description: We have studied magnetically frustrated Tb$_2$Sn$_2$O$_7$ by neutron diffraction and high resolution energy-resolved neutron scattering. At 0.1 K, we observe short range magnetic correlations with a typical scale of 4 Å, close to the near neighbor distance between Tb$^{3+}$ ions. %(3.686 Å), This short range order coexists with ferromagnetic correlations and long range spin ice order at the scales of 18 and 190 Å, respectively. Spin dynamics was investigated at a time scale down to 10$^{-9}$s, by energy-resolved experiments on a backscattering spectrometer. We observe a freezing of the spin dynamics for all length-scales, with a strong slowing down of the spin fluctuations when long range order settles in. We discuss the spin fluctuations remaining in the ground state in comparison with previous data obtained by muon spectroscopy.

description: We analyze the diffraction characteristics of dielectric gratings that feature a high index grating layer, and devise, through rigorous numerical calculations, large bandwidth, highly efficient, high dispersion dielectric gratings in reflection, transmission, and immersed transmission geometry. A dielectric TIR grating is suggested, whose -1dB spectral bandwidth is doubled as compared to its all-glass equivalent. The short wavelength diffraction efficiency is additionally improved by allowing for slanted lamella. The grating surpasses a blazed gold grating over the full octave. An immersed transmission grating is devised, whose -1dB bandwidth is tripled as compared to its all-glass equivalent, and that surpasses an equivalent classical transmission grating over nearly the full octave. A transmission grating in the classical scattering geometry is suggested, that features a buried high index layer. This grating provides effectively 100% diffraction efficiency at its design wavelegth, and surpasses an equivalent fused silica grating over the full octave.

description: We extract void catalogs from the Sloan Digital Sky Survey Data Release 16 (SDSS DR16) survey and also from the Millennium simulation. We focus our comparison on distribution of galaxies brighter than $M_r < -18$ inside voids and study the mean separation of void galaxies, distance from the void center, and the radial density profile. We find that mean separation of void galaxies depends on void size, as bigger voids have lower mean separation in both samples. However, void galaxies in the observation sample seem to have generally larger mean-distance than simulated ones at any given void size. In addition, observed void galaxies tend to reside closer to the void center than those in the simulation. This discrepancy is also shown in the density profile of voids. Regardless of the void size, the central densities of real void profiles are higher than the ones in the predicted simulated catalog.

description: We complete the details of a theory outlined by Kontsevich and Soibelman that associates to a semi-algebraic set a certain graded commutative differential algebra of "semi-algebraic differential forms" in a functorial way. This algebra encodes the real homotopy type of the semi-algebraic set in the spirit of the DeRham algebra of differential forms on a smooth manifold. Its development is needed for Kontsevich's proof of the formality of the little cubes operad.

Polarization signatures of the head-on collision model for Type Ia supernovae: How much asymmetry is too much?

description: In a previous paper, we showed that the asymmetric ejecta produced by (zero impact parameter) head-on collisions of carbon-oxygen white dwarfs allow these progenitor models for Type Ia supernovae (SNe Ia) to cover the observed two-dimensional (2D) distribution of Si II line depths (Branch plot). In this paper, we study the polarization signature associated with the 2D asymmetric ejecta of the collision model and a double-detonation model using similar TARDIS radiative transfer simulations along different lines of sight with a spherical photosphere, combined with a new 3D Monte Carlo polarization code. We show that the polarization $Q$ can be parametrized as a product $Q=Q_{\max}Q_{\rm{x}}$ of a radial structure component $Q_{\max}$ which is insensitive to the model specifics and is shown to be universally around $Q_{\max}\sim 5\%$, and a cancellation component $Q_{\rm{x}}$ which depends on the asymmetry details. The continuum polarization is found to be low for both the collision and double-detonation models with $Q\sim 0.5\%$. However, the irregular Si distribution in the 2D head-on collision model results in Si II line polarization reaching $Q\sim 3\%$ ($Q_{\rm{x}} \lesssim 50\%$) in tension with observations (mostly $\lesssim 1.2\%$). In contrast, we show that the double-detonation model also covers the Branch plot, and yet results in low line polarization $Q\lesssim 0.7\%$ ($Q_{\rm{x}} \sim 10\%$) consistent with previous results and most SNe Ia. These results strengthen the case for asymmetric explosions as progenitors of SNe Ia, emphasizing an additional requirement for large polarization cancellations to account for the low observed line polarizations.

description: 8. Prodoxidae – prodoxid moths Small (10–28 mm wingspan) moths with a scaled proboscis and similarly shaped forewings and hindwings that are held tentlike over the body when at rest. Females have piercing ovipositors. Th is group includes the yucca moths, which have a wellstudied interdependent relationship with yucca plants. All larvae are concealed feeders in seeds, stems, and (in one species) leaves. The larva of one European species is known to induce galls in which it feeds. Approximately 85 species of Prodoxidae are known, mostly from the Nearctic. Sixteen species are reported from AB. Most groups in the Prodoxidae have been revised recently (Davis 1967; Davis et al. 1992; Pellmyr 1999; Pellmyr et al. 2005), but the genus Lampronia is in need of modern revision.

