Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: There is a viable vector-tensor gravity (VTG) theory, whose vector field produces repulsive forces leading to important effects. In the background universe, the effect of these forces is an accelerated expansion identical to that produced by vacuum energy (cosmological constant). Here, we prove that another of these effects arises for great enough collapsing masses which lead to Schwarzschild black holes and singularities in general relativity (GR). For these masses, pressure becomes negligible against gravitational attraction and the complete collapse cannot be stopped in the context of GR; however, in VTG, a strong gravitational repulsion could stop the falling of the shells towards the symmetry center. A certain study of a collapsing dust cloud is then developed and, in order to undertake this task, the VTG equations in comoving coordinates are written. In this sense and, as it happens in general relativity for a pressureless dust ball, three different solutions are found. These three situations are analyzed and the problem of the shell crossings is approached. The apparent horizons and trapped surfaces, whose analysis will lead to diverse situations, depending on certain theory characteristic parameter value, are also examined.

description: The similarity theory of stellar structure is used to study the properties of very massive stars when one can neglect all the sources of opacity except for the Thomson scattering. The dimensionless internal structure of such stars is practically independent of the energy generation law. It is shown that the mass-luminosity relation can be approximated by an analytical expression which is virtually universal regarding the chemical composition and energy generation law. A detailed comparison with the Eddington standard model is given. The application of the obtained results to the observations of massive stars is briefly discussed.

description: The properties of a system of n = 3 coupled oscillators with linear terms in the velocities (magnetic terms) depending in two parameters are studied. We proved the existence of a bi-Hamiltonian structure arising from a non-symplectic symmetry, as well the existence of master symmetries and additional integrals of motion (weak superintegrability) for certain particular values of the parameters.

description: Using a directional spherical wavelet analysis we detect the integrated Sachs-Wolfe (ISW) effect, indicated by a positive correlation between the Wilkinson Microwave Anisotropy Probe (WMAP) and NRAO VLA Sky Survey (NVSS) data, at the 3.9 sigma level. In a flat universe the detection of the ISW effect provides direct and independent evidence for dark energy. Moreover, we use our detection to constrain the dark energy density Omega_Lambda. We obtain estimates for Omega_Lambda consistent with other analysis techniques and data sets and rule out a zero cosmological constant at greater than 99% significance.

description: [abridged] A "missing data" algorithm is developed to model (ie, reconstruct) the three-dimensional velocity distribution function of a sample of stars using data (velocity measurements) every one of which has one dimension unmeasured (the radial direction). It also accounts for covariant measurement uncertainties on the tangential velocity components. The algorithm is applied to tangential velocities measured in a kinematically unbiased sample of 11,865 stars taken from the Hipparcos catalog. The local stellar velocity distribution function of each of a set of 20 color-selected subsamples is modeled as a mixture of two three-dimensional Gaussian ellipsoids of arbitrary relative responsibility. In the fitting, one Gaussian (the "halo") is fixed at the known mean velocity and velocity variance tensor of the Galaxy halo, and the other (the "disk") is allowed to take arbitrary mean and arbitrary variance tensor. The mean and variance tensor (commonly the "velocity ellipsoid") of the disk velocity distribution are both found to be strong functions of stellar color, with long-lived populations showing larger velocity dispersion, slower mean rotation velocity, and smaller vertex deviation than short-lived populations. The local standard of rest (LSR) is inferred in the usual way and the Sun's motion relative to the LSR is found to be (U,V,W)_{\odot}=(10.1,4.0,6.7)+/-(0.5,0.8,0.2) km/s. Artificial data sets are made and analyzed, with the same error properties as the Hipparcos data, to demonstrate that the analysis is unbiased. The results are shown to be insensitive to the assumption that the velocity distributions are Gaussian.

Intestinal calcium transport in the chicken
Creators: name: Bhatti, Mohammad Suleman
Publisher: name: University of British Columbia
Year: 2009

description: The regulation of intestinal calcium transport is a subject of continuing controversy. Most investigations on this subject have involved use of the laboratory rat or layer-type chicken. The research reported in this thesis was conducted in 0- to 21-d-old rapidly growing broiler cockerels, mainly using in situ intestinal loop preparations. Intralumenal test solutions typically containing 75 mM each of ⁴CaCl₂ and ³H-mannitol were used to delineate the cellular and paracellular fractions of in situ calcium transport. At this concentration, about 75 to 85 % of calcium transport from duodenal loops was shown to occur via the paracellular pathway. In contrast, calcium transport from distal ileal loops occurred entirely via the paracellular pathway and was not influenced by l,25-(OH)₂D₃ administration. Further, mannitol disappearance from in situ intestinal loops was not affected by vitamin D-dependent mechanisms. In balance studies, calcium absorption in intact birds occurred primarily by a nonsaturable process when solubility was not a limiting factor, thereby supporting the in situ data that showed the predominance of paracellular calcium transport. Mannitol absorption and secretion were demonstrated to be nonsaturable suggesting both occur by paracellular mechanisms. The efficiency of paracellular transport tended to remain unchanged with age, in the duodenal, distal jejunal, and distal ileal loops of 0- to 14-d-old broiler chicks. The efficiency was 1.5 to 2 fold greater in the duodenal compared to the distal jejunal or distal ileal loops. The capacity of paracellular transport in these intestinal regions increased with age. It is concluded that when intralumenal calcium concentration is high and the solubility is not a limiting factor, intestinal calcium transport, both in in situ loops and in intact rapidly growing young broiler cockerels occurs largely by a paracellular process, which can take place in the absence of vitamin D.

