description: We introduce the Directional Gradient-Curvature (DGC) method, a novel approach for filling gaps in gridded environmental data. DGC is based on an objective function that measures the distance between the directionally segregated normalized squared gradient and curvature energies of the sample and entire domain data. DGC employs data-conditioned simulations, which sample the local minima configuration space of the objective function instead of the full conditional probability density function. Anisotropy and non-stationarity can be captured by the local constraints and the direction-dependent global constraints. DGC is computationally efficient and requires minimal user input, making it suitable for automated processing of large (e.g., remotely sensed) spatial data sets. Various effects are investigated on synthetic data. The gap-filling performance of DGC is assessed in comparison with established classification and interpolation methods using synthetic and real satellite data, including a skewed distribution of daily column ozone values. It is shown that DGC is competitive in terms of cross validation performance.

description: GASPS is a far-infrared line and continuum survey of protoplanetary and young debris disks using PACS on the Herschel Space Observatory. The survey includes [OI] at 63 microns, as well as 70, 100 and 160um continuum, with the brightest objects also studied in [OI]145um, [CII]157um, H2O and CO. Targets included T Tauri stars and debris disks in 7 nearby young associations, and a sample of isolated Herbig AeBe stars. The aim was to study the global gas and dust content in a wide disk sample, systemically comparing the results with models. In this paper we review the main aims, target selection and observing strategy. We show initial results, including line identifications, sources detected, and a first statistical study. [OI]63um was the brightest line in most objects, by a factor of ~10. Detection rates were 49%, including 100% of HAeBe stars and 43% of T Tauri stars. Comparison with published dust masses show a dust threshold for [OI]63um detection of ~1e-5 M_solar. Normalising to 140pc distance, 32% with mass 1e-6 - 1e-5 M_solar, and a small number with lower mass were also detected. This is consistent with moderate UV excess and disk flaring. In most cases, continuum and line emission is spatially and spectrally unresolved, suggesting disk emission. ~10 objects were resolved, likely from outflows. Detection rates in [OI]145um, [CII]157um and CO J=18-17 were 20-40%, but [CII] was not correlated with disk mass, suggesting it arises instead from a compact envelope. [OI] detection rates in T Tauri associations of ages 0.3-4Myr were ~50%. ~2 stars were detectable in associations of 5-20Myr, with no detections in associations of age >20Myr. Comparing with the total number of young stars, and assuming a ISM-like gas/dust ratio, this indicates that ~18% of stars retain a gas-rich disk of total mass >1M_Jupiter for 1-4Myr, 1-7% keep such disks for 5-10Myr, and none remain beyond 10-20Myr.

Incorporating Context Information into Deep Neural Network Acoustic Models

description: The introduction of deep neural networks (DNNs) has advanced the performance of automatic speech recognition (ASR) tremendously. On a wide range of ASR tasks, DNN models show superior performance than the traditional Gaussian mixture models (GMMs). Although making significant advances, DNN models still suffer from data scarcity, speaker mismatch and environment variability. This thesis resolves these challenges by fully exploiting DNNs’ ability of integrating heterogeneous features under the same optimization objective. We propose to improve DNN models under these challenging conditions by incorporating context information into DNN training. On a new language, the amount of training data may become highly limited. This data scarcity causes degradation on the recognition accuracy of DNN models. A solution is to transfer knowledge from other languages to the low-resource condition. This thesis proposes a framework to build cross-language DNNs via languageuniversal feature extractors (LUFEs). Convolutional neural networks (CNNs) and deep maxout networks (DMNs) are employed to improve the quality of LUFEs, which enables the generation of invariant and sparse feature representations. This framework notably improves the recognition accuracy on a wide range of low-resource languages. The performance of DNNs degrades when the mismatch between acoustic models and testing speakers exists. A form of context information which encapsulates speaker characteristics is i-vectors. This thesis proposes a novel framework to perform feature-space speaker adaptive training (SAT) for DNN models. A key component of this approach is an adaptation network which takes i-vectors as inputs and projects DNN inputs into a normalized feature space. The DNN model fine-tuned in this new feature space rules out speaker variability and becomes more independent of specific speakers. This SAT method is applicable to different feature types and model architectures. The proposed adaptive training framework is further extended to incorporate distance- and video-related context information. The distance descriptors are extracted from deep learning models which are trained to distinguish distance types on the frame level. Distance adaptive training (DAT) using these descriptors captures speaker-microphone distance dynamically on the frame level. When performing ASR on video data, we naturally have access to both the speech and the video modality. Video- and segment-level visual features are extracted from the video stream. Video adaptive training (VAT) with these visual features results in more robust acoustic models that are agnostic to environment variability. Moreover, the proposed VAT approach removes the need for frame-level visual features and thus achieves audio-visual ASR on truly open-domain videos.

