description: By a classical theorem of Gallot (1979), a Riemannian cone over a complete Riemannian manifold is either flat or has irreducible holonomy. We consider metric cones with reducible holonomy over pseudo-Riemannian manifolds. First we describe the local structure of the base of the cone when the holonomy of the cone is decomposable. For instance, we find that the holonomy algebra of the base is always the full pseudo-orthogonal Lie algebra. One of the global results is that a cone over a compact and complete pseudo-Riemannian manifold is either flat or has indecomposable holonomy. Then we analyse the case when the cone has indecomposable but reducible holonomy, which means that it admits a parallel isotropic distribution. This analysis is carried out, first in the case where the cone admits two complementary distributions and, second for Lorentzian cones. We show that the first case occurs precisely when the local geometry of the base manifold is para-Sasakian and that of the cone is para-Kählerian. For Lorentzian cones we get a complete description of the possible (local) holonomy algebras in terms of the metric of the base manifold.

Canadian provincial and territorial archival legislation : a case study of the disjunction between theory and law
Creators: name: Bryans, Victoria Louise
Publisher: name: University of British Columbia
Year: 2010

description: This thesis is an inquiry into the nature of current provincial and territorial archival legislation in Canada. It provides an analysis of archival legislation as a form of written communication and argues that the legislation suffers from the same deficiencies inherent in other forms of communication as a result of external social influences on its meaning. Chapter one therefore traces the evolution of the legislation from 1790 to the present and shows how the meaning of current legislative texts emerged neither from objective legal considerations nor archival theory, but as an ad hoc response to a variety of social influences. The remaining chapters are based on a detailed content analysis of the three main components of current provincial and territorial archival legislation: provisions establishing definitions of key terms, provisions establishing the scope and authority of administrative structures for archival programmes and provisions establishing programme elements. They elaborate on the argument advanced in chapter one that the social production of meaning, arising from the manner in which current provincial and territorial archival legislation has developed, adversely affects its ability to promote the preservation of documents in two ways. First, this process of development has meant that wording in legislative texts carries overtones of outdated attitudes and assumptions about archives. Second, it has led to inconsistency, conflict, vagueness and ambiguity in the meaning of the texts. These chapters also put forth prescriptive ideas regarding how the adverse affects of social influences on the meaning of current provincial and territorial archival legislation might be overcome.

description: Metallic iridium oxides (iridates) provide a fertile playground to explore new phenomena resulting from the interplay between topological protection, spin-orbit and electron-electron interactions. To date, however, few studies of the low energy electronic excitations exist due to the difficulty in synthesising crystals with sufficiently large carrier mean-free-paths. Here, we report the observation of Shubnikov-de Haas quantum oscillations in high-quality single crystals of monoclinic SrIrO$_3$ in magnetic fields up to 35~T. Analysis of the oscillations reveals a Fermi surface comprising multiple small pockets with effective masses up to 4.5 times larger than the calculated band mass. \textit{Ab-initio} calculations reveal robust linear band-crossings at the Brillouin zone boundary, due to its non-symmorphic symmetry, and overall we find good agreement between the angular dependence of the oscillations and the theoretical expectations. Further evidence of strong electron correlations is realized through the observation of signatures of non-Fermi liquid transport as well as a large Kadowaki-Woods ratio. These collective findings, coupled with knowledge of the evolution of the electronic state across the Ruddlesden-Popper iridate series, establishes monoclinic SrIrO$_3$ as a topological semimetal on the boundary of the Mott metal-insulator transition.
Why are accreting T Tauri stars observed to be less luminous in X-rays than non-accretors?

description: Accreting T Tauri stars are observed to be less luminous in X-rays than non-accretors, an effect that has been detected in various star forming regions. To explain this we have combined, for the first time, a radiative transfer code with an accretion model that considers magnetic fields extrapolated from surface magnetograms obtained from Zeeman-Doppler imaging. Such fields consist of compact magnetic regions close to the stellar surface, with extended field lines interacting with the disc. We study the propagation of coronal X-rays through the magnetosphere and demonstrate that they are strongly absorbed by the dense gas in accretion columns. The reduction in the observed X-ray emission depends on the field geometry, which may explain why accreting T Tauri stars show a larger scatter in their observed X-ray luminosity compared to non-accreting stars.

description: With the imminent advent of mesoscopic rotating BECs in the lowest Landau level (LLL) regime, we explore LLL vortex nucleation. An exact many-body analysis is presented in a weakly elliptical trap for up to 400 particles. Striking non-mean field features are exposed at filling factors >>1 . Eg near the critical rotation frequency pairs of energy levels approach each other with exponential accuracy. A physical interpretation is provided by requantising a mean field theory, where 1/N plays the role of Planck's constant, revealing two vortices cooperatively tunneling between classically degenerate energy minima. The tunnel splitting variation is described in terms of frequency, particle number and ellipticity.

