| quantum protocol for cheat-sensitive weak coin flipping. | we present a quantum protocol for the task of weak coin flipping. we find that, for one choice of parameters in the protocol, the maximum probability of a dishonest party winning the coin flip if the other party is honest is 1/sqrt[2]. we also show that if parties restrict themselves to strategies wherein they cannot be caught cheating, their maximum probability of winning can be even smaller. as such, the protocol offers additional security in the form of cheat sensitivity. | 2002 | 12485105 |
| visuospatial abilities of chess players. | the extent to which the acquisition of expertise in knowledge-rich domains, such as chess, can be influenced by general individual characteristics, such as intelligence, has remained unclear. some previous studies with children have documented significant correlations between chess skill and performance on some psychometric tests, such as performance iq. however, we found no evidence for a correlation between chess skill and visual memory ability in a group of adult chess players (n = 36, age = ... | 2002 | 12519534 |
| [evaluation of t(1)-weighted black blood imaging using triple inversion recovery]. | the black blood sequence, in which the blood signal is suppressed, fundamentally provides t(2)-weighted images. we developed a t(1)-weighted black blood sequence. this new sequence improved the triple ir sequence that uses three inversion pulses by continuously providing three inversion pulses. by so doing, the sequence lengthens the time from the third inversion pulse to data sampling. the new sequence sets the flip angle of the third inversion pulse to 95-110 degrees. consequently, the differe ... | 2002 | 12520219 |

| electronic support groups for breast carcinoma: a clinical trial of effectiveness. | a recent pew charitable trust study found that 52,000,000 individuals used the internet to obtain health/medical information. clinical trials of face-to-face breast carcinoma support groups show evidence of 1) improvement in quality of life, 2) reduction of psychologic symptoms, 3) improvement in coping responses, and 4) a reduction in pain. to the authors' knowledge, a few studies published to date have investigated internet-delivered electronic support groups (esgs) for cancer. the most sophis ... | 2003 | 12569591 |
| the functional localization of neural networks using genetic algorithms. | we presented an algorithm for extracting boolean functions (propositions, rules) from the units in trained neural networks. the extracted boolean functions make the hidden units understandable. however, in some cases, the extracted boolean functions are complicated, and so are not understandable, which means that the hidden units are not functionally localized. this paper presents an algorithm for the functional localization of (the hidden units of) neural networks. when a hidden unit is well ap ... | 2003 | 12576106 |
| a functional mri study of high-level cognition. i. the game of chess. | chess is a game that involves many aspects of high level cognition and requires sophisticated problem solving skills. however, there is little understanding of the neural basis of chess cognition. this study employed functional magnetic resonance imaging (fmri) to identify cortical areas that are active during the analysis of chess positions compared with a spatial task with matched visual stimuli. bilateral activation was revealed in the superior frontal lobes, the parietal lobes, and occipital ... | 2003 | 12589885 |
| a functional mri study of high-level cognition. ii. the game of go. | go is a board game thought to be different from chess in many aspects, most significantly in that go emphasizes global strategy more than local battle, a property very difficult for computer programs to emulate. to investigate the neural basis of go, functional magnetic resonance imaging (fmri) was used to measure brain activities of subjects engaged in playing go. enhanced activations were observed in many cortical areas, such as dorsal prefrontal, parietal, occipital, posterior temporal, and p ... | 2003 | 12589886 |
| common language or tower of babel? on the evolutionary dynamics of signals and their meanings. | we investigate how the evolution of communication strategies affects signal credibility when there is common interest as well as a conflict between communicating individuals. taking alarm calls as an example, we show that if the temptation to cheat is low, a single signal is used in the population. if the temptation increases cheaters will erode the credibility of a signal, and an honest mutant using a different signal ('a private code') will be very successful until this, in turn, is cracked by ... | 2003 | 12590773 |
| comparison of assessments of children's eating-disordered behaviors by interview and questionnaire. | in adults, interview methods may detect eating-disordered behaviors more accurately than self-report methods. however, no studies have investigated the relationships between interview and self-report assessments in children. we compared results from the eating disorder examination adapted for children (chede) with the adolescent version of the questionnaire on eating and weight patterns (qewp-a) and with the children's eating attitude test (cheat) in a nontreatment sample of overweight and norma ... | 2003 | 12616588 |

