The positivity-preserving property is an important and challenging issue for the numerical solution of radiative transfer equations. In past few decades, different techniques have been proposed to guarantee positivity intensity in several schemes; however it difficult maintain both high order accuracy positivity. discontinuous Galerkin (DG) finite element method a which widely used solve neutron/photon equations, due its distinguished advantages such as accuracy, geometric flexibility,...

Abstract In, Maire developed a class of cell-centered Lagrangian schemes for solving Euler equations compressible gas dynamics in cylindrical coordinates. These use node-based discretization the numerical fluxes. The control volume version has several distinguished properties, including conservation mass, momentum and total energy compatibility with geometric law (GCL). However it also limitation that cannot preserve spherical symmetry one-dimensional flow. An alternative is given to first...

Abstract Ca 2+ channels are essential to cell birth, life, and death. They can be externally activated by optogenetic tools, but this requires robust introduction of exogenous genes for expression photosensitive proteins in biological systems. Here we present femtoSOC, a method direct control solely ultrafast laser without the need tools or any other reagents. Specifically, focusing scanning wavelength-tuned low-power femtosecond pulses on plasma membrane multiphoton excitation, directly...

Abstract Lagrangian methods are widely used in many fields for multi-material compressible flow simulations such as astrophysics and inertial confinement fusion (ICF), due to their distinguished advantage capturing material interfaces automatically. In some of these applications, multiple internal energy equations those electron, ion radiation involved. the past decades, several staggered-grid based schemes have been developed which designed solve equation directly. These can be easily...
