Abstract
The SARS-CoV-2 virus initiates infection of human cells by recognizing the human angiotensin-converting enzyme 2 (ACE2) with the receptor binding domain (RBD) of the viral spike protein. Thus, the variant of concern (VOC) with mutations on RBD is of special interest. Here, we present a series of interaction analyses for the RBD–ACE2 complex of the wild-type (PDB ID: 6M0J) and those of B.1.1.7 (α), B.1.351 (β) and P.1 (γ) VOCs, based on the fragment molecular orbital (FMO) calculations. The results revealed that the RBD variants have a higher affinity for ACE2 than the wild type does.
Direct growth of GaN on sapphire substrate via polarity transition from N- to Ga-polar using only hydride vapor phase epitaxy

Abstract
We established a method for directly growing the GaN layer on a sapphire substrate using only hydride vapor phase epitaxy (HVPE). The important factors that affect the manufacture of high-quality, low-cost, and large-diameter GaN substrates require a growth method that does not utilize either a GaN template or processes other than HVPE. N2 carrier gas and a high temperature are important growth parameters required to achieve the direct growth of the GaN layer on the sapphire substrate. The mechanism of the direct growth of the GaN layer on the sapphire substrate reveals that the N-polar GaN layer grows during the initial growth stage via the nitridation of the sapphire substrate and Ga-polar GaN is subsequently produced via polarity inversion. Furthermore, the dislocation density of the GaN layer directly grown on the sapphire substrate is lower than that of the GaN layer grown on a GaN template using metal-organic vapor phase epitaxy.

GENRE OF THE EPISTLE IN THE LYRICS BY M. I. NOVJUKHOV
Authors: Косинцева Е.В. 
Published: July 2021

В истории хантыйской литературы к жанру послания обратился только Матвей Иванович Новьюхов. В данной статье анализу подвергаются послания, вошедшие в книгу М.И. Новьюхова «С надеждой на счастье» (2012). Хантыйским поэтом представлены дружеские, любовные послания и послания-письма родным. Диалогическая природа жанра сильнее всего проявилась в дружеских и любовных посланиях хантыйского стихотворца. Диалог с мансийским поэтом Юваном Шесталовым позволил автору размышлять о месте и роли поэта в обществе. М.И. Новьюхов подчеркивает высокое предназначение поэта в жизни общества, не случайно в одном из посланий к основоположнику мансийской литературы он ставит рядом два понятия «поэт» и «гражданин». Частная жизнь и биографические реалии ярче представлены в любовных посланиях и посланиях-письмах к родным. Послания к членам семьи (брату, дочери) носят характер личной беседы. Образцы любовного послания содержит трогательные признания, адресованные возлюбленной.
In the history of Khanty literature, only Matvey Ivanovich Novlukhov addressed to the genre of the epistle. The article analyzes the epistles included in the book of M. I. Novjukhov "With Hope For Happiness" (2012). The Khanty poet presents the friendly, love epistles and letters to relatives. The dialogic nature of the genre was most strongly manifested in the friendly and love epistles. The dialogue with the Mansi poet Yuvan Shestalov allowed the author to reflect on the place and role of a poet in society. Novjukhov emphasizes the high purpose of a poet in the life of society. It is no coincidence that in one of the epistles to the founder of Mansi literature, he puts the two concepts of "poet" and "citizen" side by side. Private life and biographical realities are more vividly represented in love epistles and letters to relatives. The epistles to family members (brother, daughter) are in the nature of a personal conversation. Samples of love epistles contain heartwarming declarations of love addressed to his beloved.
TERMINOLOGY OF HANDMADE IN MODERN RUSSIAN LANGUAGE: FEATURES OF FUNCTIONING AND FIXATION
Authors: Меркулова И.А. , Паненко М.В. 
Published: July 2021

