description: Η ιδιωτικοποίηση της δράσης του κράτους εναπόκειται καταρχήν σε απόφαση του νομοθέτη, η οποία ωστόσο υπόκειται σε περιορισμούς που απορρεόυν από το Σύνταγμα. Οι περιορισμοί αυτοί διαφέρουν ανάλογα με το είδος της κρατικής δράσης, αν δηλαδή πρόκειται για άσκηση δημόσιας εξουσίας ή για ανάπτυξη επιχειρηματικής δράσης. Το κράτος δεν εμποδίζεται καταρχήν να ιδιωτικοποιήσει επιχειρηματική δρατηριότητα του. Η απόφαση του αυτή υπόκειται πάντως σε κάποιες συνταγματικές δεσμεύσεις, οι οποίες είναι λιγότερες όταν ο σκοπός της επιχειρηματικής δράσης είναι καθαρά παραγωγικός-κερδοσκοπικός και ισχυρότερες όταν ο επιδιωκόμενος σκοπός είναι ένας άμεσος δημόσιος σκοπός(π.χ. κοινής ωφέλειας). Από την άλλη, το κράτος δεν επιτρέπεται να ιδιωτικοποιήσει την άσκηση δημόσιας εξουσίας, όταν αυτή είναι αναγκαία για την εκπλήρωση των σκοπών του και συνιστά έκφραση κυριαρχίας. Σημαντικό πεδίο κυριαρχικής δράσης του κράτους αποτελεί η παροχή κοινωνικών υπηρεσιών(εκπαίδευσης, υγείας, κοινωνικής ασφάλισης)
description: The legislature may in principle decide to privatise a state activity, his decision however is constrained by the Constitution. These constitutional constraints differ according to the nature of the state activity, i.e. whether there is exersice of public authority or of enterprenial activity. The state is in principle free to decide the privatisation of public enterpriser. His decision is only lesser in the case of pure market activity and more intense when a public purpose is aimed(e.g. utilities) On the other hand, the state may not proivatise the exercise of public authority, which is needed for the implementation of its tasks and is an expression of its sovereignty. An important field of such activity forms the provision of social services(education, heath, social security)
The Supernova Gamma-Ray Burst Connection

Subjects: subject: Astrophysics (astro-ph)

description: The chief distinction between ordinary supernovae and long-soft gamma-ray bursts (GRBs) is the degree of differential rotation in the inner several solar masses when a massive star dies, and GRBs are rare mainly because of the difficulty achieving the necessary high rotation rate. Models that do provide the necessary angular momentum are discussed, with emphasis on a new single star model whose rapid rotation leads to complete mixing on the main sequence and avoids red giant formation. This channel of progenitor evolution also gives a broader range of masses than previous models, and allows the copious production of bursts outside of binaries and at high redshifts. However, even the production of a bare helium core rotating nearly at break up is not, by itself, a sufficient condition to make a gamma-ray burst. Wolf-Rayet mass loss must be low, and will be low in regions of low metallicity. This suggests that bursts at high redshift (low metallicity) will, on the average, be more energetic, have more time structure, and last longer than bursts nearby. Every burst consists of three components: a polar jet (~0.1 radian), high energy, subrelativistic mass ejection (~1 radian), and low velocity equatorial mass that can fall back after the initial explosion. The relative proportions of these three components can give a diverse assortment of supernovae and high energy transients whose properties may vary with redshift.

description: Competitive board games have provided a rich and diverse testbed for artificial intelligence. This paper contends that collaborative board games pose a different challenge to artificial intelligence as it must balance short-term risk mitigation with long-term winning strategies. Collaborative board games task all players to coordinate their different powers or pool their resources to overcome an escalating challenge posed by the board and a stochastic ruleset. This paper focuses on the exemplary collaborative board game Pandemic and presents a rolling horizon evolutionary algorithm designed specifically for this game. The complex way in which the Pandemic game state changes in a stochastic but predictable way required a number of specially designed forward models, macro-action representations for decision-making, and repair functions for the genetic operations of the evolutionary algorithm. Variants of the algorithm which explore optimistic versus pessimistic game state evaluations, different mutation rates and event horizons are compared against a baseline hierarchical policy agent. Results show that an evolutionary approach via short-horizon rollouts can better account for the future dangers that the board may introduce, and guard against them. Results highlight the types of challenges that collaborative board games pose to artificial intelligence, especially for handling multi-player collaboration interactions.

