description: We show that a discrete sequence $Λ$ of the complex plane is the union of $n$ interpolating sequences for the Hörmander algebras $A_p$ if and only if the trace of $A_p$ on $Λ$ coincides with the space of functions on $Λ$ for which the divided differences of order $n-1$ are uniformly bounded. The analogous result holds in the unit disk for Korenblum-type algebras.

description: We present a trajectory-based semiclassical calculation of the full counting statistics of quantum transport through chaotic cavities, in the regime of many open channels. Our method to obtain the $m$th moment of the density of transmission eigenvalues requires two correlated sets of $m$ classical trajectories, therefore generalizing previous works on conductance and shot noise. The semiclassical results agree, for all values of $m$, with the corresponding predictions from random matrix theory.

Drift capacity models for modern URM walls for EC8 Part 1
Creators: name: Beyer, Katrin

Publisher: name: Zenodo
Year: 2019

description: This objective of this report was to put forward drift capacity models for the revised Eurocode 8, Part 1 (EC8-Part 1). For this purpose, it reviews the data available on quasi-static cyclic tests on masonry walls in the recently assembled European database for URM walls. Based on this review, it proposes two simple drift capacity models. Both models account for the unit typology. In addition, Model 1 accounts for the failure mode and follows therefore the traditional form for URM drift capacity models. Unlike the current drift capacity model in the current EC8-Part 3 [2], it introduces an axial load ratio limit of 0.3. Walls subjected to higher ALR should be avoided; if this is not possible, it should be assumed that they have only one third of the drift capacity of walls with ALR ≤ 0.3. Note that the idea of an ALR-limit is already included in the German national annex to Eurocode 8 [38] for walls failing in shear. It limits the SD drift capacity of 0.4%, which is specified in the current EC8-Part 3, to walls with an ALR ≤ 0.15. For walls with a larger ALR, the drift capacity is reduced to 0.3%. All files, from the extraction of the data from the data bases to the files for plotting the figures are publicly shared. A file register describing the content of the files is included at the end of each chapter of the report.
An analysis of academic achievement among grades 7 to 11 students in a Northwestern Ontario band-controlled school
Creators: name: Senior, Sharon
Publisher: name: University of British Columbia

description: The main purposes of this study were to determine if there were (a) correlational relationships between academic self—concept (ASC), general self—concept (GSC), attendance, (ATT), socioeconomic status (SES), and academic achievement (AA) among grades 7 to 11 students in a band—controlled school in Northwestern Ontario; and, (b) if academic self—concept, global self—concept, attendance, and socioeconomic status were predictors of academic achievement. The population sample was 70 Native students; 20 in grade 7, 27 in grade 8, 13 in grade 9, 4 in grade 10, and 6 in grade 11. The results showed: (1) significant correlational relationships between (a) ASC and GSC and SC and ATT for the grades 7—9 students; (b) ASC and ATT for the grades 10-11 students; and, (2) academic achievement was not predicted by any of the variables. Future research concerning Native education is suggested.

description: The radio complex Sgr B region is observed with the X-Ray Imaging Spectrometers (XIS) on board Suzaku. This region exhibits diffuse iron lines at 6.4, 6.7 and 6.9 keV, which are K$α$ lines of Fe \emissiontype{I} (neutral iron), Fe\emissiontype{XXV} (He-like iron) and Fe\emissiontype{XXVI} (H-like iron), respectively. The high energy resolving power of the XIS provides the separate maps of the K-shell transition lines from Fe\emissiontype{I} (6.4 keV) and Fe\emissiontype{XXV} (6.7 keV). Although the 6.7 keV line is smoothly distributed over the Sgr B region, a local excess is found near at $(l, b) = (\timeform {0D.61}, \timeform{0D.01})$, possibly a new SNR. The plasma temperature is \textit{kT} $\sim$3 keV and the age is estimated to be around several$\times10^{3}$ years. The 6.4 keV image is clumpy with local excesses nearby Sgr B2 and at $(l, b) = (\timeform{0D.74}, -\timeform{0D.09})$. Like Sgr B2, this excess may be another candidate of an X-ray reflection nebula (XRN).

