description: We use point contact Andreev reflection spin spectroscopy to measure the transport spin polarization of MnAs epitaxial films grown on (001) GaAs. By analyzing both the temperature dependence of the contact resistance and the phonon spectra of lead acquired simultaneously with the spin polarization measurements, we demonstrate that all the point contacts are in the ballistic limit. A ballistic transport spin polarization of approximately 49% and 44% is obtained for the type A and type B orientations of MnAs, respectively. These measurements are consistent with our density functional calculations, and with recent observations of a large tunnel magnetoresistance in MnAs/AlAs/(Ga,Mn)As tunnel junctions.

description: We numerically compute the density of states (DOS) of interacting disordered zigzag graphene nanoribbon (ZGNR) having midgap states showing $e/2$ fractional edge charges. The computed Hartree-Fock DOS is linear at the critical disorder strength where the gap vanishes. This implies an $I\mbox{-}V$ curve of $I\propto V^2$. Thus, $I\mbox{-}V$ curve measurement may yield evidence of fractional charges in interacting disordered ZGNR. We show that even a weak disorder potential acts as a singular perturbation on zigzag edge electronic states, producing drastic changes in the energy spectrum. Spin-charge separation and fractional charges play a key role in the reconstruction of edge antiferromagnetism. Our results show that an interacting disordered ZGNR is a topologically ordered Mott-Anderson insulator.

description: This paper is devoted to the study of the knot Floer homology groups HFK(S^3,K_{2,n}), where K_{2,n} denotes the (2,n) cable of an arbitrary knot, K. It is shown that for sufficiently large |n|, the Floer homology of the cabled knot depends only on the filtered chain homotopy type of CFK(K). A precise formula for this relationship is presented. In fact, the homology groups in the top 2 filtration dimensions for the cabled knot are isomorphic to the original knot's Floer homology group in the top filtration dimension. The results are extended to (p,pn+-1) cables. As an example we compute HFK((T_{2,2m+1})_{2,2n+1}) for all sufficiently large |n|, where T_{2,2m+1} denotes the (2,2m+1)-torus knot.

description: Σκοπός της διατριβής ήταν η μελέτη της συμμετοχής του λαϊκού στοιχείου στην εκλογή Επισκόπων, Αρχιεπισκόπου και Μητροπολιτών, στην Εκκλησία της Κύπρου κατά την περίοδο 1850 μέχρι 1970. Ο περιορισμένος αριθμός των μελών της Ιεράς Συνόδου της Εκκλησίας της Κύπρου, δηλαδή ένας Αρχιεπίσκοπος και τρεις Μητροπολίτες, δημιουργούσε προβλήματα και επιζητήθηκε η συμμετοχή λαϊκών για τη συγκρότηση μιας εκλογικής συνέλευσης που θα έδινε την εντύπωση κανονικής εκλογής. Η αρχική λύση που δόθηκε ήταν η συμμετοχή κάποιων λαϊκών, για την οποία από κάποια χρονική περίοδο γνωρίζουμε ότι ήταν εκλογή της οικείας επισκοπικής περιφέρειας. Το σύστημα αυτό τροποποιείται λίγο πριν το τέλος του 19ου αιώνα, όταν ο Αρχιεπίσκοπος Σωφρόνιος Γ΄ κατά την επίσκεψή του στην Κωνσταντινούπολη ενημερώθηκε για τον τρόπο εκλογής Οικουμενικού Πατριάρχη με τη συμμετοχή λαϊκών. Στο σύστημα που εφαρμόστηκε στην Κύπρο γινόταν εκλογή ειδικών αντιπροσώπων και στη συνέχεια μικρότερου αριθμού γενικών αντιπροσώπων, από τους οποίους το ένα τρίτο έπρεπε να είναι ιερείς ή και διάκονοι. Λόγω των πολλών προβλημάτων που προκαλούσε το σύστημα, αυτό αντικαταστάθηκε το 2010 από άλλο σύστημα πάλι με συμμετοχή του λαού αλλά λιγότερο προβληματικού
description: The purpose of the present thesis was to study the participation of the popular element in the election of Bishops, Archbishops and Metropolitans in the Church of Cyprus during the period 1850 to 1970. The limited number of members of the Holy Synod of the Church of Cyprus, ie one Archbishop and three Metropolitans, created problems and the participation of the people was sought for the formation of an electoral assembly that would give the impression of a normal election. The initial solution that was given was the participation of some laity, which for some time we know was the election of the relevant episcopal region. This system was modified shortly before the end of the 19th century, when Archbishop Sophronios III during his visit to Constantinople was informed about the way of electing an Ecumenical Patriarch with the participation of the laity. In the system implemented in Cyprus, special representatives were elected and then a smaller number of general representatives, one third of whom had to be priests or even deacons. Due to the many problems caused by the system, it was replaced in 2010 by another system again with the participation of the people but less problematic

