description: The strongest magnetic storm has happened on 22 July 2009 in the deep minimum of the solar cycle activity. This storm was short, only about one day duration. In the storm main phase, the SymHvalue reached almost -100 nT at ~ 06 UT, after that, the direction of the Interplanetary Magnetic Field (IMF) became northward, and the storm recovery phase started. However, at about 07 UT, the IMF turned southward, that caused the beginning of the second step of this magnetic storm. Near the maximum of this stage, the strong irregularity is appeared when the IMF Byand Bzcomponents simultaneously changed from ~+7 nT to ~-14 nT and from ~-15 nT to ~+5 nT correspondingly. In this paper we analyzed the global effects these abrupt IMF changes on the geomagnetic activity at the high-latitudes. The strong dayside magnetic bay occurred at the Scandinavian IMAGE magnetometer chain. As a rule, such dayside magnetic bays are observed under the absent of the night side substorm activity. However, in the considered event, the dayside polar magnetic bay was accompanied by the intense high-latitude disturbances observed not only in the night side, but in the global scale as well. We suppose that this dayside polar magnetic bay was not typical and was not associated with the local polar field aligned currents enhancement. Probably, it was caused by the development of the global complicated system of the ionospheric currents as a response to the abrupt IMF changes.

description: Dynamics of charged particles in the vicinity of a rotating black hole embedded in the external large-scale magnetic field is numerically investigated. In particular, we consider a non-axisymmetric model in which the asymptotically uniform magnetic field is inclined with respect to the axis of rotation. We study the effect of inclination onto the prevailing dynamic regime of particle motion, i.e. we ask whether the inclined field allows regular trajectories or if instead, the deterministic chaos dominates the motion. In this contribution we further discuss the role of initial condition, particularly, the initial azimuthal angle. To characterize the measure of chaoticness we compute maximal Lyapunov exponents and employ the method of Recurrence Quantification Analysis.

description: Lifetimes were measured for transitions in the superdeformed band of Hg192 with the Doppler-shift attenuation method. The results yield an essentially constant quadrupole moment of 202 e b and indicate that the sidefeeding lifetimes are of the same order as the state lifetimes. The data are consistent with calculations using the cranked Woods-Saxon Strutinsky method with pairing.

description: The results of a comprehensive analysis of a moderate polar substorm (the term was proposed by Kleimenova et al.,2012) are presented. Data of multi-instrument observations in auroral zone and polar cap were used. The onset took place near the poleward boundary of the auroral oval that is not typical for traditional substorms. It was preceded by two negative excursions of IMF Bz component with 15-min interval between them, two enhancements of antisunward convection in polar cap with approximately the same repetition period and 15-minute oscillations in geomagnetic H-component in auroral zone. The distribution of pulsation intensity along meridian has two maxima at equatorial and pole boundaries of auroral oval where pulsations occurred in out-of-phase mode resembling the field-line resonance event. The fast poleward shift of auroras (auroral breakup) had a form of poleward progressing auroral torch that also is not typical for ordinary substorms. The set of satellite and ground data fits better in the near-tail current disruption scenario.

description: Double parton distribution functions (dPDF), accessible in high energy proton-proton and proton nucleus collisions, encode information on how partons inside a proton are correlated among each other and could represent a tool to explore the 3D proton structure. In recent papers, double parton correlations have been studied in the valence quark region, by means of constituent quark models. This framework allows to understand clearly the dynamical origin of the correlations and to establish which, among the features of the results, are model independent. Recent relevant results, obtained in a relativistic light-front scheme, able to overcome some drawbacks of previous calculations, such as the poor support, will be presented. Peculiar transverse momentum correlations, generated by the correct treatment of the boosts, are obtained. The role of spin correlations will be also shown. In this covariant approach, the symmetries of the dPDFs are unambiguously reproduced. The study of the QCD evolution of the model results has been performed in the valence sector, showing that, in some cases, the effect of evolution does not cancel that of correlations.

description: In this report we analyzed the occurrence of GPS fluctuations during moderate geomagnetic storm on 4 -5 November and during minor geomagnetic disturbances on 9 November 2018, as well as their impact on the performance of the satellite navigation system. Despite the low intensity of the disturbances these events caused serious disruptions in the operation of global navigation satellite systems (GNSS) at the high latitudes. We analyzed the similarities and differences in the occurrence of the TEC fluctuations and positioning errors for two periods of disturbances. The positioning errors were determined using the GIPSY -OASIS software. We found rather good similarity between the intensity of the TEC fluctuations and positioning errors.

