OF CREATING REMOTELY CONTROLLED COMBAT MODULES FOR LIGHT ARMORED VEHICLES
Authors: Butenko O. , Tsuria E. , Gordeev S. 
Published: March 2021

The article substantiates the need to create a remotely controlled combat module to equip light armored vehicles (LAV) manufactured at domestic enterprises of the defense complex. The main purpose of LAV is to perform some of the tasks of combined-arms battle and its support, namely: the transportation of personnel, the elimination of enemy’s manpower out of the battle formation, patrolling on the second and third lines of defense of the Joint Forces Operation.
NATO nations procure the following remotely controlled combat modules: United States - M151 Protector RWS and PROTECTOR CROWS II (manufactured by Kongsberg, Norway); United Kingdom - Enforcer (Selex Galilleo, UK) and Protector (Kongsberg, Norway); Germany - light and heavy modules FLW 100 and FLW 200 (manufactured by Krauss-Maffei, Germany).
Remote controlled combat modules occupy a significant niche in the arsenal of modern ground forces. At present, the Armed Forces of Ukraine do not have remotely controlled combat modules that can be used on light armored vehicles. When developing requirements for the remotely controlled combat module, it is advisable to consider the ability to perform basic combat missions by the light armored vehicles and the characteristics of the weapons that will be integrated into the remotely controlled combat module. Weapons that a light armored vehicle is equipped with are used in close combat to solve a large number of different fire missions. The remotely controlled combat module mounted on light armored vehicles is generally used to defeat the line-of-sight targets.
The characteristics of weapons that may be integrated into the remotely controlled combat module and the proposed ammunition load are considered.
In order to simplify design decisions when installing the remotely controlled combat modules on light armored vehicles and for the purpose of performing the task effectively, it is necessary to solve the problem of creating remotely controlled combat modules with a much smaller weight than existing models.
Integration of the aforementioned remotely controlled combat modules into light armored vehicles will allow carrying out tasks on reinforcement of checkpoints, force protection of troops, сonvoy and patrol, destruction of fortified enemy objects, reconnaissance, as well as interception and destruction of manpower and armored vehicles, outside of the battle formations. The bulk delivery of light armored vehicles to the troops will further enhance the mobility of the warfare. Light armored vehicles can be used extensively by air assault troops, mountain assault and motorized infantry formations, territorial defense units.
TEETH AND GEAR WHEELS DESIGN DEVELOPMENT FOR AIRCRAFT REDUCTION TRAINS
Authors: Pilipenko O. , Kolesnik D. , Berezniak A. 
Published: March 2021

The development of designs of teeth, gear wheels and gears, which have found application in gearboxes of aircraft and helicopters, is presented. Parameters of different types of initial generating circuits, their modifications and examples of application corresponding gear wheels in gearboxes of airplanes and helicopters are considered.
The main attention is paid to GOST 13755-2015, developed by CIAMD (Central Institute of Aviation Motor Development) and having a number of advantages over the old GOST 13755-81. The main advantage is achieved by replacing the standard tooth head height with a standard tooth tip thickness. When the teeth work along the entire active part of the gearing line with a profile angle of 250, high contact and bending strength is provided, as well as resistance against galling of the surfaces of the teeth of highly stressed gears.
A further increase in contact strength and resource is ensured by using the initial generating circuit with a profile angle of 280. Gear trains with a guaranteed overlap ratio of 2.0 have a vibration level five times lower and, in general, their bearing capacity is approximately 1.5 times higher than that of highly stressed reduction trains with an overlap ratio less than 2.0. The asymmetrical teeth parameters were chosen to increase the density of the transmitted power, as well as to reduce the dynamic loads and vibration of the gear wheels.
The strength of gear trains according to GOST 13755-2015 significantly exceeds the strength of gear trains according to GOST 13755-81, but the most significant advantage (more than twice) is obtained in terms of noise level. The highest strength of gears with a main circuit angle of 330 occurs at a guide circuit angle of 20 °.
The highest stiffness of arched teeth of all designs provides arched gear trains with high durability and load capacity, which makes it possible to design reduction trains with smaller weight and size specifications.
Are there one or two stocks of Scoranza bleak - Alburnus scoranza Bonaparte, 1845 in Lake Skadar (Montenegro)
Authors: Marić Drago , Burzanović Katarina 
Published: March 2021

