description: We show that a source which radiates in the vacuum of the strongly coupled N=4 SYM theory produces an energy distribution which, in the supergravity approximation, has the same space-time pattern as the corresponding classical distribution: the radiation propagates at the speed of light without broadening. We illustrate this on the basis of several examples: a small perturbation propagating down a steady string, a massless particle falling into AdS_5, and the decay of a time-like wave-packet. A similar observation was made in Phys. Rev. D81 (2010) 126001 for the case of a rotating string. In all these cases, the absence of broadening is related to the fact that the energy backreaction on the boundary arises exclusively from the bulk perturbation at, or near, the boundary. This is so since bulk sources which propagate in AdS_5 at the speed of light do not generate any energy on the boundary. We interpret these features as an artifact of the supergravity approximation, which fails to encode quantum mechanical fluctuations that should be present even in the strong coupling limit. We argue that such fluctuations should enter the dual string theory as longitudinal string fluctuations, which are not suppressed at strong coupling. We heuristically estimate the effects of such fluctuations and argue that they restore the broadening of the radiation, in agreement with expectations from both quantum mechanics and the ultraviolet/infrared correspondence.

Moving pleasure in secondary school physical education
Creators: name: Train, Peter
Publisher: name: University of British Columbia
Year: 2018

description: There is a dearth of research investigating the emotional experiences of students (Pope, 2005) in secondary school physical education and a “deafening silence” (Booth, 2009) regarding the essential role pleasure may play in physical education. Pringle (2010) underscores the potential educational value of “movement pleasure” and this hermeneutic inquiry responds to his call for educators to better understand the way pleasure is socially constructed and managed in their practices. To further understanding of pleasure I draw upon Epicurean philosophy (a practical way of living Life) and apply it to my practice as a secondary school physical education teacher. I create an alternative open framework through which to view events and the experience of curriculum posing the question, “In what ways might a pursuit of pleasure influence curriculum and pedagogy in secondary school physical education?” Epicurean hermeneutic inquiry is the means used to understand student experiences of secondary school physical education. On a weekly basis students share journal entries of their experiences of physical education subsequently unfolding conversations which inform and lead my practice. I concomitantly write my own field notes during and after each physical education class that I later rewrite after reading the students journals and talking with them about their feelings. While studying and drawing from Epicurean philosophy a way of living curriculum in relation to pleasure and happiness (Eudaimonia) I attempt to deepen my understanding of the emotional experiences students encounter in physical education. For example, in one Grade 9 class, I keep close track of and respond to a conversation with one student who is interested in easing the suffering of students who have negative experiences in physical education. The inquiry highlights the influence an embodied and scholarly pursuit of pleasure has on the way curriculum is lived and the tension that exists between natural desires that young people have to move for pleasure (freedom, joy, exultation, and delight) and the developmental lens through which I, as a physical educator, tend to view movement. It provides an alternative and emergent curricular pathway for educators who are interested in investigating the value of “pleasure based physical education.”

description: In this paper, we have implemented and designed a sorting network for reversible logic circuits synthesis in terms of n*n Toffoli gates. The algorithm presented in this paper constructs a Toffoli Network based on swapping bit strings. Reduction rules are then applied by simple template matching and removing useless gates from the network. Random selection of bit strings and reduction of control inputs are used to minimize both the number of gates and gate width. The method produces near optimal results for up to 3-input 3-output circuits.

To better understand the report, analyze the thesis mentioned in the report to identify the facts established in the paper Genomic characterization and infectivity of a novel SARS-like coronavirus in Chinese bats. It can be easily inferred that Chinese People's Liberation Army had been engaged in searching and preparing bat coronaviruses as materials for gain of function experiments. For identifying appropriate material coronaviruses, PLA performed experiment on mice and found ZXC21 bat and ZC45 bat coronaviruses collected in Zhoushan are very ideal. If readers can connect SARS coronaviruses ACE2 functions with ZXC21 bat and ZC45 bat coronaviruses, it may be easier to find answer by reading Yan's reports.

