description: It has been shown that the orbits of motion for a wide class of nonrelativistic Hamiltonian systems can be described as geodesic flows on a manifold and an associated dual. This method can be applied to a four dimensional manifold of orbits in spacetime associated with a relativistic system. We show that a relativistic Hamiltonian which generates Einstein geodesics, with the addition of a world scalar field, can be put into correspondence with another Hamiltonian with conformally modified metric. Such a construction could account for part of the requirements of Bekenstein for achieving the MOND theory of Milgrom in the post-Newtonian limit. The constraints on the MOND theory imposed by the galactic rotation curves, through this correspondence, would then imply constraints on the structure of the world scalar field. We then use the fact that a Hamiltonian with vector gauge fields results, through such a conformal map, in a Kaluza-Klein type theory, and indicate how the TeVeS structure of Bekenstein and Sanders can be put into this framework. We exhibit a class of infinitesimal gauge transformations on the gauge fields ${\cal U}_μ$ which preserve the Bekenstein-Sanders condition ${\cal U}_μ{\cal U}^μ= -1$. The underlying quantum structure giving rise to these gauge fields is a Hilbert bundle, and the gauge transformations induce a non-commutative behavior to the fields, i.e., they become of Yang-Mills type. Working in the infinitesimal gauge neighborhood of the initial Abelian theory, we show that in the Abelian limit the Yang-Mills field equations provide nonlinear terms which may avoid the caustic singularity found by Contaldi, et al.

description: Background: Disturbed sleep can cause to m health problems such as cognitive impairment, depressed mood, and negative effects on cardiovascular, endocrine, and immune function. This study formulates and optimizes Eszopiclone trilaminate fast dissolving film.Methods: Prepared Eszopiclone trilaminate fast dissolving film (Eszopiclone TFDF) was characterized by disintegration time, drug release, tensile strength (TS), percentage elongation (EB%), folding endurance, taste masking test, and in vitrodissolution test. The selected formulas were F2 (0.5% xanthan gum, 10% propylene glycol), F4 (3% sodium alginate, 10% propylene glycol) and F6 (1.5% pullulan, 10% propylene glycol) were subjected to in vivo study compared to conventional Lunesta® tablet.Results: The results indicated that disintegration time was in the range of 940 m. Drug release was found to be in the field of 78.51%–99.99%, while TS values and EB% differed from 11.12 to 25.74 (MPa) and 25.38%–36.43%, respectively. The folding endurance went between 200 and 300 times. All formulas exhibited acceptable uniformity content, surface pH, film thickness, and a good taste feeling. Conclusion: F4 had the highest Cmax (39.741 ± 6.785-μg/l) and lower Tmax (1.063 hr) among other formulas and conventional tablets. Therefore, FDFs’ technology could increase the therapeutic effect of Eszopiclone.

The manipulation of architectural data
Creators: name: Desbiens, Arthur Roger
Publisher: name: University of British Columbia
Year: 2010

description: This thesis presents a way to manipulate architectural data to achieve alternate schematic design proposals. The process is demonstrated within an extended housing context. In the spirit of the systematic approach, a language and computing steps have been detailed allowing a procedure for the construction of alternate programme strategies. A part of this procedure is devoted to evaluating the performance of each alternative with respect to others. From a triple data hierarchy based on activity types, room types, and attribute requirements, a set of Functional Units is created and constitutes the Architectural Programme. In this programme each Functional Unit has 5 Project Constituents: l) it is place in Sequence, 2) it takes place in a specific Volume, 3) it has a Reference Point and 4) a Direction on the site, 5) it has a Cost. The operations performed to determine those Project Constituents are essentially mathematical computations. However before doing so, a Site Planning Strategy has to be defined regarding the site information likely to influence the Project Constituents. Having established the first schematic design plan, a series of appropriate variations can be developed and evaluated in order to indicated the most appropriated proposal. This thesis does not present the final computer programme to be applied to this system but instead formulates it to be used manually before further investigation. An existing computer program called "INFO", available at the U.B.C. Computing Center, has been mentioned as the potential main support for the data manipulation and maintenance.

