Recognition of pathogens relies on families of proteins showing great diversity. Here we construct maximum entropy models of the sequence repertoire, building on recent experiments that provide a nearly exhaustive sampling of the IgM sequences in zebrafish. These models are based solely on pairwise correlations between residue positions but correctly capture the higher order statistical propert...

We provide information regarding the composition of the amphibian community at Yanayacu Biological Station, on the Amazonian slopes of the Andes of Ecuador, and describe a new species of Pristimantis that is referred to the P. myersi group. The new species is distinguished from other species of the group mainly by its color pattern, and by lacking ulnar and tarsal tubercles. The advertisement c...

One of the challenges that global software development teams face is the development of rich and meaningful interactions among members from different countries. Researchers and practitioners in the field are constantly looking for factors that may help organizations understand and mitigate the negative effects that nationality diversity may have on performance in global teams. This paper follow...

Why do some observations lead to broad generalizations whereas other observations do not have as much influence on people's beliefs? One principle of evaluating evidence is the diversity principle, which states that more diverse evidence should lead to stronger inferences than a narrow sample of evidence. For example, if you see someone repeatedly acting aggressively while giving lectures, you ...

one of the main objectives of ecosystem management is to preserve the speciesdiversity. many researchers regard higher species diversity as the stability of ecologicalsystems. the aim of this study is to investigate the stability and relationships betweentopographical factors with diversity indices in ghorkhud mountainous rangeland innorthern khorasan province, iran. for data sampling (2012), l...

Though disparities in birth weight by race/ethnicity have been extensively reported in the United States, few studies have systematically investigated factors attributing to its variability. For 10,638,415 singleton infants born during 2009-2012 in the United States, we examined birth weight differences among 14 races and ethnicities (non-Hispanic white, non-Hispanic Black, American Indian, Asi...

biodiversity plays a crucial role in stability and productivity of natural ecosystem. the main goal of this research was to classify ecological groups in steppe rangeland and investigate their relationships with plant diversity indices. therefore, fifty different land unit tracts (lut) were identified in khod-neuk basin, yazd province, iran, in 2010. vegetation and soil samples were taken in th...

in this study, species richness, evenness and vegetation biodiversity were investigated in stabilized and non-stabilized cut edge areas of chachkam district forest roads in sari forest of iran. 18 micro plots 1×1m (36 micro plots) were sampled to carry out this research on two cut edge areas. number of trees, shrubs and herbaceous were recorded in each micro-plot. significant difference was inv...

One of the issues that have gained a lot of attention in recent years is the board gender diversity. Many researchers believe that gender diversity in the board reinforces corporate social responsibility and on the other hand, gender diversity is one of the signs and effects of corporate social responsibility in the board, so there is a mutual relationship between board gender diversity and cor...