description: Through the discovery of luxury bronze vessels of Etruscan and in lesser numbers of Greek origin, scholarship had already realized around the middle of the 19th century that there must exist cultural contacts between the Mediterranean civilisations and the Celtic world in western Central Europe. Subsequent studies verified that the different groups comprising the Hallstatt culture were cross linked with the cultures in Upper and Central Italy; and that it was not only the Etruscans who involved their products in this exchange of goods, but also the Upper Italian cultures and the Picenes in eastern Central Italy, who both trafficked their products into Central Europe. It is noticeable that in the region northwest of the Alps it is mainly dress accessories and bronze vessels, which belong to sympotic activities for drinking wine, that were adopted. In contrast in the Eastern Hallstatt area weapons too were taken up. Not only luxury goods were involved, but also simple objects like fibulae, which made a much deeper impact in Central Europe. The adoption of early fibula-types and of figural art on metal vessels in the Alps and in Slovenia shows that the people in this area were earlier disposed to integrate southern influences in their own cultures, just as happened in the region north of the Alps. Here though the inhabitants in the 8th and 7th centuries BC were slower at accepting these innovations; only a little before 600 BC did they adopt the fibula-requiring costume in the upper Italian and inner alpine fashion. In the case of the figural art, the culture groups north of the Alps were much more conservative; not until the beginning of the La Tène-period in the 5th century BC did they accept something of figural art. In all these cases no "Mediterranization" of the central European cultures ever took place, but rather the contacts and the acquisition of prestige goods from the south promoted the development of powerful local elites, as we have recognized them in Styria, in south-western Germany and north-eastern France.

description: Dynamical capture is a possible formation channel for BBH mergers leading to highly eccentric merger dynamics and to gravitational wave (GW) signals that are morphologically different from those of quasi-circular mergers. The future detection of these mergers by ground-based or space-based GW interferometers can provide invaluable insights on astrophysical black holes, but it requires precise predictions and dedicated waveform models for the analysis. We present a state-of-the-art effective-one-body (EOB) model for the multipolar merger-ringdown waveform from dynamical capture black-hole mergers with arbitrary mass-ratio and nonprecessing spins. The model relies on analytical descriptions of the radiation reaction and waveform along generic orbits that are obtained by incorporating generic Newtonian prefactors in the expressions used in the quasi-circular case. It provides a tool for generating waveforms for generic binary black hole coalescences and for GW data analysis. We demonstrate that the model reliably accounts for the rich phenomenology of dynamical captures, from direct plunge to successive close encounters up to merger. The parameter space is fully characterized in terms of the initial energy and angular momentum. Our model reproduces to few percent the scattering angle from ten equal-mass, nonspinning, hyperbolic encounter numerical-relativity (NR) simulations. The agreement can be further improved to the by incorporating 6PN-results in one of the EOB potentials and tuning currently unknown analytical parameters. Our results suggest that NR simulations of hyperbolic encounters (and dynamical captures) can be used to inform EOB waveform models for generic BBH mergers/encounters for present and future GW detectors.

description: Quarks come in three colors and have electric charges in multiples of one-third. There are also three families of quarks and leptons. Whereas the first two properties can be understood in terms of unification symmetries such as SU(5), SO(10), or E_6, why there should only be three families remains a mystery. I propose how all three properties involving the number three are connected in a fivefold application of the gauge symmetry SU(3).

description: The JOREK extended magneto-hydrodynamic (MHD) code is a widely used simulation code for studying the non-linear dynamics of large-scale instabilities in divertor tokamak plasmas. Due to the large scale-separation intrinsic to these phenomena both in space and time, the computational costs for simulations in realistic geometry and with realistic parameters can be very high, motivating the investment of considerable effort for optimization. In this article, a set of developments regarding the JOREK solver and preconditioner is described, which lead to overall significant benefits for large production simulations. This comprises in particular enhanced convergence in highly non-linear scenarios and a general reduction of memory consumption and computational costs. The developments include faster construction of preconditioner matrices, a domain decomposition of preconditioning matrices for solver libraries that can handle distributed matrices, interfaces for additional solver libraries, an option to use matrix compression methods, and the implementation of a complex solver interface for the preconditioner. The most significant development presented consists in a generalization of the physics based preconditioner to "mode groups", which allows to account for the dominant interactions between toroidal Fourier modes in highly non-linear simulations. At the cost of a moderate increase of memory consumption, the technique can strongly enhance convergence in suitable cases allowing to use significantly larger time steps. For all developments, benchmarks based on typical simulation cases demonstrate the resulting improvements.

