description: Emerging new concepts, such as magnetic charge dynamics in two-dimensional magnetic material, can provide novel mechanism for spin based electrical transport at macroscopic length. In artificial spin ice of single domain elements, magnetic charge's relaxation can create an efficient electrical pathway for conduction by generating fluctuations in local magnetic field that couple with conduction electrons spins. In a first demonstration, we show that the electrical conductivity is propelled by more than an order of magnitude at room temperature due to magnetic charge defects sub-picosecond relaxation in artificial magnetic honeycomb lattice. The direct evidence to the proposed electrical conduction mechanism in two-dimensional frustrated magnet points to the untapped potential for spintronic applications in this system.
The targum (1950:Feb. 3 - 1950:Feb. 28)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1950

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: Modern data-intensive applications demand high computation capabilities with strict power constraints. Unfortunately, such applications suffer from a significant waste of both execution cycles and energy in current computing systems due to the costly data movement between the computation units and the memory units. Genome analysis and weather prediction are two examples of such applications. Recent FPGAs couple a reconfigurable fabric with high-bandwidth memory (HBM) to enable more efficient data movement and improve overall performance and energy efficiency. This trend is an example of a paradigm shift to near-memory computing. We leverage such an FPGA with high-bandwidth memory (HBM) for improving the pre-alignment filtering step of genome analysis and representative kernels from a weather prediction model. Our evaluation demonstrates large speedups and energy savings over a high-end IBM POWER9 system and a conventional FPGA board with DDR4 memory. We conclude that FPGA-based near-memory computing has the potential to alleviate the data movement bottleneck for modern data-intensive applications.

description: In this work we present a revised measurement of the phase-averaged optical polarisation of the Vela pulsar (PSR B0833-45), for which only one value has been published so far (Wagner & Seifert 2000). Our measurement has been obtained through an accurate reanalysis of archival polarisation observations obtained with the FORS instrument at the VLT. We have measured a phase-averaged linear polarisation degree P=9.4% +/- 4% and a position angle 146 +/- 11 deg, very close to the ones of the axis of symmetry of the X-ray arcs and jets detected by Chandra and of the pulsar proper motion.We have compared the measured phase-averaged optical polarisation with the expectations of different pulsars' magnetosphere models. We have found that all models consistently predict too large values of the phase-averaged linear polarization with respect to the observed one. This is probably a consequence of present models' limitations which neglect the contributions of various depolarisation effects. Interestingly, for the outer gap model we have found that, assuming synchrotron radiation for the optical emission, the observed polarisation position angle also implies an alignment between the pulsar rotational axis and the axis of symmetry of the X-ray arcs and jets.

description: We investigate the Barkhausen noise in ferromagnetic thin films with zigzag domain walls. We use a cellular automaton model that describes the motion of a zigzag domain wall in an impure ferromagnetic quasi-two dimensional sample with in-plane uniaxial magnetization at zero temperature, driven by an external magnetic field. The main ingredients of this model are the dipolar spin-spin interactions and the anisotropy energy. A power law behavior with a cutoff is found for the probability distributions of size, duration and correlation length of the Barkhausen avalanches, and the critical exponents are in agreement with the available experiments. The link between the size and the duration of the avalanches is analyzed too, and a power law behavior is found for the average size of an avalanche as a function of its duration.

description: Introduction: This project is about the expenditure behavior of the 10 of the G20 countries. The G20 (or Group of Twenty) is an international forum for the governments and central bank governors from 19 countries and the European Union (EU). G20 was been founded in 1999 with the aim to discuss policy pertaining to the promotion of international financial stability, it has expanded its agenda since 2008 and heads of government or heads of state, as well as finance ministers and foreign ministers, have periodically conferred at summits ever since. It seeks to address issues that go beyond the responsibilities of any one organization. (Reference: Wikipedia) Data in this project: The 10 countries: United States, China, Japan, Germany, India, United Kingdom, France, Brazil, Italy, Canada. The 6 years: 2011, 2012, 2013, 2014, 2015 and 2016. In this report, I focus on the behavior of expenditures on Education, Healthcare and Military. Conclusion: 1. The expenditure of Healthcare takes the largest part of all the three items, which is up to 65.5%. 2. The expenditure of Military is always the least. 3. All the countries increase the percentage of the GDP on Healthcare. 4. All three expenditures have a high correlation with GDP, and the correlation between education and GDP is the highest.

