description: The quantum spin Hall state is a topologically non-trivial insulator state protected by the time reversal symmetry. We show that such a state always leads to spin-charge separation in the presence of a $π$ flux. Our result is generally valid for any interacting system. We present a proposal to experimentally observe the phenomenon of spin-charge separation in the recently discovered quantum spin Hall system.

description: Επειδή υπάρχει έλλειψη πιστοποιημένου υλικού αναφοράς (CRM) για την καταλυτική δραστικότητα της λιπάσης η μεταξύ των μεθόδων δυνατότητα σύγκρισης είναι αρκετά αναξιόπιστη. Ο στόχος αυτής της μελέτης ήταν να παραχθούν δυο λιπάσες (CRMs), μια από ανθρώπινο παγκρεατικό υγρό (BCR 693), και μια άλλη χρησιμοποιώντας τεχνολογίες ανασυνδυασμένου DNA (BCR 694). Η ανθρώπινη παγκρεατική λιπάση καθαρίστηκε από παγκρεατικό υγρό, χρησιμοποιώντας στήλη χρωματογραφίας και ισοηλεκτρική εστίαση. Η ανασυνδυασμένη παγκρεατική λιπάση παρήχθη από επιμολυσμένη σειρά κύτταρων και καθαρίστηκε σε στήλη χρωματογραφίας. Προσθέτοντας ρυθμιστικό διάλυμα ορού αλβουμίνης από βοοειδή, επακολούθησε καταψυκτική ξήρανση (εξάχνωση) για την σταθεροποίηση των δυο υλικών. Μια τυποποιημένη μέθοδος τιτλοδότησης χρησιμοποιήθηκε για να συγκρίνει τις καταλυτικές ιδιότητες δυο συγκεντρωτικών δειγμάτων από πλάσμα ασθενών με οξεία παγκρεατίτιδα. Περίπου 5 kU (τιτλοδότηση, 37 ° C) για κάθε υλικό ελήφθησαν. Μετά την λυοφιλίωση δεν υπήρχαν προφανείς τροποποιήσεις των καταλυτικών ιδιοτήτων τους, οι οποίες έμειναν ταυτόσημες με εκείνες που παρουσιάζει το ένζυμο στο συγκεντρωτικό δείγμα των ασθενών. Η σταθερότητα των δυο υλικών υπολογίζεται σε αρκετά χρόνια, όταν αποθηκεύονται σε ξηρή μορφή στους -20 °C. Και τα δυο υλικά φαίνεται να έχουν παρόμοιες καταλυτικές ιδιότητες και σταθερότητα και μπορούν να υποκαταστήσουν τόσο μια μέθοδο αναφοράς όσο και μια διαδικασία μέτρησης ρουτίνας. Οργανώθηκε λοιπόν, μια διεθνής συντονισμένη διαδικασία πιστοποίησης με σκοπό να ορίσει τιμές στα υλικά αναφοράς BCR 693 και BCR 694. Σε αυτή τη διαδικασία συμμετείχε και η δική μας ερευνητική ομάδα στο εργαστήριο βιοχημείας όπου και εκπονήθηκε η συγκεκριμένη εργασία.

Unusual Scaling of Kondo Spin Relaxation

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

description: The relation between the Kondo spin relaxation rate $ {τ_{sK}}^{-1} $ and the Kondo momentum relaxation rate $ {τ_{eK}}^{-1} $ is explored by using nonlocal spin valves with submicron copper channels that contain dilute iron impurities. A linear relation between $ {τ_{sK}}^{-1} $ and $ {τ_{eK}}^{-1} $ is established under varying temperatures. However, under varying impurity concentrations, ${τ_{sK}}^{-1}$ remains nearly constant despite variation of $ {τ_{eK}}^{-1} $ by a factor of 10. This surprising relation can be understood by considering spin relaxation through overlapping Kondo screening clouds and supports the physical existence of the elusive Kondo clouds.

description: From a 'discrete' functional zero curvature equation, functional representations of (matrix) Burgers and potential KP (pKP) hierarchies (and others), as well as corresponding Backlund transformations, can be obtained in a surprisingly simple way. With their help we show that any solution of a Burgers hierarchy is also a solution of the pKP hierarchy. Moreover, the pKP hierarchy can be expressed in the form of an inhomogeneous Burgers hierarchy. In particular, this leads to an extension of the Cole-Hopf transformation to the pKP hierarchy. Furthermore, these hierarchies are solved by the solutions of certain functional Riccati equations.

