description: Despite the severe bias of the transit method of exoplanet discovery toward short orbital periods, a modest sample of transiting exoplanets with orbital periods greater than 100 days is known. Long-term radial velocity (RV) surveys are pivotal to confirming these signals and generating a set of planetary masses and densities for planets receiving moderate to low irradiation from their host stars. Here, we conduct RV observations of Kepler-1514 from the Keck I telescope using the High Resolution Echelle Spectrometer. From these data, we measure the mass of the statistically validated giant ($1.108\pm0.023$ $R_{\rm J}$) exoplanet Kepler-1514 b with a 218 day orbital period as $5.28\pm0.22$ $M_{\rm J}$. The bulk density of this cool ($\sim$390 K) giant planet is $4.82^{+0.26}_{-0.25}$ g cm$^{-3}$, consistent with a core supported by electron degeneracy pressure. We also infer an orbital eccentricity of $0.401^{+0.013}_{-0.014}$ from the RV and transit observations, which is consistent with planet-planet scattering and disk cavity migration models. The Kepler-1514 system contains an Earth-size, Kepler Object of Interest on a 10.5 day orbit that we statistically validate against false positive scenarios, including those involving a neighboring star. The combination of the brightness ($V$=11.8) of the host star and the long period, low irradiation, and high density of Kepler-1514 b places this system among a rare group of known exoplanetary systems and one that is amenable to continued study.

description: We report on some properties of the newly observed charged hidden-charmed open strange $ Z_{cs}(3985)^- $ state by BESIII Collaboration. Assigning the quantum numbers $ J^{P} = 1^{+}$ and the quark composition $ c \bar c s\bar u $ and considering it as the strange partner of the famous $ Z_c(3900) $ state, we estimate the mass of the $ Z_{cs}(3985)^- $ resonance in vacuum and compare it with the experimental data. We also investigate its mass, current coupling and vector-self energy in a medium with finite density. Our result on the mass in vacuum agrees well with the experimental data. We estimate the mass and current coupling of the b-partner of this state, $ Z_{bs}$, in the vacuum as well. For its mass we get $ m_{Z_{bs}}= 10732^{+97}_{-46}~\mbox{MeV}$, which may be checked via other nonperturbative approaches as well as future experiments. We present the dependence of the spectroscopic parameters of $ Z_{cs}(3985)^- $ state on density and observe that these parameters are linearly changed with increasing in the density.

COVINFORM
Case Study
Methodology
Vulnerable groups

description: COVINFORM is implementing the use of a socio-ecological systems resilience approach for developing case-studies aiming to identify promising practices in vulnerable communities.

The implementation of such perspective is not easy, particularly when aiming for establishing a common research methodology for case-studies spanning diverse disciplines (social epidemiology, the economics of unpaid labour, the sociology of migration, etc.) and vulnerable populations (COVID-19 patients, precarious families, migrating health care workers, etc.). Moreover, COVINFORM envisages the development of a methodology in a way to allow replication of research in a way that can be comparable and/or complimentary by defining a set a categories and variables for system analysis.

Even though this report presents the main ideas developed during a short first period of COVINFORM lifecycle and only establishes the initial steps for the development and implementation of the research methodology, partners strongly believe this perspective will allow to set a new milestone on the application of a more comprehensive perspective of communities’ resilience that can be applied on future crisis situations.

description: One-class classification is a challenging subfield of machine learning in which so-called data descriptors are used to predict membership of a class based solely on positive examples of that class, and no counter-examples. A number of data descriptors that have been shown to perform well in previous studies of one-class classification, like the Support Vector Machine (SVM), require setting one or more hyperparameters. There has been no systematic attempt to date to determine optimal default values for these hyperparameters, which limits their ease of use, especially in comparison with hyperparameter-free proposals like the Isolation Forest (IF). We address this issue by determining optimal default hyperparameter values across a collection of 246 one-class classification problems derived from 50 different real-world datasets. In addition, we propose a new data descriptor, Average Localised Proximity (ALP) to address certain issues with existing approaches based on nearest neighbour distances. Finally, we evaluate classification performance using a leave-one-dataset-out procedure, and find strong evidence that ALP outperforms IF and a number of other data descriptors, as well as weak evidence that it outperforms SVM, making ALP a good default choice.

