description: Weyl points are point degeneracies that occur in momentum space of periodic materials, and are associated with a quantized topological charge. We experimentally observe in a 3D micro-printed photonic crystal that a charge-2 Weyl point can be split into two charge-1 Weyl points as the protecting symmetry of the original charge-2 Weyl point is broken. Moreover, we use a theoretical analysis to confirm where the charge-1 Weyl points move within the Brillouin zone as the strength of the symmetry breaking increases, and confirm it in experiments using Fourier-transform infrared spectrometry. This micro-scale observation and control of Weyl points is important for realizing robust topological devices in the near-infrared.
Quantum statistics of Schrödinger cat states prepared by logical gate with non-Gaussian resource state

description: A measurement-induced continuous-variable logical gate is able to prepare Schrödinger cat states if the gate uses a non-Gaussian resource state, such as cubic phase state [I. V. Sokolov, Phys. Lett. A 384, 126762 (2020)]. Our scheme provides an alternative to hybrid circuits which use photon subtraction and (or) Fock resource states and photon number detectors. We reveal the conditions under which the gate conditionally prepares quantum superposition of two undistorted "copies" of an arbitrary input state that occupies a finite area in phase space. A detailed analysis of the fidelity between the gate output state and high-quality Schrödinger cat state is performed. A clear interpretation of the output state quantum statistics in terms of Wigner function in dependence on the gate parameters and measurement outcome is presented for a representative set of input Fock states.

description: An analysis is given of the Stueckelberg extension of the Standard Model with a hidden sector gauge group $U(1)_X$ where the mass growth for the extra gauge boson occurs via the Stueckelberg mechanism, and where the kinetic mixing in the $U(1)_X\times U(1)_Y$ sector is included. Such a kinetic mixing is generic in a broad class of supergravity and string models. We carry out a detailed global fit of the model with the precision LEP data on and off the $Z$ pole, with $χ^2$ within 1% of the $χ^2$ of the Standard Model fit. Further, it is shown that in the absence of matter in the hidden sector, there is a single effective parameter that controls the deviations from the Standard Model predictions, and the dependence on the kinetic mixing emerges only when matter in the hidden sector is included. An analysis is also given of milli-charged dark matter arising from the hidden sector, where it is shown that such dark matter from the Stueckelberg extension can satisfy WMAP-3 data while allowing for a sharp $Z'$ resonance which can be detected at the Tevatron and at the LHC via a dilepton signal generated by the Drell-Yan process.

description: "The invariants and covariants of a quaternary system of a linear complex and a quadric have been discussed by Weitzenbock, but he excludes the mixed concomitants. In the present paper the concomitants (which will include mixed forms) of a quadric and two linear complexes are discussed. The Reduced Prepared System is given in §3, the Complete System in §8 and some invariants of the covariant forms in §9. The concomitants of a quadric and 𝑛 linear complexes have next been considered and the corresponding reduced system of typical forms, is given at the end of the paper." -- From the Introduction.
A kinematic model for collision response
Creators: name: Harrison, Jason
Publisher: name: University of British Columbia
Year: 2009

description: Over the course of several years, an informal poll by Dave Forsey of commercial animators revealed that the single most useful tool to add to a computer animation system would be a way to control the simple act of pressing one object into another. This ability would dras tically increase the range and style of animations that could be created within a production environment. This thesis presents a simple, fast, geometric approach to controlling the nature, extent and timing of the surface deformations arising from the interpenetration of kinematically controlled animated objects. Rather than using dynamic simulations, which are difficult to configure, code, and control, the algorithm presented here is based upon the idea that collision response is a matter of moving specific points on the surface towards specific goal points at a certain rate. This is an operation similar to manipulating chains of rigid bodies using inverse kinematics. This formulation is easily extendable to free-form surface modeling where generally oniy one point, or possibly more, is manipulated interactively at a time. We use a multi-resolution approach to deformations to provide control over the response of the surface using a small number of parameters. Each of the parameters determine how a level in the multi-resolution representation of the surface reacts to the interpenetration. The deformations are calculated in time and space proportional to the number of points used to define the surface.

