K. pneumoniae, which produces Carbapenemases, is of public health importance because of its resistance to antimicrobials. K. Pneumoniae is identified phenotypically by its large pink mucus appearance on MacConkey agar because of lactose fermentation and by bacteriological, microscopic, and biochemical tests using the VITK 2 device. Antimicrobial susceptibility testing was performed by Kirby-Bauer disc diffusion. Klebsiella pneumoniae represented 5.3% (n = 16). It is highly resistant to antibiotics used to treat wound infections and shows the highest rate of resistance with cefepime 11(68.8%), followed by Ertapenem 9(56.3%), Doripenem and Imipenem 7(43.8%), and Meropenem 6(37.5%). Carbapenemases resistance was identified by phenotype through the Hodge test and also detection of Carbapenemases genes by polymerase chain reaction. The results showed the presence of the bla SHV 16 gene (100%) in K. pneumoniae isolates. The results showed that there were 4 isolates (25%) positive for the bla AMPC gene. The results also showed the presence of the bla KPC gene in two isolates (12.5%). The bla GES gene was not found in K. pneumoniae isolates. In general, the isolates were resistant to carbapenem and cefepime antibiotics. Five random samples were examined by publishing the results of the sequence analysis by BLAST in (NCBI) and the Mega 7 polymorphism detection program: it was found that there was no difference between the sequences, but rather the match was with the bacterium Klebsiella pneumoniae.

INTRODUCTION. Breast Cancer-Related Lymphedema (BCRL) is the most common complication after radical treatment of breast cancer (BC). Currently, there are no molecular therapeutic targets whose pharmacologic action could prevent edema, making it necessary to study the efficacy of non-pharmacologic techniques.
AIM. To study the effectiveness of non-medication technologies in BCRL to develop recommendations for practical application based on the analysis of systematic reviews and meta-analyses of randomized controlled trials (RCTs).
MATERIALS AND METHODS. The search was conducted in the Physiotherapy Evidence-Based Database (PEDro, 2002–2024) using the keywords: “lymphedema”, “upper limbs”, “breast cancer”. A total of 203 sources were selected as of March 2024.
RESULTS AND DISCUSSION. Numerous studies have found that the use of early postoperative physical exercise with a gradual expansion of the load in patients at risk of developing BCRL is a safe and effective method of rehabilitation. The effectiveness of early preventive use of manual lymphatic drainage (MLD) in 4 RCTs was studied in a Cochrane review. However, the clinical effectiveness of early prophylactic use of MLD to prevent BCRL remains insufficiently proven. In contrast, prophylactic use of compression sleeves has been shown to reduce and delay the onset of arm lymphedema in women at high risk of developing BCRL during the first year after breast cancer surgery. Studies have also confirmed the effectiveness of an early Prospective Surveillance Model using bioimpedance spectroscopy for early detection and immediate treatment of BCRL. It has been proven that in order to reduce the volume of a limb with BCRL, it is necessary to prescribe an intensive phase of complex decongestive therapy (CDT) for at least 3 weeks. Studies have also proven the effectiveness of using a standard or improved intermittent pneumatic compression device in the rehabilitation phases, including at home.
CONCLUSION. To reduce the risk of development and progression of BCRL, modern exercise therapy techniques should be used to increase physical activity in order to control body weight, and educational techniques for self-massage and self-application of compression bandages should be actively used. The “golden” standard for conservative treatment of BCRL remains CDT, which is based on MLD. At the same time, the wider use and development of new methods of hardware lymphatic drainage that imitate MLD, which is a highly resourceful and costly method of treatment for BCRL, is justified. To confirm the clinical effectiveness of improved hardware pneumocompression, additional RCTs assessing long-term treatment results are required.