Electronic transmission in a model quantum wire with side coupled quasiperiodic chains: Fano resonance and related issues

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We present exact results for the transmission coefficient of a linear lattice at one or more sites of which we attach a Fibonacci quasiperiodic chain. Two cases have been discussed, viz, when a single quasiperiodic chain is coupled to a site of the host lattice and, when more than one dangling chains are grafted periodically along the backbone. Our interest is to observe the effect of increasing the size of the attached quasiperiodic chain on the transmission profile of the model wire. We find clear signature that, with a side coupled semi-infinite Fibonacci chain, the Cantor set structure of its energy spectrum should generate interesting multifractal character in the transmission spectrum of the host lattice. This gives us an opportunity to control the conductance of such systems and to devise novel switching mechanism that can act over arbitrarily small scales of energy. The Fano profiles in resonance are observed at various intervals of energy as well. Moreover, an increase in the number of such dangling chains may lead to the design of a kind of spin filters. This aspect is discussed.

ABCNet: Attentive Bilateral Contextual Network for Efficient Semantic Segmentation of Fine-Resolution Remote Sensing Images

description: Semantic segmentation of remotely sensed images plays a crucial role in precision agriculture, environmental protection, and economic assessment. In recent years, substantial fine-resolution remote sensing images are available for semantic segmentation. However, due to the complicated information caused by the increased spatial resolution, state-of-the-art deep learning algorithms normally utilize complex network architectures for segmentation, which usually incurs high computational complexity. Specifically, the high-caliber performance of the convolutional neural network (CNN) heavily relies on fine-grained spatial details (fine resolution) and sufficient contextual information (large receptive fields), both of which trigger high computational costs. This crucially impedes their practicability and availability in real-world scenarios that require real-time processing. In this paper, we propose an Attentive Bilateral Contextual Network (ABCNet), a convolutional neural network (CNN) with double branches, with prominently lower computational consumptions compared to the cutting-edge algorithms, while maintaining a competitive accuracy. Code is available at https://github.com/lironui/ABCNet.

description: Ultra-wideband (UWB) technology is a mature technology that contested other wireless technologies in the advent of the IoT but did not achieve the same levels of widespread adoption. In recent years, however, with its potential as a wireless ranging and localization solution, it has regained momentum. Within the robotics field, UWB positioning systems are being increasingly adopted for localizing autonomous ground or aerial robots. In the Industrial IoT (IIoT) domain, its potential for ad-hoc networking and simultaneous positioning is also being explored. This survey overviews the state-of-the-art in UWB networking and localization for robotic and autonomous systems. We also cover novel techniques focusing on more scalable systems, collaborative approaches to localization, ad-hoc networking, and solutions involving machine learning to improve accuracy. This is, to the best of our knowledge, the first survey to put together the robotics and IIoT perspectives and to emphasize novel ranging and positioning modalities. We complete the survey with a discussion on current trends and open research problems.

description: We prepare a quantum state where each site of an optical lattice is occupied by exactly one molecule. This is the same quantum state as in a Mott insulator of molecules in the limit of negligible tunneling. Unlike previous Mott insulators, our system consists of molecules which can collide inelastically. In the absence of the optical lattice these collisions would lead to fast loss of the molecules from the sample. To prepare the state, we start from a Mott insulator of atomic 87Rb with a central region, where each lattice site is occupied by exactly two atoms. We then associate molecules using a Feshbach resonance. Remaining atoms can be removed using blast light. Our method does not rely on the molecule-molecule interaction properties and is therefore applicable to many systems.