description: Segmentlamellenholz (SLH) ist ein neuer Holzwerkstoff aus Fichtenholz, bestehend aus wechselseitig miteinander verklebten Trapezlamellen. Durch einen radialen Einschnitt der Stämme und eine der Trocknung vorausgehende Nassverklebung können die wesentlichen Prozessparameter, die bei der regulären Brettschichtholzherstellung für große Verluste hinsichtlich der Holzausbeute sorgen, deutlich verbessert werden. Die Holzausbeute wird so auf durchschnittlich 85 % gesteigert. Übereinander verklebte SLH-Lamellen bilden den Werkstoff Segmentschichtholz (SSH), der als Alternative zu Brettschichtholz (BSH) angesehen wird. Im Rahmen von Versuchen wurde die Biegefestigkeit von SLH und SSH experimentell bis zu Spannweiten von 6 m untersucht. Beide Produkte sind in der ETA-19/0832 geregelt und weisen eine minimale charakteristische Biegefestigkeit von f$_\text{m,k}$ = 24 N/mm² auf. Analog zu BSH ist es jedoch auch möglich, mit SSH große Spannweiten zu überbrücken. Um die Biegefestigkeiten von solchen Trägern abschätzen zu können, wurde ein Finite-Elemente-Modell, basierend auf dem Karlsruher Rechenmodell (KAREMO) sowie der Monte-Carlo-Methode, erstellt. Aufgrund der zweidimensionalen Verklebung innerhalb eines Querschnitts sowie der großen Lamellenhöhe sind im Gegensatz zu BSH wesentliche Änderungen in der Modellbildung notwendig. Die Trapezgeometrie der einzelnen Lamelle führt dazu, dass die für BSH gültigen Materialmodelle nicht verwendet werden können. In umfangreichen Versuchsreihen an kleinformatigen Prüfkörpern wurden daher die Materialeigenschaften sowie deren Korrelationen miteinander erfasst und in einem für SLH gültigen Materialmodell verarbeitet. Umfangreiche Simulationsstudien befassen sich mit den charakteristischen Biegefestigkeiten des Werkstoffs bei variierender Trägerhöhe und -breite. Abschließend werden Änderungen im Herstellungsprozess und deren Auswirkungen auf die Biegefestigkeiten mittels Simulationen untersucht.

description: We present the first result of the Ital-FLAMES survey of red giant branch (RGB) stars in omega Cen. Radial velocities with a precision of ~0.5 km/s are presented for 650 members of omega Cen observed with FLAMES-Giraffe at the Very Large Telescope. We found that stars belonging to the metal -poor (RGB-MP), metal-intemediate (RGB-MInt) and metal-rich (RGB-a) sub -populations of Omega Cen are all compatible with having the same rotational pattern. Our results appear to contradict past findings by Norris et al., who could not detect any rotational signature for metal -rich stars. The slightly higher precision of the present measurements and the much larger sample size, especially for the metal-richer stars, appear as the most likely explanation for this discrepancy. The result presented here weakens the body of evidence in favour of a merger event in the past history of omega Cen.

A critical guide to sources for the study of the history of the family in British Columbia, 1849-1918
Creators: name: Burrows, James Kenneth
Publisher: name: University of British Columbia
Year: 2010

description: Access to archival holdings is one of the fundamental problems faced by archivists. The difficulties in providing access to the wide variety of subjects contained with even one archives is further complicated by the changing fields of research which require the use of archives. Neither provenance based or subject indexing access systems have been able to cope with these changing needs. The creation of thematic guides has been an attempt to offer more flexible subject access to collections since each guide deals with a separate topic. Despite their value in providing access to current themes, the thematic guide has been simply a listing of collections and does not offer any analysis of how various forms of records, their availability and their uses relate to the subject. The creation of such a critical guide forms the bulk of the paper. To investigate the effectiveness of this type of guide, records which relate to the study of the history of the family in British Columbia were identified. This particular subject area was chosen because of its relative newness and since many of the records applicable to its study are not easily found. The holdings of the British Columbia Archives and Records Service and the City of Vancouver Archives provided the relevant materials for the study. The records chosen as useful to the study of the family were listed and many collections were examined closely. From this review of holdings, an analysis of records types and their value to the study of the family in British Columbia was developed. Standard appraisal and descriptive techniques were employed for the analysis. In addition, a study of past research uses was done to provide a better understanding of how the records could be employed. It was found that a critical guide could be produced using modifications of standard formats, such as the basic form for inventories suggested by the Society of American Archivists. In addition, appraisal criteria were applied to the categories of documents in order to assess their value. Using these standardized techniques means that an analysis of record types will be better understood by others. The critical guide offers a vehicle for archivists to provide researchers with more information about the records in a less haphazard fashion.

