description: We interpret solar flares as events originating from active regions that have reached the Self Organized Critical state, by using a refined Cellular Automaton model with initial conditions derived from observations. Aims: We investigate whether the system, with its imposed physical elements,reaches a Self Organized Critical state and whether well-known statistical properties of flares, such as scaling laws observed in the distribution functions of characteristic parameters, are reproduced after this state has been reached. Results: Our results show that Self Organized Criticality is indeed reached when applying specific loading and relaxation rules. Power law indices obtained from the distribution functions of the modeled flaring events are in good agreement with observations. Single power laws (peak and total flare energy) as well as power laws with exponential cutoff and double power laws (flare duration) are obtained. The results are also compared with observational X-ray data from GOES satellite for our active-region sample. Conclusions: We conclude that well-known statistical properties of flares are reproduced after the system has reached Self Organized Criticality. A significant enhancement of our refined Cellular Automaton model is that it commences the simulation from observed vector magnetograms, thus facilitating energy calculation in physical units. The model described in this study remains consistent with fundamental physical requirements, and imposes physically meaningful driving and redistribution rules.

description: Airbus wurden einige Fälle von elektrischen Notkonfigurationen bei A320-Flugzeugen gemeldet, bei denen beide Triebwerksgeneratoren (Integrated Drive Generator, IDG) aufgrund verschlissener Komponenten in ihrem Konstantdrehzahlgetriebe (Constant Speed Drive, CSD) nacheinander ausfielen. Wie sich herausstellte, können verschlissene IDGs unter bestimmten Umständen zu Problemen mit der Frequenzregelung führen, was dann die elektrische Notkonfiguration aktiviert. Vorbeugende Wartungsarbeiten wurde definiert, um verschlissene IDGs im Voraus zu erkennen. Den Flugbesatzungen werden Empfehlungen gegeben, um eine mögliche elektrische Notkonfiguration im Falle eines Generatorausfalls zu verhindern.
description: Airbus has been notified of several cases of electrical emergency configurations on A320 aircraft, in which both engine generators (Integrated Drive Generator, IDG) failed consecutively due to worn components in their Constant Speed Drive (CSD). As it turns out, worn IDGs can, under certain circumstances, cause frequency control issues, which then activate the electrical emergency configuration. Preventive maintenance tasks have been defined to detect worn IDGs in advance. Flight crews are provided with recommendations to prevent a possible electrical emergency configuration in the event of a generator failure.

description: In high energy heavy ion collisions at RHIC there are important aspects of the medium induced dynamics, that are still not well understood. In particular, there is a broadening and even a double hump structure of the away-side peak appearing in azimuthal correlation studies in Au+Au collisions which is absent in p+p collisions at the same energies. These features are already present but suppressed in p+p collisions: 2 to 3 parton processes produce such structures but are suppressed with respect to 2 to 2 processes. We argue that in A+A collisions the different geometry for the trajectories of 3 as opposed to 2 particles in the final state, together with the medium induced energy loss effects on the different cross sections, create a scenario that enhances processes with 3 particles in the final state, which gives on average this double hump structure.

description: The leading-order electron-atom bremsstrahlung is investigated within the rigorous relativistic approach based on the partial-wave representation of the Dirac wave functions in the external atomic field. Approximating the atomic target by an effective local potential, we calculate the double-differential cross section and the polarization correlations in a wide range of the impact energies. Connection between the bremsstrahlung at the hard-photon end point of the spectrum and the continuum-threshold limit of the radiative recombination is studied. A detailed analysis of the screening effect and the energy dependence of the polarization correlations is presented, with the main focus on the high impact energy region.

description: There's something so very freeing about the world grinding to a halt and suddenly feeling like you have all the time in the world to yourself. You walk down a trail and out into a wide-open, empty field on a day without a single cloud in the sky and you can't hear any trains or cars or bickering couples - just the birds chirping and the trees rustling around you. Both time and the beauty of the natural world feel infinite and it feels like nothing else in the world matters except this feeling of pure bliss. But then someone walks by in a facemask, on the phone to her parents, telling them that if they don't stay inside they may die and she can't bear to lose them this young. And then time doesn't feel infinite anymore, it just feels borrowed from someone else.
It's hard to reconcile how wonderful it feels for time to seemingly slow down and to not have your immediate concerns be all of the personal bullshit you've been dying to escape with the guilt of knowing how many millions of people are suffering right now - all of the people fighting for their lives, whether in a hospital or abusive household or in the wake of being laid off. I feel guilty not being at home, where almost everyone in my family is high-risk in some way, but it's nearly impossible to not feel relieved at being out of a toxic household and having the freedom to really enjoy my days and (try to) focus on my work.
I think I've found peace in using this time to feel and pursue the things that make us want to keep living so badly. Because as fearful and distressed as the world is right now, people are refusing to give up and that passion is what will always save us; we need it.

