В статье приводится шестилетний опыт участия специалистов РНПЦ ОМР им. Н.Н. Александрова в проведении Европейской недели ранней диагностики опухолей головы и шеи. Результаты бесплатных профилактических осмотров мультидисциплинарной бригадой врачей показали, что подобные мероприятия не ставят целью выявить как можно больше онкологических заболеваний данной локализации (доля пациентов со злокачественными новообразованиями составляет 3–4% от числа обратившихся к специалистам), но призваны привлечь внимание к этой проблеме и повысить осведомленность о раке головы и шеи населения и медицинских работников. Обязательным мероприятием Европейской недели ранней диагностики рака головы и шеи стало проведение республиканских научно-практических конференций и семинаров для обсуждения проблем ранней диагностики опухолей головы и шеи, взаимодействия специалистов, принимающих участие в диагностическом поиске и лечении опухолей головы и шеи.
The article provides a six-year experience of participation of the specialists from the N.N. Aleksan- drov National Cancer Center of Belarus in the Awareness Week for early diagnostics of head and neck cancer. The results of free preventive examinations by a multidisciplinary team of doctors showed that such events do not aim to identify as many oncological diseases of the given localization as possible (the proportion of patients with malignant neoplasms is 3–4% of the number of those, who applied to specialists), but they are designed to draw attention to this problem and increase head and neck cancer awareness among the general public and healthcare professionals. An obligatory event of the European week for early diagnostics of head and neck cancer was the republican sci- entific and practical conferences and seminars to discuss the problems of early diagnostics of head and neck tumors and interaction of specialists involved in the diagnostic search and treatment of head and neck tumors.

On the Dichromatic Number of Surfaces
Authors: Aboulker Pierre , Havet Frédéric , Knauer Kolja , Rambaud Clément 
Published: February 2022

In this paper, we give bounds on the dichromatic number $\vec{\chi}(\Sigma)$ of a surface $\Sigma$, which is the maximum dichromatic number of an oriented graph embeddable on $\Sigma$. We determine the asymptotic behaviour of $\vec{\chi}(\Sigma)$ by showing that there exist constants $a_1$ and $a_2$ such that, $ a_1\frac{\sqrt{-c}}{\log(-c)} \leq \vec{\chi}(\Sigma) \leq a_2 \frac{\sqrt{-c}}{\log(-c)} $ for every surface $\Sigma$ with Euler characteristic $c\leq -2$. We then give more explicit bounds for some surfaces with high Euler characteristic. In particular, we show that the dichromatic numbers of the projective plane $\mathbb{N}_1$, the Klein bottle $\mathbb{N}_2$, the torus $\mathbb{S}_1$, and Dyck's surface $\mathbb{N}_3$ are all equal to $3$, and that the dichromatic numbers of the $5$-torus $\mathbb{S}_5$ and the $10$-cross surface $\mathbb{N}_{10}$ are equal to $4$. We also consider the complexity of deciding whether a given digraph or oriented graph embeddable on a fixed surface is $k$-dicolourable. In particular, we show that for any fixed surface, deciding whether a digraph embeddable on this surface is $2$-dicolourable is NP-complete, and that deciding whether a planar oriented graph is $2$-dicolourable is NP-complete unless all planar oriented graphs are $2$-dicolourable (which was conjectured by Neumann-Lara).

Homologous Accelerated Electron Beams, a Quasiperiodic Fast-propagating Wave, and a Coronal Mass Ejection Observed in One Fan-spine Jet

Published: February 2022

Abstract
Using imaging and radio multi-wavelength observations, we studied the origin of two homologous accelerated electron beams and a quasiperiodic fast-propagating (QFP) wave train associated with a solar jet on 2012 July 14. The jet occurred in a small-scale fan-spine magnetic system embedded in a large-scale pseudostreamer associated with a GOES C1.4 flare, a jet-like coronal mass ejection (CME), a type II radio burst, and a type III radio burst. During the initial stage, a QFP wave train and a fast-moving on-disk radio source were detected in succession ahead of the jet along the outer spine of the fan-spine system. When the jet reached a height of about 1.3 solar radii, it underwent a bifurcation into two branches. Based on our analysis results, all the observed phenomena in association with the jet can be explained by using a fan-spine magnetic system. We propose that both the type III radio burst and the on-disk fast-moving radio source were caused by the same physical process, i.e., energetic electrons accelerated by magnetic reconnection at the null point, and these energetic electrons were propagating along the open field lines of the pseudostreamer and the closed outer spine of the fan-spine structure, respectively. Due to the bifurcation of the jet body, the lower branch along the closed outer spine of the fan-spine structure fell back to the solar surface, while the upper branch along the open field lines of the pseudostreamer caused the jet-like CME in the outer corona.
Thermophysical Investigation of Asteroid Surfaces. II. Factors Influencing Grain Size
Authors: MacLennan Eric M. , Emery Joshua P. 
Published: February 2022