description: In many economic contexts, agents from a same population team up to better exploit their human capital. In such contexts (often called "roommate matching problems"), stable matchings may fail to exist even when utility is transferable. We show that when each individual has a close substitute, a stable matching can be implemented with minimal policy intervention. Our results shed light on the stability of partnerships on the labor market. Moreover, they imply that the tools crafted in empirical studies of the marriage problem can easily be adapted to many roommate problems.

description: We present the first thermoelectric measurements on pentacene field effect transistors. We report high values of the Seebeck coefficient at room temperature between 240 and 500 micro V/K depending on the dielectric surface treatment. These values are independent of the thickness of the channel and of the applied gate voltage. Two contributions to the Seebeck coefficient are clearly identified: the expected contribution that is dependent on the position of the transport level and reflects the activated character of carrier generation, and an unexpected intrinsic contribution of 265 plus minus 40 micro V/K that is independent of the temperature and the treatment of the oxide surface. This value corresponds to an unusually large lattice vibrational entropy of 3 kB per carrier. We demonstrate that this intrinsic vibrational entropy arises from lattice hardening induced by the presence of the charge-carrier. Our results provide direct evidence of the importance of electronic polarization effects on charge transport in organic molecular semiconductors.

It is shown that, if confronted with current observational data, the results derived when no cosmological constant is present are once again obtained in both cases.

description: We present the next-to-next-to-leading order ($alpha alpha_s^2$) corrections to the first moment of the polarized virtual photon structure function $g_1^gamma(x,Q^2,P^2)$ in the kinematical region $Lambda^2 ll P^2 ll Q^2$, where $-Q^2(-P^2)$ is the mass squared of the probe (target) photon and $Lambda$ is the QCD scale parameter. In order to evaluate the three-loop-level photon matrix element of the flavor singlet axial current, we resort to the Adler-Bardeen theorem for the axial anomaly and we calculate in effect the two-loop diagrams for the photon matrix element of the gluon operator. The $alpha alpha_s^2$ corrections are found to be about 3% of the sum of the leading order ($alpha$) andthe next-to-leading order ($alpha alpha_s$) contributions, when $Q^2=30 sim 100 {rm GeV}^2$and $P^2=3{rm GeV}^2$, and the number of active quark flavors $n_f$ is three to five.

description: We present a system for localizing sound sources in a room with several ad-hoc microphone arrays. Each circular array performs direction of arrival (DOA) estimation independently using commercial software. The DOAs are fed to a fusion center, concatenated, and used to perform the localization based on two proposed methods, which require only few labeled source locations (anchor points) for training. The first proposed method is based on principal component analysis (PCA) of the observed DOA and does not require any knowledge of anchor points. The array cluster can then perform localization on a manifold defined by the PCA of concatenated DOAs over time. The second proposed method performs localization using an affine transformation between the DOA vectors and the room manifold. The PCA has fewer requirements on the training sequence, but is less robust to missing DOAs from one of the arrays. The methods are demonstrated with five IoT 8-microphone circular arrays, placed at unspecified fixed locations in an office. Both the PCA and the affine method can easily map out a rectangle based on a few anchor points with similar accuracy. The proposed methods provide a step towards monitoring activities in a smart home and require little installation effort as the array locations are not needed.

Analyses are made in two ways: by assuming single-mode amplitudes and by generalizing Hirota's direct method for multi-components. We obtain one-solitons of single-peak type in the ferromagnetic, polar and cyclic states, respectively. Moreover, twin-peak type solitons both in the ferromagnetic and the polar state are found.

