Imposing Observation-Varying Equality Constraints Using Generalised Restricted Least Squares

TL;DR: In this paper, a generalized restricted least squares (GRLS) estimator is proposed for estimating a constant returns to scale production function, which collapses to RLS in cases where the restrictions are observation-invariant.
Journal Article

The combined effect of biological control with plant competition on the management of parthenium weed (parthenium hysterophorus l.)

TL;DR: Biological control and competitive plants can complement one another to bring about improved management of parthenium weed in Australia and this approach may be adopted in countries where some of the biological control agents are already present.

Genetic loci associated with prevalent and incident myocardial infarction and coronary heart disease in the Cohorts for Heart and Aging Research in Genomic Epidemiology (CHARGE) Consortium

TL;DR: One known locus (ANGPTL4), four new loci (PLCL1, RC3H2, TMPRSS5, and LDLRAD1) associated with cardiovascular disease risk that warrant further investigation, and no loci were significantly associated with all-cause mortality following a MI or CHD event.
