Sampled-Data-Based Local Stability of Neutral Time-Delay Systems With Actuator Saturation
IEEE AccessIn this work, the local stability issue of neutral delay system with actuator saturation under sampled-data controller is studied. Firstly, considering the influence of actuator saturation on the system, the sampled-data controller with variable sampling

An improved fragmentation approach to sampled-data synchronization of chaotic Lur'e systems
, 2018 This paper considers the sampled-data synchronization problem for two identical chaotic Lur'e systems. Under aperiodic samplings, the output of the chaotic Lur'e systems is available only at sampling instants. An improved fragmentation approach

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Event-Triggered Sampled-Data Iterative Learning Control for Fractional-Order Cyber-Physical Systems
Fractal and FractionalThis paper investigates the output synchronization of fractional-order cyber-physical systems (FOCPSs) under communication constraints. To address limited bandwidth and high transmission costs, an event-triggered encoding-decoding sampled-data iterative ...

FEBS Letters, EarlyView.Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Determining the intersample response of state feedback control systems using boundary value problems
Boundary Value ProblemsThis paper investigates intersample dynamics, a key aspect of sampled-data systems, as the controlled processes are usually physical systems. We present a novel, boundary value problem-based method to reconstruct the continuous-time response from the ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...
