description: In this paper we analytically propose an alternative approach to achieve better fairness in scheduling mechanisms which could provide better quality of service particularly for real time application. Our proposal oppose the allocation of the bandwidth which adopted by all previous scheduling mechanism. It rather adopt the opposition approach be proposing the notion of Maxmin-charge which fairly distribute the congestion. Furthermore, analytical proposition of novel mechanism named as Just Queueing is been demonstrated.

Sound transmission characteristics of sandwich panels with a truss lattice core
Creators: name: Moosavi Mehr, Ehsan
Publisher: name: University of British Columbia
Year: 2016

description: Sandwich panels are extensively used in constructional, naval and aerospace structures due to their high stiffness and strength-to-weight ratios. In contrast, sound transmission properties of sandwich panels are adversely influenced by their low effective mass. Phase velocity matching of structural waves propagating within the panel and the incident pressure waves from the surrounding fluid medium lead to coincidence effects (often within the audible range) resulting in reduced impedance and high sound transmission. Truss-like lattice cores with porous microarchitecture and \emph{reduced} inter panel connectivity relative to honeycomb cores promise the potential to satisfy the conflicting structural and vibroacoustic response requirements. This study combines Bloch-wave analysis and the Finite Element Method (FEM) to understand wave propagation and hence sound transmission in sandwich panels with a truss lattice core. Three dimensional coupled fluid-structure finite element simulations are conducted to compare the performance of a representative set of lattice core topologies. Potential advantages of sandwich structures with a lattice core over the traditional shear wall panel designs are identified. The significance of partial band gaps is evident in the sound transmission loss characteristics of the panels studied. This work demonstrates that, even without optimization, significant enhancements in STL performance can be achieved in truss lattice core sandwich panels compared to a traditional sandwich panel employing a honeycomb core under constant mass constraint.

description: In electric double layer transistors with SrTiO3 single crystals, we found distinct differences between electrostatic charge accumulation and electrochemical reaction depending on bias voltages. In contrast to the reversible electrostatic process below 3.7 V with a maximum sheet charge carrier density, nS, of 1014 cm-2, the electrochemical process causes persistent conduction even after removal of the gate bias above 3.75 V. nS reached 1015 cm-2 at 5 V, and the electron mobility at 2 K was as large as 104 cm2/Vs. This persistent conduction originates from defect formation within a few micrometers depth of SrTiO3.

description: We present an analysis of the Suzaku observations of the prototype wind-blown bubble NGC 6888 which is based both on use of standard spectral models and on a direct comparison of theoretical models with observations. The X-ray spectra of NGC 6888 are soft and most of the X-rays are in the (0.3 - 1.5 keV) energy range. But, hard X-rays (1.5 - 4.0 keV) are also detected (~10% of the observed flux). The corresponding spectral fits require a relatively cool plasma with kT < 0.5 keV but much hotter plasma with temperature kT > 2.0 keV is needed to match the observed hard X-ray emission. We find no appreciable temperature variations within the hot bubble in NGC 6888. The derived abundances (N, O, Ne) are consistent with those of the optical nebula. This indicates a common origin of the X-ray emitting gas and the outer cold shell: most of the X-ray plasma (having non-uniform spatial distribution: clumps) has flown into the hot bubble from the optical nebula. If the electron thermal conduction is efficient, this can naturally explain the relatively low plasma temperature of most of the X-ray emitting plasma. Alternatively, the hot bubble in NGC 6888 will be adiabatic and the cold clumps are heated up to X-ray temperatures likely by energy exchange between the heavy particles (hot ions diffusing into the cold clumps).

description: We use the technique developed by Becchi and Imbimbo to construct a well-defined BRST-invariant path integral formulation of pure spinor amplitudes. The space of pure spinors can be viewed from the algebraic geometry point of view as a collection of open sets where the constraints can be solved and a free independent set of variables can be defined. On the intersections of those open sets, the functional measure jumps and one has to add boundary terms to construct a well-defined path integral. The result is the definition of the pure spinor integration measure constructed in term of differential forms on each single patch.

description: We study the phase diagram of repulsively interacting spin-1 bosons in optical lattices at unit filling, showing that an externally induced quadratic Zeeman effect may lead to a rich physics characterized by various phases and phase transitions. We find that the main properties of the system may be described by an effective field model, which provides the precise location of the phase boundaries for any dimension, being in excellent agreement with our numerical calculations for one-dimensional systems. Our work provides a quantitative guide for the experimental analysis of various types of field-induced quantum phase transitions in spin-1 lattice bosons. These transitions, which are precluded in spin-1/2 systems, may be realized using an externally modified quadratic Zeeman coupling, similar to recent experiments with spinor condensates in the continuum.