This paper provides the first comprehensive information on the Length-Weight Relationship (LWR) of Scoranza bleak (Alburnus scoranza) from the Lake Skadar. The results of the study showed that LWR was different in young and older individual fish. We concluded that no single regression would adequately describe the length-weight relationship for Scoranza bleak in the winter period. Small fish, up to one year old, have positive allometric growth whereas older and larger, negative. The results of this study show that the animals grow equally in the same pattern in both localities (Raduš and Karuč) which shows that there are no two stocks as it was assumed in the past. The condition factor in young Scoranza bleaks was lower than in the elderly. Condition factor decreased significantly during the winter period in older specimens. Based on this, we conclude that Scoranza bleak during the winter is poorly fed/starved, which causes a decrease in the condition factor.Analysis of the total sample, of any species, cannot show by what rule the population grows, if infrapopulation variability is present, because the studied value will depend on the number of individual subgroups. If no infra-population variability is found, the required parameter for the entire population can be calculated. In order to determine population variability, multiple groups must be singled out. Preferably, the number of stratified samples should be at least 6 so that correlation-regression analysis can be performed. In stratified samples, the number of individuals should be between 30-40, for any parameter, in order to compare their mean values. The results of the study show that 50 individuals are sufficient for accurate determination of LWR (or α and b, α is a constant coefficient and b is the slope of the curve.), when it is determined that there is no intrapopulation variability.

Published: March 2021

Abstract
We present a detailed single-pulse analysis for PSR B1929+10 based on observations with the Five-hundred-meter Aperture Spherical radio Telescope (FAST). The main pulse (MP) and interpulse (IP) are found to be modulated with a periodicity of ∼12 times the pulsar’s rotational period (P). The ∼12P modulation is confirmed as a periodic amplitude modulation instead of systematic drifting. The periodic amplitude modulation in the IP is found to be anti-correlated with that in the weak preceding component of the MP (MP_i), but correlated with that in the first two components of the MP (MP_ii), which implies that the modulation patterns in the IP and the MP are phase-locked. What is more interesting is that the modulation in MP_ii is delayed from that in the IP by about 1P. Furthermore, high-sensitivity observations by FAST reveal that weak emission exists between the MP and the IP. In addition, we confirm that the separation between the IP and the MP is independent of radio frequency. The above results are a conundrum for pulsar theories and cannot be satisfactorily explained by the current pulsar models. Therefore, our results observed with FAST provide an opportunity to probe the structure of pulsar emission and the neutron star’s magnetosphere.
Supervirial Temperature or Neon Overabundance? Suzaku Observations of the Milky Way Circumgalactic Medium

Published: March 2021

Abstract
We analyzed Suzaku and Chandra observations of the soft diffuse X-ray background toward four sight lines with the goal of characterizing the X-ray emission from the Milky Way circumgalactic medium (CGM). We identified two thermal components of the CGM, one at a uniform temperature of kT = 0.176 ± 0.008 keV and the other at temperatures in the range kT = 0.65–0.90 keV. The uniform lower-temperature component is consistent with the Galaxy’s virial temperature (∼106 K). The temperatures of the hotter components are similar to that recently discovered (∼107 K) in the sight line to blazar 1ES 1553+113, passing close to the Fermi bubble. Alternatively, the spectra can be described by just one lower-temperature component with supersolar neon abundance, once again similar to that found in the 1ES 1553+113 sight line. The additional hot component or the overabundance of Ne is required at a significance of >4σ, but we cannot distinguish between the two possibilities. These results show that the supervirial temperature gas or an enhanced Ne abundance in the warm-hot gas in the CGM is widespread, and these are not necessarily related to the Fermi bubble.
The X-Ray Pulsar XTE J1858+034 Observed with NuSTAR and Fermi/GBM: Spectral and Timing Characterization plus a Cyclotron Line

Abstract
Accreting X-ray pulsars (XRPs) undergo luminous X-ray outbursts during which the spectral and timing behavior of the neutron star can be studied in detail. We analyze a NuSTAR observation of the XRP XTE J1858+034 during its outburst in 2019. The spectrum is fit with a phenomenological, a semiempirical, and a physical spectral model. A candidate cyclotron line is found at 48 keV, implying a magnetic field of 5.4 × 1012 G at the site of emission. This is also supported by the physical best-fit model. We propose an orbital period of about 81 days based on the visual inspection of the X-ray outburst recurrence time. Based on Fermi/GBM data, the standard disk accretion-torque theory allowed us to infer a distance of 10.9 ± 1.0 kpc. Pulse profiles are single-peaked and show a pulsed fraction that is strongly energy-dependent at least up to 40 keV.