description: Supplementary materials: Comparison of Three-Winding Transformer Model Extraction Using FEMM and COMSOL Multiphysics®.This research focuses on simulating a transformer using electromagnetic field solver software: FEMM and COMSOL Multiphysics®. These tools are used to simulate and extract the model of a three-winding transformer. The primary objective of the extracted model is to predict key magnetic parameters, such as leakage and magnetizing inductances. These inductances play a critical role in switch-mode power converter topologies, ensuring proper operation and achieving high efficiency through zero-voltage or zero-current switching. In this study, the transformer, based on an ER28/14/11 core, is simulated using both FEMM and COMSOL, with the resulting models compared to each other and experimental measurements. FEMM is a free, 2D solver, while COMSOL is a commercial, 3D solver. This research aims to evaluate the feasibility of using the non-commercial FEMM tool to simulate complex transformer core shapes. Transformations of the E, ER, and ETD core types for simulation in both 2D axis-symmetric and planar problem types are also proposed.

Teorie e immagini del governo "misto" nel Cinquecento: i casi di Gasparo Contarini, Donato Giannotti, Paolo Paruta e Traiano Boccalini

Publisher: name: Alma Mater Studiorum - Università di Bologna

Subjects: M-FIL/06 Storia della filosofia

description: This doctoral dissertation faces the debated topic of the traditions of Republicanism in the Modern Age assuming, as a point of view, the problem of the "mixed" government.

  The research therefore dwells upon the use of this model in Sixteenth-Century Italy, also in connection with the historical events of two standard Republics such as Florence and Venice.

  The work focuses on Donato Giannotti (1492-1573), Gasparo Contarini (1483-1542) and Paolo Paruta (1540-1598), as the main figures in order to reconstruct the debate on "mixed" constitution: in them, decisive in the attention paid to the peculiar structure of the Venetian Republic, the only of a certain dimension and power to survive after 1530.

  The research takes into account also the writings of Traiano Boccalini (1556-1613): he himself, though being involved in the same topics of debate, sets for some aspects his considerations in the framework of a new theme, that of Reason of State.
The large tower of Babel by Peter Bruegel : its precedents and antecedents in the artistic imagination and in archaeology
Creators: name: Fawcett, Thomas Derek
Publisher: name: University of British Columbia
Year: 2010

description: This thesis was originally commenced with the intention of examining the various artistic representations of the Tower of Babel, then comparing them with possible sources of inspiration such as the Biblical account, Herodotus, and the original (as now revealed by archaeology). So far about two hundred and thirty illustrations have been found, mainly in the form of manuscript illuminations, frescoes, mosaics and paintings. As this piece of research would run into several large volumes, it has been decided to concentrate upon a most outstanding example, that of the painting executed in 1563 by Peter Bruegel which is usually referred to as his "Large Tower of Babel". The precedents and antecedents of this painting have been studied and special attention given to influences such as the medieval traditions of allegory in literature and symbolism in painting. Because of the use of symbolism by Bruegel in much of his painting, an attempt has been made to ascertain whether or not the religious or political motives often connected with this are present-and the conclusion reached is that to some extent they must be. There is at present very little in the way of detailed description of the painting by art historians, and so attention has been given to this, accompanied by a search for sources of Bruegel's inspiration. One result of this has been the discovery that Qiulio Clovio provided some ideas for the painting and himself collected another larger example not now in existence. The description by Vasari would suggest that the subject was something of a wonder in Rome in the 1550s, thus providing another cogent reason for Peter Bruegel's interest in it during and after the time of his visit to Italy. It is concluded that the particular form which Bruegel's tower takes is mainly the cumulative result of his own powerful imagination, the ini alginations of his contemporaries and predecessors, combined with literary detail available from Herodotus and to some extent the Biblical account. While travellers' tales of Middle Eastern towers such as Samarra abounded, it seems unlikely that much of the original tower at Babylon remained to be observed, even if it were recognized in Bruegel's time. With the influence of the archaeological facts available to us today at nil then, comparatively speaking, the thesis section of detailed research into the actual form of the original tower becomes only of interest for the sake of comparison with the artistic form - and as a corroboration of Herodotus' important account. It therefore very properly becomes an appendix.