Besides the strong inelastic scattering channel, twelve transfer processes were identified, ranging from 1 n to 2α transfer; typically, cross coincidences between the γ-rays from both products were observed. Potential spectroscopic applications are indicated.

description: Iron emission lines at 6.4-6.97 keV, identified with Kalpha radiative transitions, are among the strongest discrete features in the X-ray band. These are one of the most powerful probes to infer the properties of the plasma in the innermost part of the accretion disk around a compact object. In this paper we present a recent Suzaku observation, 100-ks effective exposure, of the atoll source and X-ray burster 4U 1705-44, where we clearly detect signatures of a reflection component which is distorted by the high-velocity motion in the accretion disk. The reflection component consists of a broad iron line at about 6.4 keV and a Compton bump at high X-ray energies, around 20 keV. All these features are consistently fitted with a reflection model, and we find that in the hard state the smearing parameters are remarkably similar to those found in a previous XMM-Newton observation performed in the soft state. In particular, we find that the inner disk radius is Rin = 17 +/- 5 Rg (where Rg is the Gravitational radius, GM/c^2), the emissivity dependence from the disk radius is -2.5 +/- 0.5, the inclination angle with respect to the line of sight is i = 43 +/- 5 degrees, and the outer radius of the emitting region in the disk is Rout > 200 Rg. We note that the accretion disk does not appear to be truncated at large radii, although the source is in a hard state at about 3 % of the Eddington luminosity for a neutron star. We also find evidence of a broad emission line at low energies, at 3.03 +/- 0.03 keV, compatible with emission from mildly ionized Argon (Ar XVI-XVII). Argon transitions are not included in the self-consistent reflection models that we used and we therefore added an extra component to our model to fit this feature. The low energy line appears compatible with being smeared by the same inner disk parameters found for the reflection component.

description: We consider second order explicit and implicit two-step time-discrete schemes for wave-type equations. We derive optimal order aposteriori estimates controlling the time discretization error. Our analysis, has been motivated by the need to provide aposteriori estimates for the popular leap-frog method (also known as Verlet's method in molecular dynamics literature); it is extended, however, to general cosine-type second order methods. The estimators are based on a novel reconstruction of the time-dependent component of the approximation. Numerical experiments confirm similarity of convergence rates of the proposed estimators and of the theoretical convergence rate of the true error.

description: We present an analysis of approximately 200 hours of observations of the pulsars J1634$-$5107, J1717$-$4054 and J1853$+$0505, taken over the course of 14.7 yr. We show that all of these objects exhibit long term nulls and radio-emitting phases (i.e. minutes to many hours), as well as considerable nulling fractions (NFs) in the range $\sim67\,\% - 90\,\%$. PSR J1717$-$4054 is also found to exhibit short timescale nulls ($1 - 40~P$) and burst phases ($\lesssim 200~P$) during its radio-emitting phases. This behaviour acts to modulate the NF, and therefore the detection rate of the source, over timescales of minutes. Furthermore, PSR J1853$+$0505 is shown to exhibit a weak emission state, in addition to its strong and null states, after sufficient pulse integration. This further indicates that nulls may often only represent transitions to weaker emission states which are below the sensitivity thresholds of particular observing systems. In addition, we detected a peak-to-peak variation of $33\pm1\,\%$ in the spin-down rate of PSR J1717$-$4054, over timescales of hundreds of days. However, no long-term correlation with emission variation was found.

description: The condensation energy and the specific heat jump of a two-dimensional Hubbard model, suitable to discuss high-$T_c$ superconductors, is studied. In this work, the Hubbard model is investigated by the Green's function method within a $n$-pole approximation, which allows to consider superconductivity with $d_{x^2-y^2}$-wave pairing. In the present scenario, the pseudogap regime emerges when the antiferromagnetic (AF) correlations become sufficiently strong to move to lower energies the region around of the nodal point $(π,π)$ on the renormalized bands. It is observed that above a given total occupation $n_T$, the specific heat jump $ΔC$ and also the condensation energy $U(0)$ decrease signaling the presence of the pseudogap.