Published: July 2024

INTRODUCTION. Diabetes mellitus (DM) in patients with lower extremity injuries is a global health problem. The combination of these pathologies in one patient requires rehabilitation measures to restore maximum functional activity and maintain the patients’ initial quality of life. Diabetes as an independent pathology has a negative impact on the patient’s health and also aggravates the recovery period after traumatic bone injury, increasing the risk of adverse outcomes in the early and late postoperative periods.
AIM. To analyze the scientific data of the last ten years on the use of medical rehabilitation methods in patients with lower extremity injuries and diabetes mellitus.
MAIN CONTENT. The search was conducted in Web of Science, PubMed, and Scopus according to PRISMA guidelines and initially identified 181 records. Of these, 45 articles were included in the study with publication periods 2013–2023. Key words used: lower limb injuries, diabetes mellitus, rehabilitation, mechanotherapy, physical therapy, physiotherapy. The literature review analyzes publications on the basis of which a description is made that in case of injuries of the lower extremities in patients with diabetes, the participation of specialists from a multidisciplinary team is necessary to draw up an optimal rehabilitation program aimed at preventing the occurrence of complications and their progression, achieving a speedy and complete recovery of lost functions. A personalized approach, individually selected therapy methods and the use of modern technologies will help achieve the best results in the recovery of patients with diabetes and lower extremity injuries.
CONCLUSION. The review formulated a conclusion about the main objectives of rehabilitation: which include: control of glucose levels and metabolic disorders; examination and care of damaged tissues in order to prevent the development of ulcers and infection of injured skin; gradual increase in physical activity; goals should take into account the individual characteristics of the patient; the use of physiotherapy methods to improve microcirculation and activate tissue regeneration (transcutaneous electrical nerve stimulation (TENS), electrophoresis, magnetic fields, ultratonotherapy, cryotherapy, laser therapy, darsonvalization, pulsed electric fields, ultrasound therapy, ozokerite therapy and peloid therapy); the use of mechanotherapy with biofeedback and robotic systems to increase overall endurance, strength, improve balance function and form the correct walking stereotype (rehabilitation track with visual feedback about walking C-Mill).

Authors: Nazarova Kristina M. , Nalobina Anna N.
Published: July 2024

INTRODUCTION. Pisa syndrome is a postural deformity that can lead to impaired posture control and balance in patients with Parkinson’s disease (PD), which increases the risk of injury and reduces the quality of life.
AIM. To study the effect of the Pisa syndrome on postural control, balance and gait of patients with Parkinson’s disease.
HYPOTHESIS. It is assumed that patients with PD with the Pisa syndrome will have specific features of postural control and balance, which must be taken into account when developing rehabilitation technologies for correcting postural disorders.
MATERIALS AND METHODS. As part of the comparative study, 30 people of both sexes were examined, all study participants received levodopa drugs in an individual dosage selected by a neurologist-parkinsonologist. The subjects were divided into 2 groups of 15 people each according to the principle of the presence of the Pisa syndrome and its absence. Criteria for inclusion in the groups: voluntary informed consent of persons with PD for the study; age from 45–80 years, stage 2–4 of Hoehn-Yahr Parkinson’s disease, absence of other diseases and gross cognitive impairment. The diagnosis was carried out using the COBS Physiomed stabilometry system and the EQ-5D-3L questionnaire, a diary of falls and a dynamic gait index (DGI). The reliability of the differences was determined by the Mann-Whitney U-test. Data processing was carried out using the Statistica 10 program.
RESULTS. Significant differences were revealed in the parameter of the coordination index of the Standing Balance test for the right leg and on the EQ-5D-3L scale at a significance level of p 0.05, in the group of people with PD without the Pisa syndrome, the quality of life was significantly higher, the number of falls was significantly higher in the group of people suffering from PD with the Pisa syndrome towers.
DISCUSSION. Walking with a change of direction and multitasking is the most significant problem for people with PD with the Pisa syndrome, the differences between the groups are significant at a significance level of p 0.01.
CONCLUSION. Patients with PD and Pisa syndrome have altered gait associated with body tilt forward, instability and decreased balance control.

Published: July 2024

In the evolving landscape of medical documentation, the necessity for efficient and accurate record-keeping systems is paramount, especially in specialised fields such as neurology where precision in terminology is crucial. This paper introduces a pioneering application of a fine-tuned Whisper model, specifically adapted for brain-related medical terms, integrated with an AI-driven system for automated template filling. The proposed system leverages advanced speech recognition technologies to capture doctors' verbal inputs and accurately transcribe these into designated report templates. The process simplifies the documentation workflow, significantly reducing the cognitive and administrative load on healthcare providers by enabling them to focus more on patient care rather than paperwork. Our research details the development and implementation of this innovative system, including the specific adaptations made to the Whisper model to enhance its accuracy with neurology-specific terminology. We also evaluate the system's performance in real-world medical settings and discuss the practical implications of integrating such AI tools in clinical practice. Furthermore, the system's capacity to generate ready-to- print PDF reports not only streamlines the documentation process but also ensures consistency and reliability in medical records. The overarching aim of this project is to demonstrate how targeted AI solutions can address the unique challenges of medical documentation, offering substantial benefits to healthcare providers and patients alike.

