Hyperspectral Image Super-Resolution Using a Hybrid Method Combining Deep Learning and Sparse Representation

Background/Aim: Hyperspectral images provide rich spectral information but often suffer from low spatial resolution due to hardware limitations and long imaging distances. This study aims to enhance the spatial resolution of low-resolution hyperspectral images while preserving th...

Bond characteristics of GFRP and BFRP bars embedded in Self-Compacting Concrete with different substitutes

This study investigates the bond behavior of GFRP, BFRP, and steel bars in Self-Compacting Concrete (SCC) with and without cement replacements. Three specific SCC mixtures were developed: a control batch using only Portland Cement (PC), one utilizing Fly Ash (FA) as a partial PC...

Intervention with a handmade closed-loop balloon stent for a pulmonary artery fistula not closed by coil

Abstract Background: Coronary–pulmonary artery fistulas (CPAF) are rare anomalies that may cause coronary steal and clinical symptoms. Coil embolisation is often effective, but residual flow can persist in large fistulas. Case: A 70-year-old male with coronary artery disease unde...

Synthesis and Characterization of Polyaniline Using Potassium 3-(Trifluoromethyl)phenyltrifluoroborate and Ni(II) Ions: Photocatalytic Degradation of Methylene Blue under UV Light

In this study, three polyaniline (PANI) samples were synthesized under different experimental conditions to investigate the effects of potassium 3-(trifluoromethyl)phenyltrifluoroborate (PTMPB) and Ni(II) ions on their physicochemical and photocatalytic properties. To the best of...

Preoperative Aspartate Aminotransferase-to-Platelet Ratio Index and Postpartum Haemorrhage after Caesarean Delivery

Purpose: Postpartum haemorrhage (PPH) is a leading cause of maternal death, yet a simple preoperative marker of risk is lacking. The aspartate aminotransferase-to platelet ratio index (APRI) has been linked to adverse outcomes in non-hepatic surgery and in pregnancy complications...

Residual sequential attention and class-imbalance learning for multi-class peripheral blood cell classification

Abstract Peripheral blood cell classification is challenging when severe class imbalance coincides with fine visual differences among maturation stages and morphologically related cell types. This study investigates a residual sequential attention framework built on ResNeSt50 and...

Exploring exercise behavior, physical activity level, and perceived barriers in women with lipedema: a case-control study

Lipedema is a chronic adipose tissue disorder characterized by pain and disproportionate fat distribution. Although exercise is an important component of lipedema management, evidence regarding exercise behavior, physical activity, and related barriers remains limited. This study...

Quality and Educational Content of Biomimetic Dentistry Videos on YouTube and TikTok: A Cross-Sectional Study

Purpose: The increasing use of social media as a source of health information has raised concerns regarding the quality and reliability of online educational content. This study aimed to evaluate and compare the quality, reliability, and educational content of biomimetic dentistr...

Protective Effects of Esculetin at two Different Doses on Oxidative Stress, Inflammation, and Fibrotic Changes in AlCl₃-Induced Cardiotoxicity in Rats

Objective: Aluminum chloride (AlCl₃) is an environmental toxicant that promotes cardiotoxicity primarily by inducing oxidative stress and inflammatory responses. Esculetin (ESC), which is a naturally occurring coumarin derivative, possesses antioxidant, anti-inflammatory, and ant...

Atomization and Characterization of Tungsten Heavy Alloy Powders

This paper investigates the Electrode Induction Gas Atomization (EIGA) of a Class 4 tungsten heavy alloy (WHA-4) containing 97.8 wt.% W, with the balance comprising Ni and Fe. Compared with conventional tungsten heavy alloys containing less than 95 wt.% W, the high tungsten conte...

Classification of Seasonal Allergic Rhinitis Patients by Prospective Patient‐Recorded Symptoms: The @ IT .2020 Project

BACKGROUND: Seasonal allergic rhinitis (SAR) has been so far classified according to frequency and severity by retrospective information based on the ARIA (Allergic Rhinitis and its Impact on Asthma) classification. Electronic symptom diaries (e-Diaries) are feasible tools to col...

Investigation of Surface Roughness, Tool Wear, and Chip Form in Lathe Machining of High Manganese Austenitic Steel

This study aimed to investigate surface roughness, tool wear, and chip formation in the machining of high-manganese austenitic steel. For this purpose, machining experiments were conducted using the turning method with three different cutting speeds, two different feed rates, and...

An application for citizen participation: the open-door units of Ministry of Interior

Participation, as one of today’s key concept, not only ensures citizens' involvement in the administrative process but also plays a crucial role in the feasibility of democracy alongside transparency and accountability. The concept of participation, which did not find much place...

The paradox of compassion: The mediating role of psychological well-being in the association between compassion for others and resilience among emerging adults
