description: In environments with high dense neutrino gases, such as in core-collapse supernovae, the neutrinos can experience collective neutrino oscillation due to their self-interactions. In particular, fast flavor conversion driven by the crossings in the neutrino angular distribution can affect explosion mechanism, nucleosynthesis, and neutrino observation. We perform the numerical computation of nonlinear flavor evolution on the neutrino angular distribution with tiny crossings expected to be generated in the preshock region. We demonstrate that the fast instability is triggered and a cascade develops under a realistic three-flavor model considering muon production and weak magnetism in the SN dynamics. The tiny crossing excites specific spatial modes, and then the flavor instability propagates into other modes which otherwise remain stable due to the nonlinear effects. Our results indicate that fast flavor conversion can rise in the preshock region and have a sufficient impact on the flavor contents.

description: In this paper, we establish Galois theory for partial differential systems defined over formally real differential fields with a real closed field of constants and over formally $p$-adic differential fields with a $p$-adically closed field of constants. For an integrable partial differential system defined over such a field, we prove that there exists a formally real (resp. formally $p$-adic) Picard-Vessiot extension. Moreover, we obtain a uniqueness result for this Picard-Vessiot extension. We give an adequate definition of the Galois differential group and obtain a Galois fundamental theorem in this setting. We apply the obtained Galois correspondence to characterise formally real Liouvillian extensions of real partial differential fields with a real closed field of constants by means of split solvable linear algebraic groups. We present some examples of real dynamical systems and indicate some possibilities of further development of algebraic methods in real dynamical systems.

description: In distinction to the Neumann case the squeezing limit of a Dirichlet network leads in the threshold region generically to a quantum graph with disconnected edges, exceptions may come from threshold resonances. Our main point in this paper is to show that modifying locally the geometry we can achieve in the limit a nontrivial coupling between the edges including, in particular, the class of $δ$-type boundary conditions. We work out an illustration of this claim in the simplest case when a bent waveguide is squeezed.

A canonical transformation theory from extended normal ordering

description: The Canonical Transformation theory of Yanai and Chan [J. Chem. Phys. 124, 194106 (2006)] provides a rigorously size-extensive description of dynamical correlation in multireference problems. Here we describe a new formulation of the theory based on the extended normal ordering procedure of Mukherjee and Kutzelnigg [J. Chem. Phys. 107, 432 (1997)]. On studies of the water, nitrogen, and iron-oxide potential energy curves, the Linearised Canonical Transformation Singles and Doubles theory is competitive in accuracy with some of the best multireference methods, such as the Multireference Averaged Coupled Pair Functional, while computational timings (in the case of the iron-oxide molecule) are two-three orders of magnitude faster and comparable to those of Complete Active Space Second-Order Perturbation Theory. The results presented here are greatly improved both in accuracy and in cost over our earlier study as the result of a new numerical algorithm for solving the amplitude equations.

description: We present a new tensor network algorithm for calculating the partition function of interacting quantum field theories in 2 dimensions. It is based on the Tensor Renormalization Group (TRG) protocol, adapted to operate entirely at the level of fields. This strategy was applied in Ref.[1] to the much simpler case of a free boson, obtaining an excellent performance. Here we include an arbitrary self-interaction and treat it in the context of perturbation theory. A real space analogue of the Wilsonian effective action and its expansion in Feynman graphs is proposed. Using a $λϕ^4$ theory for benchmark, we evaluate the order $λ$ correction to the free energy. The results show a fast convergence with the bond dimension, implying that our algorithm captures well the effect of interaction on entanglement.

description: A two-staged, uniaxial magnetoresistive effect has been discovered in SrCo6O11 having a layered hexagonal structure. Conduction electrons and localized Ising spins are in different sublattices but their interpenetration makes the conduction electrons sensitively pick up the stepwise field-dependence of magnetization. The stepwise field-dependence suggests two competitive interlayer interactions between ferromagnetic Ising-spin layers, i.e., a ferromagnetic nearest-layer interaction and an antiferromagnetic next-nearest-layer interaction. This oxide offers a unique opportunity to study nontrivial interplay between conduction electrons and Ising spins, the coupling of which can be finely controlled by a magnetic field of a few Tesla.