Αρχικά, εξετάστηκε η υποχρέωση πίστης του εργαζομένου κατά τη διάρκεια της σύμβασης εργασίας, καθώς και η αμφιλεγόμενη θέση περί μετενέργειας. Στη συνέχεια, παρουσιάστηκαν οι έννοιες της μετασυμβατικής απαγόρευσης ανταγωνισμού και εχεμύθειας, και αναφέρθηκαν οι ομοιότητες και οι διαφορές τους, καθώς και ο ρόλος που αυτές οι ρήτρες επιτελούν. Προχωρώντας, εξετάσθηκαν οι επιμέρους προϋποθέσεις εγκυρότητας των εν λόγω ρητρών, όπως έχουν διαπλαστεί από τη νομολογία και τη θεωρία. Συναφώς, έγινε εκτενής αναφορά στον έλεγχο της νομιμότητας των ρητρών, όπως διενεργείται σήμερα από τη νομολογία, αλλά και στις αντιρρήσεις που έχουν διατυπωθεί από μέρος της θεωρίας αναφορικά με την αποτελεσματικότητα του ως άνω δικαστικού ελέγχου και που προτάσσουν την διενέργειά του στη βάση άλλων διατάξεων (281 ΑΚ, Ν. 2251/1994).

Τέλος, εξετάστηκαν ορισμένα ειδικότερα ζητήματα σε σχέση με αυτήν την θεματική, όπως είναι οι ρήτρες υπό αίρεση, οι ρήτρες σε περίπτωση μεταβίβασης επιχείρησης και οι ρήτρες ως αντικείμενο συλλογικής σύμβασης εργασίας
description: The aim of the present thesis was the study of confidentiality and non-competition clauses after the expiration of the employment contract. At first, employee’s duty of loyalty during the employment contract was examined, as well as the controversial issue of the continuance of this duty after the expiration of the employment contract, whether or not is agreed between the parties. Then, the meaning of non-competition and confidentiality clauses was presented, as well as their similarities and differences and the purpose that is aimed by concluding them. Furthermore, the legal requirements of the clauses were examined. In that connection, we examined the way that Greek courts view the legality of the clauses today, and in addition to that, the opposite position of part of the theory, that supports other opinions. The consequences of invalid clauses are also examined, as well as the claims that employer has,, in case that a valid clause is being violated by the employee. Finally, some specific issues regarding the above clauses were examined too

description: Quantum teleportation, a way to transfer the state of a quantum system from one location to another, is central to quantum communication and plays an important role in a number of quantum computation protocols. Previous experimental demonstrations have been implemented with photonic or ionic qubits. Very recently long-distance teleportation and open-destination teleportation have also been realized. Until now, previous experiments have only been able to teleport single qubits. However, since teleportation of single qubits is insufficient for a large-scale realization of quantum communication and computation2-5, teleportation of a composite system containing two or more qubits has been seen as a long-standing goal in quantum information science. Here, we present the experimental realization of quantum teleportation of a two-qubit composite system. In the experiment, we develop and exploit a six-photon interferometer to teleport an arbitrary polarization state of two photons. The observed teleportation fidelities for different initial states are all well beyond the state estimation limit of 0.40 for a two-qubit system. Not only does our six-photon interferometer provide an important step towards teleportation of a complex system, it will also enable future experimental investigations on a number of fundamental quantum communication and computation protocols such as multi-stage realization of quantum-relay, fault-tolerant quantum computation, universal quantum error-correction and one-way quantum computation.

description: The article presents a non-traditional approach to evaluation of Japan’s soft power in the context of its humanitarian cooperation with East Asian states (primarily, China and South Korea) and also Russia. The characteristic features of current Japan’s soft power and the historic prerequisites for the development the Japanese foreign policy of this sphere are analyzed. In the author’s opinion, there is no alternative of Japan’s soft power to hard power currently employed by other countries of East Asia. The article stresses the successes of Japanese policy of simulating the inflow of foreign tourism and analyzes the reasons for the steady growth in the number of tourists arriving in Japan. Recent statistics shows the predominance of Chinese and South Koreans among foreign guests, both tourists and expats, with the mostly negative attitude to China and South Korea among the Japanese citizens. The deterioration of the demographic situation in Japan is also marked: the percentage of foreigners is growing, which prompts the Japanese to adjust. The article highlights humanitarian cooperation between Japan and Russia in the Cross-year Year of 2018, which was initiated by the country’s leaders to boost contacts in a broad range of areas. It indicates a decline in the bilateral trade in the past five years and points a low level of mutual tourism. There are different reasons for Russia and Japan for insignificant number of tourists travelling to the partner country. The antipathy of most Japanese toward Russia is a negative factor for bilateral relations. In conclusion, the author elaborates on the possible ways of enhancing the Russo-Japanese relations in the context of the highlighted issues. The article’s objective is to inform experts working in relevant areas about successful Japanese projects with the aim of borrowing some useful Japanese practices of soft power and outbound tourism in relations with other countries. This experience could be beneficial for Russia.

