Lectrical stabilization of CdZnTe by argon plasma treatment and diamond-like carbon passivation

The high specific resistance of CdZnTe-based radiation detectors enables high energy resolution and detection sensitivity, as it determines the device's leakage currents. In this work, an ion-plasma surface treatment was developed to enhance the electrical stability and radiation...

Multidimensional parabolic equations with a logarithmic nonlinearity admitting exceptional Lie symmetries

Abstract Nonlinear reaction-diffusion equations arise in a very wide range of applications. Here we address a specific multidimensional class in which the source term is non-autonomous in time, this choice being motivated both by its relevance to a broad class of (autonomous) ‘ne...

Trust in the conduct of health and implementation research in conflict-induced humanitarian settings: a narrative literature review and preliminary theoretical framework

Conducting research in settings marked by violence is essential for generating credible knowledge to improve humanitarian responses. While its importance is widely acknowledged, the practice of health research, and implementation research in particular, is rarely itself a focus o...

Velar palatalisation in Common Slavic: evidence from the Kryvorivnja dialect of Ukrainian

Abstract This article revisits a mechanism of the first two primary palatalisations of velar stops before unrounded front vowels and in the clusters *ki̯ and *gi̯ in Common Slavic. I ground the discussion in the analysis of the new acoustic data from Kryvorivnja (Southeast Hutsul...
