description: We consider the zero viscosity limit of long time averages of solutions of damped and driven Navier-Stokes equations in ${\mathbb R}^2$. We prove that the rate of dissipation of enstrophy vanishes. Stationary statistical solutions of the damped and driven Navier-Stokes equations converge to renormalized stationary statistical solutions of the damped and driven Euler equations. These solutions obey the enstrophy balance.

description: The Universal Identity Resolution Graph Neural Network is an multidomain, cross-channel algorithmic knowledge graph providing persistent digital identity resolution, created through a unique set of Recurrent Neural Network (RNN) used to deterministically and probabilistically stitch real-time micro-moments information and customer data through a process called “Automated Algorithmic Identity Resolution or AAIR”.

A Universal Identity Resolution Graph Neural Network algorithm connects identities across computing devices and digital channels to one customer. The universal identification allow marketers to engage customers with relevant brand experience as they move between devices and across all digital channels. The universal identification graph algorithm enables mapping of a customer's journey across multiple, different identifications, allows deep personalization based on behaviors, habits, and preferences across the entire customer journey, helps create a more comprehensive customer profile to enable marketers to target the customer with relevant content at the right time and through the right channels, and also provides the customer with the ability to quickly opt out

description: Asteroid phase curves are used to derive fundamental physical properties through the determination of the absolute magnitude H. The upcoming visible Legacy Survey of Space and Time (LSST) and mid-infrared Near-Earth Object Surveillance Mission (NEOSM) surveys rely on these absolute magnitudes to derive the colours and albedos of millions of asteroids. Furthermore, the shape of the phase curves reflects their surface compositions, allowing for conclusions on their taxonomy. We derive asteroid phase curves from dual-band photometry acquired by the Asteroid Terrestrial-impact Last Alert System telescopes. Using Bayesian parameter inference, we retrieve the absolute magnitudes and slope parameters of 127,012 phase curves of 94,777 asteroids in the photometric $H, G_1, G_2$- and $H, G^*_{12}$-systems. The taxonomic complexes of asteroids separate in the observed $G_1, G_2$-distributions, correlating with their mean visual albedo. This allows for differentiating the X-complex into the P-, M-, and E-complexes using the slope parameters as alternative to albedo measurements. Further, taxonomic misclassifications from spectrophotometric datasets as well as interlopers in dynamical families of asteroids reveal themselves in $G_1, G_2$-space. The $H, G^*_{12}$-model applied to the serendipitous observations is unable to resolve target taxonomy. The $G_1, G_2$ phase coefficients show wavelength-dependency for the majority of taxonomic complexes. Serendipitous asteroid observations allow for reliable phase curve determination for a large number of asteroids. To ensure that the acquired absolute magnitudes are suited for colour computations, it is imperative that future surveys densely cover the opposition effects of the phase curves, minimizing the uncertainty on H. The phase curve slope parameters offer an accessible dimension for taxonomic classification.

description: We have carried out a Spitzer survey for brown dwarf (BD) disks in the ~5 Myr old Upper Scorpius (UpSco) star forming region, using IRS spectroscopy from 8 to 12μm and MIPS photometry at 24μm. Our sample consists of 35 confirmed very low mass members of UpSco. Thirteen objects in this sample show clear excess flux at 24μm, explained by dust emission from a circum-sub-stellar disk. Objects without excess emission either have no disks at all or disks with inner opacity holes of at least ~5 AU radii. Our disk frequency of 37\pm 9% is higher than what has been derived previously for K0-M5 stars in the same region (on a 1.8 sigma confidence level), suggesting a mass-dependent disk lifetime in UpSco. The clear distinction between objects with and without disks as well as the lack of transition objects shows that disk dissipation inside 5 AU occurs rapidly, probably on timescales of