description: We consider a problem of stability of a membrane of an infinite span and a finite chord length, submerged in a uniform flow of finite depth with free surface. In the shallow water approximation, Nemtsov (1985) has shown that an infinite-chord membrane is susceptible to flutter instability due to excitation of long gravity waves on the free surface if the velocity of the flow exceeds the phase velocity of the waves and related this phenomenon with the anomalous Doppler effect. In the present work we derive a full nonlinear eigenvalue problem for an integro-differential equation for the finite-chord Nemtsov membrane in the finite-depth flow. In the shallow- and deep water limits we develop a perturbation theory in the small added mass ratio parameter acting as an effective dissipation, to find explicit analytical expressions for the frequencies and the growth rates of the membrane modes coupled to the surface waves. We find an intricate pattern of instability pockets in the parameter space and describe it analytically. The case of an arbitrary depth flow with free surface requires numerical solution of a new non-polynomial nonlinear eigenvalue problem. We propose an original approach combining methods of complex analysis and residue calculus, Galerkin discretization, Newton method and parallelization techniques implemented in MATLAB to produce high-accuracy stability diagrams within an unprecedentedly wide range of system's parameters. We believe that the Nemtsov membrane plays the same paradigmatic role for understanding radiation-induced instabilities as the Lamb oscillator coupled to a string has played for understanding radiation damping.

description: We analyze five epochs of Spitzer Space Telescope/Infrared Array Camera (IRAC) observations of the nearby spiral galaxy M33. Each epoch covered nearly a square degree at 3.6, 4.5, and 8.0 microns. The point source catalog from the full dataset contains 37,650 stars. The stars have luminosities characteristic of the asymptotic giant branch and can be separated into oxygen-rich and carbon-rich populations by their [3.6] - [4.5] colors. The [3.6] - [8.0] colors indicate that over 80% of the stars detected at 8.0 microns have dust shells. Photometric comparison of epochs using conservative criteria yields a catalog of 2,923 variable stars. These variables are most likely long-period variables amidst an evolved stellar population. At least one-third of the identified carbon stars are variable.

description: Gaia provided the largest-ever catalogue of white dwarf stars. We use this catalogue, along with the third public data release of the Zwicky Transient Facility (ZTF), to identify new eclipsing white dwarf binaries. Our method exploits light curve statistics and the Box Least Squares algorithm to detect periodic light curve variability. The search revealed 18 new binaries, of which 17 are eclipsing. We use the position in the Gaia H-R diagram to classify these binaries and find that the majority of these white dwarfs have main sequence companions. We identify one system as a candidate eclipsing white dwarf--brown dwarf binary and a further two as extremely low mass (ELM) white dwarf binaries. We also provide identification spectroscopy for 17 of our 18 binaries. Running our search method on mock light curves with real ZTF sampling, we estimate our efficiency of detecting objects with light curves similar to the ones of the newly discovered binaries. Many more binaries are to be found in the ZTF footprint as the data releases grow, so our survey is ongoing.

description: We present the first systematic calculations based on the angular-momentum projection of cranked Slater determinants. We propose the Iy --> I scheme, by which one projects the angular momentum I from the 1D cranked state constrained to the average spin projection of =I. Calculations performed for the rotational band in 46Ti show that the AMP Iy --> I scheme offers a natural mechanism for correcting the cranking moment of inertia at low-spins and shifting the terminating state up by ~2 MeV, in accordance with data. We also apply this scheme to high-spin states near the band termination in A~44 nuclei, and compare results thereof with experimental data, shell-model calculations, and results of the approximate analytical symmetry-restoration method proposed previously.

description: White dwarfs, the most abundant stellar remnants, provide a promising means of probing dark matter (DM) interactions, complimentary to terrestrial searches. The scattering of dark matter from stellar constituents leads to gravitational capture, with important observational consequences. In particular, white dwarf heating occurs due to the energy transfer in the dark matter capture and thermalisation processes, and the subsequent annihilation of captured dark matter. We consider the capture of dark matter by scattering on either the ion or the degenerate electron component of white dwarfs. For ions, we account for the stellar structure, the star opacity, realistic nuclear form factors that go beyond the simple Helm approach, and finite temperature effects pertinent to sub-GeV dark matter. Electrons are treated as relativistic, degenerate targets, with Pauli blocking, finite temperature and multiple scattering effects all taken into account. We also estimate the dark matter evaporation rate. The DM-nucleon/electron scattering cross sections can be constrained by comparing the heating rate due to dark matter capture with observations of cold white dwarfs in dark matter-rich environments. We apply this technique to observations of old white dwarfs in the globular cluster Messier 4, which we assume to be located in a DM subhalo. For DM-nucleon scattering, we find that white dwarfs can probe the sub-GeV mass range inaccessible to direct detection searches, with the low mass reach limited only by either evaporation or dominant DM annihilation to neutrinos, and can be competitive with direct detection in the $1-10^4$ GeV range. White dwarf limits on dark matter-electron scattering are found to outperform current electron recoil experiments over the full mass range considered, and extend well beyond the $\sim 10$ GeV mass regime where the sensitivity of electron recoil experiments is reduced.

