Non-perturbative Defect One-Point Functions in Planar $\mathcal{N}=4$ Super-Yang-Mills

description: The four dimensional $\mathcal{N}=4$ super-Yang-Mills (SYM) theory exhibits rich dynamics in the presence of codimension-one conformal defects. The new structure constants of the extended operator algebra consist of one-point functions of local operators which are nonvanishing due to the defect insertion and carry nontrivial coupling dependence. We study an important class of half-BPS superconformal defects engineered by D5 branes that share three common directions with the D3 branes and involve Nahm pole configurations for the SYM fields on the D3 brane worldvolume. In the planar large $N$ limit, we obtain non-perturbative results in the 't Hooft coupling $λ$ for the defect one-point functions of both BPS and non-BPS operators, building upon recent progress in localization and integrability methods. For BPS operator insertions in the SYM with D5-brane type boundary or interface, we derive an effective two dimensional defect-Yang-Mills (dYM) theory from supersymmetric localization, which gives an efficient way to extract defect observables and generates a novel matrix model for the defect one-point function. By solving the matrix model in the large $N$ limit, we obtain exact results in $λ$ which interpolate between perturbative Feynman diagram contributions in the weak coupling limit and IIB string theory predictions on $AdS_5\times S^5$ in the strong coupling regime, providing a precision test of AdS/CFT with interface defects. For general non-BPS operators, we develop a non-perturbative bootstrap-type program for integrable boundary states on the worldsheet of the IIB string theory, corresponding to the interface defects in the planar SYM. Such integrable boundary states are constrained by a set of general consistency conditions for which we present explicit solutions that reproduce and extend the known results at weak coupling from integrable spin-chain methods.

description: Purpose: Little is known about the impact medical trainees undertaking global health electives (GHEs) have on host institutions and their communities in low-and middle-income countries. The goal of this study was to explore the relationship dynamics associated with GHEs as perceived by host stakeholders at three sites in sub-Saharan Africa. Method: This case-based interpretive phenomenological study examined stakeholder perspectives in Mwanza, Tanzania, and Mbarara and Rugazi, Uganda, where the University of Calgary, Alberta, Canada has long-standing institutional collaborations. Between September and November 2017, 33 host stakeholders participated in semi-structured interviews and 28 host stakeholders participated in focus group discussions. Participant experiences were analyzed using interpretive phenomenological techniques. Results: The findings revealed that, although GHEs are well-established and a common experience for host stakeholders, their perceptions about who visiting medical trainees (VMTs) are remains indistinct. Participants acknowledged that there are a variety of benefits to GHEs, but overall VMTs appear to benefit the most from this unique learning opportunity. Host stakeholders described significant challenges and burdens of GHEs and recommended ways in which GHEs could be improved. Conclusions: GHEs need to be designed to better embrace ethical engagement and reciprocity with host stakeholders to ensure equity in benefits and responsibilities.

description: We have fabricated carbon nanotube (CN) field-effect transistors with multiple, individually addressable gate segments. The devices exhibit markedly different transistor characteristics when switched using gate segments controlling the device interior versus those near the source and drain. We ascribe this difference to a change from Schottky barrier modulation at the contacts to bulk switching. We also find that the current through the bulk portion is independent of gate length for any gate voltage, offering direct evidence for ballistic transport in semiconducting CNs over at least a few hundred nanometers, even for relatively small carrier velocities.