description: We compute entanglement entropy (EE) of a spherical region in $(3+1)$-dimensional $\mathcal{N}=4$ supersymmetric $SU(N)$ Yang-Mills theory in states described holographically by probe D3-branes in $AdS_5 \times S^5$. We do so by generalising methods for computing EE from a probe brane action without having to determine the probe's back-reaction. On the Coulomb branch with $SU(N)$ broken to $SU(N-1)\times U(1)$, we find the EE monotonically decreases as the sphere's radius increases, consistent with the $a$-theorem. The EE of a symmetric-representation Wilson line screened in $SU(N-1)$ also monotonically decreases, although no known physical principle requires this. A spherical soliton separating $SU(N)$ inside from $SU(N-1)\times U(1)$ outside had been proposed to model an extremal black hole. However, we find the EE of a sphere at the soliton's radius does not scale with the surface area. For both the screened Wilson line and soliton, the EE at large radius is described by a position-dependent W-boson mass as a short-distance cutoff. Our holographic results for EE and one-point functions of the Lagrangian and stress-energy tensor show that at large distance the soliton looks like a Wilson line in a direct product of fundamental representations.

Geometrical origins of the Universe dark sector: string-inspired torsion and anomalies as seeds for inflation and dark matter

description: In a modest attempt to present potentially new paradigms in Cosmology, including its inflationary epoch, and initiate discussions, I review in this article some novel, string-inspired cosmological models, which entail a purely geometrical origin of the Dark sector of the Universe but also of its observed matter-antimatter asymmetry. The models contain gravitational (string-model independent, Kalb-Ramond (KR)) axion fields coupled to primordial gravitational anomalies via CP-violating interactions. The anomaly terms are four-space-time-dimensional remnants of the Green-Schwarz counterterms appearing in the definition of the field strength of the spin-one antisymmetric tensor field of the (bosonic) massless gravitational string multiplet, which also plays the rôle of a totally antisymmetric component of torsion. I show how in such cosmologies the presence of primordial gravitational waves can lead to anomaly condensates and dynamical inflation of a "running-vacuum-model" type, without external inflatons, but also to leptogenesis in the radiation era due to anomaly-induced Lorentz and CPT Violating KR axion backgrounds. I also discuss how the torsion-related KR-axion could acquire a mass during the QCD epoch, thus playing the role of (a component of) Dark Matter. Phenomenological considerations of the inflationary and post-inflationary (in particular, modern) eras of the model are briefly discussed, including its potential for alleviating the observed tensions in the cosmological data of the current epoch.

description: We propose simple scoto-seesaw models to account for dark matter and neutrino masses with spontaneous CP violation. This is achieved with a single horizontal $\mathcal{Z}_8$ discrete symmetry, broken to a residual $\mathcal{Z}_2$ subgroup responsible for stabilizing dark matter. CP is broken spontaneously via the complex vacuum expectation value of a scalar singlet, inducing leptonic CP-violating effects. We find that the imposed $\mathcal{Z}_8$ symmetry pushes the values of the Dirac CP phase and the lightest neutrino mass to ranges already probed by ongoing experiments, so that normal-ordered neutrino masses can be cornered by cosmological observations and neutrinoless double beta decay experiments.

Analytical description of these wave patterns is carried out by means of our modification of the direct algebraic balance method. In the case when the analytical description fails, we propose to approximate invariant travelling wave solutions by means of an infinite series of exponential functions. The effectiveness of the method of approximation is demonstrated on a hyperbolic modification of Burgers equation.

For the final target of this campaign, $θ$ Cep, we can now present an orbital solution based on a homogeneously covered radial velocity curve. The period of this single-lined spectroscopic binary turns out to be significantly larger and the orbit is much more eccentric compared to the given values in the 9th Catalogue of Spectroscopic Binary Orbits.

description: We present the preliminary detection of a stellar halo in the nearby, edge-on galaxy, NGC 4244. Using data from the Hubble Space Telescope's Advanced Camera for Surveys (HST/ACS), we have examined number counts of red giant branch (RGB) stars along the minor axis of the galaxy out to 10 kpc, with a limiting surface brightness of mu_R ~ 31 mag/arcsec^2. At distances more than 2.5 kpc above the disk, a second stellar component is clearly visible. This component is well fit by either an exponential or a power law. The best-fit exponential scale height is similar to the scale length of the galaxy disk, suggesting that we are indeed detecting a halo component. Furthermore, the color of the RGB stars above 2.5 kpc are significantly bluer than those in the disk, suggesting a more metal-poor population. Outside the local group, this finding represents one of the first detections of a resolved stellar halo in a spiral galaxy.

