Published: February 2023

Background:

Flow diversion (FD) is an established treatment for large or giant wide-necked unruptured intracranial aneurysms. In the past few years, the use of flow diverter devices was extended to several other “off-label” indications, including solitary or adjunctive treatment to coil embolization for direct (Barrow A type) carotid cavernous fistulas (CCFs). The use of liquid embolic agents still represents the first-line treatment for indirect CCFs. Typically, the ipsilateral inferior petrosal sinus or superior ophthalmic vein (SOV) is the preferred transvenous routes to access CCFs. In some cases, vessel tortuosity or different features make the endovascular access challenging, thus requiring different approaches and strategies. The aim of the study is to discuss rational and technical aspect in treating indirect CCFs referring to the most up-to-date literature. An alternative experience-based endovascular strategy with FD is described.

Methods:

We report the case of a 54-year-old woman diagnosed with indirect CCF and treated with flow diverter stent.

Results:

After multiple unsuccessful attempts at transarterial right SOV catheterization, a right indirect CCF fed by a single trunk at the ophthalmic origin from the internal carotid artery (ICA) was treated by ICA stand-alone FD. Blood flow was redirect and successfully reduced through the fistula, with immediately postprocedure improvement of the patient’s clinical status (ipsilateral proptosis and chemosis). Ten-months radiological follow-up showed the complete obliteration of the fistula. No adjunctive endovascular treatment was performed.

Conclusion:

FD appears a reasonable alternative stand-alone endovascular strategy also for selected difficult-to-access indirect CCFs, when all conventional routes are judged unfeasible. Further investigations will be necessary to better define and support this potential lesson-learned application.

Published: February 2023

Endurance and speed are important components in supporting the success of futsal athletes. To increase this ability, many things can be done, one of which is to provide caffeine before exercising for maximum results. This study aims to determine the effect of caffeine on the endurance and speed of futsal athletes in Mataram. The research used is the type of experiment. In this study, the instrument for measuring endurance is the bleep test, while the speed is measured using the 100-meter sprint. This study is a population study because all populations are the research sample. The entire population is used in this study because all 16 samples are national athletes in the Vamos Mataram futsal group, and the research focuses on that one elite club. Data analysis was carried out using ANOVA with the help of SPSS. Based on the results of the data analysis of the futsal athletes of Vamos FC Mataram with the administration of caffeine, the significance value for endurance was 0.000 and the significance value for speed was 0.038. Based on the results of the significance test for the two variables having a value lower than 0.05, the data stated that there was an impact caused by caffeine administration to increase endurance and speed. The research has limitations, namely only focusing on one elite futsal club, namely Vamos Mataram, but the results are expected to be able to refer to the use of caffeine in an exercise program to be able to improve endurance and speed. Further research is expected to be able to cover more than one club as well as the addition of variables.

Marrying Materials and Processes: A Unified Optimization for Adsorption Processes
Authors: Elahi Amir Mohammad , Ramezani Kimiya , Hosseinzadeh Hejazi Sayed Alireza , Rajagopalan Ashwin Kumar
Published: February 2023

The performance of an adsorption-based separation process is dictated by the choices of the adsorbent and the process configuration. In typical studies, either several materials are screened for a specific process configuration to find the best candidate, or the performance of several process configurations is evaluated for a specific material. However, it has long been suggested that to truly maximize the potential of a given material, it should be “married” to processes. Here, we have developed a modeling framework for a hybrid adsorption cycle composed of several process configurations and a unified optimization approach to select the optimal material-process combination. We have shown through several case studies that (1) one needs to employ an integrated optimization approach to maximize the potential of any material when screening for a given application; (2) one should not generalize the observations regarding the best process configuration from one material to every other material.
Control of ligand exchange rate between coordination cages by the steric bulk of the ligand and the coordinating solvent
Authors: Walker Samuel , Chant William , Tuck Kellie , Turner David
Published: February 2023

Understanding the intricacies of self-assembly and ligand exchange has wide-ranging applicability in current inorganic chemistry and in the future design and assembly of complex, functional materials incorporating metal-ligand motifs. Ligand exchange between two paddlewheel-based M4L4 cages results in the formation of a near-statistical mixture of homo- and hetero-leptic species. Steric bulk allows tuning of the lability of the ligands in the coordination cage complexes with bulkier ligands forming cages having half-lives ca. three times that of the least hindered species. Solvent plays an important role in the lability of the ligands of the coordination cages; larger solvent molecules coordinated to the exterior of the metal nodes provide a stabilizing effect, slowing the rate of ligand exchange. In some instance the final equilibrium position is slightly perturbed by the combination of steric bulk from the two ligands, suggesting that the self-assembly process are not trivial.
Fragment-Based Calculations of Enzymatic Thermochemistry Require Dielectric Boundary Conditions
Authors: Bowling Paige , Broderick Dustin , Herbert John
Published: February 2023

