description: We present initial results from the Wide-field Infrared Survey Explorer (WISE), a four-band all-sky thermal infrared survey that produces data well suited to measuring the physical properties of asteroids, and the NEOWISE enhancement to the WISE mission allowing for detailed study of Solar system objects. Using a NEATM thermal model fitting routine we compute diameters for over 100,000 Main Belt asteroids from their IR thermal flux, with errors better than 10%. We then incorporate literature values of visible measurements (in the form of the H absolute magnitude) to determine albedos. Using these data we investigate the albedo and diameter distributions of the Main Belt. As observed previously, we find a change in the average albedo when comparing the inner, middle, and outer portions of the Main Belt. We also confirm that the albedo distribution of each region is strongly bimodal. We observe groupings of objects with similar albedos in regions of the Main Belt associated with dynamical breakup families. Asteroid families typically show a characteristic albedo for all members, but there are notable exceptions to this. This paper is the first look at the Main Belt asteroids in the WISE data, and only represents the preliminary, observed raw size and albedo distributions for the populations considered. These distributions are subject to survey biases inherent to the NEOWISE dataset and cannot yet be interpreted as describing the true populations; the debiased size and albedo distributions will be the subject of the next paper in this series.

description: The objective of this work was to select a training system suitable for grapevines grown in areas where vine burial is practiced for protection against winter chill (especially as it is practised in the arid/semiarid areas of northern China). We evaluate the inﬂuence of a new training system crawled cordon training (CCT) and compare it with a traditional training system independent long-stem pruning (ILSP). The study considers fruit quality, sensory evaluation of wines and an analysis of labour practices at Rongchen Chateau in China during the years 2011, 2012 and 2013. During the first three years under CCT, average yield was 39.69 % lower than under ILSP but CCT showed higher yield stability. The ripeness of grapes under CCT was higher than under ILSP, so sensory evaluation of CCT wines was also higher. Moreover, CCT also reduced the labour involved for winter pruning, summer pruning and harvesting by 24.4 %, 25.0 % and 37.5 %, respectively. This study shows that under CCT grape quality, yield stability and wine quality were significantly higher than under ILSP, while labour inputs (costs) were significantly lower.

One-point height fluctuations and two-point correlators of $(2+1)$ cylindrical KPZ systems

description: While the 1-point height distributions (HDs) and 2-point covariances of $(2+1)$ KPZ systems have been investigated in several recent works for flat and spherical geometries, for the cylindrical one the HD was analyzed for few models and nothing is known about the spatial and temporal covariances. Here, we report results for these quantities, obtained from extensive numerical simulations of discrete KPZ models, for three different setups yielding cylindrical growth. Beyond demonstrating the universality of the HD and covariances, our results reveal other interesting features of this geometry. For example, the spatial covariances measured along the longitudinal and azimuthal directions are different, with the former being quite similar to the curve for flat $(2+1)$ KPZ systems, while the latter resembles the Airy$_2$ covariance of circular $(1+1)$ KPZ interfaces. We also argue (and present numerical evidence) that, in general, the rescaled temporal covariance $\mathcal{A}(t/t_0)$ decays asymptotically as $\mathcal{A}(x) \sim x^{-\barλ}$ with an exponent $\barλ = β+ d^*/z$, where $d^*$ is the number of interface sides kept fixed during the growth (being $d^* = 1$ for the systems analyzed here). Overall, these results complete the picture of the main statistics for the $(2+1)$ KPZ class.

description: We discuss and solve the transport without transit quantum paradox recently introduced in the context of the adiabatic transport of a single particle or a Bose--Einstein condensate between the two extreme traps of a triple-well potential. To this aim, we address the corresponding quantum dynamics in terms of Bohmian trajectories and show that transport always implies transit through the middle well, in full agreement with the quantum continuity equation. This adiabatic quantum transport presents a very counterintuitive effect: by slowing down the total time duration of the transport process, ultra-high Bohmian velocities are achieved such that, in the limit of perfect adiabaticity, relativistic corrections are needed to properly address the transfer process while avoiding superluminal matter wave propagation.

