An Integrated Workflow for Enriched 3D (e3D) Models to Support Conservation Practices in Cultural Heritage: The ChemiNova Project

The project ChemiNova, funded by the Horizon Europe program, is dedicated to the development of an integrated suite of five software modules to enhance the conservation, analysis, and monitoring of cultural heritage assets. Using non-invasive data acquisition technologies, we pro...

Structure–Property Relationships in Bioactive Poly (Vinyl Alcohol) Films Incorporating Natural Phenolic Additives for Sustainable Active Packaging

This study aimed to investigate bioactive poly (vinyl alcohol) (PVA) films incorporating three chemically distinct naturally phenolic additives—aronia extract (A), apple peel extract (AP), and rutin (R)—as individual functional modifiers for active packaging applications. Here, w...

Synergistic friction and wear reduction in CuSn10-modified basalt fiber-reinforced epoxy composites via protic ionic liquid and graphene nanolubrication

Basalt fiber-reinforced epoxy (BFRP) composites combine a favorable strength-to-weight ratio with relatively low cost, which makes them attractive for structural applications. However, the epoxy matrix has limited abrasion resistance, and this restricts how well these composites...

An Integral Formula for the Inhomogeneous Jordan–von Neumann Equation

Abstract We study the inhomogeneous form of the Jordan–von Neumann quadratic functional equation, in which the right-hand side is a prescribed function of two real variables. We prove that a twice continuously differentiable solution exists if and only if the prescribed data has...

Synthetic-Fiber Strip Reinforcement of Glulam Beams: Bond, Recovery, and Flexural Response

This study reanalyzes an archived experimental program on textured polyethylene terephthalate (PET) and polyester-fiber strips used as internal tensile reinforcement in glued-laminated timber (glulam) beams. The pull-out stage comprised one specimen (n = 1) per reinforcement-morp...

From Empirical Prime-Phase Dynamics to a PNT Phase Theorem

Derives a one-parameter logarithmic phase law for weighted prime trajectories directly from the Prime Number Theorem. The framework explains radial growth, angular velocity, and the phase anchor analytically, with numerical validation up to 10^9.

Study on the Youth Attitude Towards Food Waste in the North-West Region of Romania

This study aims to evaluate young people’s perceptions, attitudes, and behaviors regarding food waste in the North-West region of Romania. It seeks to identify key factors influencing awareness and practices, quantify the attitude–behavior gap, and propose targeted educational an...

Development of a Virtual Laboratory Stand Using Simscape for Mechatronic Engineering Education

Laboratories play a critical role in engineering education by bridging the gap between theoretical knowledge and practical applications. Dedicated laboratory stands serve as essential platforms for experiential learning, enabling students to interact directly with real or simulat...

Human centered artificial intelligence for smart city traffic coordination

Abstract Smart city traffic systems increasingly rely on edge intelligence and distributed learning to coordinate vehicles and infrastructure. However, many existing approaches prioritize system-level optimization while overlooking how humans perceive, interpret, and respond to a...

Reimagining digital literacy and virtual identity in the Age of AI” - Special Collection Editorial

This special collection reflects on the need to reimagine teaching and learning spaces in the age of artificial intelligence (AI). Understanding digital literacy and virtual identity is essential to engaging with our contemporary society, which is defined by the fast pace of soci...