Oak Street Bridge half bent test on as built and retrofitted specimens
Creators: name: Arambawela, Udhaya S.
Publisher: name: University of British Columbia
Year: 2009

description: As part of a research program on the seismic behaviour and retrofit of existing bridges, this investigation was designed to focus on column-cap beam joint regions. During the initial planning stages, a related investigation was sponsored by the Ministry of Transportation and Highways of BC to perform slow cyclic loading on large scale models of the Oak St. Bridge two-column bents. Therefore it was decided that this investigation would focus on the column-cap beam joints of the Oak St. Bridge, so that the results would have applicability to the actual bridge, and at the same time comparisons would be available between the joint tests of this investigation, and the full bent tests of the Ministry investigation. The joint tests described in this investigation comprise tests of half the two column bent, or “half bent test”. This investigation consists of the design of a test frame suitable for the half bent tests and other in plane load tests on structural assemblies such as concrete joints and their connecting members, a slow cyclic test on a 0.45 scale model of half of one of the Oak St. Bridge bents as originally constructed, and a slow cyclic test on a similar model retrofitted by post-tensioning. The latter duplicates one of the retrofit schemes also tested in the Ministry sponsored program on a 0.45 scale model of the full bent. The test frame proved suitable for the test program and for similar future testing. With a variety of options available for application of in-plane loading and restraints, it is capable of testing large scale specimens of realistic sizes for bridges and buildings. In the tests described in this thesis, it demonstrated the potential ability to duplicate the essential behaviour of the more expensive full bent tests.

description: Until recently, the physically relevant singularities occurring in FRW cosmologies had traditionally been thought to be limited to the "big bang", and possibly a "big crunch". However, over the last few years, the zoo of cosmological singularities considered in the literature has become considerably more extensive, with "big rips" and "sudden singularities" added to the mix, as well as renewed interest in non-singular cosmological events such as "bounces" and "turnarounds". In this talk, we present an extensive catalogue of such cosmological milestones, both at the kinematical and dynamical level. First, using generalized power series, purely kinematical definitions of these cosmological events are provided in terms of the behaviour of the scale factor a(t). The notion of a "scale-factor singularity" is defined, and its relation to curvature singularities (polynomial and differential) is explored. Second, dynamical information is extracted by using the Friedmann equations (without assuming even the existence of any equation of state) to place constraints on whether or not the classical energy conditions are satisfied at the cosmological milestones. Since the classification is extremely general, and modulo certain technical assumptions complete, the corresponding results are to a high degree model-independent.

Σκοπός της παρούσας μελέτης είναι η διερεύνηση της ικανότητας συναγωγής συμπερασμών παιδιών της Στ’ τάξης του δημοτικού σχολείου σε αφηγηματικά κείμενα. Εξετάζονται τα επίπεδα της συγκεκριμένης ικανότητας καθώς και η συσχέτιση της με την εργαζόμενη μνήμη και την αναγνωστική ευχέρεια. Στην έρευνα συμμετείχαν 83 μαθητές που φοιτούσαν στη Στ΄ τάξη. Για την μέτρηση των μεταβλητών χρησιμοποιήθηκαν αυθεντικά έργα κατανόησης, τεστ ανάκλησης ψηφίων και ένα έργο αναγνώρισης μεμονωμένων λέξεων. Τα αποτελέσματα έδειξαν πως οι μαθητές εμφανίζουν μεγάλη αδυναμία στη συναγωγή συμπερασμών κάθε είδους καθώς και ότι η αργή ανάγνωση δυσχεραίνει τη διαδικασία συναγωγής τους.

description: Ιnference making ability consists one of the most important skills in reading comprehension, given that bridges text’s gaps and connects local information and information from the reader’s general cognitive structure. This paper aims to investigate the ability of inference making on narrative texts. A sample of 83 students from the sixth grade of primary school participated in the study. In order to assess variables authentic texts, digit span and word recognition tests were used. Results showed that students lag inference making of every sort. Slow word recognition seems to subvert the whole procedure. Findings are discussed in the basis of equivalent theories and findings about the issue.

description: It has been recently shown that nonparametric estimators of the additive regression function could be obtained in the presence of right censoring by coupling the marginal integration method with initial kernel-type Inverse Probability of Censoring Weighted estimators of the multivariate regression function \citeDebbarhViallon3. In this paper, we get the exact rate of strong uniform consistency for such estimators. Our uniform limit laws especially lead to the construction of asymptotic simultaneous 100% confidence bands for the true regression function.

