Effect of Corrosion-Induced Structural Degradation on the Ultimate Strength of a High-Tensile-Steel Ship Hull

Standard structural assessments of ship hulls include the evaluation of the elastic structural response. Elastic analysis neglects extreme and unpredicted loadings, which can produce catastrophic outcomes, such as the loss of the ship’s ultimate strength. Moreover, hull elements are considered unaffected by age-related degradation. Therefore, this study models and quantifies the effect of corrosion-induced structural degradation on the ultimate strength of a high-tensile-steel (HTS) cargo ship using...

QAnon and the Epistemic Communities of the Unreal: A Conceptual Toolkit for a Sociology of Grassroots Conspiracism

The messy politics of combating the COVID-19 pandemic, compounded by the confusion caused by the global (dis)infodemic, have propelled conspiracism from the fringes of society into the public mainstream. Despite the growing political impact of digitally enabled conspiracy theories, they are predominantly delegitimized on three fronts – as psychopathology, pseudoscience, and/or parapolitics. In contrast, this article employs three non-pathologizing conceptual counteroffers borrowed from critical...

Beyond the office walls: Work design configurations for task performance across on‐site, hybrid and remote forms of work

AbstractDespite alternative work arrangements becoming more prevalent, existing work design approaches are mostly based on research and practice of traditional on‐site work. Struggles with capturing employee performance are reported across different off‐site, non‐traditional forms of work, such as remote and hybrid. This article performs a comprehensive fuzzy set qualitative comparative analysis to juxtaposing different configurations of job characteristics across forms of work. Our multi‐source...

A bivariate distribution with generalized exponential conditionals

Abstract In this work, we construct a new bivariate statistical distribution by the conditionally specified model approach. The conditional distributions follow the well-known generalized exponential distribution which includes the ordinary exponential distribution and is more flexible than gamma and Weibull in some ways. The newly defined distribution has four parameters that increase the flexibility of the model in data fitting. By equating the dependence parameter to zero, the...

Phase holonomy underlies puzzling temporal patterns in Kuramoto models with two sub-populations

We present a geometric investigation of curious dynamical behaviors previously reported in Kuramoto models with two sub-populations. Our study demonstrates that chimeras and traveling waves in such models are associated with the birth of geometric phase. Although manifestations of geometric phase are frequent in various fields of physics, this is the first time (to our best knowledge) that such a phenomenon is exposed in ensembles of Kuramoto oscillators or, more broadly, in complex systems.

New Approaches Based on Inflammatory Indexes in the Evaluation of the Neoplastic Potential of Colon Polyps

Colorectal polyps, precursors to colorectal cancer (CRC), require precise identification for appropriate diagnosis and therapy. This study aims to investigate the differences in hematological and inflammatory markers, specifically the CALLY index, HALP score, and immuno-inflammatory indexes, between neoplastic and nonneoplastic polyps. A retrospective cross-sectional study was conducted on 758 patients aged 61.0 ± 11.8 who underwent polypectomy between June 2021 and May 2024. Patients with colorectal...

Möbius group actions in the solvable chimera model

We study actions of Möbius group on two sub-populations in the solvable chimera model proposed by Abrams et al. Dynamics of global variables are given by two coupled Watanabe–Strogatz systems, one for each sub-population. At the first glance, asymptotic dynamics in the model seem to be very simple. For instance, in the stable chimera state distributions of oscillators perform a simple rotation after a certain (sufficiently large) moment. However, a closer look unveils that dynamics are subtler...
