Integral fixed-time schedules for traffic light control [PDF]

, 2016
In this paper we consider the optimization of integral fixed-time (traffic light) schedules for isolated intersections. Such integral schedule has an integral period duration and, moreover, for this schedule all switches to green, yellow and red are ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Fixed‐time prescribed performance control method for nonlinear systems with unknown time‐varying parameters

IET Control Theory & Applications
In this study, it is considered that the question of adaptive tracking control of nonlinear systems containing unknown time‐varying parameters. To optimize the control effect, a fixed‐time control strategy is adopted, in which the upper bound of the ...

Finite/Fixed-Time Synchronization for Stochastic Multilayer Networks With Pinning Control

IEEE Access
In recent years, there has been a strong focus on the stability and control of stochastic networks, particularly single-layer networks. However, with the emergence of multi-layer networks, the research in this area has expanded significantly. Multi-layer

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
