description: Nitride perovskites are supposed to exhibit excellent properties as oxide analogues and may even have better performance in specific fields for their more covalent characters. However, till now, very limited nitride perovskites have been reported. In this work, a nitride perovskite LaMoN$_3$ has been systematically studied by first-principles calculations. The most interesting physical property is its ferroelectric $R3c$ phase, which can be stabilized under a moderate hydrostatic pressure ($\sim1.5$ GPa) and probably remain meta-stable under the ambient condition. Its ferroelectric polarization is considerable large, $80.3$ $μ$C/cm$^2$, driven by the nominal $4d^0$ rule of Mo$^{6+}$, and the covalent hybridization between Mo's $4d$ and N's $2p$ orbitals is very strong. Our calculation not only predicts a new ferroelectric material with prominent properties, but also encourages more studies on pressure engineering of functional nitrides.

description: According to a model of quantum cosmology the maximum number of degrees of freedom allowed in our three dimensions was determined by the size of seven extra dimensions in an initial excited state before inflation. The size of the extra dimensions can be inferred from a simple scheme for unifying the strong force and gravity. Coupled with the Bekenstein-Hawking entropy bound, these considerations lead to a scaling law for the cosmological constant that has been proposed independently by several authors.

description: We study the aerodynamics of a flapping flexible wing with a two-vein pattern that mimics the elastic response of insect wings in a simplified manner. The experiments reveal a non-monotonic variation of the thrust force produced by the wings when the angle between the two veins is varied. An optimal configuration is consistently reached when the two veins are spaced at an angle of about 20 degrees. This value is in the range of what has been measured in the literature for several insect species. The deformation of the wings is monitored during the experiment using video recordings, which allows to pinpoint the physical mechanism behind the non-monotonic behaviour of the force curve and the optimal distribution of the vein network in terms of propulsive force.

On May 2, 2008, Tropical Cyclone Nargis killed over 130,000 people in southern Myanmar making it the 8th deadliest cyclone of all time. A better understanding of the mechanisms in the early stages of development of tropical cyclones, such as the role of latent and sensible heat fluxes from the ocean, could help forecast modelers better understand the physics of the cyclogenesis, improve the model forecasts and ultimately gain a greater lead time in detecting and predicting cyclones. We conducted two experiments using the Weather Research and Forecast (WRF) model version 3.3.1 to determine the impact of surface fluxes on the genesis of Cyclone Nargis during a 60-hour forecast. The two experiments included: a control run (CNTRL), where the model forecast had full physics, including sensible and latent heat fluxes from the surface, and a no flux run (NOFLX), which turned off both surface sensible heat and latent heat fluxes. The CNTRL produced a strong cyclone, with a maximum wind of 65 knots (33.4 m/s) and a minimum pressure of 955 hPa. The NOFLX produced a weak cyclone with a maximum wind of 25 knots (12.9 m/s) and a minimum pressure of 1002 hPa. Thus major factors in the genesis of Cyclone Nargis were the surface latent and sensible heat fluxes over the ocean, where the sea-surface temperature was above normal.

description: A systematic method to obtain the effective Lagrangian on the BPS background in supersymmetric gauge theories is worked out, taking domain walls and vortices as concrete examples. The Lagrangian in terms of the superfields for four preserved SUSY is expanded in powers of the slow-movement parameter lambda. The expansion gives the superfield form of the BPS equations at {O}(lambda^0), and all the fluctuation fields at {O}(lambda^1). The density of the Kaehler potential for the effective Lagrangian follows as an automatic consequence of the lambda expansion with manifest (four preserved) SUSY.

description: We investigate the effects of the purely toroidal magnetic field on the equilibrium structures of the relativistic stars. The master equations for obtaining equilibrium solutions of relativistic rotating stars containing purely toroidal magnetic fields are derived for the first time. To solve these master equations numerically, we extend the Cook-Shapiro-Teukolsky scheme for calculating relativistic rotating stars containing no magnetic field to incorporate the effects of the purely toroidal magnetic fields. By using the numerical scheme, we then calculate a large number of the equilibrium configurations for a particular distribution of the magnetic field in order to explore the equilibrium properties. We also construct the equilibrium sequences of the constant baryon mass and/or the constant magnetic flux, which model the evolution of an isolated neutron star as it loses angular momentum via the gravitational waves. Important properties of the equilibrium configurations of the magnetized stars obtained in this study are summarized as follows ; (1) For the non-rotating stars, the matter distribution of the stars is prolately distorted due to the toroidal magnetic fields. (2) For the rapidly rotating stars, the shape of the stellar surface becomes oblate because of the centrifugal force. But, the matter distribution deep inside the star is sufficiently prolate for the mean matter distribution of the star to be prolate. (3) The stronger toroidal magnetic fields lead to the mass-shedding of the stars at the lower angular velocity. (4) For some equilibrium sequences of the constant baryon mass and magnetic flux, the stars can spin up as they lose angular momentum.

