Atomic clocks based on optical frequency transitions are supposed to have great potential to get extreme accuracy.Many optical clocks have shown better accuracy
In jammed static packings,diverse photoelastic tests and numerical simulations have shown that particles are organized into a highly heterogeneous structure.The
Flow separation and recirculation resulted from a sudden constriction in the flow geometry,in the form of a forward-facing step (FFS),play an important role in
Polarization control (PC),which manipulates the polarization state of the photon,is one of the key issues in the field of optical communications and sensing.[1-
First principles calculations based on the density functional theory of the electronic structure,elastic and lattice vibrational properties of orthorhombic CaSh
In the last decade,the femtosecond pulse filamentation in transparent media has been extensively studied by many research groups[1] and made great achievements
A matchingpursuit method based on training an over-complete dictionary is investigated.By using the K-singular value decomposition (K-SVD) algorithm,an over-com