description: The many surface reconstructions of (110)-oriented lanthanum--strontium manganite (La$_{0.8}$Sr$_{0.2}$MnO$_3$, LSMO) were followed as a function of the oxygen chemical potential ($μ_\text{O}$) and the surface cation composition. Decreasing $μ_\text{O}$ causes Mn to migrate across the surface, enforcing phase separation into A-site-rich areas and a variety of composition-related, structurally diverse B-site-rich reconstructions. The composition of these phase-separated structures was quantified with scanning tunneling microscopy (STM), and these results were used to build a 2D phase diagram of the LSMO(110) equilibrium surface structures.

description: This paper addresses the issue of matching rigid and articulated shapes through probabilistic point registration. The problem is recast into a missing data framework where unknown correspondences are handled via mixture models. Adopting a maximum likelihood principle, we introduce an innovative EM-like algorithm, namely the Expectation Conditional Maximization for Point Registration (ECMPR) algorithm. The algorithm allows the use of general covariance matrices for the mixture model components and improves over the isotropic covariance case. We analyse in detail the associated consequences in terms of estimation of the registration parameters, and we propose an optimal method for estimating the rotational and translational parameters based on semi-definite positive relaxation. We extend rigid registration to articulated registration. Robustness is ensured by detecting and rejecting outliers through the addition of a uniform component to the Gaussian mixture model at hand. We provide an in-depth analysis of our method and we compare it both theoretically and experimentally with other robust methods for point registration.

description: We propose a novel prediction interval (PI) method for uncertainty quantification, which addresses three major issues with the state-of-the-art PI methods. First, existing PI methods require retraining of neural networks (NNs) for every given confidence level and suffer from the crossing issue in calculating multiple PIs. Second, they usually rely on customized loss functions with extra sensitive hyperparameters for which fine tuning is required to achieve a well-calibrated PI. Third, they usually underestimate uncertainties of out-of-distribution (OOD) samples leading to over-confident PIs. Our PI3NN method calculates PIs from linear combinations of three NNs, each of which is independently trained using the standard mean squared error loss. The coefficients of the linear combinations are computed using root-finding algorithms to ensure tight PIs for a given confidence level. We theoretically prove that PI3NN can calculate PIs for a series of confidence levels without retraining NNs and it completely avoids the crossing issue. Additionally, PI3NN does not introduce any unusual hyperparameters resulting in a stable performance. Furthermore, we address OOD identification challenge by introducing an initialization scheme which provides reasonably larger PIs of the OOD samples than those of the in-distribution samples. Benchmark and real-world experiments show that our method outperforms several state-of-the-art approaches with respect to predictive uncertainty quality, robustness, and OOD samples identification.

description: The main result of this paper is a proof using real analysis of the monotonicity of the topological entropy for the family of quadratic maps, sometimes called Milnor's Monotonicity Conjecture. In contrast, the existing proofs rely in one way or another on complex analysis. Our proof is based on tools and algorithms previously developed by the authors and collaborators to compute the topological entropy of multimodal maps. Specifically, we use the number of transverse intersections of the map iterates with the so-called critical line. The approach is technically simple and geometrical. The same approach is also used to briefly revisit the superstable cycles of the quadratic maps, since both topics are closely related.

Cavitation erosion of nickel aluminides
Creators: name: Salvi, Raj P.
Publisher: name: University of British Columbia
Year: 2009

