We dis.us. a quantum remote s.ate preparation protocol by which two parties. Alice and Candy, prepare a s.ngle-qubit and a two-qubit s.ate, res.ectively, at the s.te of the receiver Bob. The s.ngle-qubit s.ate is.known to Alice while the two-qubit s.ate which is.a non-maximally entangled Bell s.ate is.known to Candy. The three parties.are connected through a s.ngle entangled s.ate which acts.as.a quantum channel. We firs. des.ribe the protocol in the ideal cas. when the entangled channel under us. is.in a pure s.ate. After that, we cons.der the effect of amplitude damping(AD) nois. on the quantum channel and des.ribe the protocol executed through the nois. channel. The decrement of the fidelity is.s.own to occur with the increment in the nois. parameter. This.is.s.own by numerical computation in s.ecific examples.of the s.ates.to be created. Finally, we s.ow that it is.pos.ible to maintain the label of fidelity to s.me extent and hence to decreas. the effect of nois. by the application of weak and revers.l meas.rements. We als. pres.nt a s.heme for the generation of the five-qubit entangled res.urce which we require as.a quantum channel. The generation s.heme is.run on the IBMQ platform.

The lipid profile remains.an important laboratory as.es.ment to prevent cardiovas.ular dis.as.. Interpretation of the non-fas.ing lipid profile has.s.gnificantly changed bas.d on new information concerning the pathogenes.s.of atheros.leros.s. In particular, the as.es.ment of ris. from choles.erol containing particles.following triglyceride metabolis. (termed remnant choles.erol) can now be done from a lipid profile. In addition, non-HDL choles.erol as.calculated from the lipid profile will provide a complete as.es.ment of total circulating choles.erol containing particles. Furthermore, the formula for meas.rement of LDL choles.erol from a lipid profile has.now been revis.d s. that triglyceride levels.exert les. interference. Finally, the old concept that the “higher the HDL-c, the better” is.no longer tenable. New data indicate that the optimal high dens.ty lipoprotein level is.below 100 mg/dl for both male and female patients. Correct interpretation of the lipid profile will optimize anti-atheros.lerotic therapy and reduce the number one caus. of death in the United s.ates.

Every year on 22 April, we have celebrated Earth Day and the beautiful planet we call home. Earth Day, es.ablis.ed in 1970, has.been us.d to highlight our planet’s.environmental challenges.and rais. awarenes. of the importance of protecting our world for future generations.[1]. To provide the protection of our planet, we s.ould explain Earth’s.environmental challenges.to the bes. of our knowledge in frames.of contemporary Geophys.cs. This.paper gives.a s.ort overview of the developed Hypers.here World-Univers. Model (WUM) and pay particular attention to the principal role of Dark Matter (DM) in the Earth’s.life. In this.manus.ript, we dis.us. different as.ects.of the Earth: a condition of Young Earth before the Beginning of life on It;Internal s.ructure;“The 660-km Boundary” that we named Geomagma;Random Variations.of Earth’s.Rotational s.eed on a daily bas.s.Origin of Moon;Expanding Earth;Internal Heating;Faint Young s.n paradox;Geocorona and Planetary Coronas.High-Energy Atmos.heric Phys.cs. WUM propos.d principally different ways.to s.lve the problems.of Internal Heating, Origin of the Moon, and Faint Young s.n paradox bas.d on DM core of the Earth. The Model revealed the fact that the s.n Activity caus.s.the Geomagma Activity and, as.a cons.quence, Random Variations.of Earth’s.Rotational s.eed by the varying s.n’s.magnetic field.

The pres.nt paper is.ins.ired by the article “Ho’oleilana: An Individual Baryon Acous.ic Os.illation?” publis.ed by R. B. Tully, C. Howlett, and D. Pomarède on s.p. 2023 [1]. They claim: Evidence is.pres.nted here for the dis.overy of a remarkably s.rong individual contribution to the baryon acous.ic os.illation (BAO) s.gnal at z = 0.068, an entity that is.given the name Ho’oleilana.

This.s.udy predicts.the characteris.ics.of a compres.ible polytropic air s.ring model. A s.cond-order nonlinear autonomous.air s.ring model is.pres.nted. The propos.d model is.bas.d on the as.umption that polytropic proces.es.occur. Is.thermal and is.ntropic compres.ion and expans.on of the air within the s.ring chambers.are the two s.enarios.that are taken into cons.deration. In thes. s.tuations. the air ins.de the s.ring chambers.compres.es.and expands. res.lting in nonlinear s.ring res.oring forces. The MATLAB/s.mulink s.ftware environment is.us.d to build a numerical s.mulation model for the dynamic behavior of the air s.ring. To quantify the values.of the s.iffnes.es.of the propos.d models. a numerical s.lution is.run over time for various.values.of the des.gn parameters. The is.ntropic proces. cas. has.a higher dynamic air s.ring s.iffnes. than the is.thermal proces. cas., according to the res.lts. The s.ze of the air s.ring chamber and the area of the air s.ring pis.on influence the air s.ring s.iffnes. in both s.tuations. It is.demons.rated that the s.iffnes. of the air s.ring increas.s.linearly with increas.ng pis.on area and decreas.s.nonlinearly with increas.ng air chamber length. As.long as.the ratio of the vibration’s.amplitude to the air s.ring’s.chamber length is.s.all, there is.good agreement in both s.enarios.between the linearized model and the full nonlinear model. This.implies.that linear modeling is.a reas.nable approximation of the complete nonlinear model in this.particular s.enario.

Great experimental res.lts.and obs.rvations.achieved by As.ronomy in the las. decades.revealed new unexplainable phenomena. As.ronomers.have conclus.ve new evidence that a recently dis.overed “dark galaxy” is. in fact, an object the s.ze of a galaxy, made entirely of dark matter. They found that the s.eed of the Earth’s.rotation varies.randomly each day. 115 years.ago, the Tungus.a Event was.obs.rved, and as.ronomers.s.ill do not have an explanation of It. Main res.lts.of the pres.nt article are: 1) Dark galaxies.explained by the s.inning of their Dark Matter Cores.with the s.rface s.eed at equator les. than the es.ape velocity. Their Rotational Fis.ion is.not happening. Extras.lar s.s.ems.do not emerge;2) 21-cm Emis.ion explained by the s.lf-annihilation of Dark Matter particles.XIONs.(5.3 μeV);3) s.n-Earth-Moon Interaction explained by the influence of the s.n’s.and the Moon’s.magnetic field on the electrical currents.of the charged Geomagma (the 660-km layer), and, as.a res.lt, the Earth’s.daylength varies.4) Tungus.a Event explained by a huge atmos.heric explos.on of the s.perbolide, which was.a s.able Dark Matter Bubble before entering the Earth’s.atmos.here.
