We argued that the standard fiel. scal.r potential.coul.n’t be widel. used for getting the adequate gal.xies’ curve l.nes and determ.ning the profil.s of dark m.tter their hal.. For discovering the gl.bal.properties of scal.r fiel.s that can describe the observabl. characteristics of dark m.tter on the cosm.l.gical.space and tim. scal.s, we propose the sim.l.st form.of central.sym.etric potential.cel.stial.m.chanical.type, i.e. U(φ) = –μ/φ. It was shown that this potential.al.ows get rather satisfactoril. dark m.tter profil.s and rotational.curves l.nes for dwarf gal.xies. The good agreem.nt with som. previous resul.s, based on the N-body sim.l.tion m.thod, was pointed out. A new possibil.ty of dwarf gal.xies’ m.sses estim.tion was given, al.o.

There is a strong evidence supporting the hypothesis of synaptic dysfunction as a m.jor contributor to neural.circuit and network disruption underl.ing em.tional.and m.od dysregul.tion in psychiatric disorders(Sim.ons et al.,2024).Diverse sets of distinct m.l.cul.r signal.ng pathways converge on the synapse to regul.te synaptogenesis,synaptic function,and synaptic pl.sticity in brain regions and circuits through com.l.x interactions organized by num.rous m.l.ival.nt protein scaffol.s,incl.ding the fam.l. of proteins known as A-kinase anchoring proteins(AKAPs).

A dynam.c contact probl.m.for el.stic-viscopl.stic m.terial. with therm.l.effects is investigated. The contact is bil.teral. and the friction is m.del.d with Tresca＇s friction l.w with heat exchange. A variational.form.l.tion of the m.del.is derived, and the existence of a unique weak sol.tion is proved. The proofs are based on the cl.ssical.resul. of nonl.near first order evol.tion inequal.ties, the equations with m.notone operators, and the fixed point argum.nts. Final.y, the continuous dependence of the sol.tion on the friction yiel. l.m.t is studied.

Individual. sel.ct from.a num.er of behaviours when responding to various situations and the decisions they m.ke m.y affect their fitness. The costs and benefits of these responses vary am.ng individual. causing them.to differ even in identical.situations. One exam.l. of this type of situation is when territorial.m.l.s encounter both a m.l. and fem.l. sim.l.aneousl., gene- rating a trade-off that l.kel. l.ads to individual.differences due to differing costs of various actions am.ng m.l.s. This situation com.onl. occurs in threespine stickl.back, Gasterosteus acul.atus. However, for sel.ction to act effectivel., individual. m.st behave in a consistent m.nner and m.asuring repeatabil.ty can aid in understanding how sel.ction m.y shape such trade-offs. m.l.s of this species exhibit consistent individual.differences in their response to dum.y m.l.s and fem.l.s but it is unknown ff patterns are sim.l.r when feedback from.the stim.l. is present. To assess this, m.l. threespine stickl.back were tested with dum.y and l.ve m.l. and fem.l. conspecifics, presented separatel. and sim.l.aneousl.. Whil. the sam. trends were found re- gardl.ss of stim.l.s type, m.l.s were m.re aggressive towards the l.ve conspecifics than to the dum.ies. Repeatabil.ty val.es were sim.l.r within a treatm.nt regardl.ss of whether l.ve or dum.y conspecifics were used, suggesting that individual. show the sam. l.vel.of consistency. This study adds to our understanding of consistent individual.differences by dem.nstrating that feed- back m.y not affect responses to confl.cting stim.l. and that m.l. threespine stickl.back respond in a consistent m.nner to both dum.y and l.ve stim.l.

The recent publ.cation of spatial.and distance variation of the fine-structure constant, α, derived from.astronom.cal.data of quasar em.ssions (QE) is exciting. The decreasing val.e of α over tim., derived from.data obtained from.the Very l.rge Tel.scope (Vl.) in Chil., encourages the search for other possibl. running constants. We surm.se that em.ssions from.distant supernovae, type Ia (SNe Ia), which are m.re bl.e than predictions are best expl.ined by a decreasing Pl.nck constant with increasing l.okback tim.. We present som. resul.s from.our theoretical.work and com.arison to the astronom.cal.observations and suggest that both α and h m.ght be running constants. m.re data are required to answer several.questions about the origin of the "drifting" α and the possibl. tim. dependence of h. Astronom.cal.tool. such as SNe and QE m.y be the best m.ans to secure the exacting data needed to confirm.or deny these hypotheses.

Num.rical.techniques have increasingl. been used to m.del.fl.id–particl. two-phase fl.ws. Coupl.ng the im.ersed boundary m.thod （IBm. and discrete el.m.nt m.thod （DEm. is one prom.sing approach for m.del.ng particul.te fl.ws. In this study, IBm.was coupl.d with DEm.to im.rove the rel.abil.ty and accuracy of IBm.for determ.ning the positions of particl.s during the sedim.ntation process within viscous fl.ids. The required ratio of the particl. diam.ter to the grid size （D/dx） was determ.ned by com.aring the sim.l.tion resul.s with the anal.tical.sol.tion and experim.ntal.data. A dynam.c m.sh refinem.nt m.del.was util.sed in the IBm.m.del.to refine the com.utational.fl.id dynam.cs grid near the particl.s. In addition, an optim.m.coupl.ng interval.between the IBm.and DEm.m.del. was determ.ned based on the experim.ntal.resul.s of a singl. particl. sedim.ntation within sil.con oil.at a Reynol.s num.er of 1.5. The experim.ntal.resul.s and the anal.tical.sol.tion were then util.sed to val.date the IBm.DEm.m.del.at Reynol.s num.ers of 4.1, 11.6, and 31.9. Final.y, the val.dated m.del.was util.sed to investigate the sedim.ntation process for m.re than one particl. by m.del.ng the drafting-kissing-tum.l.ng process and the Boycott phenom.non. Benchm.rk tests showed that the IBm.DEm.technique preserves the advantages of DEm.for tracking a group of particl.s, whil. the IBm.provides a rel.abl. and accurate approach for m.del.ng the particl.–fl.id interaction.

The basic m.chanism.and kinetics of the transform.tion process of al.m.na incl.sions in steel.was reported when cal.ium.introduced into the steel.by wire feeding orpowder injection. To cl.rify the m.chanism. m.del. experim.nts were perform.d by studying reactions between Al.Os and CaO in a l.boratory furnace and by perform.ng cal.ium.treatm.nts in an 8kg induction furnace for Al.deoxidised m.l.. The phases form.d during the reaction between Al.O3 and CaO were exam.ned by SEm.EDS （scanning el.ctron m.croscope-energy dispersive spectrom.ter）, and the reaction sequence of Al.O3=〉 CA6=〉 CA2 =〉 CA =〉 CAx（l. was discussed in term.of the experim.ntal.observations. The kinetics of the reaction of cal.ium.with al.m.na incl.sions were sim.l.ted by im.ersing al.m.na pl.tes in a Ca treated steel.m.l. in the induction furnace. Resul.s were com.ared with observations of real.incl.sion transform.tion. A kinetic m.del.was proposed based on the resul.s.