description: Analysis of the intriguing physical properties of the dodecaborides, $R$B$_{12}$, requires accurate data on their crystal structure. We show that a simple cubic model fits well with the atomic positions in the unit cell but cannot explain the observed anisotropy in the physical properties. The cooperative Jahn-Teller (JT) effect slightly violates the ideal metric of the cubic lattice and the symmetry of the electron density distribution in the lattice interstices. Theoretical models of the JT distortions of the boron framework are presented. Their correspondence to the electron-density distribution on the maps of Fourier syntheses obtained using x-ray data and explaining the previously observed anisotropy of conductive properties is demonstrated. The effect of boron isotope composition on the character of the lattice distortions is shown. We also discuss the application of the Einstein model for cations and the Debye model for the boron atoms to describe the dynamics of the crystal lattice.

Post-starburst--AGN Connection: Spatially Resolved Spectroscopy of Hdelta-Strong AGNs
Creators: name: Goto, Tomotsugu
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Ever since the co-existence of an active galactic nucleus (AGN) and a starburst was observationally discovered, there has been a significant controversy over whether there is a physical connection between starbursts and AGNs. If yes, it is a subject of interest to reveal which one triggers another. Here we bring a unique insight onto the subject by identifying 840 galaxies with both a post-starburst signature (strong Balmer absorption lines) and an AGN (based on the emission line ratio). These poststarburst-AGNs account for the 4.2% of all the galaxies in a volume-limited sample. The presence of a post-starburst phase with an active AGN itself is of importance, suggesting that AGNs may outlive starbursts in the starburst-AGN connection. In addition, we have performed spatially resolved spectroscopy of three of our poststarbusrst-AGN galaxies, obtaining some evidence that the post-starburst region is more extended, but sharply centred around the central AGN, confirming a spatial connection between the post-starburst and the AGN.

description: We have carried out a comprehensive investigation of the quasiparticle properties of a two-dimensional electron gas, interacting via the long-range Coulomb interaction, in the presence of bare mass anisotropy (i.e. with an elliptic noninteracting Fermi surface) by calculating the self-energy, the spectral function, the scattering rate, and the effective mass within the leading order dynamical self-energy approximation. We find novel anisotropic features of quasiparticle properties that are not captured by the isotropic approximation where the anisotropic effective mass is replaced by the isotropic averaged density-of-states mass. Some of these interesting results are: (1) the renormalization of the quasiparticle spectrum becomes highly anisotropic as the quasiparticle energy increases away from the Fermi energy; (2) the inelastic scattering rate features a strong anisotropy, exhibiting an abrupt jump at different injected energies depending on the momentum direction of the injected electron; (3) the effective mass anisotropy is reduced by interactions. Our results and analysis show that the unjustified neglect of the mass anisotropy can lead to an incorrect description of quasiparticle properties of the anisotropic system although the use of an equivalent isotropic approximation using the density-of-states effective mass works as a reasonable approximation in many situations. We also provide a theory using the plasmon-pole approximation, commenting on its validity for anisotropic self-energy calculations. We comment also on the interaction effect on the Fermi surface topology, finding that the elliptic shape of the bare Fermi surface is preserved, with suppressed ellipticity, in the interacting system to a high degree of accuracy. Our theory provides a complete generalization of the existing isotropic many-body theory of interacting electrons to the corresponding anisotropic systems.

Culture change and ex-change : syncretism and anti-syncretism in Bena, Eastern Highlands, Papua New Guinea /Regina Anne-Marie Knapp.

description: This thesis draws upon existing bodies of work on 'culture change', 'exchange' and 'person' in Melanesia but brings them together in a new way. In the anthropological debate, culture change has often been discussed in relation to understandings of 'development' involving the reproduction and transformation of cultural categories according to an indigenous understanding of exchange and agency. My research suggests that culture change as it is taking place in Bena, Eastern Highlands Province, Papua New Guinea, can best be understood when the model of agentive culture change, first proposed by Sahlins, is conjoined with the theoretical approach of the 'new Melanesian ethnography', especially with Marilyn Strathern's work on agency and personhood. Here, agency is understood in terms of dividuality, partible personhood, composite persons and the decomposition or deconception of persons in exchange. In Bena, the partibility of person is reflected in the perception that every exchange involves personal de- and attachments of an 'essence' called 'nogoya'a' (nurturance). Phillip Newman who worked among a neighbouring group, the Gururumba, found a strikingly similar concept. Unfortunately, his findings have so far been neglected in anthropological literature on Melanesia. This thesis attempts to fill this gap. It reveals how Newman's ethnographic data on 'vital essence' in Gururumba help to clarify the Bena idea of personal partibility expressed in the concept of exchanging personal parts of 'nogoya'a'. In doing so, it provides an insight into the way in which the particular notion of interpersonal exchange in Bena ties in with agentive forms of culture change and explains how the process of merging (or rejecting) elements from other cultures is shaped by the specific Bena understanding of exchange and person. This thesis suggests that culture change in Bena can best be understood as culture ex-change, with exchange being grasped in Bena terms as an ideally reciprocal, nurturing and strengthening flow of vital essence between partible exchange partners.