description: This report is the diplomatic study on the subject “Management of Commercial Ports”, which was written during the postgraduate program “Construction management” of the department of Civil Engineers, Aristotle University of Thessaloniki.New conditions that emanate from the globalisation of trade, affected also in port industry. The ports are critical nodes in the world chain of transports, so the competition in the market of port industry have been increased and at the same time requirements on port services were also increased. So, port management concerns mainly, the attendance of private sector in the operation of port. Objective of study is to give essential information on the methods which are applied in these cases.In this study, initially are presented general issues that concern ports, like their history, their characteristics and the general tendency that prevails for their role in the World but also National economy and Trade. There are contained various methods of privatisations with description and their characteristics, advantages and disadvantages are presented. Also in this study statistical data regarding indexes of port performance before and after privatisation are presented. Same data of ports of Thessaloniki and Piraeus are presented and they show their performance and their status regarding the other ports of Mediterranean see. Finally conclusions and proposals concerning port management and privatization are presented in the last chapter of this study.

description: This paper presents an economic analysis of the intensity and the trade potential between Turkey and the ECOWAS countries. Using the trade intensity, the trade complementarity and the revealed comparative advantage indexes, the results indicate that Ghana, Burkina Faso, and Togo have high export proportions towards Turkey while Benin, the Gambia, Ghana, Guinea, Senegal, and Togo are increasingly using Turkey as a source of imports. Ghana appears to be the country with the most integrated trade relationship with Turkey compared to other countries in the region. Turkey has a comparative advantage over most of the ECOWAS countries in foodstuffs, textiles, metals, miscellaneous, and plastic and rubber. The trade complementarity index shows that a trade agreement would be ideal between Turkey, Ghana, and Guinea but such an agreement would not be viable for Liberia and Mali, while the results are less conclusive for the remaining of countries. In light of these results, we emphasize that trade potentials exist between Turkey and ECOWAS, notably in the processed food sector, textile, and cotton processing plants, and for an effective trade agreement implementation, individual characteristics of each ECOWAS country need to be taken into account.

description: Low-symmetry 2D materials---such as ReS$_2$ and ReSe$_2$ monolayers, black phosphorus monolayers, group-IV monochalcogenide monolayers, borophene, among others---have more complex atomistic structures than the honeycomb lattices of graphene, hexagonal boron nitride, and transition metal dichalcogenides. The reduced symmetries of these emerging materials give rise to inhomogeneous electron, optical, valley, and spin responses, as well as entirely new properties such as ferroelasticity, ferroelectricity, magnetism, spin-wave phenomena, large nonlinear optical properties, photogalvanic effects, and superconductivity. Novel electronic topological properties, nonlinear elastic properties, and structural phase transformations can also take place due to low symmetry. The "Beyond Graphene: Low-Symmetry and Anisotropic 2D Materials" Special Topic was assembled to highlight recent experimental and theoretical research on these emerging materials.

It also touches on nucleon studies, emphasising the importance of both scalar and axial-vector diquark correlations, and reporting the calculation of mu_n G_E^n(Q^2)/G_M^n(Q^2). The value of respecting symmetries, including Poincare' covariance, is stressed.

Network inference is a subfield of systems biology devoted to the identification of biochemical networks from experimental data. Common to both areas of research is their focus on the maximization of information gathered from experimentation. The goal of this paper is to establish a connection between these two areas coming from the common use of polynomial models and techniques from computational algebra.

Interactive topological drawing
Creators: name: Scharein, Robert Glenn
Publisher: name: University of British Columbia
Year: 2009

