In this paper, a comprehensive energy management framework for microgrids that incorporates price-based demand response programs (DRPs) and leverages an advanced optimization method-Greedy Rat Swarm Optimizer (GRSO) is proposed. The primary objective is to minimize the generation cost and environmental impact of microgrid systems by effectively scheduling distributed energy resources (DERs), including renewable energy sources (RES) such as solar and wind, alongside fossil-fuel-based generators. Four distinct demand response models-exponential, hyperbolic, logarithmic, and critical peak pricing (CPP)-are developed, each reflecting a different price elasticity of demand.

Power quality (PQ) disturbances, such as voltage sags, are significant issues that can lead to damage in electrical equipment and system downtime. Detecting and classifying these disturbances accurately is essential for maintaining reliable power systems. This paper introduces a novel approach to voltage sag analysis by employing wavelet packet analysis combined with energy-based feature extraction to enhance PQ monitoring.

In order to make the transition from a linear to a circular economy, unprecedented measures are required from all social actors. Communication plays a fundamental role in this transition. The use of social marketing as an alternative to traditional communication models can promote the paradigm shift in order to increase communicative effectiveness.

Background: Bronchiolitis Obliterans Syndrome (BOS), a fibrotic airway disease that may develop after lung transplantation, conventionally relies on pulmonary function tests (PFTs) for diagnosis due to limitations of CT imaging. Deep neural networks (DNNs) have not previously been used for BOS detection. This study aims to train a DNN to detect BOS in CT scans using an approach tailored for low-data scenarios.

Introduction: Pulmonary arterial hypertension (PAH) is a complex condition affecting quality of life, characterised by high blood pressure in the pulmonary arteries leading to heart strain. PAH's impact extends beyond physical symptoms, influencing emotional and social well-being, particularly in women where it affects sexual health and pregnancy outcomes. Despite medical advancements, the disease's full impact on women's lives is under-researched, especially regarding sexual experiences and health.
