| 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 |

| counting channels: a tutorial guide on ion channel fluctuation analysis. | ion channels open and close in a stochastic fashion, following the laws of probability. however, distinct from tossing a coin or a die, the probability of finding the channel closed or open is not a fixed number but can be modified (i.e., we can cheat) by some external stimulus, such as the voltage. single-channel records can be obtained using the appropriate electrophysiological technique (e.g., patch clamp), and from these records the open probability and the channel conductance can be calcula ... | 2002 | 12444005 |
| chess: 10 years of research and development in consumer health informatics for broad populations, including the underserved. | this paper reviews the research and development around a consumer health informatics system chess (the comprehensive health enhancement support system) developed and tested by the center for health systems research and analysis at the university of wisconsin. the review places particular emphasis on what has been found with regard to the acceptance and use of such systems by high risk and underserved groups. | 2002 | 12414016 |
| too hot to handle? synchrotron x-ray damage of lipid membranes and mesophases. | the call for brighter synchrotron x-radiation sources for use in structural biology research is barely audible as we enter the new millennium. our brightest sources are already creating havoc when used at design specifications because of radiation damage. the time is long overdue to take stock of where we are and where we wish to go with regards to using existing sources and to designing new ones. the problem of radiation damage is particularly acute in studies involving kinetics and mechanisms ... | 2002 | 12409619 |
| biting cleaner fish use altruism to deceive image-scoring client reef fish. | humans are more likely to help those who they have observed helping others previously. individuals may thus benefit from being altruistic without direct reciprocity of recipients but due to gains in 'image' and associated indirect reciprocity. i suggest, however, that image-scoring individuals may be exploitable by cheaters if pay-offs vary between interactions. i illustrate this point with data on cleaner-client reef fish interactions. i show the following: (i) there is strong variation between ... | 2002 | 12396482 |

| epiparasitic plants specialized on arbuscular mycorrhizal fungi. | over 400 non-photosynthetic species from 10 families of vascular plants obtain their carbon from fungi and are thus defined as myco-heterotrophs. many of these plants are epiparasitic on green plants from which they obtain carbon by 'cheating' shared mycorrhizal fungi. epiparasitic plants examined to date depend on ectomycorrhizal fungi for carbon transfer and exhibit exceptional specificity for these fungi, but for most myco-heterotrophs neither the identity of the fungi nor the sources of thei ... | 2002 | 12353033 |
| the role of attack and defense semantics in skilled players' memory for chess positions. | there is much evidence that chess skill is based on chunks in memory that represent parts of positions from previously encountered games. however, the content of these chunks is a matter for debate. according to one view, (1) the closer two pieces are to each other on a board (proximity), the more likely they are to be in the same chunk, and (2) skilled players encode the precise locations of pieces. an alternative view is that what information is encoded in a chess chunk is determined more by p ... | 2002 | 12219888 |
| crystallization and preliminary crystallographic analysis of the ezrin ferm domain. | ezrin is a member of the erm (ezrin/radixin/moesin) family of proteins that cross-link the actin cytoskeleton to the plasma membrane and that also function, both upstream and downstream of the small g-protein rho, in signaling cascades that regulate the assembly of actin stress fibers. in this study, crystals were obtained of the amino-terminal 297 residues (referred to as ferm) of ezrin. the crystals of the ferm domain of ezrin belong to the monoclinic space group p2(1), with unit-cell paramete ... | 2002 | 12136155 |
| computational explorations of the influence of structured knowledge on age-related cognitive decline. | experience in a domain can sometimes offset cognitive declines that occur with aging. using a series of neural network simulations of learning chess opening positions, the authors investigated how structured knowledge in a distributed representation may influence age-related declines. aging manipulations implemented as modulations of neural noise showed increased knowledge as being protective of performance on a chess memory span task, whereas changes in neural plasticity and neural loss lead to ... | 2002 | 12061410 |
| increase in detrusor wall thickness indicates bladder outlet obstruction (boo) in men. | detrusor wall thickness decreases continuously while the bladder fills to 50% of its capacity and then remains constant until 100%. therefore, detrusor wall measurements were performed in patients when the bladder was filled to maximum capacity only. mean detrusor wall thickness for unobstructed (n = 14), equivocal (n=23) and obstructed patients (n=33) were 1.33, 1.62 and 2.4 mm, respectively (p <0.001). with increasing chess letters and chess numbers, the thickness of the detrusor wall increase ... | 2002 | 12022713 |

