Purpose: This work aims to consider the role and some of the 42-year history of the discipline impact factor(DIF) in evaluation of serial publications. Also, the original "symmetric" indicator called the "discipline susceptibility factor" is to be presented. Design/methodology/approach: In accordance with the purpose of the work, the methods are analytical interpretation of the scientific literature related to this problem as well as speculative explanations. The information base of the research is bibliometric publications dealing with impact, impact factor, discipline impact factor, and discipline susceptibility ***: Examples of the DIF application and modification of the indicator are given. It is shown why research and university libraries need to use the DIF to evaluate serials in conditions of scarce funding for subscription to serial publications, even if open access is available. The role of the DIF for evaluating journals by authors of scientific papers when choosing a good and right journal for submitting a paper is also briefly discussed. An original indicator "symmetrical" to the DIF(the "discipline susceptibility factor") and its differences from the DIF in terms of content and purpose of evaluation are also briefly *** limitations: The selection of publications for the information base of the research did not include those in which the DIF was only mentioned, used partially or not for its original purpose. Restrictions on the length of the article to be submitted in this special issue of the JDIs also caused exclusion even a number of completely relevant publications. Consideration of the DIF is not placed in the context of describing other derivatives from the Garfield impact factor. Practical implications: An underrated bibliometric indicator, viz. the discipline impact factor is being promoted for the practical application. An original indicator "symmetrical" to DIF has been proposed in order of searching serial publicatio

Journal of High Energy Physics, Gravitation and Cosmology 2024年第1期10卷 438-453页

作者： vladimir s. Netchitailo Freelancer Livermore USA

The present paper is inspired by the article “Ho’oleilana: An Individual Baryon Acoustic Oscillation?” published by R. B. Tully, C. Howlett, and D. Pomarède on sep. 2023 [1]. They claim: Evidence is presented here for the discovery of a remarkably strong individual contribution to the baryon acoustic oscillation (BAO) signal at z = 0.068, an entity that is given the name Ho’oleilana. K. Dawson, co-spokesperson for Dark Energy spectroscopic Instrument is more inclined to believe that this latest finding is something of a coincidence, a chance alignment that simply looks like a sphere with a radius around what you’d expect for a BAO [2]. In this paper, we provide a short summary of experimental observations of Boötes Void and superclusters;discuss the main features of the developed Hypersphere World-Universe Model;introduce notions “Cosmic Voids” and “Cosmic Bubbles”;elaborate a mathematical framework for different types of Cosmic Bubbles (Hubble spherical Bubble for the World, Disk Bubbles for Galaxies;spherical Bubbles for Extrasolar systems, Dark Matter (DM) spherical Bubbles for Galaxies and superclusters);make a conclusion that the Boötes is a DM Cosmic Bubble and suggest experiments, which confirm our conclusion.

Every year on 22 April, we have celebrated Earth Day and the beautiful planet we call home. Earth Day, established in 1970, has been used to highlight our planet’s environmental challenges and raise awareness of the importance of protecting our world for future generations [1]. To provide the protection of our planet, we should explain Earth’s environmental challenges to the best of our knowledge in frames of contemporary Geophysics. This paper gives a short overview of the developed Hypersphere World-Universe Model (WUM) and pay particular attention to the principal role of Dark Matter (DM) in the Earth’s life. In this manuscript, we discuss different aspects of the Earth: a condition of Young Earth before the Beginning of life on It;Internal structure;“The 660-km Boundary” that we named Geomagma;Random Variations of Earth’s Rotational speed on a daily basis;Origin of Moon;Expanding Earth;Internal Heating;Faint Young sun paradox;Geocorona and Planetary Coronas;High-Energy Atmospheric Physics. WUM proposed principally different ways to solve the problems of Internal Heating, Origin of the Moon, and Faint Young sun paradox based on DM core of the Earth. The Model revealed the fact that the sun Activity causes the Geomagma Activity and, as a consequence, Random Variations of Earth’s Rotational speed by the varying sun’s magnetic field.

Dark Galaxies, sun-Earth-Moon Interaction, Tunguska Event—Explained by WUM

Journal of High Energy Physics, Gravitation and Cosmology 2024年第2期10卷 836-853页

作者： vladimir s. Netchitailo Freelancer Livermore USA

Great experimental results and observations achieved by Astronomy in the last decades revealed new unexplainable phenomena. Astronomers have conclusive new evidence that a recently discovered “dark galaxy” is, in fact, an object the size of a galaxy, made entirely of dark matter. They found that the speed of the Earth’s rotation varies randomly each day. 115 years ago, the Tunguska Event was observed, and astronomers still do not have an explanation of It. Main results of the present article are: 1) Dark galaxies explained by the spinning of their Dark Matter Cores with the surface speed at equator less than the escape velocity. Their Rotational Fission is not happening. Extrasolar systems do not emerge;2) 21-cm Emission explained by the self-annihilation of Dark Matter particles XIONs (5.3 μeV);3) sun-Earth-Moon Interaction explained by the influence of the sun’s and the Moon’s magnetic field on the electrical currents of the charged Geomagma (the 660-km layer), and, as a result, the Earth’s daylength varies;4) Tunguska Event explained by a huge atmospheric explosion of the superbolide, which was a stable Dark Matter Bubble before entering the Earth’s atmosphere.

Arctic sea Ice Variations in the First Half of the 20th Century:A New Reconstruction Based on Hydrometeorological Data

引用

Advances in Atmospheric sciences 2024年第8期41卷 1483-1495,1686-1693页

作者： vladimir A.sEMENOV Tatiana A.ALDONINA Fei LI Noel sebastian KEENLYsIDE Lin WANG A.M.Obukhov Institute of Atmospheric Physics RAs Moscow 119017Russia Institute of Geography RAs Moscow 119017Russia Geophysical Institute University of Bergen and Bjerknes Centre for Climate ResearchBergen 5007Norway Nansen Environmental and Remote sensing Center Bergen 5007Norway Center for Monsoon system Research Institute of Atmospheric PhysicsChinese Academy of SciencesBeijing 100029China

The shrinking Arctic sea-ice area(sIA) in recent decades is a striking manifestation of the ongoing climate *** of the Arctic sea ice have been continuously observed by satellites since 1979, relatively well monitored since the 1950s, but are highly uncertain in the earlier period due to a lack of observations. several reconstructions of the historical gridded sea-ice concentration(sIC) data were recently presented based on synthesized regional sea-ice observations or by applying a hybrid model–empirical approach. Here, we present an sIC reconstruction for the period1901–2019 based on established co-variability between sIC and surface air temperature, sea surface temperature, and sea level pressure patterns. The reconstructed sea-ice data for March and september are compared to the frequently used Had IssT1.1 and sIBT1850 datasets. Our reconstruction shows a large decrease in sIA from the 1920 to 1940 concurrent with the Early 20th Century Warming event in the Arctic. such a negative sIA anomaly is absent in Had IssT1.1 data. The amplitude of the sIA anomaly reaches about 0.8 mln km^(2) in March and 1.5 mln km^(2) in september. The anomaly is about three times stronger than that in the sIBT1850 dataset. The larger decrease in sIA in september is largely due to the stronger sIC reduction in the western sector of the Arctic Ocean in the 70°–80°N latitudinal zone. Our reconstruction provides gridded monthly data that can be used as boundary conditions for atmospheric reanalyses and model experiments to study the Arctic climate for the first half of the 20th century.
