Thymus Functionality Needs More Than a Few TECs (open access)

Thymus Functionality Needs More Than a Few TECs

Article is a review exploring the contributions of the many stromal cell types participating in the formation, expansion, and contraction of the thymus under normal and pathophysiological processes. Such information will better inform approaches for restoring thymus functionality, including thymus organoid technologies, beneficial when an individuals’ own tissue is congenitally, clinically, or accidentally rendered non-functional.

Collaborative Clusters: Rethinking User Needs and Breaking Down Barriers

University of North Texas Libraries established an innovative centralized system designed to increase transparency, evidence-based decision-making, and user-centeredness. A series of internal focus groups have revealed that traditional structures continue to silo and homogenize collections. How can libraries better design electronic collections to serve the needs of underserved users? It was presented at the Electronic Resources & Libraries conference held on March 8-11, 2021.

A semi-automated method for extracting channels and channel profiles from lidar-derived digital elevation models

Article introduces a semi-automated method for extracting stream channels and channel profiles from high-resolution digital elevation models (DEMs) using image processing techniques. The method is implemented as an ArcGIS Python add-in toolbar named Channel Extraction and demonstrated using a lidar-derived DEM in a study area along the San Andreas fault in California, USA.

Reduced reflectance and altered color: The potential cost of external particulate matter accumulation on urban Rock Pigeon (Columba livia) feathers (open access)

Reduced reflectance and altered color: The potential cost of external particulate matter accumulation on urban Rock Pigeon (Columba livia) feathers

Authors of the article state that airborne particulate matter (PM) can accumulate on feather surfaces and alter feather appearance, so they quantified PM accumulation on Rock Pigeon feathers and analyzed the spectral properties of extracted particulates. Their findings suggest that wild birds could incur an urban pollution penalty as PM accumulation has the potential to alter feather properties.

The metabolic cost of turning right side up in the Mediterranean spur-thighed tortoise (Testudo graeca) (open access)

The metabolic cost of turning right side up in the Mediterranean spur-thighed tortoise (Testudo graeca)

Article examining the the metabolic cost of self-righting in the terrestrial Mediterranean spur-thighed tortoise using respirometry and kinematic video analysis and comparing this to the metabolic cost of locomotion at a moderate, easily sustainable speed. The results found that self-righting is, relatively, metabolically expensive and costs around two times the mass-specific power required to walk.

Using CRISPR/Cas to enhance gene expression for crop trait improvement by editing miRNA targets (open access)

Using CRISPR/Cas to enhance gene expression for crop trait improvement by editing miRNA targets

Article states that gene editing tools such as CRISPR/Cas9 are often thought of as a means to prevent gene expression; however, a more subtle and yet powerful approach is the enhancement of gene expression by precise deletion of repressor sites within a gene of interest. Authors argue that gene editing of miRNA target sites is preferable over deletion of the miRNA genes themselves, given that it avoids the pitfalls of unspecific derepression of miRNA target(s) beyond the gene of interest.

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.

Dynamic Shear Deformation of a Precipitation Hardened Al0.7CoCrFeNi Eutectic High-Entropy Alloy Using Hat-Shaped Specimen Geometry (open access)

Dynamic Shear Deformation of a Precipitation Hardened Al0.7CoCrFeNi Eutectic High-Entropy Alloy Using Hat-Shaped Specimen Geometry

The article reports on the shear deformation of a eutectic structured HEA and effect of precipitation on shear deformation, particularly Al₀.₇CoCrFeNi high-entropy alloy (HEA). A split-Hopkinson pressure bar (SHPB) was used to compress the hat-shaped specimens to study the local dynamic shear response of the alloy. The change in the width of shear bands with respect to precipitation and deformation rates was studied. The precipitation of L1₂ phase did not delay the formation of adiabatic shear bands (ASB) or affect the ASB width significantly, however, the deformed region around ASB, consisting of high density of twins in fcc phase, was reduced from 80 µm to 20 µm in the stronger precipitation strengthened condition.

Shedding New Light on Weak Emission-Line Quasars in the CIV-Hβ Parameter Space

Article describes how weak emission-line quasars (WLQs) are a subset of Type 1 quasars that exhibit extremely weak Lyα+N V λ1240 and/or C IV λ1549 emission lines. The authors investigate the relationship between emission-line properties and accretion rate for a sample of 230 `ordinary' Type 1 quasars and 18 WLQs at z<0.5 and 1.5<z<3.5 that have rest-frame ultraviolet and optical spectral measurements.
