description: The CNOT gate is a two-qubit gate which is essential for universal quantum computation. A well-established approach to implement it within Majorana-based qubits relies on subsequent measurement of (joint) Majorana parities. We propose an alternative scheme which operates a protected CNOT gate via the holonomic control of a handful of system parameters, without requiring any measurement. We show how the adiabatic tuning of pair-wise couplings between Majoranas can robustly lead to the full entanglement of two qubits, insensitive with respect to small variations in the control of the parameters.

description: In this text we give a decomposition result on polynomial poly-vector fields generalizing a result on the decomposition of homogeneous Poisson structures. We discuss consequences of this decomposition result in particular for low dimensions and low degrees. We provide the tools to calculate simple cubic Poisson structures in dimension three and quadratic Poisson structures in dimension four. Our decomposition result has a nice effect on the relation between Poisson structures and Jacobi structures.

description: We present the results of a search of the XMM-Newton public data archive for stellar X-ray flares. We find eight flaring sources for which we identify 7 optical counterparts. Three of these sources have distance estimates which allow us to determine their luminosities. Based on the decay time of the flares and their luminosity we derive loop half-lengths of ~2-7x10^10 cm and emission measures of ~10^54 cm^-3: these are similar to values derived for other stellar flaring sources. One of the stars shows two flares in close succession. We discuss the likelihood of this double event being either sympathetic or homologous in nature. A comparison to a pair of similar flares on the Sun suggests that homology is the more likely process driving the flare event.

title: Understanding the structure and role of academics' ego-networks on social networking sites
Creators: name: Jordan, Katherine Lucy
Publisher: name: The Open University
Year: 2017

description: Academic social networking sites (SNS) seek to bring the benefits of online networking to an academic audience. Currently, the two largest sites are Academia.edu and ResearchGate. The ability to make connections to others is a defining affordance of SNS, but what are the characteristics of the network structures being facilitated by academic SNS, and how does this relate to their professional use by academics? This study addressed this question through mixed methods social network analysis. First, an online survey was conducted to gain contextual data and recruit participants (n = 528). Second, ego-networks were drawn up for a sub-sample of 55 academics (reflecting a range of job positions and disciplines). Ego-networks were sampled from an academic SNS and Twitter for each participant. Third, co-interpretive interviews were held with 18 participants, to understand the significance of the structures and how the networks were constructed. Academic SNS networks were smaller and more highly clustered; Twitter networks were larger and more diffuse. Communities within networks are more frequently defined by institutions and research interests on academic SNS, compared to research topics and personal interests on Twitter. Emerging themes link network structure to differences in how academics conceptualise and use the sites. Academic SNS are regarded as a more formal academic identity, akin to a business card, or used as a personal repository. Twitter is viewed as a space where personal and professional are mixed, similar to a conference coffee break. Academic SNS replicate existing professional connections, Twitter reinforces existing professional relationships and fosters novel connections. Several strategies underpinning academics’ use of the sites were identified, including: circumventing institutional constraints; extending academic space; finding a niche; promotion and impact; and academic freedom. These themes also provide a bridge between academic identity development online and formal academic identity and institutional roles.
Patching the holes of the city : an urban design framework for redevelopment of Arbutus-Broadway and nearby 21 blocks
Creators: name: Liu, Xue
Publisher: name: University of British Columbia
Year: 2010

description: Vacant, skipped-over or underused parcels of land in otherwise built-up environment can be identified in every city. These undeveloped or underutilized parcels of land are like "holes" of our city fabric. As the demand for new housing and services grows in urban areas, great opportunities and spaces for future developments are availed. The means to revitalize these "holes" in our dynamic city have gained more and more attention from the public. Theoretical responses have come through a long way from Modernism, to Postmodernism, Gentrification, and now New Urbanism. Even though new urbanism was originally an alternative to suburban sprawl, it provides existing urban built areas a broader vision of re-urbanization that crosses scales of Region, District, Neighborhood, and Block to Building. Sharing the similarities with the City of Vancouver’s urban design ideology, New Urbanism is the theoretical basis for this project. It specifies the study within Kitsilano East area, and to create an urban design framework that cross overlays of Open Space, Circulation and Urban Fabric. New Urbanism also provides the theoretical context through the following site planning and site design of Arbutus-Broadway and its nearby 21 blocks. This thesis project is hoped to be a drop in the sea that pushes the urban redevelopment wave forward while it creates a mixed-use, vibrant Arbutus-Broadway area, and supports its role in the city as a whole.