description: The recent incorporation of large new cooperative borrowers into the U.S. Banks for Cooperatives system has impacted the desired equilibrium of debt to equity capital. Capital program adjustments designed to re-establish equity levels have been implemented without the lenders' determination of their impact on effective interest rates. This paper illustrates that such rates are minimized where the capital revolve period coincides with the length of time required to fully capitalize the new borrowers.
Bihamiltonian structures and quadratic algebras in hydrodynamics and on non-commutative torus

description: We demonstrate the common bihamiltonian nature of several integrable systems. The first one is an elliptic rotator that is an integrable Euler-Arnold top on the complex group GL(N) for any $N$, whose inertia ellipsiod is related to a choice of an elliptic curve. Its bihamiltonian structure is provided by the compatible linear and quadratic Poisson brackets, both of which are governed by the Belavin-Drinfeld classical elliptic $r$-matrix. We also generalize this bihamiltonian construction of integrable Euler-Arnold tops to several infinite-dimensional groups, appearing as certain large $N$ limits of GL(N). These are the group of a non-commutative torus (NCT) and the group of symplectomorphisms $SDiff(T^2)$ of the two-dimensional torus. The elliptic rotator on symplectomorphisms gives an elliptic version of an ideal 2D hydrodynamics, which turns out to be an integrable system. In particular, we define the quadratic Poisson algebra on the space of Hamiltonians on $T^2$ depending on two irrational numbers. In conclusion, we quantize the infinite-dimensional quadratic Poisson algebra in a fashion similar to the corresponding finite-dimensional case.

description: The presence of security vulnerabilities in automotive networks has already been shown by various publications in recent years. Due to the specification of the Controller Area Network (CAN) as a broadcast medium without security mechanisms, attackers are able to read transmitted messages without being noticed and to inject malicious messages. In order to detect potential attackers within a network or software system as early as possible, Intrusion Detection Systems (IDSs) are prevalent. Many approaches for vehicles are based on techniques which are able to detect deviations from specified CAN network behaviour regarding protocol or payload properties. However, it is challenging to detect attackers who secretly connect to CAN networks and do not actively participate in bus traffic. In this paper, we present an approach that is capable of successfully detecting unknown CAN devices and determining the distance (cable length) between the attacker device and our sensing unit based on Time Domain Reflectometry (TDR) technique. We evaluated our approach on a real vehicle network.

description: The purpose of this paper is to investigate the coherence of students' knowledge about heat. The research question concerns an essential theoretical issue for which the two perspectives that coexist in the field, that of coherent and fragmented knowledge respectively, provide different answers and therefore they propose different didactic approaches. A closed-ended questionnaire and Latent Class Analysis (LCA) were implemented to investigate answers consistent with specific mental models. In the present sample of high school students (N = 137), the LCA highlighted only the scientific model as coherent, while the result of the statistical test did not reject the null hypothesis in line with the perspective of fragmented knowledge.

description: A phenomenological description of time evolution of atomic matter waves inside a spiral shaped atomic-wave guide is presented in this report. We study three related topics: (i) the effective Hamiltonian and the time-development equation governing the matter waves; (ii) wavefunctions describing the matter waves in the noncoplanar atom guide; (iii) showing that such wavefunctions obtained is just the eigenstates of the atomic momentum operator. It is believed that both the idea and the results presented here may have relevance to some fundamental problems of atom optics.

description: The ability to accurately predict the finite temperature properties of realistic quantum solids is central to uncovering new phases and engineering materials with novel properties. Nonetheless, there remain comparatively few many-body techniques capable of elucidating the finite temperature physics of solids from first principles. In this work, we take a significant step towards developing such a technique by generalizing our previous, fully ab initio finite temperature Auxiliary Field Quantum Monte Carlo (FT-AFQMC) method to model periodic solids and employing it to uncover the finite temperature physics of periodic hydrogen chains. Based upon our calculations of these chains' many-body thermodynamic quantities and correlation functions, we outline their metal-insulator and magnetic ordering as a function of both H-H bond distance and temperature. At low temperatures approaching the ground state, we observe both metal-insulator and ferromagnetic-antiferromagnetic crossovers at bond lengths between 0.5 and 0.75 Å. We then demonstrate how this low-temperature ordering evolves into a metallic phase with decreasing magnetic order at higher temperatures. By comparing the features we observe to those previously seen in one-dimensional, half-filled Hubbard models at finite temperature and in ground state hydrogen chains, interestingly, we identify signatures of the Pomeranchuk effect in hydrogen chains for the first time and show that spin and charge excitations that typically arise at distinct temperatures in the Hubbard model are indistinguishably coupled in these systems. Beyond qualitatively revealing the many-body phase behavior of hydrogen chains, our efforts shed light on the further theoretical developments that will be required to construct the phase diagrams of the more complex transition metal, lanthanide, and actinide solids of longstanding interest to physicists.

