When Everything Gets Mixed up and Tangled: Rouletabille in Russia or the Reporter Facing the Conspiracy
Authors:   CARISM, Panthéon-Assas Université, LEGAVRE Jean-Baptiste
Published: November 2024

In 1913, Gaston Leroux, a former journalist, published Rouletabille chez le tsar as a serial, the third of eight wise books. By highlighting the stereotypes and intersections characterizing the representations of conspiracy that inform it, the novel also invites us to consider two essential aspects for anyone interested in journalism: on the one hand, the intertextuality between Leroux’s work as a reporter and that of the novelist he became, and on the other, a central reflection on the relationship between reason and emotion in journalistic work.
Narratives on Criminal Associations in the “Network Society”: Which Literary Reconfigurations for Which Conspiracies?
Authors: DUCOUX Antoine
Published: November 2024

This article argues that contemporary fictions of organized crime reinscribe, in many ways, the imaginary of conspiracy in narrative structures rooted in immediate history, while aiming to critique new ramified and diffuse systems of power. Which procedures are used to uncover the secrecy surrounding these organizations? How do these works reformulate concerns about the localization of power in today’s “network society” that has emerged with economic globalization? Using examples from contemporary Italian literature, I will examine the ways in which authors write about mafia practices, accompanying the social sciences’ reclassification of organized crime as a phenomenon of power. I will also ponder the effects generated by these narratives, in which the distancing of conspiracy theories does not exclude certain reformulations of them with other terms.

Rail inspection is essential to ensure the safety and performance of the rail system. In rail inspection, object detection is an important task to locate and identify damage or obstructions on the rail. This research discusses the use of Sobel features on three convolutional neural network (CNN) architectures, namely VGG-16, ResNet50, and InceptionV3 for object detection in rail inspection. The purpose of this research is to improve the accuracy of object detection in rail inspection by utilizing the edge information obtained from the Sobel filter. This research involves several stages, namely collecting rail image data, image processing with the Sobel filter, feature extraction using three CNN architectures, namely VGG-16, ResNet50, and InceptionV3, and evaluating object detection performance using accuracy metrics. The results show that the use of Sobel features in the three CNN architectures can improve the accuracy of object detection in rail inspection. The evaluation results show that the ResNet50 model provides the best performance with detection accuracy reaching 96%, followed by the InceptionV3 model with 90% accuracy, and the VGG-16 model with 90% accuracy. Based on the results of this study, it can be concluded that the use of Sobel features in CNN architecture can improve object detection accuracy in rail inspection. In addition, the ResNet50 model has the best performance compared to the VGG-16 and InceptionV3 models in object detection in rail inspection. This can be a reference in the development of future rail inspection object detection systems.

Published: November 2024

While the number of AIDS-related deaths continues to rise, efforts have been made to transform the disease into a manageable chronic condition. HIV protease inhibitors have become central to combination therapy. As a result, these inhibitors have become a major focus of anti-HIV drug development. This research takes a data-driven approach to drug development through the use of quantitative structure-activity relationship (QSAR) analysis. A dataset of 450 anti-HIV drugs was used to construct and validate models. Using extensive validation methods and various machine learning algorithms, the results clearly showed that the "ET" regression outperformed the other models (“XGB”, “LGBM”, “DT”, “RF”, “GB”, “Bag”, and “HGB”) in terms of goodness of fit, predictivity, generalizability, and model robustness. Promising compounds were subjected to molecular docking and molecular dynamics simulation, resulting in drugs with favourable pharmacokinetic and pharmacodynamic properties that consistently interact with the therapeutic target.

Published: November 2024

This work deals with the computer simulation of low- and medium energy (E0=0.5÷10 keV) N+, Ne+, Ar+, Kr+, Be+ и Se+ions sliding collisions on the surface of a Cu(100), Ag(110), Si(001), SiC(001) and GaAs(001) solids, and of the accompanying effects, namely, scattering, sputtering and surface implantation. It has been shown that under these conditions the inelastic energy losses become predominant over the elastic ones. The anomalous energy losses observed experimentally at the grazing ion scattering by the single crystal surface were explained. It has been shown that from the correlation of the experimental and calculated energy distributions of the scattered particles, one may determine a spatial extension of the isolated atomic steps on the single crystal surface damaged by the ion bombardment. Results obtained can be also used to study short-range order in alloys undergoing ordering. Dissociative and non-dissociative desorption of adsorbed molecules were simulated. It was shown that at grazing ion bombardment the intensive nondissociative desorption of adsorbed molecules is possible. A preferential emission of Cu atoms in the case of Cu3Au (001) surface sputtering is observed. It was shown that in the case of grazing ion bombardment the layer-by-layer sputtering is possible and its optimum are observed within the small angle range of the glancing angles near the threshold sputtering angle. The obtained results allow to select the optimum conditions for obtaining implanted depth distributions with demanded shape in narrow near-surface region (5–10 atomic layers) of crystals. The highly sensitive layer-by-layer analysis method was proposed on the basis of layer-by-layer sputtering mechanism.