description: For conventional topological phases, the boundary gapless modes are determined by bulk topological invariants. Based on developing an analytic method to solve higher-order boundary modes, we present $PT$-invariant $2$D topological insulators and $3$D topological semimetals that go beyond this bulk-boundary correspondence framework. With unchanged bulk topological invariant, their first-order boundaries undergo transitions separating different phases with second-order-boundary zero-modes. For the $2$D topological insulator, the helical edge modes appear at the transition point for two second-order topological insulator phases with diagonal and off-diagonal corner zero-modes, respectively. Accordingly, for the $3$D topological semimetal, the criticality corresponds to surface helical Fermi arcs of a Dirac semimetal phase. Interestingly, we find that the $3$D system generically belongs to a novel second-order nodal-line semimetal phase, possessing gapped surfaces but a pair of diagonal or off-diagonal hinge Fermi arcs.

Chaos and ergodicity in an entangled two-qubit Bohmian system

description: We study in detail the onset of chaos and the probability measures formed by individual Bohmian trajectories in entangled states of two-qubit systems for various degrees of entanglement. The qubit systems consist of coherent states of 1-d harmonic oscillators with irrational frequencies. In weakly entangled states chaos is manifested through the sudden jumps of the Bohmian trajectories between successive Lissajous-like figures. These jumps are succesfully interpreted by the `nodal point-X-point complex' mechanism. In strongly entangled states, the chaotic form of the Bohmian trajectories is manifested after a short time. We then study the mixing properties of ensembles of Bohmian trajectories with initial conditions satisfying Born's rule. The trajectory points are initially distributed in two sets $S_1$ and $S_2$ with disjoint supports but they exhibit, over the course of time, abrupt mixing whenever they encounter the nodal points of the wavefunction. Then a substantial fraction of trajectory points is exchanged between $S_1$ and $S_2$, without violating Born's rule. Finally, we provide strong numerical indications that, in this system, the main effect of the entanglement is the establishment of ergodicity in the individual Bohmian trajectories as $t\to\infty$: different initial conditions result to the same limiting distribution of trajectory points.

description: The aim of this paper is to construct comodules of $U_q(sl_2)$ and modules of $SL_q(2)$ via quiver, where $q$ is not a root of unity. By embedding the quantized algebra $U_q(sl_2)$ into the path coalgebra $k\mathcal{D}^c$, where $\mathcal{D}$ is the Gabriel quiver of $U_q(sl_2)$ as a coalgebra, we obtain a basis of $U_q(sl_2)$ in terms of combinations of paths in the quiver $\mathcal{D}$; this special basis enable us to describe the category of $U_q(sl_2)$-comodules by certain representations of $\mathcal{D}$; and this description further permits us to construct a class of modules of the quantum special linear group $SL_q(2)$, from certain representations of $\mathcal{D}$, via the duality between $U_q(sl_2)$ and $SL_q(2)$.

The effects of short term voluntary exercise in isolated animals
Creators: name: Webber, Alina Jane
Publisher: name: University of British Columbia
Year: 2010

description: Voluntary exercise has been shown to consistently increase proliferation and neurogenesis in the dentate gyrus. Recently it was reported that social isolation can counteract the effects of voluntary exercise on cell proliferation and neurogenesis in the dentate gyrus of the hippocampus. We examined the effects of social isolation on animals engaging in voluntary exercise, looking at adult male C57BL/6J mice. Animals in this study were isolated for 1 week and then placed in their respective housing conditions. Exercise wheels were quasi-randomly assigned to cages, and animals were left in this environment for 11 days. On the 12th day, 5-bromo-2-deoxyuridine (BrdU) was injected as a marker of dividing cells. Animals were sacrificed 2 hours later to measure cell proliferation. We found no significant effects of social isolation on cell proliferation. In contrast, voluntary exercise nearly doubled the number of BrdU labeled cells regardless of the animals housing situation. The number of cells positive for doublecortin, (DCX), a protein found specifically in immature neurons, also significantly increased in response to voluntary exercise. Social isolation did not have a significant effect on this measure, and voluntary exercise, rather than social housing was also found to increase the complexity of the processes of immature neurons labeled by DCX. In addition, a pilot study in aged mice indicated that even aged animals that have been isolated for more prolonged periods of time have a greater survival of BrdU labeled cells in response to voluntary exercise, although this was a non significant trend.

description: A detailed theoretical framework for highly excited Rydberg molecules is developed based on the generalized local frame transformation. Our approach avoids the use of pseudopotentials and yields analytical expressions for the body-frame reaction matrix. The latter is used to obtain the molecular potential energy curves, but equally it can be employed for photodissociation, photoionization, or other processes. To illustrate the reliability and accuracy of our treatment we consider the Rb$^*-$Rb Rydberg molecule and compare our treatment with state-of-the-art alternative approaches. As a second application, the present formalism is used to re-analyze the vibrational spectra of Sr$^*-$Sr molecules, providing additional physical insight into their properties and a comparison of our results with corresponding measurements.

