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.

哈纳菲教授与赵汀阳教授围绕“天下”以及跨文化问题展开了一次对话。“天下”是一个面向全世界的概念,等待着属于它的可能未来。天下体系在其概念化设定中,旨在容纳一切造物,从而构成一种“无外”世界,实现所有文明的“协和”。在赵汀阳的论证中,“天下”是一种将敌意化为善意的方法论或艺术。与传统观念相比,为了使“天下”的重新构想更为合理和实用,赵汀阳提出了三个“宪法性”的原则:(1)世界的内部化;(2)关系理性;(3)孔子改善。在知识论的意义上,新的天下体系同时设想了与之匹配的新百科全书概念,它意味着知识摆脱了空间限制,并且能够依据平等的尊重和互惠的认识,从而容纳所有文明的所有知识。两位教授也对变在存在论、智慧民主、预付人权理论及价值修饰词等问题进行了讨论。

Dark Galaxies. s.n-Earth-Moon Interaction, Tungus.a Event—Explained by WUM

引用

Journal of High Energy Phys.cs. Gravitation and Cos.ology 2024年第2期10卷 836-853页

作者： Vladimir s. Netchitailo Freelancer Livermore USA

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.

Health care is.an important part of human life and is.a right for everyone. One of the mos. bas.c human rights.is.to receive health care whenever they need it. However, this.is.s.mply not an option for everyone due to the s.cial conditions.in which s.me communities.live and not everyone has.acces. to it. This.paper aims.to s.rve as.a reference point and guide for us.rs.who are interes.ed in monitoring their health, particularly their blood analys.s.to be aware of their health condition in an eas. way. This.s.udy introduces.an algorithmic approach for extracting and analyzing Complete Blood Count (CBC) parameters.from s.anned images. The algorithm employs.Optical Character Recognition (OCR) technology to proces. images.containing tabular data, s.ecifically targeting CBC parameter tables. Upon image proces.ing, the algorithm extracts.data and identifies.CBC parameters.and their corres.onding values. It evaluates.the s.atus.(High, Low, or Normal) of each parameter and s.bs.quently pres.nts.evaluations. and any potential diagnos.s. The primary objective is.to automate the extraction and evaluation of CBC parameters. aiding healthcare profes.ionals.in s.iftly as.es.ing blood analys.s.res.lts. The algorithmic framework aims.to s.reamline the interpretation of CBC tes.s. potentially improving efficiency and accuracy in clinical diagnos.ics.
