The spectrum of the restriction to an invariant subspace [PDF]

Oper. Matrices 14 (2020) 261-264, 2020
Let $X$ be a Banach space, $A\in B(X)$ and $M$ be an invariant subspace of $A$. We present an alternative proof that, if the spectrum of the restriction of $A$ to $M$ contains a point that is in any given hole in the spectrum of $A$, then the entire hole is in the spectrum of the restriction.

Dynamic Functional Network Connectivity Analysis in Autism Spectrum Disorder: An EEG Study

IEEE Access
Convergent evidence has suggested a significant effect of bumetanide exposure on brain connectivity in patients with autism spectrum disorder (ASD), yet the characteristics of favorable treatment outcome remains largely unknown. In this work, we aimed to

A Look Into the Power of fNIRS Signals by Using the Welch Power Spectral Estimate for Deception Detection

Frontiers in Human Neuroscience, 2021
Neuroimaging technologies have improved our understanding of deception and also exhibit their potential in revealing the origins of its neural mechanism. In this study, a quantitative power analysis method that uses the Welch power spectrum estimation of

SAR Window Functions: A Review and Analysis of the Notched Spectrum Problem [PDF]

, 2002
Imaging systems such as Synthetic Aperture Radar collect band-limited data from which an image of a target scene is rendered. The band-limited nature of the data generates sidelobes, or ''spilled energy'' most evident in the neighborhood of bright point-like objects.

Steroidal MRA Across the Spectrum of Renal Function: A Pooled Analysis of RCTs. [PDF]

JACC. Heart failure, 2022
Mineralocorticoid receptor antagonists (MRAs) are underused in patients with kidney dysfunction, and their efficacy among patients with chronic kidney disease (CKD) is uncertain.The goal of this study was to analyze the efficacy and safety of steroidal MRAs across the spectrum of estimated glomerular filtration rates (eGFRs) in randomized controlled ...

Disrupted Dynamic Functional Connectivity in Distinguishing Subjective Cognitive Decline and Amnestic Mild Cognitive Impairment Based on the Triple-Network Model

Frontiers in Aging Neuroscience, 2021
Background: Subjective cognitive decline and amnestic mild cognitive impairment (aMCI) were widely thought to be preclinical AD spectrum disorders, characterized by aberrant functional connectivity (FC) within the triple networks of the default mode ...

The immunological interface: dendritic cells as key regulators in metabolic dysfunction‐associated steatotic liver disease

FEBS Letters, EarlyView.
Metabolic dysfunction‐associated steatotic liver disease (MASLD) affects nearly one‐third of the global population and poses a significant risk of progression to cirrhosis or liver cancer. Here, we discuss the roles of hepatic dendritic cell subtypes in MASLD, highlighting their distinct contributions to disease initiation and progression, and their ...
