Stability of p.c.m. characteristic equations
Electronics Letters, 1966 The stability criteria of an oscillator control system suitable for a network of p.c.m. systems are examined. The system is shown to be stable for a wide range of signal-path delay.

Analysis of a characteristic equation
Journal of Integral Equations and Applications, 1991 The authors investigate a characteristic equation occurring in epidemic models formulated in terms of integro-differential equations, where births and deaths are introduced and the total population size is assumed to be constant. They establish conditions on the two parameters of this equation, under which an equilibrium position is stable.

Molecular Oncology, EarlyView.A comprehensive genomic and proteomic analysis of cervical cancer revealed STK11 and STX3 as a potential biomarkers of chemoradiation resistance. Our study demonstrated EGFR as a therapeutic target, paving the way for precision strategies to overcome treatment failure and the DNA repair pathway as a critical mechanism of resistance.

Electronic Journal of Differential Equations, 2010 We study some properties concerning the asymptotic behavior of solutions to nonautonomous retarded functional differential equations, depending on the knowledge of certain solutions of the associated generalized characteristic equation.

Mordell's equation in characteristic three [PDF]
Bulletin of the Australian Mathematical Society, 1990 Let K be a function field in one variable over a finite field of characteristic three. If a ∈ K is not a cube, we show that the equation y2 = x3 + a has only finitely many solutions x, y ∈ K.

Modeling hepatic fibrosis in TP53 knockout iPSC‐derived human liver organoids
Molecular Oncology, EarlyView.This study developed iPSC‐derived human liver organoids with TP53 gene knockout to model human liver fibrosis. These organoids showed elevated myofibroblast activation, early disease markers, and advanced fibrotic hallmarks. The use of profibrotic differentiation medium further amplified the fibrotic signature seen in the organoids.