description: Steady-state observables, such as occupation numbers and currents, are crucial experimental signatures in open quantum systems. The time-convolutionless (TCL) master equation, which is both exact and time-local, is an ideal candidate for the perturbative computation of such observables. We develop a diagrammatic approach to evaluate the steady-state TCL generator based on operators rather than superoperators. We obtain the steady-state occupation numbers, extend our formulation to the calculation of currents, and provide a simple physical interpretation of the diagrams. We further benchmark our method on a single non-interacting level coupled to Fermi reservoirs, where we recover the exact expansion to next-to-leading order. The low number of diagrams appearing in our formulation makes the extension to higher orders accessible. Combined, these properties make the steady-state time-convolutionless master equation an effective tool for the calculation of steady-state properties in open quantum systems.

Concerns about fossil fuel supplies and an ever-increasing demand for energy have prompted the search for alternative power sources. One option is the ocean, a power-dense and renewable source of energy; but its capacity to meet human energy demands is poorly understood. While raw wave energy resources have been investigated at many scales, little is known about where and how much power can be extracted. Even less is known about the energy available in ocean currents, especially on a global scale. This study assessed where significant amounts of energy in ocean waves and currents are available for human use. Global wave and current energy were calculated from model data and mapped. To assess the recoverable energy around the United States, population and marine protected area data were combined with technical specifications for the Pelamis and SeaGen energy convertors, and the dollar values of the energy were estimated. The results suggest that promising amounts of wave and current energy are available both globally and around the United States. Potential locations for wave and current energy farms appear to exist on the Pacific, Atlantic, and Gulf Coasts of the U.S. Further research in this area may lead to greater support for developing, testing, and deploying ocean energy converter technology.

description: An accurate and substantial dataset is essential for training a reliable and well-performing model. However, even manually annotated datasets contain label errors, not to mention automatically labeled ones. Previous methods for label denoising have primarily focused on detecting outliers and their permanent removal - a process that is likely to over- or underfilter the dataset. In this work, we propose AGRA: a new method for learning with noisy labels by using Adaptive GRAdient-based outlier removal. Instead of cleaning the dataset prior to model training, the dataset is dynamically adjusted during the training process. By comparing the aggregated gradient of a batch of samples and an individual example gradient, our method dynamically decides whether a corresponding example is helpful for the model at this point or is counter-productive and should be left out for the current update. Extensive evaluation on several datasets demonstrates AGRA's effectiveness, while a comprehensive results analysis supports our initial hypothesis: permanent hard outlier removal is not always what model benefits the most from.

While the global photometry and spatially-resolved outskirts of MRG-S0851 imply an early-formation scenario with a slowly decreasing or constant star-formation history, a joint fit of 2D grism spectroscopy and photometry reveals a more complex scenario: MRG-S0851 is likely to be experiencing a centrally-concentrated rejuvenation in the inner $\sim$1 kpc in the last $\sim$100 Myr of evolution. We estimate $0.5\pm0.1\%$ of the total stellar mass is formed in this phase. Rejuvenation episodes are suggested to be infrequent for massive galaxies at $z\sim2$, but as our analyses indicate, more examples of complex star-formation histories may yet be hidden within existing data. By adding a FUV color criterion to the standard U-V/V-J diagnostic, thereby heightening our sensitivity to recent star formation, we show that we can select populations of galaxies with similar spectral energy distributions to that of MRG-S0851, but note that deep follow-up spectroscopic observations and/or spatially resolved analyses are necessary to robustly confirm the rejuvenation of these candidates. Using our criteria with MRG-S0851 as a prototype, we estimate that $\sim$1\% of massive quiescent galaxies at $1

Variability of the magnetosphere-ionosphere coupling as described by the HAO high-latitude empirical model
Creators: name: Edwin, Stanley

Publisher: name: University Corporation For Atmospheric Research (UCAR)
Year: 2012

