description: We study $C^2$ extremal quasiconformal mappings in space and establish necessary and sufficient conditions for a `localized' form of extremality in the spirit of the work of G. Aronsson on absolutely minimizing Lipschitz extensions. We also prove short time existence for smooth solutions of a gradient flow of QC diffeomorphisms associated to the extremal problem.

description: Thin-film nanocomposites, consisting of silver nanoparticles embedded in a dielectric Teflon\textregistered AF matrix, were synthesized using vapor phase co-deposition. The electrical conductivity of these composites was measured in-situ as a function of film thickness at various metal concentrations. At low metal concentrations (<30%), dielectric behavior and very little change with film thickness was observed. At moderate to high silver loadings (30-80%) a large increase in electrical conductivity was observed as the films grew thicker. As the thickness increased further, the conductivity flattened out. At very high silver content (>90%), fragmented fractal nanoclusters were able to further interconnect to achieve the percolation process and eventually evolve into a metallic continuum with dielectric polymer inclusions.

description: We investigate class field towers of number fields obtained as fixed fields of modular representations of the absolute Galois group of the rational numbers. First, for each $k\in\{12,16,18,20,22,26\}$, we give explicit rational primes $ł$ such that the fixed field of the mod-$ł$ representation attached to the unique normalized cusp eigenforms of weight $k$ on $\Sl_2(\Z)$ has an infinite class field tower. Under a conjecture of Hardy and Littlewood, we further prove that there exist infinitely many such primes for each $k$ (in the above list). Second, given a non-CM curve $E/\Q$, we show that there exists an integer $M_E$ such that the fixed field of the representation attached to the $n$-division points of $E$ has an infinite class field tower for a set of integers $n$ of density one among integers coprime to $M_E$.

description: The spin dependence of the photoelectron tunnel current from free standing GaAs films into out-of- plane magnetized Cobalt films is demonstrated. The measured spin asymmetry (A) resulting from a change in light helicity, reaches +/- 6% around zero applied tunnel bias and drops to +/- 2% at a bias of -1.6 V applied to the GaAs. This decrease is a result of the drop in the photoelectron spin polarization that results from a reduction in the GaAs surface recombination velocity. The sign of A changes with that of the Cobalt magnetization direction. In contrast, on a (nonmagnetic) Gold film A ~ 0%.
Renormalization group analysis of phase transitions in the two dimensional Majorana-Hubbard model
Creators: name: Wamer, Kyle Patrick
Publisher: name: University of British Columbia
Year: 2018

description: A lattice of interacting Majorana modes can occur in a superconducting film on a topological insulator in a magnetic field. The phase diagram as a function of interaction strength for the square lattice was analyzed recently using a combination of mean field theory and renormalization group methods, and was found to include second order phase transitions. One of these corresponds to spontaneous breaking of an emergent U(1) symmetry, for attractive interactions. Despite the fact that the U(1) symmetry is not exact, this transition was claimed to be in a supersymmetric universality class when time reversal symmetry is present and in the conventional XY universality class otherwise. Another second order transition was predicted for repulsive interactions with time reversal symmetry to be in the same universality class as the transition occurring in the Gross-Neveu model, despite the fact that the U(1) symmetry is not exact in the Majorana model. We analyze these phase transitions using a modified epsilon-expansion, confirming the previous conclusions.

description: Early in lockdown like communities many across the country we experienced shortages of food and basic goods. Never enough that we were hungry, but quite a shock to a population that has for many years has had access to everything it wants and does not always need.
Once larger numbers of people were working from home our local shop started to adapt and began to sell products in large quantities such as sourdough bread, dairy products and fresh fruit and vegetables. The change to customer shopping habits meant that customers who would normally have travelled to a supermarket felt safer to shop locally and were happy to support their local shop. In return the shopkeepers did their best to manage their stock and worked hard to make sure the village didn't run out of pasta and toilet roll and to make sure the elderly were looked after during a time when there was great uncertainty and anxiety.
Fresh fruit and vegetables were supplied by the market traders from the local town who collected their goods from Covent Garden at 4am and delivered to the village by 7am for what became a weekly pop-up fruit and veg market. The photograph here is of the village shop decked out for VE day with the pop up market adding colour alongside the Union flags, the French tricolour and the American stars and stripes which all flew in memory of the occasion. The shop staff dressed as land girls and members of the Wantage silver band who are residents of the village played a socially distant selection of melodies from the 1940's. Whilst celebrations were muted the village community held tea parties in their front gardens and the village came to a halt at their gates and front doors as a bugler played the last post at the village war memorial. A very moving tribute during a time of restriction to a time where millions were emerging from war and destruction.

