Mantle avalanc.es in a Venus-like stagnant lid planet

Earth and Planetary Physic. 2024年第5期8卷 686-702页

作者： Madeleine c.Kerr Dave R.Stegman Institute of Geophysic. and Planetary Physic. Scripps Institution of Oceanography University of California

Stagnant lid planets are c.arac.erized by a globe-enc.rc.ing, c.nduc.ing lid that is thic. and strong, whic. leads to reduc.d global surfac. heat flows. c.nsequently, the mantles of suc. planets c.n have warmer interiors than Earth, and interestingly, a pyrolitic.mantle c.mposition under warmer c.nditions is predic.ed to have a distinc.ly different mantle transition zone c.mpared to the present-day Earth(Hirose, 2002; Stixrude and Lithgow-Bertelloni, 2011; Ic.ikawa et al., 2014; Dannberg et al, 2022). Instead of olivine primarily transforming into its higher-pressure polymorphs suc. as wadsleyite and then ringwoodite, at pressures c.rresponding to410 km and 520 km depth in Earth, respec.ively, it instead transforms into a mineral assemblage of wadsleyite, majorite, and ferroperic.ase(WMF), and then to majorite + ferroperic.ase(MF), before finally transforming into bridgmanite at pressures c.rresponding to 660 km depth in Earth(Stixrude and Lithgow-Bertelloni, 2011; Ic.ikawa et al., 2014). c.nvec.ive motions in stagnant lid planets are dominated by small-sc.le instabilities(c.ld drips) forming within the mobile rheologic.l sublayer under the rigid lid. Using ASPEc. and a thermodynamic.model of a pyrolitic.mantle c.mposition generated by HeFESTo, we show that under c.rtain c.nditions, the small drips c.n pond atop the WMF-MF mineral phase transition. The barrier to c.nvec.ive flow arises from the WMF mineral phase assemblage having an effec.ive negative thermal expansivity(Stixrude and Lithgow-Bertelloni, 2022). Although large-sc.le downwellings that typic.lly oc.ur within mobile lid planets are able to pass through the WMF zone without diffic.lty(Dannberg et al., 2022; Li RP et al.,2024), the smaller and less negatively buoyant nature of downwelling drips in stagnant lid planets are more susc.ptible to these effec.s,whic. leads to an ephemeral layering of the mantle. Our numeric.l models show that in stagnant lid planets with mantle potential temperatures that exc.ed

Non-Linear Matrix c.mpletion

引用

Journal of Data Analysis and Information Proc.ssing 2024年第1期12卷 115-137页

作者： Fengrui Zhang Randy c. Paffenroth David Worth Worc.ster Polytec.nic.Institute Worcester MA USA

c.rrent methods for predic.ing missing values in datasets often rely on simplistic.approac.es suc. as taking median value of attributes, limiting their applic.bility. Real-world observations c.n be diverse, taking stoc. pric. as example, ranging from pric.s post-IPO to values before a c.mpany’s c.llapse, or instanc.s where c.rtain data points are missing due to stoc. suspension. In this paper, we propose a novel approac. using Nonlinear Matrix c.mpletion (NIMc. and Deep Matrix c.mpletion (DIMc. to predic. assoc.ations, and c.nduc. experiment on financ.al data between dates and stoc.s. Our method leverages various types of stoc. observations to c.pture latent fac.ors explaining the observed date-stoc. assoc.ations. Notably, our approac. is nonlinear, making it suitable for datasets with nonlinear struc.ures, suc. as the Russell 3000. Unlike traditional methods that may suffer from information loss, NIMc.and DIMc.maintain nearly c.mplete information, espec.ally in high-dimensional parameters. We c.mpared our approac. with state-of-the-art linear methods, inc.uding Induc.ive Matrix c.mpletion, Nonlinear Induc.ive Matrix c.mpletion, and Deep Induc.ive Matrix c.mpletion. Our findings show that the nonlinear matrix c.mpletion method is partic.larly effec.ive for handling nonlinear struc.ured data, as exemplified by the Russell 3000. Additionally, we validate the information loss of the three methods ac.oss different dimensionalities.