Authors: Nachukwu Idibia Clinton , Chukwuma Ofodu Joseph , Genuine Saturday Ebigenibo
Published: July 2024

This study was carried out to experimentally investigate the effect of impeller size with volute clearance and liquid density on the performance of radial blade centrifugal pumps. Three impeller sizes of 121.54mm, 109.38mm and 97.23mm with respective volute clearance of 6mm, 12mm and 18mm were considered, and five different liquid blend which comprise of water, two liquids that are denser than water and two other liquids that are less-dense than water (with respective liquid densities of: 1197 kg/m3 , 1097 kg/m3 , 1000kg/m3 , 898.2 kg/m3 and 798.4 kg/m3 ). In the experimental set-up, the pump flow capacity were varied from 12m3 /hr to 62m3 /hr at interval of 5m3 /hr and the corresponding pump power consumption, attained pump head were recorded and pump efficiency were determined. Microsoft excel was used to evaluate the trend, performance trend was used to develop the pump performance model showing the relationship between the various parameters. The results from the investigation revealed that with the various impeller sizes of 121.54mm, 109.38mm and 97.23mm of respective volute clearance of 6mm, 12mm and 18mm, the attained optimum efficiency were 74.42%, 54.78 and 33.54% respectively at a correspondence optimum pump head of 23.66m, 20.60m and 18.87m. The results also showed that there is a direct relationship between pump power consumption and process liquid density, while showing an inverse linear relationship between the pump instantaneous start up power and impeller diameter. It was therefore concluded among others that liquid with higher density will usually require higher power to initiate and maintain flow at constant flow rate and impeller size. It is then recommended among others that pump designers, application engineers and users of centrifugal pumps should consider possible increase in pump power consumption when working with a process application that has higher tendency for dynamic increase on the process fluid density.

Authors: Khaemba Protas , Sifuna Maxwell
Published: July 2024

This study examines the adoption of One Acre Fund (OAF) agricultural innovations in Bungoma South Sub-County, Kenya, in response to declining maise production. Despite agricultural development programs aiding Kenya's economic growth, research shows low technological acquisition. Qualitative and quantitative data were collected from 204 out of 9,924 OAF-registered farmers using descriptive research design. Inferential statistics were employed to analyse the different phases of adoption, with quantitative data presented in tables. The qualitative findings were analysed using thematic analysis and incorporated into the results of the inferential analysis as narratives. A situational analysis was performed to assess the status of various types of OAF agricultural innovation among smallholder farmers in the study area. Pairwise ranking was implemented to identify advanced acquisition strategies. The findings revealed that the socio-economic characteristics of farmers, such as age (p = 0.002), marital status (p = 0.000), level of education (p = 0.001), family size (p = 0.047), non-farm work (p = 0.327), and size of land (p = 0.110), significantly influenced the adoption of the OAF agricultural innovations. The study also indicated that the adoption phases were impacted by factors such as group memberships (p = 0.047), farm visits (p = 0.012), and training (p = 0.000). Based on the findings, the study recommends the implementation of awareness programs, crop insurance, the establishment of farm cooperatives, and the strengthening of farmers' knowledge systems to enhance OAF maise output and achieve food security.

Authors: Oyinlola Oluwagbemiga , Sussman Tamara , Iwuagwu Anthony
Published: July 2024

Extant literature has reported the challenges and stressors caregivers of people with dementia face globally. Local realities and contexts often shape these challenges. For example, in regions of Africa where the prevalence of caregiving is increasing, beliefs about dementia and limited infrastructures create unique challenges for caregivers, potentially restricting caregivers’ capacities. Yet directions for policy, practice, and research are often informed by research conducted in regions outside of Africa or fail to account for local contexts. This scoping review seeks to understand the knowledge base on regional differences and similarities in the experiences of caregivers supporting persons with dementia in the region of Africa. The review will be guided by Arksey and O’Malley’s five-stage- framework. Five databases: Ageline, MEDLINE, Social Science Abstract, Psych-Info, and African-wide information will be searched. Citations from these databases will be subjected to two levels of screening The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) will describe and document the inclusion and exclusion process. This scoping review will improve our understanding of unique practices and pressures experienced by caregivers of persons with dementia in different localities in Africa. It will also identify support needs and knowledge gaps in African region. Keywords: Dementia, Caregivers, Older Adults, Support Needs, Experiences
Syntax, Technology and Politics: Analyzing Political Facebook Posts
Authors: Afreh Esther Serwaah , Atta-Asamoah Obed , Asare Ebenezer
Published: July 2024