Published: November 2024

This paper presents a model that allows to describe the absorption of hydrogen isotopes by the investigated sample under the following conditions: a thin sample with known geometric dimensions is saturated from the gas phase with hydrogen isotopes at the given temperature in a chamber of known volume and the initial hydrogen isotope pressure in the chamber. Using the developed model, it was possible to describe perfectly the experimental results on the absorption of a three-component mixture of hydrogen isotopes and to determine the interaction parameters of hydrogen isotopes with vanadium V4Cr4Ti alloy. In particular, the solubility constant and the diffusion coefficient of hydrogen isotopes in the alloy were determined, as well as the parameters of their Arrhenius dependences. In the future, the proposed model can be used to simulate the processes of hydrogen storage in nuclear reactor facilities (NR), thermonuclear reactors (TNR) and petrochemical industries.

Published: November 2024

In this paper, we present the results of studies of the irradiation effect with low-energy He+2 ions with an energy of 30 keV (15 keV per charge) on the structural properties of Cu films. As a result of irradiation of initial samples with He+2 ions with a dose of 1·1016 ion/cm2, a change in the Cu surface morphology of films is observed, and the formation of nanoscale inclusions of hexagonal shape is observed. An increase in the irradiation dose to 1·1017 ion/cm2 and higher leads to the formation of cracks and amorphous oxide inclusions on the sample surface. It is established that an increase in the irradiation dose leads to a decrease in the degree of crystallinity and a change in the basic crystallographic characteristics.

Authors: Kupchyshyn A. I. , Niyazov M. N. , Taipova B. G. , Hodarina N. N.
Published: November 2024

A facility for studying the properties of bottom sediments of water bodies by optical method has been developed. From the obtained curves of dependence of density (I) on time (t) the regularities having the same nature for different radiation sources are revealed. Given the intensity of red and green rays, depending on the time, are almost the same, therefore, the effect of these radiations on the bottom sediments is similar. The curves of intensity (I) versus time (t) are satisfactorily described in the framework of the exponential (cascade-probabilistic) model proposed by the authors. Material irradiated in 2016 is less active than material irradiated in 2018. The reason for this behavior is the partial extinction of microorganisms within two years in containers. The flux of gamma radiation in turn increases the activity of the biomaterial immediately after its irradiation.

Published: November 2024

An important technical problem in the study of high-temperature corrosion of graphite materials and SiC-C structures in water vapor in vacuum is to ensure a stable partial pressure (0.001–1.0 Pa) of water vapor in the sample zone. Since the temperature in the sample zone can reach 1400–1700 K, then it is not possible to locate sensors for measuring the vapor pressure there. The paper proposes a method of using metal surfaces of existing or specially introduced elements of a vacuum system (receivers, tanks, pipelines) as a source of water for their controlled heating. Using the computer model of the gas-vacuum environment of the corrosion plant, the ratio of water pressures at the point of sample location and at the point of sampling of the mass analyzer is calculated. The resulting ratio and the analog signal of the mass analyzer (water peak, 18 amu) are used for PID control of the desorption temperature to achieve the required vapor pressure.
DETERMINING REGIONAL BACKGROUND FREQUENCY OF STABLE TRANSLOCATIONS IN THE POPULATION LIVING IN THE TERRITORY ADJACENT TO THE SEMIPALATINSK TEST SITE

Published: November 2024

The paper presents results of the regional background frequency of stable translocations using in situ fluorescent hybridization in different age groups, which ranges from 1.42±0.3 to 4.9±0.5 per 1000 cells. It found that frequency of stable chromosome aberrations revealed by FISH-technique increases with age. This is due to the fact that with age chromosome stability, DNA reparation and regeneration reduction progressively decelerate. The impact of bad habits such as smoking is the most studied sign affecting the level of translocations; therefore, correlation was made between the level of stable chromosome damage and this bad habit in age groups of interest. Background frequency of stable chromosome damage was calculated by means of equipment of automated cytogenetic platform based on the electronic Carl Zeiss AxioImager Z2 fluorescent microscope, automatic Metafer 4/M Search, ISIS (MetaSystems, Germany) metaphase search and analysis system and using commercial whole chromosome DNA probes for chromosomes 1, 4, 12.

TRLIF AND TRLIC LASER SPECTROSCOPY AND DETECTION OF ACTINIDES/LANTHANIDES IN SOLUTIONS
Authors: Izosimov I. N.
Published: November 2024

At present the most efficient methods of detection of actinides and lanthanides in solutions are methods based on registration of actinides with time resolution, time-resolved laser induced fluorescence (TRLIF) spectroscopy. TRLIF may be applied for biological samples analysis. Pu, Np, and some U compounds do not produce direct luminescence in solutions, but when excited by laser radiation, they can induce chemiluminescence of chemiluminogen (luminol in our experiments). The presence of a time delay between the pulse of laser radiation and the chemiluminescence pulse allows using time resolution (TR) procedure for detection of chemiluminescence (TRLIC). Using chemiluminescence of solutions, we found an approach to registration of plutonium, uranium, and other elements in solutions with a high sensitivity in excitation of plutonium and uranium with a pulse laser with tunable wavelength. A multi-step scheme of chemiluminescence excitation makes this procedure not only highly sensitive but also highly selective method of detection of substances.

