Rim-driven pumpjet design by optimization

Abstract This paper presents a numerical study based on a Simulation-Based Design Optimization (SBDO) framework for the design of a marine rim-driven pumpjet propulsion system at a prescribed operating condition. The main objective is to compare the hydrodynamic performance of ri...

The Confinement Scale from the Electron Mass and the Fine-Structure Constant: Mutual Entanglement as Channelized Strain

The scale of QCD confinement is an input to the Standard Model, traceable to the measured strong coupling and unrelated to any electromagnetic quantity. This paper derives it from the electron mass and the fine-structure constant alone, σ=N_ch m_e^2 c^3/(ħα^2), where N_ch is an i...

Ethylene Affects Soil Multifunctionality in Maize Rhizosphere by Driving Sensitive Microbial Communities

Abstract Ethylene modulates plant fitness, but its role in rhizosphere soil multifunctionality remains unclear. This study demonstrates that endogenous ethylene suppresses C- and N-cycling functions while promoting organic P mineralization in the maize rhizosphere, ultimately dim...

A Three-Regime Consistency Test of the Enchan Field: CDM-like CMB Persistence, Galactic Low-Acceleration Enhancement, and Solar-System Newtonian Recovery

This record contains the manuscript and complete reproducibility package for “A Three-Regime Consistency Test of the Enchan Field: CDM-like CMB Persistence, Galactic Low-Acceleration Enhancement, and Solar-System Newtonian Recovery.” The study tests whether the Enchan Field can c...

Effects of immersive training on sports perceptual-cognitive skills: A systematic literature review

Immersive training using virtual reality (VR), 360° video, and CAVE environments shows potential for enhancing perceptual-cognitive skills in sports; however, evidence remains limited and methodologies heterogeneous. This systematic review synthesised quantitative controlled inte...

New edge proposed: opening_range_breakout_retest — E8 Intelligence Research

{ "name": "opening_range_breakout_retest", "source": "Linda Raschke / Market Wizards", "type": "entry_engine", "rule": "Enter short when price breaks below the opening range low (first 30 minutes of the session) by 0.25 ATR, then pulls back up to test that low level from below wi...

ESG and firm valuation: causal effects versus predictive relevance

Abstract This study examines the relationship between environmental, social, and governance (ESG) performance and firm valuation, with a particular emphasis on distinguishing between causal effects and predictive relevance. Using a panel dataset of publicly listed firms, the anal...

Penrose Tilings: Aperiodic 5-Fold Symmetry and the Golden Ratio in Quasicrystals — E8 Intelligence Research

FINDING: Penrose tilings are aperiodic, 5-fold symmetric tilings that violate classical crystallographic restrictions, forming the basis for quasicrystal discovery. | MATH: Golden ratio φ = (1+√5)/2 ≈ 1.618; inflation/deflation scaling by φ; 5-fold rotational symmetry forbidden i...

Isothermal Captureand Release of Carbon Dioxide witha Porous Molecular Hexaamine

Abstract The decarbonization of fossil fuel combustion streams and air is imperative to achieve negative carbon emissions and requires discovery of new materials that exhibit high CO2 capacities, long-term stability, and minimal energy input for the release of pure CO2. Numerous...

Does the mother’s cooking skills influence the school-aged child’s adherence to the Mediterranean diet in Turkiye? a cross-sectional study

This cross-sectional descriptive study was designed and conducted to assess the effect of mothers’ cooking skills on school-aged children’s adherence to the Mediterranean diet. The demographic characteristics and anthropometric measurements of 388 mothers and children were collec...

Hematogenous vertebral osteomyelitis caused by vaginal microbiota: metagenomic resolution of a polymicrobial anaerobic case

Abstract We describe a rare case of a 35-year-old female patient suffering from polymicrobial hematogenous vertebral osteomyelitis caused by vaginal microbiota following sexual intercourse. Anaerobic blood cultures yielded Fannyhessea vaginae and Gemelliphila asaccharolytica , an...

Dural Puncture Epidural, Standard Epidural, and No Epidural: Comparative Effects on Labor Progression and Neonatal Outcomes

Objective: To compare non-epidural labor, standard epidural analgesia, and dural puncture epidural analgesia with respect to labor progression, obstetric outcomes, analgesia-related outcomes, and neonatal results. Methods: This single-center retrospective observational cohort stu...

Wear-InducedInterfacial Diffusion in TiN Coatings:A Molecular Dynamics Study

Abstract Understanding the relationship between structural degradation and atomic diffusion is essential for elucidating coating failure at solid interfaces. However, the atomic-scale connection between wear and diffusion remains unclear under coupled thermo-mechanical conditions...

Comparison of local, regional and general anaesthesia on surgical outcomes in arteriovenous fistula creation

Dialysis is essential for patients with end-stage renal disease and arteriovenous fistula (AVF) surgery creates access for high flow dialysis. This review examines the effects of local, regional and general anaesthesia on AVF outcomes, drawing on studies from 2014 to 2024. Region...

The Architecture of Consolidation: Nests of Corporate Control in the Agrochemical Network

ABSTRACT Research on agricultural consolidation tends to equate corporate control with the dominance of a few large firms. We take an alternative approach that examines control through the explosive growth of legally distinct firms that fragment accountability. Using a new global...

Addressing the governance dilemma of urban low value waste under misalignment

Municipal solid waste (MSW) governance has attracted growing global attention. However, low-value waste (LVW) remains a critical bottleneck undermining system-wide performance. Drawing on theories of policy–technology–management alignment and urban environmental governance, this...

Adsorptive removal of crystal violet using chemically activated biowaste: Molecular insights from DFT and molecular dynamics simulations and experimental assessment

In this study, we explore the removal of crystal violet (CV), a cationic organic dye, by adsorption utilizing a biomass-derived material made from date pits, which provides a novel class of cost-effective and efficient adsorbents for CV removal. The synthesized material's structu...

Experimental–numerical investigation of solid–liquid jet erosion in AISI 304 stainless steel: effect of impingement angle and strain hardening

Solid–liquid jet erosion of AISI 304 austenitic stainless steel was investigated at impingement angles of 30° and 45° using a coupled experimental–numerical framework. One-hour slurry jet tests (2 wt% SiO₂, mean particle size 230 μm, velocity 1 m·s⁻¹) were combined with transient...
