Аnalysis of marginalism. Part 1
Authors: Wu Jie
Published: July 2023

В последние годы, китайские и российские ученые, сохраняя в качестве основы традиционную теорию стоимости, — трудовую теории стоимости и теорию прибавочной стоимости, а также гипотезу Джевонса, Теслы и Фоули — использовали математическую парадигму теоретической механики для создания системы математических моделей экономики, которую назвали новой теорией стоимости. Совместимая с традиционной теорией, новая теория стоимости выдвигает идею о том, что потребляемая в процессе производства рабочая сила определяет стоимость товара, а сила притяжения рабочей силы определяет оценку ее самой. В тоже время оценка стоимости зависит от гравитационной силы, созданной путем усовершенствования навыков работников. В процессе производства постоянный и переменный виды капитала и потенциальная энергия стоимости, переходящая одна в другую, согласно теореме преобразования стоимости, играет ведущую роль в создании стоимости и прибавочной стоимости. Кроме того, закон убывающей предельной полезности не является аксиомой, а специальным экономическим законом при дисбалансе спроса и предложения. Эти теоретические положения имеют большое значение, поскольку превращают традиционную теорию стоимости в самодостаточную логическую систему в виде новой теории стоимости, которая вобрала рациональные элементы как из классической экономики, основанной на трудовой теории стоимости, и теории прибавочной стоимости, так и из неоклассической экономики с ее законом убывающей предельной полезности. В первой части статьи мы обращаемся к этой проблематике, исследуя происхождение закона убывающей предельной полезности.
Optimization of structural dynamics of the economy in the framework of the “input-output” methodology
Authors: Toroptsev Evgeny
Published: July 2023

The dynamic input-output balance model in the form of a system of differential equations, being digitized by the already published author's methodology, allows solving a wide range of problems of static structural stability of economic systems. Structural dynamics can be optimized by including any variable parameters in the vector and the limit of all model elements. In this paper, inter-sectoral inertias are chosen, and a method is proposed that uses a vector of parameters of an arbitrary (allowed by the model itself) length at the step of the search process. This distinguishes the proposed method from existing ones, making it unique. The uniqueness specified here lies in the removal of the so-called “curse of dimensionality” inherent in the classical optimization problems (numerical search problems) using methods from the coordinate-wise descent to the rich Newtonian-type tools. In this sense, the method is a competitor to machine learning-based optimization of artificial neural networks. At the same time, it does not matter how exactly the task is formalized: it should highlight the target indicators and the vector of variable parameters. It is possible to define and solve many optimization problems by changing the content of the vector of variable parameters according to the corresponding plan of the computational experiment. The paper presents only one example and one optimization stage. The limiting and functional conditions for the operation of the method preserve a linear relationship between the desired increments of the fundamental parts of the eigenvalues of the model state matrix and their sensitivities to control parameters. Such “small” optimization steps are separate and independent problems, the numerical solution of which can be repeated.
Computer testing of a non-parametric partial equilibrium model prototype
Authors: Svetlov Nikolai
Published: July 2023

On the basis of non-parametric formulations of the production program problem (previously known) and the consumer choice problem (new), a computable partial equilibrium model with a non-parametric representation of both supply and demand is proposed. In this model the problems of the producer and the consumer are represented by simultaneous inequalities of the dual problems pair. This converts the problem of finding an equilibrium to minimizing the differences between objective functions in each pair, summarized over producers and consumers. Such a problem, however, may have multiple local optima. Computer tests on artificial data sets confirmed that inserting such “technical” constraints into a computable model, that are always valid in an equilibrium, can effectively direct the search for a solution using the CONOPT4 procedure to the global optimum (to which the sought equilibrium corresponds). In all 36 tests carried out, equilibrium solutions were found on the first try. The result obtained is of significant importance for the creation of tools used at the sectoral level in managing the unstable economic dynamics that are characteristic of periods of change in systems of dominant technologies. Such tools will make better use of the information in the original empirical data.