Optimisation of spatially varying orthotropic porous structures based on conformal mapping

description: In this article, a compliance minimisation scheme for designing spatially varying orthotropic porous structures is proposed. With the utilisation of conformal mapping, the porous structures here can be generated by two controlling field variables, the (logarithm of) the local scaling factor and the rotational angle of the matrix cell, and they are interrelated through the Cauchy-Riemann equations. Thus the design variables are simply reduced to the logarithm values of the local scaling factor on selected boundary points. Other attractive features shown by the present method are summarised as follows. Firstly, with the condition of total differential automatically met by the two controlling field variables, the integrability problem which necessitates post-processing treatments in many other similar methods can be resolved naturally. Secondly, according to the maximum principle for harmonic functions, the minimum feature size can be explicitly monitored during optimisation. Thirdly, the rotational symmetry possessed by the matrix cell can be fully exploited in the context of conformal mapping, and the computational cost for solving the cell problems for the homogenised elasticity tensor is maximally abased. In particular, when the design domain takes a rectangle shape, analytical expressions for the controlling fields are available. The homogenised results are shown, both theoretically and numerically, to converge to the corresponding fine-scale results, and the effectiveness of the proposed work is further demonstrated with more numerical examples.

description: Over the past decades, rest-frame ultraviolet (UV) observations have provided large samples of UV luminous galaxies at redshift (z) greater than 6, during the so-called epoch of reionization. While a few of these UV identified galaxies revealed significant dust reservoirs, very heavily dust-obscured sources at these early times have remained elusive. They are limited to a rare population of extreme starburst galaxies, and companions of rare quasars. These studies conclude that the contribution of dust-obscured galaxies to the cosmic star formation rate density at $z>6$ is sub-dominant. Recent ALMA and Spitzer observations have identified a more abundant, less extreme population of obscured galaxies at $z=3-6$. However, this population has not been confirmed in the reionization epoch so far. Here, we report the discovery of two dust-obscured star forming galaxies at $z=6.6813\pm0.0005$ and $z=7.3521\pm0.0005$. These objects are not detected in existing rest-frame UV data, and were only discovered through their far-infrared [CII] lines and dust continuum emission as companions to typical UV-luminous galaxies at the same redshift. The two galaxies exhibit lower infrared luminosities and star-formation rates than extreme starbursts, in line with typical star-forming galaxies at $z\sim7$. This population of heavily dust-obscured galaxies appears to contribute 10-25 per cent to the $z>6$ cosmic star formation rate density.

Closed-form H-infinity Optimal Control for a Class of Infinite-Dimensional Systems

description: H-infinity optimal control and estimation are addressed for a class of systems governed by partial differential equations with bounded input and output operators. Diffusion equations are an important example in this class. Explicit formulas for the optimal state feedback controller as well as the optimal state estimator are given. Unlike traditional methods for H-infinity synthesis, no iteration is needed to obtain the optimal solution. Moreover, the optimal performance for both the state feedback and state estimation problems are explicitly calculated. This is shown to be useful for problems of H-infinity optimal actuator and sensor location. Furthermore, the results can be used in testing and bench-marking of general purpose algorithms for H-infinity synthesis. The results also apply to finite-dimensional systems.

description: We consider a three-terminal system consisting of a quantum dot strongly coupled to two superconducting reservoirs in the infinite gap limit and weakly coupled to a normal metal. Using a real-time diagrammatic approach, we calculate the dynamics of the proximity-induced pair amplitude on the quantum dot. We find that after a quench the pair amplitude shows pronounced oscillations with a frequency determined by the coupling to the superconductors. In addition, it decays exponentially on a time scale set by the coupling to the normal metal. Strong oscillations of the pair amplitude occur also when the system is periodically driven both in the adiabatic and fast-driving limit. We relate the dynamics of the pair amplitude to the Josephson and Andreev current through the dot to demonstrate that it is an experimentally accessible quantity.

