Heat stress and heatwave trends across Türkiye (1975–2024) using the Extended Heat Index

Heat stress is an increasingly important climate-related hazard in regions experiencing rapid warming and changing temperature–humidity interactions. This study examines heat stress and heatwave trends across Türkiye during 1975–2024 using ERA5 reanalysis data aggregated to the p...

Below the Treaty: Investment Treaties, CBAM, and Climate-Aligned Investment Law in Türkiye

Türkiye is constructing a domestic climate architecture while remaining bound by investment treaty commitments concluded decades before climate policy assumed its present form. This working paper asks which legal techniques for reconciling the two are in fact open to an economy s...

Baseline Liver Metabolic Health in Newly Diagnosed People Living with HIV Compared with HIV-Negative Controls: Cross-Sectional Findings from the Prospective MASHIV-TR Cohort

Metabolic dysfunction-associated steatotic liver disease (MASLD) is an important comorbidity in people living with HIV (PLWH), yet most data derive from individuals receiving antiretroviral therapy (ART). In the baseline cross-sectional analysis of the prospective multicentre MAS...

A Field-Calibrated Physics-Informed Digital Twin Framework for Production Blasting Using Dynamic Finite Element Modeling and Seismic Source Reconstruction

Blast-induced ground vibration is traditionally predicted using empirical scaled-distance equations or numerical simulations driven by simplified analytical loading functions. Although dynamic finite element modeling has significantly advanced the understanding of stress-wave pro...

Sustained peripheral nociceptive input disrupts interstimulus-interval-dependent sensory gating in the rat primary somatosensory cortex

Sensory gating is processed in thalamocortical pathways and depends significantly on the interstimulus interval. Somatosensory symptoms and temporal discrimination disturbances are associated with nociceptive conditions. We aimed to investigate the effects of capsaicin applicatio...

Yugoslav Geçmişin Hayaleti: Hafıza, Yugo-nostalji ve Tüketim

Yugo-nostalji Yugoslav geçmişe yönelik özlemin hafıza, aidiyet ve tüketim üzerinden yeniden anlamlandırıldığı çok katmanlı bir fenomen olarak tanımlanmaktadır. Yugoslav geçmişe ilişkin semboller, popüler kültür imgeleri ve gündelik tüketim nesneleri metalaşarak piyasa içinde dola...

Neural Gas Network-Based Distinction Between Brain Cysts and Tumors from Magnetic Resonance Images Using a Hybrid Deep Learning Algorithm

The early and accurate diagnosis of brain tumors is critically important, as timely intervention significantly reduces mortality and improves patient outcomes. While magnetic resonance imaging (MRI) is the preferred diagnostic tool, differentiating malignant brain tumors from ben...

Nursing Students' Reports of Patient Safety Incidents and Reasons During Clinical Placements: A Secondary Analysis of the International Data

ABSTRACT Clinical placements expose nursing students to patient safety incidents and provide important opportunities for learning about safe care. This study explored how nursing students in four countries recognized and interpreted patient safety incidents encountered or witness...

Diagnostic Delay in Gaucher Disease and the Role of Gastroenterology in the Diagnostic Journey: A Real-World Cohort Study

Background/Objectives: Gaucher disease (GD) is a rare lysosomal storage disorder with heterogeneous and often nonspecific clinical manifestations. Despite increasing awareness of Gaucher disease (GD), diagnostic delay remains a clinical challenge because of its heterogeneous and...

The Effect of Bioactive Liner Materials on the Bond Strength of Universal Adhesives to Dentin

Objective: This in vitro study aims to investigate how different bioactive base materials influence the bond strength of two universal adhesive systems, Single Bond Universal and Prime&Bond Universal, when applied to dentin-liner complexes. Understanding the interaction between a...

Investigating the roles of experiential avoidance, emotion regulation difficulties and preoccupation with figure and weight in the relationship between post-traumatic stress and disordered eating in a sample of trauma-exposed women

Abstract Background This study aimed to test a cross-sectional model investigating the indirect association of experiential avoidance, emotion regulation difficulties, and preoccupation with figure and weight in the relationship between posttraumatic stress symptoms (PTSS) and di...

Lateral Cyclic Performance of Initially Cracked Steel SHS Columns Strengthened with CFRP Wrapping Under Different Axial Load Ratios

Steel square hollow section (SHS) members are widely used in buildings, bridges, and industrial structures due to their high strength-to-weight ratio and torsional resistance. In steel SHS members, crack-like initial defects may occur due to environmental effects, especially corr...

Development and Validation of an International Classification of Functioning, Disability and Health–Based Communication Screening Scale for Preschool Children

PURPOSE: This study aimed to develop and validate the International Classification of Functioning, Disability and Health (ICF)-based Communication Screening Scale (CSS) for monolingual Turkish-speaking preschool children, grounded in the ICF framework and based on parent report....

Beyond optimisation: Revisiting energy demand management

Energy demand reduction (EDR) in households has re-emerged as a central pillar of climate and energy transition strategies in Europe and beyond. While energy efficiency has long dominated policy frameworks, growing evidence shows that efficiency alone is insufficient to achieve a...

Review of 3D-Printed Cementitious and Geopolymer Permanent Formwork for Concrete Structures

Three-dimensional concrete printing (3DCP) has emerged as a promising technology for developing stay-in-place cementitious and geopolymer permanent formwork systems. This review critically synthesizes current knowledge on printable materials, printability requirements, structural...

Temperature–Load‐Dependent Wear Transitions of PH 15–5 Stainless Steel Under Dry Sliding

The dry sliding behavior of PH 15–5 precipitation‐hardened stainless steel was investigated at room temperature and −40 °C under 10 and 20 N using reciprocating ball‐on‐disc tests. A 6 mm WC–Co ball was used at 34 mm s −1 for 30 min, corresponding to 61.2 m sliding distance. Fric...