This study used Halliday’s Systemic Functional Linguistics (SFL) theory to analyze syntactic complexity in digital communication. Thirty Facebook posts made between August and December 2023 by John Dramani Mahama, a Ghanaian former president, were analyzed in this study. A textual analysis was conducted on the data. The findings affirmed that grammatical categories are functional. There was a deliberate linguistic strategy marked by a prevalence of declarative sentences and a notable dominance of complex structures in this genre of digital writing. The strategic use of non-finite clauses contributes to the complexity of the discourse. The genre of writing is also characterized by information ranking and integration. The linguistic choices align with the formal expectations of political and digital communication – precision, depth, and engagement. These observations challenge and enrich existing theories of political discourse and communication strategies in the digital era.

Published: July 2024

News summarization is very important in the news analysis process. However, in the summarization process, there are often obstacles such as the large number of news stories and the need for news classification. This research aims to build a simple web-based system that can be used to summarize and classify news which will be very useful in the news analysis process. The proposed summarization method is Textrank, and the news classification method that will be used is KNN. This system is expected to provide an automatic summarization function to make it easier to analyze news content. The data that will be used as the basis for classification modeling is sports news in 3 months, and the classification that will be used to determine whether the news includes sports news in three branches, namely football, rackets or basketball.  Testing of the summarization model using textrank was carried out by applying ROUGE-1 and ROUGE-2, with results of 0.79 and 0.67. Meanwhile, testing the classification model using KNN with k=3 and k=5 is 0.9866 and 0.9666 so k=3 will be used. This system will be built using the web scrapping library, textrank, stopword from PySastrawi, scikit-learn for the classification module using the KNN algorithm, and ngrok for publishing web-based applications. By using ngrok, we can expose the application through internet with a temporary public url without hosting required

The Distribution of Pc5 Ultralow-frequency Waves at Geostationary Orbit
Authors: Loto’aniu Paul T. M. , Inceoglu F.
Published: July 2024

Using GOES magnetometer data spanning over 30 yr, we study the distribution of Pc5 ultralow-frequency waves at geosynchronous orbit. The CLEAN algorithm was applied to detect narrowband Pc5 waves. This method was first used in astronomical radio interferometry, but has since been applied to many other areas. The algorithm allows for identification of multiple individual peaks within the same power spectral density. We found close to 30,000 events in each magnetic field component in field-aligned coordinates. With some exceptions, results were in agreement with previous studies. Wave occurrence along magnetic local time (MLT) was higher in the 18–23 MLT sector. However, the largest accumulated wave amplitudes were observed on the dayside, peaking close to local noon. As expected, wave amplitudes were larger during more active solar wind conditions. For the radial and parallel components, amplitudes were maximum at the interplanetary magnetic field clock angle of −30° to −45°. The resultant database of Pc5 ultralow-frequency wave events can be used to constrain radiation belt models, while the CLEAN method provides a unique technique to automatically detect narrowband plasma waves in the magnetosphere and beyond.

The Next Generation Deep Extragalactic Exploratory Public (NGDEEP) survey program was designed specifically to include Near Infrared Slitless Spectroscopic observations (NGDEEP-NISS) to detect multiple emission lines in as many galaxies as possible and across a wide redshift range using the Near Infrared Imager and Slitless Spectrograph. We present early results obtained from the first set of observations (Epoch 1, 50% of the allocated orbits) of this program (NGDEEP-NISS1). Using a set of independently developed calibration files designed to deal with a complex combination of overlapping spectra, multiple position angles, and multiple cross filters and grisms, in conjunction with a robust and proven algorithm for quantifying contamination from overlapping dispersed spectra, NGDEEP-NISS1 has achieved a 3σ sensitivity limit of 2 × 10−18 erg s−1 cm−2. We demonstrate the power of deep wide field slitless spectroscopy (WFSS) to characterize the star formation rates, and metallicity ([O iii]/Hβ), and dust content, of galaxies at 1 < z < 3.5. The latter showing intriguing initial results on the applicability and assumptions made regarding the use of Case B recombination. Further, we identify the presence of active galactic nuclei and infer the mass of their supermassive black holes using broadened restframe Mg ii and Hβ emission lines. The spectroscopic results are then compared with the physical properties of galaxies extrapolated from fitting spectral energy distribution models to photometry alone. The results clearly demonstrate the unique power and efficiency of WFSS at near-infrared wavelengths over other methods to determine the properties of galaxies across a broad range of redshifts.