description: Cavitation erosion is a major problem encountered in hydraulic machinery components. Presently, solution to the problem is sought through a two-fold approach of machine design and application of cavitation resistant materials. Stainless steels are commonly used for cavitation protection. Cobalt based alloys (stellites) and NiTi intermetallic compound are the best materials at present known to resist cavitation erosion. Physical and mechanical properties of various tested materials do not seem to correlate well with the cavitation erosion resistance of these materials. The present study was done to investigate the cavitation erosion resistance of the intermetallic nickel aluminides Ni₃Al and NiAl. An ultrasonic (20 KHz) vibratory test apparatus was used to conduct tests with a modification to the ASTM G-32-92 method. The cavitation intensity and the surface finish were varied, from the specification, to investigate their effects on the cavitation erosion resistance of NiAl. Scanning electron microscopy and X-ray diffraction methods were used as aids in analyzing the results. Unalloyed stoichiometric Ni₃Al was found to exhibit a higher cavitation erosion resistance that boron (0.2 wt. %) doped Ni₃Al. Alloying with boron imparts room temperature ductility to the otherwise brittle Ni₃Al compound. Investigations of deviation from stoichiometry were conducted on NiAl in the compositional range of 47 - 62.2 at. % Ni in this work. The erosion rate was found to decrease monotomically with increasing nickel content, in the range tested. Strain induced martensitic transformation was found to be associated with the compositions which showed the low cavitation erosion rates. Thermally induced martensite which was present in these compositions, was found to be detrimental to the cavitation erosion resistance of NiAl. NiAl compositions of 58 at. % Ni and 62.2 at. % Ni showed cavitation erosion resistance comparable to that of the best known intermetallic NiTi. However, in terms of materials processing NiAl offers advantages over NiTi. Hence NiAl could find a niche as an industrially important material for cavitation protection of hydraulic machinery. The most desirable NiAl compositions exhibit unusual but desirable variations of erosion rate with cavitation intensity. Further studies are needed for a better understanding of this phenomenon.

description: We study in the framework of relativistic quantum mechanics the evolution of a system of two Dirac neutrinos that mix with each other and have non-vanishing magnetic moments. The dynamics of this system in an external magnetic field is determined by solving the Pauli-Dirac equation with a given initial condition. We consider first neutrino spin-flavor oscillations in a constant magnetic field and derive an analytical expression for the transition probability of spin-flavor conversion in the limit of small magnetic interactions. We then investigate ultrarelativistic neutrinos in an transversal magnetic field and derive their wave functions and transition probabilities with no limitation for the size of transition magnetic moments. Although we consider neutrinos, our formalism is straightforwardly applicable to any spin-1/2 particles.

The regression analysis has been conducted to see the causal proficiency of set of variables on the consequential character that is Income of both temporary and permanent laborers. This have been done to establish and estimate the pattern, direction and intensity of interaction of change in income of temporary and permanent laborers to ultimately estimate the ecological behavior of that tea garden setup to eventually derive and elicit their behavioral traits in the changing climatic, biological and physical setup in tea garden ecosystem.

description: We develop a simple coordinate transformation which can be employed to compensate for the nonlinearity introduced by a Microwave Kinetic Inductance Detector's (MKID) homodyne readout scheme. This coordinate system is compared to the canonically used polar coordinates and is shown to improve the performance of the filtering method often used to estimate a photon's energy. For a detector where the coordinate nonlinearity is primarily responsible for limiting its resolving power, this technique leads to increased dynamic range, which we show by applying the transformation to data from a hafnium MKID designed to be sensitive to photons with wavelengths in the 800 to 1300 nm range. The new coordinates allow the detector to resolve photons with wavelengths down to 400 nm, raising the resolving power at that wavelength from 6.8 to 17.

description: Organic Rankine Cycle (ORC) systems are considered as one of the cost suitable technologies toproduce electricity from low-temperature sources. ORC units can efficiently convert low-temperaturesolar energy into electric and thermal power. Independently from the solar technology used, the hourlyand the seasonal fluctuations of solar energy entail challenging dynamic effects and bring these systemsto operate in off-design conditions. Such effects are even more influential at micro-to-small scalesgranting paramount importance to the comprehensive understanding of their behavior.In this study, the annual performances of a 4 kWe/50 kWth solar ORC trigenerative system forresidential applications are numerically investigated. Four different modeling approaches commonlyused in annual system-level simulations of ORC systems are compared. These models differ in thesystem-level modeling approach and the components modeling method. The analysis has shown thatthe simplest ORC model results in the lowest discrepancy compared to the model with the leastassumption, in which the components are modeled empirically, and the high and low pressures of thesystem are found iteratively. The difference between the produced electric energy using the four modelsis significantly higher in hot months, in which the average temperature of the water tank is high due tothe requirements of the vapor generator of the absorption chiller. In this case, the expander pressureratio drops drastically depending on the system model algorithm, which affects the produced electricpower depending on the adopted expander model. On the contrary, the discrepancy between the modelsfor the produced thermal energy is negligible.

