Genetic Differentiation of the South Florida Red-Shouldered Hawk (Buteo lineatus extimus) from the Nominate Subspecies (Buteo lineatus lineatus)
Article discusses how the south Florida subspecies of the Red-shouldered Hawk (Buteo lineatus extimus) is distinctly paler and smaller than other subspecies, reproduces at a lower rate, and can occupy very different habitats such as open marshes and grasslands with only scattered trees. The authors evaluated population differentiation between the south Florida population of Red-shouldered Hawks and two populations of eastern Red-shouldered Hawks (B. l. lineatus) in suburban (Cincinnati) and rural (Hocking Hills) environments in southern Ohio.

The chemical coupling between moist CO oxidation and gas-phase potassium sulfation
Article discusses how the chemical coupling between moist CO oxidation and transformation of gaseous potassium salts (KCl or KOH) in the presence and absence of SO2 was investigated experimentally and through chemical kinetic modeling. Analysis of the calculations indicates that sulfation pathways in the model involving KOSO3 contribute to the overprediction, but both the thermodynamic properties and rate constants in the model involve significant uncertainties and more work is required to resolve the discrepancy.

Linking random forest and auxiliary factors for extracting the major economic forests in the mountainous areas of southwestern Yunnan Province, China
Article describes how forests are generally extracted from remotely sensed images based on the spectral features, ignoring other important auxiliary information, and the techniques of precise extraction need to be further improved. By using the Sentinel–2 image and auxiliary factors (AFs) including site conditions (SCs) and vegetation indices (VIs), the random forest model with AFs (RF–AFs) was adopted for the extraction of the economic forests in Lancang County.

Optical in-situ measurements and modeling of post-flame sulfation of NaOH(g) and NaCl(g)
Article describes post-flame sulfation of gaseous sodium hydroxide (NaOH) and sodium chloride (NaCl) was investigated with optical in situ measurements at 850 to 1475°C. The combined experimental data, chemical equilibrium calculations and kinetic modeling of the present study support that sulfation of alkali species can occur in the gas phase through homogeneous reactions.

Quantum algorithm for electronic band structures with local tight-binding orbitals
Article says that while the main thrust of quantum computing research in materials science is to accurately measure the classically intractable electron correlation effects due to Coulomb repulsion, designing optimal quantum algorithms for simpler problems with well-understood solutions is a useful tactic to advance our quantum “toolbox”. In this paper, the authors adopt a direct space approach, using a novel hybrid first/second-quantized qubit mapping which allows us to construct a single Hamiltonian, and a single cost-function, suitable for solving the entire electronic band structure.

Transgenic manipulation of triacylglycerol biosynthetic enzymes in B. napus alters lipid-associated gene expression and lipid metabolism
Article asserts that oilseed rape (Brassica napus) is an important crop that is cultivated for the oil (mainly triacylglycerol; TAG) it produces in its seeds. The author's results show that up-regulation of these key enzymes differentially affects lipid composition and distribution as well as lipid-associated gene expression, providing important information which could be used to improve crop properties by metabolic engineering.

Tuning excited state electronic structure and charge transport in covalent organic frameworks for enhanced photocatalytic performance
Article describes how covalent organic frameworks (COFs) represent an emerging class of organic photocatalysts. The authors use reticular chemistry to construct a family of isoreticular crystalline hydrazide-based COF photocatalysts, with the optoelectronic properties and local pore characteristics of the COFs modulated using different linkers.

Metabolic reprogramming underlies cavefish muscular endurance despite loss of muscle mass and contractility
Article discusses the Mexican cavefish Astyanax mexicanus, has lost moderate-to-vigorous activity following cave colonization, reaching basal swim speeds ~3.7-fold slower than their river-dwelling counterpart. Collectively, the authors reveal broad skeletal muscle changes following cave colonization, displaying an adaptive skeletal muscle phenotype reminiscent to mammalian disuse and high-fat models while simultaneously maintaining a unique capacity for sustained muscle contraction via enhanced glycogen metabolism.

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.