description: Estimating high quantiles plays an important role in the context of risk management. This involves extrapolation of an unknown distribution function. In this paper we propose three methods, namely, the normal approximation method, the likelihood ratio method and the data tilting method, to construct confidence regions for high quantiles of a heavy tailed distribution. A simulation study prefers the data tilting method.

description: The main problems of political socialization of Japanese youth are studied in the paper. According to the author’s point of view, participation in the election process, youth movements, and a growing interest in international issues are the principal trends and the main indicators of Japanese youth’s political activity and political socialization of young people in contemporary Japanese society. Political socialization is the transmission of political culture to new generations of citizens in a given society and it includes such activities as voting campaigns, attending meetings, joining political parties, taking part in political discussions, еtс. Whether young people have ability to quickly adapt to the changing circumstances of the world around them depends on the process of political socialization. The difficulties that characterize the Japanese youth’s political socialization process during the last decade and its outcomes have become especially evident now young people exhibit a less developed sense of civic duty, and take the obligations of citizenship more lightly than older generations. One of the factors influencing young people’s tendency to be engaged in civic and political activities may be the fact that the traditional mobilizing institutions of politics in Japan are not especially interested in reaching out to young people. In the article the main problems of political socialization of Japanese youth are examined. Using the data from large-scale surveys of Pew Research Center and some data of Mainichi Shimbun surveys carried out in 2017, the author analyzes whether young Japanese people are active participants of political process or play the role of unconcerned spectators.

description: We consider the classical response in a chaotic system. In contrast to behavior in integrable or almost integrable systems, the nonlinear classical response in a chaotic system vanishes at long times. The response also reveals certain features of collective resonances which do not correspond to any periodic classical trajectories. The convergence of the response is shown to hold due to the exponential time dependence of the stability matrix. The growing exponentials corresponding to strong instability do not inhibit the convergence. We calculate both linear and second-order response in one of the simplest chaotic systems: free classical motion on a surface of constant negative curvature. We demonstrate the relevance of the model for applications to spectroscopic experiments.

Γεννήθηκε το 1846 στη Σηλυβρία της Ανατολικής Θράκης, υπήρξε λαοφιλής ιεράρχης, παιδαγωγός, διευθυντής της Ριζαρείου Εκκλησιαστικής Σχολής και ιδρυτής της Ιεράς Μονής Αγίας Τριάδος στην Αίγινα. Ο Άγιος Νεκτάριος αποτέλεσε πρότυπο παιδαγωγού και συνέβαλε στην ηθική και θρησκευτική αφύπνιση του πληρώματος της Εκκλησίας. Ως έφηβος καθώς εργαζόταν σκληρά σε μια αποθήκη καπνών στην Κωνσταντινούπολη μελετούσε συγγράμματα των Πατέρων της Εκκλησίας και των κλασικών φιλοσόφων, καταγράφοντας όσα από τα αποφθέγματά τους του φαίνονταν ψυχωφελή σε χαρτιά συσκευασίας καπνών. Κατ’ αυτόν τον τρόπο, συγκέντρωσε το υλικό για το βιβλίο του , Ιερών και φιλοσοφικών λογίων θησαύρισμα, το οποίο εξέδωσε το 1895. Εκοιμήθη το 1920 στην Αθήνα και έχει οριστεί «Προστάτης όλων των Εκκλησιαστικών Σχολείων και Σχολών της Ελλάδος»
description: Saint Nectarios, who was consecrated Bishop of Pentapolis in Libya, is a contemporary saint of Church. Born in 1846 in Selybria, in the east of Thrace, he was a hierarch beloved by the people, an educator, a director of the Rizario Ecclesiastic Faculty and a founder of the Holy Trinity Monastery in Aegina. Saint Nectarios became a model educator and contributed to the moral and religious awakening of Christian Community. As a teenager, while working hard in a tobacco warehouse in Constantinople, he would study writings of the Church Fathers and the classical philosophers, writing down on tobacco packaging paper many maxims which he deemed useful to the soul. Thus he gleaned the material for his book Sacred and Philosophical Scholars’ Treasures, issued in 1895. He reposed in the Lord, in Athens, in 1920, and he is now recognized as ‘Protector of all the Ecclesiastic Schools and Faculties of Greece’

