Human evolution and the obstetrical dilemma: The pelvic floor hypothesis

open access: yesThe Anatomical Record, EarlyView.
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.

Enhanced optimisation of MPLS network traffic using a novel adjustable Bat algorithm with loudness optimizer

open access: yesResults in Engineering
The increasing dependency on network connectivity necessitates superior network performance, characterized by continuous availability and high reliability. Multiprotocol Label Switching (MPLS) networks have emerged as a robust solution to the limitations

Updated COVID‐19 Vaccines and Health Outcomes in Patients With Autoimmune Rheumatic Conditions

open access: yesArthritis &Rheumatology, EarlyView.
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

open access: yesTehnički Glasnik, 2022
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.

Higher risk of Long COVID among patients with autoimmune rheumatic diseases and immunomodulatory therapy: a retrospective cohort analysis of national US data.

open access: yesArthritis &Rheumatology, Accepted Article.
Background Little is known about the prevalence of and factors associated with Long COVID in patients with autoimmune rheumatic diseases (AIRDs). Methods We conducted a retrospective cohort study using data from the National Clinical Cohort Collaborative (N3C).

Data, not documents: Moving beyond theories of information‐seeking behavior to advance data discovery

open access: yesJournal of the Association for Information Science and Technology, Volume 76, Issue 4, Page 649-664, April 2025.
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.

Developing a critical caste analysis within information science and technology: A research review: An Annual Review of Information Science and Technology (ARIST) paper

open access: yesJournal of the Association for Information Science and Technology, EarlyView.
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.

The ultimate forgery: A semiotic deconstruction of large language models as engines of simulated selfhood

open access: yesJournal of the Association for Information Science and Technology, EarlyView.
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]

open access: yes, 2018
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.
