Article presenting cc-pV(n+d)Z correlation consistent basis sets of double- through quintuple-ζ quality for the atoms Al-Ar that have been modified for use with density functional theory (DFT). These basis set modifications include truncation of high-angular momentum basis functions, recontraction of the s- and p-functions, and reoptimization of basis function exponents with generalized gradient approximation and hybrid-DFT functionals. The effects of basis set truncation, recontraction, and reoptimization are shown to improve convergence behavior in atomic energies as well as dissociation energies and enthalpies of formation.

This article is a study using crude oil as an example of an environmental stressor in adult zebrafish. The offspring obtained were then assessed for transgenerational epigenetic transfer of oil-induced phenotypes. The authors conclude that epigenetic transgenerational inheritance can lead to an immediate and simultaneous inheritance of both beneficial and maladaptive traits in a large proportion of the F1 larvae. The adaptive responses may help fish populations survive when facing transient environmental stressors.

Article explores the question of whether animals with switched phenotypes during early development are unable to return to a normal range of adult phenotypes, or whether they do not experience the specific environmental conditions necessary for them to switch back to the normal range of adult phenotypes.

This article explores restoration, rather than protection, being the basis for developing a watershed level strategy for improving water quality in urbanizing watersheds.This study uses a geographical information system (GIS) approach that utilizes riparian characteristics extracted from 40-meter wide corridors centered on streams and rivers. The model was applied to 90 sub-watersheds in the watershed of an important drinking water reservoir in north central Texas, USA.

Article presenting the calculation of the vapour pressure of organic molecules at 298.15 K using a commonly applicable computer algorithm based on the group-additivity method. The standard entropy of vaporization ΔS°vap has been determined and compared with experimental data of 1129 molecules, exhibiting excellent conformance with a correlation coefficient R2 of 0.9598, a standard error σ of 8.14 J/mol/K and a medium absolute deviation of 4.68%.

Article presents a systematic review examining the scientific evidence on the effect of environmental toxicants, air pollutants and endocrine disruptors (EDCs), on compositional and diversity of human microbiota.

Article describing pennycress genome annotation improvements using a combination of long- and short-read transcriptome data obtained from RNA derived from embryos of 22 accessions, in addition to public genome and gene expression information.

Article describes how, in the present study, the water formation was followed by laser absorption with N2O as an oxidant, instead of O2. Three H2S/N2O mixtures diluted in 98% Ar were studied to cover the following range of equivalence ratios: 0.5, 1.0, and 2.0, over a wide range of temperatures (1580–1940 K) around atmospheric pressure.

Article describes how the main functions of thin-walled structures are to reduce the weight of the finished product and to increase the rigidity of the structure. The authors compared the vibration signal for different approaches to machining thin walled-components with vertical walls made of Ti6AI4V titanium alloy and Inconel 625 nickel alloy.

Article describes how connecting organic building blocks by covalent bonds to design porous crystalline networks has led to covalent organic frameworks (COFs), consequently transferring the flexibility of dynamic linkages from discrete architectures to extended structures. Authors state that this review article highlights the fundamental of COFs, including designing principles, coupling reactions, topologies, structural diversity, synthetic strategies, characterization, growth mechanism, and activation aspects of COFs.

Article describes how titanium and nickel alloys are used in the creation of components exposed to harsh and variable operating conditions. The authors state that a search is underway for cutting parameters that will minimize the vibration while meeting the quality requirements.
