An investigation into the effects and effectiveness of correlation network filtration methods with financial returns

Plos.org 

by Tristan Millington

When studying financial markets, we often look at estimating a correlation matrix from asset returns. These tend to be noisy, with many more dimensions than samples, so often the resulting correlation matrix is filtered. Popular methods to do this include the minimum spanning tree, planar maximally filtered graph and the triangulated maximally filtered graph, which involve using the correlation network as the adjacency matrix of a graph and then using tools from graph theory.

Selection on modifiers of genetic architecture under migration load

Plos.org 

by Stephen R. Proulx, Henrique Teotónio

Gene flow between populations adapting to differing local environmental conditions might be costly because individuals can disperse to habitats where their survival is low or because they can reproduce with locally maladapted individuals. The amount by which the mean relative population fitness is kept below one creates an opportunity for modifiers of the genetic architecture to spread due to selection. Prior work that separately considered modifiers changing dispersal... Читать дальше...

A multi-label learning model for predicting drug-induced pathology in multi-organ based on toxicogenomics data

Plos.org 

by Ran Su, Haitang Yang, Leyi Wei, Siqi Chen, Quan Zou

Drug-induced toxicity damages the health and is one of the key factors causing drug withdrawal from the market. It is of great significance to identify drug-induced target-organ toxicity, especially the detailed pathological findings, which are crucial for toxicity assessment, in the early stage of drug development process. A large variety of studies have devoted to identify drug toxicity. However, most of them are limited to single organ or only binary toxicity. Читать дальше...

Identifying enhancer properties associated with genetic risk for complex traits using regulome-wide association studies

Plos.org 

by Alex M. Casella, Carlo Colantuoni, Seth A. Ament

Genetic risk for complex traits is strongly enriched in non-coding genomic regions involved in gene regulation, especially enhancers. However, we lack adequate tools to connect the characteristics of these disruptions to genetic risk. Here, we propose RWAS (Regulome Wide Association Study), a new application of the MAGMA software package to identify the characteristics of enhancers that contribute to genetic risk for disease. RWAS involves three steps... Читать дальше...

Searching for serial dependencies in the brain

Plos.org 

by David Whitney, Mauro Manassi, Yuki Murai

Identifying the neural correlates of visual serial dependence has lagged behind the behavioral understanding. A new study in PLOS Biology provides a model of interpreting the complex relationship between physiology and behavior in studies of serial dependence. Our senses are barraged with discontinuous and uncertain visual input, but the brain smooths experience by making perception serially dependent. Neural correlates of this have been elusive...

Glutamate and clock help bean bugs track seasonal reproductive changes

Plos.org 

by Sergio Hidalgo, Joanna C. Chiu

Animals adapt their seasonal physiology by measuring photoperiodic changes over the calendar year. A new study in PLOS Biology uncovers changes in glutamate dynamics in the bean bug that are dependent on photoperiod and a clock gene. Animals adapt their seasonal physiology by measuring photoperiodic changes over the calendar year, but the neuronal mechanisms conveying this information are unclear. This Primer explores a new PLOS Biology study that sheds... Читать дальше...

Do you remember Maslow’s Hierarchy of Needs from college? It’s that pyramid of things that humans need, physiologically or psychologically, to survive. Sure, Maslow himself never imagined the hierarchy, instead preferring to see all needs as, well, needed, but we can spin the idea into something useful to us:…