Quantum-chemical calculations of enzymatic thermochemistry require hundreds of atoms to obtain converged results, severely limiting the levels of theory that can be used. Fragment-based approaches offer a means to circumvent this problem, and we present calculations on enzyme models containing 500–600 atoms using the many-body expansion with three- and four-body terms. Results are compared to benchmarks in which the supramolecular enzyme–substrate complex is described at the same level of theory. When the amino acid fragments contain ionic side chains, the many-body expansion oscillates under vacuum boundary conditions, exaggerating the role of many-body effects. Rapid convergence is restored using low-dielectric boundary conditions. This implies that full-system calculations in the gas phase are inappropriate benchmarks for assessing errors introduced by fragment-based approximations. For calculations with dielectric boundary conditions, a three-body protocol with distance cutoffs retains sub-kcal/mol fidelity with respect to a supersystem calculation at the same level of theory, as does a two-body protocol when combined with a full-system correction at a low-cost level of theory. Both calculations dramatically reduce the cost of large-scale enzymatic thermochemistry, paving the way for application of high-level ab initio methods to very large systems.
Non-linear temperature dependence of nitrogen adsorption and decomposition on Fe(111) surface

Published: February 2023

The cleavage of the N2 triple bond on the Fe(111) surface is believed to be the rate limiting step of the famed Haber-Bosch ammonia catalysis. Using a combination of machine learning potentials and advanced simulation techniques, we study this important catalytic step as a function of temperature. We find that at low temperatures our results agree with the well-established picture. However, if we increase the temperature to reach operando conditions the surface undergoes a global dynamical change and the step structure of the Fe(111) surface is destroyed. The catalytic sites, traditionally associated with the Fe(111) surface appear and disappear continuously. Our simulations illuminate the danger of extrapolating low-temperature results to operando conditions and indicate that the catalytic activity can only be inferred from calculations that take dynamics fully into account. More than that, they show that it is the transition to this highly fluctuating interfacial environment that drives the catalytic process.
Identification of a Small Molecule that Binds to the PD-L1 Dimer Interface

Published: February 2023

In recent years, antibody drugs targeting PD-1/PD-L1 immune checkpoints have shown immense clinical benefits in cancer treatment. However, these drugs suffer from poor patient tolerance, large and difficult-to-control adverse reactions, insufficient oral bioavailability, and low response rates for most solid tumours, which hinder their further application. Due to the poor pharmacodynamic properties and the shallow interface of the PD-1/PD-L1 binding pocket, progress in developing small molecule PD-1/PD-L1 inhibitors that can overcome the limitations of monoclonal antibodies has been slow. Recently, many compounds have been discovered that bind to the PD-L1/PD-L1 dimer interface, providing a promising avenue for inhibiting the interaction of PD-1/PD-L1 with small molecules. Among them, biphenyl compounds that induce PD-L1 dimerization and block the interaction of PD-1 and PD-L1 have shown strong activity. In this study, we conducted virtual screening against the PD-L1 dimer interface and identified a novel biphenyl small molecule inhibitor, ZQ-4, with a unique structure. Molecular dynamics simulations were used to determine the possible binding conformations of ZQ-4 and PD-L1 dimer, and the Alanine Scanning-Interaction Entropy method was used to compare the binding free energy of ZQ-4 and BMS-200. These results provide a foundation for optimizing the hit compound and exploring novel PD-1/PD-L1 small molecule inhibitors.

War in Ukraine: A power play between Democracy and Authoritarianism
Authors: T Suresh Kumar
Published: February 2023