Lattice dynamics of photoexcited insulators from constrained density-functional perturbation theory

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: We present a constrained density functional perturbation theory scheme for the calculation of structural and harmonic vibrational properties of insulators in the presence of an excited and thermalized electron-hole plasma. The method is ideal to tame ultrafast light induced structural transitions in the regime where the photocarriers thermalize faster than the lattice, the electron-hole recombination time is longer than the phonon period and the photocarrier concentration is large enough to be approximated by an electron-hole plasma. The complete derivation presented here includes total energy, forces and stress tensor, variable cell structural optimization, harmonic vibrational properties and the electron-phonon interaction. We discuss in detail the case of zone center optical phonons not conserving the number of electrons and inducing a Fermi shift in the photo-electron and hole distributions. We validate our implementation by comparing with finite differences in Te and VSe2. By calculating the evolution of the phonon spectrum of Te, Si and GaAs as a function of the fluence of the incoming laser light, we demonstrate that even at low fluences, corresponding to approximately 0.1 photocarriers per cell, the phonon spectrum is substantially modified with respect to the ground state one with new Kohn anomalies appearing and a substantial softening of zone center optical phonons. Our implementation can be efficiently used to detect reversible transient phases and irreversible structural transition induced by ultrafast light absorption.

Low metallicity stars in our Galaxy

description: The advent of m class telescopes has allowed the detailed spectroscopic study of sizeable numbers of extremely metal-poor Galactic stars which are the witnesses of the formation of the early Galaxy. Their chemical composition displays some distinctive trends which should provide a strong constraint on the physical nature of the first generation(s) of stars and on their nucleosynthetic output. I will review recent results in the field following the periodic table, from lithium to uranium and shortly comment on the intriguing classes of Carbon Enhanced Metal Poor (CEMP) stars, for many of which there is no analogue among solar metallicity stars. In spite of these exciting results, the number of known stars of metallicity below [Fe/H]=-3.3 remains quite small and it would be desirable to discover more, both to clearly understand the metal-weak tail of Halo metallicity distribution and to clarify the abundance trends at the lowest metallicities. Most of these extremely rare objects have been discovered by the wide field objective prism surveys, HK survey and Hamburg-ESO survey. In the near future the Sloan Digital Sky Survey and its continuation SEGUE are expected to boost significantly the numbers of known extremely metal poor stars. We are living exciting times but an even more exciting future lies ahead !

description: We present exact results that give insight into how interactions lead to transport and superconductivity in a flat band where the electrons have no kinetic energy. We obtain bounds for the optical spectral weight for flat band superconductors, that lead to upper bounds for the superfluid stiffness and the 2D $T_c$. We focus on on-site attraction $|U|$ on the Lieb lattice with trivial flat bands and on the $π$-flux model with topological flat bands. For trivial flat bands, the low-energy optical spectral weight $\widetilde{D}_\text{low} \leq \widetilde{n} |U| Ω/2$ with $\widetilde{n} = \min\left(n,2-n\right)$, where $n$ is the flat band density and $Ω$ the Marzari-Vanderbilt spread of the Wannier functions (WFs). We also obtain a lower bound involving the quantum metric. For topological flat bands, with an obstruction to localized WFs respecting all symmetries, we again obtain an upper bound for $D_{\rm low}$ linear in $|U|$. We discuss the insights obtained from our bounds by comparing them with mean-field and quantum Monte-Carlo results.

description: We point out that theories describing s-wave collisions of bosonic atoms confined in one- or two-dimensional geometries can be extended to much tighter confinements than previously thought. This is achieved by replacing the scattering length by an energy-dependent scattering length which was already introduced for the calculation of energy levels under 3D confinement. This replacement accurately predicts the position of confinement-induced resonances in strongly confined geometries.

description: This paper considers contact processes with additional voter model dynamics. For such models, results of Lloyd and Sudbury can be applied to find a self-duality, as well as dualities and thinning relations with systems of random walks with annihilation, branching, coalescence, and deaths. We show that similar relations, which are known from the literature for certain interacting SDE's, can be derived as local mean field limits of the relations of Lloyd and Sudbury.