These nuclei are among the most deformed known at low spin and excitation energy. The level structures in the odd-A nuclei show that the h11/2 intruder orbital plays an important role in stabilizing the deformation in this region.

description: AbstractLeonardo da Vinci (1452–1519) was the main figure of the Renaissance by his works in many fields of arts and sciences. It was in the same time mathematician, painter, architect and engineer. But his remarkable contributions were also in botany, music, philosophy, anatomy and physiology. Leonardo is revered for his technological ingenuity. "All our knowledge has its origins in our perceptions" he noted. Based on the natural ability to observe and understand the details of a phenomenon, he developed his power of attaining the gist in many fields of human knowledge. Briefly, this was a skill named intuition doubled by the gift of quickness and accurate talent to make drawings and sketches. His books of notes and manuscripts are the source of study for scientist, revealing continuously surprises. The paper presents some aspects of the Leonardo's contribution in the domain of "strength of materials" referring to the behavior of elastic bars. From the geometrical constructions he studied the qualitative aspects of beam bending, preparing to try the establishment of stresses causing the arch failure. Through experimental studies, Leonardo observed and annotated the phenomenon of elastic deformation of elastic springs. Assuming that cross-section is rectangular, Leonardo concluded that plane sections remain plane and perpendicular to the midplane after deformation. This is the geometrical hypothesis of the Bernoulli-Euler beam theory, presented by Leonard approximately 250 years earlier.

The artery is modelled as a highly flexible infinite elastic tube with thin, straight, circular and homogeneous walls embedded in the tissue. It is assumed that blood is an incompressible micropolar fluid. The flow rate, micro-gyration and cross-sectional area are calculated as functions of blood pressure pulse. The effects of increasing of the hematocrit on the magnitude of flow velocity and micro-gyration are analyzed. Seven micropolar viscosity coefficients are introduced as function of the initial particle concentration and are reconstructed by a genetic algorithm based on experimental data.

description: Abstract: There are few publications which bring up the subject of the ropeway cable under moving in-service load. Our main goal is to establish the so-called differential equation of a moving load on the ropeway cable of a zip line entertainment facility. The unknown is its movement speed as a function of time, but the direct integration of this equation is not possible. This impediment is bypassed by changing the variable “time”, with the variable “angle” swept by the radius vector.However, the new first order constant coefficient differential nonlinear equation can be easily solved. The solution obtained was applied in a real case study and a comparative study is presented plotting speed variation and acceleration of mobile load.
The discovery of the first superhumps
Creators: name: Vogt, Nikolaus
Publisher: name: Zenodo
Year: 2023

description: The first "superhumps" have been detected by the author as a visiting astronomer at the ESO 1-m-telescope in December 1972, when observing the dwarf nova VW Hydri during one of its superoutbursts.   After a brief description of the photoelectric photometry as the best technology available 50 years ago and resuming what was generally known on cataclysmic variables and particularly on dwarf novae at this epoch, a description of the superhump detection and its consequences is given. In the first publication from 1974 the term "superhump" was not yet present, it was suggested by Brian Warner in 1975. Soon it turned out that superhumps refer to a widespread phenomenon among SU-UMa type dwarf novae and some other classes of cataclysmic variables, not depending on the orbital inclination of the binary. One of the steps towards their understanding could be the detection by the author, published in 1982, that the accretion disc transforms into an eccentric shape during a superoutburst. This deformation is confirmed by Smoothed Particle Hydrodynamics (SPH), however, the physical cause of superhumps is still not totally understood, even now after half a century since their detection.

description: Detailed spectroscopic studies of the discrete γ-rays feeding and deexciting a 41 2-, 4.6 MeV level in 191Hg are reported. The resulting decay scheme indicates single-particle nature for the states above the 41 2- level. At moderate spin, the corresponding particle alignment mode competes favorably with collective oblate rotation. It is suggested that this sequence is associated with a non-collective prolate shape (ε{lunate}=0.1-0.15, γ≅-120°).

description: The observation of a superdeformed band in the nucleus Hg192 is reported. The band has sixteen transitions with an average energy spacing of 36 keV and an average dynamic moment of inertia scrI(2) of 112 Latin small letter h with stroke2 MeV-1. This band persists to rather low rotational frequency (Latin small letter h with stroke0.125 MeV) and is proposed to extend in spin from 10+ to 42+. No transitions linking the superdeformed states and the low deformation yrast levels were found and the decay out of the superdeformed band appears to be statistical. This is the second case of superdeformation in the 190 region.