description: The article reveals the problem of the poetic of behavior of the naïve writer. The travel-blog of Alexander Lapshin (nick – Puerrtto) is the object of this research. The ‘game’ of the blogger, which lasted for decades, results in the arrest in Belarus in December 2016, followed by extradition to Azerbaijan. A. Lapshin builds a circular biographical narrative with a clearly defined line of ascent from an imaginary spy to a free wanderer and, through the repetition of a prison sentence, to a high human rights mission. The anecdotal nature of the ‘borderline’ performances is emphasized by stripping, mimicking, meaningless remarks, substitutions and confusion with passports. This may be related to the opinion about the implausibility of his stories, which has repeatedly expressed by readers and bloggers.

description: We measured the vibration of a prototype superconducting magnetic bearing (SMB) operating at liquid nitrogen temperature. This prototype system was designed as a breadboard model for LiteBIRD low-frequency telescope (LFT) polarization modulator unit. We set an upper limit of the vibration amplitude at $36~\mathrm{μm}$ at the rotational synchronous frequency. During the rotation, the amplitude of the magnetic field produced varies. From this setup, we compute the static and AC amplitude of the magnetic fields produced by the SMB magnet at the location of the LFT focal plane as $0.24~\mathrm{G}$ and $3\times10^{-5}$$~\mathrm{G}$, respectively. From the AC amplitude, we compute TES critical temperature variation of $7\times10^{-8}$$~\mathrm{K}$ and fractional change of the SQUID flux is $δΦ/Φ_0|_{ac}=3.1\times10^{-5}$. The mechanical vibration can be also estimated to be $3.6\times 10^{-2}$$~\mathrm{N}$ at the rotation mechanism location.

description: FERM3D is a three-dimensional finite element program, for the elastic scattering of a low energy electron from a general polyatomic molecule, which is converted to a potential scattering problem. The code is based on tricubic polynomials in spherical coordinates. The electron-molecule interaction is treated as a sum of three terms: electrostatic, exchange. and polarisation. The electrostatic term can be extracted directly from ab initio codes ({\sc{GAUSSIAN 98}} in the work described here), while the exchange term is approximated using a local density functional. A local polarisation potential based on density functional theory [C. Lee, W. Yang and R. G. Parr, {Phys. Rev. B} {37}, (1988) 785] describes the long range attraction to the molecular target induced by the scattering electron. Photoionisation calculations are also possible and illustrated in the present work. The generality and simplicity of the approach is important in extending electron-scattering calculations to more complex targets than it is possible with other methods.

description: In the framework of photonics with all-dielectric nanoantennas, sub-micro-metric spheres can be exploited for a plethora of applications including vanishing back-scattering, enhanced directivity of a light emitter, beam steering, and large Purcell factors. Here, the potential of a high-throughput fabrication method based on aerosol-spray is shown to form quasi-perfect sub-micrometric spheres of polycrystalline TiO 2 . Spectroscopic investigation of light scattering from individual particles reveals sharp resonances in agreement with Mie theory, neat structural colors, and a high directivity. Owing to the high permittivity and lossless material in use, this method opens the way toward the implementation of isotropic meta-materials and forward-directional sources with magnetic responses at visible and near-UV frequencies, not accessible with conventional Si- and Ge-based Mie resonators.

description: An important goal of medical research is to develop methods to recover the loss of cellular function due to mutations and other defects. Many approaches based on gene therapy aim to repair the defective gene or to insert genes with compensatory function. Here, we propose an alternative, network-based strategy that aims to restore biological function by forcing the cell to either bypass the functions affected by the defective gene, or to compensate for the lost function. Focusing on the metabolism of single-cell organisms, we computationally study mutants that lack an essential enzyme, and thus are unable to grow or have a significantly reduced growth rate. We show that several of these mutants can be turned into viable organisms through additional gene deletions that restore their growth rate. In a rather counterintuitive fashion, this is achieved via additional damage to the metabolic network. Using flux balance-based approaches, we identify a number of synthetically viable gene pairs, in which the removal of one enzyme-encoding gene results in a nonviable phenotype, while the deletion of a second enzyme-encoding gene rescues the organism. The systematic network-based identification of compensatory rescue effects may open new avenues for genetic interventions.

