Property $(T)$ for locally compact groups and $C^*$-algebras

open access: yesProceedings of the American Mathematical Society, 2019
Let $G$ be a locally compact group and let $C^*(G)$ and $C^*_r(G)$ be the full group $C^*$-algebra and the reduced group $C^*$-algebra of $G$. We investigate the relationship between Property $(T)$ for $G$ and Property $(T)$ as well as its strong version for $C^*(G)$ and $C^*_r(G)$.

Increased segregation of brain networks in focal epilepsy: An fMRI graph theory finding

open access: yesNeuroImage: Clinical, 2015
Focal epilepsy is conceived of as activating local areas of the brain as well as engaging regional brain networks. Graph theory represents a powerful quantitative framework for investigation of brain networks.

Carex pulicaris abundance is positively associated with soil acidity, rainfall and floristic diversity in the eastern distribution range

open access: yesScientific Reports, 2022
Carex pulicaris is considered an endangered species, and further losses are forecast under the influence of even moderate climate change. Local studies indicate that temporal declines in C.

Liftings and the property of Baire in locally compact groups [PDF]

open access: yesProceedings of the American Mathematical Society, 1993
R. A. Johnson showed the non-existence of translation-invariant Borel liftings for the Haar measure on \(\mathbb{R}/\mathbb{Z}\). This result has been extended to non-discrete locally compact Abelian groups by M. Talagrand and also in paper of J. Kupka and P. Prikry.

Chemical diversity in a metal–organic framework revealed by fluorescence lifetime imaging

open access: yesNature Communications, 2018
Metal-organic frameworks are typically characterized by a variety of techniques, but most only provide information on properties as an average of a bulk sample.

Temporal-topological properties of higher-order evolving networks

open access: yesScientific Reports, 2023
Human social interactions are typically recorded as time-specific dyadic interactions, and represented as evolving (temporal) networks, where links are activated/deactivated over time.

Unveiling the photophysical properties of Boron-dipyrromethene dyes using a new accurate excited state coupled cluster method.

open access: yesJournal of Chemical Theory and Computation, 2019
Boron-dipyrromethene (BODIPY) molecules form a class of fluorescent dyes known for their exceptional photoluminescence properties. Today, they are used extensively in various applications from fluorescent imaging to opto-electronics. The ease of altering

Interactions between auditory statistics processing and visual experience emerge only in late development

open access: yesiScience, 2021
Summary: The auditory system relies on local and global representations to discriminate sounds. This study investigated whether vision influences the development and functioning of these fundamental sound computations.

On the Dynamical Behavior of Cellular Automata on Finite Groups

open access: yesIEEE Access
During the last few decades, significant efforts have been devoted to analyze the dynamical behavior of cellular automata (CAs) on cyclic groups, their Cartesian power (referred to as linear cellular automata), and on general abelian groups (referred to ...