| global gamesmanship. | competition among multinationals these days is likely to be a three-dimensional game of global chess: the moves an organization makes in one market are designed to achieve goals in another in ways that aren't immediately apparent to its rivals. the authors--all management professors-call this approach "competing under strategic interdependence," or csi. and where this interdependence exists, the complexity of the situation can quickly overwhelm ordinary analysis. indeed, most business strategist ... | 2003 | 12747163 |
| [temperament and affective disorders--historical basis of current discussion]. | the history of the temperament concept begins in ancient greece. the humoral theory remained influential over the centuries. at the beginning of the 20 th century, both wilhelm wundt and his pupil emil kraepelin formulated new aspects. wundt described two dimensions: "speed of variability of emotions" and "intensity of emotions". kraepelin observed four fundamental states (depressive, manic, irritable and cyclothymic), which he linked to manic-depressive illness. since then different lines of te ... | 2003 | 12796852 |

| crystallization and preliminary crystallographic analysis of a new class of glutathione transferase from nematodes. | mouse and heligmosomoides polygyrus constitute a readily manipulated small-animal laboratory model for investigating host-nematode interactions. two major forms of glutathione transferase (gst) are expressed in h. polygyrus adult worms following primary infection. one of these forms belongs to a new class of gst which has only been found in the nematode phylum and therefore presents a possible target for nematode control. in this study, crystals were obtained of a recombinant representative of t ... | 2003 | 12832779 |
| nectarless flowers: ecological correlates and evolutionary stability. | in animal-pollinated flowers, the pollinators cannot detect the presence of nectar before entering flowers, and therefore flowers may cheat by not producing nectar. an earlier model suggested that a mixed strategy of producing nectarful and nectarless flowers would be evolutionarily stable. here we compare nectarless flowers as a cheating strategy with three competing hypotheses namely "visit-more-flowers", "cross-pollination enhancement" and "better contact". we collected field data on 28 speci ... | 2003 | 12838401 |

| adolescence and the diet-dieting disparity: healthy food choice or risky health behaviour? | food choice in schoolchildren was examined in relation to dieting and measures of eating psychopathology. it was predicted that dieters would make healthier food choices compared to non-dieters and that measures of eating psychopathology would be associated with food choice. | 2003 | 14614792 |
| the role of constraints in expert memory. | a great deal of research has been devoted to developing process models of expert memory. however, k. j. vicente and j. h. wang (1998) proposed (a) that process theories do not provide an adequate account of expert recall in domains in which memory recall is a contrived task and (b) that a product theory, the constraint attunement hypothesis (cah), has received a significant amount of empirical support. we compared 1 process theory (the template theory; tt; f. gobet & h. a. simon, 1996c) with the ... | 2003 | 14622048 |

| judgment and decision-making: experts' and novices' evaluation of chess positions. | the present study examined how experts differ from nonexperts in estimation and evaluation during a judgment-and-decision task. in the experiment, the performance of 125 chess players (21 women and 104 men) whose mean age was 32.5 yr. (sd = 13.3) was examined to assess decision processes with an emphasis on postdecision differentiation and consolidation. chess players of differing skill made evaluations of a complex middle-game chess position. the experimental condition was made by the means of ... | 2004 | 15058886 |
| the prisoner's dilemma and polymorphism in yeast suc genes. | the suc multigene family of the single-celled yeast saccharomyces cerevisiae is polymorphic, with genes varying both in number and activity. all of the genes encode invertase, an enzyme that is secreted to digest sucrose outside of the cell. this communal endeavour creates the potential for individual cells to defect (cheat) by stealing the sugar digested by their neighbours without contributing the enzyme themselves. we measured the fitness of a defector, with a deleted suc2 gene, relative to a ... | 2004 | 15101409 |
| dieting among preadolescent and young adolescent females. | we examined the prevalence of dieting and negative eating attitudes among 2279 females (aged 10-14 years) in southern ontario. self-report questionnaires revealed that 29.3% of the girls were currently trying to lose weight and 10.5% had scores greater than the clinical threshold for disordered eating (children's version of the eating attitudes test [cheat] score > or = 20). those with elevated cheat scores were more likely than those with lower scores to be engaged in dieting and other extreme ... | 2004 | 15136549 |