This article provides an analytical discussion of the crisis of democracy and the rise of authoritarianism in the context of the Russia-Ukraine War. Some of the fundamental aspects of the post-Cold War international order are addressed in this respect, including emerging powers, anti-Westernism, authoritarianism, and new threats in international relations. It is argued that the post-Cold War period brought both stability and instability to the global world order. On the one hand, the United States' victory in the ideological conflict between the East and the West led to the dominance of the Western system and its influence in the Middle East and Central Eastern European region with the call for democracy. On the other hand, the growing intervention of the US in intra-state disputes through the deployment of NATO has become a major concern to Russia and many other nations along the eastern border. This intensified anti-Western sentiment in emerging countries, with the rise of many Authoritarian governments. Many of the conflicts that the world has witnessed since the end of the Cold War are the result of such anti-Western feelings. This resulted at the beginning of a new era of war and conflict on a global scale. Russia's war in Ukraine is one of the recent examples. Russia is attempting to maintain its sphere of influence to avoid joining NATO and the West, regardless of the cost or repercussions of the war. As a result of these conflicts between great powers, several new powers emerged, resulting in a multi-polar world order. Today, it is emphasized that the ability and willingness of great powers to cooperate in addressing these dangers will determine the course of the world.
China’s (Unreal)Multilateralism and (De)Americanization of New World Order: Rhetoric Analysis of Russia’s War on Ukraine
Authors: Debashis Chakrabarti  , Amaresh Jha
Published: February 2023

Decentralized and multilateral world order is the emerging concept in the context of Russia’s war on Ukraine. The perception of de-Americanized world order is visible in the rhetoric of Russian and Chinese premiers. This study thoroughly analyses the narratives on Russian war against Ukraine primarily centered around democratization of international relations and de-Americanization of new world order. The Russia’s war on Ukraine has started re-shaping the world order largely in the direction of decoupling the America-centric bellicosity. The colonial mindset of the west in the foreign and security affairs has already been questioned by the idea of the de-westernization, but since within the west also there is a divide on accepting American belligerence there is a need to thinking the new world order as de-Americanization. The American direction and dominance in the matters of international peace and security has largely been parochial. But in the context of Russia-Ukraine war now the post-western and extra-western narratives have put forth the validity and dominance of the ideas of non-western countries of the world. The rejection of western ideas and technologies is no longer a new phenomenon. Many countries in the world have developed their own social space for communicating the indigenous ideas without getting influenced by western or American narratives.

Structural Analysis of Voting Intention of Indian Electors in the Framework of Theory of Planned Behaviour
Authors: Debashis Chakrabarti  , Amaresh Jha
Published: February 2023

Is voting a planned behaviour? If so, does the theory of planned behaviour apply to voting intention? This study uses structural equation modelling as a method to analyse the responses of voters to re-test the theory of planned behaviour in the context of Indian elections. The researchers assume that attitude, subjective norms and perceived behavioural control of electors is positively related to voting intention. The participants in the survey are the Indian electors who exercised their right to elect during the 2014 & 2019 Loksabha (Parliamentary) elections in India. The findings provide ample evidence to support that voting intention is to large extent a planned behaviour and is shaped largely by attitude, and not much by subjective norms and perceived behavioural control of the electors.
Public Opinion Research on the Politics and Objectives of the Special Military Operation of the Russian Federation in Ukraine
Authors: Romanovich Nelli Alexandrovna
Published: February 2023

The special military operation of the Russian Federation in Ukraine has split the world into two opposing camps: supporters and opponents. In this regard, the opinion of the Russians themselves about the causes and goals of the military operation that has begun is being updated. The results of the all-Russian survey presented in the article reveal the ideas of Russians about the reasons and goals of the military operation, and also clarify the degree of its support from the population. The level of loyalty to the President of the Russian Federation after the outbreak of hostilities is considered, and a hypothesis is put forward that the level of support for the special operation may increase as it is successfully implemented.
Examining Early Elementary Computer Science Identity Repertoires within a Curriculum: Implications for Epistemologically Pluralistic Identities
Authors: Richard Eleanor , Kayumova Shakhnoza
Published: February 2023

As computer science (CS) enters an increasing number of elementary classrooms, researchers must investigate the representations of what kinds of people are presented as doing computer science within CS curricula. In this paper, we explore a widely used, freely accessible, web-based, early elementary CS curriculum to examine the kinds of identity repertoires (behaviors, actions, skills, and socioemotional norms) that are promoted as representative of being/becoming a CS person. More specifically, we draw on identity studies and employ critical discourse analysis to examine how the kinds of norms and repertoires of CS practice made available in the curricular materials might construct a particular account of experiences as representative of being and enacting identities in computer science, and in doing so, produce certain accounts of who a CS person is. Our analysis shows that the curricular materials may construct an identity of a computer science person as someone who is able to solve a puzzle correctly, persist through challenges, connect to their feelings, and work with peers. While this curriculum promotes skills, norms, and repertoires of CS practice aligned with state standards, our findings suggest that it does not appear to present varied and flexible notions of what it means to engage in or be/become a CS person.
THE CATEGORY OF SENSE AND MEANING IN PSYCHOLOGICAL DISCOURSE
Authors: M.V. Godunov , E.A. Portnov , Yu.A. Karnaukh , O.Yu. Tuzova
Published: February 2023