Published: November 2024

Complex experimental studies on the effect of electron irradiation on the deposition rate of activated sludge in water systems by optical method were carried out. To determine the parameters of activated sludge (biomaterial), an experimental setup was created. Silt in an amount of 1 g, placed in a flask of water with a volume of 25 ml, was carefully shaken and installed between the laser and the detector. The dependence of light intensity (green and red laser lines) on time was removed. The obtained dependences of the density (r) on time (t) have the same nature for different radiation sources.

The measurements of geometrical and physical parameters of the processed medical products were carried out. The density of samples was measured both in industrial packaging and in individual products. Experimental studies on the passage of electrons with an energy of 2 MeV through medical products: cotton wool, syringes. The absorption coefficients of the electron beam for two materials (cotton wool, syringes) are obtained. It was found that when irradiating products from the sides there is a greater uniformity of dose distribution in samples of cotton wool and syringes. From the results of the experiment it follows that such irradiation leads to the fact that the unevenness of the dose of the impact on the thickness of the sample for cotton wool is about 5 %, and for syringes – 3 %.

3D-scanning at the stage of collecting data on an unknown component is proposed as a method to improve the remote identification efficiency. In contrast to the digital photo image, the 3D-model based on the 3D-scanned image of an unknown component is shown to simplify analyzing the external view of this component (shape, design features), to allow higher-precision determination of its important identification parameters (geometrical dimensions and density), and as a consequence, higher-probability prediction of its origin. The comparative analysis of the scanned component and its anticipated basic preimage through superposition of 3D-models by means of Creo Parametric software package is demonstrated.

Published: November 2024

During 1976–1987 in the former USSR on the territory of Irkutsk and Chita area (the Eastern Siberia) and Sakha Republic (Yakutia) ten peaceful nuclear explosions were conducted in scientific and commercial applications. The peaceful nuclear explosions have yields in the range of 3.2 to 15 kt. The events were registered by regional analog seismic stations network located in the Baikal rift system and surroundings at distances from 173 to 1407 km. The paper shows the first results of the treatment of these seismograms. Using arrival times, regional travel time curves for the both crustal and mantle seismic phases (Pn, Pg, Sn and Sg) were constructed and regional velocities of seismic waves were determined for the whole region and three main tectonic structures – Siberian platform, Baikal-Patom uplift and Transbaikal block. The velocities obtained well correlated with the data known on the velocity structure of the Earth’s crust and upper mantle of the Baikal rift system.

While awaiting entry-into-force, the IMS is operating in test mode yet, even now, monitoring data have potential use among the scientist for the social welfare means. Contribution to the earthquake hazard and related earthquake engineering determinations is a big development and knowledge expansion of the one of the cited technology i.e. seismic. In this direction Indonesian region bounded by 14°S–10°N and 93–141°E, which is one of the most seismically Trans-Asian and Circum-Pacific belts type active plate regions of the world where large to great earthquakes have occurred during the past hundred years have been considered. Nineteen years recent earthquake data from June 13, 1999 to July 10, 2017 have been taken from International Monitoring System (IMS) Network setup by Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO), Vienna Austria. These data analyses shows that earthquake occurrences agrees with the Gumbel’s Type I extreme distribution function and has been applied to analyses those maximum magnitude data with a satisfactory degree of correlation (0.96). The earthquake hazard that existed in Indonesian region been quantified in terms of recurrence periods and probabilities of occurrence of earthquake of any given magnitude. This investigation indicates that the most probable largest annual earthquakes are close to 6.0. Also, most probable earthquake that may occur in an interval of 50 years is estimated as 6.8. Other medium to large size earthquakes which are expected to occur in this region has been predicted that may help in engineering investigations at particular site and decision making problems if planning to develop certain region for infrastructural activities.

A systematic study of changes in the structure and mechanical characteristics (microhardness and wear resistance) of the AMЦ aluminum alloy, depending on the number of passes and the angle between the pressing channels at the ECAP. The work shows that by varying the number of passes, different grain sizes and different values of mechanical characteristics can be obtained. It was found that with a decrease in grain size, the microhardness of the AMЦ alloy increases by 4.5 times compared to the initial state. It is shown that after ECAP-12, the mass loss decreases, which shows an increase in the wear resistance of the AMЦ alloy by 13–14%. It was identified that after the ECAP of the AMЦ, the strength characteristics increase, and the plasticity decreases when the transition to the ultrathingrained state.