description: Investigation of near field of QED requires the refuse from an averaging of the Lorentz condition that smooths out some field peculiarities. Instead of it Schwinger decomposition of the 4-potential with the Bogoliubov method of interaction switching in time and in space regions is considered. At such approach near field is describable by the part of covariant Green function of QED, the fast-damping Schwinger function formed by longitudinal and scalar components of Aμ none restricted by light cone. This description reveals possibility of superluminal phenomena within the near field zone as a "nonlocality in the small". Some specification of Bogoliubov method allows, as examples, descriptions of near fields of point-like charge and at FTIR phenomena. Precisely such possibilities of nonlocal interactions are revealed in the common QED expressions for the Van-der-Waals and Casimir interactions and in the Förster law. Key words: Lorentz condition, near field, propagators, superluminal, FTIR. PACS: 03.30.+p, 12.20.-m, 13.40.-f, 68.37.Uv.

description: We derive a simple algebraic criterion to select the optimal detector network for a coherent wide parameter-space (all-sky) search for continuous gravitational waves. Optimality in this context is defined as providing the highest (average) sensitivity per computing cost. This criterion is a direct consequence of the properties of the multi-detector F-statistic metric, which has been derived recently. Interestingly, the choice of the optimal network only depends on the noise-levels and duty-cycles of the respective detectors, and not on the available computing power.

Hydraulic gradient similitude method for geotechnical modelling of pile group subjected to static lateral load
Creators: name: Panwalkar, Anant
Publisher: name: University of British Columbia
Year: 2009

description: The thesis considers the problem of vertical pile group response to lateral static loads. There are various solutions available for single pile response to lateral loads. These solutions have been verified against a large database obtained from field experiments and model experiments. For pile groups very few theories have been proposed and due to the comparatively smaller database available it is not possible to develop and test a sound theory for predicting the pile group response to lateral loads. This thesis is aimed at obtaining a database for response of pile groups comprising of two piles subjected to lateral static loads. Tests were carried out in the Hydraulic Gradient Similitude Device in order to bring the stress state in the soil to the field stress level. For testing purposes three cases were considered, single pile, single pile adjacent to a loaded pile, and a pile group of two piles. The single pile test results showed that the test results were repeatable and reliable. The tests on a single pile adjacent to a loaded pile showed that the position of the pile with respect to the loaded pile has a strong influence on the response of the pile. The unloaded pile in the direction of the loading and in front of the loaded pile is most effected. At a spacing of 2 diameters bending moment developed is up to a maximum of 20 percent of bending moment developed in single pile. This percentage decreases rapidly with increasing spacing. If the unloaded pile is located behind the loaded pile or is at 90° to the loading direction, it essentially picks up very little load from the loaded pile. The installation of two piles densities the soil in between. In case of pile groups, the load sharing among the piles is based on the pile location and the interaction effect is not reciprocal. The lead pile, i.e. the pile in the direction of load, shares maximum load with trail pile sharing smaller load.

description: The worldline formalism provides an alternative to Feynman diagrams in the construction of amplitudes and effective actions that shares some of the superior properties of the organization of amplitudes in string theory. In particular, it allows one to write down integral representations combining the contributions of large classes of Feynman diagrams of different topologies. However, calculating these integrals analytically without splitting them into sectors corresponding to individual diagrams poses a formidable mathematical challenge. We summarize the history and state of the art of this problem, including some natural connections to the theory of Bernoulli numbers and polynomials and multiple zeta values.

description: We study the admission control problem in general networks. Communication requests arrive over time, and the online algorithm accepts or rejects each request while maintaining the capacity limitations of the network. The admission control problem has been usually analyzed as a benefit problem, where the goal is to devise an online algorithm that accepts the maximum number of requests possible. The problem with this objective function is that even algorithms with optimal competitive ratios may reject almost all of the requests, when it would have been possible to reject only a few. This could be inappropriate for settings in which rejections are intended to be rare events. In this paper, we consider preemptive online algorithms whose goal is to minimize the number of rejected requests. Each request arrives together with the path it should be routed on. We show an $O(\log^2 (mc))$-competitive randomized algorithm for the weighted case, where $m$ is the number of edges in the graph and $c$ is the maximum edge capacity. For the unweighted case, we give an $O(\log m \log c)$-competitive randomized algorithm. This settles an open question of Blum, Kalai and Kleinberg raised in \cite{BlKaKl01}. We note that allowing preemption and handling requests with given paths are essential for avoiding trivial lower bounds.