description: Dark matter could be a composite state of a confining sector with an approximate scale symmetry. We consider the case where the associated pseudo-Goldstone boson, the dilaton, mediates its interactions with the Standard Model. When the confining phase transition in the early universe is supercooled, its dynamics allows for dark matter masses up to $10^6$ TeV. We derive the precise parameter space compatible with all experimental constraints, finding that this scenario can be tested partly by telescopes and entirely by gravitational waves.

description: We study the impact of the full ${\cal O}(α_{s})$ QCD and ${\cal O}(α_{ew})$ electroweak (EW) radiative corrections to the $e^+e^- \to t \bar t Z^0$ process in the standard model (SM), and investigate the dependence of the lowest-order(LO), one-loop QCD and EW corrected cross sections on colliding energy $\sqrt{s}$. The LO, QCD and EW corrected spectrums of the invariant mass of $t\bar t$-pair and the distributions of the transverse momenta of final top-quark and $Z^0$-boson are presented. The numerical results show that the one-loop QCD correction enhances the LO cross section, but the EW one-loop correction generally suppresses the LO cross section with our chosen parameters. In the case of $m_H=120 GeV$, the QCD relative corrections can reach 43.16% when $\sqrt{s} = 500 GeV$, while the EW relative corrections have the values of -9.24%, -4.36% and -5.81%, when $\sqrt{s} = 500 GeV$, $800 GeV$, 1.2 TeV$, respectively.

description: Using Coherent-State (CS) techniques, we prove a sampling theorem for holomorphic functions on the hyperboloid (or its stereographic projection onto the open unit disk $\mathbb D_1$), seen as a homogeneous space of the pseudo-unitary group SU(1,1). We provide a reconstruction formula for bandlimited functions, through a sinc-type kernel, and a discrete Fourier transform from $N$ samples properly chosen. We also study the case of undersampling of band-unlimited functions and the conditions under which a partial reconstruction from $N$ samples is still possible and the accuracy of the approximation, which tends to be exact in the limit $N\to\infty$.

description: We investigate the positivity of double parton distributions with a non-trivial dependence onthe parton colour. It turns out that positivity is not preserved by leading-order evolution from lower to higher scales, in contrast to the case in which parton colour is summed over. We also study the positivity properties of the distributions at small distance between the two partons, where they can be computed in terms of perturbative splitting kernels and ordinary parton densities.

description: We study the angle-resolved spontaneous emission of near-infrared light sources in 3D photonic crystals over a wavelength range from 1200 to 1550 nm. To this end PbSe quantum dots are used as light sources inside titania inverse opal photonic crystals. Strong deviations from the Lambertian emission profile are observed. An attenuation of 60 % is observed in the angle dependent radiant flux emitted from the samples due to photonic stop bands. At angles that correspond to the edges of the stop band the emitted flux is increased by up to 34 %. This increase is explained by the redistribution of Bragg-diffracted light over the available escape angles. The results are quantitatively explained by an expanded escape-function model. This model is based on diffusion theory and adapted to photonic crystals using band structure calculations. Our results are the first angular redistributions and escape functions measured at near-infrared, including telecom, wavelengths. In addition, this is the first time for this model to be applied to describe emission from samples that are optically thick for the excitation light and relatively thin for the photoluminesence light.

