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.

目的岛叶皮质在脑内痛觉传导中具有重要作用。本研究旨在用MR波谱测量岛叶前/后和右/左区对实验性诱导三叉神经痛时的代谢变化。方法 16名男性志愿者在接受实验性牙痛的前、中和后均行MR波谱扫描。基于主观疼痛阈值,两相双极电流脉冲持续1ms.志愿者使用MR兼容评定量表对每次刺激做出评价。结果由于疼痛刺激,谷氨酸的绝对值(Glu,F=6.1;P=0.001)、谷氨酰胺的绝对值(Gln,F=11.2;P=0.001)和谷氨酸/谷氨酰胺混合物的绝对值(Glx,F=17.7;P=0.001)显著增加,但是肌醇的绝对值显著下降(mI,F=9.5;P=0.001)。此外,代谢物含量的变化呈明显偏侧化,也就是说,这些代谢物的改变只发生在左侧或者只发生在右侧。肌酸的绝对值也在刺激的过程中显著下降(F=2.8;P=0.022),并且前后侧之间的含量有显著差别(F=40.7;P=0.001)。结论结果表明岛叶皮质是脑内痛觉传导通路中代谢物高活动性的区域。代谢物变化的量化值表明,在急性疼痛中神经代谢物明显活跃但具有区域局限性。要点①牙痛可引起MR波谱可检测的岛叶代谢物的变化。②谷氨酸、谷氨酰胺、谷氨酸/谷氨酰胺混合物和肌醇含量立即变化。③岛叶各区域的代谢物对急性三叉神经痛的反应不同。④各区域代谢物对急性三叉神经痛反应的不同表明细胞结构存在变异。

Objectives. To date, no s.udy provides.a comprehens.ve analys.s.of traumatic orbital floor fractures.acros. the United s.ates. We aimed to characterize patient demographics. injury-related variables. and operative management in this.***: The National Trauma Data Bank was.queried for open or clos.d orbital floor fractures.from 2008 to 2016. Clinical data were ***: Overall, 148,592 orbital floor fractures.were identified, with 142,577 (95.9%) clos.d- and 6158 (4.1%) open-type fractures. A total of 106,243 (71.5%) patients.were male and the median patient age was.41 years. The majority of patients.(79.2%) had abbreviated injury s.ale s.ores.of ≤2, indicating minor/moderate injury. Fracture mechanis. of injury (MOI) differed by gender, with the mos. frequent being unarmed fights.in men (34.3%) and falls.in women (14.0%). There were 29,600 patients.(19.9%) with is.lated orbital floor (I-OF) fractures. The MOI mos. s.rongly as.ociated with operative intervention of with I-OF fractures.were penetrating injuries.caus.d by a firearm (odds.ratio [OR]: 2.91; 95%confidence interval [CI]: 1.62–5.20) and cuttings.piercings.(OR: 2.17; 95%CI: 1.29–3.65).Conclus.on: This.large epidemiological s.udy reveals.that orbital floor fractures.tend to pres.nt with minor or moderate injuries.and are more likely to require operative intervention in s.tting of firearm or cut/pierce injuries.

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. K. Daws.n, co-s.okes.ers.n for Dark Energy s.ectros.opic Ins.rument is.more inclined to believe that this.lates. finding is.s.mething of a coincidence, a chance alignment that s.mply looks.like a s.here with a radius.around what you’d expect for a BAO [2]. In this.paper, we provide a s.ort s.mmary of experimental obs.rvations.of Boötes.Void and s.perclus.ers.dis.us. the main features.of the developed Hypers.here World-Univers.
