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.

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.

A smartphone-based online system for fall detection with alert notifications and contextual information of real-life falls (open access)

A smartphone-based online system for fall detection with alert notifications and contextual information of real-life falls

This article presents the results of a prospective study investigating a proof-of-concept, smartphone-based, online system for fall detection and notification. Apart from functioning as a practical fall monitoring instrument, this system may serve as a valuable research tool, enable future studies to scale their ability to capture fall-related data, and help researchers and clinicians to investigate real-falls.

Acetaldehyde oxidation at elevated pressure (open access)

Acetaldehyde oxidation at elevated pressure

A detailed chemical kinetic model for oxidation of CH3CHO at intermediate to high temperature and elevated pressure has been developed and evaluated by comparing predictions to novel high-pressure flow reactor experiments as well as shock tube ignition delay measurements and jet-stirred reactor data from literature. The flow reactor experiments were conducted with a slightly lean CH3CHO/O2 mixture highly diluted in N2 at 600–900 K and pressures of 25 and 100 bar. This is the accepted manuscript version of the published article.

Self-reporting molecularly imprinted polymer with the covalently immobilized ferrocene redox probe for selective electrochemical sensing of p-synephrine

Article simultaneously imprinting the p-synephrine 1 template and covalently immobilizing a a ferrocene redox probe in a (bis-bithiophene)-based polymer. The resulting molecularly imprinted polymer (MIP) was deposited on the Pt electrode as a thin film to form a redox self-reporting MIP film-based chemosensor.

Evidence of Endozoochory in Upland Geese Chloephaga picta and White-Bellied Seedsnipes Attagis malouinus in Sub-Antarctic Chile (open access)

Evidence of Endozoochory in Upland Geese Chloephaga picta and White-Bellied Seedsnipes Attagis malouinus in Sub-Antarctic Chile

This article evaluates the role of endozoochory in herbivorous and sympatric bird species in sub-Antarctic Chile. The authors hypothesize that fragments of bryophyte gametophytes retrieved from their feces are viable and capable of regenerating new plant tissue. This relationship may have important implications in the way bryophytes disperse and colonize habitats facing climate change.

Design approaches for printability-performance synergy in Al alloys for laser-powder bed additive manufacturing (open access)

Design approaches for printability-performance synergy in Al alloys for laser-powder bed additive manufacturing

This article highlights that design of Al alloys for laser-powder bed fusion (L-PBF) can lead to fundamental change in the microstructure evolution, proposed alloy design strategies lead to synergy between and printability and performance, hierarchical and heterogeneous microstructures have potential to overcome the strength-ductility tradeoff, and alloy design incorporating the specific attributes of an AM technology is crucial to maximizing its potential.

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.
