Testing in Microbiome-Profiling Studies with MiRKAT, the Microbiome Regression-Based Kernel Association Test
AMERICAN JOURNAL OF HUMAN GENETICS, 96(5), 797–807.
MeSH headings : Computer Simulation; Genetics, Population; High-Throughput Nucleotide Sequencing; Humans; Microbiota / genetics; Models, Statistical; Phylogeny; Polymorphism, Single Nucleotide; Software
TL;DR:
The microbiome regression-based kernel association test (MiRKAT), which directly regresses the outcome on the microbiome profiles via the semi-parametric kernel machine regression framework, is proposed and applied to real microbiome datasets to show that microbial communities are associated with smoking and with fecal protease levels after confounders are controlled for.

Roles of Solvent Accessibility and Gene Expression in Modeling Protein Sequence Evolution
EVOLUTIONARY BIOINFORMATICS, 11.
author keywords: protein evolution; protein structure; gene expression; codon usage; scaled selection coefficient; solvent accessibility
TL;DR:
It is come to the biologically plausible conclusion that both RSA and gene expression are related to amino acid frequencies, but, among synonymous codons, the relative probability of a particular codon is more closely related to gene expression than RSA.

author keywords: Functional data analysis; Functional regression model; Mixed model; Multiple functional predictors; Penalized splines; Tractography data
TL;DR:
A general framework for smooth regression of a functional response on one or multiple functional predictors is proposed using the mixed model representation of penalized regression, which allows for seamless integration of continuous or categorical covariates and provides approximate confidence intervals as a by-product of the Mixed model inference.

Identifying Greater Sage-Grouse source and sink habitats for conservation planning in an energy development landscape
ECOLOGICAL APPLICATIONS, 25(4), 968–990.

TL;DR:
The results provide evidence that energy development and avoidance of energy infrastructure were probably reducing the amount of source habitat within the ARPA landscape, and a source-sink map provides managers with a means of prioritizing habitats for conservation planning based on source and sink dynamics.