description: We consider a stochastically perturbed reaction diffusion equation in a bounded interval, with boundary conditions imposing the two stable phases at the endpoints. We investigate the asymptotic behavior of the front separating the two stable phases, as the intensity of the noise vanishes and the size of the interval diverges. In particular, we prove that, in a suitable scaling limit, the front evolves according to a one-dimensional diffusion process with a non-linear drift accounting for a "soft" repulsion from the boundary. We finally show how a "hard" repulsion can be obtained by an extra diffusive scaling.

description: Intermediate band solar cells (IBSCs) pursue the increase in efficiency by absorbing below-bandgap energy photons while preserving the output voltage. Experimental IBSCs based on quantum dots have already demonstrated that both below-bandgap photon absorption and the output voltage preservation, are possible. However, the experimental work has also revealed that the below-bandgap absorption of light is weak and insufficient to boost the efficiency of the solar cells. The objective of this work is to contribute to the study of this absorption by manufacturing and characterizing a quantum dot intermediate band solar cell with a single quantum dot layer with and without light trapping elements. Using one-dimensional substrate texturing, our results show a three-fold increase in the absorption of below bandgap energy photons in the lowest energy region of the spectrum, a region not previously explored using this approach. Furthermore, we also measure, at 9K, a distinguished split of quasi-Fermi levels between the conduction and intermediate bands, which is a necessary condition to preserve the output voltage of the cell.

description: X-ray photoelectron emission microscopy in combination with x-ray magnetic circular dichroism is used to investigate the influence of an applied magnetic field on Néel caps (i.e., surface terminations of asymmetric Bloch walls). Self-assembled micron-sized Fe(110) dots displaying a moderate distribution of size and aspect ratios serve as model objects. Investigations of remanent states after application of an applied field along the direction of Néel-cap magnetization give clear evidence for the magnetization reversal of the Néel caps around 120 mT, with a $\pm$20 mT dispersion. No clear correlation could be found between the value of the reversal field and geometrical features of the dots.

description: We present an optical analysis of 55 members of R136, the central cluster in the Tarantula Nebula of the Large Magellanic Cloud. Our sample was observed with STIS aboard the Hubble Space Telescope, is complete down to about 40\,$M_{\odot}$, and includes 7 very massive stars with masses over 100\,$M_{\odot}$. We performed a spectroscopic analysis to derive their physical properties. Using evolutionary models we find that the initial mass function (IMF) of massive stars in R136 is suggestive of being top-heavy with a power-law exponent $γ\approx 2 \pm 0.3$, but steeper exponents cannot be excluded. The age of R136 lies between 1 and 2\,Myr with a median age of around 1.6\,Myr. Stars more luminous than $\log L/L_{\odot} = 6.3$ are helium enriched and their evolution is dominated by mass loss, but rotational mixing or some other form of mixing could be still required to explain the helium composition at the surface. Stars more massive than 40\,$M_{\odot}$ have larger spectroscopic than evolutionary masses. The slope of the wind-luminosity relation assuming unclumped stellar winds is $2.41\pm0.13$ which is steeper than usually obtained ($\sim 1.8$). The ionising ($\log Q_0\,[{\rm ph/s}] = 51.4$) and mechanical ($\log L_{\rm SW}\,[{\rm erg/s}] = 39.1$) output of R136 is dominated by the most massive stars ($>100\,M_{\odot}$). R136 contributes around a quarter of the ionising flux and around a fifth of the mechanical feedback to the overall budget of the Tarantula Nebula. For a census of massive stars of the Tarantula Nebula region we combined our results with the VLT-FLAMES Tarantula Survey plus other spectroscopic studies. We observe a lack of evolved Wolf-Rayet stars and luminous blue and red supergiants.

