description: To study noncommutativity properties of the open string with constant B-field we construct a mechanical action which reproduces classical dynamics of the string sector under consideration. It allows one to apply the Dirac quantization procedure for constrained systems in a direct and unambiguous way. The mechanical action turns out to be the first order system without taking the strong field limit $B\longrightarrow\infty$. In particular, it is true for zero mode of the string coordinate which means that the noncommutativity is intrinsic property of this mechanical system. We describe the arbitrariness in the relation existent between the mechanical and the string variables and show that noncommutativity of the string variables on the boundary can be removed. It is in correspondence with the result of Seiberg and Witten on relation among noncommutative and ordinary Yang-Mills theories. The recently developed soldering formalism helps us to establish a connection between the original open string action and the Polyakov action.

The legal status of lottery schemes in Canada : changing the rules of the game
Creators: name: Osborne, Judith Anne
Publisher: name: University of British Columbia
Year: 2010

description: The term "lottery scheme" is a generic one used in the Criminal Code of Canada to encompass both true lotteries and other games of chance. Until 1969, the Criminal Code prohibited such gambling activities, with the exception of very small scale, occasional and private lottery schemes run for charitable purposes, and lottery schemes operated at agricultural fairs. This criminal prohibition was a longstanding one which had existed in Canada since before Confederation. Twenty years ago, however, the Criminal Code was amended to permit state-operated and state-licensed lottery schemes. As a consequence of this relaxation of the criminal law, legalized gambling has, since the early 1970s, flourished and become firmly established in Canadian society. In part, this reflects a general international trend; similar developments have taken place in the United States, Australia and Europe. In Canada, however, this development occurred in the absence of widespread public debate, political rationalization or academic analysis. There is not much known about how or why it came about, its legal validity, or what its implications are. This thesis addresses these neglected issues, provides some understanding of how the legal status of lottery schemes was transformed in 1969, why it occurred and what its consequences have been. These aims are achieved through an examination of five distinct but related research dimensions: legal history, political process, legal theory, constitutional law and administrative law. This study finds that what was a fairly radical change in the rules regarding lottery schemes was achieved relatively quickly, with a minimum of fuss and very little in the way of public discussion. It was a silent transformation. This lack of debate is at least partly responsible for the incoherent response on the part of some provinces, which soon took advantage of their ability to conduct and manage lottery schemes, but did not appear to have an articulate gaming control policy. It is shown that while there were well-established, philosophically sound reasons for the removal of criminal sanctions from certain gambling games, there were also political, social and economic reasons which were equally if not more important in explaining its occurrence. These justifications even overrode the legal constraints of Canada's constitutional framework: the decriminalization of lottery schemes was achieved through a dubious interdelegation of powers between the federal and provincial legislatures. Not only is this arrangement constitutionally unsound, but it also ignored the interests of an important segment of Canada's population: its aboriginal peoples. The right to conduct and control gaming on Indian lands is the focus of a tri-partite jurisdictional struggle which will likely soon force a re-examination of the legal status lottery schemes in Canada.

description: D1 magic wavelengths have been predicted for the alkali atoms but are not yet observed to date. We experimentally confirm a D1 magic wavelength that is predicted to lie at 615.87 nm for $^{23}$Na, which we then use to trap and image individual atoms with 80.0(6)% efficiency and without having to modulate the trapping and imaging light intensities. We further demonstrate that the mean loading efficiency remains as high as 74.2(7)% for a 1D array of eight atoms. Leveraging on the absence of trap intensity modulation and lower trap depths afforded by the D1 light, we achieve an order-of-magnitude reduction on the tweezer laser power requirements and a corresponding increase in the scalability of atom arrays. The methods reported here are applicable to all the alkalis, including those that are attractive candidates for dipolar molecule assembly, Rydberg dressing, or are fermionic in nature.

