FREE LONGITUDINAL VIBRATIONS OF THE ROD WITH CONCENTRATED MASS
Authors: Культербаев Х.П. 
Published: March 2023

Постановка задачи. Рассматриваются продольные колебания вертикального стального стержня постоянного сечения с сосредоточенной массой на конце. Это сооружение находится вблизи эпицентра землетрясений, где сейсмические волны имеют вертикальное направление, наиболее опасное для прочности стержня. При выводе уравнения продольных колебаний предполагается, что гипотеза плоских поперечных сечений справедлива. Статическая часть деформаций не учитывается ввиду малости. Математическая модель колебаний состоит из основного дифференциального уравнения и краевых условий. Для решения задачи используются методы разделения переменных и конечных разностей. Дифференциальное уравнение и краевые условия преобразуются в систему алгебраических уравнений, по которым определены первые собственные значения и формы колебаний.
Problem Statement. Longitudinal vibrations of a vertical steel rod of constant cross section with a concentrated mass at the end are considered. This structure is located near the epicenter of earthquakes, where seismic waves have a vertical direction, the most dangerous for the strength of the rod. When deriving the equation of longitudinal vibrations, it is assumed that the hypothesis of flat cross sections is valid. The static part of the deformations is not taken into account due to their smallness. The mathematical model of oscillations consists of the main differential equation and boundary conditions. To solve the problem, methods of separation of variables and finite differences are used. The differential equation and boundary conditions are transformed into a system of algebraic equations, which are used to determine the first eigenvalues and vibration modes.

The objective of this paper was to evaluate productivity, nutritional value of forage and tillering of elephant grass cv. BRS Kurumi under different pre-defoliation and post-defoliation canopy heights (residual height). The experimental design consisted in a randomized complete block design, with four replications. Treatments corresponded to the factorial combination of two pre‐defoliation heights (60 and 80 cm) and three post-defoliation residue heights (10, 25 and 40 cm), combined in factorial design 2 x 3, being, respectively, 60 x 10 cm; 60 x 25 cm; 60 x 40 cm; 80 x 10 cm; 80 x 25 cm; 80 x 40 cm. Productive, bromatological, carbohydrate fractionation and in situ degradability characteristics were evaluated. Results indicated that if the objective is to seek short intervals between grazing, associated with higher forage quality, the 60 x 25, 60 x 40 and 80 x 40 managements are the most indicated ones. For maximum forage productivity, 80 x 10 and 80 x 25 are the most recommended ones. For tillering, a canopy height management of 80 cm is preferred, with 80 x 25 for aerial tillers and 80 x 40 for basal tillers.

Formation of the First Planetesimals via the Streaming Instability in Globally Turbulent Protoplanetary Disks?
Authors: Estrada Paul R. , Umurhan Orkan M. 
Published: March 2023

Abstract
Using self-consistent models of turbulent particle growth in an evolving protoplanetary nebula of solar composition, we find that recently proposed local metallicity and Stokes number criteria necessary for the streaming instability to generate gravitationally bound particle overdensities are generally not approached anywhere in the disk during the first million years, an epoch in which meteoritic and observational evidence strongly suggests that the formation of the first planetesimals and perhaps giant planet core accretion are already occurring.

Abstract
We conduct hard X-ray to radio multiwavelength spectral energy distribution (SED) decomposition for 57 local luminous and ultraluminous infrared galaxies observed with the Nuclear Spectroscopic Telescope Array and/or Swift/Burst Alert Telescope in the GOALS sample. We modify the latest SED-fitting code X-CIGALE by implementing the infrared (IR) CLUMPY model, allowing us to conduct the multiwavelength study with the X-ray torus model XCLUMPY self-consistently. Adopting the torus parameters obtained by the X-ray fitting, we estimate the properties of the host galaxies, active galactic nucleus (AGN) tori, and polar dust. The star formation rates (SFRs) become larger with merger stage and most of them are above the main sequence. The SFRs are correlated with radio luminosity, indicating starburst emission is dominant in the radio band. Although polar-dust extinction is much smaller than torus extinction, the UV-to-IR (mainly IR) polar dust luminosities are ∼2 times larger than the torus ones. The polar-dust temperature decreases while the physical size, estimated by the temperature and dust sublimation radius, increases with AGN luminosity from a few tens of parsec (early mergers) to kiloparsec scales (late mergers), where the polar dust likely comes from expanding (i.e., evolving) dusty outflows. A comparison between the SFRs and intrinsic AGN luminosities suggests that starbursts occur first and AGNs arise later, and overall their growth rates follow the simultaneous coevolution local galaxy–SMBH mass relation. We confirm the coexistence of intense starbursts, AGNs, and large-scale outflows in late mergers, supporting a standard AGN feedback scenario.
Observable Signatures of Stellar-mass Black Holes in Active Galactic Nuclei

