Estimación de resiliencia ecológica en la laguna Las Peonías (Venezuela) mediante análisis integrado (GIS-LiDAR)
Authors: Marin Julio , Moreno Oswaldo , Bastidas Eglimar , Corona Ángel , Fernández Andreina
Published: December 2023

La resiliencia ecológica refleja la capacidad de un ecosistema para mantener sus condiciones funcionales y estructurales ante la acción de perturbaciones externas, cuyos límites son dependientes de las características específicas y de la velocidad de recuperación. En este trabajo se estimó la resiliencia ecológica de la laguna Las Peonías (Zulia, Venezuela) entre 2011 y 2019, mediante un análisis integrado GIS-LiDAR (por su siglas en inglés, Geographic Information System ‒ Light Detection and Ranging), con la finalidad de conocer su capacidad para absorber los impactos de las actividades antrópicas y orientar la gestión ambiental futura de este cuerpo de agua. Para ello, se determinaron las zonas de actividad antrópica y se calcularon los indicadores de transformación del terreno, de impactos antrópicos y los derivados de la transformación. Los resultados exhibieron un índice de resiliencia ecológica entre <0.01 (2013) y 0.08 (2011), mientras que la regeneración costera se ubicó entre 0.46 (2013) y 75.37 (2011); indicando que la laguna se encuentra en un constante proceso regenerativo, con una capacidad muy pequeña de soportar impactos antrópicos continuos sin sufrir perturbaciones en su equilibrio, lo cual se traduce en un estado de riesgo ambiental elevado debido al desarrollo de un proceso de eutrofización activo y en nivel avanzado.

Authors: Mahmood Ari M. , Ibrahem Mohammed A.
Published: December 2023

Thin films comprised of laminated 2D nanomaterials have garnered considerable attention and hold significant promise across a multitude of applications, driven by their exceptional and distinct attributes. This study presents an innovative approach for fabricating thin films on glass substrates through the utilization of 2D multilayer liquid nanomaterials via a sputtering technique. These nanomaterials, encompassing graphene, MoS2, and h-BN, were synthesized employing a common household blender, followed by dispersion in a range of solvents, including acetone, ethylene glycol, and deionized water. In-depth characterization of the resultant thin films was undertaken, employing a comprehensive suite of microscopic and spectroscopic analytical methodologies. The outcomes of these characterizations underscore the profound influence of both the selected bulk material and the choice of solvent on the structural and morphological properties of the thin films. Impressively, the prepared thin films exhibit superlative adhesion and uniformity, manifesting smooth surfaces and a remarkable degree of crystallinity. Through the judicious selection of diverse bulk materials and solvents, this study effectively demonstrates the unparalleled versatility and adaptability of the sputtering method in producing thin films with a wide spectrum of tailored properties. This research not only advances our understanding of thin film formation but also underscores the immense potential of 2D nanomaterial-based films in diverse technological applications.

Authors: Васильев С.А. , Долбежкин В.А. , Егутия Ш.А.
Published: December 2023

В статье рассматривается риск концентрации, возникающий при аутсорсинге финансовых функций. Авторы рассматривают возможность сегментирования функций и бизнес-процессов банка в плоскости пары параметров, что может быть использовано при оценке значимости рисков передачи функций на аутсорсинг. Операционные риски «концентрированного» аутсорсинга обуславливают ряд негативных экономических факторов для банков, рассмотренных в статье. Высокотехнологичные исполнители финансовых функций не могут быть многочисленны, и это определяет неизбежность риска их концентрации, который является объектом исследования. Авторы предприняли попытку сопоставить численные параметры современной инфраструктуры банковского сектора в части, связанной с аутсорсингом финансовых функций банков, а также обосновать рост значимости рассматриваемого риска.