description: We present the results of a spectroscopic campaign on eclipsing binaries with long orbital period (P = 20 - 75 d) carried out with the CHIRON spectrograph. Physical and orbital solutions for seven systems were derived from the V-band, and I-band ASAS, WASP, and TESS photometry, while radial velocities were calculated from high quality optical spectra using a two-dimensional cross-correlation technique. The atmospheric parameters of the stars have been determined from the separated spectra. Most of our targets are composed of evolved stars (sub-giants or red giants) but two systems show components in different phases of evolution and one possible merger. For four binaries the masses and radii of the components were obtained with precision better than 3%. These objects provide very valuable information on stellar evolution.

If, furthermore, $k$ is greater than a second threshold $m_2\ge m_1$, the normalized mean inverse population is at most $1/(k-m_2)$. We express $m_1$ and $m_2$ as explicit functionals of the reproducing distribution, we discuss some analogues for discrete time branching processes and link these results to the behavior of random products involving i.i.d. nonnegative sums.

The effects of aluminum on cytoplasmic organization, the F-actin array and calcium homeostasis in Vaucheria Longicaulis var. Macounii
Creators: name: Alessa, Lilian
Publisher: name: University of British Columbia
Year: 2009

description: The single-celled alga, Vaucheria longicaulis var.macounii Blum was used as a model organism to determine the effects of aluminum on cytoplasmic organization, the Factin array and calcium homeostasis. The translocation of chloroplasts and mitochondria is a microfilament-dependent process whereas that of nuclei translocation, is microtubuledependent. The addition of aluminum (80 μM) resulted in the inhibition of microfilamentbased organelle translocation (within 60 seconds). Aluminum also caused the disorganization of cortical, cytoplasmic strands, which were visible using differential interference contrast (DIC) microscopy. These strands were shown to represent the endoplasmic reticulum in this species. Since the endoplasmic reticulum is supported by an intact F-actin array in many types of plant cells, this suggested that A l caused changes in the F-actin array in cells of V. longicaulis. Consistent with this, fluorescein labeled (FITC) phalloidin was used to show that exposure to A l resulted in the fragmentation of the F-actin array and the formation of F-actin aggregates which appeared to self-assemble in vivo. The hypothesis that aluminum causes cytoplasmic disorganization and fragmentation of the Factin array via the perturbation of calcium homeostasis was tested. The calcium-sensitive tetracarboxylate dye, fluo-3, was used to image free cytosolic calcium in this system. Treatment with aluminum caused an increase in cytosolic calcium levels within two minutes of exposure. It was noted that the response of cytosolic calcium to aluminum treatment varied between the youngest, apical region and the older, vacuolated region of the cell. Consistent with this, aluminum toxicity was particulary acute in the cell tip. The aluminum-induced rise in cytosolic calcium correlates with aluminum-induced effects on cytoplasmic streaming and the F-actih array using calcium modulators in an aluminum-free system. The use of ionomycin resulted in changes in the F-actin array which were similar, but not exactly the same as those observed during aluminum treatment. Thapsigargin and TMB-8, used to stimulate and inhibit release of calcium from intracellular stores, respectively, were used to determine whether the source of the aluminum-induced rise in cytosolic calcium was internal. Data obtained using these latter calcium modulators were inconclusive.

description: Query-based document summarization aims to extract or generate a summary of a document which directly answers or is relevant to the search query. It is an important technique that can be beneficial to a variety of applications such as search engines, document-level machine reading comprehension, and chatbots. Currently, datasets designed for query-based summarization are short in numbers and existing datasets are also limited in both scale and quality. Moreover, to the best of our knowledge, there is no publicly available dataset for Chinese query-based document summarization. In this paper, we present QBSUM, a high-quality large-scale dataset consisting of 49,000+ data samples for the task of Chinese query-based document summarization. We also propose multiple unsupervised and supervised solutions to the task and demonstrate their high-speed inference and superior performance via both offline experiments and online A/B tests. The QBSUM dataset is released in order to facilitate future advancement of this research field.

