Context. Collisionally ionized plasmas produce X-ray spectra that depend on electron energy and atomic processes, requiring accurate atomic rate coefficients for modeling. [...]

This paper addresses the mode switching problem in piecewise smooth implicit multilinear initial value problems (IVPs), which are relevant for modeling hybrid dynamical systems like HVAC and power systems. Unlike traditional switched systems with explicit mode descriptions, this work focuses on systems where mode information is implicitly encoded in binary-valued variables and switching conditions are defined by inequality constraints. [...]

This article examines the influence of unintentional Cr3+and Fe3+impurity ions on the luminescent properties of Gd3Ga5O12(GGG) single crystals. The characteristic features of the spectra excited by high-energy syn-chrotron radiation in the temperature range of 10–300 K are analyzed [...]

Tau is a microtubule-associated protein that plays a critical role in regulating the organization and stability of microtubules (MTs) in neurons. Although the association of tau with MTs is well recognized, the structural consequences of its binding at steady state have remained poorly understood. [...]

Controlling the self-assembly of organic semiconductors at the nanoscale is critical for advancing high-performance electronic and photonic devices, yet remains challenging due to their intrinsic anisotropic crystallization and sensitivity to processing conditions. Here, we demonstrate that cylindrical nanoconfinement within anodic aluminum oxide membranes provides a versatile platform to precisely tune the molecular orientation and phase behavior of the prototypical organic semiconductor 2,7-dioctyl[1]benzothieno[3,2-b][1]benzothiophene (C8-BTBT-C8). [...]

We compare the fluorescence properties of CsPbBr2Cl nanocrystals, obtained via two distinct synthetic procedures, and self-assembled into supercrystals using the same antisolvent crystallization technique. By spatially resolved fluorescence (lifetime) measurements we demonstrate that the optical properties of the supercrystals depend on the specific synthesis conditions of the constituting nanocrystals. [...]

In this work, we present our recent calculation of the $W$ boson mass in the complex NMSSM, which includes all state-of-the-art higher-order supersymmetric corrections to $\Delta r$. In particular, we include the full one-loop corrections and the leading andsub-leading two-loop corrections $\mathcal{O}(\alpha + \alpha_t\alpha_s +\left(\alpha_t+\alpha_\lambda+\alpha_\kappa\right)^2)$ from the $\rho$ parameter.We show some numerical investigations of the dependence of $\Delta\rho$ on the renormalization schemes and of the dependence of $M_W$ on some selected parameters. [...]

We present novels methods aiming at recording THz waveforms in single-shot and high repetition rates, with high temporal resolution. This work is performed in the PhLAM-DESY collaboration framework, aiming at developing real-time diagnostics for THz sources, as well as monitoring the shapes of relativistic electron bunches in accelerators. [...]

The aim of this study is to explore the internal damage mechanisms of AlSi12 metal matrix syntactic foam (MMSF) with embedded ceramic hollow spheres (CHSs) to understand the damage behavior during compressive loading. To achieve this goal, in situ synchrotron X-ray tomography is used. [...]
