An Infinite Family of Near-Magic Squares of Squares: the 9p4 Conjecture

Whether a 3 ×3 magic square can be built from nine distinct perfect squares is a celebrated open problem of LaBar and Gardner. Relaxing it by one line yields Lee Sallows’ classical near- miss: nine distinct squares whose three rows, three columns and one diagonal share the common...

Bulk degradation of P-, Sb- and As-doped Cz Si wafers and TOPCon cells due to light and elevated temperature

We assessed light- and elevated-temperature induced degradation (LeTID) in n -type Czochralski (Cz) Si wafers, and industrial tunnel oxide passivating contact (TOPCon) Si solar cells processed with and without the laser-enhanced contact optimization (LECO). A recovery pre-treatme...

A Technology-Blended Exercise Intervention for Cognitive Risk Reduction and Brain Health in Middle-Aged and Older Adults with Type 2 Diabetes in Singapore

BACKGROUND: Type 2 diabetes mellitus (T2DM) is a major modifiable risk factor for accelerated brain ageing, cognitive decline, and dementia. However, sustainable lifestyle interventions targeting cognitive health in at-risk older adult populations remain limited. This mixed-metho...

Emergent MOND from Cosmological Horizon Thermodynamics: Unruh-Hawking Resonance and the Redshift Evolution of the Critical Acceleration

The empirical success of Modified Newtonian Dynamics (MOND) contrasts sharply with its lack of a fundamental microscopic mechanism. We propose a radical conceptual breakthrough: the MOND critical acceleration a₀ is not a fundamental constant, but a macroscopic emergent phenomenon...

The second language acquisition of reflexives in Japanese by Chinese and Korean learners

Abstract This study investigates the second language processing and interpretation of the Japanese reflexive zibun ‘self’ by Chinese and Korean learners of Japanese. This is motivated by the pragmatic influence on anaphoric resolution in these three languages, allowing insight in...

Scenario-based energy simulation of tree planting strategies to reduce the heating and cooling demand of buildings under 2050 climate conditions

Abstract. Urban areas account for a large share of global energy use and emissions and face increasing climate- and heat-related challenges. These conditions drive the development of district-scale strategies such as Positive Energy Districts. Urban Building Energy Modelling (UBE...

Clinical characteristics and influencing factors of roxadustat-induced central hypothyroidism in patients receiving peritoneal dialysis

Background This study aimed to investigate the clinical characteristics and risk factors of central hypothyroidism (CEH) in peritoneal dialysis (PD) patients treated with roxadustat. Methods This retrospective study enrolled maintenance PD patients followed up at Peking Universit...

Wavelength- and Energy-Dependent Nonlinear Absorption and Transient Absorption in Silver Nanoparticles

Nonlinear absorption (NLA) in silver nanoparticles (Ag NPs) is strongly affected by plasmonic field enhancement. However, its wavelength- and energy-dependent evolution on the red side of the surface plasmon resonance (SPR) band remains insufficiently understood. Here, we systema...

Mechanistic Tomography: Designed Measurement for Control-Oriented Interpretability

Mechanistic interpretability seeks quantities that a model does not expose directly: represented states, component effects, interactions, and responses to interventions. Patching, gradients, Hessian-vector products, and subset interventions obtain different measurements under dif...

Antecedents and outcomes of corporate digital social responsibility in hospitality and tourism: a systematic review and integrative framework

This study synthesises corporate digital social responsibility (CDSR) research in hospitality and tourism and proposes an integrative framework linking antecedents, digital design characteristics, mechanisms, and outcomes. Using structured search logic and PRISMA-aligned screenin...

The Triple Burden of Administrative Tasks Among US Family Medicine Physicians—A Cross-sectional Study

Abstract Background Although interoperability advances and policy initiatives have expanded EHR functionality and were intended to streamline clinical workflows, many administrative tasks remain burdensome. Objective To describe the prevalence and co-occurrence of three administr...

Design and Implementation of a High-Precision Braille Recognition System Based on Biomimetic Multi-Convex-Points U-Shaped Micro-Nano Fiber

Abstract As a vital medium for visually impaired individuals to access textual information, Braille recognition technology plays a crucial role in enhancing this group's ability to access information without barriers. To address the limitations of existing Braille recognition tec...

Co-sedimentation is the key to the structural investigation of wild-type FAT10

Under inflammatory conditions, the ubiquitin-like modifier FAT10 serves as a tag for protein degradation by the 26S proteasome. FAT10 is degraded along with its substrates and this process is independent of the segregase VCP/p97, which, in the regular ubiquitin pathway of degrada...

A rare combination of gastroschisis, jejunal atresia, colonic atresia, and midgut malrotation in a newborn: a case report and literature review

Introduction and importance: Gastroschisis is a congenital full-thickness anterior abdominal wall defect that allows bowel evisceration without a covering sac. While most cases are isolated and have good outcomes, complex gastroschisis involves associated intestinal pathology and...

DFT Study on EfficientElectrocatalytic Nitric OxideReduction to Hydroxylamine over TM/Ti3C2O2 in Aqueous Solution

Abstract Electrocatalytic selective reduction of nitric oxide (NORR) provides a feasible pathway for the green synthesis of hydroxylamine (NH2OH) under mild conditions. Maintaining N–O bond integrity is critical for NH2OH selectivity, as it prevents the formation of ammonia. Sing...

Ecological Restoration of Degraded Mining Soils Through Key‐Layer Construction Using Industrial By‐Products: A Comprehensive Analysis of Soil Physics, Microbiology, and Maize Yield

ABSTRACT Coal mining severely degrades soil profiles and ecosystem functions, highlighting the need for effective reclamation. Reconstructing soil profiles with industrial solid wastes offers a promising waste‐to‐resource approach, but the ecological effects of different engineer...

Hydroxybenzoate-based hits from methanolic leaf fraction of Ficus exasperata Vahl: integrative biochemical, molecular, and computational discovery against bisphenol toxicity

Bisphenol A (BPA) toxicity remains a global health concern, with exposure risks exacerbated in Africa due to limited regulatory enforcement and public awareness. Plant-derived bioactive compounds offer a cost-effective strategy to mitigate BPA toxicity. Here, we integrated bioche...

Risk of Bias Associated with Varying Sampling Strategies for External Comparator Cohorts for Single‐Arm Trials: Insights from Aggressive Lymphoma

Marketing authorizations for oncology drugs are often based on single-arm trials (SATs), and real-world data-based external comparator cohorts (ECCs) are increasingly explored to contextualize results. In retrospective studies, comparators may be identified by time of diagnosis b...

Temperature, pH and silica as key drivers of papillae formation in Mallomonas (Chrysophyceae) across local and continental scales

Abstract Papillae are small siliceous protuberances occurring on the scales and cysts of many chrysophyte algae, yet the environmental factors shaping their distribution remain poorly understood. We combined pan-European and local datasets to identify the key drivers of papillae...