Subjects: subject: Other Condensed Matter (cond-mat.other)

description: We present a theoretical analysis of the evaporative cooling of a magnetically guided atomic beam by means of discrete radio-frequency antennas. First we derive the changes in flux and temperature, as well as in collision rate and phase-space density, for a single evaporation step. Next we show how the occurrence of collisions during the propagation between two successive antennas can be probed. Finally, we discuss the optimization of the evaporation ramp with several antennas to reach quantum degeneracy. We estimate the number of antennas required to increase the phase-space density by several orders of magnitude. We find that at least 30 antennas are needed to gain a factor $10^8$ in phase-space density.

MPF will employ a 1.1m aperture telescope, which images a 1.3 sq. deg. field-of-view in the near-IR, in order to detect extrasolar planets with the gravitational microlensing effect. MPF's sensitivity extends down to planets of 0.1 Earth masses, and MPF can detect Earth-like planets at all separations from 0.7AU to infinity. MPF's extrasolar planet census will provide critical information needed to understand the formation and frequency of extra solar planetary systems similar to our own.

description: We study a transverse momentum dependent (TMD) factorization framework for the processes of di-jet and heavy meson pair production in deep-inelastic-scattering in an electron-proton collider, considering the measurement of the transverse momentum imbalance of the two hard probes in the Breit frame. For the factorization theorem we employ soft-collinear and boosted-heavy-quark effective field theories. The factorized cross-section for both processes is sensitive to gluon unpolarized and linearly polarized TMD distributions and requires the introduction of a new soft function. We calculate the new soft function here at one loop, regulating rapidity divergences with the $δ$-regulator. In addition, using a factorization consistency relation and a universality argument regarding the heavy-quark jet function, we obtain the anomalous dimension of the new soft function at two loops.

description: A tanulmány célja, hogy a magyar és a lengyel élő szarvasmarha és marhahús külkereskedelmet megvizsgálja, az EU27 piacán. A különböző számított mutatók a komparatív előnyöket és -hátrányokat, valamint a versenyképességet vizsgálják több aspektusból. Magyarország exportját megvizsgálva komparatív, vagy versenyhátrányt jeleznek az indexek, mivel a referencia országokhoz képest elmarad kivitelünk minkét termék esetén. Lengyelországban azonban komparatív- és versenyelőnyt mutattak csatlakozásuk után a mutatók, mivel magasan az átlagos mennyiség felett exportáltak marhahúst. Egy tekintetben megegyeztek mind a magyar, mind a lengyel számítások: az export átlagár a csatlakozást követően az import átlagár alá csökkent, és ezt csak a válság után sikerült Magyarország esetében egyedül 2011-ben, Lengyelország esetében viszont 2011-2013-ban megfordítani. Az alkalmazott indexek alapján kijelenthető, hogy Lengyelország egyértelmű nyertese az EU csatlakozásnak a szarvasmarha és marhahús külkereskedelmét tekintve. Magyarország esetében azonban összetettebb a helyzet, a csatlakozás nem hozta meg a remélt nagymértékű fellendülést, a válság pedig rossz helyzetbe hozta az élő szarvasmarha és marhahús külkereskedelmünket. --------------------------------------------- The aim of this study was to examinate the foreign trade of live beef cattle and beef of Hungary and Poland in the EU27 market. This analysis based on various calculated indexes which indicate the comparative advantages and disadvantages, as well as competitiveness in different aspects. Indexes of Hungarian export show comparative and competitive disadvantages because Hungarian export is lower than in reference countries (EU average). Oppositely, there are comparative and competitive advantages in Poland because of the higher beef export than EU average. Accessorily Hungarian and Polish indexes show the same trend in one case: the average export price become lower than the average import price after EU connection. This value could turn back in only year (2011) in Hungary and in a three year period (2011-2013) in Poland. Summarized results Poland could profit by the EU connection on foreign trade of live beef cattle and beef. The position of Hungary could not get better. The EU connection had not made expected recoveries and later the financial crisis prejudiced the success of Hungarian foreign trade of live beef cattle and beef.