'Concord' was confirmed to be an offspring of 'Catawba' and another unknown wild parent. Since these two important American varieties most likely resulted from random natural crosses and successful selection, the original, wild growing wild donors remain unknown.

description: Faraday rotation measure synthesis is a method for analyzing multichannel polarized radio emissions, and it has emerged as an important tool in the study of galactic and extra-galactic magnetic fields. The method requires the recovery of the Faraday dispersion function from measurements restricted to limited wavelength ranges, which is an ill-conditioned deconvolution problem. Here, we discuss a recovery method, which assumes a sparse approximation of the Faraday dispersion function in an over-complete dictionary of functions. We discuss the general case, when both thin and thick components are included in the model, and we present the implementation of a greedy deconvolution algorithm. We illustrate the method with several numerical simulations that emphasize the effect of the covered range and sampling resolution in the Faraday depth space, and the effect of noise on the observed data.

description: Leaf removal is a viticultural practice applied to improve cluster microclimate and grape composition. This practice can reduce the incidence of bunch rot but could also promote the degradation of berry methoxypyrazines, key components for the aromatic profile of 'Sauvignon blanc' wines. The influence of cluster-zone leaf removal, applied after berry set, was evaluated on 'Sauvignon blanc' grapevines grown in the Isonzo DOC region (Italy). In 2010 and 2011, yield components and fruit chemical composition were recorded from vines in which the five basal leaves of each single shoot were manually removed at the groat-sized phenological stage, and compared to untreated vines. Our results indicated that leaf removal did not influence yield or fruit composition at harvest, but significantly decreased the incidence and severity of Botrytis bunch rot, while reducing the severity of sunburn damage to the fruit. Increased sunlight cluster exposure decreased 2-methoxy-3-isobutylpyrazine (IBMP) and 3-isopropyl-2-methoxypyrazine (IPMP) concentrations in early stages of berry development, whereas at harvest no significant differences between treatments (defoliated and non-defoliated) were observed. We conclude that leaf removal performed after berry set is a pivotal viticultural management practice to cope with harvest bunch rot complex without negatively affecting fruit composition at harvest.

Combined effect of mutually frequency-detuned strong and weak drives on a two-level system: Envelope of the Rabi oscillations
Creators: name: Raikh, M. E.
Publisher: name: arXiv

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: Near-resonant ac-drive acting on a two-level system induces the Rabi oscillations of the level occupations. It is shown that additional weak drive properly frequency-detuned from the primary drive causes a resonant response. This response manifests itself in the emergence of the envelope of the oscillations. At resonance, the inverse period of the envelope is proportional to the amplitude of the weak drive. The resonant condition reads: difference of frequencies between the two drives is equal to the ac-splitting of quasilevels in the field of the strong drive. Technically, the resonance can be inferred from the analogy between the equations for the time-evolution of the spin amplitude and the Mathieu equation, which describes e.g. the parametric resonance.

Leaf respiration in grapevine (Vitis vinifera 'Chasselas') in relation to environmental and plant factors
Creators: name: Zufferey, V.
Publisher: name: VITIS - Journal of Grapevine Research
Year: 2016

description: The leaf respiration (RD) of grapevine (Vitis vinifera 'Chasselas') was measured under field conditions during the growing season in leaves of different physiological ages in relation to the temperature and plant water status. RD increased with the temperature and was particularly high in young growing leaves on primary and lateral shoots. The RD response to the temperature evolved over the season according to the type and age of the leaves and their phenology. Leaf aging (senescence) induced a decrease in RD at the end of the season. At constant temperatures (20 °C), the highest RD rates were measured during the rapid plant growth phase (the Q10 values were also the highest), and they progressively decreased to reach their lowest rates at the end of the growing season. The lowest RD values were measured on leaves that were inserted opposite the clusters of primary shoots at any period during the season. Water stress led to a reduction in RD, especially when the leaf temperature was above 20 °C. The nocturnal RD evolution showed that the RD rates were greatest at nightfall when the nocturnal temperatures were still high and leaf carbohydrate availability was at its highest; the rates gradually decreased to reach the lowest RD values just before dawn.