В статье рассматриваются специфические черты терминологии хендмейд - творческой деятельности, связанной с созданием изделий ручной работы. В современном русском языке это динамически развивающаяся область терминообразования, которая требует лингвистического описания и словарной фиксации. Объектом исследования являются лексические единицы тематической группы «Хендмейд» в количестве около 200 слов. Целью исследования является определение состава и особенностей данной терминологии. С одной стороны, она демонстрирует основные черты отраслевой терминологии, с другой, - для терминологии хендмейд характерны образность, экспрессивность, полисемия, что показано на примерах. Данная терминология формируется преимущественно стихийно в рамках разговорной профессиональной коммуникации в интернет-дискурсе. Выделяются шесть основных тематических групп рассматриваемых терминов. Терминологию хендмейд можно рассматривать как систему систем, так как вокруг центрального понятия «техника или вид рукоделия» формируется разветвленная система номинаций, связанных с этой понятийной областью. Терминология хендмейд не имеет лексикографической фиксации в виде специального словаря, и нормы правописания многих слов еще только формируются. Очевидно, что в дефиницию подобных лексических номинаций желательно включать элементы толкования, а сам словарь считать толково-дефиниционным.
The article studies the specific features of hand-made (creative activity associated with handwork) terminology. This is a dynamically developing area of the term formation in modern Russian, which requires linguistic description and dictionary fixation. The object of the research is the lexical units of the thematic group "Handmade" in the amount of about 200 words. The purpose of the research is to determine the composition and features of this terminology. On the one hand, it demonstrates the main features of industry terminology. On the other hand, handmade terminology is characterized by imagery, expressiveness, polysemy, as shown in examples. This terminology is formed mainly spontaneously in the framework of spoken professional communication in the Internet discourse. There are six main thematic vocabulary groups. Handmade terminology can be viewed as a system of systems. Around the central concept of “technique or type of handiwork” is formed a ramified system of nominations. Handmade terminology does not have a lexicographic fixation in the special dictionary, and the spelling norms of many words are still being formed. Obviously, that the definition of such lexical nominations should include elements of interpretation. And the dictionary itself should be considered explanatory and definitional.

Memory precision for salient distractors decreases with learned suppression

Published: July 2021

AbstractAttention operates as a cognitive gate that selects sensory information for entry into memory and awareness (Driver, 2001, British Journal of Psychology, 92, 53–78). Under many circumstances, the selected information is task-relevant and important to remember, but sometimes perceptually salient nontarget objects will capture attention and enter into awareness despite their irrelevance (Adams & Gaspelin, 2020, Attention, Perception, & Psychophysics, 82[4], 1586–1598). Recent studies have shown that repeated exposures with salient distractor will diminish their ability to capture attention, but the relationship between suppression and later cognitive processes such as memory and awareness remains unclear. If learned attentional suppression (indicated by reduced capture costs) occurs at the sensory level and prevents readout to other cognitive processes, one would expect memory and awareness to dimmish commensurate with improved suppression. Here, we test this hypothesis by measuring memory precision and awareness of salient nontargets over repeated exposures as capture costs decreased. Our results show that stronger learned suppression is accompanied by reductions in memory precision and confidence in having seen a color singleton at all, suggesting that such suppression operates at the sensory level to prevent further processing of the distractor object.
The North Carolina Libraries Centennial Oral History Project
Authors: Cherry Thomas Kevin 
Published: July 2021

Libraries and librarians have been among the chief promoters and supporters of oral history programs. Not only have they collected, preserved, and made accessible the taped interviews conducted by microphone-toting historians, but, in a great many cases, libraries and librarians actually have been the sponsors of oral history projects and programs. In some notable instances, it has been the librarian wielding the microphone. Over the years, libraries have teamed oral history with everything from bookmobile service to children’s programming, classroom projects, and local history and genealogy activities.

