Composite boson dominance in many-fermion systems

open access: yes, 2007
I recently proposed a method of bosonization based on the use of coherent states of fermion composites, whose validity was restricted to smooth structure functions. In the present paper I remove this limitation and derive results which hold for arbitrary

Von Sauerstoff zu Tellur: Der Einfluss des Chalkogenatoms auf die Nucleophilie und Basizität von Isochalkogenharnstoff‐basierten Katalysatoren

open access: yesAngewandte Chemie, Volume 137, Issue 48, November 24, 2025.
Der Einbau verschiedener Chalkogenatome (O, S, Se oder Te) in häufig verwendete Isochalkogenharnstoff‐Organokatalysatoren ermöglicht die Feinabstimmung ihrer Nucleophilie und Basizität. Kinetische und thermodynamische Deskriptoren für die molekularen Eigenschaften der Katalysatoren werden als Werkzeuge zur Vorhersage ihrer Effizienz eingeführt und in ...

Continuation of Nesterov's Smoothing for Regression with Structured Sparsity in High-Dimensional Neuroimaging

open access: yes, 2018
Predictive models can be used on high-dimensional brain images for diagnosis of a clinical condition. Spatial regularization through structured sparsity offers new perspectives in this context and reduces the risk of overfitting the model while providing

Pleistocene Climate Changes and Lineage Diversification of Sphenarium Grasshoppers (Orthoptera: Pyrgomorphidae)

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
We investigate the phylogeographic history and paleodistribution patterns of four closely related grasshopper species of the genus Sphenarium to test the relative impact of Pleistocene climate fluctuations on their diversification. We found that each species responded differently to these fluctuations, but their divergence, distribution, and ...