description: The magnetic excitations in Ca1.8Sr0.2RuO4 were studied across the metamagnetic transition and as a function of temperature using inelastic neutron scattering. At low temperature and low magnetic field the magnetic response is dominated by a complex superposition of incommensurate antiferromagnetic fluctuations. Upon increasing the magnetic field across the metamagnetic ransition, paramagnon and finally well-defined magnon scattering is induced, partially suppressing the incommensurate signals. The high-field phase in Ca1.8Sr0.2RuO4 has, therefore, to be considered as an intrinsically ferromagnetic state stabilized by the magnetic field.

Associations between mood states in high-risk infants and later neurodevelopmental outcomes
Creators: name: Pighini Mirabal, Maria J.
Publisher: name: University of British Columbia
Year: 2008

description: This retrospective study examined the possibility of associations between twovariables: "neurodevelopmental outcome" (cerebral palsy, developmental delays and non-handicapped) and "mood states" (fussy/skittish, calm, sunny, and too variable to rate) in a sample of 208 high-risk infants. It was based on the premise that predominantly negative or variable moods (i.e., "fussy/skittish" or "too variable to rate") among high-risk infants might be considered neurobehavioural markers for later neurodevelopmental disabilities,such as cerebral palsy. The main hypothesis of the study expected the two variables to be related, that is, that there would be an overall association between "neurodevelopmental outcome" between the ages of 3 to 8 years and "mood states," at 4 months' corrected age. Should the main hypothesis have been confirmed, four subsequent hypotheses predicted specific associations between the outcome category of cerebral palsy and irritable and labile "mood states," as well as specific associations between the outcome category of developmental delays and irritable and labile "mood states". A chi-square analysis conducted to test the overall association between "neurodevelopmental outcome" and"mood states" showed no association between them. For that reason, specific associations were not tested. Because more sensitive statistical analyses could not be used, some caution is necessary in drawing final conclusions. However, interesting tendencies were observed in the distribution of the ratings of "mood states" among the categories of "neurodevelopmental outcome," which call for further evaluation in the testing of the distribution. Therefore, in spite of the fact that the main research hypothesiswas rejected, the results of the present study suggest the need for additional research. The fact that no significant relationships could be found is an important finding, and suggests the need for prospective longitudinal research on this topic.

description: The Crab nebula was observed with the H.E.S.S. stereoscopic Cherenkov-telescope array between October 2003 and January 2005 for a total of 22.9 hours (after data quality selection). Observations were made with three operational telescopes in late 2003 and with the complete 4 telescope array in January - February 2004 and October 2004 - January 2005. The observations are discussed and used as an example to detail the flux and spectral analysis procedures of H.E.S.S., and to evaluate the systematic uncertainties in H.E.S.S. flux measurements. The flux and spectrum of gamma-rays from the source are calculated on run-by-run and monthly time-scales, and a correction is applied for long-term variations in the detector sensitivity. Comparisons of the measured flux and spectrum over the observation period, along with the results from a number of different analysis procedures are used to estimate systematic uncertainties in the measurements. The energy spectrum is found to follow a power law with an exponential cutoff, with photon index $Γ= 2.39 \pm 0.03\stat$ and cutoff energy $E_{c} = (14.3 \pm 2.1\stat) \textrm{TeV}$ between 440 GeV and 40 TeV. The observed integral flux above 1 TeV is $(2.26 \pm 0.08\stat) \times 10^{-11} cm^{-2} s^{-1}$. The estimated systematic error on the flux measurement is estimated to be 20%, while the estimated systematic error on the spectral slope is 0.1.