We present a detailed study of two-photon annihilation P \to γγand magnetic dipole transition V \to P γprocesses. The numerical predictions of the light-front approach are consistent with the experimental data and those in other approaches. The relations of the light-front approach with the other methods are discussed in brief.

title: Дуальные модели Лотмана и Милоша	– в анализах истории России и в автобиографии
Creators: name: Kaźmierczyk, Zbigniew
Publisher: name: AvtobiografiЯ

description: The author of the paper discusses the concept of alternation of predictable (symmetrical) and unpredictable (asymmetrical) occurrences under the influence of Prigogine’s theory of bifurcation. It shows that Lotman acknowleded those occurrences to be essential in historical processes, however, he considered the unpredictable occurrences to be destructive in developed cultures on the basis on the dual models on the account of the expectations of eschatological transformation of the world which they generate. At the same time, he hoped that the historical unpredictability would be connected with the transformation of the Russian cultural model.
The paper shows the application of dual models in Lotman’s cultural semiotics and Miłosz’s studies of Russia. It emphasizes that for Miłosz those were the models of Gnostic-Manichaean dualism and pictures him as a continuator of the Vilnius school of thought of Russia.

description: This article is devoted to characterize all possible effective behaviors of composite materials by means of periodic homogenization. This is known as a $G$-closure problem. Under convexity and $p$-growth conditions ($p>1$), it is proved that all such possible effective energy densities obtained by a $Γ$-convergence analysis, can be locally recovered by the pointwise limit of a sequence of periodic homogenized energy densities with prescribed volume fractions. A weaker locality result is also provided without any kind of convexity assumption and the zero level set of effective energy densities is characterized in terms of Young measures. A similar result is given for cell integrands which enables to propose new counter-examples to the validity of the cell formula in the nonconvex case and to the continuity of the determinant with respect to the two-scale convergence.

description: Η παρούσα εργασία στοχεύει στην ανάλυση μιας διάταξης δειγματοληψίας σωματιδιακών εκπομπών κινητήρων σε πραγματικό χρόνο. Η δειγματοληψία γίνεται με σταθερό λόγο αραίωσης και σταθερή θερμοκρασία αέρα αραίωσης, ώστε να ευνοείται η δημιουργία σωματιδίων από πυρογένεση. Στη διάταξη υπάρχει και προσροφητήρας πτητικών ουσιών για τη μέτρηση στερεών σωματιδίων. Στη διάταξη χρησιμοποιούνται όργανα που μετράνε σε πραγματικό χρόνο. Με βάση τα αποτελέσματα της εργασίας είναι δυνατό να μετρηθεί επαναλήψιμα και αντιπροσωπευτικά ως προς την ατμόσφαιρα τόσο η περιοχή συσσώρευσης, όσο και η πιο ασταθής γενικά περιοχή των πυρήνων. Η χρήση της διάταξης δειγματοληψίας με συγκεκριμένο πρωτόκολλο μέτρησης δίνει συγκρίσιμα αποτελέσματα για διαφορετικές τεχνολογίες κινητήρα, συσκευές μετεπεξεργασίας και καύσιμα, ακόμη και αν οι μετρήσεις έχουν διεξαχθεί σε διαφορετικά εργαστήρια
description: The present study aims on the development and evaluation of a sampling system for the measurement of vehicle exhaust particles in real time. A sampling system with constant sampling conditions that favors the formation of a discrete nucleation mode was chosen. A thermodenuder was also used for the measurement of solid particles. The final conclusion of this dissertation is that a partial flow sampling system operating under constant sampling conditions is capable of measurement airborne particle properties with a comparable repeatability to that of other lagislated pollutants. Nucleation mode particles should not be considered a sampling system artefact because they were also observed when sampling the exhaust phume chasing a diesel vehicle on an actual road. The sampling system developed is capable of repeating in the laboratory the potential for nucleation mode formation as measured in the chasing experiments