We consider the risk of concentration emerging from the outsourcing of financial functions. We consider the possibility of segmenting the functions and business processes of the bank as far as a couple of parameters are concerned, which could be applied in assessing the risks of outsourcing functions. The operational risks of "concentrated" outsourcing stipulate a range of negative economic factors for the banks. High-tech performers of financial functions cannot be numerous, which determines the inevitability of the risk of their concentration. We make an attempt to compare numerical parameters of the modern infrastructure of the banking sector regarding the outsourcing of financial functions of banks and to substantiate the increasing significance of the risk in question.
INNOVATIVENESS AMONG LEGAL AND DOCTRINAL SIGNS OF ENTREPRENEURIAL ACTIVITY
Authors: Савенко Н.Е.
Published: December 2023

В статье на основе доктрины и законодательства проанализирован признак инновационности предпринимательской деятельности. Утверждается, что инновационность в предпринимательстве исторически обусловлена развитием технического прогресса и имеет экономическую сущность. Акцентировано внимание на том, что инновационность не отражена в числе легальных признаков предпринимательской деятельности (ст. 2 Гражданского кодекса РФ), поскольку она является межотраслевой категорией, выходящей за цивилистические рамки. Проведено соотношение категорий «инновационная деятельность» и «предпринимательская деятельность». Сделан вывод о том, что на современном этапе экономического развития инновации становятся неотъемлемой частью предпринимательской деятельности.

On the basis of doctrine and legislation the article analyzes the sign of innovativeness of entrepreneurial activity. It is stated that innovativeness in entrepreneurship has been historically preconditioned by the development of technological progress and has an economic essence. It is emphasized that innovativeness is not reflected among legal signs of entrepreneurial activity (article 2 of the Civil Code of the Russian Federation), as it is an intersectoral category that goes beyond the civilistic framework. The correlation between the categories of "innovative activity" and "entrepreneurial activity" was carried out. It is concluded that at the present stage of economic development innovation is becoming an integral part of entrepreneurial activity.

WEALTH, VALUE AND CAPITAL IN WORKS OF CLASSICAL SCHOOL REPRESENTATIVES
Authors: Сорокин А.И.
Published: December 2023

В статье рассмотрена проблема поиска источника богатства и ценности в общественном производстве, а также связанная с ними роль капитала, нашедшая свое отражение в трудах представителей экономической науки в XVII–XIX вв. Данный период известен как господство взглядов представителей классической школы. Необходимо заметить, что понятие «классическая школа» не являет собой что-то монолитное, пронизанное какой-то единой идеей или одним методологическим основанием. Данный период становления экономической науки характеризуется как замечательными достижениями, и поныне входящими в арсенал базовых знаний по экономике, так и глубокими заблуждениями, повлекшими за собой грандиозные сдвиги в общественной жизни некоторых стран. В статье предпринимается попытка проследить взгляды видных представителей той эпохи на трактовку факторов, определяющих общественное богатство. Акцент делается на капитале как на важнейшем факторе этого богатства. Оказалось, что капитал – это очень сложное явление, трудно поддающееся линейному определению. Можно сказать, что достижения классической школы явили собой только самое начало процесса поиска адекватной трактовке этого понятия, на которое опирались следующие поколения экономистов в своих исследований проблемы.

The article considers the problem of finding a source of wealth and value in social production, as well as the related role of capital reflected in the works of the representatives of economic science in the XVII – XIX centuries. This period is known as the dominance of the views of the classical school representatives. It should be noted that the concept of "classical school" is not something monolithic, permeated with a single idea or one methodological basis. The period in question is characterized by outstanding achievements still making up the basics of economics and considerable delusions resulting in dramatic changes in the social life of certain countries. The article attempts to trace the views of prominent representatives of that era on understanding the factors determining social wealth. The focus is on capital as the key factor of the wealth. We make a conclusion that capital is a sophisticated phenomenon difficult to define linearly; the achievements of the classical school were only the very beginning of the process of searching for an adequate interpretation of this concept, for the next generations of economists to rely on.