Understanding magnetosphere-ionosphere coupling is important because energy transfer from the magnetosphere to the ionosphere needs to be represented. This work examines the High Altitude Observatory (HAO)'s high latitude empirical model that represents magnetosphere-ionosphere coupling as energy transfer between the magnetosphere and the ionosphere. The model represents the spatial distribution of the height integrated Poynting flux, the electric potential and the magnetic potential in the upper atmosphere under varying geophysical conditions. HAO's empirical model was contrasted against Weimer's 2005 empirical model. Both models are derived from the Dynamic Explorer Two (DE-2) data set from August 1981 to March 1983. The purpose of the research was to show that the energy transfer generally quantified by the Joule heating could be estimated by the height integrated Poynting flux. The Poynting flux can be calculated from satellite measurements, while the Joule heating requires knowing the Pederson conductivity, which is not measured by DE-2. This study showed that the Poynting flux can represent the energy transfer in Joule heating by the Poynting flux. Though both models are derived from the same data set, their respective electrical potential has been statistically computed by different methods. Weimer's derived electrical potential from the DE-2 data set has, in general, a greater electrical potential than HAO's derived electrical potential. Weimer's model uses the interplanetary magnetic field (IMF) solar wind velocity and density as extra inputs in comparison to HAO's model. The integrated Poynting flux of HAO's model is comparable with the total Joule heating over a given area. This demonstrates that energy transfer between the magnetosphere and ionosphere can be successfully estimated from satellite measurements, using the integrated Poynting flux.

description: Antifreeze protein is a class of protein which bind ice crystals and thus inhibit recrystalization of ice, and which can be found in animals that live in subzero environments. AFPs are shown to decrease freezing temperature around tissues and therefore enable an improved capacity of Cryopreservation of this tissues. In this paper we suggest a method to increase the thermal hysteresis of AFP-III in order to maintain a lower freezing temperature than once observed. This aim might be achieved by modifications of four amino acids (Ala16, Thr18, Val20 and Gln44) of the protein.

One of the challenges of tropical cyclone prediction is the lack of observations over the ocean. One powerful new source of data is the global positioning system (GPS) radio occultation (RO), which can provide valuable information about the moisture distribution over the ocean. In this study we assessed the impact of GPS RO on the prediction of heavy rainfall associated with Typhoon Morakot (2009), a category two typhoon, which made landfall on Taiwan and caused a huge amount of damage. Two sets of ensemble forecasts were performed using the Weather Research and Forecasting (WRF) model, one with the assimilation of GPS RO data and the other without. The WRF model used triple nests, with grid sizes of 45, 15 and 5 km. The forecasts started at 0000 UTC 6 August 2009, and extended for four days. Our study focused on the third day, the day with maximum rainfall, as well as the four-day total precipitation. Several verification scores were used to evaluate the precipitation forecast skill from the two sets of ensemble forecasts. The verification scores used to compare the two sets of forecasts included: the frequency bias score, the threat score, the Gilbert skill score, the fraction skill score, and image warping. Results from all four of the scores and the image warping indicated that the assimilation of GPS RO data improved the prediction of precipitation, especially the heaviest precipitation. This study used a new method, image warping, which we believe contributes important information for the verification of high resolution forecasts.

description: We propose a rationale for experimentally studying the intricate relationship between the rate of information transmission and synchronization level in active networks, applying theoretical results recently proposed. We consider two non-identical coupled Chua's circuit with non-identical coupling strengths in order to illustrate the proceeding for experimental scenarios of very few data points coming from highly non-coherent coupled systems, such that phase synchronization can only be detected by methods that do not rely explicitely on the calculation of the phase. A relevant finding is to show that for the coupled Chua's circuit, the larger the level of synchronization the larger the rate of information exchanged between both circuits. We further validate our findings with data from numerical simulations, and discuss an extension to arbitrarily large active networks.

description: We examine the cosmological and astrophysical signatures of a "dark baryon," a neutral fermion that mixes with the neutron. As the mixing is through a higher-dimensional operator at the quark level, production of the dark baryon at high energies is enhanced so that its abundance in the early universe may be significant. Treating its initial abundance as a free parameter, we derive new, powerful limits on the properties of the dark baryon. Primordial nucleosynthesis and the cosmic microwave background provide strong constraints due to the inter-conversion of neutrons to dark baryons through their induced transition dipole, and due to late decays of the dark baryon. Additionally, neutrons in a neutron star could decay slowly to dark baryons, providing a novel source of heat that is constrained by measurements of pulsar temperatures. Taking all the constraints into account, we identify parameter space where the dark baryon can be a viable dark matter candidate and discuss promising avenues for probing it.