Cytokine and microbial regulators of T cell development, differentiation and function.
Creators: name: Plumb, Adam
Publisher: name: University of British Columbia
Year: 2016

description: The cytokine Interleukin-7 (IL-7) is critical for T cell development and function. Mutations that block IL-7 signaling in humans cause severe combined immunodeficiency syndrome due to the failure of T cells to develop. Conversely, mutations that result in constitutive signaling through the IL-7 receptor can drive human leukemias, including Early Thymic Progenitor (ETP) acute lymphoblast leukemia. How IL-7 influences ETP development is still unclear since ETPs do not normally express IL-7Rα. We found that ETPs are highly dependent on and sensitive to changes in IL-7 signaling however, IL-7Rα expressing bone marrow progenitors are not. IL-7 does not regulate the survival or proliferation of ETPs, although it does at subsequent stages of T cell development. We hypothesize an instructive role of IL-7 signaling in the differentiation or migration of bone marrow precursors of ETPs that is distinct from its classic mechanisms regulating survival and proliferation. Adjuvant IL-7 has been shown to increase the quantity and quality of T cell responses to clear chronic viral infections, however, its physiological role in anti-viral T cells is unclear. We found that IL-7 signaling was required for efficient clearance of Influenza A virus (IAV) and protection from viral induced pathology. T cells require cell intrinsic IL-7 signaling for efficient primary CD4 and CD8 T cell responses to IAV. The requirement for IL-7 signaling in the anti-viral response, and the ability of exogenous IL-7 to boost T cell responses suggests that it may be clinically useful in therapy or vaccination against IAV. IAV remains an important global health challenge, with up to 10% of the global population infected annually. Current IAV vaccines do not generate universal cross-serotype immunity. T cell memory responses to IAV correlate with cross-serotype protection. Transcutaneous immunization has shown potential to induce memory T cell responses that can protect against infections at other mucosal sites, including the lung. We found that transcutaneous immunization generates a strong memory CD8 T cell response that can protect from challenge with IAV. Therefore, transcutaneous immunization may be a useful to produce cross-serotype IAV immunity.

description: Single emitters have been considered as sources of single photons in various contexts such as cryptography, quantum computation, spectroscopy, and metrology. The success of these applications will crucially rely on the efficient directional emission of photons into well-defined modes. To accomplish a high efficiency, researchers have investigated microcavities at cryogenic temperatures, photonic nanowires, and near-field coupling to metallic nano-antennas. However, despite an impressive progress, the existing realizations substantially fall short of unity collection efficiency. Here we report on a theoretical and experimental study of a dielectric planar antenna, which uses a layered structure for tailoring the angular emission of a single oriented molecule. We demonstrate a collection efficiency of 96% using a microscope objective at room temperature and obtain record detection rates of about 50 MHz. Our scheme is wavelength-insensitive and can be readily extended to other solid-state emitters such as color centers and semiconductor quantum dots.

description: Lie systems form a class of systems of first-order ordinary differential equations whose general solutions can be described in terms of certain finite families of particular solutions and a set of constants, by means of a particular type of mapping: the so-called superposition rule. Apart from this fundamental property, Lie systems enjoy many other geometrical features and they appear in multiple branches of Mathematics and Physics, which strongly motivates their study. These facts, together with the authors' recent findings in the theory of Lie systems, led to the redaction of this essay, which aims to describe such new achievements within a self-contained guide to the whole theory of Lie systems, their generalisations, and applications.

description: We propose a spectrum for a class of gauged non-compact G/Ad(H) WZNW models, including spectrally flowed images of highest, lowest, and mixed extremal weight modules. These are combined into blocks whose characters, due to the Lorentzian signature of the target space, are divergent and treated as formal expressions in need of regularisation. Assuming that this is possible, we show that these extended characters transform linearly under modular transformations, and can be used to write down modular invariant partition functions.