description: Electrical mobility size spectrometers are widely used to measure ambient aerosol number size distributions. A key component of these mobility systems is the charge conditioner, or neutralizer, which is used to place a stationary charge distribution on the aerosols prior to mobility analysis. Yet, there are natural air ions in the atmosphere which are constantly conditioning the charge state of atmospheric aerosols. In this study, we demonstrate that this natural charging process can be utilized by these spectrometers to measure size distributions of atmospheric aerosols without using a conventional neutralizer. This is achieved by measuring charged particles of both polarities, in contrast to only one polarity as conventionally done. The bipolar data is used to retrieve air ion properties from which the aerosol charge fractions are calculated. We deployed this new method in urban Beijing to measure atmospheric aerosols over a period of two years and verified that size distributions can be effectively measured using natural air ions. There is good agreement in aerosol size distributions when comparing this new method to a conventional spectrometer, and good agreement in total particle number concentrations measured by a condensation particle counter. Additionally, measuring charged particles of both polarities makes the uncertainties due to aerosol charging now traceable. We show that during two years of measurement in urban Beijing, the properties of ions produced by conventional neutralizers drifted due to the aging of ion sources, while the properties of natural atmospheric ions remained stable over time, despite occasional short-period fluctuations.

description: Lithium niobate (LN), an outstanding and versatile material, has influenced our daily life for decades: from enabling high-speed optical communications that form the backbone of the Internet to realizing radio-frequency filtering used in our cell phones. This half-century-old material is currently embracing a revolution in thin-film LN integrated photonics. The success of manufacturing wafer-scale, high-quality, thin films of LN on insulator (LNOI), accompanied with breakthroughs in nanofabrication techniques, have made high-performance integrated nanophotonic components possible. With rapid development in the past few years, some of these thin-film LN devices, such as optical modulators and nonlinear wavelength converters, have already outperformed their legacy counterparts realized in bulk LN crystals. Furthermore, the nanophotonic integration enabled ultra-low-loss resonators in LN, which unlocked many novel applications such as optical frequency combs and quantum transducers. In this Review, we cover -- from basic principles to the state of the art -- the diverse aspects of integrated thin-film LN photonics, including the materials, basic passive components, and various active devices based on electro-optics, all-optical nonlinearities, and acousto-optics. We also identify challenges that this platform is currently facing and point out future opportunities. The field of integrated LNOI photonics is advancing rapidly and poised to make critical impacts on a broad range of applications in communication, signal processing, and quantum information.

description: The isolated susceptibility $χ_{\rm I}$ may be defined as a (non-thermodynamic) average over the canonical ensemble, but while it has often been discussed in the literature, it has not been clearly measured. Here, we demonstrate an unambiguous measurement of $χ_{\rm I}$ at avoided nuclear-electronic level crossings in a dilute spin ice system, containing well-separated holmium ions. We show that $χ_{\rm I}$ quantifies the superposition of quasi-classical spin states at these points, and is a direct measure of state concurrence and populations.

Color-Magnitude Diagrams of Resolved Stars in Virgo Cluster Dwarf Galaxies

description: The Advanced Camera for Surveys (ACS) on HST has been used to image two fields in the core of the Virgo cluster that contain a number of dwarf elliptical galaxies. The combined F555W and F814W images have resolved red giant stars in these galaxies, down to 1 mag below the giant branch tip. Two of the galaxies were targeted because of their extremely low central surface brightnesses (Bo > 27.0), thus the successful resolution into stars confirms the existence of such tenuous galaxies. Red giant stars were also found that are not ostensibly associated with any galaxy. Color-magnitude diagrams in V and I have been derived and used to derive distances and metallicities via the magnitude and mean color of the red giant branch tip. The mean abundances of stars in the dwarfs range from -1.2 [Fe/H] < -2.4, and fall along the relation between galaxy luminosity and metallicity found for Local Group and M81 group dwarf ellipticals. The mean distance modulus of the six Virgo galaxies is 31.0 +/- 0.05, or 16.1 +/- 0.4 Mpc, whereas that for the intracluster stars in those fields is 31.2 +/- 0.09 (17.4 +/- 0.7 Mpc).

