In this paper, we introduce the notion of the ideal-stable rangeone condition for exchange rings. Some characterizations for this condition are given. Moreover,
The Riemann problem for zero-pressure flow in gas dynamics in one dimension and two dimensions is investigated. Through studying the generalized Rankine-Hugonio
In this paper, we study the differentiable structure of theω-subset of Sp(2n), which is formed by all matrices in Sp(2n) possessing ω as an eigenvalue, for ω
The relationship between the electronic structure of FCC phase in Fe-Mn-Si alloy and itsstability has been studied by using the discrete variational method base
Stochastic neural networks are usually built by introducing random fluctuations into the network. A natural method is to use stochastic connections rather than
Polyethylene terephthalate (PET) has been modified by Ag, Ti, Cu and Si ion implanta-tion with a dose ranging from 1 × l016 to 2 x 1017 ions/cm2 using a metal