A formally exact field theory for classical systems at equilibrium

Year: 2007

description: We propose a formally exact statistical field theory for describing classical fluids with ingredients similar to those introduced in quantum field theory. We consider the following essential and related problems : i) how to find the correct field functional (Hamiltonian) which determines the partition function, ii) how to introduce in a field theory the equivalent of the indiscernibility of particles, iii) how to test the validity of this approach. We can use a simple Hamiltonian in which a local functional transposes, in terms of fields, the equivalent of the indiscernibility of particles. The diagrammatic expansion and the renormalization of this term is presented. This corresponds to a non standard problem in Feynman expansion and requires a careful investigation. Then a non-local term associated with an interaction pair potential is introduced in the Hamiltonian. It has been shown that there exists a mapping between this approach and the standard statistical mechanics given in terms of Mayer function expansion. We show on three properties (the chemical potential, the so-called contact theorem and the interfacial properties) that in the field theory the correlations are shifted on non usual quantities. Some perspectives of the theory are given.

description: The sparsity of multipaths in the wideband channel has motivated the use of compressed sensing for channel estimation. In this letter, we propose a different approach to sparse channel estimation. We exploit the fact that $L$ taps of channel impulse response in time domain constitute a non-orthogonal superposition of $L$ geometric sequences in frequency domain. This converts the channel estimation problem into the extraction of the parameters of geometric sequences. Numerical results show that the proposed scheme is superior to existing algorithms in high signal-to-noise ratio (SNR) and large bandwidth conditions.

description: Self-interacting Dark Matter (SIDM) is a leading candidate proposed to solve discrepancies between predictions of the prevailing cold dark matter theory and observations of galaxies. Many SIDM models predict the existence of a light force carrier that mediate strong dark matter self-interactions. If the mediator couples to the standard model particles, it could produce characteristic signals in dark matter direct detection experiments. We report searches for SIDM models with a light mediator using the full dataset of the PandaX-II experiment, based on a total exposure of 132 tonne-days. No significant excess over background is found, and our likelihood analysis leads to a strong upper limit on the dark matter-nucleon coupling strength. We further combine the PandaX-II constraints and those from observations of the light element abundances in the early universe, and show that direct detection and cosmological probes can provide complementary constraints on dark matter models with a light mediator.

For strong impurity scattering, near the unitary limit, the formation of a band of impurity states near the Fermi level leads to that Mott's relation holds at low temperature. For higher temperatures, there are strong deviations due to the linear density of states. The low-temperature thermopower is proportional to the inverse of the impurity potential and the inverse of the impurity density. Information about impurity scattering in graphene can be extracted from the thermopower, either measured directly, or extracted via Mott's relation from the electron-density dependence of the electric conductivity.

description: Integrable Floquet spin chains are known to host strong zero and $π$ modes which are boundary operators that respectively commute and anticommute with the Floquet unitary generating stroboscopic time-evolution, in addition to anticommuting with a discrete symmetry of the Floquet unitary. Thus the existence of strong modes imply a characteristic pairing structure of the full spectrum. Weak interactions modify the strong modes to almost strong modes that almost commute or anticommute with the Floquet unitary. Manifestations of strong and almost strong modes are presented in two different Krylov subspaces. One is a Krylov subspace obtained from a Lanczos iteration that maps the time-evolution generated by the Floquet Hamiltonian onto dynamics of a single particle on a fictitious chain with nearest neighbor hopping. The second is a Krylov subspace obtained from the Arnoldi iteration that maps the time-evolution generated directly by the Floquet unitary onto dynamics of a single particle on a fictitious chain with longer range hopping. While the former Krylov subspace is sensitive to the branch of the logarithm of the Floquet unitary, the latter obtained from the Arnoldi scheme is not. The effective single particle models in the Krylov subspace are discussed, and the topological properties of the Krylov chain that ensure stable $0$ and $π$ modes at the boundaries are highlighted. The role of interactions is discussed. Expressions for the lifetime of the almost strong modes are derived in terms of the parameters of the Krylov subspace, and are compared with exact diagonalization.

description: We analyze an advanced two-spring model with an ultra-low effective tip mass to predict nontrivial and physically rich 'fine structure' in the atomic stick-slip motion in Friction Force Microscopy (FFM) experiments. We demonstrate that this fine structure is present in recent, puzzling experiments. This shows that the tip apex can be completely or partially delocalized, thus shedding new light on what is measured in FFM and, possibly, what can happen with the asperities that establish the contact between macroscopic sliding bodies.

description: The Doctoral School of Nova University Lisbon since 2015 offers a course in Research Data Management. This course was designed for doctoral candidates but allows other researchers, researcher managers, librarians, and research support staff from NOVA University to register. The initiative was taken by members of the University libraries, who saw an opportunity in national and European level policy developments to propose the dissemination of good practices on research data management to better address the needs of the academic staff at their institution. This good practice is part of a collection presented in the report "Good Practices in FAIR Competence Education", which aims to provides universities with points of inspiration and practical examples of how fellow institutions and organisations in the higher education sector addressed the need for more RDM and FAIR data-related skills to be taught at the bachelor, master and doctoral levels.