| bromus species in winter wheat-population dynamics and competitiveness. | the infestation of bromus species in small grains, especially in winter cereals has increased over recent years. in some areas winter wheat growers consider bromus spp. as their worst grass weed. besides yield reduction, bromus spp. cause lodging and complication of harvest. in germany the two most dominant species are bromus sterilis (l.) and bromus secalinus (l.). in order to develop control strategies the population dynamics of the weeds were investigated. based on the results a deterministic ... | 2003 | 15149129 |
| does academic dishonesty relate to unethical behavior in professional practice? an exploratory study. | previous research indicates that students in engineering self-report cheating in college at higher rates than those in most other disciplines. prior work also suggests that participation in one deviant behavior is a reasonable predictor of future deviant behavior. this combination of factors leads to a situation where engineering students who frequently participate in academic dishonesty are more likely to make unethical decisions in professional practice. to investigate this scenario, we propos ... | 2004 | 15152857 |
| cheat sensitive quantum bit commitment. | we define cheat sensitive cryptographic protocols between mistrustful parties as protocols which guarantee that, if either cheats, the other has some nonzero probability of detecting the cheating. we describe an unconditionally secure cheat sensitive nonrelativistic bit commitment protocol which uses quantum information to implement a task which is classically impossible; we also describe a simple relativistic protocol. | 2004 | 15169319 |
| the effects of speed on skilled chess performance. | two types of mechanisms may underlie chess skill: fast mechanisms, such as recognition, and slow mechanisms, such as search through the space of possible moves and responses. speed distinguishes these mechanisms, so i examined archival data on blitz chess (5 min for the whole game), in which the opportunities for search are greatly reduced. if variation in fast processes accounts for substantial variation in chess skill, performance in blitz chess should correlate highly with a player's overall ... | 2004 | 15200627 |
| common sense, intuition, and theory in personality and social psychology. | theoretical work in personality and social psychology benefits from a well-developed understanding of the prior empirical and theoretical work on a problem and from informed intuitions. intuitions develop about a subject matter through years of study, investigation, and problem solving, just as chess masters develop a sophisticated set of cognitive structures that change the very appearance of the chess board. in part because the subject matter is so personal, students new to personality and soc ... | 2004 | 15223510 |
| protein crystallography using a multilayer monochromator. | a multilayer monochromator was installed on a bending-magnet beamline at the cornell high energy synchrotron source (chess) and was used to provide an unfocused pseudo-monochromatic x-ray beam for protein crystallography experiments. datasets were collected from lysozyme at room temperature and human methylthioadenosine phosphorylase at 100 k. the wide energy bandpass of the multilayer allowed short exposure times, typically only a few times longer than on a focused multipole wiggler beamline. t ... | 1998 | 15263556 |

| evolution of spite through indirect reciprocity. | how can cooperation persist in the face of a temptation to 'cheat'? several recent papers have suggested that the answer may lie in indirect reciprocity. altruistic individuals may benefit by eliciting altruism from observers, rather than (as in direct reciprocity) from the recipient of the aid they provide. here, we point out that indirect reciprocity need not always favour cooperation; by contrast, it may support spiteful behaviour, which is costly for the both actor and recipient. existing th ... | 2004 | 15347514 |

| pleiotropy as a mechanism to stabilize cooperation. | most genes affect many traits. this phenomenon, known as pleiotropy, is a major constraint on evolution because adaptive change in one trait may be prevented because it would compromise other traits affected by the same genes. here we show that pleiotropy can have an unexpected effect and benefit one of the most enigmatic of adaptations--cooperation. a spectacular act of cooperation occurs in the social amoeba dictyostelium discoideum, in which some cells die to form a stalk that holds the other ... | 2004 | 15470429 |
| child temperament does not predict adolescent body composition in girls. | our previous cross-sectional analysis of mit growth and development (mit) study girls showed that activity temperament, as assessed by a nine-item temperament questionnaire, was related to body composition and nonresting energy expenditure (nree). in girls with lower levels of physical activity, having a high activity temperament was associated with a higher nree. percentage body fat was lower in girls with high vs low activity temperament. based on these results, we hypothesized that, especiall ... | 2005 | 15545977 |