Edge detection techniques using nonlinear diffusion-based models
Authors: Barbu Tudor
Published: July 2023

An overview of the edge detection techniques based on partial differential equations (PDE) is presented in this work. Nonlinear anisotropic diffusion-based boundary extraction approaches, like the influential Perona- Malik model and some improved variants of it, are described first. Anisotropic diffusion-based detection schemes using the mean curvature motion and nonlinear PDE-based approaches combining anisotropic diffusion to the bilateral filter are then discussed here. Some nonlinear reaction-diffusion-based edge detection methods are described next. Variational edge detection solutions using the total variation (TV) regularization or combining the anisotropic diffusion to the TV-based models are then presented. Directional diffusion-based image edge extraction algorithms are also discussed. Our own contributions in this computer vision domain are finally described.

Background:

The role of blood uric acid as a biomarker in symptomatic motor PD has been increasingly established in the literature.

Objective:

Our present study assessed the role of serum uric acid as a putative biomarker in a prodromal PD cohort [REM Sleep Behavior disorder (RBD) and Hyposmia] followed longitudinally.

Methods:

Longitudinal 5-year serum uric acid measurement data of 39 RBD patients and 26 Hyposmia patients with an abnormal DATSCAN imaging were downloaded from the Parkinson’s Progression Markers Initiative database. These cohorts were compared with 423 de novo PD patients and 196 healthy controls enrolled in the same study.

Results:

After adjusting for age, sex, body mass index, and concomitant disorders (hypertension/gout), baseline and longitudinal serum uric acid levels were higher in the RBD subgroup as compared to the established PD cohort ( p = 0.004 and p = 0.001). (Baseline RBD 6.07±1.6 vs. Baseline PD 5.35±1.3 mg/dL and Year-5 RBD 5.7±1.3 vs. Year-5 PD 5.26±1.33). This was also true for longitudinal measurements in the Hyposmic subgroup ( p = 0.008) (Baseline Hyposmic 5.7±1.6 vs. PD 5.35±1.3 mg/dL and Year-5 Hyposmic 5.58±1.6 vs. PD 5.26±1.33).

Conclusion:

Our results indicate that serum uric acid levels are higher in prodromal PD subjects with ongoing dopaminergic degeneration compared to those with manifest PD. These data indicate that the well-established decrease in the levels of serum uric acid occurs with the transition from prodromal to clinical PD. Whether the higher levels of serum uric acid observed in prodromal PD may provide protection against conversion to full-blown clinical PD will require further study.
Problems of Khoomei's Continuity in Tuva
Authors:   International Academy ", Kyrgyz K.A. ,   Khoomei"
Published: July 2023

The article considers a set of factors that influenced the current development of throat singing in Tuva. In the course of evolution, musical improvisation of onomatopoeia to nature acquired an independent form and was reflected in the original and unique in its style art of Khoomei. Currently, there is a continuity of the performance of the Tuvan Khoomei, so the heritage of older generations continues to play an important role in folk traditional culture. The relevance of the research lies in the need for a comprehensive analysis of the problems of continuity in view of preserving and strengthening the traditions of the performing art of Tuvan throat singing, and assessing the contribution of Khoomeizhi to the formation and development of the musical culture of Tuva. The article reveals the mechanism and nature of the transferring of knowledge about Khoomei in Tuva. The results of the study are presented in the form of conclusions regarding the dynamics of the spread of the Tuvan Khoomei and measures to preserve the Tuvan intangible cultural heritage through the Tuvan Khoomei development model.

Published: July 2023

Artificial intelligence (AI) has made significant strides in recent years toward resolving a wide range of biological issues, including a number of occurrences connected to cancer. Deep learning is an adaptable sector of AI that enables the automatic extraction of features. It is increasingly being used in various fields of cancer research, both scientific and clinical. In this study, several current applications of AI in oncology, including the situations in which deep learning has effectively addressed intractable disputes, are discussed. This study also discusses the challenges that need to be surmounted before such an application of AI may be implemented more broadly. Similarly, it brings to light resources and data sets that can assist in maximizing the potential of AI. Essential insights in oncology may be generated based on the development of novel methodologies and uses of AI, making it possible for substantial changes to be made to clinical practice.
The “Africa Rising”: An Empirical Analysis of the Determinants of Per-Capita Growth
Authors: Scalamonti Francesco
Published: July 2023

In developing economies, the race toward inclusive development has prompted researchers to reconsider the drivers of growth in view of achieving the Sustainable Development Goals (SDGs). This study aims to explore the determinants of African growth after analysing reference literature to select the explanatory variables.