Self-propulsion in viscoelastic fluids: pushers vs. pullers

description: We use numerical simulations to address locomotion at zero Reynolds number in viscoelastic (Giesekus) fluids. The swimmers are assumed to be spherical, to self-propel using tangential surface deformation, and the computations are implemented using a finite element method. The emphasis of the study is on the change of the swimming kinematics, energetics, and flow disturbance from Newtonian to viscoelastic, and on the distinction between pusher and puller swimmers. In all cases, the viscoelastic swimming speed is below the Newtonian one, with a minimum obtained for intermediate values of the Weissenberg number, $We$. An analysis of the flow field places the origin of this swimming degradation in non-Newtonian elongational stresses. The power required for swimming is also systematically below the Newtonian power, and always a decreasing function of $We$. A detail energetic balance of the swimming problem points at the polymeric part of the stress as the primary $We$-decreasing energetic contribution, while the contributions of the work done by the swimmer from the solvent remain essentially $We$-independent. In addition, we observe negative values of the polymeric power density in some flow regions, indicating positive elastic work by the polymers on the fluid. The hydrodynamic efficiency, defined as the ratio of the useful to total rate of work, is always above the Newtonian case, with a maximum relative value obtained at intermediate Weissenberg numbers. Finally, the presence of polymeric stresses leads to an increase of the rate of decay of the flow velocity in the fluid, and a decrease of the magnitude of the stresslet governing the magnitude of the effective bulk stress in the fluid.

description: We establish that, over certain ground fields, the set of osculating tangents of Cayley's ruled cubic surface gives rise to a (maximal partial) spread which is also a dual (maximal partial) spread. It is precisely the Betten-Walker spreads that allow for this construction. Every infinite Betten-Walker spread is not an algebraic set of lines, but it turns into such a set by adding just one pencil of lines.

description: Acoustic flow velocity and direction meters from the IST series, which can be integrated into various measuring systems, are considered. The simulation of the flow profile in the measuring tube was carried out depending on the free flow velocity. A measurement method has been developed that uses the transit time of repeated acoustic signals reflected from the transducers, which makes it possible to take into account time hardware delays and a change in the length of the measuring base, which affect the determination of the speed of sound and flow, while increasing the accuracy of measuring the sound speed parameters with simultaneous measuring the flow velocity and temperatures for liquid media of different densities.

On spectral disjointness of powers for rank-one transformations and Möbius orthogonality

description: We study the spectral disjointness of the powers of a rank-one transformation. For a large class of rank-one constructions, including those for which the cutting and stacking parameters are bounded, and other examples such as rigid generalized Chacon's maps and Katok's map, we prove that different positive powers of the transformation are pairwise spectrally disjoint on the continuous part of the spectrum. Our proof involves the existence, in the weak closure of {U_T^k: k in Z}, of "sufficiently many" analytic functions of the operator U_T. Then we apply these disjointness results to prove Sarnak's conjecture for the (possibly non-uniquely ergodic) symbolic models associated to these rank-one constructions: All sequences realized in these models are orthogonal to the Möbius function.

description: In digital transformation, incumbents are pressured to exploit their core business and simultaneously explore opportunities for digital innovation. When pursuing ambidexterity, organizations establish digital innovation units (DIUs) dedicated to digital innovation. Due to the novelty of the phenomenon, prior studies targeted DIUs' design, objectives, and challenges. However, their value lies in reintegrating digital innovations back into the operational organization for use and commercialization, which has been neglected so far. Thus, we analyze the reintegration based on a single-embedded case study of four heterogeneous DIUs. We identify three phases of reintegration activities and trace differences to the contextual factors: innovation orientation, number of involved entities, and ownership. Our contribution is twofold. First, we shed light on the reintegration of DIUs' innovation outcomes for the first time. Second, we extend research on digital innovation and ambidexterity by outlining drivers and inhibitors of reintegration, enhancing our understanding of how organizations can exploit exploration.

description: Using first-principles methods based on density-functional theory we investigate the spin relaxation in W(001) ultrathin films. Within the framework of the Elliott-Yafet theory we calculate the spin mixing of the Bloch states and we explicitly consider spin-flip scattering off self-adatoms. We find an oscillatory behavior of the spin-mixing parameter and relaxation rate as a function of the film thickness, which we trace back tosurface-state properties. We also analyze the Rashba effect experienced by the surface states and discuss its influence on the spin relaxation. Finally we calculate the anisotropy of the spin-relaxation rate with respect to the polarization direction of the excited spin population relative to the crystallographic axes of thefilm. We find that the spin-relaxation rate can increase by as much as 47% when the spin polarization is directed out of plane, compared to the case when it is in plane. Our calculations are based on the multiple-scattering formalism of the Korringa-Kohn-Rostoker Green-function method.