description: We prove the following: (1) if $X$ is ordinary, the Fulton-MacPherson configuration space $X[n]$ is ordinary for all $n$; (2) the moduli of stable $n$-pointed curves of genus zero is ordinary.

This implies the ordinarity of many other well-known configuration spaces (under suitable assumptions).

From Silver Nanoparticles to Thin Films: Evolution of Microstructure and Electrical Conduction

description: Silver nanoparticles embedded in a dielectric matrix are investigated for their potential as broadband-absorbing optical sensor materials. This contribution focuses on the electrical properties of silver nanoparticles at various morphological stages. The electrical current through thin films, consisting of silver nanoparticles, was characterized as a function of film thickness. Three distinct conductivity zones were observed. Two relatively flat zones ("dielectric" for very thin films and "metallic" for films thicker than 300 - 400 Å) are separated by a sharp transition zone where percolation dominates. The dielectric zone is characterized by isolated particle islands with the electrical conduction dominated by a thermally activated tunneling process. The transition zone is dominated by interconnected silver nanoclusters - a small increase of the film thickness results in a large increase of the electrical conductivity. The metallic conductivity zone dominates for thicknesses above 300 - 400 Å.

description: FEUTURE Online Paper No. 3

The aim of this FEUTURE paper is threefold. First, it aims to present in outline the main dynamics that have characterized the security relations between Turkey and the EU since WWII, with a particular emphasis on the post-1999 period. Secondly, it identifies the main drivers that underpin the security manifestations of Turkey-EU relations. Thirdly, and on that footing, it presents the most likely of the three FEUTURE scenarios — conflict, cooperation, and convergence — in the field of security dynamics for the near future. In particular, the paper highlights both the centripetal and centrifugal forces that have marked and continue to mark the relationship. Also, global and regional dynamics and particularly the choices of the United States in the security sphere often drive the relationship even if domestic dynamics have seen a growing salience in the PostCrisis period.

description: We experimentally assess the capabilities of an active, open-loop technique for drag reduction in turbulent wall flows recently introduced by Quadrio et al. [J. Fluid Mech., v.627, 161, (2009)]. The technique consists in generating streamwise-modulated waves of spanwise velocity at the wall, that travel in the streamwise direction. A proof-of-principle experiment has been devised to measure the reduction of turbulent friction in a pipe flow, in which the wall is subdivided into thin slabs that rotate independently in the azimuthal direction. Different speeds of nearby slabs provide, although in a discrete setting, the desired streamwise variation of transverse velocity. Our experiment confirms the available DNS results, and in particular demonstrates the possibility of achieving large reductions of friction in the turbulent regime. Reductions up to 33% are obtained for slowly forward-traveling waves; backward-traveling waves invariably yield drag reduction, whereas a substantial drop of drag reduction occurs for waves traveling forward with a phase speed comparable to the convection speed of near-wall turbulent structures. A Fourier analysis is employed to show that the first harmonics introduced by the discrete spatial waveform that approximates the sinusoidal wave are responsible for significant effects that are indeed observed in the experimental measurements. Practical issues related to the physical implementation of this control scheme and its energetic efficiency are briefly discussed.

description: Lockdown has exposed privilege and has exposed vulnerability. We've learnt things about co-workers' lives of which we formerly had no notion. Do we remember these going forward? Do we forget them and resume the relative anonymity afforded by the common shared space of our previous working environments? Do we become more conscious of what we don't know about each other and treat each other differently, better, with more compassion for the uneven texture of life? The intrusion through Teams of daily work life into our home dwellings has had psychological as well as practical implications, and the former are trickier to unpack than the latter and may have a longer legacy. At least we can hopefully put paid to the idea of an equal normal as everyone's default point of reference.