Revealing the Physical Conditions around Sgr A* Using Bayesian Inference. I. Observations and Radiative Transfer

Published: July 2021

AbstractWe report subarcsecond Atacama Large Millimeter/submillimeter Array (ALMA) observations between 272 and 375 GHz toward Sgr A*'s circumnuclear disk (CND). Our data comprise eight individual pointings, with significant SiO (87–76) and SO (7–6) emission detected toward 98 positions within these pointings. Additionally, we identify H2CS (91,9–81,8), OCS (25–24), and CH3OH (21,1–20,2) toward a smaller subset of positions. By using the observed peak line flux density, together with a Bayesian inference technique informed by radiative transfer models, we systematically recover the physical gas conditions toward each of these positions. We estimate that the bulk of the surveyed gas has temperatureTkin< 500 K and densitynH⪅ 106cm−3, consistent with previous studies of similar positions as traced by HCN clumps. However, we identify an uncharacteristically hot (Tkin≈ 600 K) and dense (nH≈ 106cm−3) source in the Northeastern Arm. This position is found to be approximately consistent with a gravitationally bound region dominated by turbulence. We also identify a nearby cold (Tkin≈ 60 K) and extremely dense (nH≈ 107cm−3) position that is again potentially bound and dominated by turbulence. We also determine that the total gas mass contained within the CND isMCND≲ 4 × 104M⊙. Furthermore, we qualitatively note that the observed chemical enrichment across large scales within the CND is consistent with bulk grain processing, though multiple desorption mechanisms are plausibly responsible. Further chemical modeling is required to identify the physical origin of the grain processing, as well as the localized H2CS and OCS emission.
Transovarial effect of novaluron: persistence and residual effects on Stephanitis pyrioides (Hemiptera: Tingidae)
Authors: Joseph Shimat V. 
Published: July 2021

AbstractStephanitis pyrioides (Scott) (Hemiptera: Tingidae) is an important insect pest of azaleas, Rhododendron Linnaeus spp. (Ericaceae), in the United States of America. Because neonicotinoids, insecticides traditionally used against S. pyrioides, pose a risk to pollinators and natural enemies, nursery growers have reduced neonicotinoid use and are seeking alternative management options. Novaluron, an insect growth regulator, elicits a transovarial effect by reducing the viability of eggs after exposure to S. pyrioides adults. However, stability and persistence of transovarial effects on adults following exposure are not clear. The objectives of this study were to determine (1) the persistence of the transovarial effect of novaluron for up to three weeks after a single adult exposure and (2) the residual activity of aged novaluron residues eliciting a transovarial effect against S. pyrioides after a single application. Stephanitis pyrioides density was significantly lower in the novaluron-treated adults than in the nontreated controls for up to 21 days. The novaluron residues deposited on azalea foliage aged up to 32 days significantly reduced the number of S. pyrioides nymphs compared to that of the nontreated control. There was no significant difference in the number of nymphs among the 7-, 17-, and 32-day-old novaluron treatments relative to the nontreated control.

Published: July 2021

PURPOSE:
The purpose of this study is to compare the corneal biomechanical properties of hyperthyroids without ophthalmopathy (HWO), thyroid eye disease (TED), and euthyroid participants.

METHODS:
In this prospective comparative study, one eye per patient included in the analysis and according to exclusion criteria, 38 eyes of 40 HWO patients, 31 eyes of 40 TED patients, and 150 eyes of 160 age- and sex-matched euthyroid participants were enrolled. All participants were evaluated by an endocrinologist and oculoplastic surgeon for evaluation of thyroid function and orbitopathy, respectively. Measurements of corneal biomechanical properties were performed using ocular response analyzer and Corvis ST tonometers.

RESULTS:
In the HWO group, applanation-1 length (A1 L), applanation-2 velocity (A2V) (P < 0.001), and corneal resistant factor (P = 0.043) were higher than the control group and corneal hysteresis (CH) was lower (P = 0.018). In the TED group, A1 L, A2V (P < 0.001), and highest concavity radius (HCR) (P = 0.027) were higher than the control group, and the CH (P = 0.007) and highest concavity deformation amplitude (HCDA) (P = 0.001) were lower. Furthermore, the level HCDA in the TED group was lower than HWO group (P = 0.011). The level of upper scleral show and palpebral fissure had a negative correlation with CH and HCDA. The amount of exophthalmos level had a positive correlation with HCR.

CONCLUSION:
Corneal biomechanical properties in the HWO and TED groups were different from the normal euthyroid individuals and may be taken into account in managing situation like glaucoma and refractive surgeries.
