This study is a part of the Skoltech University project to deploy a swarm of four identical 3U CubeSats in LEO. The CubeSats are to be equipped with gamma-ray sensors and their collective behavior will be exhibited in detecting gamma-ray bursts and coordinated attitude control. We consider a fully magnetic attitude control system, comprising a magnetometer as a part of attitude determination routine and three orthogonal magnetorquers as actuators. Having implemented and tested the conventional three-axis magnetic attitude determination and control algorithms, we proceed to study how the performance of such ADCS may be enhanced by using measurements and state vectors exchange. We interpolate the exchanged data, using the Kriging algorithm in conjunction with Extended Kalman filter and Lyapunov-based controller, since it provides the auto correlation and variance information about the environment of the magnetic field, which is of utmost importance for heterogeneous and noisy fields. In our simulations we compare the performance of the controller for a single satellite to that of the satellite in the swarm of CubeSats, which maintains the form of a regular tetrahedron and carries out distributed measurements with interpolation. Improved attitude stabilization for the latter scenario is demonstrated by mean squared errors. [less ▲]

As a result of digitization, transmedia music projects are becoming the standard format of New Music. These ubiquitous transgressions have led composers such as Johannes Kreidler and Hannes Seidel to the assumption that the notion of music is thus also becoming delimited and beginning to dissolve. In the following, I present a theoretical model that confirms and criticizes this prognosis. The countless border crossings do not lead to a dissolved but to a reflexive notion of music. [less ▲]

This research project focuses on the impacts exerted by the tech schemes behind virtual currencies on the EU framework to prevent the misuse of the financial system and it aims to explore legal challenges posed in the IoM landscape by the double-edged nature of DLTs as both transparency and privacy-oriented. On the one hand, it plans to identify effective legislative and regulatory measures to ensure crypto accountability from an AML/CFT standpoint, as well as to assess the relevant role of pseudonymity. On the other hand, it pursues to discover innovative legal approaches to secure AML/CFT active cooperation in the crypto ecosystem(s), to the end of mitigating anonymity and traceability concerns while respecting both the value of publicity and transparency in the law and the conceptual origin of the crypto economy.

La lutte contre l’épidémie de Covid-19 a conduit l’Union, les Etats membres et les citoyens européen à adopter des mesures radicales. Dans nombre de domaines, ces mesures furent inédites – restrictions des libertés de circulation des personnes dans et hors de l’espace Schengen, activation des dispositifs de chômage partielle au bénéfice de l’ensemble des entreprises impactées par la crise, activation de la clause dérogatoire générale en matière de discipline budgétaire, etc. Le domaine monétaire n’a pas été épargné par la crise sanitaire et les répercussions économiques prises pour contenir la propagation de l’épidémie. Cependant, après dix années passées de crises économiques, bancaires et budgétaires, l’état de crise compose une nouvelle normalité de l’UEM – dans laquelle la présente crise vient s’inscrire. De ce fait, les mesures prises en réaction à la crise de la Covid-19 par la BCE, pour être économiquement significatives, ne présentent pas un caractère inédit juridiquement. Elles n’ont pas la radicalité qu’ont pu avoir en leur temps la mise en œuvre des mesures non-conventionnelles. Il faut penser, comme nous y invite une déclaration de la BCE du 18 mars 2020, que l’institution monétaire s’est réservée une marge de manœuvre pour l’avenir, si la situation économique devait encore se dégrader. Après avoir présenté les mesures sanitaires, prudentielles et monétaires prises par l’Eurosystème et la BCE en réaction à la crise jusqu’à ce jour, les problématiques juridiques seront discutées.

Interactome maps are valuable resources to elucidate protein function and disease mechanisms. Here, we report on an interactome map that focuses on neurodegenerative disease (ND), connects ∼5,000 human proteins via ∼30,000 candidate interactions and is generated by systematic yeast two-hybrid interaction screening of ∼500 ND-related proteins and integration of literature interactions. This network reveals interconnectivity across diseases and links many known ND-causing proteins, such as α-synuclein, TDP-43, and ATXN1, to a host of proteins previously unrelated to NDs. It facilitates the identification of interacting proteins that significantly influence mutant TDP-43 and HTT toxicity in transgenic flies, as well as of ARF-GEP(100) that controls misfolding and aggregation of multiple ND-causing proteins in experimental model systems. Furthermore, it enables the prediction of ND-specific subnetworks and the identification of proteins, such as ATXN1 and MKL1, that are abnormally aggregated in postmortem brains of Alzheimer's disease patients, suggesting widespread protein aggregation in NDs.

