NULL CONTROLLABILITY OF NEUTRAL EVOLUTION INTEGRODIFFERENTIAL SYSTEMS WITH INFINITE DELAY
, 2020 We establish a set of sufficient conditions for the controllability of nonlinear neutral evolution integrodifferential systems with infinite delay in Banach spaces. The results are established by using the Sadovskiȋ fixed point theorem and generalize the

Stochastic Lotka-Volterra model with infinite delay
The stochastic Lotka-Volterra system with infinite delay is studied. We show that the solution of such a system is a positive solution without explosion and give the conditions to guarantee stochastic ultimate boundedness of the solution.

Advanced Engineering Materials, EarlyView.A two‐dimensional multiscale finite element analysis framework was established for the first‐generation MoSiBTiC alloy, and the mechanical and fracture‐related parameters of the constituent phases were calibrated through experiments and simulations. The framework provides a basis for analyzing crack propagation behavior in its complex microstructure ...

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing
Advanced Engineering Materials, EarlyView.The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.
