Switching Gear: Law Approximation in Ukraine After the Application for EU Membership

In the wake of a full-scale Russian invasion, Ukraine applied for EU membership on 28 February 2022. In a matter of months, it was formally confirmed by the European Council as a candidate country. This has had a plethora of consequences; one of them is the obligation to approximate its national law with the EU acquis in its entirety. Unless there is a change of paradigm in EU pre-accession policy, transitional arrangements are strictly the exception to the rule, and therefore the law approximation effort has to go way beyond existing commitments under the EU-Ukraine Association Agreement, the Energy Community Treaty, and the Civil Aviation Agreement. Such switching of gear in the law approximation process comes with additional layers of complexity. For instance, compliance with the horizontal provisions of the Treaty on the Functioning of the European Union governing freedoms of the internal market requires comprehensive screening of national law before any legislative changes are made. Furthermore, law approximation with EU legal acts which can only apply when a country becomes a Member State must be carefully planned and timed. The legal system must be ready to accommodate EU law, with all the principles governing enforcement, including the direct application of EU regulations. While this is all doable, it must be handled with care, especially in a country whose economy and society at large have been shattered by war

An \u3cem\u3em\u3c/em\u3e-Carboranedicarboxylic Acid Dianilide

The crystal structure of the \u27non hydrogen-bonded\u27 (according to IR data) polymorph of 1,7-bis(phenylcarbamoyl)-1,7-dicarba-closo-dodecaborane(12), C16-H22B10N2O2, has been determined. The two phenylamide groups have a Z configuration [the torsion angles 0-C-N-C are -2.3 (5) and -3.0 (5)°]. As a result both \u27active\u27 protons of these groups are almost completely shielded by other H atoms of the neighbouring carborane nucleus and phenyl substituents, and, therefore, no hydrogen-bonding contacts are found

Modeling the emergence of universality in color naming patterns

The empirical evidence that human color categorization exhibits some universal patterns beyond superficial discrepancies across different cultures is a major breakthrough in cognitive science. As observed in the World Color Survey (WCS), indeed, any two groups of individuals develop quite different categorization patterns, but some universal properties can be identified by a statistical analysis over a large number of populations. Here, we reproduce the WCS in a numerical model in which different populations develop independently their own categorization systems by playing elementary language games. We find that a simple perceptual constraint shared by all humans, namely the human Just Noticeable Difference (JND), is sufficient to trigger the emergence of universal patterns that unconstrained cultural interaction fails to produce. We test the results of our experiment against real data by performing the same statistical analysis proposed to quantify the universal tendencies shown in the WCS [Kay P and Regier T. (2003) Proc. Natl. Acad. Sci. USA 100: 9085-9089], and obtain an excellent quantitative agreement. This work confirms that synthetic modeling has nowadays reached the maturity to contribute significantly to the ongoing debate in cognitive science.Comment: Supplementery Information available here http://www.pnas.org/content/107/6/2403/suppl/DCSupplementa

Kraichnan model of passive scalar advection

A simple model of a passive scalar quantity advected by a Gaussian non-solenoidal ("compressible") velocity field is considered. Large order asymptotes of quantum-field expansions are investigated by instanton approach. The existence of finite convergence radius of the series is proved, a position and a type of the corresponding singularity of the series in the regularization parameter are determined. Anomalous exponents of the main contributions to the structural functions are resummed using new information about the series convergence and two known orders of the expansion.Comment: 21 page

Тенденції розвитку міжнародного туризму

The sphere of international tourism for the period 2000–2018 has been explored and analyzed in the article. The dynamics of the world tourist flows development and income from international tourism are considered, the determinants of development are derived, the regional structure of the world market of tourist services is given. The development of the tourism industry in the world is analyzed by indicators: the number of tourist arrivals, tourism revenues at current prices, total contribution of tourism to GDP. The main tourist regions are analyzed in the context of the study, they are compared both in terms of the number of tourist visits, and a list of the TOP 10 countries by volume of foreign exchange earnings from tourism in recent years. It is concluded that in recent years, there is a continuing upward trend in demand for emerging markets, with old markets such as the European market, partially losing its popularity. In the process of research, it is determined that in the conditions of development of the world economy, expansion of volumes of international trade, improvement of means of transport, communication, increase of internationalization and globalization of the world economy the demand for tourist services increases. One of the peculiarities of the development of the international tourist services market is the globalization of the market, which has reached all sectors of the tourism industry. It is concluded that nowadays international tourism is an important area of international economic activity, a complex sphere that significantly affects both the structure and the situation in the world economy as well as the economies of most individual countries and regions of the world. Tourism development has a stimulating effect on such sectors of the economy as transport, communications, trade, construction, agriculture, production of consumer goods, and іt is one of the most promising areas of structural restructuring of the economy, confirming the amount of foreign exchange earnings from tourism in the world in general and in individual countries. It is the increasing demand for tourism services and the volume of foreign exchange earnings from tourism in the world makes the topic relevant for further research

Novel steady state of a microtubule assembly in a confined geometry

We study the steady state of an assembly of microtubules in a confined volume, analogous to the situation inside a cell where the cell boundary forms a natural barrier to growth. We show that the dynamical equations for growing and shrinking microtubules predict the existence of two steady states, with either exponentially decaying or exponentially increasing distribution of microtubule lengths. We identify the regimes in parameter space corresponding to these steady states. In the latter case, the apparent catastrophe frequency near the boundary was found to be significantly larger than that in the interior. Both the exponential distribution of lengths and the increase in the catastrophe frequency near the cell margin is in excellent agreement with recent experimental observations.Comment: 8 pages, submitted to Phys.
