The pseudo-potential method is applied to derive diverse propagating electron hole structures, in a nonthermal or $\kappa$ particle distribution function background. associated Ansatz reproduces the Schamel of \cite{Schamel2015} Maxwellian ($\kappa \rightarrow \infty$) limit, providing significant generalization it for plasmas where superthermal electrons are ubiquitous, such as space plasmas. ...

Objective. To determine the Cryptosporidium spp. infection frequency by using Ziehl-Neelsen and Auramine stains on samples obtained from diarrheic calves from milking farms of the Valdivia province. To compare both diagnostic tests and to determine the geospatial distribution of the infections caused by this protozoan. Materials and methods. 221 fecal samples of diarrheic calves of 24 milking f...

The phylogenetic relationships of Ig light chain (IGL) genes are difficult to resolve, because these genes are short and evolve relatively fast. Here, we classify the IGL sequences from 12 tetrapod species into three distinct groups (kappa, lambda, and sigma isotypes) using conserved amino acid residues, recombination signal sequences, and genomic organization of IGL genes as cladistic markers....

This study focuses on 10 BALB/c anti-influenza virus (A/PR/8/34) hemagglutinin antibodies that have light chains encoded by the same variable region kappa chain (V kappa) gene, V kappa 21C. A comparison of antibodies from lymphocytes of independent origin reveals the contribution of germline diversity (combinatorial joining and association) to this response. Although combinatorial joining and a...