Weak ferromagnetism and other instabilities of the two-dimensional t-t' Hubbard model at Van Hove fillings

description: We investigate magnetic and superconducting instabilities of the two-dimensional t-t' Hubbard model on a square lattice at Van Hove densities from weak to intermediate coupling by means of the two-particle self-consistent approach. We find that as the next-nearest-neighbor hopping |t'| increases from zero, the leading instability is towards an incommensurate spin-density wave whose wave vector moves slowly away from (pi, pi). For intermediate values of |t'|, the leading instability is towards d_{x2-y2}-wave superconductivity. For larger |t'|>0.33t, there are signs of a crossover to ferromagnetism at extremely low temperatures. The suppression of the crossover temperature is driven by Kanamori screening that strongly renormalizes the effective interaction and also causes the crossover temperature to depend only weakly on t'. Electronic self-energy effects for large |t'| lead to considerable reduction of single-particle spectral weight at zero energy at temperatures as high as T<0.1t, an effect that may be detrimental to the existence of a ferromagnetic ground state at weak coupling.

description: To overcome obsolescence of data, a series of papers dealing with the conceptual and operational foundations of major data systems was commissioned by the Economic Statistics Committee of the American Agricultural Economics Association in conjunction with the Statistical Reporting Service, Economic Research Service and Agricultural Marketing Service of the U.S. Department of Agriculture, These papers were presented and discussed extensively at an Agricultural and Rural Data Workshop held in Washington, D. C. May 4-6, 1977. Papers were subsequently revised and are being published in the two Series in which they were organized. Papers prepared by teams in Series A (W. E. Kibler, leader) on Price Reporting and the Caficity of the Food and Fiber Systems are contained in this publication.- Papers prepared by teams in Series B (Gaylord Worden, leader) on Indicators of Economic Well-being of People Engaged in Farming, and Data for Farm and Rural Employment are contained in a separate publication •. ~./ The papers deserve much study--they were carefully prepared by professionals highly qualified to deal with the conceptual and operational issues in data systems where serious data gaps and obsolescence are prominent. The papers will be little more than an academic exercise unless recommendations are used by administrators and policymakers to improve the respective data systems which they address Many of the recommendations can be implemented with little or no additional resources. In cases where additional funds are required, it is the teams' judgments that the additional resources required will provide benefits to users in excess of costs.

On the example of LaVO$_3$ we demonstrate how the temperature and polarization dependences of different components of the optical multiplet are determined by the underlying spin and orbital correlations dictated by the low-energy superexchange Hamiltonian. Thereby the optical data provides deep insight into the complex spin-orbital physics and the role played by orbital fluctuations.

description: In String Theory compactification, branes are often invoked to get the desired form of the radion effective potential. Current popular way of doing this assumes that the introduction of branes will not modify the background geometry in an important way. In this paper, we show by an explicit example that at least in the codimension 2 case, the gravitational backreaction of the brane cannot be neglected in deriving the radion effective potential. Actually, in this case, the presence of branes will have no effect on the dynamics of radion.

description: My graduating paper investigates the purpose of grading and specifically how a no grade assessment approach would work in home economics. Self-study and action research insights gained from assessing two blocks of Foods and Nutrition 9/10 was used, with the intention to help provide other educators interested in no grades assessment with implementation ideas. By explaining to students my philosophy around assessment and gradually changing the strategy to a more no grades approach, by utilizing rubrics, portfolios and written/verbal feedback they slowly adapted to the change and stopped asking about their grade in the course. The findings about the overall success in reducing student stress and increasing student motivation could have implications in how assessment and feedback are given to students at school, particularly in home economics or other elective courses.