Hydroxyl-Diazomethylation of Alkenes via Photoredox Catalysis
Authors: Zeng Ying , Zheng Xiaochan , Chen Shaoyong , Luo Zhongfeng , Xie Haisheng , Liu Junshan , Jiang Huanfeng , Zeng Wei
Published: December 2023

α-Diazoesters belong to significantly important carbenoid precursors in synthetic chemistry, diazomethylation-based difunctionalization of alkenes is highly valuable but remain nontrivial. Herein, we reported a general and modular approach for the direct 1,2-hydroxyl-diazomethylation of alkenes through visible-light photoredox catalysis. This process exploits photocatalyzed strategy to convert alkenes to γ-hydroxyl-α-diazoesters using α-diazo iodonium salts as carbyne precursors, featuring wide substrate tolerance and broad late-stage diversiﬁcations. Mechanistic studies suggest that the formation of γ-carbocation-tethered α-diazoesters plays a crucial role in trapping H2O to allow for this transformation.
Molecular Beam Scattering of Ammonia from a Dodecane Flat Liquid Jet
Authors: Saric Steven , Yang Walt , Neumark Daniel M.
Published: December 2023

The evaporation and scattering of ND3 from a dodecane flat liquid jet are investigated and compared to previous molecular beam scattering studies from liquid surfaces. Evaporation is well-described by a Maxwell–Boltzmann flux distribution with a cosθ angular distribution at the liquid temperature. Scattering experiments at Ei = 28.8 kJ mol−1 over a range of deflection angles show evidence for impulsive scattering and thermal desorption. At a deflection angle of 90°, the thermal desorption fraction is 0.54, which is ~4 % higher than other molecules previously scattered from dodecane and consistent with work performed on NH3 scattering from a squalane wetted wheel. ND3 scattering from dodecane results in super-specular scattering, as seen in previous experiments on dodecane. The impulsive scattering channel is fitted to a “soft-sphere” model, yielding an effective surface mass of 55 amu and an internal excitation of 5.08 kJ mol−1. Overall, impulsively scattered ND3 behaves similarly to other small molecules scattered from dodecane.
Can Supply Shocks Be Inflationary with a Flat Phillips Curve?
Authors: L'Huillier Jean-Paul , Phelan Gregory
Published: December 2023

Not in standard models. With conventional pricing frictions, imposing a flat Phillips curve also imposes a price level that is rigid with respect to supply shocks. In the New Keynesian model, price markup shocks need to be several orders of magnitude bigger than other shocks in order to fit the data, leading to unreasonable assessments of the magnitude of the increase in costs during inflationary episodes. To account for the facts, we propose a strategic microfoundation of shock-dependent price stickiness: prices are sticky with respect to demand shocks but flexible with respect to supply shocks. This friction is demand-intrinsic, in line with narrative accounts for the imperfect adjustment of prices. Firms can credibly justify a price increase due to a rise in costs, whereas it is harder to do so when demand increases. Inflation from supply shocks is efficient and does not justify a monetary policy response.

A novel multi-viewpoints based cosine similarity visual technique for an effective assessment of clustering tendency
Authors: Rajasekhar Pinisetty , Ravindranath Vandrangi
Published: December 2023

Data clustering is an unsupervised technique that can be used to partition the data into groups based on the similarities of the retrieved objects using different distance metrics like Euclidean, cosine, etc. In contrast to Euclidean, the cosine computes the object's similarity by considering both the magnitude and direction of the data vectors. As a result, it performed far better than a standard Euclidean distance metric in applications involving real-time data clustering. The initial k-value (clustering tendency) is required by top clustering techniques like k-means and hierarchical approaches to determine the clusters' quality. Users with knowledge can assign the k-value. However, sometimes the right k-value in such algorithms may need to be assigned. After a thorough review of the work, it was discovered that the visual technique known as visual assessment of (cluster) tendency (VAT) effectively addresses the clustering tendency issue. It uses the Euclidean metric to find the similarity features in its algorithm. Another enhanced visual technique, cosinebased VAT (cVAT), outperformed the VAT for text data and speech clustering applications. However, the similarity features are extracted about a single viewpoint in cVAT. This paper develops the multi-viewpoints-based cosine similarity measure (MVPCSM) for a more informative assessment. Instead of using a single reference point like a typical cosine measure, the MVPCSM generates precise similarity characteristics using several views. The performance of the existing and proposed technique (MVPCSM-VAT) is evaluated using clustering accuracy (CA) and normalized mutual information (NMI). It has been demonstrated that the proposed MVPCSM-VAT is 15-25% more efficient than VAT and cVAT in terms of the parameters of CA and NMI.

