Finite-Horizon Emergence of Curved Lorentzian Readout Geometry in the Balance-Field Equation

This 20-page preprint establishes a constructive finite-horizon geometry theorem for a four-mode, full-persistence sector of the Balance-Field Equation (BFG). An invariant family reduces the complete operator update to a rational eigenvalue recursion with endogenous weights. Four...

Prioritizing Systemic Risk Factors of Substandard Construction in South Korean Apartment Projects Using a Modified Delphi and Risk-Matrix Approach

Recent large-scale collapses at South Korean apartment construction sites have highlighted the need to examine technical and systemic risk factors in an integrated manner. This study identifies and prioritizes expert-perceived systemic risk factors associated with substandard con...

Exercise for depression: strong option with clinical benefits

SUMMARY Exercise, investigated as a treatment option for depression, is promising in that it has previously shown antidepressant effects and is accessible, low-cost and additionally provides physical health benefits. This commentary assesses the effects of exercise interventions...

Assessment of circulating xenin as a potential metabolic biomarker in active smokers

Abstract Objectives Xenin regulates appetite, motility, and metabolic homeostasis. As the link between smoking and xenin has not yet been sufficiently investigated, this study compared serum levels between smokers and non-smokers and evaluated their associations with metabolic, h...

Improving Molecular Formula Assignment of Nitrogen- and Sulfur-Rich DOM in Ultrahigh-Resolution Mass Spectrometry: Validation of Oligopeptides

Abstract Molecular formula (MF) assignment in ultrahigh-resolution mass spectrometry (UHRMS) analyses of dissolved organic matter (DOM) containing multiple non-oxygen heteroatoms (e.g., nitrogen and sulfur) is highly environmentally relevant yet remains challenging. Recent studie...

Effects of Insecurity and Governance Quality on Economic Growth in Nigeria

This study examined the effects of insecurity and governance on economic growth in Nigeria over the period 2002–2024. The study focused on terrorism incidence, terrorism injuries, terrorism fatalities, military expenditure and political instability as explanatory variables while...

A Sharp Three-Fifths Bound for Seymour Vertices in Three-Regular Oriented Graphs

Let D be a finite simple oriented graph with indegree and outdegree three at every vertex. A Seymour vertex has at least as many exact second out-neighbors as first out-neighbors. We prove that at least ceil(3|V(D)|/5) vertices are Seymour vertices. If B is the set of the remaini...

Modeling the Relationship Between Ride-Hailing Demand Density and the Urban Built Environment on the Basis of the GNNWR and Dynamic Spatial Partitioning

Understanding the complex spatiotemporal heterogeneity between ride-hailing demand and the urban built environment is crucial for optimizing urban space and allocating transportation resources. Previous analyses using fixed spatial scales (e.g., regular grids or administrative bo...

Hexacatenar Columnar Liquid Crystals with a Perfluoronaphthalene-Core: Synthesis, Self-Organization, Charge Transport and Photoluminescence

Abstract Columnar liquid crystals featuring one-dimensional charge transport and self-assembly are of considerable interest for organic electronic applications such as organic field-effect transistors (OFETs) and organic light-emitting diodes (OLEDs). Fluorination emerges as a po...

Analyzing the cultural landscape of Chinese art districts through online social media: a text mining and theoretical interpretation using user-generated content

The study examines three Chinese art districts, namely Beijing 798, Hangzhou Xiangshan Art Commune, and Jingdezhen Taoxichuan, using 28,661 social media posts. By integrating semantic networks, irony-aware sentiment analysis, and LDA (Latent Dirichlet Allocation) modeling. The re...

CLAIR: A Reference-Free Framework for In Situ Defect Detection in Fused Filament Fabrication Using Contra-Lateral Sampling and Inpainting Residuals

Manufacturing defects occur routinely in the fused filament fabrication (FFF) process, and a single undetected failure converts machine time, filament, and operator attention into scrap. This paper presents CLAIR (Contra-Lateral Inpainting Residuals), a reference-free monitoring...

Bone marrow myeloid skewing and preserved immunoregulation in hip osteoarthritis of elderly patients

Abstract Osteoarthritis (OA) is increasingly recognized as a disease involving low-grade inflammation and immune remodeling, yet the contribution of the bone marrow (BM) myeloid compartment to hip OA remains poorly defined. Myeloid-derived suppressor cells (MDSCs) are immature my...

PEEK Pectus Bar: Evaluation of a New Material for Pectus Excavatum Repair in Children and Teenagers

The Nuss procedure for Pectus Excavatum repair has relied on metallic bars for the past 3 decades. The technical efforts have focused on the improvement of stability and the reduction of the associated risks. However, some challenges still remain, like metal ion release, thoracic...

Associations between psychological distress, nutritional attitudes, and oral hygiene behaviors in dental students

Abstract Background This study aimed to investigate the interrelationships between psychological distress, nutritional attitudes, and oral health status among dental students and to evaluate the associations of sociodemographic and lifestyle factors on these parameters. Methods I...

Z₂ Topological Invariants in Time-Reversal Invariant Superconductors via Parity Eigenvalues — E8 Intelligence Research

FINDING: Z₂ topological invariant in time-reversal invariant (TRI) superconductors is defined via a Bloch Hamiltonian mapping, yielding one invariant in 2D and four in 3D, computed from parity eigenvalues at time-reversal invariant momenta (TRIM). | MATH: For a TRI superconductor...
