The effect of expression of estrus at artificial insemination on target genes in the endometrium, conceptus and corpus luteum of beef cows
Creators: name: Davoodi, Saeideh
Publisher: name: University of British Columbia
Year: 2015

description: The aim of this study was to test the effect of expression of estrus at artificial insemination (AI) on the endometrium, conceptus and corpus luteum (CL) gene expression. Twenty-three multiparous non-lactating Nelore cows were enrolled on an estradiol (E2) and progesterone (P4) based timed-AI protocol (AI = d 0), then slaughtered for endometrium, CL and conceptus collection on d 19. Body condition score (BCS), blood samples and ultrasound examination was performed on d 0, 7 and 18 of the experiment followed by RNA extraction and quantitative reverse transcription polymerase chain reaction (qRT-PCR) analysis of 58 target genes. Data was checked for normality and analysed by ANOVA for repeated measures using proc GLM, MIXED and UNIVARIATE. Estrous expression had no correlation with parameters such as BCS, pre-ovulatory follicle and CL diameter, P4 concentration in plasma on d 7 and 18 after AI and IFN-tau concentration in the uterine flushing (P > 0.05); however, a significant increase was observed in conceptus size (P = 0.02; 38.3 ± 2.8 vs 28.2 ± 2.9). The majority of transcripts affected by estrous expression in the endometrium belong to the immune system and adhesion molecule family (MX1, MX2, MYL12A, MMP19, CXCL10, IGLL1 and SLPI) (P ≤ 0.05). Genes related to apoptosis, P4 synthesis and prostaglandin receptor were down-regulated (CYP11A, BAX and PGF2α receptor) (P < 0.05) in the CL tissue of cows in estrus. In addition, four genes were identified as differentially expressed in the 19 old conceptus from cows observed in estrous (ISG15, PLAU, BMP15 and EEF1A1; P<0.05). There was also a significant effect of P4/d7 mainly affecting immune system, adhesion molecules and wnt signaling pathway of endometrium (IGLL1, MX2, SLPI, TRD, APC, WNT2, GLYCAM1 and MYL12A) (P<0.05). A significant interaction between estrus expression and P4 concentration on d 7 was more pronounced in immune system genes (MX1, MX2, TRD, SLPI and IGLL1; P<0.05). This study demonstrated that estrous expression at the time of AI, in spite of ovulation being induced by E2, could alter the gene expression profile in reproductive tissues during the pre-implantation phase.

description: We study the potential of the current Large Hadron Collider (LHC) 7 TeV run to search for heavy, colored vector-like fermions, which are assumed to carry a conserved Z2 quantum number forcing them to be pair-produced. Each fermion is assumed to decay directly into a Standard Model quark and an invisible stable particle. T-odd quarks (T-quarks) and the lightest T-odd particle (LTP) of the Littlest Higgs model with T-parity provide an example of this setup. We estimate the bounds based on the published CMS search for events with jets and missing transverse energy in the 35 pb-1 data set collected in the 2010 run. We find that T-quark masses below about 450 GeV are ruled out for the LTP mass about 100 GeV. This bound is somewhat stronger than the published Tevatron constraint. We also estimate the reach with higher integrated luminosities expected in the 2011-12 run. If no deviation from the SM is observed, we expect that a bound on the T-quark mass of about 650 GeV, for the LTP mass of 300 GeV and below, can be achieved with 1 fb-1 of data. We comment on the possibility of using initial-state radiation jets to constrain the region with nearly-degenerate T-quark and LTP.

description: We can estimate the size of the speakers based on their speech sounds alone. We had proposed an auditory computational theory of the Stabilised Wavelet-Mellin Transform (SWMT), which segregates information about the size and shape of the vocal tract and glottal vibration, to explain this observation. It has been shown that the auditory representation or excitation pattern (EP) associated with a weighting function based on the SWMT, termed the ``SSI weight,'' can account for the psychometric functions of size perception. In this study, we investigated whether EP with SSI weight can accurately estimate vocal tract lengths (VTLs) which were measured by magnetic resonance imaging (MRI) in male and female subjects. It was found that the use of SSI weight significantly improved the VTL estimation. Furthermore, the estimation errors in the EP with the SSI weight were significantly smaller than those in the commonly used spectra derived from the Fourier transform, Mel filterbank, and WORLD vocoder. It was also shown that the SSI weight can be easily introduced into these spectra to improve the performance.

description: New physics that exhibits irregular tracks such as kinks, intermittent hits or decay in flight may easily be missed at hadron colliders. We demonstrate this by studying viable models of light, O(10 GeV), colored particles that decay predominantly inside the tracker. Such particles can be produced at staggering rates, and yet may not be identified or even triggered on at the LHC, unless specifically searched for. In addition, the models we study provide an explanation for the original measurement of the anomalous charged track distribution by CDF. The presence of irregular tracks in these models reconcile that measurement with the subsequent reanalysis and the null results of ATLAS and CMS. Our study clearly illustrates the need for a comprehensive study of irregular tracks at the LHC.