description: A re-analysis of the Stokes-parameter spectra obtained of the z=0.692 21 cm absorption line toward 3C 286 shows that our original claimed detection of Zeeman splitting by a line-of-sight magnetic field, B_los = 87 microgauss is incorrect. Because of an insidious software error, what we reported as Stokes V is actually Stokes U: the revised Stokes V spectrum indicates a 3-sigma upper limit of B_los < 17 microgauss. The correct analysis reveals an absorption feature in fractional polarization that is offset in velocity from the Stokes I spectrum by -1.9 km/s. The polarization position-angle spectrum shows a dip that is also significantly offset from the Stokes I feature, but at a velocity that differs slightly from the absorption feature in fractional polarization. We model the absorption feature with 3 velocity components against the core-jet structure of 3C 286. Our chisquare minimization fitting results in components with differing (1) ratios of H I column density to spin temperature, (2) velocity centroids, and (3) velocity dispersions. The change in polarization position angle with frequency implies incomplete coverage of the background jet source by the absorber. It also implies a spatial variation of the polarization position angle across the jet source, which is observed at frequencies higher than the 839.4 MHz absorption frequency. The multi-component structure of the gas is best understood in terms of components with spatial scales of ~100 pc comprised of hundreds of low-temperature (T < 200 K) clouds with linear dimensions of about 1 pc.

description: We consider the focusing (attractive) nonlinear Schrödinger (NLS) equation with an external, symmetric potential which vanishes at infinity and supports a linear bound state. We prove that the symmetric, nonlinear ground states must undergo a symmetry breaking bifurcation if the potential has a non-degenerate local maxima at zero. Under a generic assumption we show that the bifurcation is either subcritical or supercritical pitchfork. In the particular case of double-well potentials with large separation, the power of nonlinearity determines the subcritical or supercritical character of the bifurcation. The results are obtained from a careful analysis of the spectral properties of the ground states at both small and large values for the corresponding eigenvalue parameter. We employ a novel technique combining concentration--compactness and spectral properties of linearized Schrödinger type operators to show that the symmetric ground states can either be uniquely continued for the entire interval of the eigenvalue parameter or they undergo a symmetry--breaking pitchfork bifurcation due to the second eigenvalue of the linearized operator crossing zero. In addition we prove the appropriate scaling for the stationary states in the limit of large values of the eigenvalue parameter. The scaling and our novel technique imply that all ground states at large eigenvalues must be localized near a critical point of the potential and bifurcate from the soliton of the focusing NLS equation without potential localized at the same point. The theoretical results are illustrated numerically for a double-well potential obtained after the splitting of a single-well potential. We compare the cases before and after the splitting, and numerically investigate bifurcation and stability properties of the ground states which are beyond the reach of our theoretical tools.

description: We present a direct measurement of the mass difference between $t$ and $\bar{t}$ quarks using $\ttbar$ candidate events in the lepton+jets channel, collected with the CDF II detector at Fermilab's 1.96 TeV Tevatron \ppbar Collider. We make an event by event estimate of the mass difference to construct templates for top quark pair signal events and background events. The resulting mass difference distribution of data is compared to templates of signals and background using a maximum likelihood fit. From a sample corresponding to an integrated luminosity of \invfb{5.6}, we measure a mass difference, $\dmt = \mathrm{M}_{t} - \mathrm{M}_{\bar{t}} = -3.3 \pm 1.4(stat) \pm 1.0(syst)}$, approximately two standard deviations away from the CPT hypothesis of zero mass difference. This is the most precise measurement of a mass difference between $t$ and its $\bar{t}$ partner to date.

Learning to relate : an exploration of Indigenous Science Education
Creators: name: Baker, Jeff Jordan
Publisher: name: University of British Columbia
Year: 2016

description: This dissertation shares the story of my research exploring the transformative possibilities of Indigenous Science Education for catalyzing the emergence of more equitable and sustainable ways of living. It is an educational response to humanitarian and ecological crises, and draws on the holistic frames of complexity and Indigenous knowledges to balance the dominance of the mechanistic worldview in which these crises are rooted, and that permeates school science. Weaving participatory action research and Indigenous research methodologies into an Indigenous Métissage, my research sought to decolonize and Indigenize school science, eventually focusing on sharing my own story of change and transformation. The research was conducted through four years of participation and relationship building in the local Indigenous education community in my hometown of Saskatoon, Saskatchewan, particularly through ceremony, and employed conversation and anecdotal narrative as primary methods. These experiences led me to suggest miskasowin, a Plains Cree term meaning “to find one’s centre,” as a goal of Indigenous Science Education, which I interpret as a process of “learning to relate,” fostering more relational worldviews and identities that connect us in multiple ways with the dynamic, living, patterns of nature. I describe my process of miskasowin as shaped by complexity and Indigenous knowledges and occurring through a “slow pedagogy of relations” that involved ceremony, story, land, and language, and that fostered a deeper sense of humility and reverence for life.
SPECT/CT quantification of ¹⁷⁷Lu for dosimetry in radionuclide therapy treatments of neuroendocrine tumors
Creators: name: Uribe Muñoz, Carlos Felipe
Publisher: name: University of British Columbia
Year: 2016