AbstractAsteroid surfaces are subjected to mechanical weathering processes that result in the development and evolution of regolith. Two proposed mechanisms—impact bombardment and thermal fatigue—have been proposed as viable and dominant weathering processes. Previously, we compiled and estimated thermal inertias of several hundred asteroids (mostly in the main belt) for which we determined dependencies on temperature, diameter, and rotation period. In this work, we estimate grain sizes of asteroid regoliths from this large thermal inertia data set using thermal conductivity models. Following our previous work, we perform multivariate linear model fits to the grain size data set and quantify its dependency on diameter and rotation period. We find that the preferred model indicates that asteroid grain sizes are inversely dependent on object size for <10 km asteroids and exhibit no relationship above this size cutoff. Rotation period and grain size show a positive relationship when the rotation period is greater than ∼5 hr and an inverse relationship below this rotation period. These results indicate that both impact weathering and thermal fatigue are relevant regolith evolution mechanisms. We run post-hoct-tests between spectral groups to infer the influence of composition on regolith grain sizes. We find that M-type (including suspected metal-rich objects) and E-type asteroids have larger grain sizes relative to our population sample and that P-type asteroids have distinctly smaller grains than other groups.
High-resolution Search for Kuiper Belt Object Binaries from New Horizons

Published: February 2022

Abstract
Using the New Horizons LOng Range Reconnaissance Imager camera, we searched for satellites near five Kuiper Belt objects (KBOs): four cold classicals (CCs: 2011 JY31, 2014 OS393, 2014 PN70, 2011 HZ102) and one scattered disk (SD) object (2011 HK103). These objects were observed at distances of 0.092–0.290 au from the New Horizons spacecraft, achieving spatial resolutions of 136–430 km (resolution ∼2 camera pixels), much higher than possible from any other facilities. Here we report that CC 2011 JY31 is a binary system with roughly equal brightness components, CC 2014 OS393 is likely an equal-brightness binary system, while the three other KBOs did not show any evidence of binarity. The JY31 binary has a semimajor axis of 198.6 ± 2.9 km, an orbital inclination of 61.°34 ± 1.°34, and an orbital period of 1.940 ± 0.002 days. The OS393 binary objects have an apparent separation of ∼150 km, making JY31 and OS393 the tightest KBO binary systems ever resolved. Both HK103 and HZ102 were detected with a signal-to-noise ratio (S/N) ≈ 10, and our observations rule out equal-brightness binaries with separations larger than ∼430 km and ∼260 km, respectively. The spatial resolution for PN70 was ∼200 km, but this object had a S/N ≈ 2.5–3, which limited our ability to probe its binarity. The binary frequency for the CC binaries probed in our small survey (67%, not including PN70) is consistent with the high binary frequency suggested by larger surveys of CCs and recent planetesimal formation models, but we extend the results to smaller orbit semimajor axes and smaller objects than previously possible.

Abstract
BACKGROUND: Experimental data on the effect of a high dose of gamma radiation 6 Gy on the activity of antioxidant defense enzymes and lipid peroxidation products (LPO) are presented immunocompetent organs in the body of animals in the experiment. It was found that the effect of ionizing radiation led to an increase in the level of diene conjugates (DC) and malondialdehyde (MDA), inhibition of the activity of catalase (CАT) and glutathione peroxidase (GlP), glutathione reductase (GlR) enzymes in almost all the studied objects, as a result of which the development of oxidative stress was observed in them. The results of the study indicate serious changes in the lipid peroxidation and antioxidant system (AOS) under radiation stress. An imbalance of POL-AOS creates prerequisites for the occurrence of immunopathological conditions, contributing to the development of radiation-related tumor infection. pathologies. Violations of functional relationships of the catalytic redox system.
AIM: The aim of the study was to study the effect of radiation at a dose of 6 Gy on the parameters of lipoperoxidation and the antioxidant system in experimental rats.
MATERIAL AND METHODS: The work was carried out on 20 male Wistar rats weighing 240 ± 20 g. Experimental animals are divided into two groups: I - normal group; II - group exposed to γ-rays at a dose of 6 Gy.
RESULTS: After radiation exposure, all objects showed a tendency to increase the product of lipid peroxidation. As is known, the activation of lipid peroxidation is based on excessive generation of reactive oxygen species, which exceeds the physiological capabilities of antioxidant systems that occur after the depletion of enzyme systems.
CONCLUSION: Based on the results obtained, it was found, that irradiation increases the intensity of the formation of POL products and their accumulation, reduces the activity of enzymes of the antioxidant system in immunocompetent organs in irradiated animals, as a result, the lack of the antioxidant system causes oxidative stress in the body.

En vue de mieux appréhender le niveau de connaissance de la population ivoirienne sur l’espèce Euphorbia heterophylla et d’enrichir la pharmacopée ivoirienne, une étude ethnobotanique a été réalisée. Elle s’est faite à partir d’une prospection au cours de laquelle des échantillons de plantes ont été prélevés dans les cinq zones géographiques de la Côte d’Ivoire, suivie d’une enquête dans certaines localités. La prospection a permis de ressortir 3 morphotypes caractérisés par 3 formes de tige : unique, peu ramifiée et très ramifiée ainsi que 3 formes de feuilles : ovale, violon et lancéolée. Sur le plan culturel, l’étude a révélé que 75% des personnes enquêtées connaissent la plante, 55% la considèrent comme mauvaise herbe, 13,39% estiment qu’elle sert à prodiguer des soins de santé aux humains. L’organe le plus utilisé est la feuille pour les soins à 100%. Le mode de préparation le plus utilisé est le broyage de feuilles fraîches ou l’expression. Les modes d’applications sont surtout cutanés (90%). Elle est fréquemment utilisée pour le traitement du paludisme, soit 33% des cas. Les autres soins prodigués allaient contre les maladies infantiles dont la fièvre (11%) et d’autres maux. Ces résultats peuvent servir de base de recherches en phytochimie et en pharmacologie.