We subject these systems to a non-anticommutative deformation by replacing the Grassmann algebra of the odd superspace coordinates with a Clifford algebra. Static CP^1 and scattering U(2) solitons are constructed and carry an additional spin-1/2 degree of freedom due to the deformation. Abelian BPS solutions exist as well but have infinite action, in contrast to the Moyal case.

description: Several monolayer transition metal dichalcogenides (TMDs) are direct band gap semiconductors and potentially efficient emitters in light emitting devices. Photons are emitted when strongly bound excitons decay radiatively, and accurate models of such excitons are important for a full understanding of the emission. Importantly, photons are emitted in directions uniquely determined by the exciton center of mass momentum and with lifetimes determined by the exciton transition matrix element. The exciton band structures of two-dimensional hexagonal materials, including TMDs, are highly unusual with coexisting particle- and light-like bands. The latter is non-analytic with emission selection rules essentially opposite to the particle-like states, but has been ignored in analyses of TMD light emission so far. In the present work, we analyse the temperature and angular dependence of light emission from both exciton species and point out several important consequences of the unique exciton band structure. Within a first-principles Density-Functional-Theory+Bethe-Salpeter-Equation framework, we compute exciton band structures and optical matrix elements for the important TMDs MoS2, MoSe2, WS2, and WSe2. At low temperature, only the particle-like band is populated and our results agree with previous work. However, at slightly elevated temperatures, a significant population of the light-like band leads to modified angular emission patterns and lifetimes. Clear experimental fingerprints are predicted and explained by a simple four-state model incorporating spin-orbit as well as intervalley exchange coupling.

Η μητέρα Εκκλησία αποδέχτηκε το αίτημα αυτό (1998), εκδίδοντας Πατριαρχικό και Συνοδικό Τόμο μέσω του οποίου παραχωρήθηκε πλήρης εκκλησιαστική ανεξαρτησία στην εν λόγω Εκκλησία με βάση την κανονική τάξη και παράδοση της Ορθόδοξης Εκκλησίας.

However, Churches of Serbia and Russia tried to extend non-canonical their ecclesiastical jurisdictions. Therefore, in this case held illegal and irregular manipulation of a Church by other Churches with final result that Czechoslovakian Church received supposedly autocephality (1951). Then, Church of Czech lands and Slovakia submitted a request of declaration of autocephalon to the Ecumenical Patriarchate, ignoring and in fact denouncing the un-canonical Russian one. Mother Church accepted the request by sending Patriarchal and Synodical Tomos (1998) through which granted full ecclesiastical independence, according to all requirements arising from the Divine and Sacred canons. Only at this point Czech and Slovak Orthodox Church recognized as Autocephalous by the whole Christian World and took the 14 place after Church of Albania

description: Magneto-optical imaging was used to observe flux dendrites with opposite polarities simultaneously penetrate superconducting, ring-shaped MgB$_2$ films. By applying a perpendicular magnetic field, branching dendritic structures nucleate at the outer edge and abruptly propagate deep into the rings. When these structures reach close to the inner edge, where flux with opposite polarity has penetrated the superconductor, they occasionally trigger anti-flux dendrites. These anti-dendrites do not branch, but instead trace the triggering dendrite in the backward direction. Two trigger mechanisms, a non-local magnetic and a local thermal, are considered as possible explanations for this unexpected behaviour. Increasing the applied field further, the rings are perforated by dendrites which carry flux to the center hole. Repeated perforations lead to a reversed field profile and new features of dendrite activity when the applied field is subsequently reduced.

description: In a series of papers, Saxena, Mathai, and Haubold (2002, 2004a, 2004b) derived solutions of a number of fractional kinetic equations in terms of generalized Mittag-Leffler functions which provide the extension of the work of Haubold and Mathai (1995, 2000). The subject of the present paper is to investigate the solution of a fractional reaction-diffusion equation. The results derived are of general nature and include the results reported earlier by many authors, notably by Jespersen, Metzler, and Fogedby (1999) for anomalous diffusion and del-Castillo-Negrete, Carreras, and Lynch (2003) for reaction-diffusion systems with Lévy flights. The solution has been developed in terms of the H-function in a compact form with the help of Laplace and Fourier transforms. Most of the results obtained are in a form suitable for numerical computation.