Published: March 2023

Abstract
Stellar-mass black holes (BHs) are predicted to be embedded in the disks of active galactic nuclei (AGNs) due to gravitational drag and in situ star formation. However, clear evidence for AGN disk-embedded BHs is currently lacking. Here, as possible electromagnetic signatures of these BHs, we investigate breakout emission from shocks emerging around Blandford–Znajek jets launched from accreting BHs in AGN disks. We assume that most of the highly super-Eddington flow reaches the BH and produces a strong jet, and the jet produces feedback that shuts off accretion and thus leads to episodic flaring. These assumptions, while poorly understood at present, yield observable consequences that can probe the presence of AGN-embedded BHs as well as the accretion process itself. They predict a breakout emission characterized by luminous thermal emission in the X-ray bands and bright broadband nonthermal emission from the infrared to the gamma-ray bands. The flare duration depends on the BH’s distance r from the central supermassive BH, varying between 103–106 s for r ∼ 0.01–1 pc. This emission can be discovered by current and future infrared, optical, and X-ray wide-field surveys and monitoring campaigns of nearby AGNs.

Abstract
We announce the discovery of a main-belt comet (MBC), 2010 LH15 (alternately designated 2010 TJ175). MBCs are a rare type of main-belt asteroid that display comet-like activity, such as tails or comae, caused by sublimation. Consequently, MBCs help us map the location of solar system volatiles, providing insight into the origins of material prerequisite for life as we know it. However, MBCs have proven elusive, with fewer than 20 found among the 1.1 million known main-belt asteroids. This finding derives from Active Asteroids, a NASA Partner Citizen Science program we designed to identify more of these important objects. After volunteers classified an image of 2010 LH15 as showing activity, we carried out a follow-up investigation which revealed evidence of activity from two epochs spanning nearly a decade. This discovery is timely, with 2010 LH15 inbound toward its 2024 March perihelion passage, with potential activity onset as early as late 2023.

Abstract
Remote spectral characterization of near-Earth asteroids (NEAs) relies on laboratory spectral calibration to constrain their surface composition, including mineral chemistry and relative mineral abundances. Often these calibrations are based on fine meteorite powders that are representative of regolith observed on large NEAs such as (433) Eros. However, spacecraft observations of smaller NEAs such as (25143) Itokawa, (101955) Bennu, and (162173) Ryugu show surfaces devoid of a thick layer of regolith and instead find variegated landscapes with millimeter-sized particles to meter-scale boulders. Here we present the results of a laboratory study to understand the effects of grain size on the spectral properties of meteorites and how this can impact ground-based characterization of NEAs. Our study focuses on ordinary chondrites (H, L, LL) and HED meteorites, as they comprise ∼90% of all meteorites that fall on Earth. Compared to ordinary chondrites, the spectral band parameters of HED meteorites are less affected by changing grain size. Among the ordinary chondrites, LL chondrites are least affected, but the spectral band parameters and mineral chemistries and abundances for H and L chondrites are most affected by changing grain size. Grain size does not seem to have any significant effect on the taxonomic classification of our meteorite spectra. We also used the Hapke model to investigate trends in single-scattering albedo as a function of grain size and present equations to recover the grain size from a spectrum.

Abstract
The isotopic signature of atmospheric carbon offers a unique tracer for the history of the Martian atmosphere and the origin of organic matter on Mars. The photolysis of CO2 is known to induce strong isotopic fractionation of the carbon between CO2 and CO. However, its effects on the carbon isotopic compositions in the Martian atmosphere remain uncertain. Here, we develop a 1D photochemical model to consider the isotopic fractionation via photolysis of CO2, to estimate the vertical profiles of the carbon isotopic compositions of CO and CO2 in the Martian atmosphere. We find that CO is depleted in 13C compared with CO2 at each altitude, due to the fractionation via CO2 photolysis: the minimum value of the δ
13C in CO is about −170‰ under the standard eddy diffusion setting. This result supports the hypothesis that fractionated atmospheric CO is responsible for the production of the 13C-depleted organic carbon in the Martian sediments detected by the Curiosity Rover, through the conversion of CO into organic materials and their deposition on the surface. The photolysis and transport-induced fractionation of CO that we report here leads to a ∼15% decrease in the amount of inferred atmospheric loss when combined with the present-day fractionation of the atmosphere and previous studies of carbon escape to space. The fractionated isotopic composition of CO in the Martian atmosphere may be observed by ExoMars Trace Gas Orbiter and ground-based telescopes, and the escaping ion species produced by the fractionated carbon-bearing species may be detected by the Martian Moons eXploration mission in the future.
Enjeux miniers de la transition énergétique : l’exemple de la production du cuivre et du lithium au Chili
Authors: Danino-Perraud Raphaël , Rey-Coquais Solène , Sérandour Audrey 
Published: March 2023