Coma environment of comet C/2017 K2 around the water ice sublimation boundary observed with VLT/MUSE

description: We report a new imaging spectroscopic observation of Oort-cloud comet C/2017 K2 (hereafter K2) on its way to perihelion at 2.53 au, around a heliocentric distance where H2O ice begins to play a key role in comet activation. Normalized reflectances over 6 500--8 500 AA for its inner and outer comae are 9.7+/-0.5 and 7.2+/-0.3 % (10^3 AA)^-1, respectively, the latter being consistent with the slope observed when the comet was beyond the orbit of Saturn. The dust coma at the time of observation appears to contain three distinct populations: mm-sized chunks prevailing at <~10^3 km; a 10^5-km steady-state dust envelope; and fresh anti-sunward jet particles. the dust chunks dominate the continuum signal and are distributed over a similar radial distance scale as the coma region with redder dust than nearby. they also appear to be co-spatial with OI1D, suggesting that the chunks may accommodate H2O ice with a fraction (>~1 %) of refractory materials. The jet particles do not colocate with any gas species detected. The outer coma spectrum contains three significant emissions from C2(0,0) Swan band, OI1D, and CN(1,0 red band, with an overall deficiency in NH2. Assuming that all OI1D flux results from H2O dissociation, we compute an upper limit on the water production rate Q_H2O of ~7 x 10^28 molec s^-1 (with an uncertainty of a factor of two). the production ratio log[Q_C2/Q_CN] of K2 suggests that the comet has typical carbon-chain composition, with the value potentially changing with distance from the Sun. Our observations suggest that water ice-containing dust chunks (>0.1 mm) near K2's nucleus emitted beyond 4 au may be responsible for its very low gas rotational temperature and the discrepancy between its optical and infrared lights reported at similar heliocentric distances.

description: In this paper we study the $ K $-theory of free quantum groups in the sense of Wang and Van Daele, more precisely, of free products of free unitary and free orthogonal quantum groups. We show that these quantum groups are $ K $-amenable and establish an analogue of the Pimsner-Voiculescu exact sequence. As a consequence, we obtain in particular an explicit computation of the $ K $-theory of free quantum groups. Our approach relies on a generalization of methods from the Baum-Connes conjecture to the framework of discrete quantum groups. This is based on the categorical reformulation of the Baum-Connes conjecture developed by Meyer and Nest. As a main result we show that free quantum groups have a $ γ$-element and that $ γ= 1 $. As an important ingredient in the proof we adapt the Dirac-dual Dirac method for groups acting on trees to the quantum case. We use this to extend some permanence properties of the Baum-Connes conjecture to our setting.

Context and teacher practice : visual art in a secondary traditional school
Creators: name: Boulton-Funke, Adrienne
Publisher: name: University of British Columbia
Year: 2009

description: Based on a ten-week case study in a senior Visual Art class, at The Secondary Traditional School in Lower Mainland British Columbia, this thesis identifies how the traditional educational philosophy conditioned the curriculum decisions and pedagogical practices of a Visual Art teacher. Data was collected from three groups of participants: the Principal of the school, the Visual Art teacher, and a focus group of Visual Art students using the ethnographic methods of document collection, participant observation, and formal and informal interviews. Analysis of the characteristics of Goodlad et al’s (1979) five domains of curriculum: official, perceived, ideal, operationalized, and experienced indicated that recent reforms to education, reflecting neoliberal policy, significantly shaped the experience of teaching and learning in Visual Art in the traditional public school. Legislated neoliberal reforms to education, legitimized schools-of-choice in the province allowing for the propagation of traditional schools by individuals well versed in the idioms of choice. The traditional philosophy’s back-to-basics curriculum and teacher-centered pedagogical approach, coupled with visual acts of symbolic respect created a learning environment, which challenged the implementation of Visual Art curriculum and pedagogical practices that emphasized critical thinking and contemporary conceptual art practice. The discursive practices of the official curricula constructed the student as transitioning from child to young adult. The official role of those in the school community was to enforce the values of the home and parents during this suspended state of transition. To do so the school culture reformed the typical autonomous activity of teaching in a Visual Art class into a distributed process by conforming teacher practice to the official philosophy. The ways in which student ‘lifers’ of traditional schooling experienced the operationalized and ideal curriculum directed the curriculum and pedagogical practices of the teacher. Critical thinking and social responsibility emphasized in the perceived curriculum were passively resisted by student participants performing the visual acts of respect and integrity perpetuated by the Key Visuals and Ten Tenets of traditional schooling. These acts served to redirect teacher practice to maintain the aims of the teacher through pedagogical practices and curriculum design that closely mirrored the teacher-centered approach.

