-changing environment, all organization components must function in tandem. in a previous article the authors presented medical organizations as macro systems composed of micro systems, and discussed the challenges these o ... | 2009 | 19485280 |
| comparison of diffusion-weighted images using short inversion time inversion recovery or chemical shift selective pulse as fat suppression in patients with breast cancer. | fat suppression is essential for diffusion-weighted imaging (dwi) in the body. however, the chemical shift selective (chess) pulse often fails to suppress fat signals in the breast. the purpose of this study was to compare dwi using chess and dwi using short inversion time inversion recovery (stir) in terms of fat suppression and the apparent diffusion coefficient (adc) value. | 2009 | 19499306 |
| potential benefits of recombinant human growth hormone (rhgh) to athletes. | athletes have enjoyed almost a thirty year amnesty of rhgh abuse, which they consider has contributed to the winning of medals and the breaking of world records. such a reprieve is almost at an end, since wada have identified a method to detect rhgh abuse. or have they? the anecdotal word "on the street" is that rhgh is still undetectable and athletes believe that the benefits, at the dosages they administer, far outweigh the risks! scientists are aware that in a hormone deficiency condition, re ... | 2009 | 19539505 |
| adsorption and pinning of multiblock copolymers on chemically heterogeneous patterned surfaces. | the results of monte carlo simulations carried out on a system of multiblock copolymers having two different types of monomer units adsorbed on checker board surface configurations are presented here. we investigated the adsorption behavior for a series of different chess board square dimensions and also for various block lengths of the copolymer. we find that the specific heat capacity curves for adsorption indicate double peaks showing a two stage pattern recognition of the copolymer on the su ... | 2009 | 19548750 |
| non-contrast-enhanced hepatic mr angiography: do two-dimensional parallel imaging and short tau inversion recovery methods shorten acquisition time without image quality deterioration? | to study whether shortening the acquisition time for selective hepatic artery visualization is feasible without image quality deterioration by adopting two-dimensional (2d) parallel imaging (pi) and short tau inversion recovery (stir) methods. | 2011 | 19556088 |
| genetic enhancements and expectations. | some argue that genetic enhancements and environmental enhancements are not importantly different: environmental enhancements such as private schools and chess lessons are simply the old-school way to have a designer baby. i argue that there is an important distinction between the two practices--a distinction that makes state restrictions on genetic enhancements more justifiable than state restrictions on environmental enhancements. the difference is that parents have no settled expectations abo ... | 2009 | 19567693 |
| metal ion chelate-assisted ligation (chess liga) for snp detection on microarrays. | we developed a metal ion chelate-assisted ligation for snp detection by microarray. an oligonucleotide probe was separated into two 9-10-mers bearing iminodiacetic residues at the gap point. duplex formation with the dna target was possible only if nickel ions were added, but a nucleotide substitution opposite the gap point prevented duplex formation. here we demonstrate the application of this approach for snp detection (a1298c) within the 5,10-methylenetetrahydrofolate reductase gene on a micr ... | 2009 | 19574044 |
| implicit and explicit attitude dissociation in spontaneous deceptive behavior. | society considers deception to be an improper act but at the same time, people deceive each other surprisingly often during interpersonal interactions. in our study, this hypocrisy was assumed to be derived from ambivalent attitudes stemming from different sources, which we divided into implicit and explicit. using a simulated racing task in a virtual environment, we identified participants who chose to be deceptive. twenty two of the 60 subjects spontaneously decided to cheat in order to gain m ... | 2009 | 19577223 |

| the interpretation of clinical trial data--wrongly acclaim'ed? | advances in medicine continue to drive forward through the practice of often impressive and innovative investigation. through the application of randomized clinical trials, statistical analyses deliver the notorious "p values" to provide evidence of whether an intervention results in the desired clinical effect. however, it would appear that it is becoming increasingly common for trial reports to "cheat" the statistical system, particularly when lucrative industrial reward might be at stake. for ... | 2009 | 19619687 |
| [acceptance and commitment therapy (act) and improving chess performance in promising young chess-players]. | acceptance and commitment therapy (act) is shown to be effective in relatively distant fields from the so-called psychological disorders. one of these areas is sport performance improvement. the aim of the current study is to expand the application of brief act protocols to improve chess-players' performance. in a previous study, a brief protocol was applied to international-level adult chess-players that was effective. the current study aims to apply an equivalent brief act protocol, but in thi ... | 2009 | 19622312 |
| are all types of morality compromised in psychopathy? | a long-standing puzzle for moral philosophers and psychologists alike is the concept of psychopathy, a personality disorder marked by tendencies to defy moral norms despite cognitive knowledge about right and wrong. previously, discussions of the moral deficits of psychopathy have focused on willingness to harm and cheat others as well as reasoning about rule-based transgressions. yet recent research in moral psychology has begun to more clearly define the domains of morality, encompassing issue ... | 2009 | 19663658 |
| evaluation of dystrophic dog pathology by fat-suppressed t2-weighted imaging. | duchenne muscular dystrophy (dmd) is a devastating muscle disorder that is characterized by progressive muscle necrosis, fibrosis, and fatty infiltration. to examine the temporospatial pathological changes, a noninvasive evaluation method such as magnetic resonance imaging (mri) is needed. the aim of this study was to precisely assess muscle necrosis and inflammation based on a sequence of t2-weighted imaging (t2wi), gadolinium-enhanced imaging, and selective fat suppression, chemical shift sele ... | 2009 | 19670324 |