description: We consider a Pfaffian system expressing isomonodromy of an irregular system of Okubo type, depending on complex deformation parameters u=(u_1,...,u_n), which are eigenvalues of the leading matrix at the irregular singuilarity. At the same time, we consider a Pfaffian system of non-normalized Schlesinger type expressing isomonodromy of a Fuchsian system, whose poles are the deformation parameters u_1,...,u_n. The parameters vary in a polydisc containing a coalescence locus for the eigenvalues of the leading matrix of the irregular system, corresponding to confluence of the Fuchsian singularities. We construct isomonodromic selected and singular vector solutions of the Fuchsian Pfaffian system together with their isomonodromic connection coefficients, so extending a result of references [4] and [20] to the isomonodromic case, including confluence of singularities. Then, we introduce an isomonodromic Laplace transform of the selected and singular vector solutions, allowing to obtain isomonodromic fundamental solutions for the irregular system, and their Stokes matrices expressed in terms of connection coefficients. These facts, in addition to extending [4] and [20] to the isomonodromic case with coalescences/confluences, allow to prove by means of Laplace transform the main result of reference [11], which is the analytic theory of non-generic isomonodromic deformations of the irregular system with coalescing eigenvalues.

description: Dynamical diffraction effects always play a role when working with perfect single crystals. The penetration of X-rays respect to the surface normal during diffraction (extinction depth, $1/σ_e$) in perfect single crystals does not have a constant value. The value changes for different angular positions on the crystal diffraction condition. For higher X-ray energies this value can change from few micrometers to tens of millimeters for each different crystal angular position in the small angular range of the diffraction condition. This effect may spread a single point in the object (sample) as a line in the image detector, especially if the crystal is set (or if the sample angularly deviates the beam) at lower diffraction angle positions, where the surface component of X-ray penetration can achieve huge values. Then, for imaging experiments where the dynamical diffraction occurs, such intrinsic property can affect the image resolution. We have modeled and experimentally checked such a dynamical diffraction property using, as example, an Analyzer-based X-ray phase contrast imaging setup (ABI) at two different X-ray energies: 10.7 keV and 18 keV. The results show that our theoretical model is consistent with the measured results. For higher energies the blur effect is enhanced and intrinsically limits the image spatial resolution.

description: We discuss issues concerning the physical nature of intervening MgII quasar absorption systems in light of results from our recent surveys using SDSS EDR QSO spectra and data obtained at the MMT. These surveys indicate an excess of weak $W_0^{\lambda2796} \lesssim 0.3$Å) systems relative to the exponential dN/dW distribution of stronger systems. The incidence of intermediate-strength lines shows remarkably little evolution with redshift, thereby constraining models for the nature of the clouds comprising these absorbers. The total distribution does evolve, with the incidence decreasing with decreasing redshift in a $W_0^{\lambda2796}$-dependent rate (the strongest systems evolve the fastest). This suggests that multiple populations that evolve at different rates contribute to the incidence in a $W_0^{\lambda2796}$-dependent manner. We also present two images of fields containing unprecedented ``ultra-strong'' ($W_0^{\lambda2796} \ge 4.0$Å) MgII absorbers.

