Design of high SERS sensitive substrates based on branched Ti nanorods
Article reports a rational design of branched titanium (Ti) nanorods formed by glancing angle physical vapor deposition and their applications as substrates for surface-enhanced Raman scattering (SERS). The authors investigation provides a mechanism to fabricate sensitive SERS sensors of Ti nanorods that are known to be thermally and chemically stable and compatible with silicon-based electronics.

Multitask deep-learning-based design of chiral plasmonic metamaterials
This article presents an end-to-end functional bidirectional deep-learning (DL) model for three-dimensional chiral metamaterial design and optimization. This ML model utilizes multitask joint learning features to recognize, generalize, and explore in detail the nontrivial relationship between the metamaterials’ geometry and their chiroptical response, eliminating the need for auxiliary networks or equivalent approaches to stabilize the physically relevant output. This model efficiently realizes both forward and inverse retrieval tasks with great precision, offering a promising tool for iterative computational design tasks in complex physical systems. Other potential applications include photodetectors, polarization-resolved imaging, and circular dichroism (CD) spectroscopy.

Synthetic data for annotation and extraction of family history information from clinical text
This article investigates the use of synthetic data for the annotation and automated extraction of family history information relating to cases of cardiac disease from Norwegian clinical text. This work assesses the validity and applicability of the annotated synthetic corpus using machine learning techniques. The methodology outlined in this article may be useful in other situations where limited availability of clinical text hinders NLP tasks.

Regulating C2H2/CO2 adsorption selectivity by electronic-state manipulation of iron in metal-organic frameworks
Article reports a metal electronic-state manipulation strategy to construct a pair of isostructural and interconvertible Fe-MOFs featuring open Fe centers with different electron densities for efficient C₂H₂/CO₂ separation. The authors show that the presence of Fe[II] centers with a medium-spin-state trail plays a crucial role in the enhanced C₂H₂ selective adsorption.

COVID-19 and the gender gap in work hours
Article using panel data from the US Current Population Survey to examine changes in mothers’ and fathers’ work hours from February through April 2020, the period of time prior to the widespread COVID-19 outbreak in the United States and through its first peak. Using person-level fixed effects models, we find that mothers with young children have reduced their work hours four to five times more than fathers.

Trans Accessible Libraries Initiative
Presentation with speakers' notes describing the Trans Accessible Libraries Initiative at the University of North Texas Libraries. This initiative uses findings documented in recent studies addressing information seeking behaviors of transgender persons and their perceptions of the library to provide more equitable access to their services and collections. The presentation shares the needs assessment, collection development process, promotion and outreach, and next steps related to this initiative in hopes that other libraries can modify them to serve marginalized populations in their communities.

Using an Adjunctive Treatment to Address Psychological Distress in a National Weight Management Program: Results of an Integrated Pilot Study
Article examining weight loss and physical functioning of obese veterans with comorbid psychological symptoms when participating in weight management programs. The MOVE! program aims to increase healthy eating and physical activity to promote weight loss in obese veterans. Adequately addressing psychological barriers is necessary to maximize outcomes in MOVE! for veterans with PTSD, depression, and anxiety. This study examined the preliminary outcomes of administering the Healthy Emotions and Improving Health BehavioR Outcomes (HERO) intervention. HERO is adjunctive cognitive-behavioral therapy to MOVE! that addresses PTSD, depression, and anxiety symptom barriers to engagement in physical activity.

Mediterranean Spur-Thighed Tortoises (Testudo graeca) Have Optimal Speeds at Which They Can Minimise the Metabolic Cost of Transport, on a Treadmill
Article experimentally quantifies the metabolic cost of transport in Mediterranean spur-thighed tortoises walking on a treadmill while also quantifying the kinematics of their movement. Results found that tortoises move more efficiently than predicted and presents the first data demonstrating a curvilinear cost of transport over their speed range. The authors conclude that tortoises have an optimum speed at which they move to minimise their metabolic cost of locomotion.

Deep learning for peptide identification from metaproteomics datasets
This article explores a proposed deep-learning-based algorithm called DeepFilter for improving peptide identifications from a collection of tandem mass spectra. The authors find that DeepFilter is believed to generalize properly to new, previously unseen peptide-spectrum-matches and can be readily applied in peptide identification from metaproteomics data.
