Математическая экономика в эпоху социализма и переход к рынку (часть II)
Authors: Полтерович В.М.
Published: December 2024

Статья посвящена исследованию истории развития экономической мысли в России и ее борьбе с официальной идеологией и попыткам влияния на выбор стратегий социально-экономического развития. Во второй части работы показано, что в этой борьбе проявилось несовершенство мировой экономико-математической теории конца XX в., ориентированной на изучение рыночной конкуренции и не рассматривавшей характерные для плановой экономики механизмы рационирования, очередей и черного рынка. Интенсивные усилия, предпринятые российскими экономистами в этом направлении, запоздали. В развернувшейся в конце 1980-х годов «войне программ» по переходу к рынку победила концепция шоковой терапии. Этому способствовали давление международных организаций, не заботившихся о благосостоянии населения СССР, и отсутствие единства среди российских экономистов. Они объединились друг с другом и с ведущими западными экономистами с запозданием, так что выдвинутая ими программа преобразований уже не могла повлиять на результаты реформ. Тем не менее, усилия экономистов-математиков способствовали формированию в России современного экономического образования и постепенному становлению независимой экономической науки.

Acute aortic dissection on ascending aortic aneurysm in a patient with Marfan disease: about a case
Authors: LAKEHAL Rédha
Published: December 2024

Marfan syndrome is a rare genetic disease. It is characterized by the involvement of
one or more organs and can cause skeletal disorders (tall stature, scoliosis),
ophthalmological disorders (ectopia of the lens), and cardiac disorders (aortic dilation).
The prevalence of Marfan syndrome is estimated at one person in 5000. We report the
case of a young woman with a family history of Marfan syndrome (mother with minor
form and two brothers with major forms) who presented to the emergency department
with chest pain evolving for one week with echocardiography showing aortic dissection
with grade II aortic insufficiency and correct left ventricle function. Angio-scan showed
type A aortic dissection on aneurysmal dilatation of the sinus at 69/67 mm chest X-ray:
showed significant scoliosis. Clinically, there was Marfanoid aspect with
kyphoscoliosis, arachnodactyly, adolichesteomely, positive thumb and wrist sign,
myopia and bilateral lens dislocation. Lab studies were normal. The decision of the
medical-surgical staff was to refuse this patient given the importance of thoracic
malformations and the alteration of her general condition. The announcement of the
diagnosis is an integral part of the overall management process. Management is
multidisciplinary and continuous. Key elements for screening are the aortic root and
mitral valve, eye, and musculoskeletal complications.

Authors: HADJAISSA Hamid
Published: December 2024

Introduction. Chronic hepatitis C virus (HCV) infection is a major public health
problem. Hepatocellular carcinoma HCC is a primary liver cancer; it represents the 5th
cause of cancer in the world and the 3rd cause of cancer mortality. The treatment of
chronic viral hepatitis is undergoing a real revolution. The main objective of this study
is to assess the risk of development of HCC after treatment with direct-acting antivirals.
Patients and methods. This is a descriptive prospective study that seeks to assess
the risk of developing HCC after eradication of hepatitis C virus in patients with chronic
HCV at the cirrhosis stage were collected and treated at the infectiology department
of EPH Batna hospital and at internal medicine department in Barika (Algeria),
between 01/12/2016 and 30/07/2018. Results. A total of 113 chronic carriers of HCV
at cirrhosis stage C (74 women and 39 men) were collected. Eight cases of
hepatocellular carcinoma on cirrhosis were noted in our patients, i.e. 7.07% (8/113).
In 100% of cases, HCC occurred after the end of treatment with antivirals in responding
patients. The mean age of these patients was 62.75 ± 3.14 years, with a sex ratio of
0.33. Risk factors found in this group are distributed as follows: AFP (>12, N): 8
patients (100%), Diabetes: 4 patients (50%), hepatalgia: 4 patients (50%),
dyslipidemia: 3 patients (37.5%), cytolysis: 4 patients (50%), hyper gamma GT: 4
patients (50%), high alkaline phosphatase: 7 patients (87.5%), hypoalbuminemia: 5
patients (62.5%), thrombocytopenia: 6 patients (75%). The average body mass index
is 26.52 ± 1.33. Conclusion. Remnant hepatocellular carcinoma is a serious
complication in cirrhotic patients, all eight cases were diagnosed in our study through
strict screening. Our study showed that HCC can develop even after viral eradication.
Oral health related quality of life. Literature review
Authors: SALAH DERRADJI Neila
Published: December 2024

Oral Health-related quality of life (OHRQoL) is a multidimensional concept. It is defined
as an individual's assessment of how functional, psychological, social factors, pain, or
discomfort affect their well-being in the context of oral health. It is recognized that
when oral health is compromised, overall health and quality of life may be diminished.
Several authors have explored the evolution of OHRQoL and documented the
circumstances that led to its importance. The objective of our study was to provide an
overview through a literature review concerning the development and influencing
factors of the OHRQoL concept, the different measures of oral quality of life, and its
significance in clinical practice. We worked on the Medline database using
the PubMed search engine; the search formula "oral health-related quality of life" was
used for this research, and several filters were applied to retain only 46 articles. The
medical community has recognized the increasing importance of evaluating patientreported outcomes in clinical practice, and research on dental health services will
focus on self-reported quality of life as a secondary or even primary outcome measure
in the evaluation of interventions or community health programs.