description: Η διατριβή θέτει ως υπόθεση ότι οι Βίοι των Αγίων μπορούν να λειτουργούν ως μέσο θετικής ηθικής χριστιανικής κοινωνικοποίησης, δηλαδή ένταξης των παιδιών στην Εκκλησία αλλά και της ευρύτερης κοινωνικοποίησης. Για την επιστημονική προσέγγιση του θέματος χρησιμοποιείται η μέθοδος της ανάλυσης του περιεχομένου των Βίων των Αγίων με βάση τη θεωρία του καθηγητή Β. Πρόπ. Το πεδίο της έρευνας μας αποτελείται από ένα σώμα των Bίων Αγίων που εκδόθηκαν από τη Ιερά Επισκοπή Roman της Ρουμανίας. Η μελέτη περιέχει πέντε κεφάλια. Στο πρώτο κεφάλαιο εξετάζεται η κοινωνικοποίηση. Αναφέρονται οι σημαντικότερες θεωρίες της κοινωνικοποίησης, οι τύποι και οι φορείς της. Στο δεύτερο κεφάλ αιο, μέσα από μια ιστορικο-κοινωνική αναφορά, εξετάζονται τα παιδικά αφηγήματα, προφορικού, γραπτού και εικονικού λόγου, ως μέσο κοινωνικοποίησης των παιδιών. Στο τρίτο κεφάλαιο διερευνάται η ηθική διαπαιδαγώγηση των παιδιών σε σχέση με τα ηθικά πρότυπα που προσφέρουν οι Βίοι Αγίων, με βάση τη σύγχρονη παιδαγωγική προσέγγιση. Στο τέταρτο κεφάλαιο μελετάμε τα κύρια στοιχεία των Βίων των Αγίων. Στο πέμπτο κεφάλαιο συνοψίζονται τα δεδομένα της συγκριτικής ανάλυσης: εκτός από τα στοιχεία των Βίων που είναι ίδια με τα δομικά στοιχεία πάνω στα οποία έχουν κατασκευαστεί τα μαγικά παραμύθια εμφανίζονται και άλλα ιδιαίτερα στοιχεία (λειτουργίες-ενέργιες).
description: The dissertation sets the assumption that The Lives of the Saints can operate as an agent for positive Christian ethic socialization (inclusion of the children in the Church and the wider socialization). The scientific approach uses in the method of analysis of The Lives of the Saints based on the theory of Professor V. Propp. The research field comprises a body of Lives that issued by the Diocese of Roman, Romania. The study contains five chapters. The first chapter examines the socialization, the most important theories of socialization, the types and the institutions of socialization. The second chapter, through a historical-social report examines the spoken, written and virtual tales as an agent of socializing children. The third chapter investigates the moral education of children in relation to the ethical models that offer The Lives of the Saints, based on modern pedagogical approaches. The fourth chapter examines the main elements of The Lives of the Saints. Τhe fifth chapter summarizes the conclusions of the comparative analysis - The Lives of the Saints contains the same elements of the magical tales and other special features named functions – energies.
On the elastic moduli of three-dimensional assemblies of spheres: characterization and modeling of fluctuations in the particle displacement and rotation

description: The elastic moduli of four numerical random isotropic packings of Hertzian spheres are studied. The four samples are assembled with different preparation procedures, two of which aim to reproduce experimental compaction by vibration and lubrication. The mechanical properties of the samples are found to change with the preparation history, and to depend much more on coordination number than on density. Secondly, the fluctuations in the particle displacements from the average strain are analysed, and the way they affect the macroscopic behavior analyzed. It is found that only the average over equally oriented contacts of the relative displacement these fluctuations induce is relevant at the macroscopic scale. This average depends on coordination number, average geometry of the contact network and average contact stiffness. As far as the separate contributions from particle displacements and rotations are concerned, the former is found to counteract the average strain along the contact normal, while the latter do in the tangential plane. Conversely, the tangential components of the center displacements mainly arise to enforce local equilibrium, and have a small, and generally stiffening effect at the macro-scale. Finally, the fluctuations and the shear modulus that result from two approaches available in the literature are estimated numerically. These approaches are both based on the equilibrium of a small-sized representative assembly. The improvement of these estimate with respect to the average strain assumption indicates that the fluctuations relevant to the macroscopic behavior occur with short correlation length.

description: The objective of this thesis is the design and evaluation of a proposed software architecture (MAPIS3 - Mediating Adaptation Patterns and Intelligent Systems) as a solution to the problem of flexible design and implementation of collaborative learning scenarios with computer support ("CSCL scenarios"). The aim of the thesis is that the architecture is based on accepted standards in the area of technology supported learning (such as IMS-LD web services) that enhance flexibility. The architecture was evaluated: a) from the technological viewpoint of developers, and b) from the pedagogical aspect of designers-teachers and learners. Technological evaluation focuses on data exchange and technological interconnection of tools used in CSCL scenarios. The pedagogical evaluation focuses on orchestration of tools and their integration into CSCL scenarios that require flexible design and more importantly execution.