description: Magnetic phenomena are ubiquitous in our surroundings and indispensable for modern science and technology, but it is notoriously difficult to change the magnetic order of a material in a rapid way. However, if a thin nickel film is subjected to ultrashort laser pulses, it can lose its magnetic order almost completely within merely femtosecond times. This phenomenon, in the meantime also observed in many other materials, has connected magnetism with femtosecond optics in an efficient, ultrafast and complex way, offering opportunities for rapid information processing or ultrafast spintronics at frequencies approaching those of light. Consequently, the physics of ultrafast demagnetization is central to modern material research, but a crucial question has remained elusive: If a material loses its magnetization within only femtoseconds, where is the missing angular momentum in such short time? Here we use ultrafast electron diffraction to reveal in nickel an almost instantaneous, long-lasting, non-equilibrium population of anisotropic high-frequency phonons that appear as quickly as the magnetic order is lost. The anisotropy plane is perpendicular to the direction of the initial magnetization and the atomic oscillation amplitude is 2 pm. We explain these observations by means of circularly polarized phonons that quickly absorb the missing angular momentum of the spin system before the slower onset of a macroscopic sample rotation. The time that is needed for demagnetization is related to the time it takes to accelerate the atoms. These results provide an atomistic picture of ultrafast demagnetization under adherence to all conservation laws but also demonstrate the general importance of polarized phonons for non-equilibrium dynamics and provide innovative ways for controlling materials on atomic dimensions.

description: Wilson disease (hepatolenticular degeneration) is an autosomal recessive genetic disorder that involves dysregulation of copper metabolism due to mutations. The mutations cause impaired function of the intracellular copper transporter ATP7B. It is found worldwide, with a prevalence of approximately one case in 30,000 live births in most populations. Impaired copper excretion causes a build-up of copper in many organs, such as the liver, cornea, and brain. As a result, the liver is progressively damaged, and this can lead to cirrhosis. The speed of progression is different in each case. People with Wilson disease often also suffer from psychiatric and neurological symptomsIt is important that more research is done to help identify new biomarkers that can be used to cure Wilson Disease and to identify if there are certain genes that increase the likelihood of certain manifestations becoming more severe or appear early. More research could also help us to better understand possible alternative treatment targets. Although the Wilson disease gene has been cloned, the cellular localization of the gene product (ATP7B) has not been fully clarified. Therefore, the precise physiological action of ATP7B is still unknown.

description: We compute the sum over flat surfaces of disc topology with arbitrary number of conical singularities. To that end, we explore and generalize a specific case of the matrix model of dually weighted graphs (DWG) proposed and solved by one of the authors, M. Staudacher and Th. Wynter. Namely, we compute the sum over quadrangulations of the disc with certain boundary conditions, with parameters controlling the number of squares (area), the length of the boundary and the coordination numbers of vertices. The vertices introduce conical defects with angle deficit given by a multiple of $π$, corresponding to positive, zero or negative curvature. Our results interpolate between the well-known 2d quantum gravity solution for the disc with fluctuating 2d metric and the regime of 'almost flat' surfaces with all the negative curvature concentrated on the boundary. We also speculate on possible ways to study the fluctuating 2d geometry with $AdS_2$ background instead of the flat one.

description: We study the thermostatistical fluctuations of a single Delrin monomer on a granular lattice of dimer particles using both experiment and simulation. The goal is to examine the collision frequency, energy injection, and sidewall effects on a single second-layer particle in a bi-layer granular gas experiment. Non-Gaussian velocity statistics are observed for the single particle of the top layer and result from the presence of defects in the first layer. These deviations are not directly due to the presence of the boundary wall, since the form of velocity distributions is quite spatially homogeneous, but are the consequence of the presence of a few mobile defects in the first layer.

description: We investigate interesting symmetry properties verified by the down-converted beams produced in optical parametric amplification with structured light. We show that the Poincaré sphere symmetry, previously demonstrated for first-order spatial modes, translates to a multiple Poincaré sphere structure for higher orders. Each one of these multiple spheres is associated with a two-dimensional subspace defined by a different value of the orbital angular momentum. Therefore, the symmetry verified by first order modes is reproduced independently in each subspace. This effect can be useful for parallel control of independently correlated beams.

description: We introduce a model of interacting Random Walk, whose hopping amplitude depends on the number of walkers/particles on the link. The mesoscopic counterpart of such a microscopic dynamics is a diffusing system whose diffusivity depends on the particle density. A non-equilibrium stationary flux can be induced by suitable boundary conditions, and we show indeed that it is mesoscopically described by a Fourier equation with a density dependent diffusivity. A simple mean-field description predicts a critical diffusivity if the hopping amplitude vanishes for a certain walker density. Actually, we evidence that, even if the density equals this pseudo-critical value, the system does not present any criticality but only a dynamical slowing down. This property is confirmed by the fact that, in spite of interaction, the particle distribution at equilibrium is simply described in terms of a product of Poissonians. For mesoscopic systems with a stationary flux, a very effect of interaction among particles consists in the amplification of fluctuations, which is especially relevant close to the pseudo-critical density. This agrees with analogous results obtained for Ising models, clarifying that larger fluctuations are induced by the dynamical slowing down and not by a genuine criticality. The consistency of this amplification effect with altered coloured noise in time series is also proved.

