Chebyshev Spectral Collocation with an Exact Operational Integration Matrix for Nonlinear Volterra–Hammerstein Equations

This paper proposes a Chebyshev spectral collocation method for nonlinear Volterra–Hammerstein integral equations of the second kind with smooth kernels. We approximate the unknown solution using a finite Chebyshev expansion and place collocation points at the Chebyshev–Gauss–Lob...

Computational investigation on combustion efficiency in jet engines using Lagrangian method

Abstract Multiphase fuels, such as liquid fuels with dispersed nanoparticles or secondary phases, exhibit complex interactions involving atomization, evaporation, turbulence, and heat transfer. In particular, the size of fuel droplets significantly influences combustion character...

Genomic prediction of antimicrobial resistance in priority healthcare pathogens using Staramr

ABSTRACT Treatment of healthcare-associated infections is becoming increasingly challenging due to rising antimicrobial resistance (AMR). As clinical microbiology and public health continue to transition toward whole-genome sequencing (WGS) for outbreak detection, diagnostics, an...

Tripartite Coxeter Harmonic Locking of Dark Matter to 360-Day Cycles — E8 Intelligence Research

The 240 roots of E8 distribute across the three MUL.APIN cosmological paths (Anu/Enlil/Ea) as 80 roots per path, with each path's 30 Coxeter planes (10 planes × 3-fold symmetry) acting as harmonic mirrors that confine dark matter standing waves to quantized celestial zones. The 1...

Product innovation and process innovation: differentiated organizational outcomes in brick-making companies in the Global South

Purpose The purpose of this paper is to determine how product and process innovation influence profits, productivity and the expansion of goods or services in brick-making companies in the Global South. Design/methodology/approach This study adopts a quantitative approach with a...

A Critical Analysis of Barriers to Practical Training and Exercising in UK Fire Service Control Rooms: Evidence‐Informed Recommendations for Enhanced Operational Preparedness

ABSTRACT Persistent weaknesses in training for UK Fire and Rescue Service control rooms may undermine operational preparedness, despite their critical role in emergency response. Public inquiries and inspections repeatedly highlight inconsistent, underdeveloped training provision...

Racial and Ethnic Disparities in the Utilization and Outcomes of Catheter Ablation for Atrial Fibrillation and Flutter: a State-of-the-Art Review

Abstract Purpose of Review Catheter ablation (CA) has become a first-line option for rhythm control strategy for atrial fibrillation (AF) and atrial flutter (AFL). We synthesize recent evidence regarding racial and ethnic disparities in CA utilization in the United States and exa...

Fuzzy MICMAC-Based Study of Barriers to Industry 4.0 and Lean Six Sigma Integration in Indian Smart Manufacturing

ABSTRACT The integration of Industry 4.0 (I4.0) technologies with Lean Six Sigma (LSS) has emerged as a promising approach for enhancing operational efficiency, flexibility, and resilience in modern manufacturing systems. Despite its potential benefits, organizations continue to...

Transformational leadership and service innovation performance: the role of knowledge sharing and innovation culture in the hospitality sector employees

Abstract This research examines how Indian hotels can systematically create “wow” moments for guests by translating transformational leadership (TL) into frontline employees’ service innovation performance (SIP) rather than treating innovation as ad hoc or leader‑driven in a vacu...

ICER-Controlled inhibitory plasticity of amygdala engram neurons regulates fear memory precision

Abstract Fear discrimination—the ability to distinguish threatening stimuli from non-threatening ones—is an essential adaptive behavior, yet the neural mechanisms underlying individual differences in discrimination precision remain unclear. Here, we show that parvalbumin-positive...

The State-Dependent Coefficient Matrix (SDCM) Architecture

Traditional numerical mechanics relies on continuous calculus and sequential differential solvers (such as Runge-Kutta or Crank-Nicolson) to model non-linear systems, inherently introducing artificial computational latencies, floating-point truncation traps, and the strict barrie...

Rapid Whole Genome Sequencing Enhances Pediatric Cancer Diagnosis

Abstract Whole-genome sequencing (WGS) has been shown to improve diagnosis beyond standard-of-care genetic tests and guide precision treatment for childhood cancer. While WGS is now offered for children with suspected cancer in England, clinical workflows typically return results...

Ultrasensitive Electrochemiluminescence Aptasensor With DNA Nanotetrahedron Amplification for Multilevel Detection of cTnI From Cells to Patients

ABSTRACT Accurate detection of myocardial injury (MI) biomarkers for assessing anticancer drug‐induced cardiotoxicity has long been constrained by insufficient capture efficiency and limited assay sensitivity. To address this challenge, we developed an electrochemiluminescence (E...

Palladium-Catalyzed Enantioselective Dearomative Domino Heck/Stille Reaction of Indoles

Abstract Palladium-catalyzed enantioselective dearomative difunctionalization of N-substituted indoles was developed via dearomative carbonpalladation and subsequent capture of benzyl-Pd species by organostannane reagents (domino Heck/Stille reaction). A wide range of 2,3-disubst...

Effect of different cariostatic agents on the surface roughness and color change of CAD–CAM‐milled restorative materials: An in vitro comparative study

Abstract Purpose To evaluate the influence of different cariostatic agents: 38% silver diamine fluoride (SDF), 38% SDF + potassium iodide (RS), and nano silver fluoride (NSF) compared with distilled water (control), on the surface roughness and color change of CAD–CAM‐milled rest...

Autosomal Recessive RDH12-Leber Congenital Amaurosis Retinal Organoids Suggest Phospholipid Pathway Dysregulation

NADPH-dependent retinol dehydrogenase 12 (RDH12) reduces all-trans-retinal in photoreceptor inner segments to regulate the phototransduction cascade and control the concentration of retinoids in the retina. Variants in RDH12 have been reported to cause an array of retinal disease...

The Effect of Broiler-Targeted Lighting Programs on Productivity, Health, and Welfare

Background: Poultry are highly sensitive to lighting photoperiod, intensity, and color, yet little research has combined these components into a single broiler-targeted lighting program. This study evaluated an integrated dynamic LED lighting program and a further red-light dawn/...

Corrosion–Fatigue Damage Characteristics and Evolution Mechanisms of Failed Sucker Rods

Sucker rods operate under long-term cyclic loading while being exposed to produced fluids, making corrosion–fatigue damage an important integrity concern in rod-pumped wells. This study applied a field-scale multi-source evidence framework to produced-fluid samples from 16 sucker...

Topological Insulators: Z₂ Invariant, Dirac Edge States, and Disorder-Driven Transitions — E8 Intelligence Research

FINDING: Topological insulators are bulk-insulating materials with symmetry-protected conducting edge/surface states, characterized by a topological invariant (Z₂ index) rather than local order parameters. | MATH: Z₂ topological invariant (ν = 0 or 1) for time-reversal-invariant...

The Growing Role of Evaporative Demand in Driving Record‐Breaking Droughts in the Amazon Basin

Abstract Amazon droughts have historically been driven by precipitation deficits, but recent escalating drought events highlight a regime shift toward “hot droughts.” By decomposing historical drought drivers (1979–2024), we show that rising evaporative demand (represented by pot...
