Unification of the first law of quantum thermodynamics
Authors: Dann Roie , Kosloff Ronnie 
Published: March 2023

Abstract
Underlying the classical thermodynamic principles are analogous microscopic laws, arising from the fundamental axioms of quantum mechanics. These define quantum thermodynamic variables such as quantum work and heat and characterize the possible transformations of open quantum systems. The foremost quantum thermodynamic law is a simple statement concerning the conservation of energy. Nevertheless, there exist ambiguity and disagreement regarding the precise partition of a quantum system’s energy change to work and heat. By treating quantum mechanics as a comprehensive theory, applicable to both the micro and macroscopic domains, and employing dynamical symmetries, we bridge the gaps between five popular thermodynamic approaches to the first law. These include both autonomous and semi-classical formulations, which define work in terms of an ensemble average, as well as the single shot paradigm, where work is defined as a deterministic quantity.
Controllable sidebands of resonance fluorescence of a two-level system driven by bichromatic field
Authors: Yan Yiying , Lü Zhiguo , Luo JunYan , Zheng Hang 
Published: March 2023

Abstract
Strong polychromatic driving reshapes characteristics of the resonance fluorescence spectrum of a two-level system. Employing bichromatic driving feild with a low beat-frequency smaller than the emission rate of the system we demonstrate the exotic features of the fluorescence spectrum calculated by the numerical Floquet-Liouville approach and analytical method. It is found that fluorescence spectrum possesses two broadened sidebands in the place of the Rabi sidebands under certain conditions. Moreover, the heights and widths of the sidebands can be controlled by tuning the driving parameters. The properties of the spectrum is determined by the transitions between the Floquet states in a rotating frame. The broadened sidebands result from the quasi-continuous quasienergy spectrum which happens with steering the beat frequency lower. The present study provides insights into the Floquet engineering of the fluorescence spectral features with polychromatic excitation fields.
MeV dark matter with MeV dark photons in Abelian kinetic mixing theories
Authors: Compagnin Federico , Profumo Stefano , Fornengo Nicolao 
Published: March 2023

Abstract
We consider the cosmology and phenomenology of a dark photon portal to a simple dark
sector consisting of a single, light, fermionic dark matter particle species with mass in the
MeV range. We entertain three possible kinetic mixing structures of a new Abelian gauge
group U(1)dark with the visible sector through U(1)e.m., U(1)Y and T[SU(2)_L]. We assume the
dark photon to be massive and around the MeV scale, thus close to the mass scale of the
dark matter candidate. We compute the dark matter relic density via freeze-out and freeze-in,
entertaining the additional possibility of
a late inflationary period that could dilute the
dark matter yield of heavy candidates, and (ii) additional production modes, for models with under-abundant thermal production.
We explore the parameter space compatible with a variety
of experimental and astrophysical bounds, and discuss prospects for discovery with new CMB
probes and MeV gamma-ray telescopes.
Hadron spectra and pion form factor in dynamical holographic QCD model with anomalous 5D mass of scalar field*
Authors: Chen Ruixiang , Li Danning , Bitaghsir Fadafan Kazem , Huang Mei 
Published: March 2023

Abstract
The simplest version of the dynamical holographic QCD model is described by adding the KKSS model action on a dilaton-graviton coupled background, in which the AdS

metric is deformed by the gluon condensation and further deformed by the chiral condensation. In this framework, both the chiral symmetry breaking and linear confinement can be realized. The light-flavor hadron spectra and the pion form factor were investigated, but it was difficult to reconcile the light-flavor hadron spectra and pion form factor. By considering the anomalous 5-dimension mass correction of the scalar field from QCD running coupling, it is found that the light flavor hadron spectra and pion form factor can be described well simultaneously. In particular, the ground state and lower excitation states of the scalar, pseudo scalar, and axial vector meson spectra are improved. However, the vector meson spectra are not sensitive to the anomalous 5-dimension mass correction of the scalar field.

