Robust Bounds on the Eigenvalues of Linear Systems With Delays and Their Applications in Stability Analysis

International Journal of Robust and Nonlinear Control, Volume 35, Issue 16, Page 6636-6651, 10 November 2025.
ABSTRACT We review some known bounds on the eigenvalues of a matrix and use similar techniques to derive bounds for the class of nonlinear eigenproblems and, as a special case, the eigenvalues for LTI systems with delays. We present two classes of results.

Output feedback robust stabilization of distributed‐order systems

Asian Journal of Control, Volume 27, Issue 6, Page 2685-2693, November 2025.
Abstract This paper addresses the challenge of robust fast stabilization for a class of dynamical systems characterized by slow and ultra‐slow dynamics. The system model is approximated using a distributed‐order derivative of the measured output, which captures the influence of the control input, system dynamics, and external disturbances.

Topographic Variation in Human Neurotransmitter Receptor Densities Explains Differences in Intracranial EEG Spectra

Human Brain Mapping, Volume 46, Issue 16, November 2025.
Using generative models, we demonstrated that oscillatory neuronal population activity is shaped by the distribution of neurotransmitter receptors. This modelling furnishes an atlas of normative parameter values, which constitute neurobiologically informed priors for in silico (e.g., Digital Twin) characterisation of normal and disordered brain ...

Equity in Health Policy for Persons With Disabilities in Brazil: Spatial Distribution of Specialised Rehabilitation Centres

The International Journal of Health Planning and Management, Volume 40, Issue 6, Page 1279-1288, November 2025.
ABSTRACT Objective To analyse the spatial distribution of Specialised Rehabilitation Centres (CERs) in Brazil, considering the prevalence of persons with disabilities (PWD), socioeconomic factors, and health financing. Methods An ecological study design was employed, using descriptive and Bayesian spatial regression analyses on data from 438 health ...

Investigation of the Effect of Isotonic Drinks on Quantitative MRI Markers of the Liver and Spleen

NMR in Biomedicine, Volume 38, Issue 11, November 2025.
Dynamic models relating liver and spleen T1 to three different amounts of isotonic drinks (0.5, 1.0, and 1.5 L) are described, and the dependence of liver T1, stiffness, volume, and fat fraction on isotonic drinks is discussed. Only T1 prolongation bore clinical significance, and the time constants of dynamic models were dependent only on the volume of

Quantifying Benthic Biolayer Contributions to Whole‐Stream Reactivity by Unifying Surface and Subsurface Observations: Field Evidence and Theory

Water Resources Research, Volume 61, Issue 11, November 2025.
Abstract The benthic biolayer is a shallow zone of reactive streambed sediments, widely believed to contribute disproportionately to whole‐stream reactions such as aerobic respiration and contaminant transformation. Quantifying the relative contribution of the biolayer to whole‐stream reactions remains challenging because it requires that hyporheic ...