description: Transport and non-equilibrium magnetization in monolayers of magnetic molecules subject to a bias voltage are considered. We apply a master-equation approach going beyond the sequential-tunneling approximation to study the Coulomb-blockade regime. While the current is very small in this case, the magnetization shows changes of the order of the saturation magnetization for small variations of the bias voltage. Inelastic cotunneling processes manifest themselves as differential-conductance steps, which are accompanied by much larger changes in the magnetization. In addition, the magnetization in the Coulomb-blockade regime exhibits strong signatures of sequential tunneling processes de-exciting molecular states populated by inelastic cotunneling. We also consider the case of a single molecule, finding that cotunneling processes lead to the occurrence of magnetic sidebands below the Coulomb-blockade threshold. In the context of molecular electronics, we study how additional spin relaxation suppresses the fine structure in transport and magnetization.

description: Στόχος της παρούσας έρευνας είναι να ασχοληθεί με τη μελέτη της αφηγηματικής ικανότητας σε παιδιά προσχολικής ηλικίας με δυσκολίες στο λόγο. Πιο συγκεκριμένα από δείγμα 54 παιδιών, κατόπιν αξιολόγησής τους με το ψυχομετρικό εργαλείο DTLA:P-3 προέκυψαν δύο ομάδες παιδιών. Παιδιά σε επικινδυνότητα για ειδική διαταραχή του λόγου και παιδιά με χαμηλή ανάπτυξη στον λόγο. Στη συνέχεια της έρευνας, τα παιδιά των δύο ομάδων αφηγήθηκαν μια ιστορία με τη βοήθεια εικόνων που τους δόθηκαν. Η αξιολόγηση των ιστοριών των παιδιών έγινε με βάση τα έξι στάδια της αφήγησης του Applebee. Διαπιστώθηκε πως τα παιδιά και των δύο ομάδων παρουσιάζουν δυσκολίες στον αφηγηματικό λόγο. Συγκεκριμένα τα περισσότερα παιδιά ταξινομήθηκαν στα στάδια των ακολουθιών και των πρώιμων αφηγήσεων σύμφωνα με τα έξι στάδια το Applebee. Επίσης, δεν βρέθηκε σημαντική διαφορά των αφηγήσεων των παιδιών των δύο ομάδων, αλλά και κάποια συσχέτιση με το φύλο.
description: The purpose of this study is to investigate narrative skills of preschoolers with language difficulties. In particular, the study sample consisted of 54 preschoolers. The total of the children has been distinguished into two categories, according to the psychometric criterion DTLA-P:3; children at risk for Special Language Impairment and children with low language development. The narrative skills of the two groups were examined through story generation (storytelling). In storytelling children are instructed to compose their own story based on a series of illustrations. Children’s narrations were assessed using the Applebee’s model, in order to discover in which narrative stage, they belonged. The research results showed that both children at risk and children with low language development have difficulties in narrative skills. Furthermore, there are no statistically important differences between the narratives of two groups. Finally, there are also no statistically important differences between gender and the narratives of two groups.

description: Galaxy clusters are hotter and more X-ray luminous than in quiescence while they undergo major mergers, which also transiently increase their strong-lensing efficiency. We use semi-analytic models for both effects to study how cluster dynamics in different dark-energy models affects the X-ray selected cluster population and its strong-lensing optical depth. We find that mergers increase the number of observable X-ray clusters by factors of a few and considerably broaden their redshift distribution. Strong-lensing optical depths are increased by a very similar amount. Quite independent of cosmology, X-ray bright clusters above a flux limit of $10^{-13.5} \mathrm{erg s^{-1} cm^{-2}}$ produce $\sim60%$ of the strong-lensing optical depth, and only $\sim1%$ above a flux limit of $10^{-11.5} \mathrm{erg s^{-1} cm^{-2}}$ if mergers are taken into account.

description: I present an experimental realization of a coherent-feedback control system that was recently proposed for testing basic principles of linear quantum stochastic control theory [M. R. James, H. I. Nurdin and I. R. Petersen, to appear in IEEE Transactions on Automatic Control (2008), arXiv:quant-ph/0703150v2]. For a dynamical plant consisting of an optical ring-resonator, I demonstrate ~ 7 dB broadband disturbance rejection of injected laser signals via all-optical feedback with a tailored dynamic compensator. Comparison of the results with a transfer function model pinpoints critical parameters that determine the coherent-feedback control system's performance.