description: The research presented here examines topological drawing, a new mode of constructing and interacting with mathematical objects in three-dimensional space. In topological drawing, issues such as adjacency and connectedness, which are topological in nature, take precedence over purely geometric issues. Because the domain of application is mathematics, topological drawing is also concerned with the correct representation and display of these objects on a computer. By correctness we mean that the essential topological features of objects are maintained during interaction. We have chosen to limit the scope of topological drawing to knot theory, a domain that consists essentially of one class of object (embedded circles in three-dimensional space) yet is rich enough to contain a wide variety of difficult problems of research interest. In knot theory, two embedded circles (knots) are considered equivalent if one may be smoothly deformed into the other without any cuts or self-intersections. This notion of equivalence may be thought of as the heart of knot theory. We present methods for the computer construction and interactive manipulation of a wide variety of knots. Many of these constructions would be difficult using standard computeraided drawing methods. Interactive techniques allow for knot simplification under topological constraints from complicated conformations to simpler embeddings. These methods have proven useful in the investigation of the knot equivalence problem. As a further test of its utility, topological drawing has been used for several knot theoretical applications. The first of these involves finding the stick-number of a knot (the fewest number of straight sticks needed to form the knot). A second application is to the relaxation of knots under a physically-based knot energy (the symmetric energy) that we find effectively simplifies knots to configurations approaching their "canonical form". Finally, our methods have proven useful in the visualization of a class of knots that arise in a study of three-manifold topology. These knots often have complex descriptions (for example, as a huge braid word), but may be simplified greatly through the use of interactive topological drawing. Here, an expert user relies on the visualization in order to steer the computation in a direction that will often significantly improve performance.
Spin-memory loss induced by bulk spin-orbit coupling at ferromagnet/heavy-metal interfaces

description: A spin current through a ferromagnet/heavy-metal interface may shrink due to the spin-flip at the interface, resulting in the spin-memory loss. Here we propose a mechanism of the spin-memory loss. In contrast to other mechanisms based on interfacial spin-orbit coupling, our mechanism is based on the bulk spin-orbit coupling in a heavy-metal. We demonstrate that the bulk spin-orbit coupling induces the entanglement between the spin and orbital degrees of freedom and this spin-orbital entanglement can give rise to sizable spin-flip at the interface even when the interfacial spin-orbit coupling is weak. Our mechanism emphasizes crucial roles of the atomic orbital degree of freedom and induces the strong spin-memory loss near band crossing points between bands of different orbital characters.

Orbital Variational Adiabatic Hyperspherical Method Applied to Bose-Einstein Condensates
Creators: name: Lee, Hyunwoo
name: Greene, Chris H.
Publisher: name: arXiv
Year: 2020
Subjects: subject: Atomic Physics (physics.atom-ph)

description: A variational basis set motivated by mean-field theory is utilized to describe the Bose-Einstein condensate within the adiabatic hyperspherical coordinate framework. The simplest single-orbital variant of this treatment reproduces many of the ground state properties predicted by the Gross-Pitaevskii equation. But a multi-orbital improvement to the basis set yields a better representation of particle correlations and of the critical number where the condensate collapses for a negative two-body scattering length. The method also produces systematic deviations from Bogoliubov theory for the fundamental monopole excitation frequency.

description: We have devised an experimentally realizable model generating twin beam states whose individual beam photon statistics are varied from thermal to Poissonian keeping the non-classical mode correlation intact. We have studied the usefulness of these states for loss measurement by considering three different estimators, comparing with the correlated thermal twin beam states generated from spontaneous parametric down conversion or four-wave mixing. We then incorporated the photon subtraction operation into the model and demonstrate their advantage in loss estimations with respect to un-subtracted states at both fixed squeezing and per photon exposure of the absorbing sample. For instance, at fixed squeezing, for two photon subtraction, up to three times advantage is found. In the latter case, albeit the advantage due to photon subtraction mostly subsides in standard regime, an unexpected result is that in some operating regimes the photon subtraction scheme can also give up to 20% advantage over the correlated Poisson beam result. We have also made a comparative study of these estimators for finding the best measurement for loss estimations. We present results for all the values of the model parameters changing the statistics of twin beam states from thermal to Poissonian.

description: In life, individuals have rights and responsibilities from birth to death. After death, they lose legal personhood and become possessions, with concerns extending to their body, reputation, and estate. While ownership of property ends, the law recognizes three posthumous rights: dignified burial or cremation, execution of the will, and preservation of reputation. Criminal law prohibits desecration of the body. Despite not being legal persons, the legal system respects their testamentary wishes, allowing the establishment of trusts for graveyard upkeep. However, individuals can't permanently allocate estate parts for personal grave maintenance. Lifetime bequests of body parts are restricted, but eye donation is legally permissible.