description: Existing sequence alignment algorithms use heuristic scoring schemes which cannot be used as objective distance metrics. Therefore one relies on measures like the p- or log-det distances, or makes explicit, and often simplistic, assumptions about sequence evolution. Information theory provides an alternative, in the form of mutual information (MI) which is, in principle, an objective and model independent similarity measure. MI can be estimated by concatenating and zipping sequences, yielding thereby the "normalized compression distance". So far this has produced promising results, but with uncontrolled errors. We describe a simple approach to get robust estimates of MI from global pairwise alignments. Using standard alignment algorithms, this gives for animal mitochondrial DNA estimates that are strikingly close to estimates obtained from the alignment free methods mentioned above. Our main result uses algorithmic (Kolmogorov) information theory, but we show that similar results can also be obtained from Shannon theory. Due to the fact that it is not additive, normalized compression distance is not an optimal metric for phylogenetics, but we propose a simple modification that overcomes the issue of additivity. We test several versions of our MI based distance measures on a large number of randomly chosen quartets and demonstrate that they all perform better than traditional measures like the Kimura or log-det (resp. paralinear) distances. Even a simplified version based on single letter Shannon entropies, which can be easily incorporated in existing software packages, gave superior results throughout the entire animal kingdom. But we see the main virtue of our approach in a more general way. For example, it can also help to judge the relative merits of different alignment algorithms, by estimating the significance of specific alignments.

description: Resolving the tension between quantum superpositions and the uniqueness of the classical world is a major open problem. One possibility, which is extensively explored both theoretically and experimentally, is that quantum linearity breaks above a given scale. Theoretically, this possibility is predicted by collapse models. They provide quantitative information on where violations of the superposition principle become manifest. Here we show that the lower bound on the collapse parameter lambda, coming from the analysis of the human visual process, is ~ 7 +/- 2 orders of magnitude stronger than the original bound, in agreement with more recent analysis. This implies that the collapse becomes effective with systems containing ~ 10^4 - 10^5 nucleons, and thus falls within the range of testability with present-day technology. We also compare the spectrum of the collapsing field with those of known cosmological fields, showing that a typical cosmological random field can yield an efficient wave function collapse.

description: Quantum corrections generate a quadratically divergent mass term for the Higgs boson in the Standard Model. Thus, if the Higgs boson has a mass of order 100 GeV, it implies the presence of a cut-off of the theory around TeV scale, and some particles associated with the new physics may appear around the cut-off scale $Λ$. However, if $Λ$ is several TeV, it may be difficult to find such particles at the LHC. In this paper, we consider a situation in which the new physics provides relatively light particles compared with the scale $Λ$. In such a situation, we show that diphoton event and four lepton event by the decay of the Higgs and/or a new particle have naturally large cross section, and LHC may test the new physics in a considerably broad parameter region even if $Λ$ is several TeV.

Polarization and two-photon spectroscopy of xenon for optical magnetometry
Creators: name: Miller, Eric Robert
Publisher: name: University of British Columbia
Year: 2018

description: This dissertation presents work in the hyperpolarization of ¹²⁹Xe and in precision Xe spectroscopy using two-photon absorption. Both projects contribute to the development of optical magnetometry using ¹²⁹Xe. Motivating this work is the proposal for a new ¹²⁹Xe-based comagnetometer at TRIUMF for experiments searching for a permanent electric dipole moment of the neutron. In these proposed experiments ¹²⁹Xe will occupy the same experimental volume as ultracold neutrons and be used to measure drifts in an applied magnetic field. A scheme is described for optical magnetometry which involves the production of polarized ¹²⁹Xe followed by measurements using two-photon laser induced fluorescence as a probe. Spin exchange optical pumping is used to produce polarized ¹²⁹Xe, which is a necessary precursor for optical magnetometry. The first part of this dissertation presents the implementation and operation of a polarizer using a diode laser and a Xe-Rb-N₂-He mixture. We have achieved hyperpolarization of ¹²⁹Xe up to PXe ~ 5%, which is many times greater than the thermal equilibrium polarization. We measure the nuclear magnetic resonance signal from polarized ¹²⁹Xe using a low-field detection apparatus, and compare the signal with predictions based on a rate equation model. Efforts to optimize the degree of polarization in the present apparatus are described, as well as purification of Xe gas through freezeout. The second part of this dissertation presents precision spectroscopy on natural abundance Xe using a narrow linewidth laser. The two-photon transition studied here ( 5p⁵(²P₃/₂)6p²[3/2]₂ ← 5p⁶ (¹S₀)) is suitable to probe the ground state ¹²⁹Xe polarization for optical magnetometry. We present the implementation of a CW laser source with narrow linewidth followed by the excitation of Xe two-photon absorption in a resonant cavity. We measure and report hyperfine constants and isotope shifts from the observed laser induced fluorescence spectra. From the observed signal to noise ratio we estimate a magnetometric sensitivity based on this detection scheme over a range of Xe pressures. Results from this two-photon absorption measurement are essential in the determination of parameters for final implementation in the nEDM experiment.

