Vibration characteristics analysis and vibration suppression of shaft system based on multivariate nonlinear factors

Shale-gas reciprocating-compressor shaft systems are subject to coupled bending-torsional vibration produced by alternating loads and interacting nonlinearities, which challenges reliable vibration prediction and safety-oriented design. This study proposes a unified multi-nonline...

Odd perfect numbers have a prime factor exceeding 10^9

We prove that every odd perfect number is divisible by a prime exceeding 10^9, improving the bound 10^8 of Goto and Ohno. The proof follows the method of Hagis and Cohen, Jenkins, and Goto and Ohno. Its computational part is organised so that every intermediate claim is either an...

Chronicling Inequity: 25 Years of Racial and Ethnic Politics Scholarship in SPPQ

Abstract In this review essay, we discuss what State Politics and Policy Quarterly has taught us about racial and ethnic politics (REP). After discussing the challenges associated with studying REP, we provide three different approaches to illuminate what extant studies have taug...

Evaluating the Canadian Occupational Performance Measure in Acute Rehabilitation: A 25-Year Retrospective Review

Tax Avoidance and Corporate Governance: Mapping the Intellectual Structure, Emerging Trends, and Future Research Frontiers

In spite of a considerable amount of attention being paid to the interaction between tax avoidance and corporate governance across the globe, this study aims to provide a detailed bibliometric evaluation concerning the productivity, performance, and intellectual structure of scie...

High Prevalence and Clinical Burden of Bleeding Disorder of Unknown Cause in Adolescents With Heavy Menstrual Bleeding: Application of New Definition by the International Society on Thrombosis and Haemostasis

BACKGROUND: Bleeding disorder of unknown cause (BDUC) is increasingly recognized in patients with clinically significant bleeding despite normal haemostatic testing. The International Society on Thrombosis and Haemostasis (ISTH) recently proposed a standardized definition incorpo...

A class of efficient linearly implicit methods based on TASE operators for Volterra integral equations

Abstract This paper presents a family of numerical methods for the solution of Volterra integral equations of the second kind. The proposed approach combines a class of Runge–Kutta methods for ordinary differential equations with TASE operators, backward differentiation formulas,...

Maltreatment by Parents and Cyber Deviance Among Adolescents in Taiwan: The Mediating Role of Impulsivity

ABSTRACT Maltreatment by parents is associated with delinquent behaviors in adolescence, sparking various theoretical explanations. However, whether these explanations of offline delinquency are applicable to cyber deviance remains unclear. Guided by the control model of criminal...

Angle-Quantized Spacetime Circulation Around Rotating SMBHs: An Effective Field-Theoretic Framework for Angular Sector Structure and Emergent Mass Hierarchies

Abstract This preprint presents a phenomenological effective field-theoretic framework for investigating angular structure around rotating supermassive black holes. A real scalar order parameter with a symmetry-breaking quartic potential, non-minimal curvature coupling, and Yukaw...

Metabolising microbes, meaning and modernity

Abstract Spanning the body’s interior and its surrounds, the microbiome presents a fruitful site for challenging modernist notions of discretely embodied individuality, bodily impermeability, and the anthropocentrism of much Western thought. Attending to the microbiome, and the g...

Persistent Mn 3+ Sites on Reduced MnO Enable Efficient Syngas Conversion

ABSTRACT Mn‐based materials are widely used for syngas conversion, where MnO is generally regarded as the catalytically active phase under reducing conditions. Yet catalysts derived from different Mn oxide precursors often exhibit markedly different performances despite evolving...

Conditional Identifiability and Inference for OFT-Derived VGM Measurement Predictions: Nuisance Geometry, Calibration, and an Exact Gaussian Benchmark

This paper develops a conditional inverse-analysis layer for OFT/VGM measurement predictions, following the forward-response framework of VGM XIV. It distinguishes equality of observation laws from equality of mean readouts, joint-parameter equivalence from nuisance-family overla...

Behavioral Heterogeneity and the Evolution of Financial Decision-Making in Contemporary Markets

This paper examines the relationship between investor behavior, market volatility, and financial decision-making by synthesizing recent contributions from behavioral finance, household finance, market microstructure, sustainable investment, and digital finance. The literature sho...

Phi‑Modulated E8 Phonon Edge States for Topological Quantum Memory — E8 Intelligence Research

By embedding the 132 Hz harmonic basis into the 240 E8 root vectors and applying phi‑scaled phase locking, a set of symmetry‑protected edge phonon modes emerges along the 8‑dimensional facets of the root lattice. These modes inherit a topological invariant derived from the Dedeki...

Integrated Household Environmental Health Conditions and Their Independent Predictors in an Urban Nigerian Community: A Community-Based Cross-Sectional Study

Household water, sanitation, waste management, food hygiene and housing conditions interact to shape environmental health risks. This study assessed these domains together and identified independent predictors in an urban Nigerian community. A community-based cross-sectional surv...

Species-dependent effects of tool geometry and machining parameters on surface roughness during longitudinal up-milling of Mongolian Scots pine and white oak

Previous studies on wood milling have mainly examined individual species or restricted machining conditions, leaving uncertain whether responses to tool geometry and cutting parameters are transferable across anatomically contrasting woods. This study aimed to distinguish common...

Reactive molecular dynamic simulation of water induced iron corrosion and its prevention mechanism

Corrosion of iron and mild steel in water and in chloride media is a costly problem for industry, and it also raises safety concerns. Organic molecules containing heteroatoms are commonly used to control it. In most of the reported work, though, the electronic structure of the in...

Numerical Investigation of Suspension Heating for Solid Particles

With the global energy transition and large-scale renewable integration, thermal power units are shifting from base-load to peak-shaving roles, but deep peak shaving may cause combustion instability and increased emissions. High-temperature solid-particle thermal storage offers a...