Queuing models consisting of servers which may not work with full efficiency are modelled with the help of fractional differential equations. Such problems with partial activity of the server are designed with the help of differential-difference equations involving fractional derivatives whose solutions are expressed in terms of Mittag-Leffler function. In this paper, we propose an alternative approach which gives a transient solution of fractional M/M/1 queue in matrix form. The results obtained by this new approach are justified by comparing them with solutions of classical queue which are available in the literature. Efficacy of the model can be assessed by computing its state probabilities and also measures such as expected number of customers in the system etc. Also, the variations in these measures with respect to partial activity of the server have been presented graphically and numerically. Further, a mathematical procedure to find optimal efficiency of the server has been discussed.

The aim of our work was to estimate the plasma amino acid (AA) spectrum peculiarities in coronary artery disease (CAD) patients with atrial fibrillation (AF) and to check their connections with cardiometabolic risk factors and gu, microbiota metabolites. 300 patients were divided into three groups: first – 149 patients with CAD but without arrhythmias, second – 123 patients with CAD and AF paroxysm and control group – 28 patients without CAD and arrhythmias. Plasma AA level was detected by ion exchange liquid column chro­matography method. The plasma AA spectrum changes in CAD patients with AF paroxysm were investigated: some plasma AA (glutamate, glutamine, glycine, alanine, valine, tyrosine) and their combinations (Isoleucine+Leucine/Valine, Glycine+Serine, Glycine/Methionine, Phenylalanine/Tyrosine, Glutamine/Glutamate) had significant changes in second group patients and had correlations with cardiometabolic risk factors (glycine, valine, arginine, glutamate, isoleucine, alanine, methionine (p<0.05)). Plasma AA combinations were revealed, the lattert could be used as an early marker of AF paroxysm in CAD patients by the results of ROC analysis: 2.44 * Isoleucine – Glycine; area under ROC-curve 0.8122 and 3.16 * Phenylalanine – Glycine, area under ROC-curve 0.8061. Plasma AA spectrum evaluation could be a new promising metabolic marker for AF paroxysm in CAD patients. Altered AA levels point to the depth of pathogenetic changes during AF paroxysm formation: disorders of AA metabolism with branched chain (isoleucine, leucine, valine), aromatic AA (phenylalanine, tyrosine), glutamine/glutamate, glycine/serine and glyci­ne/methionine metabolism. A strong reliable connection between plasma AA spectrum and gut microbiota metabolites (trimethylamine, trimethylamine-N-oxide, total amount of fecal short chain fatty acids) was detected.

One of the ischemic stroke prevention methods is reconstructive surgery on the carotid arteries, during which there is a risk of ischemia-reperfusion phenomenon. Nevertheless, there is still a high risk of stroke at all stages of the surgery, which equally depends on the atherosclerotic plaque structure and on the technique and tactics of surgery. The aim of this study was to investigate the dynamics of redox homeostasis and nitric oxide production in the blood taken from the internal jugular vein in patients with carotid arteries pathology against the episode of cerebral blood flow restriction during carotid surgery. This prospective cohort study involved 56 patients which required carotid reconstructive surgery. The markers dynamics of oxygen metabolism, redox homeostasis and nitric oxide production in blood from the internal jugular vein on the side of surgery were studied. It was found that the activity of free radical processes is proportional to the level of jugular hypoxemia. Bidirectional dynamics of lactate concentration during intraoperative transient cerebral ischemia was revealed. In some patients, lactate production activates with an increase in free radical processes activity in proportion to the intensification of nitric oxide synthesis against a decrease in peroxynitrite production and activation of molecular compensatory mechanisms increasing concentrations of L-arginine and reduced glutathione. In others, the extraction of oxygen from the blood increases without lactate production, activation of nitric oxide synthesis and development of oxidative stress. This indicates good adaptive reserves against acute restriction of cerebral blood flow.

