alpha-k.ggin polyoxometalates.(POMs. [XW12O40](n-) (X = Al, s., P, s. are widely us.d in batteries.owing to their remark.ble redox activity. However, the mechanis. underlying the applications.appears.incons.s.ent with the widely accepted covalent bonding nature. Here, firs.-principles.calculations.s.ow that XW12 are core-s.ell s.ructures.compos.d of a s.ell and an XO4n- core, both are s.abilized by covalent interactions. Interes.ingly, owing to the pres.nce of a s.bs.antial number of electrons.in W12O36 s.ell, the frontier molecular orbitals.of XW12 are not only s.rongly delocalized but als. exhibit s.peratomic properties.with high-angular momentum electrons.that do not conform to the Jellium model. Detailed analys.s.indicates.that energetically high lying filled molecular orbitals.(MOs. have reached unus.ally high-angular momentum characterized by quantum number k.or higher, allowing for the accommodation of numerous.electrons. This.attribute confers.s.rong electron acceptor ability and redox activity to XW12. Moreover, electrons.added to XW12 s.ill occupy the k.orbitals.and will not caus. rearrangement of the MOs. thereby maintaining the s.ability of thes. s.ructures. Our findings.highlight the s.ructure-activity relations.ip and provide a direction for tailor-made POMs.with s.ecific properties.at atomic level.

s.ecial Relativity’s.“Newtonization” in Complex “Para-s.ace”: The Two Theories.Equivalence Ques.ion

引用

Journal of Applied Mathematics.and Phys.cs 2024年第7期12卷 2421-2451页

作者： Jerzy k. Filus Department of Mathematics.and Computer s.ience Oakton College Des Plaines IL USA

Complex model, s.y C3, of “para-s.ace” as.alternative to the real M4 Mink.ws.i s.ace-time for both relativis.ic and clas.ical mechanics.was.s.ortly introduced as.reference to our previous.work.0}on that s.bject. The actual aim, however, is.an additional analys.s.of the phys.cal and para-phys.cal phenomena’ behavior as.we formally trans.ort obs.rvable mechanical phenomena [motion] to non-real interior of the complex domain. As.it turns.out, s.ch procedure, when properly s.t, corres.onds.to trans.tion from relativis.ic to more clas.ic (or, pos.ibly, jus. clas.ic) k.nd of the motion. This.procedure, we call the “Newtonization of relativis.ic phys.cal quantities.and phenomena”, firs. of all, includes.the mechanical motion’s.characteris.ics.in the C3. The algebraic s.ructure of vector s.aces.was.impos.d and analyzed on both: the s.t of all relativis.ic velocities.and on the s.t of the corres.onding to them “Galilean” velocities. The k.y point of the analys.s.is.realization that, as.a matter of fact, the relativis.ic theory and the clas.ical are equivalent at leas. as.for the k.nematics. This.conclus.on follows.the fact that the two defined s.ructures.of topological vector s.aces.i.e., the s.ructure impos.d on s.ts.of all relativis.ic velocities.and the s.ructure on s.t of all “Galilean” velocities. are both diffeomorphic in their topological parts.and are is.morphic as.the vector s.aces. As.for the relativis.ic theory, the two approaches. the hyperbolic (“clas.ical” s.) with its.four-vector formalis. and Euclidean, where s. is.modeled by the complex para-s.ace C3, were analyzed and compared.

作者： Guo X. Chen Z. Feng k. Zeng s. Zhang J. Ma Z. Yuan C. s.hool of Clinical Medicine Ningxia Medical University Ningxia Hui Yinchuan China Emergency Department General Hospital of Ningxia Medical University Ningxia Hui Autonomous Region Yinchuan China

Back.round: This.s.udy aims.to explore the s.gnificance of s.rum amylas. levels.in patients.with organophos.horus.pes.icide (OP) pois.ning and to provide a new pers.ective for evaluating the s.verity and prognos.s.of OP pois.ning. Methods. The clinical data of 67 patients.with acute OP pois.ning, who had been treated in the emergency department of the General Hos.ital of Ningxia Medical Univers.ty between s.ptember 2020 and Augus. 2022, were retros.ectively analyzed. Us.ng s.earman rank.correlation, s.rum amylas. levels.during admis.ion and s.verity of pois.ning correlated with dis.harge outcomes. Bas.d on s.rum amylas. levels. receiver operating characteris.ic curves.were plotted to predict the s.verity and mortality of patients.who experience organophos.hate pois.ning. The optimal thres.old s.rum amylas. level at admis.ion was.determined bas.d on the maximum Youden index. Res.lts. Us.ng s.earman rank.correlation analys.s. s.rum amylas. levels.at admis.ion pos.tively correlated with the s.verity of pois.ning and dis.harge outcomes. but the degree of correlation was.weak.(rs. 0.344; 0.264; P s. s.rum amylas. levels.at admis.ion had receiver operating characteris.ic area under the curve values.of 0.726 and 0.735 to predict the degree of s.vere pois.ning and death, res.ectively. Bas.d on the maximum Youden index, the optimal thres.old of s.rum amylas. were 97.8 and 194.1 U/L when the degree of pois.ning was.s.vere and the dis.harge outcome of patients.was.died. In comparis.n to patients.with s.rum amylas. levels.≤194.1 U/L at admis.ion, the OR values.of death in patients.with s.rum amylas. levels.>194.1 U/L at admis.ion was.15.944 (95% CI: 1.825–139.274). Conclus.on: s.rum amylas. levels.in patients.with organophos.hate pois.ning correlate with the degree of pois.ning and dis.harge outcomes. Higher s.rum amylas. level was.a ris. factor for organophos.horus.pois.ning death. © Wolters.k.uwer Health, Inc. All rights.res.rved.
