The tenacity of culture as represented by the Chinese color term Qing
Authors: Wang Jun , Guan Chenghui 
Published: September 2022

Abstract

qing (青) is a very special and controversial color term in Chinese language and culture for the fact that it can refer to green, blue, or black depending on how it is used in collocation or context; it can be used as both a basic color term and mixed color term; in context it can be understood to refer to a certain color, but sometimes nobody can tell for sure what specific color it refers to; it can refer to color, but in more situations the understanding of it just goes beyond the perception of color, bringing about a vague but delightful feeling about the world in general. Basic as well as associative meanings of this term existed at the early stage of its creation, and these meanings can still be perceived in various situations in modern Chinese, used in much more extensive way. To a large extent, it has become a rather peculiar sign of Chinese culture, held so firmly, dearly and lastingly by the Chinese people. The case of qing serves as a typical example that reflects how the Chinese perceive the world.
Multimodal positive discourse analysis of national image publicity video
Authors: Guan Chenghui 
Published: September 2022

AbstractThis study employs a revised theoretical framework of multimodal positive discourse analysis to analyze the process of national image construction in a Chinese video. In contrast to original studies focusing mainly on language or text and image, this study considers three interrelated multimodal resources: sound, image, and language. Different modalities play different roles in national image construction, and they also collaborate with each other for a uniform purpose. Specific multimodal working mechanisms contribute to the construction of a positive national image. Multimodal resources are also signs in the sense of semiotics, which are perceived by different sense organs and take effect in producing vivid and impressive senses.

Authors: Zheng Lin , Chen Liang , Tang Yangxin 
Published: September 2022

Abstract
In this article, we analyze the convergence rate of the modified Levenberg-Marquardt (MLM) method under the Hölderian local error bound condition and the Hölderian continuity of the Jacobian, which are more general than the local error bound condition and the Lipschitz continuity of the Jacobian. Under special circumstances, the convergence rate of the MLM method coincides with the results presented by Fan. A globally convergent MLM algorithm by the trust region technique will also be given.
On the Hochschild cohomology of a map between commutative differential graded algebras
Authors: Maphane Oteng , Gatsinzi Jean-Baptiste 
Published: September 2022

AbstractWe consider a surjective morphism between commutative differential graded algebrasϕ: (∧V,d) → (B,d), whereVis finite dimensional, and (B,d) is a module over ∧Vvia the mappingϕ. We show that the Hochschild cohomologyHH*(∧V;B) can be computed in terms of the graded vector space of positiveϕ-derivations. Moreover, ifVis finite dimensional, thenHH*(∧V;B) contains a polynomial algebra.

Authors: Allahyari Fakhri , Molaee Hamideh , Hosseini Nejad Javad 
Published: September 2022

Abstract
The COVID-19 mainly causes respiratory disorders with high infection and severe morbidity and mortality. Neurologists have concerns about potential neurological side effects, profits, and timing of COVID-19 vaccines. This study aimed to review systematically research for the COVID-19 vaccine and neurological complications. Data was searched in Scopus, ISI web of knowledge, Medline, PubMed, Wiley, Embase, International Clinical Trials Registry Platform and Clinical Trials, Cochrane Library, and Google Scholar. Two reviewer authors individually searched and assessed the titles and abstracts of all articles. The third reviewer resolved disagreement between them. Data were documented regarding study location, study design, type of complications, number of patients, various types of COVID-19 vaccine, and type of neurological complications. Six studies in COVID-19 vaccine and neurological complications include two studies about neurological manifestations after the mRNA vaccines, four records about side effects of vector-based vaccine were included in the study. The main neurological complication associated mRNA vaccines were body aches, paresthesia, and difficulty walking, erythema migrans lesion, fatigue, myalgia, and pain in the left lateral deltoid region. The major neurological complication related to vector-based vaccines were urinary retention difficulty, feeding and ambulating, arm soreness, mild fatigue, chills, left-sided facial droop, headaches, a generalized epileptic seizure, hemianopia, and mild aphasia, acute somnolence and right-hand hemiparesis, acute transverse myelitis, deep vein thrombosis in her left leg, a vigilance disorder and a twitching, a severe immobilizing opsoclonus myoclonus syndrome, and encephalitis. A large spectrum of severe neurological unfavorable has been reported. These complications could occur as a result of molecular stimulation and later neuronal damage. Generally, the advantages of COVID‐19 vaccination are dominant on the risks of a neurological complication at both individual and population levels. Future investigations will be required to find any relationship between neurological complications and COVID‐19 vaccines principally as new strains of the virus and new vaccines are technologically advanced against them.
Investigation of thermoelectric material based on Lu1-xZrxNiSb solid solution. II. Modeling of characteristics