Abstract
Computing and using opacities is a key part of modeling and interpreting data of exoplanetary atmospheres. Since the underlying spectroscopic line lists are constantly expanding and currently include up to ∼1010–1011 transition lines, the opacity calculator codes need to become more powerful. Here we present major upgrades to the HELIOS-K GPU-accelerated opacity calculator and describe the necessary steps to process large line lists within a reasonable amount of time. Besides performance improvements, we include more capabilities and present a toolbox for handling different atomic and molecular data sets, from downloading and preprocessing the data to performing the opacity calculations in a user-friendly way. HELIOS-K supports line lists from ExoMol, HITRAN, HITEMP, NIST, Kurucz, and VALD3. By matching the resolution of 0.1 cm−1 and cutting length of 25 cm−1 used by the ExoCross code for timing performance (251 s excluding data read-in time), HELIOS-K can process the ExoMol BT2 water line list in 12.5 s. Using a resolution of 0.01 cm−1, it takes 45 s, equivalent to about 107 lines s−1. As a wavenumber resolution of 0.01 cm−1 suffices for most exoplanetary atmosphere spectroscopic calculations, we adopt this resolution in calculating opacity functions for several hundred atomic and molecular species and make them freely available on the open-access DACE database. For the opacity calculations of the database, we use a cutting length of 100 cm−1 for molecules and no cutting length for atoms. Our opacities are available for downloading from https://dace.unige.ch/opacityDatabase and may be visualized using https://dace.unige.ch/opacity.

Meaningful Change Thresholds for Patient-Reported Outcomes Measurement Information System (PROMIS) Fatigue and Pain Interference Scores in Patients With Rheumatoid Arthritis
Authors: Beaumont Jennifer L. , Davis Elizabeth S. , Curtis Jeffrey R. , Cella David , Yun Huifeng 
Published: March 2021

ObjectiveWe estimated meaningful change thresholds (MCTs) for Patient-Reported Outcomes Measurement Information System (PROMIS) Fatigue and Pain Interference in rheumatoid arthritis (RA).MethodsThe responsiveness of several patient-reported outcomes (PROs) was assessed among 521 patients with RA in the Arthritis, Rheumatism, and Aging Medical Information Systems (ARAMIS) cohort. PROMIS Fatigue (7-item) and Pain Interference (6-item) short form instruments were administered at baseline, 6 months, and 12 months. Self-reported retrospective changes over the previous 6 months (a lot better/worse, a little better/worse, stayed the same) were obtained at 6 and 12 months’ follow-up. We estimated MCTs using the mean change in PROMIS scores for patients who rated their change “a little better” or “a little worse.”ResultsBaseline fatigue and pain interference scores were near normal (median 54 and 56, respectively). At 6 months, 7.9% of patients reported their fatigue was a little better compared to baseline (mean change [SD]: –2.6 [4.8]) and 22.8% a little worse (1.7 [5.6]). Pain was a little better for 11.5% of patients (–1.9 [6.1]) and a little worse for 24.2% of patients (0.6 [5.7]). At 12 months, results were similar. Thus, the MCT range was 1–2 points for both fatigue and pain interference. Correlations between change scores and retrospective ratings were low (0.13–0.29), indicating possible underestimation of MCT.ConclusionThe group-level MCT for PROMIS Fatigue and Pain Interference is roughly 2–3 points and corresponds to a small effect size, which is consistent with earlier work demonstrating an MCT of 2 points for PROMIS Physical Functioning.

Une liberté dangereuse
Authors: Chabert Catherine 
Published: March 2021

Parmi les représentations d’attente qui président à l’engagement de l’analyse, accéder à « un peu plus de liberté » condense l’essentiel de ses visées : être libéré de ses symptômes et de ses entraves, désirer, aimer et travailler, mais aussi pouvoir se séparer, vivre dans l’indépendance même relative de ses pensées et de ses actes. Ainsi se dessine un idéal qui accorderait au moi et au fonctionnement psychique un statut de sujet à part entière, si on entend par là la capacité à devenir auteur de sa vie. Et pourtant, face à ces espérances conscientes, se dressent les forces antagonistes de la compulsion de répétition, du masochisme et de l’autodestruction, c’est-à-dire le refus de guérir : refus scandaleux qui vient dire que le déplaisir, la souffrance et la douleur s’emparent du transfert et colonisent les résistances pour lutter contre les dangers de la liberté.
La métapsychologie de la trace : du déterminisme à la liberté
Authors: Tran The Jessica 
Published: March 2021