description: A traditional view on solitons in optical fibers as robust particle-like structures suited for informa- tion transmission has been significantly altered and broadened over the past decade, when solitons have been found to play the major role in generation of octave broad supercontinuum spectra in photonic-crystal and other types of optical fibers. This remarkable spectral broadening is achieved through complex processes of dispersive radiation being scattered from, emitted and transformed by solitons. Thus solitons have emerged as the major players in nonlinear frequency conversion in optical fibers. Unexpected analogies of these processes have been found with dynamics of ultracold atoms and ocean waves. This colloquium focuses on recent understanding and new insights into physics of soliton-radiation interaction and supercontinuum generation.

This introduces a new parameter into the general relativistic cylinder description, the fractional index α. When the fractional index is continued into the negative α region, new behavior is found in the Gott-Hiscock cylinder and in an Israel shell.

The excess of dephasing rate in the gas annealed CVD graphene
Creators: name: Shin, Hyungki
Publisher: name: University of British Columbia
Year: 2018

description: Graphene was expected to prove useful in the field of spintronics because a long spin relaxation time (few micro second) was theoretically expected. However, experimental results using exfoliated graphene have shown that the spin relaxation time is a few orders of magnitude less than the theoretical prediction. It was discovered that the reason for this unexpected shorter spin relaxation time is the presence of magnetic moments on graphene and magnetic moments exist on most forms of graphene. Many theoretical articles expected these magnetic moments to arise due to graphene defects. However, it is not experimentally clear where and how they arise. To answer where and how, we investigates it with dephasing rate (phase relaxation rate) monitored via weak localization on graphene, grown by chemical vapour deposition (CVD graphene). The experiments are performed on field-effect devices made from CVD graphene on various substrates under perpendicularly applied magnetic fields at 4.2 K. The samples are thermally annealed under various conditions, which is a commonplace technique used to clean the surface of graphene. Only the gas annealing induces the additional source of dephasing rate on CVD graphene. However, this could not be seen in before-annealed samples and vacuum annealed samples. Additional experiment confirms that this additional source on gas annealed sample has the magnetic property. The result on this thesis can help answer the origin of magnetic moments on graphene.

description: We present a detailed study of the use of Fabry-Perot (FP) cavities for the spectroscopy of single InAs quantum dots (QDs). We derive optimal cavity characteristics and resolution limits, and measure photoluminescence linewidths as low as 0.9 GHz. By embedding the QDs in a planar cavity, we obtain a sufficiently large signal to actively feed back on the length of the FP to lock to the emission of a single QD with a stability below 2% of the QD linewidth. An integration time of approximately two seconds is found to yield an optimum compromise between shot noise and cavity length fluctuations.

Fluxoid formation: size effects and non-equilibrium universality

description: Simple causal arguments put forward by Kibble and Zurek suggest that the scaling behaviour of condensed matter at continuous transitions is related to the familiar universality classes of the systems at quasi-equilibrium. Although proposed 25 years ago or more, it is only in the last few years that it has been possible to devise experiments from which scaling exponents can be determined and in which this scenario can be tested. In previous work, an unusually high Kibble-Zurek scaling exponent was reported for spontaneous fluxoid production in a single isolated superconducting Nb loop, albeit with low density. Using analytic approximations backed up by Langevin simulations, we argue that densities as small as these are too low to be attributable to scaling, and are conditioned by the small size of the loop. We also reflect on the physical differences between slow quenches and small rings, and derive some criteria for these differences, noting that recent work on slow quenches does not adequately explain the anomalous behaviour seen here.