description: Xylotrechus arvicola is a pest in vineyards on the Iberian Peninsula. The action of the larvae, associated to the spread of wood fungi, causes a direct and indirect damage in the crop. This article presents biometric traits of X. arvicola population adults captured in three grape fields with Protected Designation of Origin (PDO) from the Iberian Peninsula and one population of this beetle obtained in the laboratory. The aim of the study was to observe the influence of sex and environment on the size of adults. The adults showed intersexual differences for the length and width of the pronotum, the length and width of the elytra and total length. The wild females were larger than wild males and the males from grape fields were slender than wild females. The environment affected the size of the adults. The laboratory adults reached the greatest body size. The size of the adult reflects the volume of material that had been used as host where the insect had developed. The captured adults in PDO Toro, with Bush Vines Training System (BVTS) were larger than the other PDOs, leading to bigger galleries and exit holes, which could affect the structural resistance of the plant and increase pathogenic fungi infection. However, BVTS facilitates the renovation of attacked branches, which is more difficult and slower in the Bilateral Cordon Training System (BCTS).

What Sets the Initial Rotation Rates of Massive Stars?

description: The physical mechanisms that set the initial rotation rates in massive stars are a crucial unknown in current star formation theory. Observations of young, massive stars provide evidence that they form in a similar fashion to their low-mass counterparts. The magnetic coupling between a star and its accretion disk may be sufficient to spin down low-mass pre-main sequence (PMS) stars to well below breakup at the end stage of their formation when the accretion rate is low. However, we show that these magnetic torques are insufficient to spin down massive PMS stars due to their short formation times and high accretion rates. We develop a model for the angular momentum evolution of stars over a wide range in mass, considering both magnetic and gravitational torques. We find that magnetic torques are unable to spin down either low or high mass stars during the main accretion phase, and that massive stars cannot be spun down significantly by magnetic torques during the end stage of their formation either. Spin-down occurs only if massive stars' disk lifetimes are substantially longer or their magnetic fields are much stronger than current observations suggest.

description: In recent years, digital twins have been proposed and implemented in various fields with potential applications ranging from prototyping to maintenance. Going forward, they are to enable numerous efficient and sustainable technologies, among them autonomous cars. However, despite a large body of research in many fields, academics have yet to agree on what exactly a digital twin is -- and as a result, what its capabilities and limitations might be. To further our understanding, we explore the capabilities of digital twins concerning diagnosis in the field of transportation. We conduct a systematic mapping study including digital twins of vehicles and their components, as well as transportation infrastructure. We discovered that few papers on digital twins describe any diagnostic process. Furthermore, most existing approaches appear limited to system monitoring or fault detection. These findings suggest that we need more research for diagnostic reasoning utilizing digital twins.

We demonstrate the feasibility of direct ALD growth with trimethylaluminum(TMA) and water as precursors on both 2D crystals. Through theoretical and experimental studies, we found that the initial ALD cycles play the critical role, during which physical adsorption dominates precursor adsorption at the semiconductor surface. We model the initial ALD growth stages at the 2D surface by analyzing Lennard-Jones Potentials, which could guide future optimization of the ALD process on 2D crystals.

