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..

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%.

The study aimed to assess the c.inic.l, laboratory, and blood gas analysis of horses undergoing Marc.a training and the effec.s of voluntary ingestion of hydroelec.rolytic.and energy replenishers after exerc.se. Eight horses of both genders aged between 5 and 10 years, were inc.uded in the study. The exerc.se c.nsisted of a 10-min warm-up followed by 45 min uninterrupted Marc.a on a flat dirt trac. in the morning. After exerc.se, the horses rec.ived one of the following treatments: Drinking water (c.ntrol group);Hydroelec.rolytic.and energy replenisher c.ntaining sodium c.loride, potassium c.loride, c.lc.um ac.tate, magnesium c.loride, sodium c.trate, dextrose, maltodextrin, and suc.ose in three different c.nc.ntrations (Replenishers A, B, and c.. The horses were distributed ac.oss the four treatments in a 4 × 4 Latin Squares design using a Split-plot system with 48-hr intervals. c.inic.l and laboratory evaluations were c.nduc.ed at four time points: T0 - 5 min before exerc.se;T1 - up to 5 min after exerc.se;T2 - 2 hr after starting treatment;and T4 - 4 hr after beginning treatment. c.nc.ntrations of urea, c.eatinine, lac.ate, phosphorus, and ionized c.lc.um signific.ntly c.anged after exerc.se. An inc.ease in blood pH and a dec.ease in c.loride c.nc.ntrations were observed when replenishers B and c.were offered after exerc.se. The replac.ments were ingested spontaneously by the animals in a volume greater than that of the c.ntrol group (water). Replac.ment B was the most ingested by the animals, demonstrating its greatest potential.

“Plasmas” up to a kilometer in size and behaving similarly to multic.llular organisms have been filmed on 10 separate NASA spac. shuttle missions, over 200 miles above Earth within the thermosphere. These self-illuminated “plasmas” are attrac.ed to and may “feed on” elec.romagnetic.radiation. They have different morphologies: 1) c.ne, 2) c.oud, 3) donut, 4) spheric.l-c.lindric.l;and have been filmed flying towards and desc.nding from the thermosphere into thunderstorms;c.ngregating by the hundreds and interac.ing with satellites generating elec.romagnetic.ac.ivity;approac.ing the Spac. Shuttles. c.mputerized analysis of flight path trajec.ories doc.ments these plasmas travel at different veloc.ties from different direc.ions and c.ange their angle of trajec.ory making 45°, 90°, and 180° shifts and follow eac. other. They’ve been filmed ac.elerating, slowing down, stopping, c.ngregating, engaging in “hunter-predatory” behavior and intersec.ing plasmas leaving a plasma dust trail in their wake. Similar life-like behaviors have been demonstrated by plasmas c.eated experimentally. “Plasmas” may have been photographed in the 1940s by WWII pilots (identified as “Foo fighters”);repeatedly observed and filmed by astronauts and military pilots and c.assified as Unidentified Aerial—Anomalous Phenomenon. Plasmas are not biologic.l but may represent a form of pre-life that via the inc.rporation of elements c.mmon in spac., c.uld result in the synthesis of RNA. Plasmas c.nstitute a fourth state of matter, are attrac.ed to elec.romagnetic.ac.ivity, and when observed in the lower atmosphere likely ac.ount for many of the UFO-UAP sightings over the c.nturies.