Recently, molecular genetic studies have become widespread, and demonstrated the importance of DNA and histone methylation processes in the epigenetic regulation of gene expression. The aim of this study was to detect the association of polymorphisms of the folate cycle enzyme gene methylenetetrahydrofolate reductase (MTHGFR) with the degree of cognitive and affective disorders and the serum level of homocysteine and folic acid in 41 post-covid patients. Hematological and laboratory indices, serum concentration of C-reactive protein, D-dimer, homocysteine and folic acid were determined. MTHGFR polymorphisms for C677T and A1298C mutations were determined by polymerase chain reaction in real time. According to the MTHGFR C677T genotype variant, the examined patients were divided into 3 groups: 1) 21 persons (male/female 10/11) with homozygous CC genotype; 2) 17 ones (male/female 12/5) with heterozygous CT genotype; 3) 3 persons with a recessive homozygous TT genotype (all men). Six months after the end of the acute phase of the coronavirus disease, patients were surveyed using questionnaires to assess the psycho-emotional state: cognitive function, anxiety and depression. No significant difference was found in the average scores of cognitive function, anxiety and depression in patients of group 1 and 2. Individuals of the group 1 C677C, who had an additional recessive homozygous C1298C mutation (group 1a, n=6), were characterized by an elevated level of homocysteine, which showed a high negative correlation with serum folate (r= -0.95). A small group of individuals with the recessive homozygous T677T genotype (group 3, all men) was distinguished by an older age, the presence of cardiovascular diseases, type 2 diabetes (2 cases out of 3), more severe manifestations of COVID-19, which forces us to pay attention to potentially increased risk of complications in such patients and requires further investigation. Correlation relationships between assessments of cognitive function, anxiety, depression and serum levels of homocysteine and folate in patients with different genotypes of MTHGFR C677T were recorded. Therefore, the use of a molecular genetic approach made it possible to pay attention to the possible predisposition to hyperhomocysteinemia in individuals who have a folic acid deficiency, and different combination of alleles of the MTHGFR gene C677T and A1298C.

SARS-CoV-2 virus, which causes coronavirus disease 2019 (COVID-19), apart from respiratory manifestations, is able to directly affect the cardiovascular system. Therefore, different from general population target values of blood pressure might be beneficial for the patients with COVID-19. The aim of this study was to investigate whether conventional blood pressure control was associated with the severity of COVID-19. From 260 patients that were hospitalised to the unit subdivision of stable patients of COVID-center between March, 2020, and December, 2020, 163 patients with confirmed infection with SARS-CoV-2 virus and hypertension were selected. The patients were distributed by hypertension control: blood pressure <140/90 mmHg (n=94) and blood pressure ≥140/90 mmHg (n=69). Routine instrumental and laboratory investigations were registered and analysed. The patients were diagnosed and treated according to national and European guidelines. The information about the control of blood pressure was taken from the patients’ medical records. The group of patients with controlled hypertension had higher prevalence of females (p=0.03), 10 years higher median of age (p<0.01) and lower frequency of obesity (p=0.04). The patients with controlled hypertension had lower median of pulmonary injury (p=0.04) and lower frequency of SpO2<92% (p=0.02). Glomerular filtration rate <60 ml/min and proteinuria were detected significantly more frequently in the patients with controlled hypertension (p=0.02). In the presented study blood pressure below 140/90 mmHg before the admission to the hospital was associated with a lower degree of pulmonary injury but with the higher frequency of nephropathy signs. Urine test and blood creatinine monitoring might be beneficial for the patients with COVID-19 and hypertension.