QTL mapping revealed a major resistance locus on chromosome 5 that explained up to 17.4 % of the phenotypic variance. This new resistance locus was named Rpv14. It was transmitted from the male grandparent V. cinerea Arnold to 'Börner' and is associated with the marker GF05-13.

description: The model for pulsar wind nebulae (PWNe) as the result of the magnetohydrodynamic (MHD) downstream flow from a shocked, relativistic pulsar wind has been successful in reproducing many features of the nebulae observed close to the central pulsars. However, observations of well-studied young nebulae like the Crab Nebula, 3C 58, and G21.5--0.9 do not show the toroidal magnetic field on a larger scale that might be expected in the MHD flow model; in addition, the radial variation of spectral index due to synchrotron losses is smoother than expected in the MHD flow model. We find that pure diffusion models can reproduce the basic data on nebular size and spectral index variation for the Crab, 3C 58, and G21.5--0.9. Most of our models use an energy independent diffusion coefficient; power law variations of the coefficient with energy are degenerate with variation in the input particle energy distribution index in the steady state, transmitting boundary case. Energy dependent diffusion is a possible reason for the smaller diffusion coefficient inferred for the Crab. Monte Carlo simulations of the particle transport allowing for advection and diffusion of particles suggest that diffusion dominates over much of the total nebular volume of the Crab. Advection dominates close to the pulsar and is likely to play a role in the X-ray half-light radius. The source of diffusion and mixing of particles is uncertain, but may be related to the Rayleigh-Taylor instability at the outer boundary of a young PWN or to instabilities in the toroidal magnetic field structure.

Reconciling notions of asylum and refugees in Islam and international law : a case study of Afghan refugees in Pakistan
Creators: name: Nicolson, Vanessa Johan
Publisher: name: University of British Columbia
Year: 2009

description: Muslims constitute the largest refugee populations worldwide. However, a lack of refugee protection mechanisms in the Muslim world (where most Muslims seek asylum) leaves these groups vulnerable to the interests of individual states. At the same time, Muslims face fierce prejudice in the West, including the depiction of Islam as an anti-Western, anti-democratic, and anti-modern religion. However, an examination of Islamic precepts reveals the falsity of such allegations, especially with regard to refugees and asylum. Islam provides a normative framework for socio-economic justice, including asylum, and sets out regulations for the assistance and protection of refugees. In spite of this, little scholarly work has explored the role of Islam in issues of asylum and refugees. This article examines the past three decades of Afghan refugees in Pakistan. It attempts to explain the role of Islam in Pakistan’s initial acceptance of Afghan refugees, and why this generosity eventually transformed into hostility. It also reveals the flaws of UNHCR operations in the Afghan case, from which useful inferences can be drawn to Muslim refugee crises in general. Finally, this thesis outlines challenges and solutions to incorporating Islamic principles into Islamic state responses to Muslim refugee crises. It concludes that stronger multilateral agreements based on Islamic refugee laws should be made between Muslim states (with full UNHCR support) to provide more effective responses to Muslim refugee crises and better protection of Muslim refugees’ rights.

description: Xylotrechus arvicola (Coleoptera: Cerambycidae) is a xylophagous species that is becoming an important pest in vineyards in the Iberian Peninsula. The most sensitive stages are adult and egg, but their neonate larvae can also be attacked during the first 24 h after hatching and before entering the wood. Adults were evaluated for seven days against the insecticides spinosad, Beauveria bassiana, imidacloprid and chlorpyrifos and neonate larvae (< 24 h) and eggs of different ages against the described insecticides, as well as flufenoxuron and pyriproxyfen. All insecticides were applied in a Potter tower at a maximum and minimum commercial dose, and showed significant differences both among insecticides as between the applied doses. Most of the hatching occurs eight days after oviposition by X. arvicola females. Chlorpyrifos had a quick and total control of eggs of different ages, neonate larvae and adults in both dosis applied, but its effectiveness could cause serious effects on other non-target species. Pyriproxifen and flufenoxuron had the best ovicidal control when the age of eggs increases and, B. bassiana also had a good ovicidal control, due its capacity to invade the eggs actively through their shell and proliferate inside them. Biological insecticides such as B. bassiana and spinosad, with a total control on adults and good rates of mortality of neonate larvae and eggs can be a great instrument to biological control of this pest.