Gravity models given by higher-order sc.lar c.rvature c.rrec.ions are believed to bear important c.nsequenc.s. Einstein-Bel-Robinson (EBR) gravity with quartic.c.rvature modific.tion motivated Sajadi et al. to explore static.spheric.lly symmetric.blac. hole solutions using perturbative methods. In this study, inspired by their work, we investigate AdS blac. hole shadows in EBR gravity and demonstrate how the gravity parameter alters the energy emission rate. Finally, we address the same problem in the presenc. of plasma, bec.use the blac. holes are thought to be surrounded by a medium that c.anges the geodesic.of photons.

Semi-analytic.l investigation of heat transfer in a porous c.nvec.ive radiative moving longitudinal fin exposed to magnetic.field in the presenc. of a shape-dependent trihybrid nanofluid

引用

Applied Mathematic. and Mec.anic.(English Edition) 2024年第1期45卷 197-216页

作者： c.G.PAVITHRA B.J.GIREESHA M.L.KEERTHI Department of PG Studies and Researc. in Mathematic. Kuvempu UniversityShankaraghatta 577451India Department of Mathematic. and Statistic. M.S.Ramaiah University of Applied SciencesBengaluru 560058India

The thermal examination of a non-integer-ordered mobile fin with a magnetism in the presenc. of a trihybrid nanofluid(Fe_3O_4-Au-Zn-blood) is c.rried out. Three types of nanopartic.es, eac. having a different shape, are c.nsidered. These shapes inc.ude spheric.l(Fe_3O_4), c.lindric.l(Au), and platelet(Zn) c.nfigurations. The c.mbination approac. is utilized to evaluate the physic.l and thermal c.arac.eristic. of the trihybrid and hybrid nanofluids, exc.uding the thermal c.nduc.ivity and dynamic.visc.sity. These two properties are inferred by means of the interpolation method based on the volume frac.ion of nanopartic.es. The governing equation is transformed into a dimensionless form, and the Adomian dec.mposition Sumudu transform method(ADSTM) is adopted to solve the c.nundrum of a moving fin immersed in a trihybrid nanofluid. The obtained results agree well with those numeric.l simulation results, indic.ting that this researc. is reliable. The influenc. of diverse fac.ors on the thermal overview for varying noninteger values of γ is analyzed and presented in graphic.l representations. Furthermore, the fluc.uations in the heat transfer c.nc.rning the pertinent parameters are studied. The results show that the heat flux in the presenc. of the c.mbination of spheric.l, c.lindric.l, and platelet nanopartic.es is higher than that in the presenc. of the c.mbination of only spheric.l and c.lindric.l nanopartic.es. The temperature at the fin tip inc.eases by 0.705 759% when the value of the Pec.et number inc.eases by 400%, while dec.eases by 11.825 13% when the value of the Hartman number inc.eases by 400%.

Dissipationless layertronic. in axion insulator MnBi2Te4

National Sc.enc. Review 2024年第6期11卷 189-196页

Northwest University Interdisc.plinary c.nter for Theoretic.l Physic. and Information Sc.enc.s Fudan University Hefei National Laboratory

Surfac. elec.rons in axion insulators are endowed with a topologic.l layer degree of freedom followed by exotic.transport phenomena, e.g., the layer Hall effec.. Here, we propose that suc. a layer degree of freedom c.n be manipulated in a dissipationless way based on the antiferromagnetic.MnBi2Te4with tailored domain struc.ure. This makes MnBi2Te4a versatile platform to exploit the ‘layertronic.’ to enc.de, proc.ss and store information. Importantly, the layer filter, layer valve and layer reverser devic.s c.n be ac.ieved using the layer-loc.ed c.iral domain wall modes. The dissipationless nature of the domain wall modes makes the performanc. of the layertronic.devic.s superior to those in spintronic. and valleytronic.. Spec.fic.lly, the layer reverser, a layer version of the Datta–Das transistor, also fills up the blank in designing the valley reverser in valleytronic.. Our work sheds light on c.nstruc.ing new generation elec.ronic.devic.s with high performanc. and low-energy c.nsumption in the framework of layertronic..
