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 TypeSafe says its Jev model, trained with an unpublished method called Reinforcement Learning for Calibrated Decisions (RLCD), retur...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...

The impact of perceived fairness on consumers’ willingness to pay for water quality improvements: evidence from China

Financing drinking water improvements in low tariff regimes requires price increases, yet affordability alone cannot ensure public acceptance. In a survey experiment with 1027 urban Chinese residents, perceived fairness is associated with 0.58–0.84 RMB/m3 higher WTP for cleaner r...

A Deterministic Closed-Loop Pipeline for Real-Time Gravitational Wave Parameter Extraction: Forensic Inversion, Kerr Spectroscopy, and GWTC-1 Verification Suite

A Deterministic Closed-Loop Pipeline for Real-Time Gravitational Wave Parameter Extraction This Zenodo repository provides the complete, autonomous, and fully deterministic gravitational wave analysis pipeline designed to extract binary black hole (BBH) coalescence parameters dir...

Development and Validation of a Needs Assessment Guide for mHealth-Based Self-Management among Patients with Hypertension

Background Given the significant global burden of hypertension and the need to understand patients’ self-management needs, preferences, and barriers when developing mobile health (mHealth) interventions, this study aimed to develop and validate a Focus Group Discussion (FGD) guid...

Promoting Statistical Methods to the Members of the Econometric Society: Walter Andrew Shewhart and Statistical Quality Control

Abstract Walter Andrew Shewhart was an American physicist, regarded as a pioneer of statistical quality control (SQC)—an approach to production inspection based on statistical methods, especially sampling theory. He developed SQC in the 1920s while working at the Bell Telephone L...

The limits of Antarctic conservation governance

Abstract The Antarctic region exerts a profound influence on the Earth system, making its conservation fundamental to sustaining planetary health and human wellbeing. The Antarctic Treaty System (ATS) holds near-exclusive authority for environmental protection across the region,...

GSTT2 Switches from a Homeostatic Antioxidant to a Cell-Cycle-Coupled Factor in Therapy-Resistant Esophageal Adenocarcinoma

Background/Objectives: Glutathione S-transferase theta 2 (GSTT2) is highly expressed in esophageal tissues from African American (AA) compared with European American (EA) individuals, but its localization, regulation, and relevance to esophageal adenocarcinoma progression remain...

A genetic algorithm–optimized EWMA control chart integrating machine learning-based risk prediction for multistage thyroid cancer treatment monitoring

Effective monitoring of thyroid cancer treatment requires timely detection of clinically meaningful changes across complex, multistage care pathways. Traditional monitoring approaches often rely on static thresholds and periodic assessments, limiting their sensitivity to subtle y...

Genomic analysis of phosphate-solubilizing bacteria Enterobacter ludwigii I42 and its impact on maize growth

Phosphorus (P) is an essential macronutrient required for optimal plant growth, yet its limited bioavailability in soil often restricts crop growth and yield. Phosphate-solubilizing bacteria (PSB) have the capacity to convert insoluble inorganic and organic P into forms readily a...