From random point processes to hierarchical Cavity Master Equations for the stochastic dynamics of disordered systems in Random Graphs: Ising models and epidemics

description: We start from the Theory of Random Point Processes to derive n-point coupled master equations describing the continuous dynamics of discrete variables in random graphs. These equations constitute a hierarchical set of approximations that generalize and improve the Cavity Master Equation (CME) recently obtained in other publications. Our derivation clarifies some of the hypotheses and approximations that originally lead to the CME, considered now as the first order of a more general technique. We tested the new scheme in the dynamics of three models defined over diluted graphs: the Ising ferromagnet, the Viana-Bray spin-glass and the susceptible-infectious-susceptible model for epidemics. In the first two, the new equations perform similarly to the best-known approaches in the literature. In the latter, they outperform the well-known Pair Quenched Mean-Field Approximation.

description: The main scientific goal of the Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM) is to monitor various types of Gamma-Ray Bursts (GRB) originated from merger of binary compact stars, which could also produce gravitational wave, and collapse of massive stars. In order to study the response of GECAM Gamma-Ray Detectors (GRDs) to high-energy bursts and test the in-flight trigger and localization software of GECAM before the launch, a portable GRB simulator device is designed and implemented based on grid controlled X-ray tube (GCXT) and direct digital synthesis (DDS) technologies. The design of this GRB simulator which modulates X-ray flux powered by high voltage up to 20 kV is demonstrated, and the time jitter (FWHM) of the device is about 0.9 $μ$s. Before the launch in December, 2020, both two GECAM satellites were irradiated by different types of GRBs (including short and long bursts in duration) generated by this GRB simulator. The light curves detected with GECAM/GRDs are consistent with the programmed input functions within statistical uncertainties, indicating the good performance of both the GRDs and the GRB simulator.

Gas expulsion and the destruction of massive young clusters

description: We examine the luminosity and dynamical mass estimates for young massive stellar clusters. For many young (<50 Myr) clusters, the luminosity and dynamical mass estimates differ by a significant amount. We explain this as being due to many young clusters being out of virial equilibrium (which is assumed in dynamical mass estimates) because the clusters are undergoing violent relaxation after expelling gas not used in star formation. We show that, if we assume that luminous mass estimates are correct (for a standard IMF), at least 50 per cent of young clusters for which dynamical masses are known are likely to be destroyed within a few 10s Myr of their formation. Even clusters which will retain a bound core may lose a large fraction of their stellar mass. We also show that the core radius and other structural parameters change significantly during the violent relaxation that follows gas expulsion and that they should be considered instantaneous values only, not necessarily reflecting the final state of the cluster. In particular we note that the increasing core radii observed in young LMC/SMC clusters can be well explained as an effect of rapid gas loss.

description: We propose a novel approach to select privacy-sensitive IaaS providers for a long-term period. The proposed approach leverages a consumer's short-term trial experiences for long-term selection. We design a novel equivalence partitioning based trial strategy to discover the temporal and unknown QoS performance variability of an IaaS provider. The consumer's long-term workloads are partitioned into multiple Virtual Machines in the short-term trial. We propose a performance fingerprint matching approach to ascertain the confidence of the consumer's trial experience. A trial experience transformation method is proposed to estimate the actual long-term performance of the provider. Experimental results with real-world datasets demonstrate the efficiency of the proposed approach.

Discovery of correlated evolution in solar noise storm source parameters: Insights on magnetic field dynamics during a microflare
Creators: name: Mohan, Atul
Publisher: name: arXiv
Year: 2021
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: A solar type-I noise storm is produced by accelerated particle beams generated at active regions undergoing magnetic field restructuring. Their intensity varies by orders of magnitude within sub-second and sub-MHz scales. But, the morphological evolution of these sources are not studied at these scales, due to the lack of required imaging cadence and fidelity in metrewave bands. Using data from the Murchison Widefield Array (MWA), this work explores the co-evolution of size, sky-orientation and intensity of a noise storm source associated with a weak microflare. The work presents the discovery of two correlated modes of evolution in the source parameters: a sausage like \s\ mode where the source intensity and size shows an anti-correlated evolution; and a torsional like \T\ mode where the source size and sky-orientation shows a correlated evolution. A flare mediated mode conversion is observed from \T\ to \s\ for the first time in these sources. These results support the idea of build up of magnetic stress energy in braided active region loops, which later go unstable causing flares and particle acceleration until they relax to a minimally braided state. The discovered mode conversion can be a future diagnostic to such active region phenomena.