description: This research highlight presents an overview of agricultural land ownership, distribution, use, and tenure for rural households in Southern Shan State, and how this has changed compared to the previous generation. All findings are from the Shan Agriculture and Rural Economy Survey (SHARES) which was conducted during June-july 2018 with 1562 rural households in nine townships of Southern Shan State: Taunggyi, Hopong, Lawksawk, Pindaya, Mongnai, Langkho, Hsihseng, Pinlaung and Pekon. In this highlight, we use the term ‘farm households’ for households who are cultivating crops, whether or not they own land. We refer to households who do not grow crops as ‘non-farm households’. ‘Landed households’ refers to households who own agricultural land, and ‘landless households’ to households who do not own agricultural land. Furthermore, we also classify households by landholding terciles. Terciles are obtained by ranking all landed households in ascending order of landholding size and dividing into three groups with an equal number of households in each group. Tercile 1 consists of the third of households with the smallest farms, while tercile 3 consists of the third of households with the largest farms.

description: This report outlines recent (2007-2017) changes in agricultural practices for the main field crops grown in Myanmar’s Dry Zone, based on information gathered from the Rural Economy and Agriculture Dry Zone (READZ) survey. Myanmar’s Dry Zone is a vast area in the North-Central part of the country, spanning three different regions (Sagaing, Mandalay and Magway) and including the country’s second-largest city of Mandalay. The survey was carried out in April of 2017 in the townships of Budalin, Myittha, Magway and Pwintbyu. One objective of the survey was to assess trends in production patterns and practices for four of the major field crops grown in the area: rice, groundnut, sesame, and green gram. This was done by collecting recall data for three time periods: the year of the survey (2017, corresponding to the 2016-2017 growing season), five years prior (2012), and ten years prior (2007). Each farmer was asked only about their most important crop, so the results pertain not to all farmers growing a given crop, but rather to those specializing in each crop. This analysis allowed us to compare how production of the four major crops has evolved over the past ten years in terms of seasonality, technology and input use, and yields, and to identify evidence of any technological change and modernization occurring.
Compton recoil effects in staging of laser wakefield accelerators

description: Laser plasma accelerators capable of generating >10 GeV electron beams may require plasma mirrors to remove undepleted laser energy at the end of each accelerator stage. Near the plasma mirror surface, the electron bunch can interact with the reflected light, resulting in inverse Compton scattering. For realistic conditions, we show that a significant fraction of electrons emit one or more photons, increasing the energy spread of the electron bunch. We provide an analytical expression for calculating this effect, and use it to estimate the minimum drift space required before the plasma mirror to meet given energy spread specifications. Mitigation strategies, necessary to achieve sub-percent energy spread in multi-GeV laser wakefield electron sources, are proposed and explored.

description: Deep surveys indicate a bubbly structure of cosmological large scale which should be the result of evolution of primordial density perturbations. Several models have been proposed to explain origin and dynamics of such features but, till now, no exhaustive and fully consistent theory has been found. We discuss a model where cosmological black holes, deriving from primordial perturbations, are the seeds for large-scale-structure voids. We give details of dynamics and accretion of the system voids-cosmological black holes from the epochs $(z\simeq10^{3})$ till now finding that void of $40h^{-1}Mpc$ of diameter and under-density of -0.9 will fits the observations without conflicting with the homogeneity and isotropy of cosmic microwave background radiation.

description: The aim of this project is to support Nurse Practitioners in navigating the complex world of non-pharmacological interventions for irritable bowel syndrome (IBS) by creating a one-page clinical information sheet for use in practice. IBS is a chronic functional gastrointestinal disorder commonly seen in primary care and the pathophysiology of IBS is largely unknown, leading to a wide variety of interventions. Non-pharmacological interventions are suggested first-line therapies for IBS. A literature review was conducted to assess the state of the evidence for fiber supplementation, traditional IBS dietary advice, the low-FODMAP diet, exercise and psychological therapies. All of these interventions have some part to play in an IBS management plan, with traditional IBS dietary advice and the low-FODMAP diet having the strongest evidence for efficacy in treating IBS.