Published: July 2024

Cosmic voids identified in the spatial distribution of galaxies provide complementary information to two-point statistics. In particular, constraints on the neutrino mass sum, ∑m

ν
, promise to benefit from the inclusion of void statistics. We perform inference on the CMASS Northern Galactic Cap sample of the third-generation Sloan Digital Sky Survey/Baryon Oscillation Spectroscopic Survey (BOSS) with the aim of constraining ∑m

ν

To extract constraints from these summary statistics we use a simulation-based approach, specifically implicit likelihood inference. We populate approximate gravity-only, particle-neutrino cosmological simulations with an expressive halo occupation distribution model. With a conservative scale cut of

The Atmosphere of HD 149026b: Low Metal Enrichment and Weak Energy Transport
Authors: Gagnebin Anna , Mukherjee Sagnick , Fortney Jonathan J. , Batalha Natasha E.
Published: July 2024

Recent JWST eclipse spectra of the high-density hot Saturn HD 149026b between 2.35 and 5.08 μm have allowed for in-depth study of its atmosphere. To understand its atmospheric properties, we have created a grid of 1D radiative-convective–thermochemical–equilibrium atmosphere models and spectra with PICASO 3.0. In agreement with previous work, we find that the presence of gaseous TiO creates a thermal inversion, which is inconsistent with the data. The presence of gaseous VO, however, which condenses at temperatures 200 K cooler, does not cause such inversions but alters the temperature–pressure profile of the atmosphere. We estimate an atmospheric metallicity of

solar with VO, a factor of ∼10 times smaller than previous work from Bean et al., who relied on atmosphere retrievals. We attribute this significant difference in metallicity to a larger temperature gradient at low pressures in radiative equilibrium models. Such models with lower metallicities readily fit the strong CO2 feature at 4.3 μm. Our lower estimated metallicity makes HD 149026b more consistent with the mass–metallicity relationship for other giant planets. We find a C/O ratio of

A Temperature or Far-ultraviolet Tracer? The HNC/HCN Ratio in M83 on the Scale of Giant Molecular Clouds
Authors: Harada Nanase , Saito Toshiki , Nishimura Yuri , Watanabe Yoshimasa , Sakamoto Kazushi
Published: July 2024

The HNC/HCN ratio is observationally known as a thermometer in Galactic interstellar molecular clouds. A recent study has alternatively suggested that the HNC/HCN ratio is affected by the ultraviolet (UV) field, not by the temperature. We aim to study this ratio on the scale of giant molecular clouds in the barred spiral galaxy M83 towards the southwestern bar end and the central region from Atacama Large Millimeter/submillimeter Array observations, and if possible, distinguish the above scenarios. We compare the high-resolution (40–50 pc) HNC/HCN ratios with the star formation rate from the 3 mm continuum intensity and the molecular mass inferred from the HCN intensities. Our results show that the HNC/HCN ratios do not vary with the star formation rates, star formation efficiencies, or column densities in the bar-end region. In the central region, the HNC/HCN ratios become higher with higher star formation rates, which tend to cause higher temperatures. This result is not consistent with the previously proposed scenario in which the HNC/HCN ratio decreases with increasing temperature. Spectral shapes suggest that this trend may be due to optically thick HCN and optically thin HNC. In addition, we compare the large-scale (∼200 pc) correlation between the dust temperature from the far-IR ratio and the HNC/HCN ratio for the southwestern bar-end region. The HNC/HCN ratio is lower when the dust temperatures are higher. We suggest from the above results that the HNC/HCN ratio depends on the UV radiation field that affects the interstellar medium on the ∼100 pc scale where the column densities are low.
Class Symbolic Regression: Gotta Fit ’Em All
Authors: Tenachi Wassim , Ibata Rodrigo , François Thibaut L. , Diakogiannis Foivos I.
Published: July 2024

