Der Nicht‐Adiabatische Charakter von Substituenteneffekten in Azobenzol
Angewandte Chemie, EarlyView.Vereinheitlichung Nicht‐Adiabatischen Schaltens: die thermische Z→E Isomerisierung von para‐substitutierten Azobenzolen verläuft über einen einzelnen Reaktionsweg mit nicht‐adiabatischem Charakter. Anstatt eines mechanistischen Wechsels spiegelt der bekannte V‐förmige Hammett Graph ein Artefakt des σp Parameters, zeigt so die Grenzen von DFT auf und ...

Kontrolle heterogener Katalyse mittels Unter‐Oberflächen‐Sauerstoff
Angewandte Chemie, EarlyView.Während der CO‐Oxidation auf Rhodiumoberflächen wird die Reaktionsdynamik in der Gegenwart von Unter‐Oberflächen‐Sauerstoff (Osub) deutlich verändert. Unter‐Oberflächen‐Sauerstoff stabilisiert vorübergehend durch Oberflächenreaktionen gebildetes physisorbiertes CO2, was diesem ermöglicht, vorübergehend zu binden und mit der Oberfläche zu thermalisieren.

Kaon electromagnetic form factors in dispersion theory
European Physical Journal C: Particles and Fields, 2022 The electromagnetic form factors of charged and neutral kaons are strongly constrained by their low-energy singularities, in the isovector part from two-pion intermediate states and in the isoscalar contribution in terms of $$\omega $$ ω and $$\phi $$ ϕ ...

Rank‐based estimation of propensity score weights via subclassification
Canadian Journal of Statistics, EarlyView.Abstract Propensity score (PS) weighting estimators are widely used for causal effect estimation and enjoy desirable theoretical properties, such as consistency and potential efficiency under correct model specification. However, their performance can degrade in practice due to sensitivity to PS model misspecification.

Asymptotic independence in more than two dimensions and its implications on risk management
Canadian Journal of Statistics, EarlyView.Abstract In extreme value theory, the presence of asymptotic independence signifies that joint extreme events across multiple variables are unlikely. Although well understood in a bivariate context, the concept remains relatively unexplored when addressing the nuances of simultaneous occurrence of extremes in higher dimensions.

International Dialogues on Education: Past and Present, 2017 The following text explores existing arguments for a new view on the tasks of the education system from a tradition of Christian thought. It takes up what can be considered the sense and promise of baptism in its argument for the endorsement of the ...

A Markov approach to credit rating migration conditional on economic states
Canadian Journal of Statistics, EarlyView.Abstract We develop a model for credit rating migration that accounts for the impact of economic state fluctuations on default probabilities. The joint process for the economic state and the rating is modelled as a time‐homogeneous Markov chain. While the rating process itself possesses the Markov property only under restrictive conditions, methods ...

Dynamical onset of light-induced unconventional superconductivity—a Yukawa-Sachdev-Ye-Kitaev study
Communications PhysicsUsing light irradiation to manipulate quantum materials has opened up avenues for transiently inducing superconductivity in some systems. Despite experimental confirmation across various compounds, the mechanism behind the dynamic formation of Cooper ...

Correlations in multithermostat Brownian systems with Lorentz force
New Journal of Physics, 2020 We study the motion of a Brownian particle subjected to Lorentz force due to an external magnetic field. Each spatial degree of freedom of the particle is coupled to a different thermostat.
