Human evolution and the obstetrical dilemma: The pelvic floor hypothesis
Abstract Human childbirth is mechanically difficult because a large‐headed, broad‐shouldered fetus must pass through a comparatively narrow, twisted bony birth canal. Traditional explanations of this “obstetrical dilemma” emphasize the role of bipedal locomotion in inhibiting the evolution of a wider, more spacious pelvis.

Updated COVID‐19 Vaccines and Health Outcomes in Patients With Autoimmune Rheumatic Conditions
Objective We aimed to assess the association between COVID‐19 vaccination status and COVID‐19‐related hospital admissions, need for mechanical ventilation or extracorporeal membrane oxygenation (ECMO), and death in people with autoimmune rheumatic conditions. Methods We conducted a retrospective cohort study using National Clinical Cohort Collaborative

A Lévy Flight Based BAT Optimization Algorithm for Block-based Image Compression
Many metaheuristics have been adopted to solve the codebook generation problem in image processing. In this paper, the Bat algorithm is combined by the Lévy flight distribution to find out the global optimum codebook.

Abstract Many theories of human information behavior (HIB) assume that information objects are in text document format. This paper argues four important HIB theories are insufficient for describing users' search strategies for data because of assumptions about the attributes of objects that users seek.

Abstract Caste—an ascriptive social hierarchy in South Asia and its diaspora—is a globalized phenomenon. Recent caste‐based discrimination, particularly in technology companies and anti‐caste efforts to address it, has compelled academia, policy, and the technology industry to better understand contemporary mechanics of caste.

Abstract Information science rests on a compact: its mediating signs maintain a traceable relation to what they describe. Large language models (LLMs) break it architecturally, generating discourse that is statistically plausible yet epistemically ungrounded, while standard metrics (precision, recall, relevance) cannot detect the rupture.

Bat Algorithm with Individual Local Search [PDF]
Bat algorithm (BA) is a well-known heuristic algorithm, and has been applied to many practical problems. However, the local search method employed in BA has the shortcoming of premature convergence, and does not perform well in early search stage. To avoid this issue, this paper proposes a new update method for local search.