description: The stability of electron current sheets embedded within the reconnection exhaust is studied with a 3D fully kinetic particle-in-cell simulation. The electron current layers studied here form self-consistently in a reconnection regime with a moderate guide field, are supported by electron pressure anisotropy with the pressure component parallel to the magnetic field direction larger than the perpendicular components, and extend well beyond electron kinetic scales. In 3D, in addition to drift instabilities common to nearly all reconnection exhausts, the regime considered also exhibits an electromagnetic instability driven by the electron pressure anisotropy. While the fluctuations modulate the current density on small scales, they do not break apart the general structure of the extended electron current layers. The elongated current sheets should therefore persist long enough to be observed both in space observations and in laboratory experiments.

description: Conference (Lecture): American Physics Society (APS) DFD meeting 2019 Seattle In the presented Rayleigh-Bénard convection experiments the turbulent 3d-
 flow of the liquid gallium-indium-tin alloy is investigated by use of ultrasound
 Doppler velocimetry, temperature and contactless inductive flow tomography
 measurements. We reconstruct for the first time near-wall as well as bulk
 flow, momentum and heat transport as well as long-term behaviour of the large-scale liquid
 metal flow at a low Prandtl number of 0.029 and high Rayleigh numbers up
 to 6 · 10e7. Also the influence of a strong magnetic field on the turbulent liquid metal is investigated. The results of the
 experiments are compared to direct numerical simulations and other experiments. These are also
 considered for the interpretation of the measured turbulence statistics.
 Our experiments aim to provide a deeper understanding of the turbulent
 convection and its interaction with magnetic fields in turbulent low Prandtl number
 flows as those in molten steel, aluminium or geo- and astrophysical flows.

Antenatal and postpartum anxiety : Increasing awareness for nurse practitioners in primary care
Creators: name: Austrom, Danae
Publisher: name: The University of British Columbia
Year: 2018

description: Anxiety during the antenatal and postpartum (PP) period is prevalent and can results in adverse ramifications for both mother and child. Research addressing antenatal and PP anxiety lacks in comparison to postpartum depression (PPD), subsequently leading to insufficient screening, misdiagnosis, and poor management of anxiety in maternal women. The literature and guidelines pertaining to how to best care for anxiety in this specialized population is inconsistent. However, the literature consistently identifies that if anxiety is detected early, associated complications and mortality can be reduced. The aim of this literature review is to enhance primary care practitioners (PCP) clinical understanding of perinatal anxiety by outlining the associated risk factors, prevalence, and subsequent consequences. Furthermore, recommendations for screening, diagnosis, treatment, and management are highlighted to improve clinical management of anxiety in perinatal women. This information will be translated into a clinical poster that will be presented at the University of British Columbia’s graduate symposium. The principle objective of this poster will be to improve PCPs knowledge and awareness of prenatal and PP anxiety and help mitigate barriers hindering PCPs from initiating early screening and appropriate tailored treatments in the primary care setting.

 Material examined: IR11 Mazandaran Province, Ramsar, Safa stream near Gavramak village (ca. 37°14’N 49°9’E), 22ºC, 19.07.2003, leg. Pesic, Asadi, Saboori & Akrami (0/1/ 0); IR47 Tehran Province, Elburs Mt., Sijan stream in Sijan village (under Dareh Bridge, ca. 35°55’17N 51°8’54E), 14.08.2003, leg. Pesic & Saboori (0/1/0); IR106 Kermanshah Province, Sar Pol Kangarar stream in Sar Pol Kangarar village (ca. 47º55´E 34º30´N), 27.06.2005, leg.

