Bounded real lemmas for positive descriptor systems [PDF]
, 2015 A well known result in the theory of linear positive systems is the existence of positive definite diagonal matrix (PDDM) solutions to some well known linear matrix inequalities (LMIs).

Positive feedback, memory, and the predictability of earthquakes [PDF]
Proceedings of the National Academy of Sciences, 2002 We review the “critical point” concept for large earthquakes and enlarge it in the framework of so-called “finite-time singularities.” The singular behavior associated with accelerated seismic release is shown to result from a positive feedback of the seismic activity on its release rate.

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics
FEBS Letters, EarlyView.Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

Modeling SMS driven conversion of ceramide to sphingomyelin reveals the existence of a positive feedback mechanism [PDF]
, 2012 In questa tesi presentiamo un modello matematico minimo per la conversione di un ceramide in sfingomielina catalizzata dall'enzima sfingomielina sintasi 1 (SMS1) basato sulle leggi della cinetica chimica.

Positive feedback loops and multistationarity
Discrete Applied Mathematics, 1988 The aim of the paper is to draw the attention of mathematicians to complex systems, frequent in biology and related fields, which comprise multiple feedback loops. Such systems may be described in terms of ordinary differential equations. Since most of these differential equations are non-linear, these systems can not be treated analytically.

FEBS Letters, EarlyView.This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.