description: Shipowners are interested in instrumenting their ship for ice load measurements in order to get a better knowledge about the ice-structure interaction on the ship’s hull. The availability of several full-scale measurements in ice-covered waters is limited which is why future full-scale measurements are scientifically appreciated. The measurement of shear strains on the frame with strain gauges is chosen for the measurement set up. From the shear strains the ice load will be determined with the help of an influence coefficient matrix. In order to determine this load-strain relation of the instrumented section, a finite element analysis of this section will be conducted.

description: Continuous-variable quantum key distribution which can be implemented using only low-cost and off-the-shelf components reveals great potential in the practical large-scale realization. Access network as a modern network necessity, connects multiple end-users to the network backbone. In this work, we demonstrate the first upstream transmission quantum access networks using continuous-variable quantum key distribution. A two-end-user quantum access network is then experimentally realized. Through phase compensation, data synchronization and other technical upgrades, we achieve 390kbps secret key rate of the total network. In addition, we extend the case of two-end-user quantum access network to the case of multiple users, and analyze the network capacity in the case of multiple users by measuring the additive excess noise from different time slots.

Quantum correlations and violation of Bell inequality induced by External Field in a two photon radiative cascade

description: We study the polarization dependent second order correlation of a pair of photons emitted in a four level radiative cascade driven by an external field. It is found that the quantum correlations of the emitted photons, degraded by the energy splitting of the intermediate levels in the radiative cascade can be efficiently revived by a far detuned external field. The physics of this revival is linked to an induced stark shift and the formation of dressed states in the system by the non-resonant external field. Further, we investigated the competition between the effect of the coherent external field and incoherent dephasing of the intermediate levels. We found that the degradation of quantum correlations due to the incoherent dephasing can be content for small dephasing with the external field. We also studied the non-locality of the correlations by evaluating the Bell's inequality in the linear polarization basis for the radiative cascade. We find that the Bell parameter decreases rapidly with increase in the intermediate level energy splitting or incoherent dephasing rate to the extent that there is no violation. However, the presence of an external field leads to control over the degrading mechanisms and preservation of nonlocal correlation among the photons. This in turn can induce, violation of Bell's inequality in the radiative cascade for arbitrary intermediate level splitting and small incoherent dephasing.

description: Bibliography: p. 92-97.
description: In the northern Dogtooth Mountains, the exposed Precambrian rocks are represented by the Horsethief Creek Formation, 700o+ ft. thick, contorted and faulted, consisting of four members in the following upward sequence: Feldspathic Grit Member, Lower Slate Member, Limestone Member, and Upper Shale Member. The Feldspathic Grit Member is interpreted as mainly delta-front elastic deposits and is recognized over the total study area. Available evidence suggests the sediments were derived from the east. The Lower Slate Member is mainly slate, interpreted as marine, with upper parts probably equivalent in age to parts of the Limestone Member. The Limestone Member consists of carbonate and elastic rocks varying from supratidal to probably "deeper" water deposits. Slumped units and close lateral relationship of shallow and "deeper" water deposits suggest minor penecontemporaneous tectonism. The Upper Shale Member is mainly dolomitic elastic rocks, and is recognizable with certainty only in eastern parts of the area. At Rogers Pass, and in areas where metamorphic minerals higher in grade than chlorite occur, identification of the members is hazardous. Locally, garnetiferous rocks occur, but most of the area contains rocks probably representing the biotite zone. The sequence of members is recognizable in homotaxial rocks throughout the southern Canadian Cordillera. Local absence of this sequence may be due to facies changes, and/or erosion at the sub-Cambrian unconformity. The base of the Cambrian Hamill Group is sharply defined in some places and apparently gradational in others.
Determination of Jet Energy Calibration and Transverse Momentum Resolution in CMS

Year: 2011
Subjects: subject: Instrumentation and Detectors (physics.ins-det)

description: Measurements of the jet energy calibration and transverse momentum resolution in CMS are presented, performed with a data sample collected in proton-proton collisions at a centre-of-mass energy of 7 TeV, corresponding to an integrated luminosity of 36 inverse picobarns. The transverse momentum balance in dijet and gamma/Z+jets events is used to measure the jet energy response in the CMS detector, as well as the transverse momentum resolution. The results are presented for three different methods to reconstruct jets: a calorimeter-based approach, the "Jet-Plus-Track" approach, which improves the measurement of calorimeter jets by exploiting the associated tracks, and the "Particle Flow" approach, which attempts to reconstruct individually each particle in the event, prior to the jet clustering, based on information from all relevant subdetectors.