description: The SOM algorithm is very astonishing. On the one hand, it is very simple to write down and to simulate, its practical properties are clear and easy to observe. But, on the other hand, its theoretical properties still remain without proof in the general case, despite the great efforts of several authors. In this paper, we pass in review the last results and provide some conjectures for the future work.
Effect of the Spatial Dispersion on the Shape of a Light Pulse in a Quantum Well

description: Reflectance, transmittance and absorbance of a symmetric light pulse, the carrying frequency of which is close to the frequency of interband transitions in a quantum well, are calculated. Energy levels of the quantum well are assumed discrete, and two closely located excited levels are taken into account. A wide quantum well (the width of which is comparable to the length of the light wave, corresponding to the pulse carrying frequency) is considered, and the dependance of the interband matrix element of the momentum operator on the light wave vector is taken into account. Refractive indices of barriers and quantum well are assumed equal each other. The problem is solved for an arbitrary ratio of radiative and nonradiative lifetimes of electronic excitations. It is shown that the spatial dispersion essentially affects the shapes of reflected and transmitted pulses. The largest changes occur when the radiative broadening is close to the difference of frequencies of interband transitions taken into account.

description: The electroweak symmetry breaking (EWSB) mechanism is still an undecided question in particle physics. We propose to utilize the single top quark and Higgs associated production ($th$), $Zh$ production via gluon fusion at the LHC to probe the couplings between the Higgs and the gauge bosons and further to test the EWSB. We demonstrate that the $th$ and $gg\to Zh$ productions are sensitive to the relative sign of couplings ($ht\bar{t}$, $hWW$) and ($ht\bar{t}$, $hZZ$), respectively. We find that the relative sign between $hWW$ and $hZZ$ couplings could be fully determined after combining the present measurements from $gg\to h$, $t\bar{t}h$ and the $th$, $Zh$ channels, as well as $tZj$ and $Zt\bar{t}$ production at the 13 TeV LHC, and this conclusion is not sensitive to the possible new physics contribution induced by $Zt\bar{t}$ couplings in the $gg\to Zh$ production.

description: The electronic structure of Bi2Sr2-xRxCuOy(R=La, Eu) near the (pi,0) point of the first Brillouin zone was studied by means of angle-resolved photoemission spectroscopy (ARPES). The temperature T* above which the pseudogap structure in the ARPES spectrum disappears was found to have an R dependence that is opposite to that ofthe superconducting transition temperature Tc. This indicates that the pseudogap state is competing with high-Tc superconductivity, and the large Tc suppression observed with increasing the out-of-plane disorder is due to the stabilization of the pseudogap state.

description: The WIMP proposed here yields the observed abundance of dark matter, and is consistent with the current limits from direct detection, indirect detection, and collider experiments, if its mass is $\sim 72$ GeV/$c^2$. It is also consistent with analyses of the gamma rays observed by Fermi-LAT from the Galactic center (and other sources), and of the antiprotons observed by AMS-02, in which the excesses are attributed to dark matter annihilation. These successes are shared by the inert doublet model (IDM), but the phenomenology is very different: The dark matter candidate of the IDM has first-order gauge couplings to other new particles, whereas the present candidate does not. In addition to indirect detection through annihilation products, it appears that the present particle can be observed in the most sensitive direct-detection and collider experiments currently being planned.

description: A non-contact scanning-probe-microscopy method was used to probe local near-surface dielectric susceptibility and dielectric relaxation in poly-vinyl-acetate (PVAc) near the glass transition. Dielectric spectra were measured from 10-4 Hz to 102 Hz as a function of temperature. The measurements probed a 20 nm thick layer below the free-surface of a bulk film. A small (4 K) reduction in glass transition temperature and moderate narrowing of the distribution of relaxation times was found. In contrast to results for ultra-thin-films confined on or between metallic electrodes, no reduction in the dielectric strength was found, inconsistent with the immobilization of slower modes.

description: Tra i grammatici e i maestri che a partire dal XVI secolo hanno dato alle stampe riflessioni sulla lingua tedesca e raccomandazioni per il suo insegnamento, Valentin Ickelsamer si distingue per il taglio didattico fortemente innovativo. Forse non è solo una coincidenza che il suo libro Ain Teütsche Grammatica venga pubblicato a Marburg nel 1535, ovvero nello stesso anno in cui a Wittenberg l’editore Lufft pubblica la traduzione in tedesco della Bibbia, cui Martin Luther lavorava dal 1521. L’obiettivo dichiarato di Ickelsamer è aiutare i tedeschi a imparare a leggere la propria lingua, presumibilmente anche per poter leggere la Bibbia: Ain Teütsche Grammatica/Darauß einer von jm selbs mag lesen lernen. Ickelsamer condivide con i grammatici tedeschi contemporanei e successivi l’obiettivo prioritario di costruire un sistema linguistico tedesco autonomo e fortemente identitario, affrancato da quello latino. Tuttavia il suo approccio pedagogico anticipa sorprendentemente, ovviamente solo sul piano dell’intuizione, future scoperte di natura glottodidattica e neurobiologica.