description: The growth rate of long wavelength kinetic instabilities arising due to the interaction of a collimated beam of relativistic particles and a cold unmagnetized plasma are calculated in the ultra relativistic limit. For sufficiently culminated beams, all long wave-length modes are shown to be Weibel-unstable, and a simple analytic expression for their growth rate is derived. For large transverse velocity spreads, these modes become stable. An analytic condition for stability is given. These analytic results, which generalize earlier ones given in the literature, are shown to be in agreement with numerical solutions of the dispersion equation and with the results of novel PIC simulations in which the electro-magnetic fields are restricted to a given k-mode. The results may describe the interaction of energetic cosmic rays, propagating into the far upstream of a relativistic collisionless shock, with a cold unmagnetized upstream. The long wavelength modes considered may be efficient in deflecting particles and could be important for diffusive shock acceleration. It is shown that while these modes grow in relativistic shocks propagating into electron-positron pair plasmas, they are damped in relativistic shocks propagating into electron-proton plasmas with moderate Lorenz factors Γ_{sh}\lesssim 100. If these modes dominate the deflection of energetic cosmic rays in electron-positron shocks, it is argued that particle acceleration is suppressed at shock frame energies that are larger than the downstream thermal energy by a factor greater than the shock Lorentz factor.

description: Muon tomography based on the measurement of multiple scattering of atmospheric cosmic ray muons is a promising technique for detecting and imaging heavily shielded high-Z nuclear materials such as enriched uranium. This technique could complement standard radiation detection portals currently deployed at international borders and ports, which are not very sensitive to heavily shielded nuclear materials. We image small targets in 3D using $2\times 2 \times 2 mm^3$ voxels with a minimal muon tomography station prototype that tracks muons with Gas Electron Multiplier (GEM) detectors read out in 2D with x-y microstrips of 400 micron pitch. With preliminary electronics, the GEM detectors achieve a spatial resolution of 130 microns in both dimensions. With the next GEM-based prototype station we plan to probe an active volume of ~27 liters. We present first results on reading out all 1536 microstrips of a $30 \times 30 cm^2$ GEM detector for the next muon tomography prototype with final frontend electronics and DAQ system. This constitutes the first full-size implementation of the Scalable Readout System (SRS) recently developed specifically for Micropattern Gas Detectors by the RD51 collaboration. Design of the SRS and first performance results when reading out GEM detectors are presented.

