The analytical propagation formulae of twisted partially coherent beams in strongly nonlocal nonlinear media (SNNM) are derived. It is shown that a twisted partially coherent soliton (TPCS) can be formed in SNNM when the critical power arrives. The a

The equivalent B-integral phase screen (EBPS) method of numerical simulation is proposed to study the propagation of a high-power laser beam in the atmosphere along a slant path, and the computational accuracy and efficiency of the EBPS method are co

Background: Coronary collateral circulation (CCC) plays a vital role in the myocardial blood supply, especially for ischemic myocardium. Evidence suggests that the visfatin and 25-hydroxyvitamin D 3 [25(OH)D 3 ] levels are related to the degree and i

The Kerr self-focusing and group-velocity dispersion (GVD) effects play important roles when a high-power pulsed laser beam propagates from the ground through the nonlinear and dispersive atmosphere to space orbits. For an annular pulsed laser beam,

KNN-Based outlier detection over IoT streaming data is a fundamental problem, which has many applications. However, due to its computational complexity, existing efforts cannot efficiently work in the IoT streaming data. In this paper, we propose a n

In order to control the distribution characteristics of the far-field ring-shaped array, we introduce a new light source to produce adjustable far-field distribution by the method of weight function superposition. It has been shown that, by changing

The chirp characteristics and the effect of chirp on the beam quality of laser pulses propagating from the ground through the atmosphere to the space orbit are studied. The analytical expressions of the additional chirp caused by group-velocity dispe