description: At the beginning of academic year 2007-08, staff in the School of Physics & Astronomy at the University of Glasgow started to implement a number of substantial changes to the first year physics class. The main aims were to improve the academic performance and progression statistics for the class, with early identification of "at-risk" students being one priority. The introduction of novel electronic and computer-based data processing strategies ensured both a quick turnaround time in processing student records and also a much-improved confidence in the accuracy of assessment feedback returned to students. These techniques were a contributory factor in helping raise the pass-rate by ~10% and the direct progression rate by ~13% by the end of 2008-09. The effectiveness of these processes have proved adequate for coping with the unexpected and dramatic 50% increase in class size 2009-10 and are now in the process of being rolled out to other classes within the School

description: Physical constants and cosmological parameters could vary with position. On the largest scales such variations would manifest themselves as gradients across our Hubble volume, leading to dipole-modulation of the cosmic microwave anisotropies. This generically leads to a correlation between adjacent multipoles in the spherical harmonics expansion of the sky, a distinctive signal which should be searched for in future data sets.

Publisher: name: arXiv
Year: 2010
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: We live near a magnetic star whose cycles of activity are driven by dynamo action beneath the surface. In the solar convection zone, rotation couples with plasma motions to build highly organized magnetic fields that erupt at the surface and undergo relatively regular cycles of polarity reversal. Despite our proximity to the Sun, the nature of its dynamo remains elusive, but observations of other solar-type stars show that surface magnetism is a nearly ubiquitous feature. In recent time, numerical simulations of convection and dynamo action have taken tremendous strides forward. Global-scale organization and cyclic magnetism are being achieved by several groups in distinctly different solar and stellar simulations. Here I will talk about advances on the numerical front including wreath-building dynamos which may occupy stellar convection zones. I will discuss the interplay between the new simulations, various classes of mean-field models, and current and upcoming solar and stellar observations.

We show that there is a unique isogeny class of elliptic curves over $\F_{p^2}$ which carries a unique arithmetic spin structure and provides a geometric object of weight 1/2 in the sense of Deligne and Grothendieck. This object is thus a candidate for $\Q(1/4)$.

description: This paper presents a detailed study of the scattering polarization profiles formed under partial frequency redistribution (PRD) in two thermal models of the solar atmosphere. Particular attention is given to understanding the influence of several atmospheric parameters on the emergent fractional linear polarization profiles. The shapes of these $Q/I$ profiles are interpreted in terms of the anisotropy of the radiation field, which in turn depends on the source function gradient that sets the angular variation of the specific intensity. We define a suitable frequency integrated anisotropy factor for PRD that can be directly related to the emergent linear polarization. We show that complete frequency redistribution is a good approximation to model weak resonance lines. We also show that the emergent linear polarization profiles can be very sensitive to the thermal structure of the solar atmosphere and, in particular, to spatial variations of the damping parameter.

Совершенствование технологических и теплотехнических процессов позволяет практически вдвое уменьшить количество избыточных конденсатов и, соответственно, снизить водопотребление и сброс сточных вод.
description: The amount of condensate formed in production depends on the main parameters of the technological and heat engineering processes, in particular on the amount of pumping out of diffusion juice, dry substances of the syrup, which is fed to the boiling of massecuite in vacuum apparatus and the parameters of the evaporation plant. Recently, the sugar industry has begun to intensively introduce the latest technologies that were aimed at increasing production efficiency, reducing fuel consumption and reducing sugar losses in production. Improvement of technological and heat engineering processes makes it possible to practically halve the amount of excess condensates and, accordingly, reduce water consumption and wastewater discharge.

description: The present-day Universe appears to be homogeneous on very large scales. Yet when the casual structure of the early Universe is considered, it becomes apparent that the early Universe must have been highly inhomogeneous. The current paradigm attempts to answer this problem by postulating the inflation mechanism However, inflation in order to start requires a homogeneous patch of at least the horizon size. This paper examines if dynamical processes of the early Universe could lead to homogenization. In the past similar studies seem to imply that the set of initial conditions that leads to homogenization is of measure zero. This essay proves contrary: a set of initial conditions for spontaneous homogenization of cosmological models can form a set of non-zero measure.