The model, which incorporates a hydrodynamic description of the quark-gluon plasma with a kinetic approach of hadron cascades, is applied to analysis of elliptic flow data at the Relativistic Heavy Ion Collider energy. It is predicted that the elliptic flow parameter based on the hybrid model increases with the collision energy up to the Large Hadron Collider energy.

description: In multi-agent applications such as surveillance and logistics, fleets of mobile agents are often expected to coordinate and safely visit a large number of goal locations as efficiently as possible. The multi-agent planning problem in these applications involves allocating and sequencing goals for each agent while simultaneously producing conflict-free paths for the agents. In this article, we introduce a new algorithm called MS* which computes an optimal solution for this multi-agent problem by fusing and advancing state of the art solvers for multi-agent path finding (MAPF) and multiple travelling salesman problem (mTSP). MS* leverages our prior subdimensional expansion approach for MAPF and embeds the mTSP solvers to optimally allocate and sequence goals for agents. Numerical results show that our new algorithm can solve the multi-agent problem with 20 agents and 50 goals in a minute of CPU time on a standard laptop.

description: The generic band structure of high-T$_C$ copper oxides is simulated by the nearly free-electron model (NFE) in two dimensions (2-D) with parameters from band calculations. Interaction between phonons and spin waves will cause potential modulations and pseudogaps, and the strength of the modulations, the wave lengths and the doping, are all related. A Fermi-surface "arc" is found for dynamic spin/phonon waves. The confinement of superconductivity between two limiting dopings can be a result of competition with the pseudogap at low doping and weak coupling at high doping.

description: We extend Kodama-Ishibashi and Jansen-Rostworowski-Rutkowski master field framework to study quasinormal modes of black branes and black holes of Einstein gravity in $D=5$ space-time dimensions with multiple scalars and an arbitrary bulk potential. As an application, we consider a thermodynamically unstable state of mass deformed ${\cal N}=4$ supersymmetric Yang-Mills theory at strong coupling. The corresponding gravitational dual is ${\cal N}=2^*$ black brane with a dynamical instability of its translationary invariant horizon. We study the dependence of the quasinormal mode spectra as the boundary gauge theory is compactified on $S^3$ -- the black brane is turned into the black hole.

In addition, the same protocol is shown to be able to transfer the W state from one row to the other.

description: By modulating the intensity of laser light before the rotating groundglass, the well-known pseudothermal light source can be modified into superbunching pseudothermal light source, in which the degree of second-order coherence of the scattered light is larger than 2. With the modulated intensities following binary distribution, we experimentally observed the degree of second- and third-order coherence equaling 20.45 and 227.07, which is much larger than the value of thermal or pseudothermal light, 2 and 6, respectively. Numerical simulation predicts that the degree of second-order coherence can be further improved by tuning the parameters of binary distribution. It is also predicted that the quality of temporal ghost imaging can be improved with this superbunching pseudothermal light. This simple and efficient superbunching pseudothermal light source provides an interesting alternative to study the second- and higher-order interference of light in these scenarios where thermal or pseudothermal light source were employed.