Abstract
The range of the U bosonic coupling constants in neutron star matter is a very interesting but still unsolved problem which has multifaceted influences in nuclear physics, particle physics, astrophysics and cosmology. The combination of the theoretical numerical simulation and the recent observations provides a very good opportunity to solve this problem. In the present work, the range of the U bosonic coupling constants is inferred based on the three relations of the mass–radius, mass-frequency and mass-tidal deformability in neutron stars containing hyperons using the GM1, TM1 and NL3 parameter sets under the two flavor symmetries of SU(6) and SU(3) in the framework of the relativistic mean field theory. Combined with observations from PSRs J1614-2230, J0348+0432, J2215-5135, J0952-0607, J0740+6620, J0030-0451, J1748-2446ad, XTE J1739-285, GW170817 and GW190814 events, our numerical results show that the U bosonic coupling constants may tend to be within the range from 0 to 20 GeV−2 in neutron star containing hyperons. Moreover, the numerical results of the three relations obtained by the SU(3) symmetry are better in accordance with observation data than those obtained by the SU(6) symmetry. The results will help us to improve the strict constraints of the equation of state for neutron stars containing hyperons.
Assessment of the impact of renewable energy on the balanced development and preservation of the carbon cycle in the regions of the Far Eastern Federal District of Russia
Authors: Dvinin D Y , Davankov A Y , Plaksina A L 
Published: March 2023

Abstract
The study took into account that renewable energy does not change the biospheric material and energy flows, which ensures the achievement of a general balance. To assess it, a special indicator of balance was used, which characterizes the ratio in energy indicators between industrial activity in the region and the state of its ecosystems. In addition, the need of carbon cycle preservation, which may be disturbed due to the peculiarities of the ecosystems of the regions, was taken into account. It was set that due to the existence of large areas of forest and swamp ecosystems, in all Far Eastern Federal District regions, ecosystems are effective absorbers of carbon dioxide. The total absorption of carbon dioxide in the district is 810.98 million tons. In nine regions of the District, industrial activity and ecosystems are in a balanced state in terms of energy indicators: in the Amur and Magadan Oblast, Khabarovsk, Kamchatka and Zabaykalsky Krai, the Republic of Buryatia and Sakha Republic (Yakutia), Chukotka Autonomous Okrug. The balance indicator in Primorsky Krai and the Sakhalin Oblast is greater than one, which indicates a violation of the balance. To achieve it in these regions, it will be necessary to increase the share of renewable energy in regional energy balances to 50% and 21%, respectively.

Published: March 2023

Abstract
The paper contains the studies of the influence of diatomite (high-silica rock) in its pure form and diatomite-based organic-mineral fertilizer and chicken manure on the barley yield. It was found that these fertilizers contributed to an increase in the barley grain yield by 0.12 and 0.26 t/ha (depending on the dose) when using diatomite and by 0.5 and 0.73 t/ha – organic-mineral fertilizer. The organic-mineral fertilizer based on diatomite and chicken manure was superior in effectiveness to the mineral one (N40P40K40).

Published: March 2023

Abstract
Global food security is threatened by extreme climate events, deterioration of the ecological and geopolitical situation, a difficult geopolitical situation, and disruption of supply chains. Therefore, issues related to increasing the productivity of agricultural crops, restoring disturbed lands, and increasing soil fertility come to the fore. The results of the work on the determination of physicochemical properties and biological activity for liquid humic-containing organic and organomineral fertilizers, which are produced on an industrial scale, are presented. Experiments were also carried out to evaluate the effectiveness of their application. For the study, samples of liquid organic and organomineral fertilizers containing humic substances and intended for use on private farms were selected. The following samples were tested: determination of the yield of free humic acids, determination of the ash content of humic acids, determination of the alkali content, determination of solubility in water, determination of biological activity. All samples allow you to get the effect of a biological plant growth stimulator. This indicates the great potential of humic substances in the composition of organic and organomineral fertilizers when used in agriculture in order to increase productivity. The highest performance in the totality of all the studied indicators has a sample that was obtained during the processing of brown coal.
Method for the calculation of total dipole moment for organic mass of brown and hard coals
Authors: Moskalenko T V , Mikheev V A , Vorsina E V 
Published: March 2023