description: In this thesis I examine the local notions of indigenous shell (tabu) and state-issued currencies used by Tolai people of Gazelle Peninsula, East New Britain Province, Papua New Guinea. Following the general viewpoint of the New Melanesian Ethnography as inspired by Marilyn Strathem and Roy Wagner among others, the thesis aims to demonstrate how we can describe, analyse, and understand the relational dimensions of traditional and introduced currencies in terms which are consonant with recent accounts of the sort of 'dividual' personhood that is reportedly distinctive to Melanesia. In Chapter I, I outline Tolai understandings of personhood with respect to the 'traditional' system of social organisation and kinship, focusing upon indigenous conceptualisations of the body. In Chapter 2, I describe how this symbolisation of relations and the body is for villagers a significant aspect also of tabu, providing its conceptual background: its various meanings, mythical understandings, and subunit classification as well shaping the processes of production, exchange, and accumulation in which it has been deployed. In Chapters 3-6, I argue that the indigenous version of dividual personhood has played a key role in the Tolai history of currency utilisation and in the local organization, operation and transformation of various exchange spheres ('barter', 'purchase', 'hire', and 'secular' and 'ceremonial sharing') consequent to the villagers' entry into new relations non-Tolai persons, to the issuing of state currencies, and the introduction of imported commodities.

In spite of a large superparamagnetic contribution due to the small ferromagnetic catalytical particles still present in the sample, at low temperature ($T < 0.5K$) and low magnetic field ($H < 80 Oe$), a diamagnetic signal is detectable. This low temperature diamagnetism can be interpreted as the Meissner effect in ropes of carbon nanotubes which have previously been shown to exhibit superconductivity from transport measurements.

description: Forthcoming large galaxy cluster surveys will yield tight constraints on cosmological models. It has been shown that in an idealized survey, containing > 10,000 clusters, statistical errors on dark energy and other cosmological parameters will be at the percent level. It has also been shown that through "self-calibration", parameters describing the mass-observable relation and cosmology can be simultaneously determined, though at a loss in accuracy by about an order of magnitude. Here we examine the utility of an alternative approach of self-calibration, in which a parametrized ab-initio physical model is used to compute cluster structure and the resulting mass-observable relations. As an example, we use a modified-entropy ("pre-heating") model of the intracluster medium, with the history and magnitude of entropy injection as unknown input parameters. Using a Fisher matrix approach, we evaluate the expected simultaneous statistical errors on cosmological and cluster model parameters. We study two types of surveys, in which a comparable number of clusters are identified either through their X-ray emission or through their integrated Sunyaev-Zel'dovich (SZ) effect. We find that compared to a phenomenological parametrization of the mass-observable relation, using our physical model yields significantly tighter constraints in both surveys, and offers substantially improved synergy when the two surveys are combined. These results suggest that parametrized physical models of cluster structure will be useful when extracting cosmological constraints from SZ and X-ray cluster surveys. (abridged)

Speech, songs, and intermediate vocalizations : a longitudinal study of preschool children’s vocal development
Creators: name: Mang, Esther Ho Shun
Publisher: name: University of British Columbia
Year: 2009

description: The present study is a qualitative and quantitative interdisciplinary investigation of young children's vocal development. It investigated how vocalizations of young children mutate in relation to the children's linguistic and musical development, and the contexts in which these developments take place. Eight girls age eighteen to thirty-eight months participated in this study. Four spoke Chinese and four spoke English as their first language. Each child was visited every four to six months over a 42 month period. Acoustic analyses were performed on recorded vocal responses, and three judges classified the vocalizations and provided perceptual evaluation. It appears that young children have established communicative pitches that are associated with different forms of vocalizations by age two. All children consistently sang with higher fundamental frequencies than they used for speaking, while other forms of vocalization appear to be positioned consistently between singing and speaking. Both the mean fundamental frequency data and the qualitative data suggest some possible differences in vocal pitch behaviours across language. Chinese bilingual children made comparatively less but stable distinction between their speech and song; in their acoustic intermediate vocalizations however, the boundary between speech and song was "fuzzy". English monolingual children made increasingly clearer and wider acoustical distinctions between their speech and songs; their contextual intermediate vocalizations were made up of intermittent singing and speaking. The intermediate vocalizations observed in the present study appear to confirm that singing and speaking are two vocal phenomena that exist along a continuum. They call into question the entire concept of differences between singing and speaking both acoustically and contextually. These intermediate vocalizations offer a rich account of the linguistic and musical development of a child; they suggest that while first spoken language appears to affect vocal development, a child's non-speech auditory environment is also crucial to the understanding of her vocal behaviours.