| chess-playing epilepsy: a case report with video-eeg and back averaging. | a patient suffering from juvenile myoclonic epilepsy experienced myoclonic jerks, fairly regularly, while playing chess. the myoclonus appeared particularly when he had to plan his strategy, to choose between two solutions or while raising the arm to move a chess figure. video-eeg-polygraphy was performed, with back averaging of the myoclonus registered during a chess match and during neuropsychological testing with kohs cubes. the eeg spike wave complexes were localised in the fronto-central re ... | 2004 | 15634627 |
| allelic dimorphism in the merozoite surface protein-3alpha in korean isolates of plasmodium vivax. | to study the genetic diversity of re-emerging plasmodium vivax in the republic of korea, nucleotide sequence variations at the merozoite surface protein-3alpha (pvmsp-3alpha) locus were analyzed using 24 re-emerging isolates and 4 isolates from imported cases. compared with the well known belem strain (brazil), a large number of amino acid substitutions, deletions, and insertions were found at the locus of the isolates examined. the korean isolates were divided into two allelic types; type i (15 ... | 2004 | 15642964 |
| the clinical health economics system simulation (chess): a teaching tool for systems- and practice-based learning. | academic medical centers face barriers to training physicians in systems- and practice-based learning competencies needed to function in the changing health care environment. to address these problems, at the university of virginia school of medicine the authors developed the clinical health economics system simulation (chess), a computerized team-based quasi-competitive simulator to teach the principles and practical application of health economics. chess simulates treatment costs to patients a ... | 2005 | 15671315 |
| enhancing ethical behavior: views of students, administrators, and faculty. | in an article published in the april 2004 issue of the journal of dental education, dr. charles bertolami proposed that our ethics curricula don't work due to the limitations of didactic education. he suggested that ethics should be taught as a "precurriculum" course prior to entering dental school and that the dental school ethics course should be elective and consist of small groups of students who are guided to introspection to understand their true self-interest. he argued that "enlightened" ... | 2005 | 15689604 |
| [effect of sport participation on the dynamics of attention parameters and successfulness of studies in school children of junior age]. | the study of dynamics of attention parameters in junior schoolchildren (aged from 7 to 9) going in for sports has established that this period of ontogenesis is characterized by further progressive development of attention, though uneven in rate. the age-related dynamics of change in attention parameters (its volume, efficiency, distribution and turning rate) in children having additional physical and intellectual load has been discovered to be identical with non-sportive group. the rate of form ... | 2004 | 15693302 |
| adulteration of foodstuffs: from misleading to poisoning. experiences of a new eu member state (hungary) on the threshold of market economy. | the increasing number of food producers, and the outstanding amount of import foodstuffs enables the producers to mislead and cheat consumers. to differentiate those who take advantage of legal rules from the ones who commit food adulteration is very difficult. the consciousness of consumers would be crucial. however, how can we expect consequent behavior from them regarding controversial issues emerging day by day? in addition, ignorance and unfair market behavior may endanger consumer health a ... | 2005 | 15702595 |

| chunks in expert memory: evidence for the magical number four ... or is it two? | this study aims to test the divergent predictions of the chunking theory (chase & simon, 1973) and template theory (gobet & simon, 1996a, 2000) with respect to the number of chunks held in visual short-term memory and the size of chunks used by experts. we presented game and random chessboards in both a copy and a recall task. in a within-subject design, the stimuli were displayed using two presentation media: (a) physical board and pieces, as in chase and simon's (1973) study; and (b) a compute ... | 2004 | 15724362 |
| computer-aided organic synthesis. | it is tempting for those in the field of organic synthesis to liken the process of retrosynthesis to a game of chess. that the world chess champion was recently defeated by a computer leads us to think that perhaps new and powerful computing methods could be applied to synthetic problems. here the analogy between synthesis and chess is outlined. achievements in the 35-year history of computer-aided synthetic design are described, followed by some more recent developments. | 2005 | 15726161 |

| knight's move thinking? mild cognitive impairment in a chess player. | we report the case of a chess player with superior premorbid cognitive function who presented to the cognitive disorders clinic at the national hospital for neurology and neurosurgery with a 2-year history of symptoms of possible memory loss. initially the mri scan appearance was within normal limits and his cognitive scores inside the normal range; subsequently his cognitive function deteriorated and he fulfilled criteria for mild cognitive impairment (mci) two years later. unexpectedly he died ... | 2005 | 15804921 |
| strategic intensity: a conversation with world chess champion garry kasparov. | it's hard to find a better exemplar for competition than chess. the image of two brilliant minds locked in a battle of skill and will-in which chance plays little or no apparent role-is compelling. even people who have scant knowledge of the game instinctively recognize that chess is unusual in terms of its intellectual complexity and the strategic demands it places on players. can strategists learn anything from chess players about what it takes to win? to find out, h br senior editor diane l. ... | 2005 | 15807038 |
| a psychometric analysis of chess expertise. | this study introduces the amsterdam chess test (act). the act measures chess playing proficiency through 5 tasks: a choose-a-move task (comprising two parallel tests), a motivation questionnaire, a predict-a-move task, a verbal knowledge questionnaire, and a recall task. the validity of these tasks was established using external criteria based on the elo chess rating system. results from a representative sample of active chess players showed that the act is a very reliable test for chess experti ... | 2005 | 15822609 |
