Abstract: Due to its future use in communication area, nonlocal spatial optical soliton has been a hot research topic recently. However, because of its special border condition, little research has been done on spatial dark solitons especially on its linear stability. In this paper, a method to analyze linear stability of nonlocal spatial dark soliton is put forward, moreover a numerical simulation and analysis is done on the linear stability of (1+1)-dimensional fundamental and second-order dark soliton in thermal nonlinear medium. Numerical results show that (1+1)-dimensional fundamental nonlocal dark solitons are always stable in their entire existence domain, while second-order dark solitons are oscillatorily unstable and the width of unstable domain depends on propagation constant and nonlocality degree of thermal nonlinear medium. The propagation graphs of initial input with noise addition confirms the correctness of linear stability analysis results.

Multi-direction Propagation of the Tropical Convection during the Onset Period of the South China Sea Summer Monsoon

Abstract: Based on the daily outgoing long-wave radiation(OLR) dataset from NCEP/NCAR during 1979-2004,the features of the zonal and meridional propagations of the tropical convection during the onset period of the South China Sea(SCS) summer monsoon(SCSSM) are analyzed in this paper.Results indicate that the directions of both the zonal propagation and the meridional counterpart are quite different.For example,for the zonal propagation,the deep convection can propagate either from the Bay of Bengal(BOB) to SCS,or fr...

Abstract: The interaction between dark solitons in nonlocal self-defocusing media is investigated. Numerical results show that there is a critical condition for interaction between dark solitons in nonlocal self-defocusing medium. Under the critical condition, dark solitons will neither attract nor repell each other because the attractive force and repulsive force between them are identical. Beyound the critical condition, dark solitons may attract or repell each other depending on the nonlocalization degree and distance between them. The value of the critical condition is found.

Abstract: In this paper, we investigate spatial dark solitons in nonlocal nonlinear media. Based on the nonlocal nonlinear Schr dinger equation and the diffusion equation, the numerical solutions with different propagation constants are obtained by using the Newton iterative method. And it is found that there exist dark soliton solutions .and the relation between the width of dark soliton and the degree of nonlocality for any propagation constant under arbitrary nonlocal degrees different propagation constants. In experiments, we observe the formation of the spatial dark solitons in the solution of dye. The influence of Gaussian background on dark solitons is also discussed, and the numerical results are in agreement with the experimental results.

Abstract: 利用光谱重置法在数值上求解非局域非线性薛定谔方程,快速准确地计算出非局域非线性介质中空间光孤子的波形,并得到在不同非局域程度下形成孤子的临界功率和临界束宽的关系.研究结果表明,在任意非局域程度条件下都可以形成稳定的空间光孤子.在响应函数不同时分别与解析解进行对比,发现数值解和解析解只有在强非局域和弱非局域这两种极限条件下是一致的,并给出了对应解析解的有效范围.

Abstract: 肝性脑病(Hepatic Encephalopathy, HE)是由严重肝功能障碍或门体分流引起的脑功能紊乱，主要表现为意识障碍、记忆力下降以及注意力不集中等缺陷的神经或精神方面的改变。常见于肝硬化、急性肝衰竭等患者。基于肝性脑病的发病机制尚未明确且药物治疗旨在减少氨的产生和吸收，改善症状并预防复发存在一定的局限性，并对患者的经济条件有较大的损耗。因此，笔者从中医和西医两个方向对治疗肝性脑病的药物进行综述，为寻找有效且符合患者经济条件的药物提供重要临床参考依据。
Hepatic encephalopathy (HE) is a disorder of brain function resulting from severe hepatic insufficiency or portosystemic shunt, primarily manifested as neurological or psychiatric alterations including impaired consciousness, decreased memory, and inattention. It is commonly seen in patients with conditions such as liver cirrhosis and acute liver failure. Given that the pathogenesis of HE remains unclear and that pharmacological treatments, aimed at reducing ammonia production and absorption, alleviating symptoms, and preventing recurrence, have certain limitations and impose significant financial burdens on patients, the author conducted a comprehensive review of medications used in the treatment of HE from both traditional Chinese medicine (TCM) and western medicine perspectives. This review provides important clinical reference for identifying effective treatments that are also economically viable for patients.