description: Auditing plays a pivotal role in the development of trustworthy AI. However, current research primarily focuses on creating auditable AI documentation, which is intended for regulators and experts rather than end-users affected by AI decisions. How to communicate to members of the public that an AI has been audited and considered trustworthy remains an open challenge. This study empirically investigated certification labels as a promising solution. Through interviews (N = 12) and a census-representative survey (N = 302), we investigated end-users' attitudes toward certification labels and their effectiveness in communicating trustworthiness in low- and high-stakes AI scenarios. Based on the survey results, we demonstrate that labels can significantly increase end-users' trust and willingness to use AI in both low- and high-stakes scenarios. However, end-users' preferences for certification labels and their effect on trust and willingness to use AI were more pronounced in high-stake scenarios. Qualitative content analysis of the interviews revealed opportunities and limitations of certification labels, as well as facilitators and inhibitors for the effective use of labels in the context of AI. For example, while certification labels can mitigate data-related concerns expressed by end-users (e.g., privacy and data protection), other concerns (e.g., model performance) are more challenging to address. Our study provides valuable insights and recommendations for designing and implementing certification labels as a promising constituent within the trustworthy AI ecosystem.

description: We conduct a comprehensive analysis of the relationship between central galaxies and their host dark matter halos, as characterized by the stellar mass-halo mass (SM-HM) relation, with rigorous consideration of uncertainties. Our analysis focuses on results from the abundance matching technique, which assumes that every dark matter halo or subhalo above a specific mass threshold hosts one galaxy. We discuss the quantitative effects of uncertainties in observed galaxy stellar mass functions (GSMFs) (including stellar mass estimates and counting uncertainties), halo mass functions (including cosmology and uncertainties from substructure), and the abundance matching technique used to link galaxies to halos (including scatter in this connection). Our analysis results in a robust estimate of the SM-HM relation and its evolution from z=0 to z=4. The shape and evolution are well constrained for z < 1. The largest uncertainties at these redshifts are due to stellar mass estimates; however, failure to account for scatter in stellar masses at fixed halo mass can lead to errors of similar magnitude in the SM-HM relation for central galaxies in massive halos. We also investigate the SM-HM relation to z=4, although the shape of the relation at higher redshifts remains fairly unconstrained when uncertainties are taken into account. These results will provide a powerful tool to inform galaxy evolution models. [Abridged]

Strong NP-Hardness of the Quantum Separability Problem

Publisher: name: arXiv
Year: 2008
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Given the density matrix rho of a bipartite quantum state, the quantum separability problem asks whether rho is entangled or separable. In 2003, Gurvits showed that this problem is NP-hard if rho is located within an inverse exponential (with respect to dimension) distance from the border of the set of separable quantum states. In this paper, we extend this NP-hardness to an inverse polynomial distance from the separable set. The result follows from a simple combination of works by Gurvits, Ioannou, and Liu. We apply our result to show (1) an immediate lower bound on the maximum distance between a bound entangled state and the separable set (assuming P != NP), and (2) NP-hardness for the problem of determining whether a completely positive trace-preserving linear map is entanglement-breaking.

Includes additional details in proof of NP-hardness of determining whether a quantum channel is entanglement-breaking, as well as minor updates to improve readability throughout.

Developers’ guide to profitable housing
Creators: name: Vaughn, Thomas Mack
Publisher: name: University of British Columbia
Year: 2010

description: The central argument of this guide is that there are design features, details, processes, and decisions in housing development which can help the developers' return on his investment. The guidelines have 3 purposes: 1. to improve the developer's awareness of the major problems in housing development; 2. to lessen the risks of front end costs (professional fees, landholding costs, interest on borrowed capital, etc. before project approval and up to final sales) as governmental agencies overseeing development proliferate and public resistance becomes sophisticated; 3. to demonstrate that design (sophistication, elegance, expertise) does not necessarily cut into the developer's profit but can increase that profit and reduce the risks associated with it. Three ways in which design features may relate to development profit are examined in the guidelines. 1) Cost Reduction: imaginative and careful design can reduce the materials required, lessen the amount of energy consumed, optimize on free or existing resources, and improve the efficiency of construction. 2) Delay Prevention: complete design proposals will avoid errors and omissions on the plans, provide early coordination among the design team, utility and servicing companies and the levels of government involved, and address the concerns of the public and governmental planners to lessen resistance to project approval. 3) Marketability: the manner in which features of the site are dealt with and used in the development, and the inclusion of certain design features have strong market appeal which give the developer a competitive 'edge with sales or leasing. The guide is broken into four chapters, each a main area of concern in housing development: the site; the infrastructure; the open space system; and the dwelling unit. In each chapter there are nine to twelve sections; the section is a design feature, item or process. Each section introduces the design feature, lists points of concern, aspects to be considered, and may have some recommendations to be followed. The ways this feature can help profit are listed according to Cost Reduction, Delay Prevention, and Marketability. Lastly, each section may contain examples cases in point, and refer the reader to other illustrations.
Gaudin Models and Multipoint Conformal Blocks II: Comb channel vertices in 3D and 4D

