Query: On Some Recent Progress in the Vlasov-Poisson-Boltzmann System with
  Diffuse Reflection Boundary   We discuss some recent development on the Vlasov-Poisson-Boltzmann system in
bounded domains with diffuse reflection boundary condition. In addition we
present a new regularity result when the particles are surrounded by conductor
boundary.