Applying record value theory in combinatorial optimization with application to environmental statistics
Creators: name: Wang, Yu
Publisher: name: University of British Columbia
Year: 2018

description: We consider the problem of optimal subset selection from a set of correlated random variables. In particular, we consider the associated combinatorial optimization problem of maximizing the determinant of a symmetric positive semidefinite matrix that characterizes the chosen subset. This problem arises in many domains, such as experimental designs, regression modelling, and environmental statistics. In this thesis, we attempt to establish an efficient polynomial-time algorithm for approximating the optimal solution to the problem. Firstly, we employ determinantal point processes, a special class of spatial point processes, to develop an easy-to-implement sampling-based stochastic search algorithm for the task of finding approximations to the combinatorial optimization problem. Secondly, we establish theoretical tools for assessing the quality of those approximations using statistical results from record value theory, the study of record values and related statistics from a sequence of observations.
Simple proof of the robustness of Gaussian entanglement in bosonic noisy channels
Creators: name: Adesso, Gerardo
Publisher: name: arXiv
Year: 2011
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The extremality of Gaussian states is exploited to show that Gaussian states are the most robust, among all possible bipartite continuous-variable states at fixed energy, against disentanglement due to noisy evolutions in Markovian Gaussian channels involving dissipation and thermal hopping. This proves a conjecture raised recently in [M. Allegra, P. Giorda, and M. G. A. Paris, Phys. Rev. Lett. {\bf 105}, 100503 (2010)], providing a rigorous validation of the conclusions of that work. The problem of identifying continuous variable states with maximum resilience to entanglement damping in more general bosonic open system dynamical evolutions, possibly including correlated noise and non-Markovian effects, remains open.

description: The dynamic response of InAs/GaAs self-assembled quantum dots (QDs) to strain is studied experimentally by periodically modulating the QDs with a surface acoustic wave and measuring the QD fluorescence with photoluminescence and resonant spectroscopy. When the acoustic frequency is larger than the QD linewidth, we resolve phonon sidebands in the QD fluorescence spectrum. Using a resonant pump laser, we have demonstrated optical frequency conversion via the dynamically modulated QD, which is the physical mechanism underlying laser sideband cooling a nanomechanical resonator by means of an embedded QD.

We have a new scheme of field-independent thermometry based on quartz tuning fork Helium-3 viscometry which monitors the local temperature of the sample's environment in real time. The operation and measurement circuitry of the quartz viscometer is described in detail. We provide evidence that the temperature of two-dimensional electron gas confined to a GaAs quantum well follows the temperature of the quartz viscometer down to 4mK.

Our main ingredient are the uniform Sobolev inequalities of Kenig, Ruiz, and Sogge.

description: We present deep spectroscopic data for a 24-object subsample of our full 41-object z~0.5 radio galaxy sample in order to investigate the evolution of the Fundamental Plane of radio galaxies. We find that the low-luminosity, FRI-type, radio galaxies in our sample are consistent with the local Fundamental Plane of radio galaxies defined by Bettoni et al. when corrected for simple passive evolution of their stellar populations. However, we find that the higher luminosity, FRII-type radio galaxies are inconsistent with the local Fundamental Plane if only passive evolution is considered, and find evidence for a rotation in the Fundamental Plane at z~0.5 when compared with the local relation. We show that neither passive evolution, nor a mass-dependent evolution in the mass-to-light ratio, nor an evolution in the size of the host galaxies can, by themselves, plausibly explain the observed tilt. However, we suggest that some combination of all three effects, with size evolution as the dominant factor, may be sufficient to explain the difference between the planes. We also find evidence for a correlation between host galaxy velocity dispersion and radio luminosity at the 97% significance level within our sub-sample, although further observations are required in order to determine whether this is different for the FRI and FRII radio sources. Assuming that the M_BH - sigma relation still holds at z~0.5, this implies that radio luminosity scales with black hole mass, in agreement with previous studies.

description: We employ the exact eigenstate basis formalism to study electrical conductivity in graphene, in the presence of short-range diagonal disorder and inter-valley scattering. We find that for disorder strength, $W \ge$ 5, the density of states is flat. We, then, make connection, using the MRG approach, with the work of Abrahams \textit{et al.} and find a very good agreement for disorder strength, $W$ = 5. For low disorder strength, $W$ = 2, we plot the energy-resolved current matrix elements squared for different locations of the Fermi energy from the band centre. We find that the states close to the band centre are more extended and falls of nearly as $1/E_l^{2}$ as we move away from the band centre. Further studies of current matrix elements versus disorder strength suggests a cross-over from weakly localized to a very weakly localized system. We calculate conductivity using Kubo Greenwood formula and show that, for low disorder strength, conductivity is in a good qualitative agreement with the experiments, even for the on-site disorder. The intensity plots of the eigenstates also reveal clear signatures of puddle formation for very small carrier concentration. We also make comparison with square lattice and find that graphene is more easily localized when subject to disorder.

