Global agriculture shows limited evidence of a pollinator-driven yield decline to date

BACKGROUND: During recent decades, declines in the abundance and diversity of wild pollinators have been widely documented, largely driven by human-induced disturbance, such as agricultural expansion, land-use change, pesticide use, invasive species, urbanization, and climate cha...

Gauge Group Structure Theorem, Direct Product Theorem, and the Three-Generation Proposition— The Inevitable Emergence of SU(3)×SU(2)×U(1) from Regime Boundaries and the Topological Constraint on the Number of Heavy Quarks(III)

Building on the empirical findings and mathematical theorems of the previous two papers, this paper completes the theoretical derivation of the gauge group structure of the Standard Model from the Factor Hierarchy Law. The meta-regime factor (color charge) satisfies three conditi...

The Demotion of Gauge Field Theory, the Theoretical Reconstruction of the Standard Model, and the Five-Layer Axiomatization Structure — Precursor Cascade Asymmetry, the Regime Function of the Higgs Mechanism, the Statistical Correspondence of Virtual States, and the Final Formalization of the Factor Hierarchy Law (IV)

This paper is the concluding piece of the regime audit series on the Standard Model of particle physics, completing three core missions. First, it completes the demotion of gauge field theory — demonstrating that gauge field theory is not the most fundamental framework but rather...

<title>Abstract</title> Purpose To develop and evaluate a machine learning based approach for the interpretation of uroflowmetry in pediatric lower urinary tract dysfunction, aiming to reduce interobserver variability and improve diagnostic consistency while maintaining clinical...

Water Quality Assessment of Surface Water, Groundwater, and Wastewater in Bangui, Central African Republic: Physicochemical Parameters, Trace Metal Distribution and Microbial Contamination

Rapid urbanization and inadequate sanitation infrastructure threaten water security in many sub-Saharan African cities. This study presents the first integrated assessment of groundwater, surface water, and wastewater quality in Bangui, Central African Repub-lic, using physicoche...

A Chromosome-level Genome Assembly of the Potato Leafhopper Empoasca fabae (Hemiptera: Cicadellidae)

ABSTRACT The potato leafhopper, Empoasca fabae (Harris, 1841), is a highly polyphagous, migratory insect pest of eastern North America that feeds on more than 200 herbaceous and woody plant species, causing substantial losses to forage and field crops. Despite its agricultural an...

Strange Region Discovery, Precursor Cascade, and the Transition Zone Width Theorem— Four-Tool Cross-Validation, Cascade Asymmetry Confirmation, and Mathematical Proof of the Switching Type Dichotomy(II)

Building upon the discovery of the charm and bottom regime-switching centers in Paper 14, this paper further discovers the strange region (~1.4–1.6 GeV) as the third confirmed regime center. Four tools — ICSS, MOSUM, Chow, and Bai-Perron — provide cross-validation of the strange...

Regime Audit of the Standard Model of Particle Physics by the Factor Hierarchy Law— Activation Operators, Dual-Center Regimes, and Precision Locking of Charm/Bottom Quark Thresholds (I)

Is the Standard Model truly "one model"? This paper uses the Factor Hierarchy Law and Testability Norms to perform a zero-presupposition regime audit on 275 particles from the Particle Data Group (PDG) 2025 public dataset. Exhaustive testing automatically selects Mass + Spin + Is...

The Reduction of Universality: A Regime Boundary Theory for Finite-System Phase Transitions—Cross-Model Evidence for Bimodal Splitting, the Precursor Regime Boundary, and the Tool-Dependence Theorem

Central proposition: Traditional universality is a mathematical convergence artifact of the thermodynamic limit (L→∞). In real, finite systems, regime boundaries are more fundamental physical quantities than universality classes. Using the Factor Hierarchy Law and the Testability...

Fine-Grained and Flexible Dual Authentication for IoT-Connected Healthcare Sensor Networks

IoT-connected healthcare sensor networks require authenticated and privacy-preserving data exchange among wearable sensors, mobile medical terminals, edge gateways, cloud servers, and medical institutions. Existing authentication schemes for healthcare IoT often bind signatures d...

Double-Peak Splitting: The Hidden Structure of Finite-Lattice Phase Transitions in the 3D Ising Model——Verification of the Factor Hierarchy Law on an NP-Complete System: Double-Peak Splitting, Transition Regime, Piecewise Control Function, and Multi-Regime State

On the L=64 lattice of the 3D Ising model—an NP-complete problem rigorously proven to have no analytical solution—the six functional dimensions of the Testability Norms were applied, achieving the detection and classification of the ferromagnetic-paramagnetic phase transition wit...

Intact Neural and Behavioral Processing of Vocal Emotional Expressions in Men with Autism

Background/Objectives. Human voices convey critical socio-affective information, including emotional states. Although autistic individuals are often reported to show difficulties in processing vocal emotional cues, behavioral findings remain inconsistent. This study aimed to asse...

Recurrent intraoperative asystole induced by tumor manipulation in a cervical vagal schwannoma: a case report

<title>Abstract</title> <bold>Background:</bold> Vagal schwannomas are rare, benign tumors arising from Schwann cells of the vagus nerve. Surgical resection is the mainstay of treatment but carries significant risks, including intraoperative hemodynamic instability due to vagal n...

Quantum Laws of Form: Consolidation, Open Questions, and Extensions

George Spencer-Brown's Laws of Form (1969) proposed that the act of drawing a distinction is the primitive operation from which logic, mathematics, and physics can be constructed. This consolidation paper (v2.0) synthesizes the known quantum-Laws-of-Form correspondences — includi...

Quantum Laws of Form: A Syntactic Foundation for Physics

A synthesis of Spencer-Brown's Laws of Form with quantum foundations, exploring the re-entrant form as minimal observer and the calculus of indications as a native language for quantum measurement.

Information-Theoretic Duality Between Regression Topology and Statistical Mechanics——A Data-Driven Equivalence of the Ehrenfest Classification Validated on the 2D Ising Model as the Physics Cornerstone for the Factor Hierarchy Law

This paper establishes an exact information-theoretic duality between econometric regression topology and statistical mechanics. We demonstrate that an autonomous, data-driven testability norm—grounded in the Factor Hierarchy Law, with the Quadruple Test as its specific implement...

P-S1: Spatial Uniqueness and the Geometric Boundaries of Quantum Information — The Many-Body Correlation Reduction Theorem and Its Seven Corollaries(v1.1)

Abstract:Since its birth, the mathematical framework of quantum mechanics — Hilbert space, state superposition, unitary evolution — has been treated as the fundamental postulates of mainstream physics. This has led to a situation lasting nearly a century: quantum mechanics yields...

Regulation of Extracellular HMGB-1 Alarmin Levels by CIGB-300 Anticancer Peptide In Vitro and In Vivo

HMGB-1 is an alarmin representative of DAMP playing a central role in immunogenic cell death (ICD), a necessary condition in the dialog established between dying tumor cells and the immune system during some anticancer therapies. Therefore, early screening for ICD inducers repres...

Using Cadastral Information to Support Forest Owner Aggregation in Small-Scale and Fragmented Forest Ownerships: A Network Analysis Approach in the Forest Sharing® Platform
