FluGenome: a web tool for genotyping influenza A virus

Abstract: Influenza A viruses are hosted by numerous avian and mammalian species, which have shaped their evolution into distinct lineages worldwide. The viral genome consists of eight RNA segments that are frequently exchanged between different viruses via a process known as genetic reassortment. A complete genotype nomenclature is essential to describe gene segment reassortment. Specialized bioinformatic tools to analyze reassortment are not available, which hampers progress in understanding its role in host range, virulence and transmissibility of influenza viruses. To meet this need, we have developed a nomenclature to name influenza A genotypes and implemented a web server, FluGenome (http://www.flugenome.org/), for the assignment of lineages and genotypes. FluGenome provides functions for the user to interrogate the database in different modalities and get detailed reports on lineages and genotypes. These features make FluGenome unique in its ability to automatically detect genotype differences attributable to reassortment events in influenza A virus evolution.

The Effect of Interscholastic Sports Participation on Academic Achievement of Middle Level School Students

Abstract: Eighth graders (N = 136) were divided into two groups: students who had participated in at least one interscholastic sport and were classified as athletes (n = 73), and students who not participate...

Flexomagnetic effect in frustrated triangular magnetic structures

Abstract: We report appearance of the net magnetization in Mn-based antiperovskite compounds as a result of the external strain gradient (flexomagnetic effect). In particular, we describe the mechanism of the magnetization induction in the ${\text{Mn}}_{3}\text{GaN}$ at the atomic level in terms of the behavior of the local magnetic moments of the Mn atoms. We show that the flexomagnetic effect is linear and results from the nonuniformity of the strain, i.e., it is absent not only in the ground state but also when the applied external strain is uniform. We estimate the flexomagnetic coefficient to be $\ensuremath{\sim}2\text{ }{\ensuremath{\mu}}_{B}\text{ }\text{\AA{}}$. We show that at the moderate values of the strain gradient $(\ensuremath{\sim}0.1\mathrm{%})$ the flexomagnetic contribution to the net induced magnetization is comparable with the nonlinear contribution. Finally, we apply a classical Heisenberg model to study the correlation between spin-exchange interaction and flexomagnetism, using time quantified Monte Carlo simulation. This confirms the linear nature of the flexomagnetic effect and helps understanding phenomenological aspects behind it.