Higgs-Radion Mixing with Enhanced Di-Photon Signal

description: In the context of warped scenarios in which Standard Model (SM) fields are allowed to propagate in the bulk, we revisit the possible mixing between the IR localized Higgs field and the Radion graviscalar. The phenomenology of the resulting mostly-Higgs field does not suffer important deviations with respect to the case in which all the SM is localized in the IR brane (original Higgs-Radion mixing scenario). On the contrary, the phenomenology of the mostly-Radion field can present important differences with respect to the original scenario. At the LHC, the most striking effect is now the possibility of sizeable Radion decays into photons in a mass range well beyond the ZZ and WW thresholds, not due to dramatically enhanced couplings to photons but to suppressed couplings to massive fields.

description: 11. Tineidae – fungus moths Minute to small (10–18 mm wingspan) moths with yellowish, brownish, or mottled black and white wings. Th ey can usually be recognized by the erect scales on the head, short labial palps with stiff lateral bristles, a poorly developed proboscis without scales at the base, and the resting posture, with the wings held tentlike over the body. Larvae feed on fungi and detritus, often in specialized habitats such as vertebrate nests or fungal fruiting bodies. Several species are pests of stored products or of fabrics made of wool, fur, or feathers. Many species are not attracted to light and are rarely collected. Approximately 3000 species of tineids have been described worldwide. In North America, 116 species are known; 19 species are reported from AB. Th e group is in need of taxonomic work, and many species remain undescribed, including at least one new species found in AB. Many genera have not been placed or have been placed only tentatively to subfamily. Robinson (2003) maintains a website of worldwide nomenclature. Th e only large taxonomic works were published by Dietz (1905) and Forbes (1923). The former treats all but two of the species known or expected to occur in AB, but it is poorly illustrated and out of date nomenclaturally. Other useful works include Davis (1978c) and Robinson (1986). Identification is best done by comparison to authoritatively determined material.

description: We study the time-dependent transport of charge and spin through a ring-shaped region sequentially coupled to a weakly interacting quantum dot in the presence of an Aharonov-Bohm flux and spin-orbit interaction. The time-dependent modulation of the spin-orbit interaction, or of the corresponding Aharonov-Casher flux, together with the modulation of the dot-level induces an electrically pumped spin current even in absence of a charge current. The results beyond the adiabatic regime show that an additional rectification current proportional to \cos(ϕ), being ϕthe relative phase between the time varying parameters, is generated. We discuss the relevance of such term in connection with recent experiments on out-of-equilibrium quantum dots.

Development of a nighttime cooling model for remote sensing thermal inertia mapping
Creators: name: Leckie, Donald Gordon
Publisher: name: University of British Columbia
Year: 2010

description: The capabilities of remote sensing can be utilized to map the thermal inertia of a surface. Thermal inertia is a property governing the temperature response of a medium to a heat flux at its surface and is beneficial to geologic mapping and soils stud ies. It is hypothesized that a method using only nighttime cooling will give a simple thermal inertia model requiring a minimum of input. Albedo and topographic slope and aspect data are not required. Since latent heat flux is commonly small at night the model should be applicable over surfaces of varying moisture content. The objective of this thesis is to develop a nighttime cooling model for remote sensing thermal inertia mapping. Three models (I, II, and III) are presented. They are based on solutions to the one-dimensional heat conduction equation for a semi-infinite homogeneous solid with isothermal initial temperature and time dependent boundary conditions of heat flux at the surface. Tests of the models on several soil types using ground based data indicate that all three models give meaningful relative relationships between thermal inertias and that model III often yields accurate quantitative results. For the remote sensing implementation of the model ground heat flux is determined as the residual of the energy balance of the surface. Thus, a procedure for determining net radiation using remotely sensed temperature is discussed. Also, aerodynamic heat transfer theory is used to develop a remote sensing method of estimating sensible heat flux. Corrections for the surface sublayer are necessary. Results for vegetated surfaces are expected to be unreliable. Latent heat flux is assumed to be zero or the average of several sites. Tests of these methods using ground based data give good results. An error analysis approach is used to estimate the errors resulting from a remote sensing implementation of Model III. Airborne thermal line-scan data and ground based micrometeorological observations are used to determine typical errors in the input parameters of the model. Errors in determining the energy balance components are also analyzed in detail. With good input, model III gives reasonable results (generally less than 50 percent probable error) at low thermal inertias (< 2000 J m⁻² C⁻¹ s⁻[sub ½] ). For surfaces of high thermal inertia, errors are large. The limitation of the model is not in the model itself, but in the accuracy of remotely sensed surface temperature as determined from thermal infrared line-scan surveys. For surfaces of low thermal inertia model III provides a simple thermal inertia mapping method which requires a minimum of input and is applicable over a wide variety of terrain and ground moisture conditions. The model is most suitable for the investigation of soils and may provide a useful model for planetary studies.
