Targeting hydroxycinnamoyl CoA: shikimate hydroxycinnamoyl transferase for lignin modification in Brachypodium distachyon (open access)

Targeting hydroxycinnamoyl CoA: shikimate hydroxycinnamoyl transferase for lignin modification in Brachypodium distachyon

This article conducts a study to evaluate the utility of Hydroxycinnamoyl CoA: shikimate hydroxycinnamoyl transferase (HCT) as a target for lignin modification in a species with an “incomplete” shikimate shunt. Results imply that this gene is a preferred target for biotechnological improvement of grasses for bioprocessing.

A modified random network model for P2O5–Na2O–Al2O3–SiO2 glass studied by molecular dynamics simulations (open access)

A modified random network model for P2O5–Na2O–Al2O3–SiO2 glass studied by molecular dynamics simulations

This article investigates the short- and medium-range structural features of sodium aluminosilicate glasses with various P₂O₅ (0–7 mol%) content and Al/Na ratios ranging from 0.667 to 2.000 by using molecular dynamics simulations. Based on the simulated structural information, a modified random network model for P₂O₅-bearing sodium aluminosilicate glass has been proposed, which could be useful to optimize the mobility of sodium ions and design novel functional glass compositions.

Anion-enhanced excited state charge separation in a spiro-locked N-heterocycle-fused push-pull zinc porphyrin (open access)

Anion-enhanced excited state charge separation in a spiro-locked N-heterocycle-fused push-pull zinc porphyrin

This article presents a new type of push–pull charge transfer complex, viz., a spiro-locked N-heterocycle-fused zinc porphyrin, ZnP-SQ, that is shown to undergo excited state charge separation, which is enhanced by axial F⁻ binding to the Zn center. Spectroelectrochemical studies are used to identify the spectra of charge separated states and charge separation upon photoexcitation of ZnP is established.

Caputo Fractional Derivative and Quantum-Like Coherence (open access)

Caputo Fractional Derivative and Quantum-Like Coherence

This article studies two forms of anomalous diffusions and discusses the joint use of these prescriptions, with a phenomenological method and a theoretical projection method, leading to two apparently different diffusion equations. The authors prove that the two diffusion equations are equivalent and design a time series that corresponds to the anomalous diffusion equation proposed.

Classifying Abdominal Fat Distribution Patterns by Using Body Measurement Data (open access)

Classifying Abdominal Fat Distribution Patterns by Using Body Measurement Data

This article aims to explore new categorization that characterizes the distribution clusters of visceral and subcutaneous adipose tissues (VAT and SAT) measured by magnetic resonance imaging (MRI), to analyze the relationship between the VAT-SAT distribution patterns and the novel body shape descriptors (BSDs), and to develop a classifier to predict the fat distribution clusters using the BSDs.

Disentangling Orbital and Valley Hall Effects in Bilayers of Transition Metal Dichalcogenides (open access)

Disentangling Orbital and Valley Hall Effects in Bilayers of Transition Metal Dichalcogenides

This article shows that a bilayer of 2H-MoS₂ is an orbital Hall insulator that exhibits a sizeable orbital Hall effect in the absence of both spin and valley Hall effects. The results are based on density functional theory and low-energy effective model calculations and strongly suggest that bilayers of TMDs are highly suitable platforms for direct observation of the orbital Hall insulating phase in two-dimensional materials.

Shifting Inequalities? Parents’ Sleep, Anxiety, and Calm during the COVID-19 Pandemic in Australia and the United States

This article examines traditional gender roles during the COVID-19 pandemic and its economic fallout as an opportunity to evaluate shifting gender dynamics amidst rapid changes in employment and domestic demands for heterosexual couples with children in Australia and the United States. The authors argue that traditional gender roles were reinforced for U.S. parents but eroded for Australian parents.

The “Malevolent” Benevolence: what happens to perceived immigrant threat when value priorities collide? (open access)

The “Malevolent” Benevolence: what happens to perceived immigrant threat when value priorities collide?

This article examines how self-transcending human values affect perceptions of immigrant threat. Results show that benevolence and universalism tend to affect perceived immigrant threat in opposite directions. A part of individuals’ anti-immigrant bias does not stem from strictly self-interested motivations, as often proposed, but by a sense of loyalty to the interests of our immediate contacts.
