Frequency‐Domain Subspace Identification for Noninvasive Transformer Winding Parameter Estimation and Fault Diagnostics

open access: yesInternational Journal of Circuit Theory and Applications, EarlyView.
Noninvasive frequency‐domain method estimates transformer winding parameters from terminal measurements, eliminating the need for design data. ABSTRACT A novel frequency‐domain subspace identification method enables precise estimation of transformer winding ladder network parameters directly from terminal measurements.

Ionization Potential Depression and Fermi Barrier in Warm Dense Matter: A First‐Principles Approach

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Ionization potential depression (IPD) is of crucial importance to understand and accurately predict the properties of dense, partially ionized plasmas. Many models of IPD have been developed that, however, exhibit largely varying results. Recently, a novel approach was proposed that is based on first‐principles quantum Monte Carlo simulations ...

Instantaneous Normal Modes of Yukawa Liquids

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT The instantaneous normal mode (INM) approach, which extends the normal mode description of collective excitations in solids to liquids, is applied to strongly coupled, three‐dimensional Yukawa liquids. Based on data from Langevin dynamics simulations, we compute the instantaneous normal modes across a wide range of coupling and screening ...

Non‐Markovian Quantum Kinetic Simulations of Uniform Dense Plasmas: Mitigating the Aliasing Problem

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Dense quantum plasmas out of equilibrium are successfully modeled using quantum kinetic equations, such as the quantum Boltzmann, Landau, or Balescu–Lenard equation. However, these equations do not properly take into account correlation effects, which require the use of generalized non‐Markovian kinetic equations.

Rational Control of C–N Axial Chirality in Bis‐Pentatomic N‐Pyrazolyl Maleimides through an Experimental and Computational Approach

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The configurational stability of a series of axially chiral bis‐pentatomic compounds of the N‐pyrazolyl maleimide scaffold has been investigated through a combined theoretical and experimental approach. The experimental values of the barriers to enantiomerisation of the title compounds are determined through dynamic high performance liquid ...

Cognitive Mechanism of Influence of Subjective Social Class on Prosocial Risky Behaviour

open access: yesEuropean Journal of Social Psychology, EarlyView.
ABSTRACT Prosocial risky behaviour (PRB) combines risk and prosociality, defined as risk‐taking for the benefit of others or society. Its differences across subjective social classes and underlying mechanisms are unclear. Study 1 (n = 590) used a questionnaire to explore the relationship between subjective social class and PRB.