description: Kelet-Közép-Európa térszerkezete szemmel is látható és adatokban is tapasztalható változásokon megy át az utóbbi évtizedekben. A politikai rendszerváltás, a gazdasági szerkezetváltás, az EU-hoz való csatlakozás és intézményi közeledés kiegyenlítetlenül hat a globalizáció által is érintett területre. Az Európai Unió területi fejlesztési politikájának meghatározó eleme a városi terek fejlesztése. A tanulmányban két EU-s tagállam, Románia és Németország városfejlesztési tapasztalatai olvashatók. Az integrált városfejlesztés legfontosabb ismertetőjegyeinek bemutatása után arra térek ki, hogy milyen korlátai maradtak napjainkra is az alkalmazott szemléletnek. A tanulmány mindkét ország esetében bemutatja, hogy melyek azok a konkrét városrégióhoz köthető tapasztalatok, amelyek a leginkább megfeleltethetők az elméleti részben ismertetett elméleti és közösségi dokumentációs háttérnek. Az előzetes várakozásoknak megfelelően a nyugat-európai ország esetében sokkal erőteljesebb szerepet játszanak a városfejlődés előmozdításában az üzleti és civil szféra szereplői. Romániában meghatározóak a központi kormányzat által megfogalmazott perspektivikus tervdokumentumok. --------------------------------------------- The spatial structure of the macro region of Eastern-Central-Europe is producing great changes in the quantitative sphere, but these changes are also viable by our eyes. The change of the political system, the changes in the economic structure and output, the EU-accession, and the institution building issue causes an unbalanced process in these cases. There is a great deal of theoretical knowledge and empirical data in the field of the economic growth and its connections with the spatial structure. The development of urban spaces is a key element of the regional policy of the European Union. The paradigms of the integrated urban development have got also constraints in the study I mention some of them. In the study are two EU-member state’s urban development experiments to read. The work presents, for each country, what are the specific city region related experiences, which most correspond to the theoretical background and Community Documentation. Matching the preliminary expectations in the case of the western European country, the actors of the business and civic sphere play a much stronger role in the urban development. In the development practice of Romania, the plan documents are prominent, which are formulated by the members of the central government.

Nous nous intéressons en particulier aux conditions théoriques qui garantissent un impact positif des Systèmes d’Information de Marché (SIM) sur les termes de l’accord et l’efficience du marché. Nous testons ensuite empiriquement les prédictions du modèle théorique à l’aide de données originales collectées au Nord du Ghana. Nos résultats montrent un impact significatif du SIM sur les utilisateurs : en 2009 ils ont vendu en moyenne leur production 10 % plus chère pour le maïs et 7 % pour l’arachide.

description: Radio wavelength observations of solar system bodies reveal unique information about them, as they probe to regions inaccessible by nearly all other remote sensing techniques and wavelengths. As such, the SKA will be an important telescope for planetary science studies. With its sensitivity, spatial resolution, and spectral flexibility and resolution, it will be used extensively in planetary studies. It will make significant advances possible in studies of the deep atmospheres, magnetospheres and rings of the giant planets, atmospheres, surfaces, and subsurfaces of the terrestrial planets, and properties of small bodies, including comets, asteroids, and KBOs. Further, it will allow unique studies of the Sun. Finally, it will allow for both indirect and direct observations of extrasolar giant planets.

description: We explore the topological properties of non-Hermitian nodal-link semimetals with dissipative cold atoms in a three-dimensional optical lattice. We construct a two-band continuum model in three dimensions with a spin-dependent gain and loss, where the exceptional points in the energy spectrum can comprise a double Hopf link. The topology of the bulk band is characterized by a winding number defined for a one-dimensional loop in the momentum space and a topological transition of the nodal structures emerges as the change of the non-Hermiticity strength. A non-Bloch theory is built to describe the corresponding lattice model which has anomalous bulk-boundary correspondence. Furthermore, we propose that the model can be realized using ultracold fermionic atoms in an optical lattice and the exceptional nodal links as well as the topological properties can be detected by measuring the atomic spin textures.

Feng Menglong and Hou Huiqing : records of anguish in fiction and song
Creators: name: Loo, Courtney Erin
Publisher: name: University of British Columbia
Year: 2010

description: This thesis seeks to examine Feng Menglong’s (1574-1646) relationship with the courtesan, Hou Huiqing, in light of the ideological and social tensions of late Ming culture. Though romances between scholars and courtesans is not a new topic in the study of Chinese literature, I seek to explore a more personal side of Feng by analyzing his lesser-known collections of song poetry, specifically narrative sanqu in Taixia xinzou (Celestial Airs Played Anew, 1627). The study of these poems is important because they represent the only surviving song suites of Feng’s - a total of sixteen sets. I am centrally concerned with the representation of failed love affairs in song poetry, as seen through Feng’s personal experiences and the experiences of his close literati friends. In analyzing his collections of fiction and song, I seek to establish a relationship between Feng’s writings on scholar-courtesan romance and his valorization of zhenqing, or "genuine sentiment". Though romantic love and genuine emotion are central preoccupations of Feng writings, they do not retain the same degree of importance throughout the different genres of his works. I argue that there is a great divide between the public themes of Feng’s fiction and the private sentiment of his songs. Feng’s songs are not only "private and particular," but they are remarkable for their intensely emotional tone, articulated from a male perspective rather than being projected onto the figure of the woman who is jilted by her male lover. In fiction however, Feng’s depiction of scholars and courtesans reverts to a more conventional morality. In stories published after his separation from Hou, Feng sought to put traditional hierarchies in critical perspective but did not advocate a complete break from the traditional social order.