Während fünf Wochen wurde sechs Kindern dialogisch vorgelesen. Mit einem Prä-Post-Kontrollgruppendesign wurden anhand des Salzburger Lese-Screenings die Veränderungen des Lesequotienten quantitativ ausgewertet. Mittels Fragebogen wurde überprüft, ob ein Zusammenhang zwischen den basalen Lesefertigkeiten und der Lesemotivation besteht und ob die Vorleseerfahrung einen Einfluss darauf hat. Die Hälfte der Kinder der Experimentalgruppe hatte einen grösseren Zuwachs im Lesequotienten als die Kinder der Kontrollgruppe. Es zeigte sich eine Tendenz, dass eine höhere Lesemotivation mit besseren Lesefertigkeiten einhergeht. Aufgrund der kleinen Stichprobe sind die Ergebnisse jedoch nicht zu verallgemeinern.

description: It is now well established that the unique properties of relaxor ferroelectrics are due to the presence of polar nanoregions (PNR's). We present recent results from Neutron and Raman scattering of single crystals of PZN, PZN-xPT, and PMN. Both sets of measurements provide information on the condensation of the PNR's and on their slow dynamics, directly through the central peak and, indirectly, through their coupling to transverse phonons. A comparative analysis of these results allows identification of three stages in the evolution of the PNR's with decreasing temperature: a purely dynamic stage, a quasi-static stage with reorientational motion and a frozen stage. A model is proposed, based on a prior study of KTN, which explains the special behavior of the transverse phonons (TO and TA) in terms of their mutual coupling through the rotations of the PNR's.

By variating an appropriate action for each case, we obtain generalized forms of paths and generalized field equations for a Sasaki type metric. We show that Stokes theorem is modified with respect to general relativity due to local anisotropy and the presence of a nonlinear connection which induces an adapted basis in our space.

MEASURING AGGREGATE SUPPLY RESPONSE UNDER INSTABILITY

Subjects: Risk and Uncertainty

description: In spite of the strong interests that agricultural economists have had in measuring aggregate supply response in the past there are only a few studies that explicitly introduced the risk element into the models (e.g. Behrman, Just, Traill). Behrman quantified both yield and price variabilities by using three-year moving average standard deviations about a simple moving average of yield and price. Just formulated a risk response model by assuming that decision makers would form their risk expectations by geometrically weighting past observations of risk similar to the way in which price and yield expectations are formed. The risk variable was taken to be the square of the difference between the actual explanatory variable (such as gross return) and the expected values. Each lag variable was then divided into observable and unobservable parts similar to the approach suggested by Klein. Assuming the disturbance term follows a normal distribution, an iterative procedure was undertaken to derive the maximum likelihood estimates of the regression coefficients, given values of the lag parameters and the internally generated risk observations. Results obtained from Just's multivariate adapative expectations model often indicated risk to be significant in acreage response.

description: This report summarizes the final results from the OPAL collaboration on searches for neutral Higgs bosons predicted by the Minimal Supersymmetric Standard Model (MSSM). CP-conserving and for the first time at LEP CP-violating scenarios are studied. New scenarios are also included, which aim to set the stage for Higgs searches at future colliders. The results are based on the data collected with the OPAL detector at e+e- centre-of-mass energies up to 209 GeV. The data are consistent with the prediction of the Standard Model with no Higgs boson produced. Model-independent limits are derived for the cross-section of a number of events topologies motivated by prediction of the MSSM. Limits on Higgs boson masses and other MSSM parameters are obtained for a number of representative MSSM benchmark scenarios. For example, in the CP-conserving scenario mh-max where the MSSM parameters are adjusted to predict the largest range of values for mh at each tan beta, and for a top quark mass of 174.3 GeV, the domain 0.784.5 GeV and ma>85.0 GeV are obtained. For the CP-violating benchmark scenario CPX which, by construction, enhances the CP-violating effects in the Higgs sector, the domain tan beta<2.8 is excluded but no universal limit can be set on the Higgs boson masses.

description: We aimed to explore the utility of the recently developed open-source mobile health platform RADAR-base as a toolbox to rapidly test the effect and response to NPIs aimed at limiting the spread of COVID-19. We analysed data extracted from smartphone and wearable devices and managed by the RADAR-base from 1062 participants recruited in Italy, Spain, Denmark, the UK, and the Netherlands. We derived nine features on a daily basis including time spent at home, maximum distance travelled from home, maximum number of Bluetooth-enabled nearby devices (as a proxy for physical distancing), step count, average heart rate, sleep duration, bedtime, phone unlock duration, and social app use duration. We performed Kruskal-Wallis tests followed by post-hoc Dunns tests to assess differences in these features among baseline, pre-, and during-lockdown periods. We also studied behavioural differences by age, gender, body mass index (BMI), and educational background. We were able to quantify expected changes in time spent at home, distance travelled, and the number of nearby Bluetooth-enabled devices between pre- and during-lockdown periods. We saw reduced sociality as measured through mobility features, and increased virtual sociality through phone usage. People were more active on their phones, spending more time using social media apps, particularly around major news events. Furthermore, participants had lower heart rate, went to bed later, and slept more. We also found that young people had longer homestay than older people during lockdown and fewer daily steps. Although there was no significant difference between the high and low BMI groups in time spent at home, the low BMI group walked more. RADAR-base can be used to rapidly quantify and provide a holistic view of behavioural changes in response to public health interventions as a result of infectious outbreaks such as COVID-19.