description: Peptide receptor radionuclide therapy (PRRT) shows promising results in the treatment of neuroendocrine tumors. These tumors over-express somatostatin receptors that allow us to label somatostatin analogues with ¹⁷⁷Lu to deliver dose to the tumor. However, currently every patient receives the same amount of radioactivity of approximately 7400 MBq per treatment cycle. With this “one dose fits all” approach, differences between patients are not taken into account resulting in some being under-treated while others over-treated. The aim of this thesis was to develop a simple protocol for ¹⁷⁷Lu activity quantification for patients undergoing PRRT with the purpose of performing personalized dose assessments. Physics phenomena that influence image quantification were investigated. As electrons emitted in the decay of ¹⁷⁷Lu result in creation of Bremsstrahlung, Monte-Carlo simulations were performed to investigate this effect on image quantification of ¹⁷⁷Lu. Phantom experiments with different attenuation and scatter conditions were performed to test quantification accuracy and evaluate performance of several segmentation methods. Images were reconstructed using the OSEM algorithm and two scatter correction methods were compared. An experiment to measure the camera deadtime was performed by adding activity into a bottle placed in a cylindrical phantom. Plots for observed count rate vs. true count rate were made, and the deadtime was calculated based on the paralyzable model. The protocol was applied to four patient data, and OLINDA and voxelized dosimetry calculations were used to create dose volume histograms for the kidneys. Lastly, a graphical user interface to allow for the quantitative reconstruction of the data obtained using any of the manufacturers was developed. Our results suggest that Bremsstrahlung contributions to the detected energy spectrum in imaging studies of ¹⁷⁷Lu have no degrading effects in image quantification. Our protocol recovers the activity in kidneys to within 10%. The deadtime correction based on paralyzable model was accurate for the count rates measured. The deadtime corrections should be performed based on scatter corrected photopeak window instead of the full spectrum. Lastly, the dose delivered to the kidneys in patient data was lower than the suggested dose per session in order to reach current toxicity limits.

description: [Abridged] We investigate the use of a wide variety of spectroscopic measurements to determine distances to low-redshift Type Ia supernovae (SN Ia). We consider linear models for predicting distances to SN Ia using light-curve width and color parameters (determined using the SALT2 light-curve fitter) and a spectroscopic indicator, and evaluate the resulting Hubble diagram scatter using a cross-validation procedure. We confirm the ability of spectral flux ratios alone at maximum light to reduce the scatter of Hubble residuals by ~10% with respect to the standard combination of light-curve width and color. When used in combination with the SALT2 color parameter, the color-corrected flux ratio R^c(6420/5290) at maximum light leads to an even lower scatter, although the improvement has low statistical significance (<2 sigma) given the size of our sample (26 SN Ia). We highlight the importance of an accurate relative flux calibration and the failure of this method for highly-reddened objects. Comparison with synthetic spectra from 2D delayed-detonation explosion models shows that the correlation of R(6630/4400) with SN Ia absolute magnitudes can be largely attributed to intrinsic color variations and not to reddening by dust in the host galaxy. We consider flux ratios at other ages, as well as the use of pairs of flux ratios, revealing the presence of small-scale intrinsic spectroscopic variations in the iron-group dominated absorption features around ~4300 A and ~4800 A. The best flux ratio overall is the color-corrected R^c(4610/4260) at t=-2.5d from maximum light, which leads to ~30% lower scatter with respect to the standard combination of light-curve width and color. We examine other spectroscopic indicators related to line-profile morphology, but none appear to lead to a significant improvement over the standard light-curve width and color parameters.

description: In this paper, we mainly introduce the notion of an open uniform (G) at non-isolated points, and show that a space $X$ has an open uniform (G) at non-isolated points if and only if $X$ is the open boundary-compact image of metric spaces. Moreover, we also discuss the inverse image of spaces with an open uniform (G) at non-isolated points. Two questions about open uniform (G) at non-isolated points are posed.

description: Two different measures of operator entanglement of two-qubit gates, namely, Schmidt strength and linear entropy, are studied. While these measures are shown to have one-to-one relation between them for Schmidt number 2 class of gates, no such relation exists for Schmidt number 4 class, implying that the measures are inequivalent in general. Further, we establish a simple relation between linear entropy and local invariants of two-qubit gates. The implication of the relation is discussed.

