摘要:Very large multiple-input multiple-output (MIMO) technology has a potential of significantly improving the system performance of multi-cell time-division duplexing (TDD) networks, but in practice it is limited by pilot contamination. Different from the traditional channel es...

摘要:Located at the carboxyl terminal of the human papillomavirus major capsid protein L1, helix-5(h5) is crucial to L1 folding and pentamer formation. Site-directed mutagenesis of the leucine residue on site 469 into lysine, alanine, serine and glycine was performed to explore t...

摘要:In this paper we study the stochastic Galerkin approximation for the linear transport equation with random inputs and diffusive scaling. We first establish uniform (in the Knudsen number) stability results in the random space for the transport equation with uncertain scatter...

摘要:Abstract(#br)In this work, we study the semi-classical limit of the Schrödinger equation with random inputs, and show that the semi-classical Schrödinger equation produces O ( ε ) oscillations in the random variable space. With the Gaussian wave packet transform, the origina...

摘要:Abstract(#br)We develop Random Batch Methods for interacting particle systems with large number of particles. These methods use small but random batches for particle interactions, thus the computational cost is reduced from O ( N 2 ) per time step to O ( N ) , for a system w...

摘要:Abstract(#br)We review the Lyapunov functional method for linear ODEs and give an explicit construction of such functionals that yields sharp decay estimates, including an extension to defective ODE systems. As an application, we consider three evolution equations, namely th...

摘要:Abstract(#br)The thermal problems in the underhood are serious in the integrated thermal management of electric vehicles. The interaction of the heat dissipation components in the underhood affects the heat exchange and working performance, which affects its driving range and saf...

摘要:Abstract(#br)We present a local sensitivity analysis for the hydrodynamic Cucker-Smale (HCS) model with random inputs. In the absence of random inputs, the HCS model was derived as a macroscopic model for the emergent dynamics of the CS flocking ensemble from the kinetic CS model...

摘要:Abstract(#br)In this paper we consider a kinetic-fluid model for disperse two-phase flows with uncertainty. We propose a stochastic asymptotic-preserving (s-AP) scheme in the generalized polynomial chaos stochastic Galerkin (gPC-sG) framework, which allows the efficient comp...

摘要:Abstract(#br)In this paper, we develop an Asymptotic-Preserving (AP) stochastic Galerkin scheme for the radiative heat transfer equations with random inputs and diffusive scalings. In this problem the random inputs arise due to uncertainties in cross section, initial data or...