Canonical Cortical Circuits and the Duality of Bayesian Inference and Optimal Control

description: The duality of sensory inference and motor control has been known since the 1960s and has recently been recognized as the commonality in computations required for the posterior distributions in Bayesian inference and the value functions in optimal control. Meanwhile, an intriguing question about the brain is why the entire neocortex shares a canonical six-layer architecture while its posterior and anterior halves are engaged in sensory processing and motor control, respectively. Here we consider the hypothesis that the sensory and motor cortical circuits implement the dual computations for Bayesian inference and optimal control, or perceptual and value-based decision making, respectively. We first review the classic duality of inference and control in linear quadratic systems and then review the correspondence between dynamic Bayesian inference and optimal control. Based on the architecture of the canonical cortical circuit, we explore how different cortical neurons may represent variables and implement computations.

description: Recently, atomic ensemble and single photons were successfully entangled by using collective enhancement [D. N. Matsukevich, \textit{et al.}, Phys. Rev. Lett. \textbf{95}, 040405(2005).], where atomic internal states and photonic polarization states were correlated in nonlocal manner. Here we experimentally clarified that in an ensemble of atoms and a photon system, there also exists an entanglement concerned with spatial degrees of freedom. Generation of higher-dimensional entanglement between remote atomic ensemble and an application to condensed matter physics are also discussed.

description: Σκοπός της παρούσας μελέτης είναι να διερευνηθούν ο Τρισάγιος ύμνος και το τροπάριο «ο Μονογενής» στις λειτουργίες των Βυζαντινών εκκλησιών και των αντιχαλκηδόνιων παραδόσεων, τον χρόνο εισαγωγής τους στην Λειτουργία, την θεολογική τους προσέγγιση και τις απόψεις των μελετητών ως προς την πατρότητα των ύμνων αυτών. Οι λειτουργικοί ύμνοι αποτέλεσαν έκφραση των δογμάτων των χριστιανικών παραδόσεων. Ο Τρισάγιος ύμνος αποτελεί Τριαδολογική δογματική έκφραση για την Ορθόδοξη Καθολική εκκλησία και το Τροπάριο ο Μονογενής Υιός χριστολογική. Ο Θεολογικός τρόπος κατανόησης των ύμνων διαφοροποιήθηκε σύμφωνα με τις εξελίξεις των αποφάσεων των Οικουμενικών συνόδων. Οι αντιχαλκηδόνιες παραδόσεις ερμήνευσαν τον Τρισάγιο ύμνο χριστολογικά και αυτό αποτυπώθηκε με την προσθήκη «ο σταυρωθείς δι’ ημάς» στον Τρισάγιο ύμνο. Ο Μονογενής Υιός εισήχθηκε από τον αυτοκράτορα Ιουστινιανό, ώστε να γεφυρωθεί το χάσμα που προκλήθηκε από τις αντιχαλκηδόνιες έριδες. Στη μελέτη αυτή παρουσιάσαμε την Θέση των ύμνων στην Λειτουργική αναφορά και την Θεολογική και δογματική προσέγγισή τους. Η πατρότητα των ύμνων μας απασχόλησε σε ιδιαίτερο κεφάλαιο, επειδή προφανώς, και αυτή αποτέλεσε σημείο διαφοροποίησης
description: The aim of the present research is to investigate the hymn of Trisagion and the troparion "The only Begotten Son" (o Monogenis Yios) in the liturgical tradition of the Byzantium churches and non-Chalcedon and Nestorian tradition, the time of introducing these hymns in the liturgy, their theological approach and the views about the authority of these hymns. The liturgical hymns were an expression of the doctrines of Christian traditions. The hymn of Trisagion expresses in Triadological way the doctrine of the Orthodox Catholic Church and the troparion of “The only Begotten Son” the Christoogical way. The theological way of understanding of these hymns had peculiarity, depending on the decisions of the Ecumenical Councils. The non- Chalcedon traditions interpretate the Trisagion hymn in Christological way and expressed that with the additional words “who was crucified for us”. The troparion “only begotten Son” was introduced by Justinian the Emperor to bridge the gap that happened in the non-Chalchedonian dispute. In this research we introduced the place of the hymns in the Liturgical anaphora and the theological and doctrine approach of them. The authority of the Hymns is discussed in a separated chapter, because it is a point of differentiations
