Abstract

We study the nonlinear localized modes in two-component Bose-Einstein condensates with parity-time-symmetric Scarf-II potential, which can be described by the coupled Gross-Pitaevskii equations. Firstly, we investigate the linear stability of the nonlinear modes in the focusing and defocusing cases, and get the stable and unstable domains of nonlinear localized modes. Then we validate the results by evolving them with 5% perturbations as an initial condition. Finally, we get stable solitons by considering excitations of the soliton via adiabatical change of system parameters. These findings of nonlinear modes can be potentially applied to physical experiments of matter waves in Bose-Einstein condensates.

Efficacy and safety of Shenkang injection in the treatment of chronic renal failure

“…Main efficacy indicators: total efficiency: refer to the Guidelines for Clinical Research of New Chinese Medicine Drugs , [20] total effective rate = (effective number + effective number)/total number of patients ×100%. significant effect: clinical symptom score decreased ≥60%, Ccr increased ≥20% or Scr decreased ≥20%; effective: 30%≤ clinical symptom score decreased <60%, 10%≤ Ccr increased <20% or 10%≤ Scr decreased <20%; stable: clinical symptom score decreased by <30%, Ccr increased by <10% or Scr decreased by <10%; invalid: the clinical symptoms were not improved or aggravated, the clearance rate of Ccr decreased, and the Scr increased.…”

Morphology Prediction Methods and Their Applications in Energetic Crystals

“…In the case of high supersaturation, the F-faces grow through the 2D nucleation, and the growth rate can be approximated as 31 (2) where F is defined as (3) in which c n is the factor defined as c n � P/A 1/2 , where P is the perimeter of a nucleus and A is the area; and ϕ e is the effective edge energy. The absolute face growth rate can be calculated by the Lovette-Doherty equation 31 (4) where σ* is an arbitrary low supersaturation at which all faces are grown in the spiral growth pattern and σ 2D,hkl is the onset supersaturation for the 2D nucleation.…”

“…It is not only intrinsically determined by molecular structure and molecular stacking structures but also significantly governed by crystallization conditions, such as temperature, solvent, agitation, seed, container size and shape, etc. 2 The crystal morphology of an energetic compound governs many fundamental properties and use behaviors, including energy, sensitivity, stability, processing performance, and so forth, as demonstrated in Figure 1. For example, when the morphology of an energetic crystal changes from spherical to ellipsoidal, prism-like, tetrahedral, and needle-like, its mechanical sensitivity increases, as chemical decomposition and hot spot formation proceed more and more readily on edges and corners.…”

“…Crystal morphology refers to the geometric shape of the crystal and results from the difference in growth rate of crystal faces. It is not only intrinsically determined by molecular structure and molecular stacking structures but also significantly governed by crystallization conditions, such as temperature, solvent, agitation, seed, container size and shape, etc . The crystal morphology of an energetic compound governs many fundamental properties and use behaviors, including energy, sensitivity, stability, processing performance, and so forth, as demonstrated in Figure .…”

Hypoxic‐ischemic brain injury and narcotic drugs administration

“…While it has been reported that enflurane could drive EEG epilepsy-like movement. Moreover, fluothane and enflurane could significantly impair the automatic regulatory mechanism (Huang GY, et al, 2000). It has been found that fluothane, sevoflurane, desflurane, isoflurane all could reduce the volume of cerebral infarction in focal cerebral ischemia, and this protective effect occurs on 1 to 7 days (d) following ischemia (Xiong L, et al, 2003).…”
