The effect of aus.enitization heat treatment on magnetic properties.was.examined by means.of M6s.bauer s.ectros.opy on an Fe-40wt%Ni-2wt%Mn alloy. The morphology of the alloy was.obtained by us.ng s.anning electron micros.opy （s.M） under different heat treatment conditions. The magnetic behavior of the non heat-treated alloy is.ferromagnetic. A mixed magnetic s.ructure including both paramagnetic and ferromagnetic s.ates.was.obtained at 800℃ after 6 and 12 h heat treatments. In addition, the magnetic s.ructure of the heat-treated alloy at 1150~C for 12 h was.ferromagnetic. With the volume fraction changing, the effective hyperfine field of the ferromagnetic aus.enite phas. and is.mery s.ift values.were als. determined by Mts.bauer s.ectros.opy.

We calculate the s.attering cros. s.ction of an electron with res.ect to the s.ontaneous.y produced las.r radiation in the firs. free-electron las.r （FEL） with quantum-wiggler electrodynamics.（QWD）. The cros. s.ction is.1016 times.the Thoms.n cros. s.ction, confirming the res.lt obtained by a previous.analys.s.of the experimental data. A QWD calculation s.ow that s.ontaneous.emis.ion in an FEL us.ng only an electric wiggler can be very s.rong while amplification through net s.imulated emis.ion is.practically negligible.

We derive the cros. s.ction of s.attering through the three-quantum interaction of an electron with the incident las.r field, the emitted photon, and an axial electros.atic field produced by the magnetic wiggler in the magnetic wiggler acting as.the s.le zeroth-order perturbing clas.ical field in the firs. free-electron las.r （FEL）. In the derivation, we apply quantum-wiggler electrodynamics.（QWD）. We find that this.s.attering predominates.the us.al two-quantum s.attering. The output power of s.ontaneous.free-electron two-quantum s.ark emis.ion driven by the above electros.atic field attenuated by the three-quantum s.attering agrees.within a factor of 10 with the meas.red power in the cas. of the firs. FEL.

We cons.der the s.s.ematics.of α-decay half-lives.of s.per-heavy nuclei vers.s.the decay energy and the total α-kinetic energy. We calculate the half-lives.us.ng the experimental Qα values. The computed half-lives.are compared with the experimental data and with exis.ing empirical es.imates.and are found to be in good agreement. Als., we obtain α-preformation factors.from the ratio between theoretical and experimental res.lts.for s.me s.per- heavy nuclei and evaluate the s.andard deviation. The res.lts.indicate the acceptability of the approach.

Thermo-mechanical coupling in s.ape memory alloys.is.a very complicated phenomenon. The heat generation/abs.rption during forward/revers. trans.ormation can lead to temperature-dependent variation of its.mechanical behavior in the forms.of s.perelas.icity and s.ape memory effect. however, unlike the us.al as.umption, s.ow loading rate cannot guarantee an is.thermal proces.. A two-dimens.onal thermo-mechanically coupled algorithm is.propos.d bas.d on the original model of Lagoudas.to efficiently model both s.perelas.icity and s.ape memory effects.and the influence of various.s.rain rates. as.ect ratios.and boundary conditions. To implement the coupled model into a finite element code, a numerical s.aggered algorithm is.employed. A number of s.mulations.are performed to verify the propos.d approach with available experimental and numerical data and to as.es. its.efficiency in s.lving complex s.A problems.

Background: Cardiovas.ular dis.as. (CVD) affects.the heart and blood ves.els. Older people are cons.derably more likely to s.ffer from a heart attack or s.roke or to develop coronary heart dis.as. (commonly called heart dis.as.) and heart failure than younger people. Caring for older patients.with cardiac conditions.is.markedly different from caring for younger patients.with the s.me diagnos.s. Objective: This.s.udy aimed to explore the characteris.ics.and prevalence of CVD and its.as.ociated comorbidities.in older patients. Methods. This.s.udy reviewed the medical files.of all patients.aged 65 years.and older with CVD. Data s.ch as.s.ciodemographic characteris.ics.and CVD findings.were collected from 1614 patients.with CVD. Des.gn and s.tting: s.ngle-center retros.ective cros.-s.ctional s.udy. s.bjects. Almos. two-thirds.(1044, 64.7%) of the patients.were male, and one-third (570, 35.3%) were female;all had various.comorbidities. Res.lts. Two main comorbidities.as.ociated with CVD were hypertens.on (hTN) (1092, 67.7%) and diabetes.mellitus.(DM) (927, 57.4%). The mean number of comorbidities.as.ociated with CVD was.2.61 (±1.1 s.), with a higher average in males.than in females.(2.74 [±1.07] vs. 2.54 [±1.06]). Conclus.on: Up to s.x as.ociated comorbidities.were found in older patients.with CVD, mos.ly with three comorbidities.per patient. Males.accounted for two-thirds.of the overall s.udy population. hTN and diabetes.mellitus.were the main CVD-as.ociated comorbidities. Furthermore, almos. 95.2 patients.were reduced every 5 years.of age progres.ion.

We s.udy the s.und perturbation of a rotating acous.ic black hole in the pres.nce of a dis.lination. The radial part of the mas.les. Klein-Gordon equation is.written into a heun form, and its.analytical s.lution is.obtained. Thes. s.lutions.have an explicit dependence on the parameter of the dis.lination. We obtain the exact hawking-Unruh radiation s.ectrum.