Ab-initio Low-Energy Model of Transition-Metal-Oxide Heterostructure LaAlO3/SrTiO3

description: We develop the multi-scale ab-initio scheme for correlated electrons (MACE) for transitionmetal-oxide heterostructures, and determine the parameters of the low-energy effective model. By separating Ti t2g bands near the Fermi level from the global Kohn-Sham (KS) bands of LaAlO3/SrTiO3 which are highly entangled with each other, we are able to calculate the parameters of the low-energy effective model of the interface with the help of constrained random phase approximation (cRPA). The on-site energies of the Ti t2g orbitals in the 1stlayer is about 650 meV lower than those in the 2nd-layer. In the 1st-layer, the transfer integral of the Ti t2g orbital is nearly the same as that of the bulk SrTiO3, while the effective screened Coulomb interaction becomes about 10 percent larger than that of the bulk SrTiO3. The differences of the parameters from the bulk SrTiO3 reduce rapidly with increasing distance from the interface. Our present versatile method makes it possible to derive effective ab-initio low-energy models and allows studying interfaces of strongly correlated electron systems from first principles.

A hidden population of white dwarfs with atmospheric carbon traces in the Gaia bifurcation

description: The ESA Gaia space mission has revealed a bifurcation of the white dwarf (WD) sequence on the color magnitude diagram in two branches: A and B. While the A branch consists mostly of WDs with H-rich atmospheres, the B branch is not completely understood. Although invoked to be populated mainly by He-rich WDs, the B branch overlaps a $\sim 0.8M_\odot$ evolutionary track with a pure He envelope, fact that would imply an unexpected peak in the WD mass distribution. In cold He-rich WDs, it is expected that the outer convective zone penetrates into deep C-rich layers, thus leading to a slight C contamination in their surfaces at $\sim 10,000$K. Here we aim at studying the Gaia bifurcation as the natural consequence of C dredge-up by convection in cold He-dominated WDs. Relying on accurate atmosphere models, we provide a new set of evolutionary models for He-rich WDs employing different prescriptions for the C enrichment. On the basis of these models, we made a population synthesis study of the Gaia 100pc WD sample to constrain the models that best fit the bifurcation. Our study shows that He-rich WD models with a slight C contamination below the optical detection limit can accurately reproduce the Gaia bifurcation. We refer to these stars as stealth DQ WDs because they do not exhibit detectable C signatures in their optical spectra, but the presence of C in their atmosphere produces a continuum absorption favouring the emission in bluer wavelengths, thereby creating the B branch of the bifurcation. Also, we show that the mass distribution for He-rich WDs obtained when a stealth C contamination is considered is consistent with the mass distribution for H-rich WDs and with the standard evolutionary channels for their formation. We conclude that stealth DQ WDs can account for the lower branch in the Gaia bifurcation. The C signatures of these stars could be detectable in Ultra-Violet spectra.

description: A novel lasing scheme for terahertz quantum cascade lasers, based on consecutive phonon-photon-phonon emissions per module, is proposed and experimentally demonstrated. The charge transport of the proposed structure is modeled using a rate equation formalism. An optimization code based on a genetic algorithm was developed to find a four-well design in the $\mathrm{GaAs/Al_{0.25}Ga_{0.75}As}$ material system that maximizes the product of population inversion and oscillator strength at 150 K. The fabricated devices using Au double-metal waveguides show lasing at 3.2 THz up to 138 K. The electrical characteristics display no sign of differential resistance drop at lasing threshold, which suggests - thanks to the rate equation model - a slow depopulation rate of the lower lasing state, a hypothesis confirmed by non-equilibrium Green's function calculations.