description: Over the last two decades, the Black Sea region developed to be a key global exporting region for corn and wheat. However, many market participants grapple with insufficient knowledge of factors that drive Black Sea spot prices, while effective futures markets that could facilitate price discovery and risk management are still missing. In our study, we identify marketspecific drivers of volatility of Ukrainian corn and Russian wheat prices. We use daily Black Sea spot price indices for both grains to estimate non-parametric realized volatility measures. These are regressed on several potential drivers, namely, respective futures prices, exchange rates, oil prices and freight rates that serve as a proxy for demand shifts. Estimation results suggest that Ukrainian corn price volatility is well explained by futures price movements and demand shifts, while Russian wheat markets are rather isolated from futures price movements and mostly depend on own lagged volatility and exchange rate movements. Additionally, we find asymmetric responses to price movements at the CBoT: both Black Sea markets react significantly stronger to price increases at the CBoT than to price decreases.

description: The Two Higgs Doublet Model (2HDM) with spontaneously broken $Z_2$ symmetry predicts a production of domain walls at the electroweak scale. We derive cosmological constraints on model parameters for both Type-I and Type-II 2HDMs from the requirement that domain walls do not dominate the Universe by the present day. For Type-I 2HDMs, we deduce the lower bound on the key parameter $\tanβ> 10^5$ for a wide range of Higgs-boson masses $\sim$ 100 GeV or greater close to the Standard Model alignment limit. In addition, we perform numerical simulations of the 2HDM with an approximate as well as an exact $Z_2$ symmetry but biased initial conditions. In both cases, we find that domain wall networks are unstable and, hence, do not survive at late times. The domain walls experience an exponential suppression of scaling in these models which can help ameliorate the stringent constraints found in the case of an exact discrete symmetry. For a 2HDM with softly-broken $Z_2$ symmetry, we relate the size of this exponential suppression to the soft-breaking bilinear parameter $m_{12}$ allowing limits to be placed on this parameter of order $μ$eV, such that domain wall domination can be avoided. In particular, for Type-II 2HDMs, we obtain a corresponding lower limit on the CP-odd phase $θ$ generated by QCD instantons, $θ\ \stackrel{>}{{}_\sim}\ 10^{-11}/(\sinβ\cosβ)$, which is in some tension with the upper limit of $θ\ \stackrel{

The Colorado Coarse Rural Urban Sources and Health (CCRUSH) study is a three-year study focused on characterizing the mass, composition and sources of coarse particulate matter (PM10-2.5) in urban and rural Colorado and evaluating how differences may be associated with several health outcomes. As part of this study, ambient air samples were collected every sixth day for twenty-four hours from four sites in Denver and Greeley, Colorado from February 2010 to March 2011 to study the chemical composition of PM10-2.5. The two sites in Denver were Alsup and Edison Elementary Schools. Edison is an urban-residential site located west of downtown Denver while Alsup is an industrial-residential site. The two sites in Greeley were McAuliffe and Maplewood Elementary Schools. Both are residential sites. Greeley is the county seat of Coloradoâs most prolific agricultural region. Ambient air samples were collected on Teflon filters at each of these locations using a dichotomous filter sampler. Multiple filter samples for each site, usually from the same month, were combined and analyzed for 49 elements in each size (PM2.5 and PM10-2.5). The monthly composites were analyzed by Magnetic Sector Inductively Coupled Plasma-Mass Spectroscopy (SF-ICP-MS). Crustal enrichment factors (CEF) were calculated to assess the contributions of human and natural sources of trace elements on PM10-2.5 emissions. Copper was the most enriched element in all the air samples and Edison was the most enriched in copper of all the sites.
A balancing act : the canonization of Tomson Highway
Creators: name: Covert, Jennifer Lee

