Strong Spatial Mixing for Colorings on Trees and its Algorithmic Applications

Strong spatial mixing (SSM) is an important quantitative notion of correlation decay for Gibbs distributions arising in statistical physics, probability theory, and theoretical computer science. A longstanding conjecture is that the uniform distribution on proper q -colorings on...

Survival of the Flattest: Teams with Low (But Not High) Status Differentiation Turn Failure into Success by Adding High-Status Members

Most prior research on teams’ responses to failure treats teams as closed systems. However, after failures, teams may seek to improve performance by bringing in new members. Adopting a teams-as-open-systems perspective, we test which teams are more willing to add high-status memb...

The history of enzyme evolution embedded in metabolism.

Whereas phylogenetic reconstructions are a primary record of protein evolution, it is unknown whether the deep history of enzymes is encoded at higher levels of biological organization. Here, we demonstrate that the emergence and reuse history of enzymatic folds is embedded withi...

Wear-InducedInterfacial Diffusion in TiN Coatings:A Molecular Dynamics Study

Abstract Understanding the relationship between structural degradation and atomic diffusion is essential for elucidating coating failure at solid interfaces. However, the atomic-scale connection between wear and diffusion remains unclear under coupled thermo-mechanical conditions...

Innovation districts as an institutional strategy: University–industry collaboration, entrepreneurship, and economic development

Universities are increasingly adopting innovation districts as strategic tools to strengthen research commercialization, deepen industry engagement, and contribute to economic development. This paper examines how a public research university has pursued the development of three i...

Local Chemistry-Guided Molecular Beam Epitaxy Growth of SnSe on MgO via Combined ReaxFF Modeling and Machine Learning

Subtle variations in local growth chemistry can fundamentally alter the morphology of layered chalcogenide thin films, yet the atomic-scale mechanisms underlying this sensitivity remain poorly understood. Here, we combine molecular beam epitaxy (MBE) experiments, reactive molecul...

Using PTL Architecture and Surface Chemistry to Control the Nucleation, Distribution, and Morphology of Self-Supported PGM-Free AEM Cathodes

Abstract Self-supported electrodes are increasingly being used in anion exchange membrane electrolyzers. However, a clear understanding of the effects of substrate chemistry and structure is lacking. NiMoO4 nanorods were hydrothermally grown from sodium molybdate and ammonium hep...

Electron Spin‐State Regulation Unlocks Structural Robustness and Stable Sodium Storage in Na 4 Fe 3 (PO 4 ) 2 P 2 O 7 Cathode

ABSTRACT The low‐cost, structurally robust Na 4 Fe 3 (PO 4 ) 2 P 2 O 7 (NFPP) polyanionic cathode for sodium‐ion batteries is constrained by electronic insulation and sluggish Na + transport. Herein, a spin‐state‐engineered cathode, Na 4 Fe 2.94 Mo 0.03 Co 0.03 (PO 4 ) 2 P 2 O 7...

The first steps after paralysis: Immediate locomotor responses following electrically induced loss and recovery of neuromuscular function

Abstract In nature, animals must rapidly regain coordinated locomotion after neuromuscular injury, but the earliest compensatory strategies remain unknown. We addressed this gap using a chronic, implantable kilohertz electrical stimulation (KES) system to reversibly block tibial...

Deciphering the evolutionary origin of the enantioselectivity of short-chain dehydrogenases from plants toward 1-borneol

Abstract Enzyme engineering has produced numerous methods to optimize enzymes for biotechnological processes; however, less is known about how natural evolution creates new functionalities. We investigate the evolutionary emergence of enantioselectivity in plant borneol dehydroge...

Policies for the operation of an ambulance fleet under uncertainty based on a new preparedness metric

Two important decisions in the management of an ambulance fleet are ambulance selection decisions and ambulance reassignment decisions. Ambulance selection decisions determine what to do when an emergency call arrives (such as choosing what ambulance to dispatch to the emergency...

The chiral gyrating H’-T surface family: construction from the dual qtz – qzd nets and existence proof using a toroidal Weierstrass method

Abstract This paper provides an existence proof for a one-parameter family of chiral unbalanced triply periodic minimal surfaces of genus four. We name these gyrating H’-T surfaces because they are related to Schoen’s H’-T surfaces in a similar way as the gyroid is to the primiti...

Altered Complement and Tubular Mitochondrial Proteins Are Linked to Graft Loss in DSA+ Antibody–Mediated Rejection

Background: Antibody-mediated rejection (AMR) is the main driver of late kidney allograft loss. Anti-HLA donor-specific antibodies (DSA) are strongly associated with AMR. However, 30-60% of DSA + patients do not develop AMR, raising the possibility of local tissue adaptations to...

Genomic catalogue of giant viruses reveals expanded diversity and functional potential

Nucleocytoplasmic large DNA and Mirusviricota viruses exhibit taxonomic richness which continually expands due to metagenomic sequencing. Here we curate a database of giant virus metagenome-assembled genomes (GVMAGs V2), comprising 8,508 species-level representatives from 18,727...

Immunization withthe Tc85-Derived Peptide Displayedon Virus-like Particles Confers Protection against Trypanosoma cruzi Infection

Abstract Chagas disease, caused by the Trypanosoma cruzi, remains a major global health burden with limited prophylactic options. We describe a vaccine platform that leverages a peptide epitope derived from the T. cruzi trans-sialidase group II (Tc85pep), displayed on the virus-l...

Gas InvasionPatterns in Saturated Marine Sediments

Abstract Gas invasion into fluid-saturated marine sediments is relevant to various geophysical and environmental processes, such as the formation of gas hydrate reservoirs and their behavior during depressurization-based gas production. The link between pore-scale mechanisms and...

Beyond the Device: A Digital Infrastructure Framework for Sustainable Point-of-Care Diagnostic Services in Low-Resource and Infrastructure-Constrained Settings

Point-of-care and near-patient diagnostics can shorten the time between testing and clinical or public-health action, but a technically effective test does not by itself create a sustainable diagnostic service. Evidence from diagnostic-access research, digitally connected point-o...

Energy dissipation mechanisms in an acoustically driven slit

We quantify the conversion of incident acoustic energy into vortical motion and viscous dissipation for a plane wave passing through large-aspect-ratio slit geometries. We perform direct numerical simulations over a broad imposed parameter space in incident sound pressure level (...

Trions as Fundamental Species in Chemically Doped Polymer Semiconductors

Doping is a cornerstone strategy for enhancing charge transport in semiconducting polymers, important for their application in, for example, semi-transparent electrode materials, thermoelectric devices, and antistatic coatings. Both chemical and electrochemical doping have, for t...

MitigatingSO2 Poisoning Effect in ElectrochemicalCO2 Reduction with Transition-Metal Single-Atom MolecularCatalysts

Abstract The electrochemical CO2 reduction reaction (CO2RR) offers a promising approach for converting captured CO2 into valuable chemicals and fuels. However, CO2 streams from industrial sources often contain SO2 impurities, which compromise the performance and stability of many...
