Combined Molecular Dynamics and Micromagnetic Modeling of Nanocomposite Permanent Magnet Particle Arrangement and Properties

Nanocomposite rare-earth permanent magnets composed of exchange-coupled hard magnetic nanoparticles offer a promising route toward high-performance, rare-earth-efficient magnet technologies. In this work, we investigate the structural self-organization and magnetic hysteresis beh...

Multimodal Correlates of Longitudinal Functional Decline in Behavioral Variant Frontotemporal Dementia (bvFTD)

Background and Objectives: Functional decline is a major determinant of disability, caregiver burden, and loss of independence in behavioral variant frontotemporal dementia (bvFTD). Although bvFTD is characterized by early and rapidly progressive deterioration in everyday functio...

Toroidal quasi-dark supermodes in microwave dielectric metasurfaces

We report a class of dielectric metasurfaces that support quasi-dark microwave resonances with tailored toroidal and antitoroidal field profiles. The metasurfaces are realized using quadrumers of high-permittivity and low-loss ceramic disk resonators as elementary building blocks...

Journalism: Innate Talent or Academic Discipline? Reassessing Professional Identity in Greece

The ontological status of journalism in Greece has long been marked by a profound tension between the perception of the field as an innate craft and its institutionalization as an academic discipline. This paper investigates the perceived utility of university-level journalism ed...