À travers l’analyse de la production de cuivre et de lithium au Chili, cet article s’intéresse aux conditions matérielles de la transition énergétique. Le Chili est en effet le plus grand producteur de cuivre et le second producteur de lithium au monde, deux métaux stratégiques associés à l’électrification des réseaux et à la production d’énergies renouvelables. L’augmentation de la demande mondiale et des prix de ces métaux depuis les années 2000 a de nombreuses conséquences pour le Chili, à différentes échelles. Alors que le marché mondial est de plus en plus dépendant des exportations chiliennes, ce sont aussi, en miroir, les trajectoires de développement nationales qui se trouvent déterminées par les logiques extractives. Elles questionnent particulièrement le rôle des grandes entreprises minières dans le développement territorial, et les impacts environnementaux des acteurs miniers. Dans un contexte de changement climatique, les problématiques écologiques représentent aussi pour les entreprises un enjeu de maintien à court et moyen termes de leurs activités sur leurs territoires d’implantation.
Insecticidal activity of Melaleuca alternifolia (Myrtaceae) essential oil against Tribolium castaneum (Coleoptera: Tenebrionidae) and its inhibitory effects on insecticide resistance development

Abstract
Pests in stored grains pose a global threat to food security. Tribolium castaneum (Coleoptera: Tenebrionidae) is one of the most serious stored-grain pests in the world, capable of surviving harsh environments and developing resistance to certain classes of insecticides. Fumigation toxicity and the impact of Melaleuca alternifolia Cheel (Myrtaceae) essential oil on T. castaneum were investigated in this study. The 50% lethal concentration (LC50) fumigation toxicity of M. alternifolia essential oil for T. castaneum adults and larvae was 122.7 µL/L at 24 hours and 280 µL/L at 48 hours, respectively. Gas chromatography–mass spectrometry showed that the oil’s major volatile compounds included terpinen-4-ol (31.78%), α-terpineol (20.24%), and terpinolene (17.94%). The treatment disrupted the normal enzymatic activity of acetylcholinesterase, carboxylesterase, and glutathione-S-transferase in T. castaneum adults and caused DNA damage. Melaleuca alternifolia essential oil is a strong fumigant and may be a good substitute for synthetic fumigants used to control pests of stored grain.
Zebrafish mavs Is Essential for Antiviral Innate Immunity

Published: March 2023

Abstract
In mammals, the signaling adaptor mitochondrial antiviral signaling protein (MAVS) is a critical determinant in antiviral innate immunity. However, because of the lack of in vivo data, the physiological function of zebrafish mavs in response to viral infection is still not determined. In this study, we demonstrate that the long splicing isoform of zebrafish mavs promotes IFN regulatory factor 3 signaling and NF-κB signaling. Overexpression of this isoform of mavs enhances cellular antiviral responses. Disruption of mavs in zebrafish attenuates survival ratio on challenge with spring viremia of carp virus. Consistently, the antiviral-responsive genes and inflammatory genes are significantly reduced, and the replication of spring viremia of carp virus is increased in mavs-null zebrafish. Therefore, we provide in vivo evidence to support that zebrafish mavs is essential for antiviral innate immunity, similar to mammalian MAVS.
Multiomics Empowers Predictive Pancreatic Cancer Immunotherapy

Published: March 2023

Abstract
Advances in cancer immunotherapy, particularly immune checkpoint inhibitors, have dramatically improved the prognosis for patients with metastatic melanoma and other previously incurable cancers. However, patients with pancreatic ductal adenocarcinoma (PDAC) generally do not respond to these therapies. PDAC is exceptionally difficult to treat because of its often late stage at diagnosis, modest mutation burden, and notoriously complex and immunosuppressive tumor microenvironment. Simultaneously interrogating features of cancer, immune, and other cellular components of the PDAC tumor microenvironment is therefore crucial for identifying biomarkers of immunotherapeutic resistance and response. Notably, single-cell and multiomics technologies, along with the analytical tools for interpreting corresponding data, are facilitating discoveries of the systems-level cellular and molecular interactions contributing to the overall resistance of PDAC to immunotherapy. Thus, in this review, we will explore how multiomics and single-cell analyses provide the unprecedented opportunity to identify biomarkers of resistance and response to successfully sensitize PDAC to immunotherapy.

The article critically examines literary data on glaciers and glacial lakes located in the Midagrabindon river basin and changes that have occurred on them over the past half century. In 1977, there were 12 glaciers and 3 lakes in this territory. Now there are 30 glaciers, 5 active rock glaciers and 16 glacial lakes. A map of glaciers, rock glaciers and glacial lakes of the Midagrabindon River basin has been compiled. Morphometric data are given in Tables. Glaciation degradation is increasing. Due to the ongoing warming of the climate, the degradation of glaciation is increasing. Perhaps this process is influenced by the dormant volcano Kazbek.