We introduce “Class Symbolic Regression” (Class SR), the first framework for automatically finding a single analytical functional form that accurately fits multiple data sets—each realization being governed by its own (possibly) unique set of fitting parameters. This hierarchical framework leverages the common constraint that all the members of a single class of physical phenomena follow a common governing law. Our approach extends the capabilities of our earlier Physical Symbolic Optimization (Φ-SO) framework for symbolic regression, which integrates dimensional analysis constraints and deep reinforcement learning for unsupervised symbolic analytical function discovery from data. Additionally, we introduce the first Class SR benchmark, comprising a series of synthetic physical challenges specifically designed to evaluate such algorithms. We demonstrate the efficacy of our novel approach by applying it to these benchmark challenges and showcase its practical utility for astrophysics by successfully extracting an analytic galaxy potential from a set of simulated orbits approximating stellar streams.
Spinal aneurysmal bone cysts – case series
Authors: Cekov Asen , Tarev Ivan , Kanev Anastas
Published: July 2024

Aneurysmal bone cysts are benign neoplastic lesions that are extensively vascularized and can occasionally exhibit destructive and expanding activity. They typically affect young people, with a small predilection toward females, and most frequently arise during the second decade of life. Aneurysmal bone cysts account for about 1% of all bone tumors and usually develop in long tubular bones, with the spine being much less commonly affected.

We present here three cases of aneurysmal bone cysts in the spinal cord that were surgically treated at the Department of Neurosurgery between 2009 and 2022. These patients were admitted to the clinic with symptoms of spinal cord or vascular compression. The volume of operative intervention was total or subtotal resection of the formation. No postoperative neurological deficits were observed, and no early complications were recorded after the interventions. All patients were discharged from the department with clinical improvement. One underwent reoperation after 4 years because of a cyst recurrence. The diagnosis of aneurysmal bone cyst was confirmed by histological examination in all cases.
A Mature Cyber Power? Drivers, Strategies and Tools of the EU’s International Cyber Engagements
Authors: Pawlak Patryk
Published: July 2024

Le présent article s’attache à expliquer comment, malgré la complexité des dynamiques et des politiques internes, l’UE parvient à influencer les cyberpolitiques au niveau international. L’article soutient que l’UE réussit à naviguer dans ces régimes de gouvernance évolutifs en raison de sa maturité dans différents secteurs de la cyberpolitique, tels que la résilience, la défense, la lutte contre la criminalité et la diplomatie. Cette maturité politique est évaluée à partir de trois éléments clés : la portée et la profondeur de la politique, le paysage institutionnel et les ressources. Comme le montre cet article, le niveau global de maturité de l’UE dans le domaine cyber a cru au cours de la dernière décennie ; or, plus celle-ci est élevée, plus son impact sur la scène internationale est important. L’analyse présentée dans cet article est fondée sur des sources primaires, des documents officiels et les observations de l’auteur résultant de sa participation active à la cyberpolitique de l’UE entre 2012 et 2023.
Sur les rives du Potomac, le centre du système de renseignement et de cyberdéfense des États-Unis
Authors: Guiffard Jonathan
Published: July 2024

La région de Washington D.C. constitue le cœur d’un vaste système de collecte de renseignement, de surveillance et d’action dans l’espace numérique. Comment ce territoire a-t‑il permis l’émergence du cœur du pouvoir topologique américain dans le cyberespace ? Depuis le milieu du xx e  siècle, il abrite un système complexe de renseignement, mais aussi le développement d’Internet dans sa dimension militaire. La convergence de ces deux phénomènes a permis l’émergence, au début du xxi e  siècle, d’un écosystème de cyberdéfense complexe, concentré géographiquement, et toujours en cours de maturation. Néanmoins, ce processus a favorisé prioritairement le développement de la dimension de sécurité nationale, au détriment de la dimension civile de la cyberdéfense qui peine à se structurer dans cet écosystème fragmenté. L’objet de cet article est de proposer une typologie et une analyse territoriale simplifiée de ce système qui constitue le point de départ d’une position américaine favorable dans l’espace numérique.
Une subversion augmentée ? Concepts et acteurs de l’actuelle stratégie cyber russe
Authors: Nocetti Julien
Published: July 2024

Indissociable des mues de la puissance russe depuis la décennie 2010, le cyber représente pour Moscou un levier tactique et stratégique lui permettant d’opérer dans les interstices de la conflictualité en évitant des franchissements de seuil. La spécificité de l’approche russe réside dans l’articulation d’un héritage soviétique et d’une adaptation des services de renseignement aux potentialités nées de la diffusion globale des moyens numériques. Pour mieux éclairer la période ouverte en février 2022 avec l’invasion russe de l’Ukraine, le présent article revient sur les concepts qui alimentent le schéma mental des responsables civils et militaires russes dans le champ cyber, ainsi que sur les différents acteurs mobilisés par les autorités nationales dans le but de diluer la responsabilité de celles-ci.