Zeroing in on jet quenching: a PHENIX perspective
Creators: name: Jia, Jiangyong
Publisher: name: arXiv
Year: 2010
Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: We review recent progresses on jet quenching measurements by PHENIX. With increased statistics, PHENIX has gone beyond the single hadron suppression $R_{\rm AA}$, and made measurements on multiple jet quenching observables, such as $v_2$, $I_{\rm AA}$ and $v_2^{I_{\rm AA}}$. We argue that, by combining these observables together, one can achieve a better understanding of the energy loss mechanism. We present new $γ$-hadron correlation results with associated hadrons extended to low $p_T$; an enhancement has been observed, suggesting a contribution of genuine medium response that is relatively unbiased by the initial geometry fluctuations. The status of full jet reconstruction and future perspective of PHENIX jet quenching program are discussed.

Performance of strand-based wood composite post-and-beam shear wall system
Creators: name: Lim, Hyungsuk
Publisher: name: University of British Columbia
Year: 2017

description: This dissertation proposes a strand-based wood composite product to be utilized as the vertical members of post-and-beam (P&B) shear walls. Since the shear wall performance is largely governed by connection systems holding the wall components together, the research focuses on the structural behaviour of two key connection types: nail and hold-down connections. The experimental studies were designed to evaluate the effects of orthogonal properties, such as vertical density profile of the strand-based product, on the connection performance. Static load tests were conducted following ASTM standards and Japanese HOWTEC connection performance guidelines. The test results showed that the connections with fasteners mounted on the face-side of the composite product outperform the ones with fasteners mounted on the product’s edge-side. Subsequently, full-scale shear wall tests were conducted on three P&B wall types to study the effect of the fastener driving direction on the wall performance. The test results confirmed that the shear walls with face-driven nails outperforms the ones with edge-driven nails in terms of load carrying capacity. A detailed mechanics-based finite-element connection model RHYST was also developed to predict the load-displacement relationship of a nail connection. It was developed based on an existing connection model HYST which idealizes a dowel-type connector driven into a wood medium as an elasto-plastic beam embedded in a nonlinear foundation that only acts in compression. RHYST assumes that the lateral response of the wood medium does not decrease at any compressive displacement. The presented model takes into account the contribution of the fastener’s vertical displacements on the response of the foundation. The simulation results of RHYST agreed well with the reversed-cyclic nail connection test results in terms of load carrying capacity and energy dissipation. The model is also able to simulate strength and stiffness degradation between the repeated loading cycles. Moreover, the applicability of RHYST was confirmed by incorporating it as a subroutine in a finite-element shear wall model WALL2D. The simulation results of WALL2D with RHYST showed a good agreement with the wall test results.

description: In many-body theory it is often useful to renormalize short-distance, high-momentum components of an interaction via unitary transformations. Such transformations preserve the on-shell physical observables of the two-body system (mostly phase-shifts, hence unitarily-connected effective interactions are often called phase-equivalent), while modifying off-shell T-matrix elements influential in many-body systems. In this paper I lay out a general and systematic approach for controlling the off-shell behavior of an effective interaction, which can be adjusted to many-body properties, and present an application to trapped fermions at the unitary

F-signature exists

description: Suppose R is a Noetherian local ring with prime characteristic p>0. In this article, we show the existence of a local numerical invariant, called the F-signature, which roughly characterizes the asymptotic growth of the number of splittings of the iterates of the Frobenius endomorphism of R. This invariant was first formally defined by C. Huneke and G. Leuschke and has previously been shown to exist only in special cases. The proof of our main result is based on the development of certain uniform Hilbert-Kunz estimates of independent interest. Additionally, we analyze the behavior of the F-signature under finite ring extensions and recover explicit formulae for the F-signatures of finite quotient singularities.

The DEVBOX development education platform : an environment for introducing Verilog to young students
Creators: name: Lee, Keith
Publisher: name: University of British Columbia
Year: 2016

description: Hardware description languages are considered to be challenging to learn, as are the logic design concepts required to effectively use them. University logic design courses are considered by many to be much more difficult than their software development counterparts and the subject is not generally addressed by pre-university curricula. Introducing hardware description earlier in a student’s career will improve their chances of success in future logic design courses. The barrier-to-entry faced in introducing hardware description, caused by complex development environments and the learning of fundamental logic design concepts, must be overcome in order to facilitate a self-directed and interactive educational environment for young students. DEVBOX, an embedded System-on-Chip programming education platform, simplifies the learning process with its bare-bones development tools and interactive instructional material. It has been designed to be a self-contained, installation-free educational device with a browser-based interface that is self explanatory and easy to use. By including Verilog, a popular hardware description language, alongside the software programming languages in its repertoire, DEVBOX caters to the needs of introductory and intermediate logic design students in a dynamic self-directed learning environment.