description: In this thesis I will examine the critical and popular success of playwright Tomson Highway. Highway's two published plays, "The Rez Sisters" and "Dry Lips Oughta Move to Kapuskasing", are taught on university and high school syllabi across the country and abroad, as far away as Copenhagen. These two plays have also been performed in Canada virtually from coast to coast. These facts are interesting in and of themselves, but specifically when taken into account with the fact that Highway is a Cree playwright, born in northern Manitoba, who didn't become fluent in English until reaching his teens. Moreover, Highway is the only native playwright to have achieved this level of wide-spread acclaim. In this thesis I will examine how and why this phenomenon came about and posit some hypotheses to help to explain it. I will take three steps in dealing with the sudden rise in popularity of Highway's work. In Chapter One I will trace the roots of his success through a selective production history of his two published plays across the country. It will also be important in this chapter to give a brief personal history of the playwright as this will prove an integral reference point. In the second Chapter I will firmly situate Highway within the Canadian dramatic canon, such as it is, through an investigation into where and in which contexts Highway's plays are taught and where they are currently being produced in Canada and abroad. In the final Chapter I will provide some reasons that may account for his success and his rapid canonization. In the conclusion I will discuss the ramifications of his canonization and some of the larger implications of his rapid rise to fame.

description: We study Nahm transformation for parabolic Higgs bundles on the projective line \PP^1, with logarithmic singularities on a finite set P. Such a Higgs bundle can be given by its spectral data: a Hirzebruch surface Z together with a coherent sheaf M on Z, supported in dimension 1 and away from infinity. We describe the transform in terms of these data. The main technical tool is the notion of proper transform of a coherent sheaf with respect to a blow-up. Finally, we prove the main properties of the induced map on moduli spaces: involutibility and preservation of the hyper-Kaehler structure.

Measurement-Induced Quantum Synchronization and Multiplexing

description: Measurements are able to fundamentally affect quantum dynamics. We here show that a continuously measured quantum many-body system can undergo a spontaneous transition from asynchronous stochastic dynamics to noise-free stable synchronization at the level of single trajectories. We formulate general criteria for this quantum phenomenon to occur, and demonstrate that the number of synchronized realizations can be controlled from none to all. We additionally find that ergodicity is typically broken, since time and ensemble averages may exhibit radically different synchronization behavior. We further introduce a quantum type of multiplexing that involves individual trajectories with distinct synchronization frequencies. Measurement-induced synchronization appears as a genuine nonclassical form of synchrony that exploits quantum superpositions.
Rich-club vs rich-multipolarization phenomena in weighted networks

description: Large scale hierarchies characterize complex networks in different domains. Elements at their top, usually the most central or influential, may show multipolarization or tend to club forming tightly interconnected communities. The rich-club phenomenon quantified this tendency based on unweighted network representations. Here, we define this metric for weighted networks and discuss the appropriate normalization which preserves nodes' strengths and discounts structural strength-strength correlations if present. We find that in some real networks the results given by the weighted rich-club coefficient can be in sharp contrast to the ones in the unweighted approach. We also discuss that the scanning of the weighted subgraphs formed by the high-strength hubs is able to unveil features contrary to the average: the formation of local alliances in rich-multipolarized environments, or a lack of cohesion even in the presence of rich-club ordering. Beyond structure, this analysis matters for understanding correctly functionalities and dynamical processes relying on hub interconnectedness.

Understanding the Suns processes and how they affect the Earth allows us to better understand climate change, main sequence stars, and aids in the understanding and prediction of space weather. The need for accurate space weather forecasting increases as our dependence on satellite communication and electric power grids grows. This work examines magnetospheric and ionospheric response to solar wind drivers during solar cycles 23 and 24 (years 2002 through 2010). To date, no studies on Sun-Earth coupling during this period have considered both ionospheric and magnetospheric response to various solar drivers. In this study several satellite data sets were used to examine solar parameters, relativistic and energetic electrons, nitric oxide (NO) infrared radiation and auroral power (Ap). Yearly time series, correlations, and trends in periodicities were examined for the entire period. Active years (2002 and 2003) and inactive years (2008 and 2009) were contrasted in attempts to develop an understanding of the underlying physical processes and relationships among solar, magnetospheric, and ionospheric parameters. Relativistic and energetic particles had the highest correlation with solar wind speed in general, especially during the extended solar minimum when high speed streams (HSS) were present (2008). Periodicity analysis showed dominance of the 27-day solar rotational period for the declining phase of cycle 23, and more prominent 7, 9 and 13.5-day periodicities for the solar minimum. These findings support previous work, and combine two areas of research to reveal a more complete view of Sun-Earth dynamics over this time period.