Abstract
The article considers the study of the patterns of changes in the properties of coals in the metamorphism series and the identification of structural and chemical parameters that allow not only to correctly describe them, but also to use them as an express method of assessment. It is known that physical processes such as adhesion and cohesion play an important role in the processes of coal processing, since the adhesion of dissimilar or homogeneous particles brought into contact is due to intermolecular interaction. Determination of adhesive and cohesive properties of various substances, including solid fossil fuels, is not standardized in hardware. The total dipole moment is one of the indicators characterizing the intermolecular interaction. A method for calculating the total dipole moment based on an additive approach is presented. The calculated values of the total dipole moment of the organic mass of solid fossil fuels in the series “brown coal - hard coal - anthracite” showed a high correlation with the reflectance of vitrinite. As a result of mathematical data processing, equations were obtained for calculating the total dipole moment for brown and hard coals. The application of the equations obtained based on statistical processing of a large database and the calculation according to the proposed method can be used in calculating the parameters of such coal processing processes as briquetting, extraction, flotation, etc.

Abstract
At the Scientific Center of Vegetable, Melon and Industrial Crops (MoE RA) for 3 years (2020-2022), the use of Aquasource hydrogel (Ecotechnology LLC) in the cultivation of melon Cucumis melo L was investigated. Hydrogel in the ratio: Soil mix +Aaquasource (3:0.1), Soil mix+Aquasource (3:0.15), Soil mix +Aquasource (3:0.2) compared with the control (Soil mix without Aquasource) had a positive effect on the early appearance of female flowers, reducing the terms of technical ripening and fruit quality. The indicator of marketable yield of melon also exceeded the control (230.9±2.73 c/ha) and amounted to 287.5±2.94, 308.0±2.27 and 307.0±3.05 c/ha, respectively. A similar pattern was observed with seed yield: 360.7±2.87, 399.6±10.01, 392.1±9.20kg/ha, respectively, with control 287.2±8.05 kg/ha. An assessment of the economic efficiency of using Aquasource showed that by reducing the cost of water supply, labor force and provision of higher yield, the percentage of economic efficiency was 120.4-128.6%, and profitability - 67.6-69.0% (with control of 61.9%).

Published: March 2023

Abstract
The condition of the underground and surface hydrosphere as one of the shells of the human habitat plays an exceptional role in ensuring the normal functioning of the population. In Russian regions with developed industry and transport infrastructure, the hydrosphere is experiencing significant man-made loads, which are objectively characterized by saturation of its facilities with various industrial and household effluents containing harmful and toxic substances, including heavy metals and their compounds. The article presents the results of the development of a hydraulic network management system in these territories. Scientifically grounded approaches to the formation of an appropriate methodology for the construction of control subsystems are presented. In particular, the complex of integrated system analysis and synthesis was chosen as the basic analytical tools, which allows taking into account the fundamental properties of natural and technical systems. It is shown that effective control of the hydrosphere can be carried out only with the joint synchronous functioning of the control and regulating blocks. The regional system, built according to the proposed scheme, allows you to quickly develop and implement organizational and technical measures to normalize the chemical and biological composition of drainage waters.
Is everything quantum ‘spooky and weird’? An exploration of popular communication about quantum science and technology in TEDx talks
Authors: Meinsma Aletta Lucia , Kristensen Sanne Willemijn , Reijnierse W Gudrun , Smeets Ionica , Cramer Julia 
Published: March 2023

Abstract
Previous studies have identified four potential issues related to the popularisation of quantum science and technology. These include framing quantum science and technology as spooky and enigmatic, a lack of explaining underlying quantum concepts of quantum 2.0 technology, framing quantum technology narrowly in terms of public good and having a strong focus on quantum computing. Before assessing the effect of these potential issues on public perceptions, it is important to first determine whether these issues are actually present in popular communication. To this end, we conducted a content analysis in which we investigated how quantum science and technology are framed in a corpus of 501 TEDx talks. We also examined to what extent quantum experts, such as quantum scientists and leaders at organisations in quantum science and technology, communicate about quantum science and technology differently from non-experts, such as scientists from other disciplines and artists. Results showed that: (1) about a quarter of the talks framed quantum science and technology as spooky/enigmatic; (2) about half of the talks explained at least one underlying quantum concept (superposition, entanglement or contextuality) of quantum 2.0 technology; (3) quantum technology is narrowly framed in terms of public good as we found six times more talks mentioning benefits than risks; and (4) the main focus is on quantum computing at the expense of other quantum technologies. In addition, experts and non-experts differ on three out of four issues (only the fourth issue is similar for both). Our findings thus show that these potential issues related to the popularisation of quantum science and technology are present but not predominant in TEDx talks. Further research should explore their effect on public perceptions of quantum science and technology.
Becoming Elizabeth
Authors: Robb Megan Eaton 
Published: March 2023