A transient thermal model for machining

Publisher: name: University of British Columbia
Year: 2018

description: Prediction of temperature in the tool, chip and workpiece surface layer is essential for tool design and the selection of most productive cutting conditions which yield the desired tool life and acceptable residual stresses left on the machined part. This thesis presents a comprehensive, finite difference method based numerical model on simulating the temperature distribution in the chip, tool, and finished workpiece surface layer as a function of material properties, cutting speed, feed rate and tool-workpiece engagement period. The heat is generated in the primary shear zone where the chip is sheared from the metal, in the secondary zone where the chip sticks and slides on the rake face, and in the tertiary zone where cutting-edge ploughs the workpiece surface. The chip, layer of the workpiece surface and the tool edge are meshed into discrete elements. The heat is transferred to the stationary tool, and dynamically moving chip and workpiece surface by conforming heat balance equations within each element. A finite difference technique with implicit time discretization is used to solve heat balance equations of the temperature fields on the tool, workpiece, and chip. Anisotropic material properties can be considered in the model which allows the inclusion of a coating layer on the tool. The proposed model allows two and three-dimensional heat transfer, hence it can be used to predict the temperature distribution in turning, drilling and milling operations. The continuous machining processes such as turning generate constant heat, so the temperature reaches a steady state after a transient period. The intermittent operations such as milling generate time-varying and periodic heat, hence the temperature variation is always in a transient state. The proposed model is experimentally validated with the data found in the literature and experiments conducted by the author at the industrial partner’s (Sandvik Coromant AB, Sweden) research facility. Experimental validations cover uncoated, single and multi-layer coated tools to simulate continuous turning, interrupted turning and milling operations. The proposed model is able to predict the temperature with less than 20% error in most of the validated cases.
Dynamics of operator size distribution in q-local quantum Brownian SYK and spin models

description: We study operator dynamics in Brownian quantum many-body models with $q$-local interactions. The operator dynamics are characterized by the time-dependent size distribution, for which we derive an exact master equation in both the Brownian Majorana Sachdev-Ye-Kitaev (SYK) model and the spin model for general $q$. This equation can be solved numerically for large systems. Additionally, we obtain the analytical size distribution in the large $N$ limit for arbitrary initial conditions and $q$. The distributions for both models take the same form, related to the $χ$-squared distribution by a change of variable, and strongly depend on the initial condition. For small initial sizes, the operator dynamics are characterized by a broad distribution that narrows as the initial size increases. When the initial operator size is below $q-2$ for the Majorana model or $q-1$ for the spin model, the distribution diverges in the small size limit at all times. The mean size of all operators, which can be directly measured by the out-of-time ordered correlator, grows exponentially during the early time. In the late time regime, the mean size for a single Majorana or Pauli operator for all $q$ decays exponentially as $t e^{-t}$, much slower than all other operators, which decay as $e^{-t}$. At finite $N$, the size distribution exhibits modulo-dependent branching within a symmetry sector for the $q \geq 8$ Majorana model and the $q \geq 4$ spin model. Our results reveal universal features of operator dynamics in $q$-local quantum many-body systems.

description: Mixed anomaly and gauge mediation ("gaugomaly'' mediation) gives a natural solution to the SUSY flavor problem with a conventional LSP dark matter candidate. We present a minimal version of gaugomaly mediation where the messenger masses arise directly from anomaly mediation, automatically generating a messenger scale of order 50 TeV. We also describe a simple relaxation mechanism that gives rise to realistic mu and B mu terms. B is naturally dominated by the anomaly-mediated contribution from top loops, so the mu/B mu sector only depends on a single new parameter. In the minimal version of this scenario the full SUSY spectrum is determined by two continuous parameters (the anomaly- and gauge-mediated SUSY breaking masses) and one discrete parameter (the number of messengers). We show that these simple models can give realistic spectra with viable dark matter.

description: Online social media are complementing and in some cases replacing person-to-person social interaction and redefining the diffusion of information. In particular, microblogs have become crucial grounds on which public relations, marketing, and political battles are fought. We introduce an extensible framework that will enable the real-time analysis of meme diffusion in social media by mining, visualizing, mapping, classifying, and modeling massive streams of public microblogging events. We describe a Web service that leverages this framework to track political memes in Twitter and help detect astroturfing, smear campaigns, and other misinformation in the context of U.S. political elections. We present some cases of abusive behaviors uncovered by our service. Finally, we discuss promising preliminary results on the detection of suspicious memes via supervised learning based on features extracted from the topology of the diffusion networks, sentiment analysis, and crowdsourced annotations.