description: We study the Lebwohl-Lasher model for systems in which spin are arranged on random graph lattices. At equilibrium our analysis follows the theory of spin-systems on random graphs which allows us to derive exact bifurcation conditions for the phase diagram. We also study the dynamics of this model using a variant of the dynamical replica theory. Our results are tested against simulations.

description: Having in view some applications in nanophysics, in particular in nanophysics of materials, we develop new dynamical models of structured bodies with affine internal degrees of freedom. In particular, we construct some models where not only kinematics but also dynamics of systems of affine bodies is affinely invariant. Quantization schemes are developed. This is necessary in the range of physical phenomena we are interested in.
An examination of the link between decadal changes in precipitation, winds, and sea surface heights in the Tropical Indo-Pacific during the period 1993-2010

Climate change has contributed to global sea level rise. However, in situ measurements and satellite observations indicate that this increase is not uniform over the tropical Indo-Pacific basin. Furthermore, satellite altimetry data documented large-scale decadal variations in sea level over much of the tropical Indo-Pacific basin, such that sea level trends underwent a decadal change around 1999/2000. Large-scale reversals in sea level trends are associated with fluctuations in the Indo-Pacific branch of the Walker cell. This research examined the nature of decadal sea level change over the tropical Indo-Pacific basin and how these changes relate to low frequency variations in the strength of the Walker circulation. Understanding the causes of decadal sea level variability will aid in adaptation. The relationship between the decadal changes of sea surface heights and zonal wind stress was investigated for 1993-1999 and for 2000-2010 in three regions showing distinct decadal phase reversals near 1999/2000. Changes in the large-scale circulation associated with the Walker circulation were inferred from decadal changes in the precipitation over the Indo-Pacific warm pool and changes in the zonal winds in both the tropical Pacific and Indian Oceans. To isolate the decadal variability in the three variables, five year centralized running means were used. The results showed a decadal change in the strength of the Walker circulation and a strong correlation to winds and sea levels in the tropical Indian and western Pacific. Variability in the western Pacific and Indian Ocean appeared to be strongly influenced by ENSO.

Southern Terrebonne parish is home to a community of people that live off of the land and water that shares a unique connection to their environment. Unfortunately, the loss of their land due to land dynamics such as subsidence, sea level rise and salt-water intrusion is seldom recognized outside the state of Louisiana. If no action is taken to counter the current trend in wetland loss, communities would lose about a football-size piece of land every hour – a pace that is currently being exceeded. The phone application Vanishing Points concept was developed to broaden the awareness of coastal land loss in this area. This study describes merging physical and social science through the use of Participatory Action Research (PAR) methods used to 1) identify the ‘Vanishing Points’ - locations of cultural, personal, and historical importance as chosen by the community members, 2) determine the history and importance of these locations, 3) record personal testimonies, and 4) collect family historical pictures portraying changes both in land and use. Our study also involves creating animations of historical land loss for each location which will be incorporated in the application. Vanishing Points will bring community and national attention to the impacts of coastal and wetland loss, and encourage advocacy for the protection of the land and - culture of Southern Terrebonne parish.
Peeking Between the Pulses: The Far-UV Spectrum of the Previously Unseen White Dwarf in AR Scorpii

description: The compact object in the interacting binary AR Sco has widely been presumed to be a rapidly rotating, magnetized white dwarf (WD), but it has never been detected directly. Isolating its spectrum has proven difficult because the spin-down of the WD generates pulsed synchrotron radiation that far outshines the WD's photosphere. As a result, a previous study of AR Sco was unable to detect the WD in the averaged far-ultraviolet spectrum from a Hubble Space Telescope (HST) observation. In an effort to unveil the WD's spectrum, we reanalyze these HST observations by calculating the average spectrum in the troughs between synchrotron pulses. We identify weak spectral features from the previously unseen WD and estimate its surface temperature to be 11500$\pm$500K. Additionally, during the synchrotron pulses, we detect broad Lyman-$α$ absorption consistent with hot WD spectral models. We infer the presence of a pair of hotspots, with temperatures between 23000K and 28000K, near the magnetic poles of the WD. As the WD is not expected to be accreting from its companion, we describe two possible mechanisms for heating the magnetic poles. The Lyman-$α$ absorption of the hotspots appears relatively undistorted by Zeeman splitting, constraining the WD's field strength to be 100 MG, but the data are insufficient to search for the subtle Zeeman splits expected at lower field strengths.
