The topological Bloch-Floquet transform and some applications

open access: yes, 2012
We investigate the relation between the symmetries of a Schr\"odinger operator and the related topological quantum numbers. We show that, under suitable assumptions on the symmetry algebra, a generalization of the Bloch-Floquet transform induces a direct

A Recursive Model Approach to Include Epigenetic Effects in Genetic Evaluations Using Simulated DNA Methylation Effects

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The advancement of epigenetics has highlighted DNA methylation as an intermediate‐omic influencing gene regulation and phenotypic expression. With emerging technologies enabling the large‐scale and affordable capture of methylation data, there is growing interest in integrating this information into genetic evaluation models for animal ...

Dynamical Behavior Analysis of Generalized Chen–Lee–Liu Equation via the Riemann–Hilbert Approach

open access: yesFractal and Fractional
In this paper, we investigate the dynamics of the generalized Chen–Lee–Liu (gCLL) equation utilizing the Riemann–Hilbert method to derive its N-soliton solution.

Atrial Fibrillation Treatment Stratification Based on Artificial Intelligence‐Driven Analysis of the Electrophysiological Complexity

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Atrial Fibrillation (AF) treatment strategies are suboptimal and clinical predictors of success are limited. Artificial Intelligence (AI) has arisen as a powerful tool for treatment efficacy prediction. Objective We developed an AI‐driven platform for the stratification of patients based on noninvasive Electrocardiographic Imaging ...

Neurodevelopmental and psychiatric conditions in 600 Swedish children with the avoidant/restrictive food intake disorder phenotype

open access: yesJournal of Child Psychology and Psychiatry, EarlyView.
Background Avoidant restrictive food intake disorder (ARFID) is a feeding and eating disorder characterized by extremely restricted dietary variety and/or quantity resulting in serious consequences for physical health and psychosocial functioning. ARFID often co‐occurs with neurodevelopmental conditions (NDCs) and psychiatric conditions, but previous ...

Novel murine closed‐loop auditory stimulation paradigm elicits macrostructural sleep benefits in neurodegeneration

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Boosting slow‐wave activity (SWA) by modulating slow waves through closed‐loop auditory stimulation (CLAS) might provide a powerful non‐pharmacological tool to investigate the link between sleep and neurodegeneration. Here, we established mouse CLAS (mCLAS)‐mediated SWA enhancement and explored its effects on sleep deficits in neurodegeneration,

Phase-resolved Spectroscopy of Low-frequency Quasiperiodic Oscillations from the Newly Discovered Black Hole X-Ray Binary Swift J1727.8-1613

open access: yesThe Astrophysical Journal
Low-frequency quasiperiodic oscillations (LFQPOs) are commonly observed in X-ray light curves of black hole X-ray binaries (BHXRBs); however, their origin remains a topic of debate.

NREM Sleep Oscillations Are Associated With Anxiety and Negative Affect in Young Adults

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Non‐rapid eye movement sleep (NREM) oscillations are critical for cognitive and affective processing. While several studies link anxiety and depression symptoms to sleep quality, a critical gap remains in elucidating the role of NREM physiology in sleep‐dependent processing of affect and anxiety symptoms. The goals of the present study were to
