Connectivity for square percolation and coarse cubical rigidity in random right-angled Coxeter groups

Abstract We consider a random right-angled Coxeter group (RACG), upper W Subscript normal upper Gamma W Γ $W_{\Gamma}$ , whose presentation graph normal upper Gamma Γ $\Gamma$ is taken to be an Erdős–Rényi random graph, i.e. normal upper Gamma tilde script upper G Subscript n com...

Does Medicare Advantage Funding Disparity Affect Managed Care Insurers’ Profitability? Evidence from Puerto Rico

Abstract Introduction Puerto Rico's Medicare Advantage market operates under a persistent yet fluctuating federal funding disparity, with reported benchmark payments approximately 38% below those in United States states. Health insurance industry representatives have argued that...

Mechanisms and therapeutic opportunities of the ribotoxic stress response in cancer

Various environmental and endogenous stressors, including ultraviolet (UV) radiation, cytotoxins, and dysregulated translation, can induce ribosome stalling and collisions, disrupting protein homeostasis. The ribotoxic stress response (RSR) is a cellular surveillance mechanism th...

The Protective Role of Positive Parent-Child Interaction in Mitigating Neurodevelopmental Risks Associated With Preterm Birth

Preterm birth is a well-established biological risk factor for adverse cognitive, behavioral, and emotional outcomes throughout development. However, considerable variability in these outcomes suggests that environmental factors may significantly influence developmental trajector...

A Note on Conditionals Between Lewis and Stalnaker

Abstract I present an infinitely descending chain of normal conditional logics contained in Stalnaker's system VCS (= C2) and show that the intersection of these is Lewis's system VC (= C1). Each system is characterized by a certain generalization of conditional excluded middle....

Benchmark Brown Dwarfs as Chemical Laboratories: Linking System Bulk Properties to Atmospheric Retrievals

Abstract We present the first atmospheric retrieval analysis of two compositional benchmark mid-L dwarfs – SDSSJ141659.78+500626.4 and GJ 499 C – using the Brewster retrieval framework, where the wide benchmark nature of these systems provides independent constraints on age and b...

Understanding genomic landscapes of differentiation in round-tailed horned lizards ( Phrynosoma modestum )

Population divergence is promoted by divergent selection and inhibited by gene flow, but the mechanisms of and relationship between these two processes remain poorly understood. Developing a well-informed hypothesis of the selective pressures underlying divergence in a natural po...

Engineering core-shell polymer microgels to control the onset of glucose-regulated insulin release

Intelligent insulin delivery systems have been a longstanding goal for effective diabetes management with minimized risk of hypoglycemia and reduced discomfort of finger pricks and injections. In this study, core-shell structured microgels are designed to regulate insulin release...

Structural and biophysical characterization of Mycobacterium tuberculosis DciA reveals functional convergence in DnaB helicase recognition

Abstract In bacteria, DnaB replicative helicases are essential for unwinding genomic DNA to provide the single‐stranded templates required for replication. The recruitment of the hexameric DnaB helicase to the origin of replication is mediated by distinct mechanisms that rely on...

Topological polaritons in natural uniaxial materials

Surface polaritons in natural materials offer unique opportunities for tailoring light–matter interactions at the nanoscale. While various classes of surface polaritons have recently been unveiled via near-field imaging techniques, their connection to the underlying topological p...

“I never thought to bring them up to the doctor”: examining symptom appraisal, help-seeking behaviors, and diagnostic delays among young adults with cancer

Abstract Purpose Cancer incidence is rising among young adults (20–39 years), and it is one of the top five causes of death for this age group. Young adults often experience longer delays in diagnosis than children and older adults, which negatively impacts survival and quality o...

SPN 313: Advanced Communication Skills

This syllabus for SPN 313 (Advanced Communication Skills) at the College of Staten Island, CUNY, presents a zero-textbook-cost, OER-based course in advanced academic writing in Spanish designed for a mixed population of heritage speakers and advanced second-language learners. The...

Unexpected Suppression of Tomato Fruit Cuticle Formation by Overexpression of a Key Cutin Biosynthetic Enzyme

Fruit cuticles regulate the diffusion of water, gases and solutes, functioning as essential protective interfaces against environmental and biotic stresses. Engineering cuticle structure and mechanics therefore represents a promising strategy for improving fruit quality and resil...

Testing electron–photon exchange–correlation functional performance for many-electron systems under weak and strong light–matter coupling

We present results for a photon-free exchange–correlation functional within the local density approximation (pxcLDA) for quantum electrodynamics density functional theory (QEDFT), which efficiently describes the electron density of many-electron systems across weak to strong ligh...

Loss of Quasiconvexity in the Periodic Homogenization of Viscous Hamilton–Jacobi Equations

Abstract. We show that in the periodic homogenization of uniformly elliptic Hamilton–Jacobi equations with quasiconvex Hamiltonians in arbitrary dimensions, the effective Hamiltonian is not necessarily quasiconvex. This observation is in sharp contrast with the first-order case,...

A Qualitative Study Identifying Behavioral Science Communication Strategies to Improve Client Engagement and HIV Prevention by Disease Interventionists

Background: Disease Intervention Specialists (DIS), essential implementers of HIV prevention efforts, have increasingly relied on learned empathy, rather than evidence-based strategies for client engagement. Given the mismatch between DIS demands and training, as well as demonstr...

Targeting Oncogenic KRAS Using Peptide Nucleic Acid Oligomers Attached to Cell-Penetrating Peptides

Approximately 30% of tumors contain an activating mutation in the oncogene KRAS, leading to increased cell proliferation that often promotes non-small cell lung cancers, colorectal adenocarcinomas, pancreatic ductal adenocarcinomas (PDAC), and other cancers. Among the most common...

Emerging innovations in movement ecology to address planetary challenges

Abstract Movement ecology—the study of how and why animals move within their environments—stands to offer transformative insights into our rapidly changing world, with benefits for both nature and people. Here, we present the first global horizon scan for movement ecology, engagi...

Mid-infrared long-range surface polaritons in two-dimensional van der Waals materials

The discovery of graphene plasmons (GPs) and hyperbolic phonon polaritons (HPhPs) in two-dimensional (2D) van der Waals (vdW) materials has enabled extreme light confinement and enhanced light-matter interactions, holding the promise for miniaturized mid-infrared (mid-IR) photoni...

An Adult Presentation of KIF11 ‐Related MCLID Syndrome: Case Report and 40‐Year Follow‐Up

Pathogenic variants in KIF11 are linked to autosomal dominant syndromes with microcephaly, chorioretinopathy, lymphedema, and intellectual disability (MCLID), though adult presentations remain underreported. We report a 42-year-old female presenting with a de novo single-amino ac...
