description: In this work "full-wave" simulations of integrated inductors are presented and compared with measurements of fabricated CMOS chips. The good agreement between measurements and simulations demonstrates the accuracy of the tool, which is, hence, a cheaper alternative to experimental characterization. Furthermore, the proposed approach may give precious hints for performance improvements, by making internal device fields and currents available for the VLSI designer and providing compact, most effective, equivalent models.

description: The optical properties the high-temperature superconductor La{2-x}Ba{x}CuO{4} have been measured over a wide frequency and temperature range for light polarized in the a-b planes and along the c axis. Three different Ba concentrations have been examined, x=0.095 with a critical temperature T_c=32 K, x=0.125 with T_c ~ 2.4 K, and x=0.145 with T_c ~ 24 K. The in-plane behavior of the optical conductivity for these materials at high temperature is described by a Drude-like response with a scattering rate that decreases with temperature. Below T_c in the x=0.095 and 0.145 materials there is a clear signature of the formation of a SC state in the optical properties allowing the strength of the condensate (ρ_{s0}) and the penetration depth to be determined. In the anomalous 1/8 phase, some spectral weight shifts from lower to higher frequency (above 300 cm^{-1}) on cooling below the spin-ordering temperature T_{so} ~ 42 K, associated with the onset of spin-stripe order; we discuss alternative interpretations in terms of a conventional density-wave gap versus the response to pair-density-wave SC. The disappearance of the low-frequency spectral weight at low temperature may indicate the formation of a 2D SC state below the Berezinskii-Kosterlitz-Thouless transition at about 16 K prior to the onset of bulk 3D SC. The two dopings for which a SC response is observed both fall on the universal scaling line ρ_{s0}/8 ~ 4.4 σ_{dc} T_c. The optical properties for light polarized along the c axis reveal an insulating character dominated by lattice vibrations, superimposed on a weak electronic background. In the x=0.095 and 0.145 materials a Josephson plasma edge is observed in the reflectance below T_c. No Josephson plasma edge is observed in the 1/8 phase, suggesting that the presence of charge and spin order frustrates the formation of a supercurrent and bulk 3D SC.

description: We show that particles can split only when their group velocity exceeds their phase velocity. In this sense the splitting process is the quantum analog of the modulational instability in anomalous dispersive media. In the case of a neutrino whose dispersion relation contains a subdominant Lorentz-violating correction of the form aP^k, the neutrino will decay into two neutrinos and an antineutrino at a rate proportional to a^3G_F^2E^{2+3k}. Unlike the Cohen-Glashow instability, the splitting instability exists even if all particles involved in the interaction have the same dispersion relations at the relevant energy scales. We show that this instability leads to strong constraints even if the energy E is a function of both the momentum P and also of the background density rho, for example we show that it alone would have been sufficient to eliminate any model of the MINOS/OPERA velocity anomaly which modifies the neutrino dispersion relation while leaving those of other particles intact.

Characterizing the immunomodulatory effects of the antioxidant TEMPOL in a model of multiple sclerosis
Creators: name: Neil, Sarah Elizabeth
Publisher: name: University of British Columbia
Year: 2015

description: Background: Reactive oxygen and nitrogen species are implicated in inflammatory-mediated damage to the central nervous system in multiple sclerosis (MS) and an animal model of the disease, experimental autoimmune encephalomyelitis (EAE). We have shown that oral administration of the antioxidant TEMPOL (4-hydroxy-2,2,6,6-tetramethylpiperidine-N-oxyl), a stable nitroxide radical, lowers incidence and reduces severity of disease in EAE. We hypothesize that TEMPOL limits inflammatory demyelinating disease by regulating the development of pathogenic immune responses that influence immune cell activation, including T cell and antigen presenting cell phenotypes and function. Methods: Immune responses were compared between control and TEMPOL-fed EAE or healthy mice by examining differences in proliferation, population distribution, surface marker expression, and cytokine production in immune cells isolated from lymphoid organs. The effect of added TEMPOL on immune cell proliferation and phenotype was also studied in vitro using mixed lymphocyte reactions (MLR) with human or mouse cells, and in isolated murine lymphoid cell cultures stimulated with anti-CD3. Results: TEMPOL-fed animals exhibit comparable levels of myelin-reactive T cells versus controls, but show reduced production of the pro-inflammatory cytokines interferon gamma, tumor necrosis factor alpha, and transforming growth factor-beta 1. Flow cytometry showed enrichment of CD8+ over CD4+ T cells in lymphoid tissues of TEMPOL-fed EAE mice, as well as decreased MHC II and increased CD80 and CD86 expression in myeloid cells and myeloid dendritic cell (DC) populations. Enrichment of Foxp3+ regulatory T cells was also observed in lymph nodes with TEMPOL. In vitro, iii TEMPOL was found to enhance proliferation of lymphoid cells in mouse MLR or when stimulated with anti-CD3 in a dose-dependent manner. Human MLR experiments also showed enhanced cell proliferation and enrichment of CD8 T cells in the presence of TEMPOL. Adding TEMPOL to cell cultures decreased expression of MHC II, CD80, and CD86 in splenic myeloid cells and myeloid DCs. Conclusions: These studies suggest that TEMPOL is not globally immunosuppressive, but instead alters the phenotype of antigen-specific or autoreactive immune cells generated in vivo, reducing the pro-inflammatory nature of immune responses in EAE. These immunomodulatory properties contribute to TEMPOL’s potential as an efficacious therapeutic in MS.