description: We investigate the current-induced spin polarization in the two-dimensional hole gas (2DHG) with the structure inversion asymmetry. By using the perturbation theory, we re-derive the effective $k$-cubic Rashba Hamiltonian for 2DHG and the generalized spin operators accordingly. Then based on the linear response theory we calculate the current-induced spin polarization both analytically and numerically with the disorder effect considered. We have found that, quite different from the two-dimensional electron gas, the spin polarization in 2DHG depends linearly on Fermi energy in the low doping regime, and with increasing Fermi energy, the spin polarization may be suppressed and even changes its sign. We predict a pronounced peak of the spin polarization in 2DHG once the Fermi level is somewhere between minimum points of two spin-split branches of the lowest light-hole subband. We discuss the possibility of measurements in experiments as regards the temperature and the width of quantum wells.

description: Three basic factors govern the individual behaviour of a particle: the inertia from its previous displacement; the attraction to its own best experience; and the attraction to a given neighbour's best experience. The importance awarded to each factor is controlled by three coefficients: the inertia; the individuality; and the sociality weights. The social behaviour is ruled by the structure of the social network, which defines the neighbours that are to inform of their experiences to a given particle. This paper presents a study of the influence of different settings of the coefficients as well as of the combined effect of different settings and different neighbourhood topologies on the speed and form of convergence.

description: Η εν λόγω εργασία αφορά στη μελέτη ενός περιορισμένου αριθμού άρθρων της στήλης «Ρεπορτάζ» της κυριακάτικης ελληνικής εφημερίδας «Το Βήμα», όπως αυτά δημοσιεύτηκαν την περίοδο 2000-2006. Στόχος ήταν η ανίχνευση των ποικίλων στρατηγικών λόγου και γλωσσικών μέσων που είναι δυνατόν, άλλοτε περισσότερο και άλλοτε λιγότερο, να συμβάλλουν στην αναπαραγωγή στερεοτύπων και προκαταλήψεων για τις ομάδες μειονότητας. Η ανάλυση στηρίχτηκε στις μεθόδους της κριτικής ανάλυσης λόγου όπως αυτή εφαρμόστηκε από τον Teun A. Van Dijk (1991). Η αδιαμφισβήτητη δύναμη του Τύπου και η ικανότητα του να διαμορφώνει στάσεις, ιδεολογίες και συμπεριφορές, χρησιμοποιώντας το πανίσχυρο εργαλείο της γλώσσας, στάθηκε η αφορμή για την επιλογή του θέματος αυτού του συγγράμματος.
description: The particular paper involves the study of a limited number of articles from the Greek Sunday newspaper “Vima”, as these were published, under the column “Reportage”, during the period of 2000-2006. Its main objective is to trace the various strategies of discourse and linguistic tools that may potentially contribute, to a greater or smaller extend, to the reproduction of stereotypes and prejudice towards minority groups. The analysis is based on the methods of critical discourse analysis, as applied by Teun A.Van Dijk (1991). The particular study was undertaken, in order to examine the unquestionable power of the Press and its ability to shape attitudes, ideologies and behavior, through the use of the powerful instrument of language.

description: Η παρούσα διπλωματική εργασία προσεγγίζει την περίοδο της δικτατορίας (1967-74) στη χώρα μας αξιοποιώντας το σχολικό αρχείο. Ειδικότερα επιχειρεί να αναδείξει τους τρόπους που επέδρασε και διείσδυσε το δικτατορικό καθεστώς στη λειτουργία του σχολείου ,το ρόλο που απαίτησε από το δάσκαλο και τη δασκάλα, τον τρόπο με τον οποίο προσπάθησε να διαμορφώσει και να πειθαρχήσει τη συμπεριφορά των μαθητών και μαθητριών.Η έρευνα μας στο σχολικό αρχείο κατέδειξε, ότι το καθεστώς προσπάθησε με κάθε τρόπο και μέσο να αποδυναμώσει το σχολείο, ως φορέα παραγωγής της γνώσης και να το μετατρέψει σε προπαγανδιστική μηχανή προσέγγισης των οικογενειών και της ευρύτερης κοινωνίας των μαθητών/τριών.Με τη χρήση αποστεωμένων σχολικών εγχειριδίων, τις απαγορεύσεις εξωσχολικών αναγνωσμάτων και ακουσμάτων , με τον έλεγχο της εμφάνισης, της συμπεριφοράς, προσπάθησε να φτιάξει άβουλα και «φρόνιμα» στρατιωτάκια. Ο δάσκαλος και η δασκάλα ως βασικοί φορείς πολιτικών γνώσεων και προτύπων συμπεριφοράς αποτέλεσαν ομάδα-στόχο για το καθεστώς. Η εργασία συνοδεύεται από μία ενδεικτική διδακτική πρόταση.
description: The present thesis (assignment) approaches the period of the dictatorship (1967-74) in our country by exploiting school files. More specifically, it tries to make known the ways the dictatorial regime affected and penetrated in the function of schools as well as the role it demanded from the teachers, the ways it tried to form (shape) and discipline the attitude of the students. Our research on school files showed that the regime tried in every way and in every means to weaken school as a vehicle to knowledge and at the same time it tried to transform it into a propagandistic mean of approaching the students’ families and society itself in a broaden term.With the use of emaciative handbooks, the prohibition of out-of- school readings, control on appearance and attitude, they tried to create weak-willed and ‘well-behaved’ pawns.Teachers as basic potential carriers of political knowledge and role models at the same time, constituted a target group for the regime.This project is accompanied by an indicative teaching suggestion.