description: On the anniversary of the first lockdown, I've been reflecting on how my life has been affected by the pandemic. From the start I've been very fortunate that I've been able to work effectively from home. One major effect of lockdown is the use of such programmes as Teams and Zoom. I've never really heard or use both of them before. The most annoying aspect of these video calling programmes is that the internet signal always seems to cut off at the worse moment, leaving your colleagues with an image of you making a funny face. The isolation is also taking its toll, especially when you have family across the other side of the country. Although video calling and the postal service (for sending presents) does help somewhat. One positive effect on the way I work due to lockdown is that I find more time to explore hobbies such as gardening, and arts and crafts with the time that I save from not commuting into Oxford. With this extra time, I've also managed to create a website and a blog to help convey my passion for plants to the public, and to help them to nurture their interest in all things botanical. I've learnt some new skills as well such as macrame particularly, making hanging planters, knitting and making botanical soaps. I've also found that I've become more house proud, finding small tasks to break up the day such as cleaning the windows and knitting a blanket for the sofa. During lockdown I've found myself focusing on my close family and friends, where I seem to talk more often to them using less time. I hope in the future that I can refine my work-life balance and set aside more time to explore my interests. After lockdown I think I'll be a lot more social.
Monitoring residential woodsmoke in British Columbia communities.
Creators: name: Wagstaff, Matthew
Publisher: name: University of British Columbia
Year: 2018

description: Wood burning is a common home heating method in many communities in British Columbia and an important source of fine particulate matter (PM₂.₅) air pollution. During winter months communities impacted by residential woodsmoke experience high concentrations of PM₂.₅, at levels that have been associated with a wide range of health effects. Characterising levels of woodsmoke within and between communities can support air quality management and reduction of exposures. This project tested novel methods to measure the relative levels and spatial variability of residential woodsmoke PM2.5 using fixed and mobile optical instruments. The methods were applied during the winter heating season (January 5th to March 2nd, 2017) across three communities identified to be impacted by residential woodsmoke from fixed-site monitoring data, and three paired communities without routine monitoring. Continuous monitoring was performed for two weeks at fixed monitoring stations in each monitored community to compare the optical instruments with established methods used to measure PM₂.₅ and woodsmoke. This was combined with nightly mobile monitoring using the same optical instruments, alternating between driving routes around the paired monitored and unmonitored communities to create detailed maps describing woodsmoke levels and variability. The nephelometer (Bsp) and aethalometer (delta C) tested at the fixed-site were strongly correlated with conventional methods of measuring PM₂.₅ (beta attenuation monitor and filter-based) and woodsmoke (levoglucosan). Comparisons between the instruments during mobile monitoring clearly identified times and areas where woodsmoke was dominating PM₂.₅ concentrations. Mobile monitoring indicated considerable spatial variation across all communities and identified hotspot areas with consistently elevated concentrations of both PM₂.₅ and woodsmoke. The spatial variance of PM₂.₅ concentrations was significantly greater than the temporal variance during 71% of the runs, demonstrating the importance of understanding spatial variability when monitoring the air quality impacts of woodsmoke. Strong woodsmoke impacts were found in each community. In general, the unmonitored communities had PM₂.₅ concentrations that were similar to or higher than their partnered monitored communities, despite having smaller sizes and populations. The development of this approach allows for detailed and cost-effective characterisation of woodsmoke in monitored and unmonitored communities, which could inform source control efforts in many Canadian communities.

"Japan is coming here" : reading anticipation for Canada's future(s) in Canadian literary and film representations of the 2011 Japanese tsunami
Creators: name: McGuire-Wood, Lauren
Publisher: name: University of British Columbia
Year: 2018

