Determination of Efficacy of Intervention based on the Cognitive-Behavioral Therapy Model of Panic Attack Treatment in Comorbid Heart Diseases: A Pilot Randomized Controlled Trial

Background: Panic disorder (PD) and cardiovascular disease (CVD) exhibit similar symptoms, such as palpitations, dyspnea, and chest pain, complicating clinical differentiation, especially when they coexist. This overlap has led to challenges in the context of psychocardiology, in...

Interpretable modeling for material transportation process in an industrial cement vertical roller mill

Abstract Vertical roller mills (VRMs) dominate cement finish grinding because of their high efficiency and dry operation. However, the interaction among ventilation, fan operation, and pneumatic material transport remains poorly quantified using plant data. In this study, the pre...

Typology of transit-oriented development to promote sustainable urban structure

<title>Abstract</title> Transit-Oriented Development (TOD) has emerged as a transformative strategy in sustainable urban planning, aiming to integrate land use and public transportation to foster compact, walkable, and mixed-use communities centered around high-capacity transit s...

Exploring the impact of human development, education and R&D expenditures on nation brand competitiveness: evidence from cross-country panel data

Purpose This study investigates the impact of education and research and development (R&amp;D) expenditures on nation brand value (NBV), while also considering the roles of government effectiveness (GE) and human development. This study aims to provide insights into how investmen...

Branding as Market-Facing Infrastructure: A Research-through-Design Study of Lalejin Pottery

Lalejin, in Iran's Hamedan Province, is a historically significant pottery-producing centre in which substantial craft skill and recognised ceramic heritage coexist with fragmented market presentation, limited maker attribution and weak mechanisms for connecting products to maker...

Enhanced oxidative bioleaching of Cd-bearing ZnS concentrate in moderately thermophilic conditioning, comparing additives effects at high pulp density

The study aimed to enhance the dissolution rates of zinc (Zn) and cadmium (Cd) in sphalerite concentrates through bioleaching using moderately thermophilic bacteria. The research explored the impact of various additives, such as silver ions (Ag + ), L -cysteine, pyrite, elemental...

Modulatory effects of branched-chain amino acid supplementation on neuroendocrine disturbances following traumatic brain injury in rats

Traumatic brain injury (TBI) is frequently accompanied by neuroendocrine disturbances involving the hypothalamic–pituitary–thyroid (HPT) axis and vitamin D–calcium–phosphorus homeostasis. Despite increasing interest in nutritional strategies after TBI, the effects of branched-cha...

High-accuracy UAV photogrammetry and GIS integration for 3D cadastral data generation

Abstract This study presents a UAV photogrammetry and GIS-based workflow for generating high-accuracy three-dimensional cadastral models in urban environments. The proposed framework integrates RTK-enabled UAV image acquisition, ground control point (GCP) surveying, photogrammetr...

An integrated graph neural network and structure-based workflow for the discovery of allosteric PCSK9 inhibitors

Proprotein convertase subtilisin/kexin type 9 (PCSK9) plays a central role in cholesterol homeostasis by promoting the degradation of low-density lipoprotein receptors (LDLR), making it an attractive therapeutic target for cardiovascular disease. Although monoclonal antibodies an...

Frontal spectral entropy as a candidate individual-difference correlate of within-session accuracy change in youth soccer: an exploratory fixed-order study

Choking under evaluative pressure is often described in sport, yet its within-session neural and behavioural correlates in youth athletes remain poorly characterised. In this exploratory, fixed-order study we asked whether changes in soccer decision accuracy over the course of a...