Abstract
In the late eighteenth century, a Mughal woman named Sharaf un-Nisa lived with and bore children by the first Company Supervisor of Purnea. She followed him to Britain, changed her name to Elizabeth, and converted to Christianity. Cohabitations between native women and British East India Company servants were common. While scholars have attempted to compensate for the notorious dearth of information about these native women’s lives by reading East India Company archives, material evidence of this woman’s life lends insight to the embodied process of Anglicization. This article supplements existing research on native consorts with consideration of a family archive to consider the subjectivity of Elizabeth Sharaf un-Nisa as a process of transformation characterized by hybridity. This argument proceeds by a textual material analysis of a diverse range of materials from a family archive, including eighteenth and early nineteenth century private correspondence in English and Persian, as well as material analysis of paintings, jewelry, textiles, and a penmanship book.
Production of electrical energy from living plants in microbial fuel cells
Authors: Martinez Raymond Daniel Rodriguez , Bermudez Maria Eugenia Alvarez 
Published: March 2023

AbstractGrowing energy demand is a current problem with greater incidence in the future. The research objective is to establish seed bases to give a leading role to plants used in anthropogenic production activities and consumption, and even plants belonging to wildlife in terms of energy production. The use of living plants to obtain electrical energy through a microbial-vegetable fuel cell is proposed as a mechanism to supply the energy demand with easy access worldwide, especially in areas far from urban centres. In this work, the voltage produced by microbial-vegetable fuel cells was measured using graphite electrodes and plants belonging to the species of aloe (Aloe vera), corn (Zea mays), black beans (Phaseolus vulgaris), tomato (Solanum lycopersicum) and moss (Dicranidae). They were selected for their presence in everyday life and their great commercial and agricultural value, reaching a maximum voltage of 884 mV from moss. There is evidence that all plants can be a source of energy to a greater or lesser extent and that their performance is given by the plant root interactions at the electrodes. However, an extensive root system can favour the accumulation of substrate after the hydrolysis of dead roots, provided that their presence does not interfere with microbial activity on the anodic surface. For this, using plants with low resistance to thermal stress can lead to a substrate richer in substances that can be decomposed. Therefore, it is recommended to use plants according to their life cycle and the morphology of their roots, and plants that can grow in waterlogged conditions or without direct contact with the Sun.
Your Outpatient has Coronavirus Disease 2019: What Are the Treatment Options in the Current Severe Acute Respiratory Syndrome Coronavirus 2 Variant Climate?

Published: March 2023

Abstract
Mutations accumulated by novel Severe Acute Respiratory Syndrome Coronavirus 2 Omicron sublineages contribute to evasion of previously effective monoclonal antibodies for treatment or prevention of Coronavirus Disease 2019 (COVID-19). Other authorized or approved antiviral drugs such as nirmatrelvir/ritonavir, remdesivir, and molnupiravir are, however, predicted to maintain activity against these sublineages and are key tools to reduce severe COVID-19 outcomes in vulnerable populations. A stepwise approach may be taken to target the appropriate antiviral drug to the appropriate patient, beginning with identifying whether a patient is at high risk for hospitalization or other complications of COVID-19. Among higher risk individuals, patient profile (including factors such as age, organ function, and comedications) and antiviral drug access inform suitable antiviral drug selection. When applied in targeted fashion, these therapies serve as a complement to vital ongoing nonpharmaceutical interventions and vaccination strategies that reduce morbidity and maximize protection against COVID-19.