description: This report presents the BigDataGrapes project vision and ambition and summarises the project’s achievements. Its target audience comprises representatives of external interested communities as well as the general public. The document summarizes the technical and implementation details of the BigDataGrapes infrastructure, describes the technical choices and the rationale behind them, and discusses the research and scientific particularities faced by each of the BigDataGrapes pilots. More specifically, the document establishes the main objectives of the BigDataGrapes project and summarizes the core outcomes of the five pilot communities represented in the project. Based on these two axes, the technical advancements achieved during the reporting period are contextualised and discussed at a high level. Finally, the report concludes with the presentation of the BigDataGrapes platform and the BigDataGrapes Data Market Place. The document is structured as follows. Chapter 1 provides an introduction to the main issues tackled by the BigDataGrapes project, whereas Chapter 2 provides an overview of the use cases with details on the methodology followed in order to define them and associate them with BigDataGrapes pilots. Chapter 3 identifies the progress and results of each of the five selected pilots, while Chapter 4 describes the technical advancements of the project and the BigDataGrapes Platform. Chapter 5 presents the BigDataGrapes Data Market Place providing the necessary proof in action that grapevine-powered data assets are shared and exchanged in interoperable formats and versions, by companies and organisations responsible for them. The last Chapter, discusses the conclusions of the deliverable. Finally, in the annexes we report the best practices for using the BigDataGrapes platform and the GaCoVi usage instruction. All the necessary components to set up an instance of the Big Data Platform are available in the projects Docker hub and can be deployed easily at any infrastructure. The use of dockers is straightforward so in this section, we are describing how one can set up and deploy an instance of the Big Data Platform for a specific use case: collecting and processing food safety incidents that are announced by National Authorities all around the world.

Characterization of the promoter in a human B19 parvovirus
Creators: name: Blundell, Matthew Charles
Publisher: name: University of British Columbia
Year: 2010

description: The nucleotide sequence of the B19-Wi isolate of an autonomous human parvovirus was determined and compared with the sequence of the closely related isolate, B19-Au. The B19-Wi genome was similar to the B19-Au genome, as shown from DNA sequence analyses. It had been previously suggested from the sequence of the B19-Au genome, that the termini may be imperfect inverted terminal repeats. The additional sequence present on the right-hand terminus of B19-Wi supported that supposition. The hairpin termini of the B19 genome were of the same type as those found in adeno-associated parvoviruses, and suggested B19 may be more closely related to AAV viruses than to the autonomous parvoviruses. In vitro transcription with HeLa nuclear extracts using B19-Wi DNA identified a single active RNA polymerase II promoter between map unit 5 and 6. A single promoter was unique; all other parvoviruses characterized to date have two or more active promoters. A series of ordered deletions, prepared in the region upstream of the initiation site of the promoter, indicated that multiple cis-activating motifs were required to maximize in vitro transcription. A transcription factor in HeLa cells specifically bound to and protected a GC rich sequence or GC-box upstream of the promoter, as shown by gel-shift competition assays, and DNAse I and DMS footprinting assays. The protected GC-box had the consensus sequence of a high affinity binding site for the trans-activating factor SP1. The GC-box also formed the distal element of a tandem SPl-like motif, 21 bp upstream of the active TATA box. Synthetic oligonucleotides containing the GC-box specifically bound a HeLa factor and also depressed in vitro transcription from the B19 promoter when added as a competitor. Although not conclusive, binding of the HeLa factor may be inhibited by methylation of a cytosine residue within the GC-box. In vitro transcriptional activity decreased when the GC-box upstream of the B19 promoter was modified by site specific mutagenesis. Preliminary identification of other cis-activating motifs, which include two sequences recognized by factors that are functional both in transcription and replication, suggested that the B19 promoter is a complex regulatory region.

description: We present a detailed analysis of the dynamics of Bloch oscillations of Bose-Einstein condensates in disordered lattice potentials. Due to the disorder and the interparticle interactions these oscillations undergo a dephasing, reflected in a damping of the center of mass oscillations, which should be observable under realistic experimental conditions. The interplay between interactions and disorder is far from trivial, ranging from an interaction-enhanced damping due to modulational instability for strong interactions, to an interaction-reduced damping due to a dynamical screening of the disorder potential.

description: Irving Janis’s concept of ‘groupthink’, the idea that a collective desire for consensus overrides the realistic appraisals of alternatives and leads to poor group decision making, is a staple of social science textbooks. Despite gaining little support in empirical studies, Janis’s eight symptoms of groupthink remains a popular framework. What has been forgotten, however, is that nearly 20 years before Janis’s supposed invention, groupthink was coined by social critic William H Whyte, author of one of the 1950s, most influential books on management. Adding to the growing interest in a historical turn in Management and Organization Studies, we investigate how and why Whyte’s groupthink was over-written by a history that found Janis’s ideas more useful, and outline how recovering Whyte can add value to our thinking now.

