In this paper new methodologies for clustering and dimensionality reduction of large data sets are illustrated using both a least-squares and maximum likelihood approach. The methodologies are described by both real applications and Monte Carlo simulations.

How do we include animals in sociology? Although sociology’s initial avoidance of the nonhuman world may have been necessary to field’s development, recent scholarship – within mainstream sociology, environmental sociology and animal-centred research is helping expand horizons. With a focus on variety, this article reviews four key paths that researchers are taking their research: (1) studying ...

The mobility of chemicals released into the environment governs their bioavailability to organisms and their partitioning between environmental compartments, and thus represents a direct link between environmental pollution and ecotoxicity. The microand mesoscale transport processes involved are related to the properties of the chemicals themselves, but also to environmental compartments. Thus,...

A field experiment was conducted in Crop Research Farm, Department of Agronomy, Sam Higginbottom University Agriculture, Technology and Science, Prayagraj, (U.P), during the zaid season 2022 with objective to study ‟Influence sea weed extract (Kappaphycus alverzii) Zinc on growth yield Blackgram (Vigna mungo L.)”. Pulses are an integral part many diets across globe they have great potential imp...

Recent progress in using effective field theory to describe systems with two nucleons is discussed with particular emphasis placed on the inclusion of pions. Inconsistencies arising in Weinberg’s power counting are demonstrated with two concrete examples. A consistent power-counting scheme is discussed in which pion exchange is sub-leading to local four-nucleon operators. NN scattering in the S...