A transient, three-dimensional, thermal model of a billet reheating furnace
Creators: name: Scholey, Kenneth Erwin
Publisher: name: University of British Columbia
Year: 2009

description: Situated between the casting and rolling operations, the reheating process ensures steel billets or slabs are at temperatures high enough (~1200°C) to enable subsequent deformation pro-cesses to be carried out economically. Industrial reheating furnaces have varying designs, utilize different fuel mixtures and employ top, side or bottom firing. Under steady-state operating cond-itions, the challenge is to achieve good temperature homogenization while minimizing fuel con-sumption and maximising furnace throughput. During furnace stoppages, which are caused by delays in therolling mill, there is a need to minimise fuel consumption and maintain discharge temperatures. To gain better insight into the operation of a billet reheating furnace, a transient, three-dimen-sional thermal model has been developed. Radiative heat transfer in three-dimensions is solved using Hottel's "Zone Method", employing a clear-plus-three-grey gas model to represent the furnace atmosphere. In this method, the geometrical aspects of the problem are treated sepa-rately to produce total exchange areas that can be stored for repeated use. The main module then calculates the energy released through combustion, the heat transferred to the steel and the move-ment of the charge during each time step. Gas temperatures are determined from energy balances using a Newton-Raphson iterative technique. Conduction in the billets is solved in three-dimensions by taking into account heat transfer in the gaps between and underneath the billets. The model further evaluates heat losses through the furnace roof, walls and hearth. The mathematical model was verified using industrial data obtained from plant trials con-ducted at two Canadian steel mini-mills. Results from the plant trials indicated that the billets con-tinued to increase in temperature during furnace stoppages. The model suggests that this is due to continuous burner firing during these stoppages even with lower firing levels. For one of the furnaces, the model predicts the thermal efficiency to be 31% for the heating of 0.15 m (6") billets, with 68% of the combustion energy lost in the flue gases and the remainder lost through the refractory. Improved performance could be realized through better control of the furnace atom-sphere, with the air/fuel ratios maintained at levels closer to stoichiometric, as well as the installa- tion of a recuperator to preheat the combustion air. Different delay firing strategies that focussed on the recovery of the furnace were examined with the model and it was found that the sequential return to steady-state firing reduces the extent of billet over-heating while ensuring newly charged billets reached adequate rolling temperatures. The model was also used to examine the effect of air/fuel ratios in each of the furnace control zones and the benefits of recuperatively preheating the combustion air or hot-charging, where the billets are charged into the furnace soon after casting.
Cold collisions in strong laser fields: partial wave analysis of magnesium collisions

description: We have developed Monte Carlo wave function simulation schemes to study cold collisions between magnesium atoms in a strong red-detuned laser field. In order to address the strong-field problem, we extend the Monte Carlo wave function framework to include the partial wave structure of the three-dimensional system. The average heating rate due to radiative collisions is calculated with two different simulation schemes which are described in detail. We show that the results of the two methods agree and give estimates for the radiative collision heating rate for $^{24}$Mg atoms in a magneto-optical trap based on the $^1$S$_0$-$^1$P$_1$ atomic laser cooling transition.

description: We present high-angular-resolution radio observations of the Arches cluster in the Galactic centre, one of the most massive young clusters in the Milky Way. The data were acquired in two epochs and at 6 and 10 GHz with the Karl G. Jansky Very Large Array (JVLA). The rms noise reached is three to four times better than during previous observations and we have almost doubled the number of known radio stars in the cluster. Nine of them have spectral indices consistent with thermal emission from ionised stellar winds, one is a confirmed colliding wind binary (CWB), and two sources are ambiguous cases. Regarding variability, the radio emission appears to be stable on timescales of a few to ten years. Finally, we show that the number of radio stars can be used as a tool for constraining the age and/or mass of a cluster and also its mass function.

description: Recently a type of neural networks called Generative Adversarial Networks (GANs) has been proposed as a solution for fast generation of simulation-like datasets, in an attempt to bypass heavy computations and expensive cosmological simulations to run in terms of time and computing power. In the present work, we build and train a GAN to look further into the strengths and limitations of such an approach. We then propose a novel method in which we make use of a trained GAN to construct a simple autoencoder (AE) as a first step towards building a predictive model. Both the GAN and AE are trained on images issued from two types of N-body simulations, namely 2D and 3D simulations. We find that the GAN successfully generates new images that are statistically consistent with the images it was trained on. We then show that the AE manages to efficiently extract information from simulation images, satisfyingly inferring the latent encoding of the GAN to generate an image with similar large scale structures.
