Structural equation modeling of the associations between amygdala activation, personality, and internalizing, externalizing symptoms of psychopathology
Article examining how amygdala activation to facial expressions was linked with self-report of personality traits and clinical interviews of internalizing and externalizing symptoms of psychopathology. Structural equation modeling results revealed direct associations of amygdala activation with personality trait expression, as well as indirect associations (though personality) with symptoms of psychopathology.

Finding new friends and revisiting old ones – how plant lipid droplets connect with other subcellular structures
Article talks about how the number of described contact sites between different subcellular compartments and structures in eukaryotic cells has increased dramatically in recent years, which has substantially reinforced the well-known premise that these kinds of connections are essential for overall cellular organization. The authors discuss contact sites involving plant lipid droplets (LDs), including LD-endoplasmic reticulum (ER) connections that mediate the biogenesis of new LDs at the ER, LD-peroxisome connections.

Biochar aerogel-based electrocatalyst towards efficient oxygen evolution in acidic media
Article argues that traditional acidic oxygen evolution reaction (OER) electrocatalysts are more prone to be oxidized and corroded as results of unstable carrier structures and variable electronic states of active species, so a high-performing biochar aerogel (BA) based electrocatalyst was realistically designed and synthetized via joint utilization of the terrestrial lignin and seaweed polysaccharide as carbon sources. This work puts forward a novel and effective strategy towards the enhancement of the acidic OER process by rational regulations of the BA and the coupling effect in micro-interface.

Strategic choice in times of stagnant growth and uncertainty: An institutional theory and organizational change perspective
Article provides insight into the strategic behaviors of firms facing slow growth in times of economic stagnation. Using the pertinent literature from institutional theory and organizational change, the authors posit that the appropriate firm-level response (strategic choice) during periods of slow growth is to maintain legitimacy and membership in the field by adopting a proactive approach that focuses on improving top-line growth.

Incorporation of Chiral Frustrated Lewis Pair into Metal–Organic Framework with Tailored Microenvironment for Heterogeneous Enantio- and Chemoselective Hydrogenation
Article states that the development of efficient heterogeneous catalysts with multiselectivity (e.g., enantio- and chemoselectivity) has long been sought after but with limited progress being made so far. To achieve enantio- and chemoselectivity in a heterogeneous system, as inspired by enzymes, the authors illustrate herein an approach of creating an enzyme-mimic region (EMR) within the nanospace of a metal–organic framework (MOF) as exemplified in the context of incorporating a chiral frustrated Lewis pair (CFLP) into a MOF with a tailored pore environment.

Selective Noncatalytic Reduction of NOx Using Ammonium Sulfate
Article discusses how ammonium sulfate (AS) is of interest as an additive in stationary combustion plants for the simultaneous control of NOx (through selective noncatalytic reduction, SNCR) and deposition and corrosion (through sulfation of alkali chlorides). The results indicated that sulfur from ammonium sulfate is mainly released as SO3, even though SO2 is detected in increasing concentrations at temperatures above 1000 °C. This is the accepted manuscript version of the published article.

Complexity synchronization: a measure of interaction between the brain, heart and lungs
Authors of the article address the measurable consequences of the network effect (NE) on time series generated by different parts of the brain, heart, and lung organ-networks (ONs), which are directly related to their inter-network and intra-network interactions. The authors assert that these same physiologic ONs have been shown to generate crucial event (CE) time series, and herein are shown ,using modified diffusion entropy analysis (MDEA) to have scaling indices with quasiperiodic changes in complexity, as measured by scaling indices, over time.

Manipulating microRNA miR408 enhances both biomass yield and saccharification efficiency in poplar
Article describes how the conversion of lignocellulosic feedstocks to fermentable sugar for biofuel production is inefficient, and most strategies to enhance efficiency directly target lignin biosynthesis, with associated negative growth impacts. The authors demonstrate, for both laboratory-and field-grown plants, that expression of Pag-miR408 in poplar significantly enhances saccharification, with no requirement for acid-pretreatment, while promoting plant growth.