A systematic analysis of the 'Reading the Mind in the Eyes' task in children and what it means for understanding social perspective taking
Creators: name: Cassels, Tracy Gardiner Caseels
Publisher: name: University of British Columbia
Year: 2015

description: How well we understand social perspective taking is intricately linked to how well we assess this ability; however, there are factors that can influence its assessment, altering how we conceptualize social perspective taking and its development. The goal of the current dissertation was to systematically analyze one of the most popular measures of social perspective taking in children, the Reading the Mind in the Eyes task, by examining three specific measurement issues—what is being measured, response format, and coding scheme—to determine how these issues impact our understanding of social perspective taking more generally. Methods: Three studies were conducted with 249 children aged 4 to 13, including 54 children at-risk for affective perspective taking deficits. Two response formats (forced-choice vs. open-ended) and two coding schemes (term specific vs. valenced) were systematically compared on performance, relations to other abilities, and efficacy at measuring cognitive versus affective perspective taking. Comparison measures included dispositional empathy, cognitive perspective taking, and verbal ability. Results: There was a significant effect of response format, with the forced-choice format related to both cognitive and verbal abilities, suggesting that its performance is more apt to be influenced, unnecessarily, by the participants’ vocabulary knowledge or use of alternate strategies. Furthermore, the forced-choice format was unrelated to dispositional empathy and cognitive perspective taking and failed to differentiate typically-developing from at-risk children. In contrast, the open-ended format was significantly related to dispositional empathy and differentiated at-risk from typically-developing children. Taken together these results a) raise concerns about the use of the Reading the Mind in the Eyes task as a measure of cognitive perspective taking and b) reveal that an open-ended format provides a better measure of affective perspective taking than the forced-choice format. The effect of coding scheme was less clear, with evidence that term-specific coding was linked to vocabulary knowledge only in typically-developing children and only in a forced-choice response format. Implications: Findings are discussed in terms of implications on the type of information that can be gleaned from the Reading the Mind in the Eyes task and their relevance for studying social perspective taking more generally.

Quantum algorithm for the Boolean hidden shift problem

description: The hidden shift problem is a natural place to look for new separations between classical and quantum models of computation. One advantage of this problem is its flexibility, since it can be defined for a whole range of functions and a whole range of underlying groups. In a way, this distinguishes it from the hidden subgroup problem where more stringent requirements about the existence of a periodic subgroup have to be made. And yet, the hidden shift problem proves to be rich enough to capture interesting features of problems of algebraic, geometric, and combinatorial flavor. We present a quantum algorithm to identify the hidden shift for any Boolean function. Using Fourier analysis for Boolean functions we relate the time and query complexity of the algorithm to an intrinsic property of the function, namely its minimum influence. We show that for randomly chosen functions the time complexity of the algorithm is polynomial. Based on this we show an average case exponential separation between classical and quantum time complexity. A perhaps interesting aspect of this work is that, while the extremal case of the Boolean hidden shift problem over so-called bent functions can be reduced to a hidden subgroup problem over an abelian group, the more general case studied here does not seem to allow such a reduction.

description: Elastic and spin-changing inelastic collision cross sections are presented for cold and ultracold magnetically trapped NH. The cross sections are obtained from coupled-channel scattering calculations as a function of energy and magnetic field. We specifically investigate the influence of the intramolecular spin-spin, spin-rotation, and intermolecular magnetic dipole coupling on the collision dynamics. It is shown that $^{15}$NH is a very suitable candidate for evaporative cooling experiments. The dominant trap-loss mechanism in the ultracold regime originates from the intermolecular dipolar coupling term. At higher energies and fields, intramolecular spin-spin coupling becomes increasingly important. Our qualitative results and conclusions are fairly independent of the exact form of the potential and of the size of the channel basis set.