description: Non-Gaussian continuous variable states play a central role both in the foundations of quantum theory and for emergent quantum technologies. In particular, "cat states", i.e., two-component macroscopic quantum superpositions, embody quantum coherence in an accessible way and can be harnessed for fundamental tests and quantum information tasks alike. Degenerate optical parametric oscillators can naturally produce single-mode cat states and thus represent a promising platform for their realization and harnessing. We show that a dissipative coupling between degenerate optical parametric oscillators extends this to two-mode entangled cat states, i.e., two-mode entangled cat states are naturally produced under such dissipative coupling. While overcoming single-photon loss still represents a major challenge towards the realization of sufficiently pure single-mode cat states in degenerate optical parametric oscillators, we show that the generation of two-mode entangled cat states under such dissipative coupling can then be achieved without additional hurdles. We numerically explore the parameter regime for the successful generation of transient two-mode entangled cat states in two dissipatively coupled degenerate optical parametric oscillators. To certify the cat-state entanglement, we employ a tailored, variance-based entanglement criterion, which can robustly detect cat-state entanglement under realistic conditions.

description: A set of symmetric and asymmetric superlattices with ferromagnetic La0.6Sr0.4MnO3 and ferroelectric 0.7Pb(Mg0.33Nb0.67)O3 0.3(PbTiO3) as the constituting layers were fabricated on LaNiO3 coated (100) oriented LaAlO3 substrates using pulsed laser ablation. The crystallinity, magnetic and ferroelectric properties were studied for all the superlattices. All the superlattice structures exhibited a ferromagnetic behavior over a wide range of temperatures between 10K and 300K, whereas only the asymmetric superlattices exhibited a reasonably good ferroelectric behaviour. Strong influence of an applied magnetic field was observed on the ferroelectric properties of the asymmetric superlattices. Studies were conducted towards understanding the influence of conducting LSMO layers on the electrical responses of the heterostructures. The absence of ferroelectricity in the symmetric superlattice structures has been attributed to their high leakage characteristics. The effect of an applied magnetic field on the ferroelectric properties of the asymmetric superlattices indicated strong influence of the interfaces on the properties. The dominance of the interface on the dielectric response was confirmed by the observed Maxwell Wagner type dielectric relaxation in these heterostructures.

description: Optical spectroscopy in the gas phase is a key tool to elucidate the structure of atoms and molecules and of their interaction with external fields. The line resolution is usually limited by a combination of first-order Doppler broadening due to particle thermal motion and of a short transit time through the excitation beam. For trapped particles, suitable laser cooling techniques can lead to strong confinement (Lamb-Dicke regime, LDR) and thus to optical spectroscopy free of these effects. For non-laser coolable spectroscopy ions, this has so far only been achieved when trapping one or two atomic ions, together with a single laser-coolable atomic ion [1,2]. Here we show that one-photon optical spectroscopy free of Doppler and transit broadening can also be obtained with more easily prepared ensembles of ions, if performed with mid-infrared radiation. We demonstrate the method on molecular ions. We trap approximately 100 molecular hydrogen ions (HD$^{+}$) within a Coulomb cluster of a few thousand laser-cooled atomic ions and perform laser spectroscopy of the fundamental vibrational transition. Transition frequencies were determined with lowest uncertainty of 3.3$\times$10$^{-12}$ fractionally. As an application, we determine the proton-electron mass ratio by matching a precise ab initio calculation with the measured vibrational frequency.

description: We test the property of ultrametricity for the spin glass three-dimensional Edwards-Anderson model in zero magnetic field with numerical simulations up to $20^3$ spins. We find an excellent agreement with the prediction of the mean field theory. Since ultrametricity is not compatible with a trivial structure of the overlap distribution our result contradicts the droplet theory.