Narrow-line HI and cold structures in the ISM

Year: 2013
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: Context. In the HI line profiles in the Leiden-Argentina-Bonn (LAB) all-sky database, we have found a population of very cold HI clouds. So far, the role of these clouds in the interstellar medium (ISM) has remained unclear. Aims. In this paper, we attempt to confirm the existence of the narrow-line HI emission (NHIE) clouds by using the data from the Parkes Galactic all-sky survey (GASS) and try to find their place among other coldest constituents of the ISM. Methods. We repeat the search of NHIE with the GASS data and derive or compile some preliminary estimates for the distribution, temperatures, distances, linear sizes, column and number densities, masses, and the composition of NHIE clouds, and compare these data with corresponding estimates for HI self-absorption (HISA) features, the Planck cold clumps (CC), and infrared dark clouds (IRDC). Results. We demonstrate that from LAB and GASS we can separate comparable NHIE complexes, and the properties of the obtained NHIE clouds are very similar to those of HISA features, but both of these types of clouds are somewhat warmer and more extended and have lower densities than the cores in the Planck CC and IRDC. Conclusions. We conclude that NHIE may be the same type of clouds as HISA, but in different observing conditions, in the same way as the Planck CC and IRDC are most likely similar ISM structures in different observing conditions and probably in slightly different evolutionary stages. Both NHIE and HISA may be an intermediate phase between the diffuse cold neutral medium and star-forming molecular clumps represented by the Planck CC and IRDC.

Hardening transition in a one-dimensional model for ferrogels

description: We introduce and investigate a coarse-grained model for quasi one-dimensional ferrogels. In our description the magnetic particles are represented by hard spheres with a magnetic dipole moment in their centers. Harmonic springs connecting these spheres mimic the presence of a cross-linked polymer matrix. A special emphasis is put on the coupling of the dipolar orientations to the elastic deformations of the matrix, where a memory effect of the orientations is included. Although the particles are displaced along one spatial direction only, the system already shows rich behavior: as a function of the magnetic dipole moment, we find a phase transition between "soft-elastic" states with finite interparticle separation and finite compressive elastic modulus on the one hand, and "hardened" states with touching particles and therefore diverging compressive elastic modulus on the other hand. Corresponding phase diagrams are derived neglecting thermal fluctuations of the magnetic particles. In addition, we consider a situation in which a spatially homogeneous magnetization is initially imprinted into the material. Depending on the strength of the magneto-mechanical coupling between the dipole orientations and the elastic deformations, the system then relaxes to a uniaxially ferromagnetic, an antiferromagnetic, or a spiral state of magnetization to minimize its energy. One purpose of our work is to provide a largely analytically solvable approach that can provide a benchmark to test future descriptions of higher complexity. From an applied point of view, our results could be exploited, for example, for the construction of novel damping devices of tunable shock absorbance.

description: Urmia Lake is a hyper-saline lake in northwestern Iran that has been drying up since 2005. The main objective of this study was to evaluate the water quality in aquifers that are the main source of fresh water for the eastern plains Urmia Lake, which has been drying up due to intensive land use/cover changes and climate change. We evaluated hydro-geochemical data and factors contributing to aquifer pollution and quality variation for nine aquifers in the vicinity of Urmia Lake during the dry and wet seasons from 2000–2020. Our methodology was based on the analysis of 10 years of data from 356 deep and semi-deep wells using GIS spatial analysis, multivariate statistical analysis, and agglomerative hierarchical clustering. We developed a Water Quality Index (WQI) for spatiotemporal assessment of the status of the aquifers. In doing so, we highlighted the value of combining Principal Component Analysis (PCA), WQI, and GIS to determine the hydro-geochemical attributes of the aquifers. We found that the groundwater in central parts of the study area was unsuitable for potable supplies. Anthropogenic sources of contamination, such as chemical fertilizers, industrial waste, and untreated sewage water, might be the key factors causing excessive concentrations of contaminants affecting the water quality. The PCA results showed that over 80% of the total variance could be attributed to two principal factors for most aquifers and three principal factors for two of the aquifers. We employed GIS-based spatial analysis to map groundwater quality in the study area. Based on the WQI values, approximately 48% of groundwater samples were identified as poor to unsuitable for drinking purposes. Results of this study provide a better hydro-geochemical understanding of the multiple aquifers that require preventive action against groundwater damage. We conclude that the combined approach of using a multivariate statistical technique and spatial analysis is effective for determining the factors controlling groundwater quality.

