Stability analysis and soliton solu.ions of the(1+1)-dim..sional nonlinear chiral Schr?dinger equ.tion in nu.lear physics

Com..nications in Theoretical Physics 2024年第9期76卷 1-15页

The nonlinear Schr?dinger equ.tion equ.tion is one of the m..t im..rtant physical m..els u.ed in optical fiber theory to explain the transm..sion of an optical soliton. The field of chiral soliton propagation in nu.lear physics is very interesting becau.e of its nu.0}ou. applications in com..nications and u.tra-fast signal rou.ing system.. The (1+1)-dim..sional chiral dynam..al stru.tu.e that describes the soliton behaviou. in data transm..sion is dealt with in this work u.ing a variety of in-depth analytical techniqu.s. This work has applications in particle physics, ionised science, nu.lear physics, optics, and other applied m..hem..ical sciences. We are able to develop a variety of solu.ions to dem..strate the behaviou. of solitary wave stru.tu.es, periodic soliton solu.ions, chiral soliton solu.ions, and bell-shaped soliton solu.ions with the u.e of applied techniqu.s. m..eover, in order to verify the scientific calcu.ations, the stability analysis for the observed solu.ions of the governing m..el is taken into consideration. In addition, the3-dim..sional, contou., and 2-dim..sional visu.ls are su.plied for a better u.derstanding of the behaviou. of the solu.ions. The em..oyed strategies are dependable, u.com..icated, and effective; yet have not been u.ilised with the governing m..el in the literatu.e that is now accessible. The resu.ting ou.com.. have im..essive applications across a large nu.0}r of stu.y areas and com..tational physics phenom..a representing real-world scenarios. The m..hods applied in this m..el are not u.ilized on the given m..els in previou. literatu.e so we can say that these describe the novelty of the work.

A 67 years old patient with AD was selected for this stu.y becau.e the patient has been su.fering from..epression, dem..tia, and physical dysfu.ction along with som..other health conditions like diabetes and hypertension. Before starting intervention, a baseline assessm..t was done throu.h the Beck Depression Inventory (BDI) tool, the m..i-Cog Scale, and the Berg Balance Scale (BBS). The patient received 12 sessions of AOT along with u.u.l physiotherapy interventions thrice a week for fou. weeks, which inclu.ed 45 m..u.es of each session. After fou. weeks of intervention, the patient dem..strated significant im..ovem..t in depression, cognition, and balance, whereas the BDI score declined from..oderate 21/63 to m..d 15/63 level of depression. The m..i-Cog score im..oved from../5 to 4/5, and the BBS score increased from..8/56 to 37/56.

Introdu.tion: Bangladesh has experienced rem..kable growth in Rm..over the past 25 years. With the knitwear indu.try providing m..e than 4 m..lion direct jobs, providing better occu.ational health and safety of workers rem..ns a challenge. Aim..f the stu.y: The aim..f the stu.y was to analyze the disease bu.den of a Rm..factory, and to highlight occu.ational health risks. m..hods: A cross-sectional stu.y design was em..oyed for this analysis. A 17-m..th data entry (Janu.ry 2020 - m.. 2021) was gathered from..he factory in-hou.e clinic. The socio-dem..raphic and clinical diagnosis entries of 8421 entries were analyzed. Resu.t: The popu.ation of the factory workers is 5370, where 40% (2148) are fem..e workers and 60% (3222) are m..e workers. The m..n age of respondents is 30 years, with a SD of ±7 years. Am..g the chief com..aints, the m..t com..n was vom..ing (14%;2262) fever (14%;2247), ru.ny nose (11%;1842), cou.h (9%;1465), and loose m..ion (8%;1364). In the diagnosis categories, gastrointestinal diseases were m..e predom..antly diagnosed (35%;2978), followed by viral fever (21%;1772), neu.ological diseases (16.5%;1389) and m..cu.oskeletal disorders (9%;768). The average cost of m..icine for each respondent is BDT 36. The factory covered costs of all m..ication for 99% (8380) of respondents. Only 0.5% (37) was referred to a tertiary hospital for fu.ther evalu.tion. Conclu.ion: Garm..ts workers su.fer m..tly from..ong-term..ccu.ational health hazards. Factory owners and policy m..ers can contribu.e in variou. ways to im..oving prim..y healthcare options for workers.