description: Channel conductance measurements can be used as a tool to study thermally activated electron transport in the sub-threshold region of state-of-art FinFETs. Together with theoretical Tight-Binding (TB) calculations, this technique can be used to understand the evolution of source-to-channel barrier height (Eb) and of active channel area (S) with gate bias (Vgs). The quantitative difference between experimental and theoretical values that we observe can be attributed to the interface traps present in these FinFETs. Therefore, based on the difference between measured and calculated values of (i) S and (ii) |dEb/dVgs| (channel to gate coupling), two new methods of interface trap density (Dit) metrology are outlined. These two methods are shown to be very consistent and reliable, thereby opening new ways of analyzing in situ state-of-the-art multi-gate FETs down to the few nm width limit. Furthermore, theoretical investigation of the spatial current density reveal volume inversion in thinner FinFETs near the threshold voltage.

description: AR Aur is the only eclipsing binary known to contain a HgMn star, making it an ideal case for a detailed study of the HgMn phenomenon. HgMn stars are a poorly understood class of chemically peculiar stars, which have traditionally been thought not to possess significant magnetic fields. However, the recent discovery of line profile variability in some HgMn stars, apparently attributable to surface abundance patches, has brought this belief into question. In this paper we investigate the chemical abundances, line profile variability, and magnetic field of the primary and secondary of the AR Aur system, using a series of high resolution spectropolarimetric observations. We find the primary is indeed a HgMn star, and present the most precise abundances yet determined for this star. We find the secondary is a weak Am star, and is possibly still on the pre-main sequence. Line profile variability was observed in a range of lines in the primary, and is attributed to inhomogeneous surface distributions of some elements. No magnetic field was detected in any observation of either stars, with an upper limit on the longitudinal magnetic field in both stars of 100 G. Modeling of the phase-resolve longitudinal field measurements leads to a 3 sigma upper limit on any dipole surface magnetic field of about 400 G.

description: In this note, we use the Lopez-Ros deformation introduced in [9] to show that any embedded genus-one helicoid must be symmetric with respect to rotation by 180 degrees around a normal line. This partially answers a conjecture of Bobenko from [3]. We also show this symmetry holds for an embedded genus-k helicoid $Σ$, provided the underlying conformal structure of $Σ$ is hyperelliptic.

description: From Introduction: 'The past eight years have seen racial justice come to the forefront of the American social discussion, especially with the Black Lives Matter movement. Since Kaepernick’s resistance in 2016, racial awareness for equality and the Black Lives Matter movement has increased in the sports world. Most notably, this past summer, the police killing of George Floyd provoked the NFL to finally make a public stand against racism through its “It Takes All of Us” campaign. Data regarding the league’s social media support for the Black Lives Matter movement and its political market can give insight to the NFL’s response into player activism.'
Determination of the atom’s excited-state fraction in a magneto-optical trap

description: This thesis introduces an empirical method for determining and controlling the excited-state fraction of atoms in a magneto-optical trap (MOT), which is essential for the use of cold atoms as a sensor when they are held in a MOT since their interactions with other particles and fields are quantum state dependent. A four-level theoretical atomic model was used to describe the transitions of the atoms in a MOT, and the fluorescence emitted from a fixed number of atoms under different laser conditions were measured to determine the saturation parameters empirically. Two saturation parameters P_sat= 1.15 (0.06) mW and P_r,sat= 2.05 (0.59) mW were successfully extracted from the model, and the excited-state fraction in the four-level model was accurately calculated as a function of the MOT trap parameters, which ranges from 0.045 to 0.415 for the experimental settings currently available. We also observed minor deviations from the four-level model for the photon scattering rate, and a hypothesis of atom pinning under high powers was proposed to explain the problem. We plan to use this simple excited-state fraction determination method to distinguish the ground and excited state collision cross section of Rubidium atoms with species in residual gas of the vacuum. This is the first step to establishing atom loss rates from a MOT as an atomic primary pressure standard.