description: We derive new types of $U(1)^n$ Born-Infeld actions based on N=2 special geometry in four dimensions. As in the single vector multiplet (n=1) case, the non--linear actions originate, in a particular limit, from quadratic expressions in the Maxwell fields. The dynamics is encoded in a set of coefficients $d_{ABC}$ related to the third derivative of the holomorphic prepotential and in an SU(2) triplet of N=2 Fayet-Iliopoulos charges, which must be suitably chosen to preserve a residual N=1 supersymmetry.

description: Negli ultimi decenni, caratterizzati da uno sviluppo senza precedenti della tecnologia, la tutela della privacy online è diventata un diritto fondamentale di ogni cittadino, continuamente messo in pericolo dalle immense quantità di dati che vengono archiviate ed elaborate su ognuno di noi. Nonostante l'impegno delle istituzioni e l'interesse dei singoli individui nell'argomento, ci troviamo però di fronte ad un paradosso: tutti sembrano sensibili al problema, ma in pochi agiscono concretamente per proteggersi nel loro quotidiano utilizzo del web. Dopo aver analizzato quindi le ragioni di questo paradosso la ricerca si è concentrata sull'ideazione di un servizio unitario operante su più fronti con l'obiettivo di aumentare la consapevolezza degli utenti in merito alla propria privacy online, spronandoli tramite l'utilizzo di varie nudge ad adottare comportamenti più coscienti e ad agire più attivamente per tutelare la propria privacy. Nel dettaglio, sono state ideate varie funzioni: per la sintesi e la valutazione delle privacy policy dei servizi, per mostrare quali società sono state impattate in passato da violazioni, per rendere più semplice l'applicazione dei diritti forniti dal GPDR e infine per proteggere l'utente dai tracker presenti nel web e dalle applicazioni troppo invadenti. Nel farlo si è creato un parallelismo tra la prossemica del mondo reale e quella del mondo virtuale, rendendo più semplice visualizzare in maniera efficace ed empatica l'effettiva invadenza dei servizi quotidianamente utilizzati da ogni individuo. Il progetto è stato realizzato sotto forma di web app, applicazione mobile ed estensione per il browser, in modo tale da fornire all’utente ogni strumento necessario alla difesa della propria privacy, contribuendo così ad una società che aspiri ad essere sempre più protetta dal “capitalismo della sorveglianza”.

description: С помощью искусственной нейросети (ИНС) типа слоя Кохонена выполнена классификация образов причинно-следственной связи суббуревой активности с параметрами солнечного ветра и межпланетного магнитного поля отвечающими солнечным потокам типа межпланетное магнитное облако (ММО) в интервалы их воздействия на земную магнитосферу. Исследование выполнено с использованием минутных данных, отвечающих интервалам наблюдений 33 ММО, зарегистрированных в 1998-2012 гг. Для каждого интервала ММО анализировались параметры солнечного ветра, компоненты вектора межпланетного магнитного поля (ММП), а также значения SYM/H и AL индексов магнитной активности. На основе имеющихся данных была создана информационная база, включающая в себя 34 параметра. Анализ классификационных результатов позволяет отождествлять выделенные классы суббурь с конкретной комбинацией возмущений параметров солнечного ветра и ММП в магнитных облаках солнечного ветра.

description: We have examined a solution to the FRW model of the Einstein and de Sitter Universe, often termed the standard model of cosmology, using wide values for the normalized cosmological constant Omega_L and spacetime curvature Omega_k with proposed values of normalized matter density. These solutions were evaluated using a combination of the third type of elliptical equations and were found to display critical points for redshift z, between 1 and 3, when Omega_L is positive. These critical points occur at values for normalized cosmological constant higher than those currently thought important, though we find this solution interesting because the Omega_L term may increase in dominance as the Universe evolves bringing this discontinuity into importance. We also find positive Omega_L tends towards attractive at values of z which are commonly observed for distant galaxies.

description: Данные спутника DMSPF7 за 1986 г. использованы для изучения поведения ионного давления на границах авроральных высыпаний. Рассмотрено более 5000 пролетов в секторе 21:00-24:00 MLT. Величина ионного давления определялась как среднее значение, полученное за 5 секунд наблюдений, что соответствует расстоянию длинной ~40 км на участках траектории спутника, примыкающих к границам высыпаний. Показано, что при всех уровнях магнитной активности давления плазмы на границах авроральных высыпаний почти линейно возрастает с ростом динамического давления солнечного ветра (Psw). Получено широтное положение границ высыпаний и давление плазмы на границах в периоды всех фаз среднестатистической суббури интенсивностью в максимуме AL=-410 нТл. Показано, что с увеличением динамического давления наблюдается не только значительный рост давления плазмы на границах авроральных высыпаний, но и изменение широтного положения самих границ. С ростом Pswширота приполюсной границы овала увеличивается, в то время как широта экваториальной границы уменьшается. Несмотря на значительное расширение области высыпаний, широтный градиент давления между границами овала вспокойные периоды (AL=-18 нТл, ММП Bz=+1.4 нТл) при отсутствии каких-либо возмущений в авроральной зоне увеличивается примерно в два раза от 0.06 нПа/град до 0.12 нПа/град.