July 2018 because of human carcinogenic impurity, denominate Nnitrosodimethylamine (NDMA) which was found in the chemical synthesis process of
Valsartan-PRM. Three critical classes of impurities which organic related-impurities,
elemental-impurities, residual solvents-impurities and particularly the genotoxic must
be controlled in PRM before being put into manufacturing process in order to prevent
potentially serious health problems that are difficult to control.
Management of spontaneous and catamenial pneumothorax
Authors: MORSLI Radia
Published: December 2024

Primary (idiopathic) spontaneous pneumothorax frequently occurs in tall healthy
young men between 15 and 30 years of age. Conservative treatment by thoracic
drainage is proposed for the first episode. In case of recurrence, thoracoscopy with
wedge resection of the apex of the upper lobe and pleurodesis is proposed with a
recurrence rate between 4 and 6%. Catamenial pneumothorax, which occurs within
48 to 72 hours of the menstrual cycle, is probably often mistaken for primary
pneumothorax due to the difficulty in proving thoracic endometriosis. Thoracoscopy
is proposed from the outset to search for foci of endometriosis or diaphragmatic
fenestrations. In case of recurrence, thoracotomy with pleurectomy and hormonal
treatment may be proposed, but with a risk of definitive sterility.

Authors: Hernández-Marañón Edgar J. , Andrade-Torres Antonio , Chen Jie , Pérez-Moreno Jesús , Núñez-Pastrana Rosalía , Llarena-Hernández Régulo C.
Published: December 2024

Introducción. Durante recorridos en bosques  de  pino  del  Parque  Nacional  Pico  de  Orizaba  se  encontraron dos nuevos registros de especies de Cantharellus. Estos hongos silvestres poseen valor de consumo, económico y sociocultural en la Región de las Montañas, Veracruz, México.
Objetivo.  Identificar   y   caracterizar   morfológicamente   las   especies   del   género   ectomicorrícico   Cantharellus
recolectadas en el Parque Nacional Pico de Orizaba.
Materiales y métodos. La recolecta de hongos se hizo entre los meses de junio a noviembre mediante un muestreo sistemático durante cuatro años (2019-2022) en bosques de Pinus hartwegii, P. montezumae y P. pseudostrobus del municipio de Calcahualco, Veracruz. Los ejemplares se caracterizaron morfológicamente y se identificaron molecularmente mediante secuencias concatenadas del factor de elongación de transcripción 1-alpha (tef1-α), así como la región interna de transcripción (ITS3C y ITS4).
Resultados y discusión. Los análisis filogenéticos basados en datos moleculares de los principales clados de Cantharellus (125 secuencias) confirmaron los nuevos registros de las especies Cantharellus roseocanus (acceso GenBank: OQ875962 [ITS2] y OQ876856 [tef1]) y Cantharellus flavus (acceso GenBank: OQ875963 [ITS2] y OQ876857 [tef1]). Las diferencias morfológicas entre C. roseocanus y C. flavus son notables: C. roseocanus se caracteriza por su sombrero convexo y láminas delgadas, mientras que C. flavus presenta un sombrero más plano y robusto; además, las diferencias en aroma y sabor también son relevantes en su uso culinario.
Conclusiones. Los nuevos registros de C. flavus y C. roseocanus en los bosques templados del Parque Nacional Pico de Orizaba contribuyen al conocimiento taxonómico del género Cantharellus, que aún carece de la dilucidación completa.

