Differential Take-Up of Supplemental Security Income in Florida for Very Low Birth Weight Infants

OBJECTIVE: Supplemental Security Income (SSI) eligibility is automatically granted for the subset of very low birth weight (VLBW) infants born below 1200 g. We estimated the effects of automatic eligibility on SSI take-up among VLBW infants near the cutoff, both overall and for k...

Patient-Reported Changes in Alcohol Use Following Glucagon-Like Peptide-1 Receptor Agonist Initiation

This survey study with a nationally representative sample evaluates whether individuals who initiate glucagon-like peptide-1 receptor agonists (GLP-1 RAs) report reducing alcohol consumption after starting the drug.

Human, AI, and Hybrid Ensembles for Detection of Adaptive, RL-based Social Bots

The use of reinforcement learning to dynamically adapt and evade detection is now well-documented in several cybersecurity settings including Covert Social Influence Operations (CSIOs), in which bots try to spread disinformation. While AI bot detectors have improved greatly, they...

Cybersecurity as a precondition for the carbon–neutral grid: an investment framework for U.S. utility cybersecurity capital allocation

Abstract The transition to a carbon–neutral electricity system depends on the widespread integration of distributed and inverter-based renewable resources. The U.S. Department of Energy and the North American Electric Reliability Corporation have identified these resources as inc...

A conserved archaeal protein with evolutionary links to bacterial ribosome hibernation and eukaryotic energy sensing

Ribosome hibernation helps cells survive stress by reversibly silencing translation and preserving ribosomal complexes. Although well characterized in bacteria and eukaryotes, archaeal hibernation remains poorly understood. Using cryoEM of archaeal lysates, we identified AHA (AMP...

Setting of Alcohol Use Disorder Diagnosis Among Women Enrolled in Medicare

OBJECTIVE: The authors assessed the setting of an initial diagnosis of alcohol use disorder among Medicare-enrolled women. METHODS: Using 2016-2022 Medicare fee-for-service claims, the authors identified the first alcohol use disorder diagnosis for women ages 18-64 years (N=116,2...

Balanced Notation for τ-Rigid Pairs

We introduce a new notation for τ-rigid pairs called “balanced pairs”. The notation AB allows for simplification of some formulas, for example, the Jasso category and its dual. One of the most compelling formulas is that in the hereditary case, the bricks that label the “covering...

Evaporating universes

Recent work by Headrick, Sasieta and myself provides an extension of the HRT formula for asymptotically flat spacetimes. I use this formula to construct a holographic model of black hole evaporation in four-dimensional asymptotically flat spacetimes using Brill-Lindquist (BL) wor...

Disability Representation in Social and Personality Psychology Research: A State-of-the-Art Review

We conducted a systematic state-of-the-art review examining disability representation of three flagship social and personality psychology journals between 2017 and 2022. First, we examined the 2,343 articles published in that time frame and found that 192 (8.19%) of them used at...

Super-additive multi-dimensional self-balancing deficit: implication for flight mishaps and falling

Abstract We report super-additive impairment in participants using a joystick to stay upright and avoid crashing while riding in a motion simulator programmed to topple as an inverted pendulum away from an upright direction of balance about two axes (2D) relative to 1D. The 2D te...

Different Crystalline Chain Conformations Detected by Nuclear Magnetic Resonance Account for Even–Odd Effects in Biodegradable Polyethylene-Like PE-2, N Polyesters

Abstract The distinct conformations and motions of diol segments in the crystallites of easily accessible polyethylene-like aliphatic polyesters made from C11, C12, C18, or C19 diacids with 13C2-ethylene glycol (PE-2*,11/12/18/19, respectively) were studied by solid-state 13C nuc...

In Situ Multiscale Imaging Reveals Cellular Selection and Remodeling of Peptide Assemblies from Membrane Perturbation to Actin Dysregulation

Abstract Enzyme-responsive peptide nanomaterials can induce non-apoptotic cancer cell death, yet the supramolecular states that mediate activity in cellular environments are usually inferred rather than directly resolved. Here, we integrate multiscale in situ imaging with biochem...

New implementation of mixed-reference spin-flip time-dependent density functional theory and application to molecules with variable diradical character and conical intersections

Mixed-reference spin-flip time-dependent density functional theory (MRSF-TDDFT) improves upon the original spin-flip TDDFT (SF-TDDFT) approach by expanding the configurational space of the response states via a mixed-reference reduced density matrix, specifically, an equal mixtur...

Promiscuous Metal Site in Hepatitis B Virus X Protein Binds an Fe–S Cluster

Abstract Fe–S clusters are emerging as important cofactors in viral replication but are frequently misassigned as Zn due to their O2-sensitivity and overlapping cysteine-based coordination chemistry. The Hepatitis B virus regulatory protein HBx, which is essential for viral repli...

A feature and not a bug: Replication failures can lead to new biology

Much attention has rightly been paid in recent years to the importance of rigorous experimental design and the use of appropriate statistics for data analysis. This is of tantamount importance in the evaluation of clinical trials and because new methods that generate large data s...

Bridging the Policy-to-Practice Gap: Professionals’ Knowledge, Perspectives, and Experiences Following Passage of Legislation Concerning Disabled Parents in Idaho

Parents with disabilities and their children experience disparities within the child welfare system. In response, states are increasingly enacting legislation to protect the rights of these families. As the first state to pass comprehensive legislation concerning parents with dis...

Stereotypical interciliary contacts in a C. elegans sense organ

Physical interactions among cells and their processes are critical for intercellular communication and the generation of ordered tissue patterns. Primary cilia projecting from the cell surface have recently been shown to form contacts with the processes of diverse cell types, as...

Addressing Common Problems in Autism Research: Cohort Development and Sample Description for a Participatory, Real-World, Longitudinal Study of Outcomes in Autistic Adults

Adult autism services research is plagued by methodological challenges, including difficulty obtaining representative or heterogeneous samples and a frequent mismatch between experimental methodologies and real-world settings. The Academic Autism Spectrum Partnership in Research...

Subspace Langevin Monte Carlo

Abstract. Sampling from high-dimensional distributions has wide applications in data science and machine learning but poses significant computational challenges. We introduce subspace Langevin Monte Carlo (SLMC), a novel and efficient sampling method that generalizes random-coord...

A note on gamma factors for pairs

Abstract In this short note we observe that the gamma factor defined by Gelfand and Kazhdan coincides with the Rankin-Selberg root number defined by Jacquet, Piatetskii-Shapiro and Shalika.
