Chaotic Origin of Tsirelson Bound

We report a rigorous, deterministic origin for quantum non-locality and the Tsirelson bound (2 2) by revealing profound macroscopic emergent properties hidden within exactly solvable chaos towers under a strictly fixed invariant Cauchy measure (γ = 1). While evaluating joint corr...

A honey trap for Platycerus (Coleoptera: Lucanidae): Georeferenced captures indicate forest-habitat patterns in operational broadleaf forestry

Biodiversity-oriented broadleaf forestry needs practical indicators that translate local forest-habitat conditions into information useful for silvicultural and operational decisions. Here, we used the Female-attracted Flight Interception Trap (F-FIT) to quantify spatial variatio...

Serum C4/C3 ratio at disease onset predicts end-stage renal disease in microscopic polyangiitis: the multicentre REVEAL cohort

We investigated whether serum complement C3 and C4 levels and the C4/C3 ratio at disease onset were associated with clinical features, renal involvement, and prognosis in microscopic polyangiitis (MPA). Patients were stratified into tertiles according to baseline C3 and C4 levels...

Artificial intelligence in cellular senescence research: a systematic review assessing methodological quality and reporting standards using PROBAST + AI and TRIPOD + AI

Cellular senescence is a fundamental mechanism of biological ageing that has emerged as a critical target for therapeutic intervention in age related diseases. The coalesce of artificial intelligence and senescence research provides unprecedented opportunities in advancing our kn...

Denitrative Cyanation of Nitroalkanes by Nucleophilic Substitution through Anion–Radical Coupling

Abstract We report a photocatalytic denitrative cyanation to directly convert nitroalkanes into nitriles under mild conditions. The reaction proceeds rapidly under blue LED irradiation and exhibits broad functional-group tolerance. Mechanistic investigations support an anion–radi...

Effect of Machine Cover on Thermal Behavior of a Turning Center Under Environmental Temperature Changes

Environmental temperature changes are a major factor in machining accuracy degradation in machine tools. As maintaining a constant environmental temperature is costly, reducing thermal deformation through machine design is important. For this purpose, it is essential to clarify t...

Finite-sample Testing of Average Out-of-specification-rate Claims: A Learn-then-test Framework for Design-space Candidates

Abstract Purpose Predictive performance can identify a design-space candidate but cannot establish its quality claim. We developed a finite-sample procedure for a prespecified average out-of-specification (OOS) rate claim under a reference plan. Methods Construction data ranked o...

Concise Total Synthesis of Streptospherin A

Abstract A practical total synthesis of streptospherin A (1), a cancer stem cell inhibitor, is reported. The key intermediates are obtained stereoselectively in a concise synthesis by a combination of asymmetric allylation and hydroxy-directed stereoselective diboration. These in...

Evaluation of clinical prognostic factors for radium-223 therapy in castration-resistant prostate cancer with bone metastases: the KYUCOG-1901 study

We evaluated clinical factors associated with symptomatic skeletal events (SSEs), radiographic progression-free survival (rPFS), and overall survival (OS) in patients with metastatic castration-resistant prostate cancer (mCRPC) and bone metastases treated with radium-223 (Ra-223)...

Statistics of Solar Filament Mass Based on CHASE Sun-as-a-star Spectroscopic Observations

Abstract Filaments are cool and dense plasmas suspended in the hot corona of the Sun and other stars. Accurately estimating their masses is of great significance for understanding subsequent eruptions and induced space weather effects, but it remains hindered by their intrinsic g...

Discrete Pitch-Angle Conditions for Helicoidal Stacking of Periodically Corrugated Rods

Helical laminates, in which fibrous elements are stacked while rotating by a constant angle from one layer to the next, are common in natural and artificial materials, including Bouligand structures and fiber-reinforced composites. This study clarifies the geometric pitch-angle c...

High-temperature-treated soy protein isolate reduces amino acid availability and alters social novelty in mice

Abstract High-temperature (HT) treatments above 100 °C are important in food processing; however, their effects on the nutritional value of moist heat-treated proteins are less understood. Therefore, this study examined the impact of HT at 121 °C on soy protein isolate (SPI) in w...

Epidemiology of macular dystrophy in Japan (2011–2020): a nationwide population-based study

Abstract Purpose To describe the characteristics and prevalence of macular dystrophy using a comprehensive national claims database in Japan. Study design Population-based retrospective study using a nationwide claims database. Methods Approximately 126 million individuals covere...

Systematic global structure search of bismuth-based binary systems under pressure using machine learning potentials

Machine learning potentials (MLPs) have significantly advanced global crystal structure prediction by enabling efficient and accurate property evaluations. In this study, global structure searches are performed for 11 bismuth-based binary systems, including Na-Bi, Ca-Bi, and Eu-B...

Assessing Disaster Preparedness and Recovery from Tropical Cyclones in Zimbabwe: Insights from Cyclone Ana in Nyanga

Abstract Tropical cyclones pose increasing risks in Southern Africa, with impacts shaped not only by hazard intensity but also by underlying vulnerabilities and disaster risk management (DRM) capacity. This study examines preparedness, response, and recovery following Cyclone Ana...

Development of quality indicators for diabetes care in community pharmacies: a modified Delphi method

Abstract Background Type 2 diabetes is a common chronic condition requiring continuous management. Without a healthy lifestyle and regular treatment, it can lead to severe complications that greatly reduce the patients’ quality of life. Although support for medication management...

Type-II-like ultrafast demagnetization behavior in NiCo2O4 thin films

Rare-earth-free ferrimagnetic oxides are emerging as attractive platforms for investigating ultrafast spin dynamics. Here, we study the photoinduced magnetization dynamics of epitaxial NiCo2O4 (NCO) thin films by the time-resolved magneto-optical Faraday effect using two independ...

Podocyte injury damages podocytes in chimeric organoids

Abstract We have previously shown that injury to a subset of podocytes can trigger secondary damage in neighboring podocytes, but whether this phenomenon depends on direct intercellular interaction is unknown. To address this, kidney organoids were generated from nephron progenit...

ProvMind: provenance-grounded reasoning for materials synthesis

Materials process optimization requires reasoning over routes, conditions, tools and material-flow dependencies, yet most computational formulations flatten synthesis procedures into text or ordered steps. We introduce MatProcBench, a provenance-grounded benchmark constructed fro...

Digital Interaction Rituals and the Transformation of Loneliness

ABSTRACT Consumer research has largely treated loneliness as a chronic, trait‐level deficit that consumers compensate for through consumption. Much less is known about situational loneliness, the transient yet emotionally charged form of loneliness that arises within consumption...