The paper identifies the robust drivers of growth of 54 African countries over the period 2010-2019, where the data source is more complete.As a data source, the main international organisations (UN, WB, IMF) have been considered.

We employ a system dynamic panel estimator (GMM-sys) without and with added exogenous regressors for a robustness check. As far as we know, we have not found any studies analysing the determinants of growth in a panel of 54 African countries and/or using GMM estimators with data referring to the last decade. We have used the real per-capita GDP as a dependent variable.

Our findings indicate that, in addition to initial conditions of the per-capita GDP, different macroeconomic factors such as fixed investments, inflation, openness, productivity, unemployment, received remittance, external debt, and terms-of-trade such as imports and exports from or to HDCs, and imports from LMDCs in Southern-Asia are robustly correlated with African growth.We conclude that institutional and business environments are particularly important in explaining African growth.
Simultaneity in Minkowski Spacetime, as Parallax
Authors: Pletcher Arthur
Published: July 2023

Minkowski spacetime parallax uses the shifting plane of simultaneity (POS), of an accelerating inertial reference frame (IRF), while referencing a distant signal (such as a pulsar) with regularly recurring intervals. The distance of the signal's source can be derived from the Lorentz transfer equations and the rate at which the intervals are changing, due to the shifting (POS) during acceleration. The advantage of this method of measuring distance is that: Per the Lorentz transfer equations, time displacement actually increases with distance \(x\), so using time displacement as a parallax to triangulate vast distances (approaching the cosmic microwave background) becomes feasible. The Time-Dependent Hubble Parameter can be approximated, using this method.

Such a method of measurement is well justified, as an alternative to conventional methods of redshift spectroscopy surveys, or CMB temperature fluctuations, with the intent of resolving the lingering "Hubble Tension".
Is creeping abandon of human cancer defences evolutionarily favoured?
Authors: Rahm Alexander D. , Pratley Pierre
Published: July 2023

Among the animal species on which observations are available, humans have a uniquely high lifetime risk to suffer from cancer - over 38%, compared to less than 10% for all observed other species (except species suffering from environmental pollution). Peto's paradox shows that this cannot simply be explained by mathematical models which view cancer genesis as a stochastic process, with resulting risks polynomial in lifespan and body mass - whales have a longer lifespan and about 30 times the human body mass, however their cancer risk remains constant throughout their life rather than increasing sharply after female reproductive age as observed in humans. Rather, it is well documented in the literature that species-specific tumour suppression mechanisms allow for large lifespan and body mass. Chimpanzees, being closely related to humans, have a very low cancer risk, and hence the weakness of human cancer defence is likely to have resulted from the specific development of homo sapiens. As this weakness appears past the reproductive years, a prominent hypothesis blames it to antagonistic pleiotropy. However, homo sapiens having lived in small tribes during most of its development, natural selection is likely to also have acted at the level of tribes, and higher degrees of inbreeding would quite certainly have been detrimental to a tribe. And males of high social status can attract new reproductive partners again and again until an age that has seen several generations grow, which in case of a not-so-large tribe would have considerably narrowed down its genetic pool. Furthermore, lowering tumour suppression activities might save calories and hence benefit tribes with limited food production; and individuals suffering from cancer after female reproductive age could still have made contributions to parental/grandparental care, while no more being attractive as a reproductive partner. So, we arrive at the mentioned hypothesis: Is creeping abandon of human cancer defences evolutionarily favoured?
"Sex" and "gender" as constitutional categories — Critical notes from iusfeminist legal dogmatics
Authors: Torres Díaz María Concepción
Published: July 2023

The article invites reflection on the apparent neutrality of legal discourse and the importance of detecting gender biases and/or stereotypes. Hence, it begins by alluding to the Nobel laureate in Economics, Daniel Kahneman (2011), who in one of his works invites us to visualise two lines of equal size, but which, at first glance, appear to have a different extension. The Nobel laureate in economics states that what is seen and observed is never neutral. Hence the importance of stopping to think about the form of socialisation of the sex-gender system in order to subsequently reflect on the terms in which the legal discourse has outlined the subject of Law (normative model of the human) and has recognised rights, and its effects from the point of view of interpretation and normative application.