This is in the spirit of the Bochi-Mane dichotomy for area-preserving diffeomorphisms on compact surfaces and its continuous-time version for 3-dimensional volume-preserving flows.

Origin of ferroelectric domain wall alignment with surface trenches in ultrathin films

description: Engraving trenches on the surfaces of ultrathin ferroelectric (FE) films and superlattices promises control over the orientation and direction of FE domain walls (DWs). Through exploiting the phenomenon of DW-surface trench (ST) parallel alignment, systems where DWs are known for becoming electrical conductors could now become useful nanocircuits using only standard lithographical techniques. Despite this clear application, the microscopic mechanism responsible for the alignment phenomenon has remained elusive. Using ultrathin PbTiO$_3$ films as a model system, we explore this mechanism with large scale density functional theory simulations on as many as 5,136 atoms. Although we expect multiple contributing factors, we show that parallel DW-ST alignment can be well explained by this configuration giving rise to an arrangement of electric dipole moments which best restore polar continuity to the film. These moments preserve the polar texture of the pristine film, thus minimizing ST-induced depolarizing fields. Given the generality of this mechanism, we suggest that STs could be used to engineer other exotic polar textures in a variety of FE nanostructures as supported by the appearance of ST-induced polar cycloidal modulations in this letter. Our simulations also support experimental observations of ST-induced negative strains which have been suggested to play a role in the alignment mechanism.

description: The $D {\bar D}^*$ scattering amplitude and the production of the final states $π^+ π^- J/ψ$ and $π^+ π^- π^0 J/ψ$ near the $D^0 {\bar D}^{*0}$ threshold are discussed following the recent suggestion that the observed peaks X(3872) and X(3875) in the decays $B \to X K$ are due to a virtual state $X$ in the $D^0 {\bar D}^{*0}$ channel. The strong interaction is treated using the small interaction radius approximation. It is shown that the mass difference between the charged and neutral $D^{(*)}$ mesons results in a distinctive behavior of the relevant isotopic amplitudes. In particular, the shape of the peak in the $π^+ π^- J/ψ$ channel should be significantly narrower than in the $π^+ π^- π^0 J/ψ$ channel, which property can be used for an experimental test of the virtual state hypothesis.

description: R E S U M OO objetivo central deste trabalho é avaliar a disponibilidade de informações sobre a quantificação de carbono na restauração florestal. Especificamente, buscamos responder: (i) Com que frequência a quantificação de carbono em áreas de restauração florestal têm sido alvo de estudos nos últimos anos?; (ii) Quais são os países que mais publicam?; (iii) Quais são as revistas e áreas de pesquisa mais frequentes?; (iv) Qual é o método de restauração mais utilizado e a vegetação mais frequente?; (v) Qual é o software mais usado?; (vi) Qual é o satélite e a metodologia mais predominante? Após a triagem dos dados, apenas 38 estudos foram considerados nas análises deste trabalho. A maioria dos trabalhos (n=15) foram publicados por autores da China, Alemanha (n=4) e USA (n=4). O ano com mais publicações sobre o tema foi 2021 (n=8). As revistas que obtiveram maior número de publicações foram Environmental Research Letters, Forest Ecology and Management e Remote Sensing, com 6 artigos publicados cada uma. No que se refere às áreas de pesquisa, Environmental Sciences (n=16), Biodiversity Conservation, Ecology e Forestry (n=4) obtiveram maior frequência nos resultados de pesquisa. A metodologia de restauração mais citada foi a de Reflorestamento (n=17). O ArcGIS (n=8) e o satélite Landsat (n-17), respectivamente, foram os softwares e os satélites mais utilizados nos artigos. A floresta subtropical (n=7) e a floresta boreal (n=7) apareceram com maior frequência nos trabalhos. A metodologia mais usada foi modelagem (n=13), seguida por classificação supervisionada (n=5). O continente asiático (n=24) foi o lugar mais estudado pelos pesquisadores. Os trabalhos acerca do mapeamento de estudos que abordam a quantificação de carbono em áreas de restauração na base de dados Web of Science foram relativamente poucos. Olhando especificamente para a temática da técnica de restauração florestal por semeadura direta, não foi encontrado nenhum artigo que abordasse essa questão. É necessário testar a quantificação de carbono em diversos métodos de restauração florestal.Palavras-Chaves: mudanças climáticas, sensoriamento remoto, estado da arte.

description: We present several cases of optical observations during gamma-ray bursts (GRBs) which resulted in prompt limits but no detection of optical emission. These limits constrain the prompt optical flux densities and the optical brightness relative to the gamma-ray emission. The derived constraints fall within the range of properties observed in GRBs with prompt optical detections, though at the faint end of optical/gamma flux ratios. The presently accessible prompt optical limits do not require a different set of intrinsic or environmental GRB properties, relative to the events with prompt optical detections.

