Uses of the Popov Stability Criterion for Analyzing Global Asymptotic Stability in Power System Dynamic Models

open access: yes
Stability studies remain a crucial aspect of power systems dynamic analysis, and are typically explored in three main categories: numerical methods, linearization techniques, or direct methods, which utilize Lyapunov energy functions.

Extension of Popov Absolute Stability Criterion to Nonautonomous Systems with Delays [PDF]

open access: yes, 1999
Projet SOSSOThis paper extends in a simple way the classical absolute stability Popov criterion to multivariable systems with delays and with time-varying memoryles- s nonlinearities subject to sector conditions.

Can There Be Too Much Finance? A Complex Answer to a Simple Question

open access: yesThe Manchester School, Volume 94, Issue 6, Page 592-601, December 2026.
ABSTRACT This paper provides a critical review of the Too Much Finance literature, both in its academic contribution and as response to the earlier finance and growth literature. We describe the academic origins and development of the finance and growth literature and discuss pitfalls with the commonly used indicators of financial development.

Control Design Based on Generalized Lur'e Lyapunov Functions for Sampled‐Data Lur'e Systems

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 36, Issue 16, Page 7450-7463, 10 November 2026.
ABSTRACT This article addresses the synthesis of stabilizing control laws for aperiodic sampled‐data Lur'e systems. Based on a hybrid system representation of the closed‐loop system and a timer‐dependent generalized Lur'e–Postnikov type Lyapunov function, stabilization conditions are obtained by separating decision variables with the application of two

Assessment of Growth in Cardio‐Facio‐Cutaneous Syndrome

open access: yesAmerican Journal of Medical Genetics Part A, Volume 200, Issue 11, Page 2443-2453, November 2026.
ABSTRACT Cardio‐facio‐cutaneous (CFC) syndrome is a rare, multiple congenital anomaly disorder in which individuals commonly experience faltering growth; however, systematic analysis of growth parameters in this disorder has not been performed. We recruited 69 participants with CFC through CFC International and collected data on assessing height ...

Effects of an Inpatient Program on Medication Errors in Hospitalized People with Parkinson's Disease

open access: yesAnnals of Neurology, Volume 100, Issue 5, Page 1068-1079, November 2026.
Objective Hospitalized people with Parkinson's disease (PwP) face increased risks of medication errors and discharge to non‐home settings, both of which are associated with adverse outcomes. This study assessed differences in medication error rates and discharge outcomes before and after implementation of a dedicated inpatient program for hospitalized ...

The SIR Model in a Moving Population: Propagation of Infection and Herd Immunity

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 11, Page 2375-2429, November 2026.
ABSTRACT In a collection of particles performing independent random walks on Zd$\mathbb {Z}^d$ we study the spread of an infection with SIR dynamics. Susceptible particles become infected when they meet an infected particle. Infected particles heal and are removed at rate ν$\nu$.

Cell Surface Markers Identify Astrocyte Subpopulations in the Adult Hippocampus With a Heterogeneous Response to Aging

open access: yesGlia, Volume 74, Issue 11, November 2026.
ATP1B2 and GLAST identify two astrocyte subpopulations in the hippocampus with distinct molecular signatures. Transcriptomic shifts during aging differ between both subpopulations. Aged ATP1B2+ astrocytes rewire their metabolism while double‐positive aged astrocytes display a reduced synaptogenic capability.