description: Improvements include corrections for flow expansion, unsteady aerodynamic effects, and flow curvature for the modeling of CN and CT of a 2D VAWT operating under steady inflow conditions for λ = 2, 3 and 4. Results show significant improvement with respect to the classical version of the DMST model, whilst the model is still based on BEM theory and thus some of the main limitations remain. Some further improvements would be necessary before the results can be compared against those produced by the Actuator Cylinder model, most notably the pressure recovery assumption.

description: Humanity has a mix of overlapping goals that relate to science (and more broadly, wissenschaft). We seek new knowledge for its own purpose as well as for its potential solution to both detailed and general problems, situations, and crises. And we want to be able to verify (or disprove) such knowledge (reproducibility), then build on it (reuse), as simply and as cost-effectively as possible. In this talk, I will focus on knowledge captured in research software, which can be both read, executed, and extended. Specifically, we have developed a new set of FAIR (findable, accessible, interoperable, and reusable) Principles for Research Software, which serve an overlapping purpose with open science. This talk will incude: the role of software in research, the FAIR for Research Software Principles, the community that developed them, the next steps in their implementation, and systematic challenges that need to be addressed for software to be more FAIR and for it to better help meet humanity's science goals.

description: Decay of the inflaton or moduli which dominated the energy density of the universe at early times leads to a matter to radiation transition epoch. We consider non-thermal sterile dark matter particles produced as decay product during such transitions. The particles have a characteristic energy distribution - that associated with decays taking place in a matter dominated universe evolving to radiation domination. We primarily focus on the case when the particles are hot dark matter, and study their effects on the Cosmic Microwave Background (CMB) and Large Scale Structure (LSS), explicitly taking into account their non-thermal momentum distribution. Our results for CMB angular power and linear matter power spectra reveal interesting features - such as an order of magnitude higher values of hot dark matter mass in comparison to the thermal case being consistent with the present data. We observe that this is related to the fact that $ΔN_{\rm eff}$ and the hot DM energy density can be independent of each other unlike the case of thermal or non-resonantly produced sterile hot DM. We also find features in the CMB at low $\ell$ angular power potentially related to supersonic transmission of hot dark matter through the photon-baryon plasma.

description: The random oracle model (ROM) enjoys widespread popularity, mostly because it tends to allow for tight and conceptually simple proofs where provable security in the standard model is elusive or costly. While being the adequate replacement of the ROM in the post-quantum security setting, the quantum-accessible random oracle model (QROM) has thus far failed to provide these advantages in many settings. In this work, we focus on adaptive reprogrammability, a feature of the ROM enabling tight and simple proofs in many settings. We show that the straightforward quantum-accessible generalization of adaptive reprogramming is feasible by proving a bound on the adversarial advantage in distinguishing whether a random oracle has been reprogrammed or not. We show that our bound is tight by providing a matching attack. We go on to demonstrate that our technique recovers the mentioned advantages of the ROM in three QROM applications: 1) We give a tighter proof of security of the message compression routine as used by XMSS. 2) We show that the standard ROM proof of chosen-message security for Fiat-Shamir signatures can be lifted to the QROM, straightforwardly, achieving a tighter reduction than previously known. 3) We give the first QROM proof of security against fault injection and nonce attacks for the hedged Fiat-Shamir transform.

Elementary teachers’ expressed beliefs and observed practices of music education in Vancouver and Hong Kong : a descriptive, exploratory study
Creators: name: Wong, Marina Wai-Yee
Publisher: name: University of British Columbia
Year: 2009

description: The aim of this study was to document the expressed beliefs and observed practices of elementary school teachers involved in music instruction in Vancouver and Hong Kong. It is important to understand beliefs and value systems of teachers since they form the basis for their educational practices. These beliefs are shaped by various contextual factors in a society. The music of a society is one such factor that constitutes both cultural and educational practices in that society. Therefore a cross-cultural, comparative study concerned with music education was undertaken so as to better understand the underlying contextual factors that shape teachers' overall understandings and practices of teaching music in the elementary schools. The present investigation is the only study of this kind to date. This study was designed as a qualitative multiple-case study, including five cases in Vancouver and five cases in Hong Kong. The tools for data collection were in-depth interviews and repeated classroom observations. The results of this study suggest that teachers' expressed beliefs and their classroom practices about music education are informed by the following major factors: (1) teachers' personal experiences, (2) social and cultural factors of the societies in which they live, and (3) the music curriculum as set by the school systems. Furthermore, these results shed light on ways in which music education is implemented in these two cosmopolitan cities and demonstrate interesting interplay of various cultural influences. The findings of this study add to the knowledge of Western and Chinese ideas, especially educational thoughts and music education, through presentations and analysis of beliefs and classroom practices of teachers from these two cultures.