Ni-catalyzed ortho-directed trifluoromethylthiolation of aryl chlorides and bromides
Creators: name: Nguyen, Tin
Publisher: name: University of British Columbia
Year: 2015

description: This thesis describes a novel method to generate trifluoromethanesulfenyl arene or heteroarene products via Ni-catalyzed ortho-selective C-X (X = Cl or Br) activation. Successful C-X activation requires directing groups, but it is highly selective and allows aryl chlorides to be used and shows an appreciable substrate scope. The protocol tolerates various nitrogen-containing directing groups including imines, pyridines, pyrimidines, amides and oxazolines. The method is also compatible with aryl halides bearing substituents with a wide rage of electronic properties, including electron-donating or withdrawing abilities, as well as potentially sensitive functional groups. It also produces trifluoromethylthiolated arenes in good-to-excellent yields at ambient temperatures. [formula omitted]

description: We have spectroscopically discovered a pair of twin, nitrogen-type, hydrogen-rich, Wolf-Rayet stars (WN8-9h) that are both surrounded by circular, mid-infrared-bright nebulae detected with the Spitzer Space Telescope and MIPS instrument. The emission is probably dominated by a thermal continuum from cool dust, but also may contain contributions from atomic line emission. There is no counterpart at shorter Spitzer/IRAC wavelengths, indicating a lack of emission from warm dust. The two nebulae are probably wind-swept stellar ejecta released by the central stars during a prior evolutionary phase. The nebulae partially overlap on the sky and we speculate on the possibility that they are in the early stage of a collision. Two other evolved massive stars have also been identified within the area subtended by the nebulae, including a carbon-type Wolf-Rayet star (WC8) and an O7-8 III-I star, the latter of which appears to be embedded in one of the larger WN8-9h nebulae. The derived distances to these stars imply that they are coeval members of an association lying 4.9 (1.2) kpc from Earth, near the intersection of the Galaxy's Long Bar and the Scutum-Centaurus spiral arm. This new association represents an unprecedented display of complex interactions between multiple stellar winds, outflows, and the radiation fields of evolved massive stars.

description: This poster describes all technical problems in relation with standard UNE-EN ISO 11979-2 when designing and manufacturing a high negative power intraocular lens (IOL). The IOL is -14.00 diopters (D) with neutral spherical aberration, for a real case of a patient with -25.00 D in spectacles plane.

IOL in combination with artificial corneal of IOLA PLUS (Rotlex. Israel), shows a very low modulation transfer function (MTF), which means IOL can not be accepted acording to ISO 11979-2.

Theoretical calculations with the ray tracing software Zemax (Radiant Vision Systems. USA) confirms the low MTF value is due to the long focal length of -14.00 D IOL and IOLA cornea combination, with the IOL having a good optical quality.

description: The momentum dependence of the exciting new Pb + Pb data from LHC qualitatively suggests a perturbative picture interpretation for the energy loss of high-pT particles, but conclusions are difficult to draw due to the lack of 1) a quantitative theoretical calculation constrained by current high precision RHIC data and 2) a lack of control p + p and p + Pb data at LHC. Future measurements of identified heavy quark suppression will provide a novel qualitative tool for determining the dominant physics of the quark-gluon plasma created at RHIC and LHC.

description: We find an exact solution for the problem of electron spin relaxation in a 2D circle with Rashba spin-orbit interaction. Our analysis shows that the spin relaxation in finite-size regions involves three stages and is described by multiple spin relaxation times. It is important that the longest spin relaxation time increases with decrease in system radius but always remains finite. Therefore, at long times, the spin polarization in small 2D systems decays exponentially with a size-dependent rate. This prediction is supported by results of Monte Carlo simulations.

description: A study of the relationship between Lagrangian statistics and flow topology in fluid turbulence is presented. The topology is characterized using the Weiss criterion that provides a simplified tool to partition the flow into topologically different regions: elliptic (vortex dominated), hyperbolic (deformation dominated), and intermediate (turbulent background). The flow corresponds to forced two-dimensional Navier-Stokes turbulence in doubly periodic and circular bounded domains with non-slip boundary conditions. In the double periodic domain, the probability density function (pdf) of the Weiss field exhibits a negative skewness consistent with the fact that in periodic domains the flow is dominated by coherent vortex structures. On the other hand, in the circular domain, the elliptic and hyperbolic regions seem to be statistically similar. We follow a Lagrangian approach and obtain the statistics by tracking large ensembles of passively advected tracers. The pdfs of residence time in the topologically different regions are computed using the Lagrangian Weiss field, i.e., the Weiss field computed along the particles' trajectories. In elliptic and hyperbolic regions, the pdfs of the residence time have self-similar algebraic decaying tails. On the other hand, in the intermediate regions the pdf has exponential decaying tails. The conditional (with respect to the flow topology) pdfs of the Lagrangian velocity exhibit Gaussian behavior in the periodic and in the bounded domains. In contrast to the freely decaying turbulence case, the conditional pdfs of the Lagrangian acceleration in forced turbulence show a comparable level of intermittency in the periodic and the bounded domains. The conditional pdfs of the Lagrangian curvature are characterized, in all cases, by self-similar power law behavior with a decay exponent of order -2.
The arts of empire : re-articulating the coercive consultation event, 1492-1693
Creators: name: Bennett, Matthew David
Publisher: name: University of British Columbia
Year: 2015