In the field of human sciences the category of sensing does not coincide with the category of meaning. In the field of psychology there is also no unified definition of these categories. However, it is the meaning approach to the regulation of life activity that is the most effective in terms of modeling human behavior. Since meaning is broader than sence, it is the meaning interpretation that forms the basis of the psychology of understanding. Meanings express the subjective importance of objectively represented meanings of what happens in the world around us. In existential psychology, it is possible to describe the uniqueness of human existence on the basis of meaning representations. Meanings reflect the uniqueness of personal experience and the depth of a person's feelings experienced during his or her life. At the same time, the meanings and direction of a person's individual behavioral acts should be considered from the context of both the entire lived life and future life meanings. From cultural and historical positions, meaning is a psycholinguistic category, which acquires personal content in relation to meaning. Meanings reflect correlation of motives and goals of life activity. Meanings reflect not only intellectual content, but also show the emotional content of the experienced state. In personal development, meaning reflects the nature of interactions between individual perceptions of life and societal expectations about one's place in this life. Meaning sets the individual to perform activities in a certain way. This sets the stability and purposefulness of personal development. Personal self-determination in choosing the direction of professional development has a value-semantic nature, and also depends on motivation. The system of personal meanings has a complex manifestation and multilevel hierarchical structure. Meaning should be considered as an interdisciplinary construct that reflects the understanding of subjective meaning in psychology, philosophy, and linguistics. Meaning reflects the relationship between the subject and the object. This relation expresses the place of the object in the life of the subject, and this object is highlighted in the image of the subject's world. Thanks to this regulation of behavior of the subject in relation to the given object is carried out.

This mixed methods study examines the impact teacher professional development has on the levels of concern of nine Ugandan teachers as they begin to use computers in their school environment. These teachers completed the Stages of Concern Questionnaire before and immediately following training on the basics of how to use a computer for educational purposes. Additionally, qualitative data in the form of interviews and written responses were collected and analyzed to look at what aspects of the training were considered to be most beneficial to the participants. The results of the quantitative data suggest the teachers’ level of concern in three of the seven levels decreased after training was provided. The results of the qualitative data show the teachers would like more time to experiment with the new information they learned through the professional development and want input into what they will be learning.

This study investigated the effects of 28 GHz and 73 GHz frequencies, the number of transmitting and receiving antennas, and LOS/NLOS parameters on 5G channel capacity using the NYUSIM channel simulator. As a result of the analysis, changing from a 2x2 to a 64x64 antenna structure for 28 GHz increased capacity by 29.78 times for LOS and 26.91 times for NLOS. When changing the MIMO configuration from 2x2 to 64x64 at 73 GHz, the channel capacity rises 36.88 times for LOS and 29.00 times for NLOS. With a 64x64 antenna structure, the channel capacity for 28 GHz and LOS is 8.81 times higher than for 73 GHz, and it is 12.56 times higher for NLOS. For the 28 GHz 64x64 structure and LOS condition, the channel capacity is 215.69 times higher than the NLOS condition, while this value is 307.7 times for 73 GHz.

In this experimental study, the Robust Output Feedback controller (ROF) is designed based on the H_∞ theory and implemented to the level control of the coupled tank system. As many chemical processes have complicated and nonlinear characteristics, this robust methodology is proposed to tackle them. Hence, the vertical coupled tank system is selected as one of the popular case study systems to simulate the large-scale chemical processes to illustrate the effectiveness of the proposed ROF controller. Linear Matrix Inequalities (LMIs) methodology is selected as the main mathematical method of the design procedure. To illustrate the best performance and robustness of the ROF controller, the simulation and experimental results are compared to the Feedforward Proportional Integrator, one of the most common controllers in the industries. Two different liquid level control scenarios are considered in this comparison and the obtained results show the expected performance of the ROF controller guaranteeing the design objectives.

The enactment of job creation law considers as the government effort to develop the ecosystems of competitiveness and investment in Indonesia. Even though there are many rejections, the government are optimistic that this provision could provide significant improvement for various sectors such as the sector on manpower. The research aim is to understand the concept changes and outsourcing requirements based on the job creation Act. The method of this research using legal doctrine or normative juridical method by conducting references through secondary data studies. In Legal research, secondary data includes primary legal materials, secondary legal materials, and tertiary legal materials. The research result illustrates that the protection of workers/labor, their wages and welfare, the working conditions also if disputes arise will be carried out by virtue of the regulations and are the responsibility of outsourcing company. The obstacles may emerge such as the absence of obligations under the outsourcing contract. Therefore, the legal certainty is not existed to protect the workers, since the legal protection for workers are according to the agreement.

