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

Social-sparsity brain decoders: faster spatial sparsity [PDF]

open access: yes, 2016
Spatially-sparse predictors are good models for brain decoding: they give accurate predictions and their weight maps are interpretable as they focus on a small number of regions.

A Theory of X and Z Multiquark Resonances [PDF]

open access: yes, 2017
We introduce the hypothesis that diquarks and antidiquarks in tetraquarks are separated by a potential barrier. We show that this notion can answer satisfactorily long standing questions challenging the diquark-antidiquark model of exotic resonances. The

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 ...