 Remarks: The populations from Kermanshah Province fit the defination of T. brevirostris poorly (see Cicolani & Di Sabatino 1990). Most idiosoma and gnathosoma measurements are below the minimum values of Italian specimens: Males (female) idiosoma L 650–671 (806), dorsal shield L 581–600 (725), Cx­1 total L 247–269 (300), genital field L 151–159 (178), W 116–125 (168), ejaculatory complex L 234–256, distance genital field–excretory pore 81–97 (187), genital field–caudal idiosoma margin 134–139 (304), gnathosoma ventral L 247–257 (278), chelicera L 272–300, palp total L 263–290 (303); a relatively short postgenital area in males covering 20–21 % of the idiosoma L lies clearly below the minimum values stated for T. brevirostris. In view of the good agreement in proportions and the general shape of idiosoma and gnathosoma (Figs. 1–5) these differences are most probably due to geographical variability.

Multiwavelength Variability Signatures of Relativistic Shocks in Blazar Jets

description: Mildly-relativistic shocks that are embedded in colliding magnetohydrodynamic flows are prime sites for relativistic particle acceleration and production of strongly variable, polarized multi-wavelength emission from relativistic jet sources such as blazars and gamma-ray bursts. The principal energization mechanisms at these shocks are diffusive shock acceleration and shock drift acceleration. In recent work, we had self-consistently coupled shock acceleration and radiation transfer simulations in blazar jets in a basic one-zone scenario. These one-zone models revealed that the observed spectral energy distributions (SEDs) of blazars strongly constrain the nature of the shock layer hydromagnetic turbulence. In this paper, we expand our previous work by including full time dependence and treating two zones, one being the site of acceleration, and the second being a larger emission zone. This construction is applied to multiwavelength flares of the flat spectrum radio quasar 3C 279, fitting snap-shot SEDs and generating light curves that are consistent with observed variability timescales. We also present a generic study for the typical flaring behavior of the BL Lac object Mrk 501. The model predicts correlated variability across all wavebands, but cross-band time lags depending on the type of blazar (FSRQ vs. BL Lac), as well as distinctive spectral hysteresis patterns in all wavelength bands, from mm radio waves to gamma-rays. These evolutionary signatures serve to provide diagnostics on the competition between acceleration and radiative cooling.

description: We report the experimental observation of a lensing effect on a Bose-Einstein condensate expanding in a moving 1D optical lattice. The effect of the periodic potential can be described by an effective mass dependent on the condensate quasi-momentum. By changing the velocity of the atoms in the frame of the optical lattice we induce a focusing of the condensate along the lattice direction. The experimental results are compared with the numerical predictions of an effective 1D theoretical model. Besides, a precise band spectroscopy of the system is carried out by looking at the real-space propagation of the atomic wavepacket in the optical lattice.

Estimation of the jet inclination angle for the TDE Swift J1644+57

description: An estimate of the jet inclination angle relative to the accreting black hole's spin can be useful to probe the jet triggering mechanism and the disc--jet coupling. A Tidal Disruption Event (TDE) of a star by a supermassive spinning black hole provides an excellent astrophysical laboratory to study the jet direction through the possibility of jet precession. In this work, we report a new method to constrain the jet inclination angle $β$ and apply it to the well-sampled jetted TDE Swift J1644+57. This method involves X-ray data analysis and comparisons of jet models with broad properties of the observed X-ray dips, to estimate the upper limit of the extent of the contribution of a plausible jet precession to these X-ray dips. From this limit, we find that $β$ is very likely to be less than $\sim 15^\circ$ for Swift J1644+57. Such a well-constrained jet inclination angle could be useful to probe the jet physics. The main advantage of our method is that it does not need to assume an origin of the observed X-ray dips, and the conclusion does not depend on any particular type of jet precession (e.g., the one due to the Lense-Thirring effect) or any specific value of precession frequency or any particular jet model. These make this method reliable and applicable to other jetted TDEs, as well as to other jetted accreting systems.
