A nonlinear singular perturbation problem

open access: yesAsymptotic Analysis, 2006
Let F(uε)+ε(uε−w)=0 (1) where F is a nonlinear operator in a Hilbert space H, w∈H is an element, and ε>0 is a parameter. Assume that F(y)=0, and F′(y) is not a boundedly invertible operator. Sufficient conditions are given for the existence of the solution to (1) and for the convergence lim ε→0‖uε−y‖=0. An example of applications is considered.

Recent Advances in Laser‐Induced Graphene‐Based Gas Sensors: From Sensing Mechanisms to Biomedical Applications

open access: yesAdvanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...

Lifshitz Transition in Correlated Topological Semimetals

open access: yesAdvanced Science, EarlyView.
Theoretical calculations reveal that in YPtBi and GdPtBi, strong electronic correlations shift topological Dirac nodes away from the Fermi level by forming large hole pockets. This effect is sensitive to temperature and arises from interactions among 4d or 4f electrons, offering insights into Fermi surface engineering in quantum materials.

Synchronization problems for unidirectional feedback coupled nonlinear systems

open access: yes, 2007
In this paper we consider three different synchronization problems consisting in designing a nonlinear feedback unidirectional coupling term for two (possibly chaotic) dynamical systems in order to drive the trajectories of one of them, the slave system,