description: Accurate oscillator phase-noise simulation is a key problem in MMIC design, which is not solved satisfactory so far and needs further investigation. In this paper, a Ka-band MMIC oscillator with GaInP/GaAs HBT and on-chip resonator is treated as an example. Measured phase noise reaches -90 dBc/Hz and below at 100 kHz offset. To evaluate phase-noise predic-tion, the circuit is simulated using different commercial simulation tools and HBT models. Con-siderable differences in simulation results are observed.
The flavor symmetry in the standard model and the triality symmetry

description: A Dirac fermion is expressed by a 4 component spinor which is a combination of two quaternions and which can be treated as an octonion. The octonion possesses the triality symmetry, which defines symmetry of fermion spinors and bosonic vector fields. The triality symmetry relates three sets of spinors and two sets of vectors, which are transformed among themselves via transformations $G_{23}, G_{12}, G_{13}$, $G_{123}$ and $G_{132}$. If the electromagnetic (EM) interaction is sensitive to the triality symmetry, i.e. EM probe selects one triality sector, EM signals from the 5 transformed world would not be detected, and be treated as the dark matter. According to an astrophysical measurement, the ratio of the dark to ordinary matter in the universe as a whole is almost exactly 5. We expect quarks are insensitive to the triality, and triality will appear as three times larger flavor degrees of freedom in the lattice simulation.

description: We analyze equilibration times of subsystems of a larger system under a random total Hamiltonian, in which the basis of the Hamiltonian is drawn from the Haar measure. We obtain that the time of equilibration is of the order of the inverse of the arithmetic average of the Bohr frequencies. To compute the average over a random basis, we compute the inverse of a matrix of overlaps of operators which permute four systems. We first obtain results on such a matrix for a representation of an arbitrary finite group and then apply it to the particular representation of the permutation group under consideration.

description: The bandstructure of gold is calculated using many-body perturbation theory (MBPT). Different approximations within the GW approach are considered. Standard single shot G0W0 corrections shift the unoccupied bands up by ~0.2 eV and the first sp-like occupied band down by ~0.4 eV, while leaving unchanged the 5d occupied bands. Beyond G0W0, quasiparticle self-consistency on the wavefunctions lowers the occupied 5d bands by 0.35 eV. Globally, many-body effects achieve an opening of the interband gap (5d-6sp gap) of 0.35 to 0.75 eV approaching the experimental results. Finally, the quasiparticle bandstructure is compared to the one obtained by the widely used HSE (Heyd, Scuseria, and Ernzerhof) hybrid functional.

Investigation of the collagenolytic activity of cathepsin K complexes by site-directed mutagenesis
Creators: name: Takimoto, Shinako
Publisher: name: University of British Columbia
Year: 2013