description: On March 11, 2011, a 9.0 magnitude earthquake rocked Japan, the aftermath of which caused a tsunami that devastated several coastal regions, taking the lives of nearly 16,000 Japanese people and displacing hundreds of thousands more. This disaster also affected countries on the other side of the Pacific Ocean, and the marine debris that washed up on the shores of British Columbia following 3/11 has prompted several Canadian artists to portray this event in their work. This thesis explores the ethical implications of representing the tragedy of another country in three works: the novel A Tale for the Time Being by Ruth Ozeki, short film Debris by John Bolton, and feature-length documentary Lost & Found by John Choi and Nicolina Lanni. This project examines how these Canadian narratives respond to and memorialize the 2011 Japanese tsunami. Employing rhetorical, literary, and ecocritical theories, the thesis uses discourse analysis to consider how national narratives of recovery and safety, as well as orientations toward the future, materialize in these works. It notes the differences that arise between literature and film representations, and between fiction and non-fiction. By tracing conceptions of time and nationhood in the three primary works, this project argues that shifting temporalities within memorials complicate the process of mourning for Japan’s loss, and remind those in Canada, especially BC, that we too could be in this position. This thesis concludes that artists depicting the earthquake and tsunami in their work confront the complications inherent in their own positions and their medium of choice, yet, at times, replicate the very issues they are bringing up. Read together, these works show how narrative representations of disasters play a specific role in the reconstruction of relationships to place and identities following an event so tragic. Additionally, they illuminate just how much memorials are intertwined with hopes and fears of a future which has yet to be determined.

description: In this note we give semiclassical consideration of the role of pulse duration in observation of local field effects in the regime of optical switching. We show that the main parameter governing local field influence is the ratio of peak Rabi frequency corresponding to medium inversion and Lorentz frequency of the medium. To obtain significant local field effect, this parameter should be near unity that is valid only for long enough pulses. We also discuss the role of relaxation and pulse shape in this processes.

description: Our July 2020 wedding plans went on hold when lockdown was announced, as weddings were then banned. A couple of weeks before the date, we heard that weddings could go ahead with 30 people, so we swung into action to make new plans. We will look back at the livestream and photos of our joyful yet socially-distanced wedding and remember this strange year! Though it wasn't all that we had planned, we are really grateful that we could go ahead with the day, and we hope to have more wedding celebrations when we can gather family and friends together.

description: The Ising approximation of the Heisenberg model in a strong magnetic field, with two, three and six spin exchange interactions is studied on a kagome chain. The kagome chain can be considered as an approximation of the third layer of 3He absorbed on the surface of graphite (kagome lattice). By using dynamical approach we have found one and multi-dimensional mappings (recursion relations) for the partition function. The magnetization diagrams are plotted and they show that the kagome chain is separating into four sublattices with different magnetizations. Magnetization curves of two sublattices exhibit plateaus at zero and 2/3 of the saturation field. The maximal Lyapunov exponent for multi-dimensional mapping is considered and it is shown that near the magnetization plateaus the maximal Lyapunov exponent also exhibits plateaus.

description: A small amplitude perturbation analysis is developed to describe the effect of a uniform electric field on the dynamics of a lipid bilayer vesicle in a simple shear flow. All media are treated as leaky dielectrics and fluid motion is described by the Stokes equations. The instantaneous vesicle shape is obtained by balancing electric, hydrodynamic, bending, and tension stresses exerted on the membrane. We find that in the absence of ambient shear flow, it is possible that an applied step--wise uniform DC electric field could cause the vesicle shape to evolve from oblate to prolate over time if the encapsulated fluid is less conducting than the suspending fluid. For a vesicle in ambient shear flow, the electric field damps the tumbling motion leading to a stable tank-treading state.

description: Telescopes often modify the input polarization of a source so that the measured circular or linear output state of the optical signal can be signficantly different from the input. This mixing, or polarization "cross-talk", is defined by the optical system Mueller matrix. We describe here an efficient method for recovering the input polarization state of the light and the full 4 x 4 Mueller matrix of the telescope with an accuracy of a few percent without external masks or telescope hardware modification. Observations of the bright, highly polarized daytime sky using the Haleakala 3.7m AEOS telescope and a coude spectropolarimeter demonstrate the technique.

description: Distributions of the size of the largest component, in particular the large-deviation tail, are studied numerically for two graph ensembles, for Erdoes-Renyi random graphs with finite connectivity and for two-dimensional bond percolation. Probabilities as small as 10^-180 are accessed using an artificial finite-temperature (Boltzmann) ensemble. The distributions for the Erdoes-Renyi ensemble agree well with previously obtained analytical results. The results for the percolation problem, where no analytical results are available, are qualitatively similar, but the shapes of the distributions are somehow different and the finite-size corrections are sometimes much larger. Furthermore, for both problems, a first-order phase transition at low temperatures T within the artificial ensemble is found in the percolating regime, respectively.