Quantum acceleration by an ancillary system in non-Markovian environments

description: We study the effect of an ancillary system on the quantum speed limit time in different non-Markovian environments. Through employing an ancillary system coupled with the quantum system of interest via hopping interaction and investigating the cases that both the quantum system and ancillary system interact with their independent/common environment, and the case that only the system of interest interacts with the environment, we find that the quantum speed limit time will become shorter with enhancing the interaction between the system and environment and show periodic oscillation phenomena along with the hopping interaction between the quantum system and ancillary system increasing. The results indicate that the hopping interaction with the ancillary system and the structure of environment determine the degree of which the evolution of the quantum system can be accelerated.

description: Context: A census of faint and tiny star forming complexes at high redshift is key to improving our understanding of reionizing sources, galaxy growth and the formation of globular clusters. Aims: We present the MUSE Deep Lensed Field (MDLF) program. Methods: We describe Deep MUSE observations of 17.1 hours integration on a single pointing over the Hubble Frontier Field galaxy cluster MACS~J0416. Results: We confirm spectroscopic redshifts for all 136 multiple images of 48 source galaxies at 0.910 for individual objects down to de-lensed magnitude 28-30 suggesting that they are common in such faint sources. Conclusions:Deep MUSE observations, in combination with existing HST imaging, allowed us to:(1) confirm redshifts for extremely faint high-z sources;(2) peer into their internal clumps (down to 100-200 pc scale);(3) in some cases break down such clumps into bound star clusters (<20 pc scale);(4) double the number of constraints for the lens model,reaching an unprecedented set of 182 bona-fide multiple images and confirming up to 213 galaxy cluster members. These results demonstrate the power that JWST and future ELTs will have when combined to study gravitational telescopes.[abridged]

On the evolution of rapidly rotating massive white dwarfs towards supernovae or collapses
Creators: name: Yoon, Sung-Chul
name: Langer, Norbert
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A recent study by Yoon & Langer (2004a) indicated that the inner cores of rapidly accreting (Mdot > 10^{-7} M_sun/yr) CO white dwarfs may rotate differentially, with a shear rate near the threshold value for the onset of the dynamical shear instability. Such differentially rotating white dwarfs obtain critical masses for thermonuclear explosion or electron-capture induced collapse which significantly exceed the canonical Chandrasekhar limit. Here, we construct two-dimensional differentially rotating white dwarf models with rotation laws resembling those of the one-dimensional models of Yoon & Langer (2004a). We derive analytic relations between the white dwarf mass, its angular momentum, and its rotational-, gravitational- and binding energy. We show that these relations are applicable for a wide range of angular velocity profiles, including solid body rotation. We demonstrate that pre-explosion and pre-collapse conditions of both, rigidly and differentially rotating white dwarfs are well established by the present work, which may facilitate future multi-dimensional simulations of Type Ia supernova explosions and studies of the formation of millisecond pulsars and gamma-ray bursts from collapsing white dwarfs.Our results lead us to suggest various possible evolutionary scenarios for progenitors of Type Ia supernovae, leading to a new paradigm of a variable mass of exploding white dwarfs, at values well above the classical Chandrasekhar mass. Based on our 2D-models, we argue for the supernova peak brightness being proportional to the white dwarf mass, which could explain various aspects of the diversity of Type Ia supernovae, such as their variation in brightness, the dependence of their mean luminosity on the host galaxy type, and the weak correlation between ejecta velocity and peak brightness.

The local trace function for super-wavelets

Publisher: name: arXiv
Year: 2005
Subjects: subject: Functional Analysis (math.FA)
subject: FOS: Mathematics

description: We define an affine structure on $\ltwor\oplus...\oplus\ltwor$ and, following some ideas developed in \cite{Dut1}, we construct a local trace function for this situation. This trace function is a complete invariant for a shift invariant subspace and it has a variety of properties which make it easily computable. The local trace is then used to give a characterization of super-wavelets and to analyze their multiplicity function, dimension function and spectral function. The "$n\times$" oversampling result of Chui and Shi \cite{CS} is refined to produce super-wavelets.