Authors: Rana Qamar Hayat  , Fida Hussain  , Umer Masood
Published: December 2024

Abstract: In this paper, we propose a voice controlled line following robot with the ability to trace the set path and avoid hurdles while moving autonomously. Line-following robots have been around for decades, but this setup uses AI algorithms and fresnel lenses to improve accuracy More Traditional line-following robots often face drawbacks in dealing with intricate environments, but those are addressed here via user control over voice recognition, as-well-as obstacle detection through ultrasonic sensors. The robot is controlled over an Arduino UNO microcontroller and the (advance) features that it offers allows the robot to operate independently with lesser human interactions, the applications of such a robot will span across Transportation & logistics, Industrial Automation and Personal Assistance. This study reveals the potential of this robot to improve precision and flexibility in a realistic usage condition, thereby providing an important tool for automation with safety and productivity.
Developing a framework for business analysts to bridge stakeholder and technical team gaps: Enhancing collaboration and project success
Authors: May Equitozia Eyeregba  , Chukwunweike Mokogwu  , Somto Emmanuel Ewim  , Titilayo Deborah Olorunyomi
Published: December 2024

In today’s dynamic business environment, projects often fail due to misalignment between stakeholders’ needs and technical implementation. Business Analysts (BAs) play a crucial role in bridging the gap between business stakeholders, who focus on strategic objectives, and technical teams, who emphasize implementation details. However, without a structured approach, BAs may struggle to facilitate effective communication and collaboration. Developing a robust framework for BAs can significantly enhance project outcomes by ensuring clear alignment between stakeholder expectations and technical deliverables. A critical component of this framework involves stakeholder identification and analysis. BAs need to clearly understand the interests, expectations, and influence levels of different stakeholders to prioritize requirements effectively. By utilizing tools such as stakeholder matrices and engagement plans, BAs can foster trust and manage expectations, ensuring that business objectives are translated into actionable technical specifications. Effective requirements gathering and documentation is another key element. Techniques such as workshops, interviews, and process mapping can be leveraged to capture detailed business needs. Translating these into clear, structured documentation such as user stories and process flow diagrams ensures technical teams have a precise understanding of project goals, reducing the likelihood of misinterpretation. The use of collaborative tools is essential for enhancing communication between stakeholders and technical teams. Platforms like JIRA and Confluence, along with Agile methodologies, promote iterative feedback loops, ensuring that both parties remain aligned throughout the project lifecycle. Regular check-ins and sprint reviews enable stakeholders to provide real-time feedback, allowing technical teams to adjust solutions to evolving business needs promptly. Additionally, continuous training and upskilling of BAs is vital for the framework’s success. As projects become more complex, BAs must be proficient not only in communication and documentation but also in leveraging data analytics and emerging technologies to drive insights. By developing a comprehensive framework that encompasses stakeholder engagement, clear documentation, and collaborative practices, organizations can optimize project success rates, streamline workflows, and foster a culture of continuous improvement.  Ultimately, the role of BAs is becoming increasingly strategic as organizations strive to remain agile and responsive in a fast-evolving market landscape.

O objetivo deste estudo é identificar, analisar e demonstrar de forma fundamentada e relevante, obedecendo as legislações correntes e vigentes, se há possíveis vantagens em um planejamento tributário bem fundamentado referente as operações de arrendamento mercantil na modalidade operacional para o arrendatário no Brasil. As empresas poderão utilizar vários meios e instrumentos que após serem interpretados e avaliados podem chegar a reduções nos custos e, posteriormente alcançar de forma licita e maximizada os melhores resultados econômicos e financeiros para o empresário. Desta forma, qualquer vantagem referente ao processo de redução dos custos e das despesas será uma diferença significativa que os gestores das empresas poderão alcançar e acrescentar nas operações da empresa, que sempre buscam oportunidades presentes e significativas em suas operações. De acordo, com os diversos assuntos polêmicos que estão presentes na teoria da contabilidade e na legislação tributária, será discorrido sobre o arrendamento mercantil na modalidade operacional. A metodologia utilizada na elaboração é descritiva e bibliográfica. Conforme levantamento feito em livros, legislação, sites e técnica de análise documental indireta. Os benefícios fiscais e os aspectos contábeis serão abordados e demonstrados de forma comparativa na operação de arrendamento mercantil operacional, em duas operações de uma empresa, sendo que uma é operação de arrendamento e outra de venda. Os objetivos foram alcançados com a identificação significante que os tributos fiscais na operação de arrendamento mercantil operacional são apresentados pela a não incidência do ICMS nas operações de remessa para arrendamento.

O tromboembolismo aórtico em felinos trata-se de uma síndrome clínica ocasionada por um trombo que se desprende, migrando geralmente até a trifurcação aórtica, onde obstrui a circulação sanguínea, causando isquemia dos membros. A trombectomia, alternativa de tratamento a ser realizada para esta enfermidade, consiste em um procedimento cirúrgico que visa a retirada do trombo para o retorno da circulação. Este trabalho tem como objetivo relatar o procedimento cirúrgico de trombectomia em um felino que apresentou paralisia dos membros pélvicos repentinamente. O paciente foi diagnosticado e submetido a cirurgia que devolveu-lhe o pulso femoral e, posteriormente, o movimento dos membros. Embora pouco relatada e realizada na medicina veterinária, a trombectomia pode ser um tratamento de sucesso, desde que realizada por um cirurgião experiente, especializado e, principalmente, com o conhecimento necessário do caso, considerando também a estabilidade clínica do paciente.