description: Το περιοδικό Σημερινά Γράμματα υπήρξε βραχύβιο λογοτεχνικό και καλλιτεχνικό έντυπο που στόχευε στην αναθεώρηση των λογοτεχνικών και πνευματικών αξιών. Η εργασία παρακολουθεί την εξέλιξή του και επιχειρεί να αναδείξει τη συμβολή του στην ελληνική πνευματική ζωή της περιόδου, παρουσιάζοντας και μελετώντας τα θέματα, τους συνεργάτες και τη συνομιλία του με άλλα έντυπα της εποχής. Ο Αλκιβιάδης Γιαννόπουλος, εκδότης και διευθυντής των Σημερινών Γραμμάτων, διατηρούσε αλληλογραφία με τους συνεργάτες του, μέσα από την οποία προκύπτουν στοιχεία που συμπληρώνουν τη φυσιογνωμία του περιοδικού. Μέσω της ανάλυσης των δημοσιευμένων θέσεων για θέματα που αφορούν την κοινωνία, την πνευματική ζωή και τη λογοτεχνία, επιχειρείται η ανασύνθεση της προσωπικότητας του Γιαννόπουλου και αναδεικνύεται ο ρόλος και ο χαρακτήρας του περιοδικού. Για την καλύτερη παρακολούθηση του περιεχομένου των Σημερινών Γραμμάτων, συγκροτούνται ευρετήρια κατά τεύχος, που συνοδεύονται από εκτενή σχολιασμό της δημοσιευμένης ύλης και ευρετήρια κατά συνεργάτη, ενώ παράλληλα αξιοποιούνται και οι επιστολές που αφορούν την έκδοση του περιοδικού. Η έρευνα αξιοποιεί το διαθέσιμο υλικό του Αλκιβιάδη Γιαννόπουλου που απόκειται στο Αρχείο Νεοελληνικής Λογοτεχνίας του Τμήματος Φιλολογίας
description: The magazine Today's Letters was a short-lived literary and art document aiming to the recension of literal and intellectual principles. This assignment monitors its progress and attempts to point out its contribution to the Greek intellectual life of that period by featuring and studying its issues, partners and interaction with other documents of that time. Alkiviades Giannopoulos, publisher and editor of the magazine, kept correspondence with his partners through which lots of details about the nature of the magazine arise. Through the analysis of his publicized views about matters which have to do with society, intellectual life and literature, not only is the reformulation of Giannopoulos' personality attempted but also the role and character of the magazine is featured. In order to monitor the magazine's content better, indexes per issue accompanied by detailed commentary of publicized material and indexes per partner will be constituted while all the letters about the publication of the magazine will be deployed. The project will make good use of all the available Giannopoulos ' archival material of Modern Greek Literature archive of Philology department as it rests, among others, with the archive of the magazine

description: We present the formulae for twist quantization of $g_2$, corresponding to the solution of classical YB equation with support in the 8-dimensional Borel subalgebra of $g_2$. The considered chain of twists consists of the four factors describing the four steps of quantization: Jordanian twist, the two twist factors extending Jordanian twist and the deformed Jordanian or in second variant additional Abelian twist. The first two steps describe as well the $sl(3)$ quantization. The coproducts are calculated for each step in explicite form, and for that purpose we present new formulas for the calculation of similarity transformations on tensor product. We introduce new basic generators in universal enveloping algebra $U(g_2)$ which provide nonlinearities in algebraic sector maximally simplifying the deformed coproducts.

description: We propose an original approach to describe the scientific progress in a quantitative way. Using innovative Machine Learning techniques we create a vector representation for the PACS codes and we use them to represent the relative movements of the various domains of Physics in a multi-dimensional space. This methodology unveils about 25 years of scientific trends, enables us to predict innovative couplings of fields, and illustrates how Nobel Prize papers and APS milestones drive the future convergence of previously unrelated fields.

Quantifying Entanglement Production of Quantum Operations

Year: 2003
Subjects: subject: Quantum Physics (quant-ph)

subject: FOS: Physical sciences

description: The problem of entanglement produced by an arbitrary operator is formulated and a related measure of entanglement production is introduced. This measure of entanglement production satisfies all properties natural for such a characteristic. A particular case is the entanglement produced by a density operator or a density matrix. The suggested measure is valid for operations over pure states as well as over mixed states, for equilibrium as well as nonequilibrium processes. Systems of arbitrary nature can be treated, described either by field operators, spin operators, or any other kind of operators, which is realized by constructing generalized density matrices. The interplay between entanglement production and phase transitions in statistical systems is analysed by the examples of Bose-Einstein condensation, superconducting transition, and magnetic transitions. The relation between the measure of entanglement production and order indices is analysed.