description: Η διδακτορική διατριβή “Διαλεκτικά στοιχεία της Απουλίας και των Βασιλικάτων” εστιάζει στα διαλεκτικά στοιχεία ελληνικής και ρωμανικής προέλευσης των ιταλικών διαλέκτων και ιδιωμάτων της Απουλίας και των Βασιλικάτων, με αναφορές στην ιστορική γλωσσολογία, την ανθρωπολογία και την ονοματολογία (τοπωνύμια). Η πορεία των διαλέκτων της Απουλίας και των Βασιλικάτων χαρακτηρίζεται από μια αμφίδρομη σχέση, η οποία ξεκινά από την εποχή των ελληνικών αποικιών της Μεγάλης Ελλάδας και ολοκληρώνεται τον 15ο αι. μ. Χ., ενώ συγχρόνως γίνεται αναφορά στην σημερινή τους καταστάση και στην κατάσταση της ιταλικής γλώσσας. Αντικείμενο της παρούσας έρευνας είναι η μελέτη των διαλέκτων της Απουλίας και των Βασιλικάτων (δηλ. η αναζήτηση και η καταγραφή των λεξιλογικών όρων, η σύγκρισή τους με αντίστοιχους όρους, οι οποίοι απαντούν στις αρχαίες ιταλικές και στις σύγχρονες ιταλικές διαλέκτους καθώς και στην Aρχαία, Mεσαιωνική και Nέα Eλληνική). Μέσα από την παρουσίαση των διαλεκτικών στοιχείων γίνεται αναφορά στο χορευτικό φαινόμενο (ταραντέλα) καθώς και στην σχέση γλώσσας και χορού, με αναφορά στην ετυμολογία των όρων χορός, danza, ballo. Για την μελέτη των διαλεκτικών στοιχείων χρησιμοποιείται η ιστορική – φιλολογική μέθοδος έρευνας, η διαχρονική και ανθρωπολογική προσέγγιση, η θεωρία Sapir – Whorf (Hypothesis of Linguistic Relativity), η μέθοδος της γλωσσογεωγραφίας και η μέθοδος της συμμετοχικής παρατήρησης.
description: The doctoral thesis "Dialectal Elements of Apulia and Basilicata" focuses on dialectic items Greek and Romance origin in the Italian dialects and idioms of Puglia and Basilicata, with references to historical linguistics, anthropology and nomenclature (place names/ toponyms). The course of the dialects of Apulia and Basilicata is characterized by a two-way relationship, which begins at the time of the Greek colonies of Magna Grecia and is completed in the 15th century AD. In the thesis there is also a reference on the present status of Apulia and Basilicata dialects and also of the Italian language The purpose of this research is the study of the dialects of Apulia and Basilicata (i.e. Search and registration of lexical terms, comparison with the respective conditions, which occur in the ancient and modern Italian dialects and in the Ancient, Medieval and New Greek language). Through the presentation of the dialectical data, a special reference is also made to the phenomenon of dance (tarantella) and to the relationship between language and dance, by the presentation of the etymology of dance terms, such as: χορός, dance, danza, ballo. For the study of dialectal elements are used the following methods: 1.The Historical - Philological Method 2. The Diachronic and Anthropological approach 3. The Sapir – Whorf Theory (Hypothesis of Linguistic Relativity) 4. The method of Linguistic Geography 5. The method of Participatory Observation.
Friction as a probe of surface properties of a polymer glass

description: We probe the temperature dependence of friction at the interface between a glassy poly(methylmethacrylate) lens and a flat substrate coated with a methyl-terminated self-assembled monolayer. The monolayer exhibits density defects which act as pinning sites for the polymer chains. We show that the shear response of such an interface supports the existence, at the surface of the glassy polymer, of a nanometer-thick layer of mobile chains. Friction can be ascribed to the interplay between viscouslike dissipation in this layer and depinning of chains adsorbed on the substrate. We further show that the pinning dynamics is controlled by βrotational motions localized at the interface.

description: We perform a Hadamard point-split renormalization of the current density $j_ν$ of a charged scalar field in a Reissner-Nordström-de Sitter spacetime. We compute numerically the expectation values of the components $j_r$ and $j_t$ in the Unruh state in the exterior region and study their dependence on the field parameters and the position.

description: What is presented in this Ph.D. dissertation is a complete proposal of planning and implementing a Language Program for the development of skills necessary for foreign students during their studies at the Greek university. The substantiation of the proposal is based on the international and Greek bibliography and on the results of Language Needs Analysis of foreign students studying at the B’ Semester of Schools and Departments of the Aristotle University of Thessaloniki and at the School of Modern Greek Language. An ad hoc syllabus and teaching material based on the results of Needs Analysis was designed for the Language Program for the academic use of Greek as a foreign language (63 hours). The Program was implemented in three stages and its evaluation during all stages of the implementation established its effectiveness.The Program is regarded as a useful base which can be considered in planning courses for the expansion of skills necessary for the academic use of Greek as a foreign language.
Kerr-Schild Double Copy of the Coulomb Solution in Three Dimensions

description: While the Kerr-Schild double copy of the Coulomb solution in dimensions higher than three is the Schwarzschild black hole, it is known that it should be a non-vacuum solution in three dimensions. We show that the static black hole solution of Einstein-Maxwell theory (with one ghost sign in the action) is the double copy with the correct Newtonian limit, which provides an improvement over the previous construction with a free scalar field that does not vanish at infinity. By considering a negative cosmological constant, we also study the charged Bañados-Teitelboim-Zanelli black hole and find that the single copy gauge field is the Coulomb solution modified by a term which describes an electric field linearly increasing with the radial coordinate, which is the usual behaviour of the Schwarzschild-AdS black hole in higher dimensions when written around a flat background metric.

