33rd GP2A Annual Medicinal Chemistry Conference, XIVth Paul Ehrlich MedChem Euro-PhD Network Meeting & COST Action One Health Drugs Against Parasitic Vector Borne Diseases in Europe and Beyond (OneHealthdrugs)

The 33rd Annual Conference of the Group for the Promotion of Pharmaceutical Chemistry in Academia (GP2A), held in Nantes from 11 to 13 June 2025, marked a significant expansion of the organization’s scope and collaborative efforts. Building on the success of the previous meeting...

Lightweight Llama Models with Experts’ Curated RAG for Electrical Engineering Education: An Exploratory Comparison

This study investigates the benefits of expanding small and open Large Language Models (Llama 3.x family) with retrieval and explicit referencing (retrieval-augmented generation), configured to refuse to respond when unsure about the answer. Additionally, we compare this augmente...

High-PerformingVacuum-Pressure Swing Adsorption Unitfor Drying Hydrogen from Water Electrolysis

Abstract The growing demand for ultrapure hydrogen in fuel cell applications requires the development of efficient and cost-effective purification technologies. This study reports the development, optimization, and techno-economic assessment of a vacuum-pressure swing adsorption...

Where the Self Places Conflict: Reality Resistance, Organism–Environment Coupling, and Conditional Return

This paper introduces a VIVENS state-space-inspired research framework for studying conflict as a bidirectionally coupled organism–environment process. The framework distinguishes reality resistance—the mismatch between an expected, desired, defended, or identity-compatible organ...

Characterization and treatment of polymicrobial biofilms in prosthetic joint infections

Abstract Prosthetic joint infections are complex and associated with high economic and social costs. Polymicrobial cases remain poorly understood, particularly regarding bacterial interactions and antibiotic response within mixed-species biofilms. We introduce two approaches for...

Cross-Cultural Validation and Psychometric Evaluation of the Birth Beliefs Scale Among Portuguese Pregnant Women

BACKGROUND: Beliefs about childbirth shape women's expectations, decisions, and experiences. Although several tools assess related constructs such as fear or self-efficacy, few instruments focus specifically on childbirth beliefs. The Birth Beliefs Scale (BBS) addresses this gap...

Data-driven identification of modifiable risk factors for colorectal cancer in Palestine using machine learning methods

Colorectal cancer (CRC) is a growing public health concern in Palestine, yet limited evidence is available on locally relevant behavioral, dietary, socioeconomic, and contextual predictors. Machine learning (ML) may support prevention-oriented risk stratification by identifying c...

Catalytic Ozonation of Environmentally Relevant Pharmaceuticals Using Oxygen- and Nitrogen-Doped Activated Carbons

Catalytic ozonation is one of the advanced oxidation processes (AOPs) that have yielded promising results in the treatment of emerging pollutants, in which the catalyst plays a fundamental role. In this study, surface oxygen and nitrogen groups were introduced onto two commercial...

Conformal principal-asymptotic nets: Parametric design and modular construction of elastic gridshells

Current modular design approaches often rely on numerical optimization to satisfy fabrication constraints, which can be computationally intensive and sensitive to initial geometric conditions. This work introduces a parametric design algorithm based on Conformal Principal-Asympto...

Telephone versus in-person administration of the Early Childhood Development Index 2030: a crossover study, Brazil, Canada, India and Malawi.

Objective: To examine agreement between telephone and in-person administration of the Early Childhood Development Index 2030 (ECDI2030) survey. Methods: -tests and intraclass correlation coefficients. Findings: : -0.36), regardless of modality. However, pooled and stratified intr...