| cultural differences in use of an electronic discussion group. | this article describes how 121 women newly diagnosed with breast cancer used a computer mediated discussion group to cope with their diagnosis. these data are part of a larger data set from a randomized clinical trial assessing the impact of a computer-based system called chess (the comprehensive health enhancement support system) on health outcomes. the larger study found significant improvement in health outcomes for those in the experimental group (those receiving chess), especially for women ... | 2003 | 22113904 |
| introduction of the new analytical approaches to the doping control on the xiv winter olympic games. | in this paper we present introduction and development of some new analytical methods for identification of anabolic steroids, their metabolites and certain hormones, especially determination of exogenous testosterone by means of gas chromatography-mass spectrometry. identification of central nervous stimulants and corticosteroides has been performed by high performance liquid chromatography. in desire to achieve better results, to increase strength and endurance, to sharpen reflexes and to reduc ... | 2003 | 16232150 |
| 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 |

| 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 |
| 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 |
| selection of an adsorbent for lead removal from drinking water by a point-of-use treatment device. | the removal of lead from drinking water was investigated to develop a point-of-use water filter that could meet the regulation imposed by the new european directive 98-83 lowering lead concentration in drinking water below 10 microgl(-1). the objective of this research was to assess the potential of different adsorbents (zeolites, resins, activated carbon, manganese oxides, cellulose powder) to remove lead from tap water with a very short contact time. to begin, the repartition of the lead speci ... | 2003 | 14604636 |

| lie detection with contingent negative variation. | topographies of contingent negative variation (cnv) were recorded in a paradigm of delayed response with feedback for three kinds of faces: familiar, strange and target. subjects made responses to the faces according to whether the faces were familiar or not, but also, gave deliberately deceptive responses to target faces to 'cheat the computer'. subjects were told that the computer could judge whether they were being honest or not. for each trial of the experiment, if subjects cheated the compu ... | 2003 | 14585493 |
| climate, hydrochemistry and economics of surface-water systems (chess): adding a european dimension to the catchment modelling experience developed under lois. | one achievement of the uk land-ocean interaction study (lois) was to link dynamic biogeochemical models of different domains, e.g. rivers, estuaries and coastal waters, and to use the linked model to investigate possible changes from the current status that might occur in the future, for example as the result of climate change. the climate, hydrochemistry and economics of surface-water systems (chess) project has taken the lois methodology forward by exploring possible impacts of climate change ... | 2003 | 14499543 |

| [usefulness of 3d-vibe method in breast dynamic mri: imaging parameters and contrasting effects]. | mr imaging (mri) has been reported to be a useful modality to characterize breast tumors and to evaluate disease extent. contrast-enhanced dynamic mri, in particular, allows breast lesions to be characterized with high sensitivity and specificity. our study was designed to develop three-dimensional volumetric interpolated breath-hold examination (3d-vibe) techniques for the evaluation of breast tumors. first, agarose/gd-dtpa phantoms with various concentrations of gd-dtpa were imaged using 3d-vi ... | 2003 | 12881683 |
| 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 |

| preference, specificity and cheating in the arbuscular mycorrhizal symbiosis. | arbuscular mycorrhizal symbioses are mutualistic interactions between fungi and most plants. there is considerable interest in this symbiosis because of the strong nutritional benefits conferred to plants and its influence on plant diversity. until recently, the symbiosis was assumed to be unspecific. however, two studies have now revealed that although it can be largely unspecific with the fungal community composition changing seasonally, in certain ecosystems it can also be highly specific and ... | 2003 | 12711222 |

| 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 |
| birth order and relationships : family, friends, and sexual partners. | previous studies (salmon 1999; salmon and daly 1998) have found that sex and birth order are strong predictors of familial sentiments. middleborns tend to be less family-oriented than firstborns or lastborns, while sex differences seem to focus on the utility of kin in certain domains. if this is a reflection of middleborns receiving a lesser degree of support from kin (particularly in terms of parental investment), are middleborns turning to reciprocal alliances outside the family, becoming fri ... | 2003 | 26189989 |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |

| 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 |
| evaluation of two-dimensional l-cosy and jpress using a 3 t mri scanner: from phantoms to human brain in vivo. | localized versions of two-dimensional (2d) magnetic resonance spectroscopic (mrs) sequences, namely jpress and l-cosy, have been implemented on a whole-body 3t mri/mrs scanner. volume selection was achieved using three slice-selective radio-frequency (rf) pulses: 90 degrees-180 degrees-180 degrees in jpress and 90 degrees-180 degrees-90 degrees in l-cosy with a chess sequence prior to voxel localization for global water suppression. the last 180 degrees rf pulse was used for resolving the j-coup ... | 2003 | 14648883 |
| [childhood malaria in endemic areas: epidemiology, acquired immunity and control strategies]. | malaria is a major cause of childhood mortality and morbidity in endemic areas. the incidence and severity of malaria depends on various entomological, parasitological, environmental, and human factors. clinical presentation and epidemiologic features vary according to genetic factors, personal behavior, and immune status. populations exposed to frequent infection may develop partial labile protective malarial immunity at the price of high morbidity and mortality due to ineffectiveness of antima ... | 2003 | 14763300 |
| cheating is not always punished: killer female plants and pollination by deceit in the dwarf palm chamaerops humilis. | because the interests of mutualists are not perfectly aligned, conflicts between partners often arise, rendering mutualism unstable by allowing the evolution of cheating. the dwarf palm chamaerops humilis is engaged in a nursery pollination mutualism with a specific weevil derelomus chamaeropsis. in exchange for pollen dispersal, dwarf palms provide pollinators with food, shelter and egg-laying sites, but pollinators can develop only within male inflorescences. here we show that weevils lay eggs ... | 2004 | 15271086 |
| 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 |
| measuring progress in multirobot research with rating methods--the robocup example. | rating the intelligence of artificially made systems is important for measuring progress in scientific and engineering methods. unfortunately, there is currently no universal agreement about what is considered an intelligent system, and how to measure its intelligence. this research focus on measuring the progress in the robotic technologies deployed for the robocup competitions, since one of the original premises of those competitions was to advance the development of intelligent robotic system ... | 2004 | 15376876 |
| 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 |
| 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 |
| 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 |
| 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 |
| novelty seekers and impulsive subjects are low in morningness. | the bipolar dimension of morningness-eveningness refers to the preferred times of day for achieving various activities (i.e. the phase of the circadian clock). it is validated from a biological point of view, associated with at least one gene and heritable through an epistatic mechanism. it has been used as a proxy to study the relationships between the circadian system, personality and psychopathology: there is a correlation between the evening orientation and depression, extraversion and, prob ... | 2004 | 15051106 |
| evaluation of carbohydrate molecular mechanical force fields by quantum mechanical calculations. | a quantitative evaluation of 20 second-generation carbohydrate force fields was carried out using ab initio and density functional methods. geometry-optimized structures (b3lyp/6-31g(d)) and relative energies using augmented correlation consistent basis sets were calculated in gas phase for monosaccharide carbohydrate benchmark systems. selected results are: (i). the interaction energy of the alpha-d-glucopyranose.h(2)o heterodimer is estimated to be 4.9 kcal/mol, using a composite method includ ... | 2004 | 15010301 |
| sports drug testing--an analyst's perspective. | sport plays a major role in the lives of many people, both for active participation and as entertainment. sport is now a huge nationally and internationally based industry. the desire to win has led some athletes to resort to the use of performance enhancing drugs. with huge financial rewards now available in some sports the pressure to excel has grown. some have argued that drug use should be given free rein, however most people are of the view that it is athletic prowess that should be applaud ... | 2004 | 14737504 |

| 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 |

| 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 |
| 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 |
| 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 |
| 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 |

| the hospital manager and game theory: chess master, poker player, or cooperative game player? | hospital management can be seen as a game, and doctors, nurses, and health maintenance organizations are its players. the astute hospital manager realizes the interdependence of individual career strategies and the hospital's success, just as players in a game are interdependent on each other. managers familiar with game theory may successfully transfer that knowledge to the hospital realm. they may recognize patterns and calculate outcomes like chess players, bluff other hospitals into folding ... | 2005 | 14672441 |
| how surveillance begets perceptions of dishonesty: the case of the counterfactual sinner. | three studies support the hypothesis that observers' impressions of actors reflect not only what actors do but also what they can easily be imagined doing. participants in studies 1 and 2 observed a 10-year-old boy take a math test in a context in which the incentive to cheat and the constraints against cheating varied. when the incentive to cheat was high but the likelihood of getting caught was also high, observers perceived a target who resisted the temptation to cheat as less honest than the ... | 2005 | 16162048 |

| correlates of children's eating attitude test scores among primary school children. | a total of 107 malay primary school girls (8-9 yr. old) completed a set of measurements on eating behavior (cheat, food neophobia scales, and dieting experience), the rosenberg self-esteem scale, body shape satisfaction, dietary intake, weight, and height. about 38% of the girls scored 20 and more on the cheat, and 46% of them reported dieting by reducing sugar and sweets (73%), skipping meals (67%), reducing fat foods (60%) and snacks (53%) as the most frequent methods practiced. in general, th ... | 2005 | 15974357 |
| are gender differences in high achievement disappearing? a test in one intellectual domain. | males traditionally predominate at upper achievement levels. one general view holds that this is due only to various social factors such as the 'glass ceiling' and lack of female role models. another view holds that it occurs partly because of innate ability differences, with more males being at upper ability levels. in the last few decades, women have become more achievement focused and competitive and have gained many more opportunities to achieve. the present study examined one intellectual d ... | 2005 | 15906890 |