Perfectionistic self-presentation in group therapy : interpersonal behaviours and therapeutic process factors
Creators: name: Kaldas, Janet
Publisher: name: University of British Columbia
Year: 2018

description: The study investigates the associations among perfectionistic self-presentation, interpersonal difficulties, and the process of group therapy based on predictions from the Perfectionism Social Disconnection Model. The study aims to determine whether perfectionistic self-presentation negatively impacts the group therapy process generally and on change over the course of the treatment block. The study also aims to determine whether interpersonal difficulties intervene on the negative associations among perfectionistic self-presentation and group therapy processes. Sixty-nine patients within nine groups attending the Southdown Institute and receiving intensive psychodynamic interpersonal group treatment participated in the study. Patients completed the Perfectionistic Self-Presentation Scale (PSPS; Hewitt et al., 2003), the Inventory of Interpersonal Problems (IIP; Horowitz et al., 1988), the Impact Message Inventory (IMI; Kiesler & Schmidt, 1993) - patient ratings of therapists, the California Psychotherapy Alliance Scales - Group (CALPAS-G; Marmar et al., 1989), and the Curative Climate Inventory (CCI; Furhiman et al., 1986) over the course of one week of daily group therapy. Multilevel modeling analyses were used to analyze direct effects among perfectionistic self-presentation facets and alliance scales and climate factors, as well as indirect effects through interpersonal variables. Perfectionistic self-presentation facets were associated negatively with total alliance and patient contribution scales of the alliance, and positively with interpersonal problems. Perfectionistic self-presentation facets were not associated with change in alliance over the course of the treatment block, with climate factors, or with patients' ratings of therapists' interpersonal impact. Findings suggest that perfectionistic self-presentation influences interpersonal problems and the process of group therapy; however, there was no support for an indirect and intervening role for interpersonal variables in the associations among perfectionistic self-presentation and therapeutic group processes.

description: We give sufficient conditions for the existence of positive travelling wave solutions for multi-dimensional autonomous reaction-diffusion systems with distributed delay. To prove the existence of travelling waves, we give an abstract formulation of the equation for the wave profiles in some suitable Banach spaces, and apply known results about the index of some associated Fredholm operators. After a Liapunov-Schmidt reduction, these waves are obtained via the Banach contraction principle, as perturbations of a positive heteroclinic solution for the associated system without diffusion, whose existence is proven under some requirements. By a careful analysis of the exponential decay of the travelling wave profiles at $-\infty$, their positiveness is deduced. The existence of positive travelling waves is important in terms of applications to biological models. Our method applies to systems of delayed reaction-diffusion equations whose nonlinearities are not required to satisfy a quasi-monotonicity condition. Applications are given, and include the delayed Fisher-KPP equation.

description: We investigated the horizontal and the vertical component of the Evershed flow (EF). To this end, we computed average Stokes V profiles for various velocity classes in penumbrae at different heliocentric angles. Our results show that for blueshifted profiles an additional lobe with the same polarity as the spot is present in the blue side of the average Stokes V profile. The amplitude of the additional lobe grows with increasing blueshift and with increasing heliocentric angle. For small redshifts, the profiles show an additional lobe with the opposite polarity as the spot on the red side of the average Stokes V profile. Even at disk center, the original polarity of the average Stokes V profile is reversed for strong redshifts. The transition between the different types of Stokes V profiles is continuous and indicates that not only the vertical, but also the horizontal EF is a magnetized stream of plasma in a magnetic background field.

Mandibular dental changes following serial and late extraction of mandibular second premolars
Creators: name: Mintenko, Robert
Publisher: name: University of British Columbia
Year: 2018