La règle de l’association libre, au principe même de la technique psychanalytique, implique d’emblée un certain paradoxe, puisqu’elle ne s’avère heuristique que dans la mesure où la succession des représentations verbalisées par l’analysant n’est en aucun cas libre ou arbitraire, mais au contraire très précisément déterminée par la vérité de l’inconscient. Si Freud concevait en effet l’existence d’un déterminisme psychique strict, cette conception rend-elle néanmoins caduque toute référence à la liberté du sujet au sein de l’approche psychanalytique ? En revenant à la métapsychologie de la trace, nous pourrons observer que, bien que l’inscription des expériences perceptives sous forme de traces mnésiques soit la condition du déterminisme psychique, cette inscription implique d’emblée une discontinuité entre l’expérience et son inscription, et ouvre la voie à l’expression d’une certaine liberté du sujet, réintroduisant la dimension de l’imprévu au cœur de la psychanalyse.
Devenir plus libre : conquête ou accueil ?
Authors: Bourdin Dominique 
Published: March 2021

Cet article évoque l’itinéraire d’un jeune homme en difficulté pour se séparer de ses parents, soumis à l’emprise d’une tante, hospitalisé en psychiatrie et tenté par un engagement religieux radical : quelles voies pour lui vers la liberté de penser et d’agir ? L’interrogation sur les obstacles à la liberté psychique constitue le cœur de la réflexion. Il s’ensuit un examen du rapport paradoxal entre psychanalyse et liberté, loin de l’illusion de liberté absolue du libre arbitre dans la conception philosophique classique du sujet. Les conceptions psychanalytiques de la remémoration, les élaborations lacaniennes et la réflexion sur la subjectivation sont évoquées avant des propos plus cliniques qui soulignent l’importance de l’agressivité et de la créativité dans le « devenir soi-même ». S’esquisse ainsi une cartographie de voies par lesquelles l’expérience psychanalytique manifeste ses potentialités libératrices.
Le symptôme de la liberté
Authors: Joubert Martin 
Published: March 2021

Quelle opposition plus radicale à l’idée de liberté que l’absolu de la contrainte obsessionnelle ? Pourtant les circuits d’annulation de F., comme ceux de l’homme aux rats, montrent une autre finalité, celle de constituer un obstacle infranchissable, l’assurance d’un espace de liberté, préservé autant d’une intrusion paternelle que de la curiosité de l’analyste. Freud, au bout du compte, voyait dans l’intensité de l’ambivalence obsessionnelle la résultante d’une agressivité infantile « constitutionnellement » excessive. Elle paraît pourtant avoir pu constituer pour l’enfant une solution aux difficultés de la séparation-individuation, et aux enjeux narcissiques des premières confrontations aux pairs, à l’entrée à l’école. Tous deux sont contemporains des conflits de l’analité. Les dés-emboîtements psychiques entre parents et enfants, le réinvestissement de la transitionnalité sont au cœur du traitement de ces pathologies difficiles.
Neurosciences cognitives et idéaux d’autonomie
Authors: Ehrenberg Alain 
Published: March 2021

Les neurosciences cognitives ont acquis une forte légitimité bien au-delà de la neurologie et de la psychiatrie. Leur expertise est demandée dans les domaines les plus divers. Cet article explore l’hypothèse que ce succès social et politique tient à l’acquisition d’une autorité morale. Celle-ci repose sur la transfiguration, dans des langages scientifiques, d’idéaux traditionnels de régularité du comportement. Nés au xviii e siècle et se poursuivant du behaviorisme vers 1900 jusqu’aux neurosciences cognitives de la fin du xx e siècle, ils sont infléchis par des idéaux de changement personnel et d’autonomie individuelle qui se sont diffusés à partir du dernier tiers du xx e siècle. Les neurosciences cognitives apportent à ces idéaux les promesses d’un développement illimité des capacités humaines. Tel est l’horizon d’attente qu’elles suscitent et d’où elles tirent une bonne part de leur autorité.
Malaise dans la sexualité : les nouveaux esclaves de la liberté
Authors: Duparc François 
Published: March 2021

Les psychanalystes sont de plus en plus souvent confrontés à des pathologies individuelles qui relèvent d’un malaise collectif concernant les excès de la libération sexuelle, une idéologie de notre époque. L’incapacité à construire des relations de couple et des modes de vie durables peut aboutir, dans les états-limites, à une sorte d’addiction aux voyages, aux aventures sexuelles, ou à une hyperactivité professionnelle. Le cadre analytique en souffre aussi, mais l’expérience clinique (avec deux cas donnés en exemple) montre que ces sujets peuvent parvenir à intégrer, au-delà d’une séduction pathologique, les autres fantasmes originaires de l’Œdipe qui font ici défaut : une scène primitive plus féconde, une enveloppe maternelle protectrice, et une castration symbolique obéissant à un modèle paternel incorporé sans trop d’excès autoritaires.