Developmental preschool music education : a proposed rationale, philosophy and 12-week curriculum for 4-year-old children
Creators: name: Prusky, Kathy Ann
Publisher: name: University of British Columbia
Year: 2010

description: Numerous curricula for preschool music education have been developed in the past two decades. For the most part, however, these have not incorporated important evidence from three disciplines which has important implications for how the music education of preschool children should be approached. The first of these is the field of developmental neurobiology, which has provided relevant information concerning early learning and experience. The second is the research pioneered by Jean Piaget, whose insights into cognitive development bear heavily on curriculum planning for preschool music education. The third is research in musical development, which indicates what skills and behaviors can be expected of preschool children in a musical setting. The goal of this thesis is to demonstrate (a) why an understanding of the major findings from these fields is important to the formulation of a music education program for preschool children; and (b) how this understanding can and should impact on the curricular choices made for the musical education of preschool children. To this extent, a series of developmental and musical objectives for the music education of preschool children, specifically 4-year-olds, have been formulated to serve as a theoretical and practical foundation on which to develop and choose musical activities which are appropriate for this age group. The educational and practical value of each of these activities was tested with a group of 4-year-old children during a 12-week study carried out at the University of British Columbia Child Study Center. The activities which adequately demonstrated this value were then organized into a 12-week music curriculum for 4-year-old children. Four conclusions are made in this thesis. The first of these is that music education should begin early in life in order to influence the general learning patterns necessary for the development of musical skill. The second conclusion is that early exposure to music will be most effective when the activities chosen are complex and stimulating and allow for interaction with numerous musical stimuli on a variety of different levels. The third conclusion is that developmentally appropriate musical activities may make an important contribution to the enrichment of the learning environment during the preschool years and may subsequently enhance sensory, motor, verbal and nonverbal, social and creative thinking skills. Finally, it was concluded that preschool music education will be most effective when musical tasks reflect the limitations of children's cognitive development.

description: Judging the readability of text has many important applications, for instance when performing text simplification or when sourcing reading material for language learners. In this paper, we present a 518 participant study which investigates how scrolling behaviour relates to the readability of a text. We make our dataset publicly available and show that (1) there are statistically significant differences in the way readers interact with text depending on the text level, (2) such measures can be used to predict the readability of text, and (3) the background of a reader impacts their reading interactions and the factors contributing to text difficulty.

The targum (1949:Mar. 1 - 1949:Mar. 25)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1949

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.
Evidence for Three Subpopulations of Globular Clusters in the Early-Type Post-Starburst Shell Galaxy AM 0139-655

description: We present deep HST ACS images of the post-starburt shell galaxy AM 0139-655. We find evidence for the presence of three distinct globular cluster subpopulations associated with this galaxy: a centrally concentrated young population (~ 0.4 Gyr), an intermediate age population (~ 1 Gyr) and an old, metal-poor population similar to that seen around normal galaxies. The g-I color distribution of the clusters is bimodal with peaks at 0.85 and 1.35. The redder peak at g-I=1.35 is consistent with the predicted color for an old metal-poor population. The clusters associated with the peak at g-I=0.85 are centrally concentrated and interpreted as a younger and more metal-rich population. We suggest that these clusters have an age of ~ 0.4 Gyr and solar metallicity based on a comparison with population synthesis models. The luminosity function of these "blue" clusters is well represented by a power law. Interestingly, the brightest shell associated with the galaxy harbors some of the youngest clusters observed. This seems to indicate that the same merger event was responsible for the formation of both the shells and the young clusters. The red part of the color distribution contains several very bright clusters, which are not expected for an old, metal-poor population. Furthermore, the luminosity function of the "red" GCs cannot be fit well by either a single gaussian or a single power law. A composite (gaussian + power law) fit to the LF of the red clusters yields both a low rms and very plausible properties for an old population plus an intermediate-age population of GCs. Hence, we suggest that the red clusters in AM 0139-655 consist of two distinct GC subpopulations, one being an old, metal-poor population as seen in normal galaxies and one having formed during a recent dissipative galaxy merger.
