Chern - Simons Gauge Field Theory of Two - Dimensional Ferromagnets

A Chern-Simons gauged Nonlinear Schr\"odinger Equation is derived from the continuous Heisenberg model in 2+1 dimensions. The corresponding planar magnets can be analyzed whithin the anyon theory. Thus, we show that static magnetic vortices correspond to the self-dual Chern - Simons solitons and are described by the Liouville equation. The related magnetic topological charge is associated with the electric charge of anyons. Furthermore, vortex - antivortex configurations are described by the sinh-Gordon equation and its conformally invariant extension. Physical consequences of these results are discussed.Comment: 15 pages, Plain TeX, Lecce, June 199

Modelo del desempeño organizacional con mejora continua e invención científica en mypes de productos lácteos

Ecuador – Riobamba city is a cattlee region, where its main source of income is the elaboration of products from fresh milk. Where they have taken 15 micro companies that are dedicated to this area, there are 33 more registered in the MIPRO, which belong to the province of Chimborazo. The purpose of this research is how organizational performance (DO) is directly related to continuous improvement and scientific invention (MC and IC), in which the first must be established in the managers so that the second can be achieved in the processing companies of dairy products. It is concluded that there is indeed a direct influence of the D.O with respect to M.C. and I.C.La ciudad de Riobamba en Ecuador, es una zona ganadera, donde su principal fuente de ingresos es la elaboración de productos a partir de leche fresca. Donde se han tomado a 15 micro empresas que se dedican a este rubro, existiendo 33 más registradas en el MIPRO, que pertenecen a la provincia de Chimborazo. La finalidad de esta investigación es como el desempeño organizacional (D.O) se relaciona directamente con la mejora continua e invención científica, en lo cual el primero debe establecerse en los directivos para que se pueda lograr lo segundo en las empresas procesadoras de productos lácteos. Se llega a la conclusión que efectivamente existe una influencia directa del D.O con respecto a M.C. e I.C.

Multi-ancestry study of blood lipid levels identifies four loci interacting with physical activity.

Many genetic loci affect circulating lipid levels, but it remains unknown whether lifestyle factors, such as physical activity, modify these genetic effects. To identify lipid loci interacting with physical activity, we performed genome-wide analyses of circulating HDL cholesterol, LDL cholesterol, and triglyceride levels in up to 120,979 individuals of European, African, Asian, Hispanic, and Brazilian ancestry, with follow-up of suggestive associations in an additional 131,012 individuals. We find four loci, in/near CLASP1, LHX1, SNTA1, and CNTNAP2, that are associated with circulating lipid levels through interaction with physical activity; higher levels of physical activity enhance the HDL cholesterol-increasing effects of the CLASP1, LHX1, and SNTA1 loci and attenuate the LDL cholesterol-increasing effect of the CNTNAP2 locus. The CLASP1, LHX1, and SNTA1 regions harbor genes linked to muscle function and lipid metabolism. Our results elucidate the role of physical activity interactions in the genetic contribution to blood lipid levels