description: Introduction: 15% of the general population are affected by severe dental crowding where conventional orthodontic treatment involves permanent dentition extractions. An alternative treatment method involves serial extraction in the mixed dentition. There is currently limited research on second premolar serial extraction. Objectives: To determine the changes in occlusal curves and dental tipping that occur from mandibular second premolar serial extraction and early extraction of deciduous mandibular second molars with missing mandibular second premolars. Methods: Records were collected from 85 subjects at 3 timepoints: T0, baseline for the control and serial extraction patients; T1, after extraction and physiologic drift but prior to orthodontic treatment for serial extraction patients, and pre-treatment for the late premolar extraction patients; and T2, after comprehensive orthodontic treatment. Three occlusal curves were measured on digitized mandibular casts by placing best fit spheres at specified landmarks. The long axes of the lower first molar, first premolar, canine and central incisor to the palatal plane were measured on digitized cephalometric radiographs to determine the direction and amount of tipping. Results: At T0, there were no significant differences between groups. At T1, there was significant steepening of Monson’s Sphere and the Curve of Wilson between early and late extraction groups. At T2, the differences in Monson’s sphere and the Curve of Wilson were fully corrected. At T1, there were significant differences in the tipping of lower 6’s, 4’s and 3’s between the early extraction groups compared to the late extraction and control groups. There was no difference in lower incisor tipping between any group. At T2, the differences in tipping were fully corrected. Conclusions: Serial extraction of lower second premolars, or lower deciduous second molars when second premolars were missing, produced steeper occlusal curves and significant tipping of mandibular first molars, first premolars and canines after extraction and physiologic drift (T1). The tipping of teeth and accentuated occlusal curves of Monson’s sphere and the Curve of Wilson were fully corrected following comprehensive fixed orthodontic treatment (T2). Serial extractions involving lower second premolars or lower deciduous second molars did not cause any significant lingual tipping of lower incisors following physiologic drift.

description: There are a number of algebraic classifications of spacetimes in higher dimensions utilizing alignment theory, bivectors and discriminants. Previous work gave a set of necessary conditions in terms of discriminants for a spacetime to be of a particular algebraic type. We demonstrate the discriminant approach by applying the techniques to the Sorkin-Gross-Perry soliton, the supersymmetric and doubly-spinning black rings and some other higher dimensional spacetimes. We show that even in the case of some very complicated metrics it is possible to compute the relevant discriminants and extract useful information from them.

 Notes. The polygonal, dark spores grouped in chains make this species easily distinguishable. Macroscopically, they are similar to Ph. cinereum, Ph. bitectum, and Ph. clavisporum, but these species have non-polygonal free spores. Until now, it was only known from Mexico and Spain (García-Martín et al. 2018). It is the first record for South America. In Peru, it was found in the departments of Ancash and Junin, inhabiting the base of the dead leaves of Agave americana.

description: We investigate the dust associated with the supernova remnant (SNR) N49 in the Large Magellanic Cloud (LMC) as observed with the Herschel Space Observatory. N49 is unusually bright because of an interaction with a molecular cloud along its eastern edge. We have used PACS and SPIRE to measure the far IR flux densities of the entire SNR and of a bright region on the eastern edge of the SNR where the SNR shock is encountering the molecular cloud. Using these fluxes supplemented with archival data at shorter wavelengths, we estimate the dust mass associated with N49 to be about 10 Msun. The bulk of the dust in our simple two-component model has a temperature of 20-30 K, similar to that of nearby molecular clouds. Unfortunately, as a result of the limited angular resolution of Herschel at the wavelengths sampled with SPIRE, the uncertainties are fairly large. Assuming this estimate of the dust mass associated with the SNR is approximately correct, it is probable that most of the dust in the SNR arises from regions where the shock speed is too low to produce significant X-ray emission. The total amount of warm 50-60 K dust is ~0.1 or 0.4 Msun, depending on whether the dust is modeled in terms of carbonaceous or silicate grains. This provides a firm lower limit to the amount of shock heated dust in N49.

description: Oblique propagation and head-on collisions of solitary structures is studied in a dense magnetized plasma comprised of relativistic ultra-cold electrons and positrons and positive dynamic ions using conventional extended multi-scales technique, in the ground of quantum hydrodynamics model. The variations of head-on collision phase-shift as well as the characteristic soliton amplitude and width is evaluated numerically in terms of other plasma parameters such as mass-density, normalized magnetic field strength, its angle with respect to the soliton propagation and the relative positron number-density. The relevance of current investigations, with appropriate plasma parameters for the astrophysical dense magnetized objects such as white-dwarfs, is addressed.

description: We investigate the edge conductance of particles submitted to an Iwatsuka magnetic field, playing the role of a purely magnetic barrier. We also consider magnetic guides generated by generalized Iwatsuka potentials. In both cases we prove quantization of the edge conductance. Next, we consider magnetic perturbations of such magnetic barriers or guides, and prove stability of the quantized value of the edge conductance. Further, we establish a sum rule for edge conductances. Regularization within the context of disordered systems is discussed as well.