Un certain nombre de problèmes métrologiques urgents nécessitent l’introduction de technologies de réseau. En métrologie, résoudre le problème de l'intégration des étalons, des instruments de mesure individuels, des capteurs et des réseaux de capteurs dans un réseau mondial est une tâche extrêmement importante. La fiabilité de l'interaction avec les instruments distants, ainsi que la sécurité et la confidentialité des échanges de données sont l'un des problèmes affirmés de l'infrastructure numérique métrologique. La création du composant Grid IE fait de ce système un environnement optimal pour surveiller, gérer et maintenir efficacement les ressources de comptage. Un tel système offre le plus haut niveau de sécurité dans la transmission, le stockage et le traitement des données de mesure, ainsi qu'un haut niveau de fiabilité des résultats de mesure. Cela ouvre également de nouvelles possibilités en termes de traçabilité métrologique. De plus, l'intégration de l'infrastructure numérique NMI et Metrology Cloud avec EGI et EOSC peut être une bonne solution pour la transformation numérique de la métrologie. Cependant, dans ce cas, il est nécessaire d'éliminer la contradiction entre « transparence » et « confidentialité » des données de mesure.
L’évolution différentielle pour la meilleure approximation uniforme des splines

Published: December 2024

L’évolution différentielle est une technique de recherche stochastique basée sur la population. Elle a donné des résultats remarquables sur de nombreux problèmes d’optimisation en raison de sa simplicité et de sa puissance de recherche. Des opérateurs de mutation, de croisement et de sélection sont utilisés à chaque génération pour faire évoluer la population vers l’optimum global. Nous proposons l’algorithme d’évolution différentielle pour traiter le problème de la meilleure approximation spline uniforme dans le cas des nœuds fixes. Les performances de l’algorithme d’évolution différentielle dépendent essentiellement du choix d’une stratégie de génération de vecteurs d’essai (c’est-à-dire des opérateurs de mutation et de croisement) et des paramètres de contrôle qui leur sont associés. C’est pourquoi différentes stratégies et combinaisons de valeurs de paramètres de contrôle sont comparées. Les résultats de la comparaison sont donnés. Pour le problème considéré, les meilleures stratégies de génération de vecteurs d’essai sont déterminées. L’efficacité de l’algorithme proposé est démontrée sur des exemples numériques qui impliquent l’approximation de fonctions par des splines de différents degrés et défauts.
Models of buoyancy-driven dykes using continuum plasticity and fracture mechanics: a comparison

Abstract. Magmatic dykes are thought to play an important role in the thermomechanics of tectonic rifting of the lithosphere. Our understanding of this role is limited by the lack of models that consistently capture the interaction between magmatism, including dyking, and tectonic deformation. While linear elastic fracture mechanics (LEFM) has provided a basis for understanding the mechanics of dykes, it is difficult to consistently incorporate LEFM into geodynamic models. Here we further develop a continuum theory that represents dykes as plastic tensile failure in a two-phase, Stokes–Darcy model with a poro- viscoelastic–viscoplastic (poro-VEVP) rheological law (Li et al., 2023). We validate this approach by making quantitative comparison with LEFM, enabled by a novel poro-LEFM formulation. The comparison shows that dykes in our continuum theory propagate slowly—a consequence of Darcian drag on the magma. Moreover, dissipation of mechanical energy in the poro-VEVP model implies a high critical stress intensity in LEFM. We improve the poro-VEVP model by reformulating the compaction stress and incorporating anisotropic permeability in regions of plastic failure.

Abstract. Unmanned aircraft systems (UAS) are gradually being established in environmental research to study boundary layer conditions and phenomena in situ; however, due to payload limitations, UAS can typically measure only a limited number of atmospheric variables simultaneously. Here we present the Flying Laboratory (FLab), a hexacopter equipped with six instruments to measure aerosol particles (particle number concentration and size distribution; PM1/2.5 and black carbon mass concentration), trace gases (CO2, O3), and meteorological variables (temperature, relative humidity, pressure, wind) in the lower troposphere in real time and with high temporal resolution. The instrumentation has been selected to provide an overview of relevant variables in urban and semi-urban environments and especially in the vicinity of aerosol sources. This paper describes the development of the technical setup of the Flying Laboratory, the characterization of the measurements with respect to horizontal and vertical motion of the UAS, and the optimization of measurement flight patterns. During two field experiments, FLab was applied to bridge the gap between ground-based and aircraft-based profiling measurements and to perform hourly vertical profiling flights up to 300 m above a ground-based reference station for eight hours. These applications demonstrate the capability of FLab to capture the evolution of the lower convective boundary layer during the day and the vertical particle transport in the afternoon up to 200 m above ground.
