BackgroundRecent studies have shown that when individuals are grouped on the basis of genetic similarity, group membership corresponds closely to continental origin. There has been considerable debate about the implications of these findings in the context of larger debates about race and the extent of genetic variation between groups. ...
For the past three years we have presented results of several large-scale earthquake simulations run by different research groups, but these have been limited to qualitative comparisons. This work presents a preliminary verification of three simulation sets for the ShakeOut earthquake scenario, version 1.1, an Mw 7.8 earthquake on a portion of the San ...
Regardless of the extremely subtle acoustic changes that are perceptible within almost all perception research studies, it is the total overall effect that generally occupies each individual listener. A long line of research indicates that many subtle "music changes" are often not perceived accurately and are actually mistakenly identified. Another line of research indicates ...
Birds rely, at least in part, on spatial memory for recovering previously hidden caches but accurate cache recovery may be more critical for birds that forage in harsh conditions where the food supply is limited and unpredictable. Failure to find caches in these conditions may potentially result in death from starvation. In order to test this hypothesis we compared the cache ...
In colonial species, recognition of offspring should be under strong selection. For accurate identification to occur offspring must emit individually distinctive signals and parents must be able to discriminate between signals. Female greater spear-nosed bats (Phyllostomus hastatus) roost in stable social groups and use infant vocalizations, termed ...
The value of any given technology may be different for different groups of people and at different points in time.
An accurate representation of task-set information is needed for successful goal directed behavior. Recent studies point to disturbances in the early processing stages as plausible causes for task-switching deficits in schizophrenia. A task-cueing protocol was administered to a group of schizophrenic patients and compared with a sample of age-matched ...
Museums have the capacity to enhance social cohesion, which is the product of a trusting, connected community. History museums and historic sites, in particular, can serve communities by stimulating dialogue on difficult issues, accurately representing all the people of a nation, and creating forums for discussion among groups with disparate opinions. ...
To examine whether psychopaths exhibit specific deficits in nonverbal emotional processing, 20 criminal psychopaths, 23 criminal nonpsychopaths, both groups identified with Hare's (2003) Psychopathy Checklist-Revised, and 25 noncriminals completed the facial affect recognition test developed by Philippot et al. (1999). All participants were males. The criminal psychopaths and ...
The proper application of biotic ligand models to predict metal toxicity depends on accurate prediction of metal binding to sites on natural organic matter (NOM) which compete with the 'biotic' ligand for available metal. A hard and soft metal classification along with associated ligand groups (carboxyl, phenolic, amino, sulfidic) are used as a basis to ...
We sought to identify biomarker responses to tuberculosis specific antigens which could 1) improve the diagnosis of tuberculosis infection and 2) allow the differentiation of active and latent infections. Seventy subjects with active tuberculosis (N = 12), latent tuberculosis (N = 32), or no evidence of tuberculosis infection (N = 26) were evaluated. We used the Luminex Multiplexed Bead Array ...

Bacteriol. 89:159�169. 1965.�For some time, streptomycete taxonomists have been seeking to describe more accurately the colors of aerial mycelium. Some of the descriptive systems involve many ...
BackgroundpKa values are a measure of the protonation of ionizable groups in proteins. Ionizable groups are involved in intra-protein, protein-solvent and protein-ligand interactions as well as solubility, protein folding and catalytic activity. The pKa shift of a group from its intrinsic ...
A recent study has shown that the sensorimotor memory for the fingertip forces used to grasp and lift an object can be shared across two prehension tasks. However, the persistence (or decay) of these memory resources is not known. Reports of within-task sensorimotor memory indicate persistence of lifting forces, with evidence for reduced persistence of grip forces. Here we investigated the ...
This investigation assessed awareness of the oral cavity of nonnative speakers acquiring English. University students (60 men, 60 women) were placed into three equal-size groups. The Less Experienced group lived in the USA less than 6 mo. (M = 3.3 mo., SD = 2.4). The More Experienced group lived in the United States 3 or more years (M ...
Linear groups�polypeptide conformations based on a single repeating ?,?-pair�are a foundational concept in protein structure, yet how they are presented in textbooks is based largely on theoretical studies from the early days of protein structure analysis. Now, ultra-high resolution protein structures provide a resource for an accurate empirical and ...
The authors present their experience in the medical treatment of 1, 296 caustic esophageal injuries in children over the last 20 years in two study groups, one comprising the period up to 1989 and the other 1990 to 1996, comparing the different treatments used in each group. The treatment was based fundamentally on dilatations with ...
Although it has been suggested that large animal groups should make better decisions than smaller groups, there are few empirical demonstrations of this phenomenon and still fewer explanations of the how these improvements may be made. Here we show that both speed and accuracy of decision making increase with group size in fish shoals ...
Comments on a paper by H. S. Kim, D. K. Sherman, and S. E. Taylor in regards to the consideration of culture, ethnicity, and national origin in the study of individual and group differences and social interactions. Erard claims that their attempt to infer from small, mostly college-student samples examined on a handful of variables in a few dozen studies ...
The technetium phosphate bone scans of 106 children with suspected septic arthritis were reviewed to determine whether the bone scan can accurately differentiate septic from nonseptic arthropathy. Only 13% of children with proved septic arthritis had correct blind scan interpretation. The clinically adjusted interpretation did not identify septic arthritis in 30%. Septic ...
An estimation method was developed to predict ideal gas heat capacities over the temperature range from 300 to 1500 K. The only information required are the types and numbers of different elements comprising a molecule. This method gives numeric results only slightly inferior to more rigorous methods and has the advantage of being general in the sense that calculations can be ...
Proposals of alternative electric-utility rate structures require analysis of the impacts they are likely to have on various customer groups. This, in turn, requires knowledge of the end-use and demographic factors that determine consumption. Empirical work by the authors, described in this article, leads to a conclusion that the influencing factors vary from service area to ...
In this lesson, students take samples from an unseen model of the ocean floor and try to accurately describe its composition. It will introduce the students to the limitations of sampling and the problem of obtaining representative samples of sea floor sediments. The lesson can also be an introduction to a study of geological oceanography or local geology. Younger children can ...
The Perseus-Andromeda group of constellations is the largest in the sky, yet many other Greek myths have no dedicated star at all. The author interprets the importance given to this myth in terms of its role of providing ethnic identify for the Greeks who created it. An accurate analysis of the myth, also including the etymology of the characters' names, ...
Linear response theory coupled to molecular dynamics simulations with an explicit solvent representation is used to derive fractional contributions of amino acid residues to the solvation of proteins. The new fractional methods developed here are compared with standard approaches based on empirical 1D and 3D statistical potentials, as well as with estimates obtained from the analysis of classical ...
We control the generation of solitons and solitonlike pulses in a passively mode-locked dye laser by adjustment of group-velocity dispersion, self-phase modulation, and spectral filtering. Without spectral filtering, periodic pulse shaping reminiscent of higher-order solitons is observed. The pulses differ from the classic solitons because of additional ...
The characteristics of the disturbances in the atmosphere and oceans and in other stably stratified and rotating fluids are analyzed according to their phase and group velocities. It is shown that both stable stratification and rotation augment the velocity of the sound waves, and that the internal gravity waves and inertial waves are mutually exclusive when the ...