In this provocative intellectual biography, architectural historian Mark Wigley makes the surprising claim that the thinking behind modernist architect Konrad Wachsmann’s legendary projects was dominated by the idea of television. While architecture is typically embarrassed by television, preferring to act as if it never happened, Wachsmann fully embraced it. Investigating the archives of one of the most influential designers of the twentieth century, Wigley scrutinizes Wachsmann’s design, research, and teaching, closely reading a succession of unseen drawings, models, photographs, correspondence, publications, syllabi, reports, and manuscripts to argue that Wachsmann is an anti-architect—a student of some of the most influential designers of the 1920s that dedicated thirty-five post–Second World War years to the disappearance of architecture. Wachsmann turned architecture against itself. His hypnotic projects for a new kind of space were organized around the thought that television liberates a different way of living together. Wachsmann dissolved buildings into pulsating mirages that were a huge influence on the experimental avant-gardes of the 1960s and 1970s. But Konrad Wachsmann’s Television: Post-architectural Transmissions demonstrates that this work was even more extreme than the experiments it inspired. The book offers a forensic analysis of a career to show that Wachsmann developed one of the most compelling manifestos of what architecture would need to become in the age of ubiquitous electronics.

The article is devoted tore search the main trends in the tobacco market in the EU and Ukraine, the dynamics of excise tax revenues. Research methods are as follows: scientific abstraction: generalizations and scientific abstraction; historical and logical; extrapolation; spatial; statistical; graphical and tabular methods of visualization. The purpose and objectives of the study are to assess the effects of increasing the tax burden on excise tax and its impact on the tobacco market in Ukraine, calculate the loss of tax revenue due to excise measures of taxpayers and formulate proposals to combat this phenomenon. The xperience of European countries in the field of anti-forestalling regulation is analyzed. It was found that anti-forestalling measures are divided into four types, such as: cap on tax stamps, cap on release for consumption, sell-by date, paying the tax difference. It has been found that in some countries of the EU optimal anti forestalling regulation has been achieved over a period of time, in several stages and through the introduction of several measures at the same time. Determined that the rapid increase of excise tax rates on tobacco products in Ukraine also caused the problem of forestalling. Estimated that due to this the loss of tax revenues in 2015-2019 to reached 7% of excise tax revenues on tobacco products. It has been proved that current anti-forestalling regulation was not sufficiently effective for counteracting the accumulation of tobacco product stocks. The main results of the study are proposes a new anti-forestalling regulation in Ukraine, by improving the existing measure and introducing an additional term for the circulation of tobacco products in wholesale and retail trade with tax stamps purchased in the previous year to three months [less ▲]

Heparansulfate (HS) modifications are master regulators of the cross-talk between cell and matrix and modulate the biological activity of an array of HS binding proteins, including growth factors and chemokines, morphogens and immunity cell receptors. This review will highlight the importance of HS maturation mediated by N-deactetylase/sulfotransferases, 2O- and 6O-sulfotransferases in cancer biology, and will focus on the 3O-sulfotransferases and on the terminal, rare 3O-sulfation, and their important but still enigmatic impact in cancer progression. The review will also discuss the molecular mechanisms of action of these HS modifications with regards to ligand interactions and signaling in the cancer process and their clinical significance.

Le Mégacode civil Dalloz offre aux utilisateurs du Code civil un supplément de substance juridique exclusif : dans une zone d’annotations de jurisprudence spécifique, après la jurisprudence du « petit » Code civil, le Mégacode civil explore la jurisprudence largement méconnue résultant des arrêts non publiés de la Cour de cassation et des décisions inédites des juridictions du fond, révélée par l’interrogation systématique des bases de données juridiques. Le Mégacode civil a fait peau neuve. Sur la forme d’abord, il est désormais divisé en 2 parties : la première, comprend les articles 1er à 1099-1 du code civil, c’est-à-dire les généralités sur la loi, les personnes, les biens, et le droit des successions et des libéralités. La 2e partie, de l’article 1100 à la fin du code civil comprend le droit des contrats et des obligations, la preuve, les contrats spéciaux, les régimes matrimoniaux, les sûretés… Sur le fond ensuite, cette édition voit la création d’une nouvelle zone FOCUS, à la suite des annotations spécifiques du mégacode, afin d’explorer de façon très fine certaines points de jurisprudence. Cette édition comprend plusieurs dizaines de milliers de décisions référencées, donnant une vision plus précise et plus pratique de la jurisprudence, mêlant illustrations, chiffrages et descriptions de tendance permettant d’en comprendre l’évolution et d’en faire bon usage.