Severe violence in Eastern Jutland 2003-2014: a pilot study
Creators: name: Kaas-Hansen, Benjamin Skov

Publisher: name: F1000Research
Year: 2015

description: Introduction — It is estimated that 1,500,000 Europeans receive treatment every year due to violence-related injuries, and in a recent report the World Health Organization calls for data-driven national violence prevention plans. Thus, we set out to study some aspects of the nature of severe violence in the Danish region of Eastern Jutland (Østjylland) over a twelve-year period (2003-2014).

Discussion — Victims in this study were older, the severity of their injuries greater, and the topographic lesion distribution different than what is seen in other studies. One explanation may be that most studies include victims of violence altogether whilst this study focused on victims of severe violence only. More and larger-scale research is warranted to allow for comprehensive data collection, further study the nature of violence, and elucidate injury patterns, to develop and strengthen the evidence base of (clinical) forensic medicine.

description: For the case where the gauge theory superpotential has a quartic term as well as the mass term for quarks, the nonsupersymmetric meta-stable brane configuration was found recently. By adding the orientifold 6-planes and the extra fundamental flavors to this brane configuration, we describe the meta-stable nonsupersymmetric vacua of the gauge theory with antisymmetric flavor as well as fundamental flavors in type IIA string theory.

description: The number field sieve is asymptotically the most efficient algorithm known for factoring large integers. It consists of several stages, the first one being polynomial selection. The running time of subsequent steps depends on the quality of the chosen polynomials. In the thesis, we discuss the current state of the art in polynomial selection. Polynomial selection can be divided into three stages: polynomial generation, size optimization and root optimization. We give some analysis of polynomial generation algorithms. We then describe some improvements for polynomial size optimization and root optimization. The size optimization is based on determining a translation and then locally optimizing the polynomial. The root optimization is based on Hensel's lifting lemma and a root sieve on congruences classes modulo small prime powers. The improvements described here have been implemented and used to obtain some good polynomials in practice. We also discuss some recent progress on polynomial selection using lattice reduction.

description: The development of direct probes of entanglement is integral to the rapidly expanding field of complex quantum materials. Here we test the robustness of entangled neutrons as a quantum probe by measuring the Clauser-Horne-Shimony-Holt contextuality witness while varying the beam properties. Specifically, we prove that the entanglement of the spin and path subsystems of individual neutrons prepared in two different experiments using two different apparatuses persists even after varying the entanglement length, coherence length, and neutron energy difference of the paths. The two independent apparatuses acting as entangler-disentangler pairs are static-field magnetic Wollaston prisms and resonance-field radio frequency flippers. Our results show that the spatial and energy properties of the neutron beam may be significantly altered without reducing the contextuality witness value below the Tsirelson bound, meaning that maximum entanglement is preserved. We also show that two paths may be considered distinguishable even when separated by less than the neutron coherence length. This work is the key step in the realization of the new modular, robust technique of entangled neutron scattering.

description: We present a stable and deterministic quantum key distribution (QKD) system based on differential phase shift. With three cascaded Mach-Zehnder interferometers with different arm-length differences for creating key, its key creation efficiency can be improved to be 7/8, more than other systems. Any birefringence effects and polarization-dependent losses in the long-distance fiber are automatically compensated with a Faraday mirror. Added an eavesdropping check, this system is more secure than some other phase-coding-based QKD systems. Moreover, the classical information exchanged is reduces largely and the modulation of phase shifts is simplified. All these features make this QKD system more convenient than others in a practical application.
