Periodic Boundary Value Problems for Functional Differential Equations with Impulses

open access: yesJournal of Mathematical Analysis and Applications, 1997
The author obtains existence results for periodic solutions of functional differential systems with impulses. He makes use of the coincidence degree theory and of the notions of strict bounded set and guiding function adapted to the impulsive case. When the impulsive effects are absent, the results reduce to some theorems by \textit{J.

Integral Input-to-State Stability of Nonlinear Time-Delay Systems with Delay-Dependent Impulse Effects

open access: yes, 2020
This paper studies integral input-to-state stability (iISS) of nonlinear impulsive systems with time-delay in both the continuous dynamics and the impulses. Several iISS results are established by using the method of Lyapunov-Krasovskii functionals.

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

open access: yesAdvanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Peano Theorems for Pedjeu–Ladde-Type Multi-Time Scale Stochastic Differential Equations Driven by Fractional Noises

open access: yesMathematics
This paper examines fractional multi-time scale stochastic functional differential equations that, in addition, are driven by fractional noises. Based on a specially crafted fixed-point principle for the so-called “local operators”, we prove a Peano-type

Existence for neutral impulsive functional differential equations with nonlocal conditions

open access: yesIndagationes Mathematicae, 2009
The authors consider an initial value problem for a neutral functional differential equation with impulses at pre-assigned moments of time and they prove existence and uniqueness results concerning the solutions of the corresponding integral equation and the solutions of the differential system itself.

Stochastic differential games involving impulse controls and double-obstacle quasi-variational inequalities

open access: yes, 2012
We study a two-player zero-sum stochastic differential game with both players adopting impulse controls, on a finite time horizon. The Hamilton-Jacobi-Bellman-Isaacs (HJBI) partial differential equation of the game turns out to be a double-obstacle quasi-