description: Cathepsin K (catK) is a lysosomal cysteine protease predominantly expressed in osteoclasts. It is the most potent collagenase and elastase in human and involved in a variety of physiological functions including bone degradation, wound healing, maturation of hormones, and a range of important proteolytic activities required for normal cellular function. The main organic constituent of bone, type I collagen, has a highly organized and tightly packed structure and is resistant to proteolysis by most proteases. CatK is the only human protease that efficiently cleaves triple helical collagen, leading to the complete degradation of bone organic matter. This enzyme is the main protease expressed by osteoclasts and is responsible for bone degradation during bone resorption. In recent years, it has been shown that catK forms a complex with bone associated glycosaminoglycans (GAGs) to gain this collagenase activity. However, precise mechanism remains unclear. Due to the major role in bone resorption, catK has been a pharmaceutical target for osteoporosis treatment. Several catK inhibitors have been developed, yet adverse side effects remain a concern. A major issue of the active site inhibitors is its interference to other functions of this enzyme. Gaining the insight of mechanical details of collagenolytic activity of catK can lead to substrate-targeting specific inhibitors that can treat osteoporosis with minimum side effects. There are two catK-GAG complex models based on x-ray crystallography developed in our laboratory; the dimer and the tetramer models. In this study, mutant proteases were made to assess the role of specific protein interaction sites in these proposed models. Mutation at one residue in particular, N99, exhibited 40~50% reduction of degradation activity toward soluble and insoluble collagen without affecting regular proteolytic activity. The atomic force microscopy analysis revealed that the complex formation, observed in the wild type enzyme, was compromised in this mutant protease. This indicates that N99 contributes to the protein interaction necessary for the collagenolytic catK complex formation. Additionally, two mutant proteases showed facilitated collagenase activity against insoluble fibers. These finding contribute to gain better understanding of catK’s collagenolytic activity and will lead development of exosite inhibitors to treat osteoporosis in the future.

description: This paper studies a polymer chain in the vicinity of a linear interface separating two immiscible solvents. The polymer consists of random monomer types, while the interface carries random charges. Both the monomer types and the charges are given by i.i.d. sequences of random variables. The configurations of the polymer are directed paths that can make i.i.d. excursions of finite length above and below the interface. The Hamiltonian has two parts: a monomer-solvent interaction ("copolymer") and a monomer-interface interaction ("pinning"). The quenched and the annealed version of the model each undergo a transition from a localized phase (where the polymer stays close to the interface) to a delocalized phase (where the polymer wanders away from the interface). We exploit the approach developed in [5] and [3] to derive variational formulas for the quenched and the annealed free energy per monomer. These variational formulas are analyzed to obtain detailed information on the critical curves separating the two phases and on the typical behavior of the polymer in each of the two phases. Our main results settle a number of open questions.

description: Future quantum information networks will likely consist of quantum and classical agents, who have the ability to communicate in a variety of ways with trusted and untrusted parties and securely delegate computational tasks to untrusted large-scale quantum computing servers. Multipartite quantum entanglement is a fundamental resource for such a network and hence it is imperative to study the possibility of verifying a multipartite entanglement source in a way that is efficient and provides strong guarantees even in the presence of multiple dishonest parties. In this work, we show how an agent of a quantum network can perform a distributed verification of a multipartite entangled source with minimal resources, which is, nevertheless, resistant against any number of dishonest parties. Moreover, we provide a tight tradeoff between the level of security and the distance between the state produced by the source and the ideal maximally entangled state. Last, by adding the resource of a trusted common random source, we can further provide security guarantees for all honest parties in the quantum network simultaneously.

description: In this paper, we presented a novel structure of microstrip directional coupler for realizing the high directivity characteristic and tight coupling. The achievement of the high directivity with microstrip configuration was carried out by matching the even and odd mode effective phase velocities. By using 2- dimensional finite element(FE) calculations, the phase velocity for each mode and design parameters were extracted for given dimensions. Based on the extracted design parameter with phase matched condition, we designed and fabricated 3dB and 4.7dB directional coupler at 2.0GHz. Experimental results of microstrip coupler show good performance with excellent isolation characteristics.

description: A novel 90-degree waveguide twist is presented. The design features compactness by utilizing a central triple-mode quarter-wave transformer region between input and output waveguides of different cross sections. Return-loss values in excess of 30 dB are obtained over an operating bandwidth close to 20 percent. Larger bandwidths are obtained by using additional quarter-wave steps preceding and/or succeeding the central transformer region. Several different design examples at 4, 6, 19 and 26 GHz are presented for this unique 90- degree twist transformer approach. Experimental verification is provided in the 6 and 19 GHz range.

description: We identify different helicity degrees of freedom of Fierz-Paulian massive gravity around generic backgrounds. We show that the two-parameter family proposed by de Rham, Gabadadze, and Tolley always propagates five degrees of freedom and therefore is free from the Boulware-Deser ghost. The analysis has a number of byproducts, among which (a) it shows how the original decoupling limit construction ensures ghost freedom of the full theory, (b) it reveals an enhanced symmetry of the theory around linearized backgrounds, and (c) it allows us to give an algorithm for finding dispersion relations. The proof naturally extends to generalizations of the theory with a reference metric different from Minkowski.