description: The following is a transatlantic study of the initial English and Spanish reactions to the problem of language difference in the Americas, focusing on the language related literature of England, Spain, New England, and New Spain, from 1492 to 1693. As part of the arts of empire, which is the use of language technologies for domination, both English and Spanish explorers, historians, and colonists created bilingual word-lists in the primary phase of the language encounter, yet the burgeoning empires’ responses diverged significantly with the deployment of missionary linguistics, resulting in the extremely uneven production of Amerindian grammars. This disparity in descriptive linguistics signals an understudied historical problem that I explain through comparative analysis of the English and Spanish traditions of language policy and language sciences, with particular regard for the effects of the Reformation on monastic communities and the funding of missionary expeditions. Another problem resides in the manner in which linguistic imperialism de-articulates the linguistic data from the language consultant and the historical context. Moving from texts founded on the interview of language slaves to texts requiring more willing collaboration, my response is the creation of an interpretive model, called narrative re-articulation, that combines linguistic data into a virtual syntax in such a way that the moment of language exchange, called the coercive consultation event, is reinserted into the historical narrative. This expands our understanding of the language encounter and linguistic imperialism by identifying language consultants by name, when possible, and by demonstrating the survivance of Amerindian cultures and Amerindian historical figures. Pushing against the early modern de-articulation of the Amerindian consultants from the consultation event, and questioning the reasons for such divergent literary responses to the problem of language difference, I create an interpretive frame for recovering the moment of language exchange and explain the theological and institutional differences between the English and Spanish models for linguistic imperialism in the Americas.

description: In this article we prove that for any saturated fusion system, that the (unique) smallest weakly normal subsystem of it on a given strongly closed subgroup is actually normal. This has a variety of corollaries, such as the statement that the notion of a simple fusion system is independent of whether one uses weakly normal or normal subsystems. We also develop a theory of weakly normal maps, consider intersections and products of weakly normal subsystems, and the hypercentre of a fusion system.
Non-diffusive, non-local transport in fluids and plasmas

description: A review of non-diffusive transport in fluids and plasmas is presented. In the fluid context, non-diffusive chaotic transport by Rossby waves in zonal flows is studied following a Lagrangian approach. In the plasma physics context the problem of interest is test particle transport in pressure-gradient-driven plasma turbulence. In both systems the probability density function (PDF) of particle displacements is strongly non-Gaussian and the statistical moments exhibit super-diffusive anomalous scaling. Fractional diffusion models are proposed and tested in the quantitative description of the non-diffusive Lagrangian statistics of the fluid and plasma problems. Also, fractional diffusion operators are used to construct non-local transport models exhibiting up-hill transport, multivalued flux-gradient relations, fast pulse propagation phenomena, and "tunneling" of perturbations across transport barriers.

description: The COPIM project (Community-led Publication Infrastructure for Monographs) is building community-owned, open systems and infrastructures to enable open access book publishing to flourish. As part of this effort, COPIM is developing Thoth, a database currently in beta that assists open access book publishers in managing their metadata. During this session, we will share more about Thoth’s journey so far, covering four initial use-cases that may be relevant for the Open Science community: Publisher metadata management system – System to manage openly-licensed, standards-compliant bibliographic metadata for open access books. Open Book Collective Platform (COPIM WP2) - Platform to support collective library funding for open access book publishers, infrastrucures and initiatives. Using Thoth to display information about the nature of publications across all participating publishers, infrastructures and initiatives - such as author institutions, subject areas. Open Dissemination Service (COPIM WP5) - Dedicated Service supporting open access book publishers in the areas of dissemination and preservation. Using Thoth to disseminate metadata and files, in various formats (ONIX, CSV, MARC) to a large number of actors part of the open access book supply chain (see also the Thoth Wiki) - such as OAPEN, Project MUSE, JSTOR, Portico. White label publisher website - Complete commercial website for use by scholarly publishers to display and retail their content. Developed and adopted by Open Book Publishers. Using Thoth by calling on its database to display rich book level metadata for a publishers’ content. While the design of Thoth is focused on the immediate needs of publishers, the project is also keeping its eyes on the broader horizon of open & (FAIR) data. How might Thoth continue to serve stakeholders through the identified use-cases? And what other use-cases may be there?