description: This article first examines the many factors that the licensor takes into account when deciding how stringent of a licence to issue. It draws attention to the wide range of motives that could influence licence decision-making. The article goes on to say that when works have a strong appeal to the community of open-source contributors. For instance, when contributors stand to significantly benefit from signalling incentives or when the licences are well-trusted, permissive licences will be more common. The restrictive ones will be shared when the demand is more brittle. It should be noted that these licences are intricate legal contracts that haven’t been put to the test in court. There are still many questions concerning how to interpret them. Whether the licence stipulates that the source code must be made publicly available when changed versions of the software are distributed, such a clause is occasionally referred to as a “copyleft” clause. Whether the licence prohibits the infringement of music. In this article, the study highlights the dichotomy of copyright and copywrong with music infringement and copyleft and copyright in the digital system and open and free software.

description: In 2010 France, when Nicolas Sarkozy was the President, began to evacuate “illegal” Roma camps and to repatriate (also “voluntarily”) hundreds of communitarian Roma, especially when they were of Romanian or Bulgarian extraction: EU Institutions reacted severely, accusing French government to infringe EU law in subject of free circulation and non-discrimination. This paper tries to throw light on the real evolution of French policy about Roma (only formal changes seem to have taken place) and the actual role of the EU: the concept of “re-integration” seems to have got the upper hand over “citizenship”, partially narrowing the sphere of protection of Roma as European citizens.

description: The fast spread of the COVID-19 over the world pressured scientists to find its cures. Especially, with the disastrous results, it engendered from human life losses to long-term impacts on infected people’s health and the huge financial losses. In addition to the massive efforts made by researchers and medicals on finding safe, smart, fast, and efficient methods to accurately make an early diagnosis of the COVID-19. Some researchers focused on finding drugs to treat the disease and its symptoms, others worked on creating effective vaccines, while several concentrated on finding inhibitors for the key enzymes of the virus, to reduce its spreading and reproduction inside the human body. These enzymes’ inhibitors are usually found in aliments, plants, fungi, or even in some drugs. Since these inhibitors slow and halt the replication of the virus in the human body, they can help fight it at an early stage saving the patient from death risk. Moreover, if the human body’s immune system gets rid of the virus at the early stage it can be spared from the disastrous sequels it may leave inside the patient’s body. Our research aims to find aliments and plants that are rich in these inhibitors. In this paper, we developed a deep learning application that is trained with various aliments, plants, and drugs to detect if a component contains SARS-CoV-2 key inhibitor(s) intending to help them find more sources containing these inhibitors. The application is trained to identify various sources rich in thirteen coronavirus-2 key inhibitors. The sources are currently just aliments, plants, and seeds and the identification is done by their names.

description: Fully energy-damped yields from the Mg32 reaction have been measured at center-of-mass energies of Ec.m.=51.6 and 60.5 MeV with the use of an experimental arrangement where both of the resulting heavy fragments could be detected in coincidence. Energy, velocity, and angular distributions of the reaction fragments have been determined. The cross sections prior to secondary light-particle emission have been deduced for the breakup of the compound system into different mass channels. These data are discussed in terms of two possible reaction mechanisms: fusion followed by fission and deep-inelastic orbiting.
An Irreducible Massive Superspin One Half Action Built From the Chiral Dotted Spinor Superfield

description: Although the chiral dotted spinor superfield should describe a Massive Superspin One Half multiplet, it has not been obvious how to derive this from an action. In this paper this is done by including a chiral undotted spinor superfield, finding the BRST transformations that govern both of these, and then finding the action as an invariant of the transformations. It turns out that both kinds of spinor superfields are needed. Moreover, the BRST transformations for the two kinds of chiral spinor superfields are generated from each other by a special involution that exchanges Grassmann odd (even) sources with Grassmann even (odd) fields.