description: Using Rule 126 elementary cellular automaton (ECA) we demonstrate that a chaotic discrete system --- when enriched with memory -- hence exhibits complex dynamics where such space exploits on an ample universe of periodic patterns induced from original information of the ahistorical system. First we analyse classic ECA Rule 126 to identify basic characteristics with mean field theory, basins, and de Bruijn diagrams. In order to derive this complex dynamics, we use a kind of memory on Rule 126; from here interactions between gliders are studied for detecting stationary patterns, glider guns and simulating specific simple computable functions produced by glider collisions.
Ab initio calculations of phonon spectra in ATiO3 perovskite crystals (A = Ca, Sr, Ba, Ra, Cd, Zn, Mg, Ge, Sn, Pb)

description: The phonon spectra of calcium, strontium, barium, radium, cadmium, zinc, magnesium, germanium, tin, and lead titanates with the perovskite structure are calculated from first principles within the density functional theory. By analyzing the unstable modes in the phonon spectra, the possible lattice distortions are determined and the energies of the corresponding phases are calculated. From analyzing the phonon spectra, force constants, and eigenvectors of TO phonons, a conclusion is drawn on the origin of the ferroelectricity in considered crystals. It is shown that the main factors determining the possible off-centering of atoms in the A position are the geometric size and electronic configuration of these atoms.

description: Idempotent integration is an analogue of the Lebesgue integration where $σ$-additive measures are replaced by $σ$-maxitive measures. It has proved useful in many areas of mathematics such as fuzzy set theory, optimization, idempotent analysis, large deviation theory, or extreme value theory. Existence of Radon--Nikodym derivatives, which turns out to be crucial in all of these applications, was proved by Sugeno and Murofushi. Here we show a converse statement to this idempotent version of the Radon--Nikodym theorem, i.e. we characterize the $σ$-maxitive measures that have the Radon--Nikodym property.

title: Efficient removal of natural organic matter from drinking water for reducing disinfection by-products
Creators: name: Tafvizi, Hoda
Publisher: name: Memorial University of Newfoundland
Year: 2022

description: Chlorine as a low-cost bactericide has been used for more than a century for the disinfection of drinking water. However, the contact between chlorine-based disinfectants and natural organic matter (NOM) leads to the production of hazardous disinfection by-products (DBPs). Trihalomethanes (THMs) and haloacetic acids (HAAs) as two groups of regulated DBPs by U.S. EPA and Health Canada have been of concern in the last two decades for the water treatment facilities around the world, specifically small communities of Newfoundland. Enhanced coagulation (EC) and adsorption with activated carbon (AC) are two recommended methods by U.S. EPA for the removal of NOM. Although many studies have tested these methods in full scale and lab scale for the removal of dissolved organic carbon as the main precursor of THMs and HAAs, certain environmental factors in NL (e.g., seasonal variations) and treatment factors (i.e., fast mixing and settling time in EC, and aluminum coating in AC) have not been considered so far. This research aims to (i) examine the effect of five factors of pH, coagulant dosage, coagulant type, fast mixing speed, and settling time simultaneously on the removal of DBPs rather than DOC. (ii) establish prediction models for the removal of DOC and reduction of THMs and HAA5 based on NL water characteristics. (iii) decrease the power consumption of EC. (iv) to reduce the coagulant dosages (v) improve the mesoporosity of activated carbon for NOM removal by chemical activation using nitric acid and physical activation, (vi) enhance the removal of DOC and humic acids by surface charge modification through metal impregnation, (vii) study the efficient removal of NOM by combination of EC and AC (viii) study the variations of NOM characteristics in four communities of NL over two years. (ix) to figure out the most crucial factors affecting the production of HAA5 and THM4. The results of this research on EC confirmed that optimization of EC parameters based on THMs and HAAs reduction, reduced the dosage of coagulant from 6.51-7.85 mg/mg DOC for DOC to 3.83-5.95 mg/mg DOC. Moreover, the energy consumption in the fast-mixing stage was reduced by 59.8%. The fly ash of pulp and paper company in corner brook was used to produce AC. Nitric acid at 10% concentration increased the Brunauer, Emmett and Teller (BET) surface area and pore width of the developed AC in comparison with chemical treatment with nitric acid at 5% concentration. Moreover, metal impregnation with 0.75% Fe and 1.00% Al enhanced the THM4 and HAA5 reduction by 33-44%. The investigation on the NOM characterization in four sources of drinking water in NL over two years revealed that very hydrophobic acid NOM and neutral hydrophilic are the main contributors to the production of HAA5 while very hydrophobic acids (VHAs) are the main precursors of THM4. The highest level of DOC was observed in summer and the highest contributor to the NOM content was VHAs in all seasons.

