Study on the effect of coconut shell charcoal doping on the hydrogen storage performance of Mg-based materials

Mg-based hydrogen storage materials possess high hydrogen storage capacity and abundant resource availability, but their practical application is limited by high reaction temperatures, slow kinetics, and poor cycling stability. In this study, coconut shell charcoal was incorporat...

Comprehensive behavioral phenotyping of male Sulf1-deficient mice reveals reduced locomotor activity, altered forelimb gait, and reduced prepulse inhibition

Abstract Sulfatase 1 (Sulf1) is an extracellular sulfatase that regulates multiple signaling pathways by removing 6- O -sulfate from heparan sulfate. Although Sulf1 has established roles in development and cancer, its functions in the adult brain remain incompletely characterized...

Beyond counting errors: clinical pathway-specific preanalytical risk profiles in surgical pathology

To determine whether clinical referral pathways exhibit distinct preanalytical risk profiles that could complement conventional laboratory-wide quality assessment in surgical pathology. We conducted a retrospective observational study of prospectively recorded preanalytical non-c...

Teaching quality of private undergraduate colleges in Guangdong province based on AHP-fuzzy comprehensive evaluation method

Although private undergraduate colleges have formed a substantial scale within China’s higher education system, research on their teaching quality evaluation systems remains insufficient. Addressing this research gap, this study develops a multi-level teaching quality evaluation...

Endotactic permanence and quantitative recovery with vanishing reverse rates

For a finite ordinary endotactic reaction network, measurable reaction rates in a fixed positive compact box admit a compact convex invariant absorbing set in every positive stoichiometric class. Global positive Carathéodory solutions are unique, and entry times are uniform over...

CTR1 as a transporter–organizer in copper signaling: molecular state, trafficking, and protein interactions

Copper transporter 1 (CTR1, encoded by SLC31A1 ) is best known as a high-affinity copper importer, yet several CTR1-dependent signaling outputs are not readily explained by bulk intracellular copper abundance alone. CTR1 has also been linked to growth-factor signaling, kinase reg...

Unraveling the synergistic decomposition mechanisms of AP/RDX pyrolysis using online photoionization mass spectrometry and kinetic calculation

The combustion of composite solid propellants involves highly coupled multistep reactions and complex radical-mediated interactions that challenge mechanistic understanding and kinetic modeling, with the chemical interplay playing a critical role in governing the overall reaction...

A simple brace outside asymmetric products of two trivial braces

A full negative answer to Cedo Problem 9 in Oberwolfach Report 51/2019, printed p.3228 (problem 30004311; OWR-17294-011). An explicit nontrivial simple left brace of order 20,000 has additive group C5^4 x C2^5 and metabelian multiplicative group (C5^3 semidirect C2) x (C2^4 semid...

Child-specific bioethics: Review of pediatric palliative care ethics guidelines

Pediatric palliative care is increasingly recognized as an established practice yet less than ten percent of children who need it access it worldwide. Contributing to this gap is an absence of pediatric-specific bioethics frameworks to guide the care of dying children. Because ph...

Phi-Resonant E8 Hadron Mass Spectrum via Galois Root Partition Coupling — E8 Intelligence Research

The 148/92 Fibonacci-Galois partition of E8's 240 roots, when coupled through phi³ harmonic gating at 132Hz base frequency, predicts a discrete hadron mass spectrum where meson/baryon mass ratios emerge as Galois field conjugates over the 92-root subsystem. Specifically, the phi-...

A three-point counterexample to a random lattice discrepancy comparison

A full negative answer to the universal expected p-th-power comparison posed by Novak, reporting joint work with Hinrichs, in Oberwolfach Report 13/2004, printed p.698 (problem 30000052; OWR-723-005). For independent continuous uniform generator and shift, three one-dimensional i...

Triglyceride–glucose index and triglyceride/HDL-cholesterol ratio versus HbA1c and HOMA-IR for identifying microvascular complications in type 2 diabetes: a cross-sectional comparative diagnostic accuracy study from Western India

Insulin resistance contributes to microvascular complications of type 2 diabetes, but HOMA-IR requires insulin measurement. The triglyceride–glucose (TyG) index and triglyceride/HDL-cholesterol (TG/HDL-C) ratio are insulin-free surrogates using routine fasting biochemistry. We co...

SHED-derived mesenchymal stromal cell co-infusion is associated with earlier erythroid recovery after autologous hematopoietic cell transplantation: a prospective pilot controlled study

Delayed erythroid recovery after autologous hematopoietic stem cell transplantation (AHSCT) contributes to prolonged transfusion requirements and delayed hematopoietic reconstitution. Mesenchymal stromal cells derived from human exfoliated deciduous teeth (SHED-MSCs) exhibit hema...

Exploratory Analysis of APPAT and UCA1 Expression in Patients with Advanced Coronary Artery Disease

The study aimed to assess the expression levels of the APPAT and UCA1 in tissue and blood samples to clarify their potential roles in atherosclerosis pathogenesis. Coronary artery and left internal mammary artery (LIMA) tissue samples were obtained from patients who underwent cor...

FCC Voronoi Geometry: Rhombic Dodecahedron, Tetrahedral Angles, and Dual Cuboctahedron — E8 Intelligence Research