description: Combining robust magnetism, strong spin-orbit coupling and unique thickness-dependent properties of van der Waals crystals could enable new spintronics applications. Here, using density functional theory, we propose the (MnSb$_2$Te$_4$)$\cdot$(Sb$_2$Te$_3$)$_n$ family of stoichiometric van der Waals compounds that harbour multiple topologically-nontrivial magnetic phases. In the groundstate, the first three members of the family, i.e. MnSb$_2$Te$_4$, ($n=0$), MnSb$_4$Te$_7$, ($n=1$), and MnSb$_6$Te$_{10}$, ($n=2$), are 3D antiferromagnetic topological insulators (AFMTIs), while for $n \geq 3$ a special phase is formed, in which a nontrivial topological order coexists with a partial magnetic disorder in the system of the decoupled 2D ferromagnets, whose magnetizations point randomly along the third direction. Furthermore, due to a weak interlayer exchange coupling, these materials can be field-driven into the FM Weyl semimetal ($n=0$) or FM axion insulator states ($n \geq 1$). Finally, in two dimensions we reveal these systems to show intrinsic quantum anomalous Hall and AFM axion insulator states, as well as quantum Hall state, achieved under external magnetic field, but without Landau levels. Our results provide a solid computational proof that MnSb$_2$Te$_4$, is not topologically trivial as was previously believed that opens possibilities of realization of a wealth of topologically-nontrivial states in the (MnSb$_2$Te$_4$)$\cdot$(Sb$_2$Te$_3$)$_n$ family.

description: Spectral state transitions in neutron star LMXB systems have been widely observed yet not well understood. Here we report an abrupt spectral change in 4U 1608-52, a typical atoll source, during its decay phase of the 2004 outburst. The source is found to undergo sudden changes in its spectral hardness and other properties. The transition occurred when its luminosity is between (3.3-5.3) E36 ergs/s, assuming a distance of 3.6 kpc. Interpreting this event in terms of the propeller effect, we infer the neutron star surface magnetic field as (1.4-1.8) E8 Gauss. We also briefly discuss similarities and differences between the spectral states of neutron star and black hole binary systems.

We designed a one time fobt screening program on electronic protocol, in which we listed 8963 subjects over 50 years of age. From them 4189 were submitted 3-days fobt and the rest were our control group. In case of positive test(175), there was performed total colonoscopy. 17 polypoids and 20 cases of diverticulosis were detected. The compliance of FOBT group was 49%(from 4189). Our study shows acceptable compliance of screening population. There is need cooperation of local authorities
title: I Diari e la scrittura dell’ultimo Tolstoj. Una ricerca oltre il moralismo
Creators: name: Ghidini, Maria Candida

description: All his life Tolstoy has always written diaries. In his last thirty years, they have become so important that they have tinged his entire work, non-fiction as well as narrative. Originally a rational, planned practice of self-perfection, they evolved into an introspective reflection of the “I” and kept the trace of the tension to merge with a suprapersonal, universal dimension: the authentic, eternal I that does not know death. This essay aims to illustrate how Tolstoy's research cannot be reduced to a moralist and rationalist theory, as it has been often interpreted, especially by the Silver Age Russian religious thinkers. From the Diaries it is clear that the starting point for a deep reflection on the “I” is the experience of the limit and death. From here starts a new perception of the self, which, in order to preserve it, transcends it into a universal dimension that helps to overcome emptiness and lack of meaning. On a literary level this leads to a new type of writing and a new conception of authorship.

description: The effect of the spatially varying spin current on a skyrmion is numerically investigated. It is shown that an inhomogeneous current density induces an elongation of the skyrmion. This elongation can be controlled using current pulses of different strength and duration. Long current pulses lead to a splitting that forms two replicas of the initial skyrmion while for short pulses the elongated skyrmion relaxes back to its initial circular state through rotation in the MHz-GHz frequency range. The frequency is dependent on the strength of the damping coefficient.