Resumo. O processo de galvanização por imersão à quente é amplamente utilizado pela
indústria automobilística a fim de se obter um recobrimento de zinco (????) como proteção
anticorrosiva para chapas de aço. A fim de se evitar a formação de fases deletérias na camada
zincada, alumínio (????) é adicionado ao banho de zinco. Forma-se então uma camada dita
inibidora composta pela fase que fica situada entre o substrato e o recobrimento e que
impede a formação das fases indesejáveis. Entretanto, se por algum motivo a fase contendo
alumínio se situar fora da região limítrofe entre substrato/revestimento, tem-se o que é
chamado Dross, que pode ser considerado um defeito caso fique aparente e visível na
superfície revestida da chapa. Este trabalho utilizou técnicas de caracterização por
Microscopia Eletrônica de Varredura (MEV), microanálise química por Energy Dispersive
Spectroscopy (EDS) e Análise e Processamento Digital de Imagens (PDI) por segmentação
colorida para caracterizar a camada inibidora e a presença do Dross em chapa de aço
galvanizada a quente. Considerando os parâmetros de galvanização utilizados o revestimento
apresentou camada inibidora com 1,35 ± 0,19 µm de espessura, com morfologia descontínua e
representando 1,39% do revestimento. Foram verificadas presenças isoladas do Dross.

Published: February 2023

The study is relevant to the current global trends of business environment turbulence and marketing transformation under the influence of the war in Ukraine. The purpose of the article is to identify the reasons for the transformation of marketing under the influence of the war in Ukraine related to various aspects of the problems of marketing activities of business companies that lead to this, and to develop recommendations for improving marketing policy and improving the prospects for business profitability. The novelty of the study lies in the creation of a theoretical model of marketing transformation in the context of turbulence in the business environment. The object of the scientific research is determined as marketing activities of Ukrainian business representatives during the war. The research methodology includes such methods: comparative analysis, critical analysis, descriptive analysis, statistical analysis. The study is based on the results of a sociological survey of business representatives in Ukraine. The study's limitations are that the data collection period covers September-October 2022 during the war in Ukraine. The obtained results confirmed the authors’ hypothesis H1 that Ukrainian businesses use the limited marketing toolkit in times of war that worsens perspectives of marketing transformation in the direction of income growth; H2 – relocation has not really become the driver of marketing transformation in the war-time period as majority of businesses has not realized it in general; H3 – one more problematic zone of marketing activity in the war-time period is the ability of work with clients, which is not well used by the majority of surveyed Ukrainian businesses; and Н4 – the main problem for business not only the war itself, but the absence of effective marketing strategy in general. The practical value of the research for the young scientists’ community is in the use of the model of marketing transformation and the practical research results in changing the marketing identity of business entities, which gives the opportunity to improve marketing strategy and the company’s profitability. The possible directions of the research development are studying of the correlations of marketing with other elements of business activity and their impact on post-war business recovery.

Objective This study explored the psychometric properties of the Chinese version of the Stress and Anxiety to Viral Epidemics-6 Items (SAVE-6) scale for cold chain practitioners exposed to moderate-to-high risk of infection.Methods A total of 233 cold chain practitioners participated in an anonymous online survey, conducted from October to November 2021. The questionnaire comprised participant demographic characteristics, the Chinese version of SAVE-6, the Generalized Anxiety Disorders-7 (GAD-7), and the Patient Health Questionnaire-9 (PHQ-9) scales.Results Based on the results of the parallel analysis, the single-structure model of the Chinese version of SAVE-6 was adopted. The scale showed satisfactory internal consistency (Cronbach’s alpha=0.930) and good convergent validity based on Spearman’s correlation coefficient with the GAD-7 (rho=0.616, p<0.001) and PHQ-9 (rho=0.540, p<0.001) scale scores. The optimal cutoff score for Chinese Stress and Anxiety to Viral Epidemics-9 Items was identified as ≥12 (area under the curve=0.797, Sensitivity=0.76, Specificity=0.66) for cold chain practitioners.Conclusion The Chinese version of the SAVE-6 scale has good psychometric properties and can be applied as a reliable and valid rating scale to assess the anxiety response of cold chain practitioners in the post-pandemic era.