| a multimodal interface device for online board games designed for sight-impaired people. | online games between remote opponents playing over computer networks are becoming a common activity of everyday life. however, computer interfaces for board games are usually based on the visual channel. for example, they require players to check their moves on a video display and interact by using pointing devices such as a mouse. hence, they are not suitable for visually impaired people. the present paper discusses a multipurpose system that allows especially blind and deafblind people playing ... | 2010 | 19858031 |
| scherrer grain-size analysis adapted to grazing-incidence scattering with area detectors. | ever since its formulation, the scherrer formula has been the workhorse for quantifying finite size effects in x-ray scattering. various aspects of scherrer-type grain-size analysis are discussed with regard to the characterization of thin films with grazing-incidence scattering methods utilizing area detectors. after a brief review of the basic features of scherrer analysis, a description of resolution-limiting factors in grazing-incidence scattering geometry is provided. as an application, the ... | 2009 | 19953189 |
| development of a health-related website for parents of children receiving hematopoietic stem cell transplant: hsct-chess. | parents of pediatric hematopoietic stem cell transplant (hsct) play a pivotal role in the care of their child during and after transplant. in addition to the child's comforter, parents also serve as care coordinators and conduits of communication between various health care providers, family and community members. the stress on the parent and family is enormous during this process, which for many is compounded by geographic dislocation to accompany their child during the rigorous treatment and r ... | 2010 | 19967409 |

| chess (cghexpress): a comprehensive analysis tool for the analysis of genomic alterations and their effects on the expression profile of the genome. | genomic alterations frequently occur in many cancer patients and play important mechanistic roles in the pathogenesis of cancer. furthermore, they can modify the expression level of genes due to altered copy number in the corresponding region of the chromosome. an accumulating body of evidence supports the possibility that strong genome-wide correlation exists between dna content and gene expression. therefore, more comprehensive analysis is needed to quantify the relationship between genomic al ... | 2009 | 20003544 |
| too tired to tell the truth: self-control resource depletion and dishonesty. | the opportunity to profit from dishonesty evokes a motivational conflict between the temptation to cheat for selfish gain and the desire to act in a socially appropriate manner. honesty may depend on self-control given that self-control is the capacity that enables people to override antisocial selfish responses in favor of socially desirable responses. two experiments tested the hypothesis that dishonesty would increase when people's self-control resources were depleted by an initial act of sel ... | 2009 | 20047023 |
| clean olympians? doping and anti-doping: the views of talented young british athletes. | review articles suggest a small but significant proportion (between 3 and 12%) of male adolescents have used anabolic-androgenic steroids (aas) at some point (yesalis and bahrke, 2000; calfee and fadale, 2006). in sport, the use of prohibited substances or processes to enhance performance, collectively referred to as 'doping', is banned by both sports' national and international governing bodies, and by the world anti-doping agency (wada) who run an extensive testing programme and educational in ... | 2010 | 20056401 |
| feasibility of one-shot-per-crystal structure determination using laue diffraction. | crystal size is an important factor in determining the number of diffraction patterns which may be obtained from a protein crystal before severe radiation damage sets in. as crystal dimensions decrease this number is reduced, eventually falling to one, at which point a complete data set must be assembled using data from multiple crystals. when only a single exposure is to be collected from each crystal, the polychromatic laue technique may be preferable to monochromatic methods owing to its simu ... | 2010 | 20057043 |
| variable selection patterns on the labellum shape of geoblasta pennicillata, a sexually deceptive orchid. | by mimicking shape and female mating pheromones, flowers of sexually deceptive orchids attract sexually excited males which pollinate them while trying to copulate. although many studies have demonstrated the crucial importance of odour signals in these systems, most flowers pollinated by pseudocopulation resemble, at least superficially, an insect body and these visual cues may be important to cheat pollinators. in this 2-year study, we show that the shape of the labellum of geoblasta pennicill ... | 2009 | 20069726 |