Baryon deceleration by strong chromofields in ultrarelativistic nuclear collisions

Year: 2006
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: It is assumed that strong chromofields are generated at early stages of ultrarelativistic heavy-ion collisions which give rise to a collective deceleration of net baryons from colliding nuclei. We have solved classical equations of motion for baryonic slabs under the action of a time-dependent longitudinal chromoelectric field. It is demonstrated that the slab final rapidities are rather sensitive to the strength and decay time of the chromofield as well as to the back reaction of the produced partonic plasma. The net-baryon rapidity loss of about 2 units, found for most central Au-Au collisions at RHIC, can be explained by the action of chromofields with the initial energy density of about 50 GeV/fm^3. Predictions for the baryon stopping at the LHC are made.

description: Στόχος της έρευνας ήταν η διερεύνηση της επίδρασης των στενών διαπροσωπικών σχέσεων της μητέρας, της σχέσεις δηλαδή με το συντροφό της και τους ενήλικους φίλους της, στη δημοτικότητα και τις φιλίες παιδιών προεφηβικής και εφηβικής ηλικίας. Το δείγμα έρευνας αποτέλεσαν 270 παιδιά(Μ.Ο. ηλικίας, 13.6 έτη) προεφηβικής και εφηβικής ηλικίας και οι μητέρες τους. Στη συλλογή του ερευνητικού υλικού χρησιμοποιήθηκαν ερωτηματολόγια αυτοαναφοράς. Τα αποτελέσματα, μέσω πολλαπλών αναλύσεων παλινδρόμησης, έδειξαν ότι τόσο η σχέση της μητέρας με το συντροφό της όσο και με τους ενήλικες φίλους της προέβλεπαν τις φιλίες και τη δημοτικότητα των παιδιών. Η ενδογονεϊκή σύγκρουση ήταν αρνητικός προβλεπτικός παράγοντας της δημοτικότητας και όλων των ποιοτικών διαστάσεων των φιλιών των παιδιών, ενώ η ικανοποίηση της μητέρας από το γάμο της, οι φιλίες και το κοινωνικό της δίκτυο σχετίζονταν θετικά με τις φιλίες των παιδιών. Τα αποτελέσματα έδωσαν ακόμη εξελικτικές διαφορές : καθώς στις φιλίες και τη δημοτικότητα των παιδιών προεφηβικής ηλικίας οι παράγοντες πρόβλεψης ήταν περισσότεροι και ισχυρότεροι. Παρουσιάστηκαν τέλος διαφορές φύλου καθώς διαφορετικές εκφάνσεις της ενδογονεϊκής σύγκρουσης και των φιλιών της μητέρας προέβλεπαν τις φιλίες αγοριών και κοριτσιών
description: The aim of the present study was to explore the links between maternal interpersonal relationships, ie. marital relationship and freindships and childrens close friendships and peer group acceptance. 270 children (mean age 13.6 yrs), predolescents and adolescents took part in the study. Self report meassures were used in data collection. Results through the application of muptiple regression analyses, indicated that childrens peer group acceptance, and friendship quality was influenced by the quality of their mother's friendships, social network and marital relationship. Interparental conflict was a negative predictor of children's fiendship qualities, where as marital satisfaction, maternal friendships and social network predicted positively children's friendship. Age differences were also present, since results indicated that predictors gender differences : although interparental conflict and maternal friendship had an effect on both boy's and girls' friendship, different appraisals of these relationships predicted children's friendship qualities