Published: September 2022

The KKR (AkaiKKR software package) and FLAPW (Elk software package) methods were used to model the structural, thermodynamic, energetic, and electrokinetic characteristics of the Lu1-xZrxNiSb semiconductor solid solution. It is shown that defects of acceptor nature are present in the structure of LuNiSb as a result of vacancies in positions 4a and 4c of Lu and Ni atoms, respectively, which generates two acceptor levels eAVac 4a and eAVac 4c in the band gap εg. When Zr atoms are introduced into the LuNiSb structure by replacing Lu atoms in position 4a, Zr atoms also occupy vacancies in this position, which increases the lattice parameter a(x) and eliminates defects of acceptor nature and corresponding acceptor levels eAVac 4a. When the vacancies are filled, Lu atoms are displaced, which reduces the value of the unit cell parameter and generates defects of donor nature and donor levels eD4a. The Ni atoms return to position 4c, which increases the a(x) value and eliminates defects of acceptor nature and the corresponding acceptor levels eAVac 4c. At the lowest concentration of Zr atoms, the conduction type of Lu1-xZrxNiSb changes from p- to n-type. The simulation results are consistent with experimental studies of Lu1-xZrxNiSb.
Inner Regions and Interval Linearizations for Global Optimization
Authors: Trombettoni Gilles , Araya Ignacio , Neveu Bertrand , Chabert Gilles 
Published: September 2022

Researchers from interval analysis and constraint (logic) programming communities have studied intervals for their ability to manage infinite solution sets of numerical constraint systems. In particular, inner regions represent subsets of the search space in which all points are solutions. Our main contribution is the use of recent and new inner region extraction algorithms in the upper bounding phase of constrained global optimization. Convexification is a major key for efficiently lower bounding the objective function. We have adapted the convex interval taylorization proposed by Lin and Stadherr for producing a reliable outer and inner polyhedral approximation of the solution set and alinearization of the objective function. Other original ingredients are part of our optimizer, including an efficient interval constraint propagation algorithm exploiting monotonicity of functions. We end up with a new framework for reliable continuous constrained global optimization. Our interval B&B is implemented in the interval-based explorer Ibex and extends this free C++ library. Our strategy outperforms the best reliable global optimizers.

Background. Real world data help to provide more information on the effects and tolerability of therapy. However, data on the use of perampanel in Russian population of children remain limited.Aim. To conduct a retrospective analysis of perampanel efficacy and tolerability in children and adolescents with epilepsy in real clinical practice.Materials and methods. A total of 106 children aged 4–18 years receiving perampanel as part of combination therapy for epilepsy were observed at 18 centers. Seizure frequency at 1–3, after 6 and 12 months of treatment, presence and type of adverse events (AEs) were analyzed. The main assessed efficacy parameters were seizure control, significant (≥50 %) decrease in seizure frequency. All other outcomes (<50 % decrease, no change or increased seizure frequency) were considered to be no effect. The assessed safety parameters were the percentage of patients with or without AEs and the percentage of perampanel withdrawals due to AEs.Results. We defined 3 age groups for comparison: children 4–6, 7–11 and 12–17 years old. Perampanel efficacy was 69 % (seizure control – 23.6 %, ≥50 % decrease in seizure frequency – 45.3 %). The mean duration of the effect was 7.3 ± 4.1 months. No significant difference in efficacy between age groups was found. However, some greater efficacy of perampanel was noted in adolescents: absence of effect in the form of remission or significant decrease in seizures frequency was noted only in 25.5 %, with 40 % in children 4–11 years old. Among those with inefficacy, 3.8 % reported seizure aggravation. AEs occurred in only 23 % of patients, with the least frequent occurrence in adolescents (11.8 %) and the most frequent in children aged 7–11 years (40 %). The most frequent AEs was sluggishness and/or drowsiness. Discontinuation of perampanel due to AEs was required in 7.6 %.Conclusion. Perampanel has demonstrated high efficacy and good tolerability in real clinical practice among children from 4 years of age and adolescents with partial (focal) and secondary generalized seizures. The AEs that developed were not serious and very rarely led to withdrawal of the therapy. The results are comparable to those of phase III studies and previous real-world data. The usage of perampanel in children with primary generalized seizures should be further investigated.
Perception of the organization's safety culture by medical staff in Germany and Russia
Authors: Tsaranov K. N. 
Published: September 2022