description: The conductivity of graphene samples with various levels of disorder is investigated for a set of specimens with mobility in the range of $1-20\times10^3$ cm$^2$/V sec. Comparing the experimental data with the theoretical transport calculations based on charged impurity scattering, we estimate that the impurity concentration in the samples varies from $2-15\times 10^{11}$ cm$^{-2}$. In the low carrier density limit, the conductivity exhibits values in the range of $2-12e^2/h$, which can be related to the residual density induced by the inhomogeneous charge distribution in the samples. The shape of the conductivity curves indicates that high mobility samples contain some short range disorder whereas low mobility samples are dominated by long range scatterers.

description: Twists are defects in the lattice that can be used to perform encoded computations. Three basic types of twists can be introduced in color codes, namely, twists that permute color, charge of anyons and domino twists that permute the charge label of an anyon with a color label. In this paper, we study a subset these twists from coding theoretic viewpoint. Specifically, we discuss systematic construction of charge permuting and color permuting twists in color codes. We show that by braiding alone, Clifford gates can be realized in color codes with charge permuting twists. We also discuss implementing single qubit Clifford gates by Pauli frame update and CNOT gate by braiding holes around twists in color codes with color permuting twists. Finally, we also discuss implementing a non-Clifford gate by state injection, thus completing the realization of a universal gate set.
Vertical restraints in the distribution process under New Zealand competition law
Creators: name: Moorman, David Guy
Publisher: name: University of British Columbia
Year: 2010

description: The law relating to vertical restraints in the distribution process has sparked probably more controversy than any other area of competition law over the last 20 years. The debate has been fought out most fiercely between economists of various ideological schools invoking arguments of the importance of economic efficiency versus the need to protect small businesses and the freedom of sellers to choose their own methods of distribution. This has generated an extensive body of literature particularly in the United States. Surprisingly little however has been written in Australia or New Zealand on this subject. This thesis attempts to fill the void, although, in so doing, it does not seek to delve into the technical and complex aspects of law and economics in this area. Rather, it seeks merely to raise the basic issues in the New Zealand context from which base a more sophisticated study can subsequently be undertaken. By way of introduction, the nature of vertical restraints in the distribution process are described and some background is provided to the areas of debate. The thesis then breaks up into two parts to examine the current state of the law in the United States, Canada, Australia and New Zealand in respect of, first, vertical price restraints and, second, vertical non-price restraints. Where appropriate, a comparative analysis is made to shed light on the interpretation of key words and phrases in the New Zealand legislation. In respect of each type of restraint, the basic economic issues involved are then canvassed, given the strategic role which economics plays in understanding why vertical restraints are imposed and their competitive effects. Thereafter, various legal and policy issues are discussed to assist in deciding upon the appropriate legal treatment of each type of restraint. Finally, an attempt is made to provide an analytically coherent framework within which to judge vertical restraints in the context of present competition policy. The conclusions reached call into question the present total prohibition against resale price maintenace in New Zealand and advocate the need for more specific provisions regarding both price and non-price vertical restraints. In particular, it is suggested that a rule of per se illegality should only operate for conduct which attempts to fix, maintain or control the price at which products are resold, while a structured rule of reason should operate for all other types of vertical restraints based on a market power test administered in accordance with guidelines promulgated by the Commerce Commission.
Half-Quantum Vortices in Nematic and Chiral Phases of $^3$He

description: We report theoretical results for the stability of half-quantum vortices (HQVs) in the superfluid phases of $^3$He confined in highly anisotropic Nafen aerogel. Superfluidity of $^3$He confined in Nafen is the realization of a "nematic superfluid" with Cooper pairs condensed into a single p-wave orbital aligned along the anisotropy axis of the Nafen aerogel. In addition to the nematic phase, we predict a second "chiral" phase that onsets at a lower transition temperature. This chiral phase spontaneously breaks time-reversal symmetry and is a topological superfluid. Both superfluid phases are equal-spin pairing condensates that host arrays of HQVs as equilibrium states of rotating superfluid $^3$He. We present results for the structure of HQVs, including magnetic and topological signatures of HQVs in both the nematic and chiral phases of $^3$He-Nafen.