Population synthesis study of the Gaia binary white dwarf population within 100 pc
Creators: name: Torres, S.
Publisher: name: Zenodo
Year: 2019

description: Gaia-DR2 has provided an unprecedented wealth of information about the white dwarf population of our Galaxy. In particular, our estimates show that the sample up to 100 pc from the Sun can be considered as practically complete. This fact permits to obtain accurate statistics about the percentages of the different subpopulations, such as the number of resolved/unresolved double degenerate systems, or white dwarf plus main sequence stars. With the aid of a detailed population synthesis code we are able to fit the best models parameters thus obtaining valuable information about the initial separation distribution, the binary fraction or the initial mass and ratio distribution, among others.

About Bianchi I with time varying constants
Creators: name: Belinchón, José Antonio
Publisher: name: arXiv
Year: 2007
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: In this paper we study how to attack through different techniques a perfect fluid Bianchi I model with variable G, and $Λ.$ These tactics are: Lie groups method (LM), imposing a particular symmetry, self-similarity (SS), matter collineations (MC). and kinematical self-similarity (KSS). We compare both tactics since they are quite similar (symmetry principles). We arrive to the conclusion that the LM is too restrictive and brings us to get only the flat FRW solution with G=const. and $Λ=0$. The SS, MC and KSS approaches bring us to obtain the following solution: G is a decreasing time function and $Λ\thickapprox t^{-2}$, with $Λ<0$, while the exponents of the scale factor must satisfy the conditions $\sum_{i=1}% ^{3}α_{i}=1$ and $\sum_{i=1}^{3}α_{i}^{2}<1,$ $\forallω\in(-1,1)$, relaxing in this way the Kasner conditions.

International cooperation in the Alaska-British Columbia-Yukon Region
Creators: name: Gray, Glenn Thomas
Publisher: name: University of British Columbia
Year: 2010

description: The primary purpose of this thesis is to investigate transboundary cooperation in the Alaska-British Columbia-Yukon Region (ABCY Region). The study focuses on political relations about environmental and natural resource issues. It is argued that there are more appropriate means for cooperative planning in the transborder region than presently employed. Current relations between the three jurisdictions will be evaluated followed by recommendations for improving them. Government cooperation occurs through a complex network of federal, sub-national, regional and local channels. International conflicts in the region have occurred throughout recorded history but means addressing them have changed throughout time. Despite some persistent problems, Alaska-Canadian relations are for the most part amicable. The federal governments have historically had a major presence in Alaska and the Yukon while B.C. manages most of its land. Resource economies of all three jurisdictions follow cycles of booms and busts. Subsistence hunting and fishing and government payments help soften the busts. Access, distances to markets, power shortages, and poor resource markets provide substantial economic dilemmas. International institutions have been developed for a wide spectrum of issues yet few of them are capable of addressing the relationships between resource sectors. Three notable institutions have been used to address multi-sector issues: the Trialteral-Heads-of-Government (THOG) meetings, legislative exchanges, and meetings between Juneau and Whitehorse. Institutions for cooperation are generally Insufficient, they are short-lived, and cooperation occurs on an ad hoc basis. Because most of the region is undeveloped, an excellent opportunity exists to design institutions capable of anticipating and mitigating future environmental and land use problems early on. It is recommended that a proactive, integrated approach involving regional and local interests be instituted. Relations need to be structured enough to encourage regular interaction yet flexible enough to respond to change. The relationship could be strengthened by augmenting existing institutions and creating a few new ones. It is recommended that general guidelines for cooperation be developed. Annual THOG meetings should be supplemented by meetings of a coordinating committee and sectoral subcommittees. Communication between on-the-ground managers should be encouraged. Conflict resolution procedures should also be considered to assure timely response to problems. A major recommendation of this thesis is the creation of international regional conferences. These meetings would provide a foundation for future negotiations about the major issues in each of five sub-regions along the border.
Are Bosonic Replicas Faulty?

description: Motivated by the ongoing discussion about a seeming asymmetry in the performance of fermionic and bosonic replicas, we present an exact, nonperturbative approach to zero-dimensional replica field theories belonging to the broadly interpreted "beta=2" Dyson symmetry class. We then utilise the formalism developed to demonstrate that the bosonic replicas do correctly reproduce the microscopic spectral density in the QCD inspired chiral Gaussian unitary ensemble. This disproves the myth that the bosonic replica field theories are intrinsically faulty.
