Solving the Quaternionic Equation x2 = axb

This paper aims to provide precise formula solutions of the two-sided quadratic quaternionic equation [Formula: see text]. The main method is to introduce an efficient way of eliminating the number of real parameters from [Formula: see text]. By using the Lefschetz fixed point th...

Enhanced Thermal Electromotive Force in Lithiated CoPBA/NiPBA Tertiary Battery

Tertiary batteries (TBs), or thermo-rechargeable batteries, have attracted attention as an energy harvesting technology that utilizes changes in ambient temperature. Prussian blue analogues (A-MPBAs; AxM[Fe(CN)6]y, where A and M are Li+ or Na+ ions and a transition metal, respect...

Confronting Biodiversity Risk: Its Role in Shaping Corporate External Financing Choice

ABSTRACT This paper investigates how biodiversity risk shapes corporate financing decisions. We propose a Financing Hierarchy Distortion framework, arguing that biodiversity risk amplifies information asymmetry and legitimacy costs, thereby pushing firms toward debt‐heavy adjustm...

Neuropsychiatry genetics in Africa

Across Africa, rising mental health needs coincide with rapid advances in genomics, digital health and continental policy reform. Yet research into the genetic, environmental and social determinants of neuropsychiatric illness remains sparse and underfunded. This review argues th...

177Lu-Labeled Ectonucleotide Pyrophosphatase/Phosphodiesterase 3 Monoclonal Antibody-Targeted Therapy for Clear Cell Renal Cell Carcinoma

Abstract Clear cell renal cell carcinoma (ccRCC) remains a therapeutic challenge. Ectonucleotide pyrophosphatase/phosphodiesterase 3 (ENPP3) is highly expressed in ccRCC tissues and cell lines, representing a promising target. This study aimed to conjugate lutetium-177 (177Lu) to...

I casi studio per testare utilità e validità dell'Atlante Aria Salute: definizione del quadro concettuale.

OBJECTIVES: to describe the process of selecting and applying a shared conceptual model for the analysis of case studies designed to test the usefulness and validity of the Air and Health Atlas in supporting decision-making, in its current version and in its potential future deve...

The User Agency Trap in Media Literacy Chatbots: Interactive Evaluation Format, Imperfection Disclosure, and Visual Misinformation Discernment

Although media literacy interventions are increasingly used to counter misinformation, many remain text-centered and non-interactive, limiting engagement during real-time evaluation. This limitation is particularly consequential for visual misinformation, where realistic syntheti...

Tunable Noncovalent Interactions for Stereodivergent Organo/Metal Dual Catalysis: Asymmetric Allenylation of Both 3-Alkyl and 3-Aryl Oxindoles

Abstract The development of advanced catalytic paradigms for the precise synthesis of all stereoisomers of chiral molecules has long been an important yet challenging pursuit. Organo/metal dual catalysis represents a powerful platform for stereodivergent construction of vicinal s...

Sensitivity to ATR–CHK1 pathway inhibition in MDS/AML is enhanced by SRSF2 mutations and reduced by RUNX1 loss

Abstract SRSF2 mutations occur in 5–15% of acute myeloid leukemia (AML) and ~15% of myelodysplastic neoplasms (MDS), are enriched in elderly/secondary AML, and lack mutation-directed therapy. We aimed to identify vulnerabilities in MDS/AML with SRSF2 mutations. Ex vivo drug-sensi...

Calibrated Decisions Are Not Calibrated Probabilities: An Exact-Target Audit of Jev and Three Open Decision Models

Decision models answer typed questions with probabilities instead of text, and their main selling point is that those probabilities can be trusted. TypeSafe says its Jev model, trained with an unpublished method called Reinforcement Learning for Calibrated Decisions (RLCD), retur...

Post quantum federated authentication framework for Industrial Internet of Things using FALCON threshold signatures and zero knowledge verification

Abstract Distributed authentication techniques enable edge device trust in smart manufacturing and energy infrastructure Industrial Internet of Things contexts. Existing blockchain-based authentication schemes mostly use the elliptic curve digital signature algorithm, which can b...

Structural Cryptanalysis of a Class-2 Nilpotent Lie Algebra Signature Candidate: Linearization and Equivalent-Secret Forgery

This study presents a structural cryptanalysis of a Fiat–Shamir-type digital-signature candidate based on class-2 nilpotent Lie algebras over finite fields. We show that the public transformation is linear in the signing secret and that public-key inversion reduces to a consisten...

CFIR-guided formative implementation research to co-design a supervised toothbrushing programme through Anganwadi centres in Kerala, India

Dental caries remains a major public health concern among preschool children, driven by modifiable behaviours such as inadequate toothbrushing and poor oral health practices. Anganwadi Centres are community-based centres within India’s Integrated Child Development Services (ICDS)...

Strong Gravitational Lensing by Lorentzian-Euclidean Black Hole

We investigate the strong gravitational lensing properties of the Lorentzian Euclidean black hole, a spacetime in which the horizon at [Formula: see text] is not a coordinate singularity but a genuine surface of signature change, with the associated curvature singularities remove...

SSTR Expressing Tubercular Bony Lesions in a Patient with Suspected Metastatic Pheochromocytoma

We report a case of a 38-year-old male with biochemically confirmed pheochromocytoma and somatostatin receptor (STIR)-expressing adrenal and skeletal lesions. Discordant findings on functional imaging, along with lytic bone lesions, raised the suspicion of an alternate aetiology....

A Reversibly Cross‐Linked Network Enables Spider‐Silk‐Like Strain‐Adaptive Mechanical Behavior and Low‐Temperature Tolerance in Artificial Fibers

ABSTRACT Replicating spider‐silk‐like strain‐adaptive mechanical behavior remains challenging because elasticity, rapid stiffening, and energy dissipation must be sequentially activated across distinct deformation regimes. Here, we reproduce this behavior in reversibly cross‐link...

Semitransparent Quasi-2D Dion–Jacobson Layered Perovskite Films for Indoor Photovoltaics

Abstract Semitransparent indoor photovoltaics (IPVs) based on layered perovskites offer opportunities for integrated energy harvesting, yet their structural understanding and implementation remain limited. Here, we report the first demonstration of semitransparent thin-film photo...

A Mass-Conserving Spatiotemporal Graph ODE Model for Multi-Step Streamflow Forecasting in a Sparsely Gauged Semi-Arid Basin

Semi-arid loess basins in the middle Yellow River have rapid runoff responses, short hydrological memory, and sparse gauging networks, so pooled metrics across all stations can conceal forecast failures in low-flow tributaries and during dry periods. This study proposes DaSTGODE,...

Loss of RafE impairs raffinose utilization and increases early pneumococcal burden in mice

ABSTRACT Streptococcus pneumoniae (the pneumococcus) is one of the most common bacterial causes of middle ear infections (otitis media) in children. These infections are highly prevalent but can be persistent and challenging to treat. The pneumococcus is a highly genetically dive...

Investigation of Fluid-Mechanical Interfaces (FMIs) for the Transmission of Oscillations in Hydraulic Fluid

This study investigates fluid-mechanical interfaces (FMIs) for transmitting pressure oscillations in a hydraulic fluid to a piezoelectric stack, with the aim of supporting self-powered sensing and energy harvesting in hydraulic systems. A hydraulic test rig was employed in which...