description: This paper presents a novel application coplanar waveguide (CPW) series stubs. A 1-bit CPW phase shifter for LMCS applications (28 GHz) is designed. Switching between two filters with appropriate phase characteristics allows the introduction of a phase shift in the signal. This low loss and compact novel phase shifter easily accom-modates the required 2 GHz bandwidth of LMCS with insertion losses of less than 0.8 dB. Being more compact than the traditional delay line, it is an attractive alternative o existing approaches, especially if combinged with potential micromachined (MEMS) switches.

description: The fully two-dimensional Peierls barrier map of screw dislocations in BCC iron has been calculated using the first principles method to identify the migration path of a dislocation core. An efficient method to correct the effect of the finite size cell used in the first principles method on the energy of a lattice defect was devised to determine the accurate barrier profile. We find that the migration path is close to a straight line which is confined in a $\{110\}$ plane and the Peierls barrier profile is single-humped. This result clarifies a reason that the existing empirical potentials of BCC iron fail to predict the correct mobility path. A line tension model, incorporating these first principles calculation results, is used to predict the kink activation energy to be 0.73 eV in agreement with experiment.

description: The balanced semiconductor solid-state equations as derived in [1] are efficiently coupled to Yee’s FDTD model for Maxwell’s electromagnetic equations. The resulting algorithm has capabilities of accurate and effective time-domain simulation of both passive and active devices, which can be used in wireless devices. A novel method that correlates the CFL requirements of the electromagnetic and the device simulator is presented and its application further enhances the numerical stability of the new numerical technique even for sub-micron devices. The discretization problems of a fully adaptive implementation are also discussed in detail.
Vitamin D intake and vitamin D status in 5 - 6 year old children in Vancouver
Creators: name: Rasmussen, Betina Feldfoss
Publisher: name: University of British Columbia

description: Vitamin D is important in maintaining bone health and has recently been proposed to have additional roles in the immune system and brain development. The estimated average requirement (EAR) and recommended dietary allowance (RDA) for vitamin D established by the Institute of Medicine (IOM) in 2011 is 10µg/day and 15µg/day, respectively. When this study was initiated, little information was available on whether vitamin D intakes below the recommendations in young children result in biochemical evidence of vitamin insufficiency or deficiency. Therefore the aims in this thesis were; to estimate vitamin D intakes in children, and the contribution of natural and fortified foods, and supplements; to determine the proportion of children consuming vitamin D below and above the intake recommendations; to use biochemical measures of plasma 25(OH)D to determine the proportion of vitamin D sufficient, insufficient and deficient children; and to estimate the importance of vitamin D intake and season to the children’s plasma 25(OH)D. This was a cross-sectional design with 200 children from Vancouver BC, aged 5.75 years. Vitamin D intakes were estimated using a food frequency questionnaire and 24 hr dietary recalls. Plasma 25 (OH)D was determined by HPLC-tandem mass spectrometry. The median vitamin D intake from foods was below the EAR and RDA. The children obtained 85.9% of their dietary vitamin D from supplements and fortified foods and 14.1% from natural food sources. Total median vitamin D intakes in children given or not given supplements was 13.0 (9.0) µg/day and 4.8 (3.7) µg/day, respectively, P< 0.001. Using the FFQ, 51% and 76% of the children did not meet the EAR and RDA for vitamin D, respectively. However, only 4.7% and 19.0% had a plasma 25 (OH)D below 40 nmol/L or 50 nmol/L, respectively. Unexpectedly, only 12.5% of the children who did not meet the EAR during winter months had a plasma 25 (OH)D below 40 nmol/L. The results in this thesis suggest that children depend on supplements and fortified foods to achieve the current vitamin D intake recommendations. However, despite apparent low vitamin D intakes, few children show biochemical evidence of vitamin D insufficiency, even during winter months.