description: We start a systematic investigation of the possibility to have supersymmetry (SUSY) to be an asymptotic state of the gauge theory in the high energy (UV) limit, due to the renormalization group running of coupling constants of the theory. The answer on whether this situation takes place or not, can be resolved by dealing with the running of the ratios between Yukawa and scalar couplings to the gauge coupling. The behavior of these ratios does not depend too much on whether gauge coupling is asymptotically free (AF) or not. It can be shown that the UV stable fixed point for the Yukawa coupling is not supersymmetric. Taking this into account, one can break down SUSY only in the scalar coupling sector. We consider two simplest examples of such breaking, namely N=1 supersymmetric QED and QCD. In one of the cases one can construct an example of SUSY being restored in the UV regime.
Reverse dynamical evolution of Eta Chamaeleontis

description: In the scope of the star formation process, it is unclear how the environment shapes the initial mass function (IMF). While observations of open clusters propose a universal picture for the IMF from the substellar domain up to a few solar masses, the young association eta Chamaeleontis presents an apparent lack of low mass objects (m<0.1 Msun). Another unusual feature of this cluster is the absence of wide binaries with a separation > 50 AU. We aim to test whether dynamical evolution alone can reproduce the peculiar properties of the association assuming a universal IMF. We use a pure N-body code to simulate the dynamical evolution of the cluster for 10 Myr, and compare the results with observations. A wide range of values for the initial parameters are tested in order to identify the initial state that would most likely lead to observations. In this context we also investigate the influence of the initial binary population on the dynamics and the possibility of having a discontinuous single IMF near the transition to the brown dwarf regime. We consider as an extreme case an IMF with no low mass systems (m<0.1 Msun). The initial configurations cover a wide range of initial density, from 10^2 to 10^8 stars/pc^3, in virialized, hot and cold dynamical state. We do not find any initial state that would evolve from a universal single IMF to fit the observations. Only when starting with a truncated IMF without any very low mass systems and no wide binaries, can we reproduce the cluster core properties with a success rate of 10% at best. Pure dynamical evolution alone cannot explain the observed properties of eta Cha from universal initial conditions. The lack of brown dwarfs and very low mass stars, and the peculiar binary properties (low binary fraction and lack of wide binaries), are probably the result of the star formation process in this association.

description: When a solenoid is embedded in three space, its complement is an open three manifold. We discuss the geometry and fundamental groups of such manifolds, and show that the complements of different solenoids (arising from different inverse limits) have different fundamental groups. Embeddings of the same solenoid can give different groups; in particular, the nicest embeddings are unknotted at each level, and give an Abelian fundamental group, while other embeddings have non-Abelian groups. We show using geometry that every solenoid has uncountably many embeddings with non-homeomorphic complements.

description: Since they started writing during the Hannibalic war Roman historians used to take a Romecentered
view of the world. The paper summerizes the most salient features of the first two centuries of Roman historical writing systematically, treating the causes and prerequisites of its emerging, literary and cultural contexts, and the specific annalistic structure of the later narratives, though Roman historical writing up to and including Livy cannot be subsumed under the umbrella term ‘annalistic’. The development of the genre was in the main determined by individual authors and their works, at its conclusion, in Sallust and Livy it produced
authors whose works offered to the Renaissance and the French Revolution archetypes of civic virtue and its decay.
Cosmological Evolution of Interacting New Holographic Dark Energy in Non-flat Universe

description: We consider the interacting holographic dark energy with new infrared cutoff (involving Hubble parameter and its derivative) in non-flat universe. In this context, we obtain the equation of state parameter which evolutes the universe from vacuum dark energy region towards quintessence region for particular values of constant parameters. It is found that this model always remains unstable against small perturbations. Further, we establish the correspondence of this model having quintessential behavior with quintessence, tachyon, K-essence and dilaton scalar field models. The dynamics of scalar fields and potentials indicate accelerated expansion of the universe which is consistent with the current observations. Finally, we discuss the validity of the generalized second law of thermodynamics in this scenario.