description: This Reply to preceding Comment of arXiv:1909.09867 shows why the statements in the Comment are misleading. We point out that our physical picture and theirs are fundamentally different, therefore the claim of using their correlation to include ours shows a very limited physical relevance, which instead may impede the precise understanding of either of the two pictures.

description: We review some recent experimental progresses concerning Foundations of Quantum Mechanics and Quantum Information obtained in Quantum Optics Laboratory "Carlo Novero" at IENGF. More in details, after a short presentation of our polarization entangled photons source (based on precise superposition of two Type I PDC emission) and of the results obtained with it, we describe an innovative double slit experiment where two degenerate photons produced by PDC are sent each to a specific slit. Beyond representing an interesting example of relation between visibility of interference and "welcher weg" knowledge, this configuration has been suggested for testing de Broglie-Bohm theory against Standard Quantum Mechanics. Our results perfectly fit SQM results, but disagree with dBB predictions. Then, we discuss a recent experiment addressed to clarify the issue of which wave-particle observables are really to be considered when discussing wave particle duality. This experiments realises the Agarwal et al. theoretical proposal, overcoming limitations of a former experiment. Finally, we hint to the realization of a high-intensity high-spectral-selected PDC source to be used for quantum information studies.

description: The electromagnetic form factors of the proton are obtained using a particular realization of QCD in the large $N_c$ limit (${QCD}_{\infty}$), which sums up the infinite number of zero-width resonances to yield an Euler's Beta function (Dual-${QCD}_{\infty}$). The form factors $F_1(q^2)$ and $F_2(q^2)$, as well as $G_M(q^2)$ agree very well with reanalyzed space-like data in the whole range of momentum transfer. In addition, the predicted ratio $μ_p G_E/G_M$ is in good agreement with recent polarization transfer measurements at Jefferson Lab.

description: We discuss the Hartree equation arising in the mean-field limit of large systems of bosons and explain its importance within the class of nonlinear Schroedinger equations. Of special interest to us is the Hartree equation with focusing nonlinearity (attractive two-body interactions). Rigorous results for the Hartree equation are presented concerning: 1) its derivation from the quantum theory of large systems of bosons, 2) existence and stability of Hartree solitons, and 3) its point-particle (Newtonian) limit. Some open problems are described.

Mesonic states and vacuum replicas in potential quark models for QCD

description: In this paper, we study generic non-local NJL models for four-dimensional QCD in the limit of a large number of colours. We diagonalise, through a Bogoliubov-type transformation, the Hamiltonian of the model completely in terms of the compound operators creating/annihilating mesons - bound states of dressed quarks and antiquarks - and demonstrate a one-to-one correspondence between the Bogoliubov diagonalisation condition and the Bethe-Salpeter equation for bound states. We conclude that, in the leading order in N_C, the nontrivial contents of the theory is entirely encoded in the chiral angle - the solution to the mass-gap equation for dressed quarks. As a consequence, we extend the statement of existence of excited solutions to the mass-gap equation, called vacuum replicas, beyond the BCS level and prescribe a new index to the mesonic operators - the label of the vacuum state in which the corresponding meson is created.

Irradiation of accretion discs in active galactic nuclei due to warm absorber

description: The presence of the warm absorber of considerable optical depth is seen in many AGN. We show that this medium may affect significantly the optical/UV spectrum of an AGN by backscattering a fraction of the total radiation flux towards the disc surface. We consider in detail the case when the disk extends down to a marginally stable orbit, all the emission comes from the disk surface and the scattering medium forms a cone around the symmetry axis. Disc irradiation results in much flatter optical/UV continuum than predicted by standard disc models. The effect depends both on the total optical depth of the warm absorber and on the specific density distribution of this medium so the analysis of the optical/UV continuum allows to obtain constraints for the warm absorber complementary to those obtained from the soft X-ray data analysis. We give results for two exemplary sources - RE J1034+396 and PG1211+143, and for the bluest composite quasar spectrum of Richards et al. obtained from SDSS.
