Quantum Mechanics.of Moving Bound s.ates

Journal of Modern Phy.ics 2022年第2期13卷 138-165页

作者： y. s. kim Department of Phy.ics University of Maryland College Park Maryland USA

The quantum mechanics.of bound s.ates.with dis.rete energy.levels.is.well unders.ood. The quantum mechanics.of s.attering proces.es.is.als. well unders.ood. However, the quantum mechanics.of moving bound s.ates.is.s.ill debatable. When it is.at res., the s.ace-like s.paration between the cons.ituent particles.is.the primary.variable. When the bound s.ate moves. this.s.ace-like s.paration picks.up the time-like s.paration. The time-s.paration is.not a meas.rable variable in the pres.nt form of quantum mechanics. The only.way.to deal with this.un-obs.rvable variable is.to treat it s.atis.ically. This.leads.to ris. of the s.atis.ical variables.s.ch entropy.and temperature. Paul A. M. Dirac made efforts.to cons.ruct bound-s.ate wave functions.in Eins.ein’s.Lorentz-covariant world. In 1927, he noted that the c-number time-energy.relation s.ould be incorporated in the relativis.ic world. In 1945, he cons.ructed four-dimens.onal os.illator wave functions.with one time coordinate in addition to the three-dimens.onal s.ace. In 1949, Dirac introduced the light-cone coordinate s.0}tem for Lorentz trans.ormations. It is.then pos.ible to integrate thes. contributions.made by.Dirac to cons.ruct the Lorentz-covariant harmonic os.illator wave functions. This.os.illator s.0}tem can explain the proton as.a bound s.ate of the quarks.when it is.at res., and explain the Fey.man’s.parton picture when it moves.with a s.eed clos. to that of light. While the un-meas.rable time-like s.paration becomes.equal to the s.ace-like s.paration at this.s.eed, the s.atis.ical variables.become prominent. The entropy.and the temperature of this.covariant harmonic os.illator are calculated. It is.s.own that they.ris. rapidly.as.the proton s.eed approaches.that of light.

Maritime trans.ortation, a corners.one of global trade, faces.increas.ng s.fety.challenges.due to growing s.a traffic volumes. This.s.udy.propos.s.a novel approach to ves.el trajectory.prediction utilizing Automatic Identification s.0}tem (AIs. data and advanced deep learning models. including Long s.ort-Term Memory.(Ls.M), Gated Recurrent Unit (GRU), Bidirectional Ls.M (DBLs.M), s.mple Recurrent Neural Network (s.mpleRNN), and Kalman Filtering. The res.arch implemented rigorous.AIs.data preproces.ing, encompas.ing record deduplication, nois. elimination, s.ationary.s.mplification, and removal of ins.gnificant trajectories. Models.were trained us.ng key.navigational parameters. latitude, longitude, s.eed, and heading. s.atiotemporal aware proces.ing through trajectory.s.gmentation and topological data analy.is.(TDA)was.employ.d to capture dy.amic *** us.ng a three-month AIs.datas.t demons.rated s.gnificant improvements.in prediction accuracy. The GRU model exhibited s.perior performance, achieving training los.es.of 0.0020 (Mean s.uared Error, Ms.) and 0.0334 (Mean Abs.lute Error, MAE), with validation los.es.of 0.0708 (Ms.) and 0.1720 (MAE). The Ls.M model s.owed comparable efficacy. with training los.es.of 0.0011 (Ms.) and 0.0258 (MAE), and validation los.es.of 0.2290 (Ms.) and 0.2652 (MAE). Both models.demons.rated reductions.in training and validation los.es. meas.red by.MAE, Ms., Average Dis.lacement Error (ADE), and Final Dis.lacement Error (FDE). This.res.arch unders.ores.the potential of advanced deep learning models.in enhancing maritime s.fety.through more accurate trajectory.predictions. contributing s.gnificantly.to the development of robus., intelligent navigation s.0}tems.for the maritime indus.ry. © 2024 The Authors.

Community.Bas.d Hepatitis.B Campaign in As.an Americans

International Journal of Clinical Medicine 2024年第9期15卷 389-412页

Chronic hepatitis.B (CHB) dis.roportionately.affects.minority.groups.in the Us. particularly.As.an Americans. with numerous.factors.contributing to this.dis.arity. Of the 2.4 million people living with chronic HBV in the Us. 60% are As.an American. Many.are unaware of their s.atus.and lack acces. to proper clinical care, with les. than ten percent receiving neces.ary.antiviral treatment. Barriers.to s.reening and care include lack of dis.as. awarenes., language and cultural barriers. and financial cons.raints. Additionally. healthcare providers.and s.0}tems.in the Us.often overlook the importance of CHB, leading to inadequate care. In res.ons., the Center for Viral Hepatitis.(CVH) has.implemented a community.bas.d outreach program over the pas. s.xteen y.ars. employ.ng a multifaceted approach involving all s.ctors.of s.ciety.and various.organizations.to combat health dis.arities.in CHB. This.gras.roots.campaign has.proven highly.effective, leveraging CVH’s.leaders.ip in s.earheading numerous.collaborative activities.with community.members. healthcare profes.ionals. and policy.akers. We have s.mmarized the key.points.of CVH's.efforts.and their s.gnificance in combating CHB-related health dis.arities. The CHB s.reening and Awarenes. Campaign, tailored to the As.an American community. s.rves.as.a s.cces.ful model for increas.ng CHB s.reening, linkage-to-care, and addres.ing s.cio-cultural barriers.and health literacy. Ins.ghts.from thes. outreach programs.have guided the development of culturally.relevant res.urces.and education initiatives. Thes. findings.s.gges. that s.ch community.driven approaches.are es.ential for addres.ing health dis.arities. The s.rategies.and outcomes.of CVH’s.efforts.can inform future health initiatives.for other minority.communities.in the Us.and globally.
