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.

CP, T and fundamental interactions [PDF]
, 2012 We discuss the importance of the CP (simultaneous particle-antiparticle and left-right permutation) and T (time reversal) symmetries in the context of fundamental interactions.

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.

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 ...

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 ...

Don't You Know That You're Toxic? How Influencer‐Driven Misinformation Fuels Online Toxicity
Psychology &Marketing, EarlyView.ABSTRACT Research on misinformation has focused on message content and cognitive bias, overlooking how source type shapes toxic engagement. This study addresses that gap by showing that influencer‐driven misinformation does not merely increase toxicity: it reconfigures its nature and persistence through relational and social influence mechanisms ...

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 ...

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.

Hinweise zu einer Theorie der Medienpädagogik [PDF]
, 2008 Wenn medienpädagogische Theorien Medien diskutieren und zugleich Medien verwendet werden, um die Theorie mitzuteilen, dann fällt die Theorie in ihren Gegenstandsbereich und ist von ihrem Gegenstand betroffen. Eine von Medien unabhängige Theorie ist dabei