Purpose of the study. To compare the perception of the safety culture of the organisation by medical staff in Germany and Russia.Materials and methods. In the study carried out in Germany (Bohmann F. O. et al.), the original Safety Attitudes Questionnaire (SAQ), was used. The Russian sample, an adapted and validated Russian-language version of the questionnaire was used (Tsaranov, K.N. et al.).Results. According to the indicator "Experience of work" among German medical workers, the results of the questionnaire showed higher results for all of the studied indicators except "Stress recognition" in the group of medics with more than 5 years of work experience. Among Russian medics higher results were observed in the group of respondents with less than 5 years of work experience except for the "Perceptions of management".For the indicator "professional position" among medics in Germany, the results of the questionnaire showed higher results for all of the studied indicators in the group of medics who occupy the professional position of "physician". In Russia nursing staff score higher on the "Working conditions" factor, while physicians score higher on "Teamwork climate", "Safety climate" and "Stress recognition", showed a coincidence of results on "Job satisfaction" and "Perceptions of management" scales.The neuroradiology department scores higher than the neurology department of German clinics on the factors "Teamwork climate", "Safety climate", "Job satisfaction" and "Working conditions". The coincidence with the results of the mean values in both groups is observed for the factor "Perceptions of management". Russia has the highest scores for most of the factors: "Safety climate", "Job satisfaction", "Perceptions of management" and "Working conditions" were shown by the staff in the reception and diagnostic department. Low scores were found for the factors "Teamwork climate" and "Safety climate" among staff in the infectious diseases department, and "Stress recognition" in the intensive care and combustiology departments.Conclusion. Significant differences were revealed according to the indices "length of professional experience", "professional position" and "department of work" among employees of medical clinics in Russia and Germany. The results enable the identification of target points for the design of a medical organisation development program aimed at increasing the level of evaluation of the safety culture of a medical organisation.

Purpose of the study. To study the effect of copper nanoparticles on the characteristics of the transplanted tumors of rats, as well as to assess the dependence of the effect on the method of administration of nanoparticles.Materials and methods. In experiments on 163 white outbred male rats, 160–200 g, the size and growth rate of transplanted sarcoma 45 and Pliss' lymphosarcoma were determined in dynamics when a suspension of copper nanoparticles in physiological saline was injected intratumorally or intraperitoneally in a total dose of 10 mg/kg. Nanoparticles had a "core-shell" structure with variable diameter in the range of 30–75 nm. Contrary to other researches, we started the exposure to metal nanoparticles only when the tumors had become visible and had grown up to the sizes at which their spontaneous regression was unlikely.Results. In most animals (up to 89 %), significant antitumor effects of copper nanoparticles were obtained up to complete regression of tumors with large volumes. The effects of nanodispersed copper differed in tumors with different histological structures and growth patterns. Experiments on a transplantable, slowly growing sarcoma 45 showed a decrease in the specific tumor growth rate after a single injection of nanoparticles (1.25 mg/kg), a decrease in tumor size could be observed after 4 injections (a total dose of 5 mg/kg). In the case of a rapidly growing tumor model (Pliss' lymphosarcoma), a decrease in tumor growth rates caused by copper nanoparticles occurred at later stages of exposure, after the animals received nanoparticles at a total dose of 5–10 mg/kg. The efficiency depended on the approach of nanoparticles injection.Conclusion. In case of sarcoma 45, intraperitoneal injection of copper nanoparticles was more effective than intratumoral one, while in rats with Pliss' lymphosarcoma intratumoral injection of the nanoparticles had some advantages. The results indicate that nanodispersed copper is a promising antitumor factor. The mechanisms of regression of large transplanted tumors under the influence of copper nanoparticles are discussed.