Confirmation of IGR J01363+6610 as a Be X-ray binary with very low quiescent X-ray luminosity

description: The field containing the candidate High Mass X-ray Binary IGR J01363+6610 was observed by XMM-Newton on 2009 July 31 for 28 ks. A Be star was previously suggested as the possible counterpart of the INTEGRAL source, and although Chandra, during a 2007 observation, did not detect an X-ray source at the position of the Be star, we find a variable source (XMMU J013549.5+661243) with an average X-ray flux of 2e-13 ergs/cm2/s (0.2-12 keV, unabsorbed) at this position with XMM-Newton. The spectrum of this source is consistent with a hard power-law with a photon index of 1.4 +/- 0.3 and a column density of 1.5e22 cm^-2 (90% confidence errors). These results, along with our optical investigation of other X-ray sources in the field, makes the association with the Be star very likely, and the 2 kpc distance estimate for the Be star indicates an X-ray luminosity of 9.1e31 ergs/s. This is lower than typical for a Be X-ray binary, and the upper limit on the luminosity was even lower (<1.4e31 ergs/s assuming the same spectral model) during the Chandra observation. We discuss possible implications of the very low quiescent luminosity for the physical properties of IGR J01363+6610.

Combining SMT with theorem proving for AMS verification : analytically verifying global convergence of a digital PLL
Creators: name: Peng, Yan

description: Ubiquitous computer technology is driving increasing integration of digital computing with continuous, physical systems. Examples range from the wireless technology, cameras, motion sensors, and audio IO of mobile devices to sensors and actuators for robots to the analog circuits that regulate the clocks, power supplies, and temperature of CPU chips. While combining analog and digital brings ever increasing functionality, it also creates a design verification challenge: the modeling frameworks for analog and digital design are often quite different, and comprehensive simulations are often impractical. This motivates the use of formal verification: constructing mathematically rigorous proofs that the design has critical properties. To support such verification, I integrated the Z3 “satisfiability modulo theories” (SMT) solver into the ACL2 theorem prover. The capabilities of these two tools are largely complementary – Z3 provides fully automated reasoning about boolean formulas, linear and non-linear systems of equalities, and simple data structures such as arrays. ACL2 provides a very flexible framework for induction along with proof structuring facilities to combine simpler results into larger theorems. While both ACL2 and Z3 have been successfully used for large projects, my work is the first to bring them together. I demonstrate this approach by verifying properties of a clock-generation circuit (called a Phase-Locked Loop or PLL) that is commonly used in CPUs and wireless communication.
Parallel electric field amplification by phase-mixing of Alfven waves

description: Previous numerical studies have identified "phase mixing" of low-frequency Alfven waves as a mean of parallel electric field amplification and acceleration of electrons in a collisionless plasma. Theoretical explanations are given of how this produces an amplification of the parallel electric field, and as a consequence, also leads to enhanced collisionless damping of the wave by energy transfer to the electrons. Our results are based on the properties of the Alfven waves in a warm plasma which are obtained from drift-kinetic theory, in particular, the rate of their electron Landau damping. Phase mixing in a collisionless low-$β$ plasma proceeds in a manner very similar to the visco-resistive case, except for the fact that electron Landau damping is the primary energy dissipation channel. The time and length scales involved are evaluated. We also focus on the evolution of the parallel electric field and calculate its maximum value in the course of its amplification.
Inherent spin density wave instability by vortices in superconductors with strong Pauli effects

description: A novel spin density wave (SDW) instability mechanism enhanced by vortices under fields is proposed to explain the high field and low temperature (HL) phase in CeCoIn$_5$. In the vortex state the strong Pauli effect and the nodal gap conspire to enhance the momentum resolved spectral weight exclusively along the nodal direction over the normal value, providing a favorable nesting condition for SDW with ${\bf Q}=(2k_F, 2k_F, 0.5)$ only under high field ($H$). Observed mysteries of the field-induced SDW confined within $H_{c2}$ are understood consistently, such facts that ${\bf Q}$ is directed to the nodal direction independent of $H$, SDW diminishes under tilting field from the $ab$ plane, and the SDW transition line in $(H,T)$ has a positive slope.
