Type I interferons modulate autophagy to shape gemcitabine response in pancreatic cancer cells
FEBS Open Bio, EarlyView.Type I interferons differentially modulate autophagy and the response of pancreatic cancer cells to gemcitabine. IFNα2b stimulates autophagic flux and protects cells from gemcitabine‐induced cell death, contributing to chemoresistance. In contrast, IFNβ1a inhibits autophagosome formation and enhances gemcitabine‐induced cell death, resulting in ...

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora
FEBS Open Bio, EarlyView.This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.

Estimation of nonlinear surface pressure characteristics of aerofoil: A 0-1 test approach
AIP Advances, 2019 We investigate the nonlinear behaviour of the surface flow over a two-dimensional NACA 2415 airfoil undergoing turbulent inflow having 8.46% TI at Re=3.01×105 using the 0-1 test for chaos.

A posteriori error estimates of spectral method for nonlinear parabolic optimal control problem
Journal of Inequalities and Applications, 2018 In this paper, we investigate the spectral approximation of optimal control problem governed by nonlinear parabolic equations. A spectral approximation scheme for the nonlinear parabolic optimal control problem is presented. We construct a fully discrete

Controllability in nonlinear systems
Journal of Differential Equations, 1973 AbstractIn this paper we obtain an explicit expression for the reachable set for a class of nonlinear systems. This class is described by a chain condition on the Lie algebra of vector fields associated with each nonlinear system. These ideas are used to obtain a generalization of a controllability result for linear systems in the case where ...

Constrained controllability of nonlinear systems [PDF]
Proceedings of the 2003 American Control Conference, 2003., 1995 This paper contains constrained exact local controllability results for nonlinear abstract differential equations. A generalization of the open mapping theorem is used for the sufficient conditions to guarantee controllability. The values of controls are in a convex, closed cone with vertex at 0.