Purpose of the study. The study was aimed to investigate the effectiveness of PET / CT with 18 fluoro‑2 deoxy-D-glucose (18F-FDG) in the differential diagnosis of focal lung neoplasms.Materials and methods. Patients (n = 108) with newly diagnosed lung focal lesions were enrolled in the study. All patients underwent PET / CT with 18fluoro‑2deoxy-D-glucose in the "whole body" mode in accordance with the standard protocol. The next step was surgical treatment with morphological verification. According to the results of the morphological conclusion, malignant neoplasm was not diagnosed in 11 (10.2 %) patients, while post-inflammatory changes were detected in 7 patients (SUVmax from 2.3 to 15.15), hamartoma was verified in 3 patients (SUVmax from 1.1 to 4.2) and anthracosis was detected in 1 patient.Results. The median radiopharmaceutical accumulation (SUVmax) was 6.0 (ICR 3.9–8.4, n = 108). In turn, in patients with diagnosed lung cancer this indicator was 7.0 (ICR 5.8–10.9, n = 60), in patients with metastatic lesions 4.3 (ICR 2.5–7.1, n = 37). The threshold for SUVmax was 5.4 for the detection of malignant tumors. PET/CT with 18F-FDG demonstrated high data variability regarding the size of lung focal lesion. An error within 35 % was observed in 76 % of cases, underestimating small lesions (up to 40 mm) but overestimating the major neoplasms. Application of a linear model for adjustment of neoplasm size assessment allows to estimate the actual size of neoplasms with parameters 5.862 + 0,817 × х (х – PET / CT size) in 84.5 % of cases with an error of 50 %. The optimal diagnosing size for metastatic lesions is in the range between 16.4 and 19 mm.Conclusion. Taken together the results of the study show that PET / CT with 18F-FDG gives a relatively accurate estimation of the tumor size. Application of the linear model corrects a radiological size measurements and helps to predict an actual size of a neoplasm in 84.5 % of cases with an error of 50 %. The prospective threshold for SUVmax was at least 5.4 for the detection of malignant neoplasms.

Purpose of the study. The aim of this work was to study the effect of conservation in various cryoprotectants on the biomechanical and morphological properties of the umbilical cord (UCA) arteries.Materials and methods. The material for this work was 12 umbilical arteries, which were divided into 4 study groups: (1) native UCA – control without freezing; (2) APC frozen in 5 % dextran with the addition of dimethyl sulfoxide (DMSO) to 10 % and 7.5 % human serum albumin (HSA); (3) APC frozen in glycerin and (4) UCA frozen in propanediol. For all groups, morphological and biomechanical studies were carried out. The statistical data were processed using the GraphPad Prism 9.2.0 program. Analysis of variance was used to find significant differences.Results. Freezing with 5 % dextran, 10 % DMSO and 7.5 % human albumin did not lead to significant changes in the morphology of vascular tissue compared to control. The conserved vascular tissue retains a moderate level of type I collagen, regardless of the method of conservation. The presence of statistically significant differences between the control and frozen UCAs was shown for Young's modulus (p < 0.05; 6.9 [6.8; 7.0] for the native artery; 2.3 [2.0; 2.6] for the artery preserved with the use of dextran, DMSO and human albumin; 2.3 [1.4; 3.2] for the artery preserved in glycerin and 0.8 [0.6; 1.0] – in propanediol, respectively).Conclusion. 1) Freezing and storage of UCA at 5 % dextran, 10 % DMSO and 7.5 % HSA does not lead to a significant change in the morphology of vascular membranes and cell nuclei; 2) The preservation of type I collagen according to the results of IHC is qualitatively reduced from a conditional indicator of +2 to +1 for frozen agroindustrial complexes compared with control ones; 3) Conservation leads to a significant decrease in the modulus of elasticity of the walls of the agroindustrial complex compared with control vessels (p < 0.05).
Mobilizing Communities to Sustainably Produce Face Masks: Public Health Practice in the Time of COVID-19
Authors: Snyder Andrew M. , Weisel Heidi L. , Chatfield Sheryl L. 
Published: September 2022

Background: Face mask shortages in health care and use recommendations and requirements in a variety of com-munity and professional contexts associated with the coronavirus disease 2019 (COVID-19) pandemic in the United States created initial and ongoing demand for face masks. In March 2020, the US Centers for Disease Control and Prevention (CDC) provided guidelines for use of cotton masks for individuals in health care settings and in public. Community volun-teers provide a potential workforce to rapidly and flexibly address critical needs in emergent circumstances.
Methods: People Protecting Each-other Sustainably (PPEs) was developed to recruit and manage over 100 Northeast Ohio volunteers. People Protecting Each-other Sustainably used the social media platform Facebook to facilitate material donations, volunteer recruitment and training, and to function as an ongoing central communications hub. Leaders used an assembly line process with zero contact pick up and drop off at multiple stages of production to allow safe assembly and distribution of face masks.
Results: A total of 7 695 handmade face masks were created to distribute to local frontline responders in 10 weeks. Use of upsourced and donated materials allowed this project to reduce potential landfill waste and made a zero cost project possible. Volunteers had positive responses to the project and reported benefits from their participation.
Conclusion: This model has been successfully recreated by a smaller group in Geauga County, Ohio, with similarly successful results. Clearly this model of community mobilization has the potential to be replicated in other state of emer-gency crises and emergency response situations to produce lifesaving or necessary equipment when industry standard equipment is not readily available.