description: We present X-ray and optical data on the Be/X-ray binary (BeXRB) pulsar IGR J01054-7253 = SXP11.5 in the Small Magellanic Cloud (SMC). Rossi X-ray Timing Explorer (RXTE) observations of this source in a large X-ray outburst reveal an 11.483 +/- 0.002s pulse period and show both the accretion driven spin-up of the neutron star and the motion of the neutron star around the companion through Doppler shifting of the spin period. Model fits to these data suggest an orbital period of 36.3 +/- 0.4d and Pdot of (4.7 +/- 0.3) x 10^{-10} ss^{-1}. We present an orbital solution for this system, making it one of the best described BeXRB systems in the SMC. The observed pulse period, spin-up and X-ray luminosity of SXP11.5 in this outburst are found to agree with the predictions of neutron star accretion theory. Timing analysis of the long-term optical light curve reveals a periodicity of 36.70 +/- 0.03d, in agreement with the orbital period found from the model fit to the X-ray data. Using blue-end spectroscopic observations we determine the spectral type of the counterpart to be O9.5-B0 IV-V. This luminosity class is supported by the observed V-band magnitude. Using optical and near-infrared photometry and spectroscopy, we study the circumstellar environment of the counterpart in the months after the X-ray outburst.

The Extracellular Matrix Proteins Laminin and Fibronectin Contain Binding Domains for Human Plasminogen and Tissue Plasminogen Activator.

description: This study describes the binding of plasminogen and tissue-type plasminogen activator (t-PA) to the extracellular matrix proteins fibronectin and laminin. Plasminogen bound specifically and saturably to both fibronectin and laminin immobilized on microtiter wells,with Kd(app) values of 115 and 18 nM,respectively. Limited proteolysis by endoproteinase V8 coupled with ligand blotting analysis showed that both plasminogen and t-PA preferentially bind to a 55-kDa fibronectin fragment and a 38-kDa laminin fragment. Amino acid sequence analysis demonstrated that the 5-kDa fragment originates with the fibronectin amino terminus whereas the laminin fragment was derived from the carboxyl-terminal globular domain of the laminin A chain. Ligand blotting experiments using isolated plasminogen domains were also used to identify distinct regions of the plasminogen molecule involved in fibronectin and laminin binding. Solution phase fibronectin binding to immobilized plasminogen was mediated primarily via lysine binding site-dependent interactions with plasminogen kringles 1-4. Lysine binding site-dependent binding of soluble laminin to immobilized plasminogen kringles 1-5 as well as an additional lysine binding site-independent interaction between mini-plasminogen and the 38-kDa laminin A chain fragment were also observed. These studies demonstrate binding of plasminogen and tissue-type plasminogen activator to specific regions of the extracellular matrix glycoproteins laminin and fibronectin and provide further insight into the mechanism of regulation of plasminogen activation by components of the extracellular matrix.

description: Ly-alpha emitters (LAEs) are seen everywhere in the redshift domain from local to z~7. Far-infrared (FIR) counterparts of LAEs at different epochs could provide direct clues on dust content, extinction, and spectral energy distribution (SED) for these galaxies. We search for FIR counterparts of LAEs that are optically detected in the GOODS-North field at redshift z~2.2 using data from the Herschel Space Telescope with the Photodetector Array Camera and Spectrometer (PACS). The LAE candidates were isolated via color-magnitude diagram using the medium-band photometry from the ALHAMBRA Survey, ancillary data on GOODS-North, and stellar population models. According to the fitting of these spectral synthesis models and FIR/optical diagnostics, most of them seem to be obscured galaxies whose spectra are AGN-dominated. From the analysis of the optical data, we have observed a fraction of AGN or composite over source total number of ~0.75 in the LAE population at z~2.2, which is marginally consistent with the fraction previously observed at z=2.25 and even at low redshift (0.2

description: According to a theorem of Poincare, the solutions to differential equations are analytic functions of (and therefore have Taylor expansions in) the initial conditions and various parameters providing the right sides of the differential equations are analytic in the variables, the time, and the parameters. We describe how these Taylor expansions may be obtained, to any desired order, by integration of what we call the complete variational equations. As illustrated in a Duffing equation stroboscopic map example, these Taylor expansions, truncated at an appropriate order thereby providing polynomial approximations, can well reproduce the behavior (including infinite period doubling cascades and strange attractors) of the solutions of the underlying differential equations.