description: Blockcopolymere von Methylmethacrylat mit Butylmethacrylat wurden mittels "lebender" anionischer Polymerisation über einen weiten Zusammensetzungsbereich unter Variation der Architektur und der Gesamtmolmasse synthetisiert. Für die resultierenden Produkte konnte mittels DSC und TEM eine ausgedehnte Mikrophasenseparation nachgewiesen werden. Bei der Untersuchung der mechanischen Eigenschaften wurde ein unerwarteter Festigkeitssynergismus beobachtet. Daneben wird ein chelatisierend wirkendes Additiv vorgestellt, mit dem die definierte Homopolymerisation von 2-Ethylhexylacrylat sowie die Darstellung von Blockcopolymeren mit Methylmethacrylat möglich ist. Dieses Additiv gestattet ebenfalls die Darstellung von PMMA in reinem Toluen bei Temperaturen T>-20 °C mit relativ geringer Molmassenverteilung (D<1.25) und nahezu vollständigem Umsatz.
description: Block copolymers of methyl methacrylate with butyl methacrylate have been synthesized via "living" anionic polymerization technique with a wide variation concerning composition, architecture and molecular weight. DSC and TEM have proven an extended micro phase separation for the resulting products. An unexpected synergism in tensile strength was observed upon investigation of the mechanical properties of the products. Furthermore, a new chelating additive is introduced which enables the well-defined homopolymerization of 2-ethylhexyl acrylate as well as the synthesis of block copolymers with methyl methacrylate. The synthesis of PMMA has been performed in pure toluene at elevated temperature T>-20 °C nearly quantitatively with a relatively narrow molecular weight distribution D<1.25 using the same additive.

description: Any symmetry reduces a second-order differential equation to a first integral: variational symmetries of the action (exemplified by central field dynamics) lead to conservation laws, but symmetries of only the equations of motion (exemplified by scale-invariant hydrostatics) yield first-order {\em non-conservation laws} between invariants. We obtain these non-conservation laws by extending Noether's Theorem to non-variational symmetries and present an innovative variational formulation of spherical adiabatic hydrostatics. For the scale-invariant case, this novel synthesis of group theory, hydrostatics, and astrophysics allows us to recover all the known properties of polytropes and define a {\em core radius}, inside which polytropes of index $n$ share a common core mass density structure, and outside of which their envelopes differ. The Emden solutions (regular solutions of the Lane-Emden equation) are obtained, along with useful approximations. An appendix discusses the $n=3$ polytrope in order to emphasize how the same mechanical structure allows different thermal structures in relativistic degenerate white dwarfs and zero age main sequence stars.

description: We consider extensions of the Dirac equation with mass terms m1+i*gamma5*m2 and i*m_1+gamma*m2. The corresponding Hamiltonians are Hermitian and pseudo-Hermitian ("gamma5 Hermitian"), respectively. The fundamental spinor solutions for all generalized Dirac equations are found in the helicity basis and brought into concise analytic form. We postulate that the time-ordered product of field operators should yield the Feynman propagator (i*epsilon prescription), and we also postulate that the tardyonic as well as tachyonic Dirac equations should have a smooth massless limit. These postulates lead to sum rules that connect the form of the fundamental field anticommutators with the tensor sums of the fundamental plane-wave eigenspinors and the projectors over positive-energy and negative-energy states. In the massless case, the sum rules are fulfilled by two egregiously simple, distinguished functional forms. The first sum rule remains valid in the case of a tardyonic theory and leads to the canonical massive Dirac field. The second sum rule is valid for a tachyonic mass term and leads to a natural suppression of the right-handed helicity states for tachyonic particles, and left-handed helicity states for tachyonic spin-1/2 antiparticles. When applied to neutrinos, the theory contains a free tachyonic mass parameter. Tachyons are known to be repulsed by gravity. We discuss a possible role of a tachyonic neutrino as a contribution to the accelerated expansion of the Universe ("dark energy").

description: Two photons are said to be identical when they are prepared in the same quantum state. Given the latter, there is a unique way to achieve this. Conversely, there are many different manners to prepare two non-identical photons: they may have different frequency, polarization, amplitude, etc. Therefore, photon distinguishability depends upon the specific degree of freedom being varied. By means of a careful analysis of the coincidence probability distribution in a Hong-Ou-Mandel experiment, we can show that photon distinguishability can be actually quantified by the rate of distinguishability of photons, an experimentally measurable parameter that crucially depends on both the photon quantum state and the degree of freedom under control.

description: Optical control of microwave circuits using photodiode junction capacitance variation due to optical illumination has some advantages such as simplicity and wide possibilities in application, high tuning range, accuracy, and speed. We have proposed to call as photovaractor the device which capacitance changes under illumination and which is used for optical control of microwave circuits. The numerical one-dimensional drift-diffusion model of the photovaractor based on the InP/InGaAs/InGaAsP heterostructure which is taking into account influence of the external electric circuit and parasitic elements was used to calculate the junction capacitance change under illumination. The experimental results and theoretical study of the photovaractor in the frequency range up to 3 GHz are presented.
