White Matter Microstructure Alterations in Older Adults With Dyslipidemia Associated With Cognitive and Locomotor Dysfunction Evaluated Using Neurite Orientation Dispersion and Density Imaging

open access: yesBrain and Behavior, Volume 15, Issue 6, June 2025.
This study used NODDI to identify white matter microstructure alterations in older adults with dyslipidemia, revealing significantly reduced neurite density in several brain regions. These reductions were linked to declines in cognitive and motor functions, suggesting that NODDI may serve as a biomarker for dyslipidemia‐related axonal degeneration ...

Spatial and seasonal trait selection in dung beetle assemblages along an aridity gradient in the Sahara

open access: yesEcology, Volume 106, Issue 5, May 2025.
Abstract Ecological communities under extreme environments are shaped by a balance of environmental filtering and coexistence mechanisms that result in a series of assembly rules. Although there is abundant evidence about the importance of these community assembly mechanisms in plants, their effects have been seldom compared for animals.

Cohesive particle–fluid systems: An overview of their CFD simulation

open access: yesThe Canadian Journal of Chemical Engineering, Volume 103, Issue 4, Page 1582-1601, April 2025.
Abstract Solid particles may experience different kinds of cohesive forces, which cause them to form agglomerates and affect their flow in multiphase systems. When such systems are simulated through computational fluid dynamics (CFD) programs, appropriate modelling tools must be included to reproduce this feature.

The Role of the Dorsolateral Prefrontal Cortex in Ego Dissolution and Emotional Arousal During the Psychedelic State

open access: yesHuman Brain Mapping, Volume 46, Issue 5, 01 April 2025.
We analyzed and integrated data from two separate types of brain scans, fMRI and MEG, from 15 healthy human participants on the psychedelic drug LSD. Our work identified changes in the connectivity of a frontal brain region, which relate to two common experiences on LSD: emotional arousal and ego dissolution.

On Nichols algebras of diagonal type [PDF]

open access: yesJournal für die reine und angewandte Mathematik (Crelles Journal), 2013
We give an explicit and essentially minimal list of defining relations of a Nichols algebra of diagonal type with finite root system. This list contains the well-known quantum Serre relations but also many new variations. A conjecture by Andruskiewitsch and Schneider states that any finite-dimensional pointed Hopf algebra over an algebraically closed ...

On Hopf algebras over the unique $12$-dimensional Hopf algebra without the dual Chevalley property

open access: yes, 2018
Let $\mathds{k}$ be an algebraically closed field of characteristic zero. We determine all finite-dimensional Hopf algebras over $\mathds{k}$ whose Hopf coradical is isomorphic to the unique $12$-dimensional Hopf algebra $\mathcal{C}$ without the dual ...

Basis of Nichols Braided Lie Algebras

open access: yes, 2017
Assume that $V$ is a braided vector space with diagonal type. It is shown that a monomial belongs to Nichols braided Lie algebra $\mathfrak L(V)$ if and only if this monomial is connected. A basis of Nichols braided Lie algebra and dimension of Nichols braided Lie algebra of finite Cartan type are obtained.