description: It was recently shown that multi-point conformal blocks in higher dimensional conformal field theory can be considered as joint eigenfunctions for a system of commuting differential operators. The latter arise as Hamiltonians of a Gaudin integrable system. In this work we address the reduced fourth order differential operators that measure the choice of 3-point tensor structures for all vertices of 3- and 4-dimensional comb channel conformal blocks. These vertices come associated with a single cross ratio. Remarkably, we identify the vertex operators as Hamiltonians of a crystallographic elliptic Calogero-Moser-Sutherland model that was discovered originally by Etingof, Felder, Ma and Veselov. Our construction is based on a further development of the embedding space formalism for mixed-symmetry tensor fields. The results thereby also apply to comb channel vertices of 5- and 6-point functions in arbitrary dimension.
The elastic electron-deuteron scattering beyond one-photon exchange

description: We discuss the elastic ed scattering beyond Born approximation. It is shown that the reaction amplitude contains six generalized form factors, but only three linearly independent combinations of them (we call them generalized charge, quadrupole and magnetic form factors) contribute to the reaction cross section in the second order perturbation theory. We examine two-photon exchange and find that it includes two types of diagrams, when two virtual photons interact with the same nucleon and when the photons interact with different nucleons. Estimations based on nonrelativistic calculations with the deuteron wave function for realistic NN potential show that the main contribution to the generalized charge, quadrupole and magnetic form factors comes from diagrams of the first type.

description: We demonstrate the agreement between the Higgs branches of two N=2 theories proposed by Argyres and Seiberg to be S-dual, namely the SU(3) gauge theory with six quarks, and the SU(2) gauge theory with one pair of quarks coupled to the superconformal theory with E_6 flavor symmetry. In mathematical terms, we demonstrate the equivalence between a hyperkaehler quotient of a linear space and another hyperkaehler quotient involving the minimal nilpotent orbit of E_6, modulo the identification of the twistor lines.

description: In engineering, physics and chemistry, the study of transport phenomena concerns the exchange of mass, energy, charge, momentum and angular momentum between observed and studied systems. While it draws from fields as diverse as continuum mechanics and thermodynamics, it places a heavy emphasis on the commonalities between the topics covered. Mass, momentum, and heat transport all share a very similar mathematical framework, and the parallels between them are exploited in the study of transport phenomena to draw deep mathematical connections that often provide very useful tools in the analysis of one field that are directly derived from the others. The fundamental analysis in all three subfields of mass, heat, and momentum transfer are often grounded in the simple principle that the total sum of the quantities being studied must be conserved by the system and its environment. Thus, the different phenomena that lead to transport are each considered individually with the knowledge that the sum of their contributions must equal zero. This principle is useful for calculating many relevant quantities. For example, in fluid mechanics, a common use of transport analysis is to determine the velocity profile of a fluid flowing through a rigid volume. Transport phenomena are ubiquitous throughout the engineering disciplines. Some of the most common examples of transport analysis in engineering are seen in the fields of process, chemical, and mechanical engineering, but the subject is a fundamental component of the curriculum in all disciplines involved in any way with fluid mechanics, heat transfer, and mass transfer. It is now considered to be a part of the engineering discipline as much as thermodynamics, mechanics, and electromagnetism.
