Decentralized Discrete-Time Formation Control for Multirobot Systems
Discrete Dynamics in Nature and Society, 2013 Inspired from the collective behavior of biological entities for the group motion coordination, this paper analyzes the formation control of mobile robots in discrete time where each robot can sense only the position of certain team members and the group

Model‐free adaptive integral sliding mode constrained control with modified prescribed performance
IET Control Theory & Applications, 2023 In this work, a novel model‐free adaptive integral sliding model constrained control strategy with modified prescribed performance is proposed for nonlinear nonaffine systems via full‐form dynamic linearization (FFDL).

Computation of H-infinity norm of linear discrete-time periodic systems [PDF]
, 2006 We propose an efficient an numerically reliable procedure for the computation of H-infinity norm of discrete-time linear periodic systems. The new procedure is general being applicable to both standard as well as descriptor periodic systems with time ...

Small RNA pathways in mammalian oocytes
FEBS Open Bio, EarlyView.Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Robust Finite-Time Stabilization for Uncertain Discrete-Time Linear Singular Systems
IEEE Access, 2020 This paper considers the robust finite-time stabilization problem for a class of discrete-time linear singular systems with norm-bounded parameter uncertainties. With the introduction of an additional matrix to describe the algebraic relationship between

FEBS Open Bio, EarlyView.TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

H- Index for Stochastic Linear Discrete-Time Systems
Discrete Dynamics in Nature and Society, 2015 This paper discusses the H- index problem for stochastic linear discrete-time systems. A necessary and sufficient condition of H- index is given for such systems in finite horizon.

A new framework for consensus for discrete-time directed networks of multi-agents with distributed delays [PDF]
, 2012 Copyright @ 2012 Taylor & FrancisIn this article, the distributed consensus problem is considered for discrete-time delayed networks of dynamic agents with fixed topologies, where the networks under investigation are directed and the time-delays involved
