Ultrasonographic Evaluation of Achilles Tendon Thickness in the Emergency Department: A Novel Measurement Method

Objective: Increased Achilles tendon thickness is associated with hypercholesterolemia and cardiovascular disease, and ultrasonography is the preferred method for its assessment. This study aimed to evaluate the agreement between Achilles tendon ultrasonographic measurements obta...

Radiographic Changes in Patellar Height Following Rapid Weight Loss After Sleeve Gastrectomy: A Retrospective Observational Study

Background/Objectives: Rapid weight loss following sleeve gastrectomy substantially reduces mechanical loading across the lower extremities, yet its effects on patellar height remain unknown. This study investigated early postoperative radiographic changes in patellar height foll...

Artificial Intelligence and Social Trust in Earthquake Early Warning Systems: A Comparative Perspective

This study argues that earthquake early warning systems should be evaluated not only in terms of their technical efficiency but also in terms of their capacity to generate social trust. The effectiveness of these systems is shaped not only by their technical performance but also...

Perimetric Hardy--Rogers and Interpolative Contractions with a Hyers--Ulam Estimate

We study self-maps of a metric space that contract the perimeter of atriangle, in the sense of Petrov. We introduce a Hardy--Rogers typecondition that combines, in a single linear inequality, the perimeter ofthe image triangle, the displacements of the three vertices, and thecros...

A two-wave longitudinal study of geometry self-efficacy and problem-posing in pre-service mathematics teachers

Understanding how geometry self-efficacy and problem-posing self-efficacy are related over time is important for informing teacher education programs. While cross-sectional studies have examined these constructs primarily at a single time point, their longitudinal interplay remai...

On the Convergence of Slow-Fast Fractional McKean–Vlasov Stochastic Systems with Multivalued Operators

This article establishes a strong averaging principle for a class of slow-fast stochastic evolution systems that incorporate both McKean–Vlasov interactions and multivalued operators within a Hilbert-space variational framework. The slow variable υ evolves according to a Caputo f...

Optimized Wavy Thermal Radiative Analysis of Electrochemically Ternary Hybrid Nanomaterials Affected by an Induced Magnetic Force: An ANN‐Based Levenberg–Marquardt Backpropagation Approach

ABSTRACT This study is motivated by the growing demand for highly efficient thermal management fluids in modern energy systems, microelectronics and industrial heat flow processes, where conventional fluids fail to meet rising performance requirements. To address these limitation...

Uncovering the psychological mechanisms behind quarter-life crisis and suicide cognitions

Young adults may experience a quarter-life crisis due to challenges they face in education, work, and relationships. Individuals experiencing a quarter-life crisis face numerous mental health issues, including psychological distress, entrapment, hopelessness, and suicidal ideatio...

Investigation of the relationship between homophobia attitudes and gender perception among Nutrition and Dietetics, Nursing, First Aid and Emergency Care students

Homophobia remains an important social and public health concern that may contribute to stigma, discrimination, and inequalities in healthcare. Gender perceptions and socially constructed gender roles may influence individuals’ attitudes toward sexual and gender diversity, potent...

Association between minimum dietary diversity and growth among children aged 6–23 months in Pakistan: a propensity score matching approach

Minimum dietary diversity (MDD) is an important indicator of complementary feeding quality and has been associated with child nutritional status. This study examines the association between adequate MDD and growth outcomes among children aged 6–23 months in Pakistan using a poole...

A machine learning–based framework for analyzing mitral regurgitation–related signal patterns from photoplethysmography

Abstract Objectives This study investigates the feasibility of using photoplethysmography (PPG) signals for supporting mitral regurgitation (MR) assessment and monitoring using machine learning techniques. Methods MR occurs when blood flows backward from the left ventricle to the...

Ab Initio Investigation of the Tin Kagome Sublattice and Phonon-Mediated Superconductivity in SrSn3

Abstract Recent studies have shown that the intermetallic compound SrSn3 crystallizes in a layered structure in which Sn atoms form a Kagome framework. As a type-II superconductor with an experimental critical temperature of about 5.5 K, SrSn3 provides an opportunity to examine h...

Yazın Çevirisi ve Kültürel Aktarım: TR. İsimli Dergi Çevirisi Üzerine Bir İnceleme

Kültürlerarası etkileşimde çevirinin rolü, kaynak metindeki kültürel dokunun erek dildeki temsiliyet düzeyi ve aktarım başarısı ile doğrudan ilişkilidir. Bu çalışma, Yunus Emre Enstitüsü tarafından iki dilli olarak yayımlanan TR. adlı derginin 2015 Mayıs-Haziran sayısında yer ala...

Real-World Outcomes of Second-Line Chemotherapy in Metastatic Urothelial Carcinoma

Second-line chemotherapy is widely used in metastatic urothelial carcinoma after progression on first-line platinum-based therapy, but its independent contribution to survival, as opposed to selection of healthier patients, remains unclear. In this multicenter retrospective cohor...

Associations of maternal fatigue and perceived nurse–parent support with cyberchondria dimensions among mothers of hospitalized children aged 0–6 years: a path analysis

Cyberchondria has become increasingly prominent among mothers experiencing heightened uncertainty, stress, and caregiving burden during pediatric hospitalization, highlighting the critical role of professional nurse–parent support and holistic nursing care in managing this proces...

Modeling the Psychological Determinants of Student Adoption of Video-Enabled Feedback Tools

Intelligent Type-3 ANFIS-based adaptive secondary control for parallel grid-forming inverters in islanded smart microgrids

Abstract This article presents an adaptive secondary control method for islanded AC microgrids using an Enhanced Type-3 Adaptive Neuro-Fuzzy Inference System (T3-ANFIS). The considered microgrid structure consists of two parallel grid-forming (GFM) inverters operating under diffe...

Perfect $\mathcal{E}$-Error-Correcting Quantum Codes over the Hurwitz Integers

The concept of perfect $\mathcal{E}$-error-correcting codes constitutes a fundamental benchmark in classical coding theory; however, a corresponding definition for these codes remains absent in the quantum domain. This study addresses this theoretical gap by formally defining per...