description: The site of Fermo, located in the southern part of the Marche region (central Adriatic Italy), has been the center of a lively scientific debate. Many scholars assert that during the Early Iron Age (9th–8th centuries BC) Fermo represents an enclave of the Villanovan culture (linked to the birth of the Etruscan ethnos) set in an area otherwise characterised by the Picene culture. The same scholars believe that in more recent periods (7th–6th centuries BC) the community of Fermo was completely absorbed within the Picene culture. Renato Peroni has proposed a different interpretation, according to which the ties between Fermo and the Villanovan centers arose rather from a similar protourban development. The current work proposes a new scheme of relative chronology for the site of Fermo, the outcome of a research project which has analysed a substantial number of unpublished tombs from the Misericordia and Mossa necropolises. The characteristics of each period (Fermo I, IIA, IIB, III, IVA, IVB, V) are illustrated through a selection of representative funerary contexts, which span from the 9th to the early 5th centuries BC. The paper illustrates the cultural evolution of the site both in its relationships with Middle Tyrrhenian and Po Valley regions and with the surrounding Middle Adriatic environment; new light is thereby shed on its cultural development in the 7th–6th centuries BC.

Analysis of the internal replication sequence of minute virus of mice
Creators: name: Brunstein, John
Publisher: name: University of British Columbia
Year: 2009

description: Minute Virus of Mice (MVM) is a member of the Parvovirinae genus of the Parvoviridae family of viruses. This family of small, single-stranded DNA viruses infect a wide range of eukaryotic hosts ranging from insects to humans. Due to their small size and limited coding capacity parvoviruses may serve as a suitable tool with which to examine elements of the host cell DNA replication machinery. Previous studies on MVM have localized a region of approximately 200 nucleotides inboard of the right viral genomic termini, known as the Internal Replication Sequence (IRS), which contributes in cis to viral replication competence. A comprehensive library of linker scanning mutations across the IRS of MVM was constructed and assayed in the context of a minigenomic system for replication competence in an effort to identify short sequence elements contributing to viral replication. Three elements required for efficient replication were observed. Elements of the library were also examined for interactions with host cell nuclear factors, and such interactions were localized to four sites with evidence being obtained to suggest positive interactions between the sites. These sites were found to be directly adjacent to two of the elements required for efficient replication and overlapping the third, suggesting a possible correlation between these functions. Simultaneous deletion of two of these binding sites was observed to abrogate function of the IRS, further supporting a functional relationship between factor binding and origin activity. The sequence element found to both bind, host factors and be required for replication competence was employed as 'bait' in a yeast one-hybrid genetic screen of a murine cDNA library in an attempt to clone interacting factor(s). A clone recovered from this, while not considered likely to be directly relevant, leads to postulation of a known origin binding protein RIP60 as a prospective candidate for action at the IRS origin. Preliminary studies conducted to determine whether RIP60 binds at the viral origin were conducted but failed to provide evidence of RIP60 association with the viral genome. A model is proposed whereby a leading-strand only origin of DNA replication within the region of the IRS affords a mechanism for the viral rearrangement of its 5' termini from an extended to a hairpin form during replication. Studies employing the viral IRS and right-hand terminus as an origin driving the replication of attached unrelated vector sequences are presented in support of this model.

description: The ESA Rosetta mission has acquired unprecedented measurements of comet 67/P-Churyumov-Gerasimenko (hereafter 67P) nucleus surface, whose composition, as determined by in situ and remote sensing instruments including VIRTIS (Visible, InfraRed and Thermal Imaging Spectrometer) appears to be made by an assemblage of ices, minerals, and organic material. We performed a refined analysis of infrared observations of the nucleus of comet 67P carried out by the VIRTIS-M hyperspectral imager. We found that the overall shape of the 67P infrared spectrum is similar to that of other carbon-rich outer solar system objects suggesting a possible genetic link with them. More importantly, we are also able to confirm the complex spectral structure of the wide 2.8-3.6 micron absorption feature populated by fainter bands. Among these, we unambiguously identified the presence of aliphatic organics by their ubiquitous 3.38, 3.42 and 3.47 micron bands. This novel infrared detection of aliphatic species on a cometary surface has strong implications for the evolutionary history of the primordial solar system and give evidence that comets provide an evolutionary link between interstellar material and solar system bodies.

$γ$-ray flux from Dark Matter Annihilation in Galactic Caustics

description: In the frame of indirect dark matter searches we investigate the flux of high-energy $γ$-ray photons produced by annihilation of dark matter in caustics within our Galaxy under the hypothesis that the bulk of dark matter is composed of the lightest supersymmetric particles. Unfortunately, the detection of the caustics annihilation signal with currently available instruments is rather challenging. Indeed, with realistic assumptions concerning particle physics and cosmology, the $γ$-ray signal from caustics is below the detection threshold of both $\check {\rm C}$erenkov telescopes and satellite-borne experiments. Nevertheless, we find that this signal is more prominent than that expected if annihilation only occurs in the smoothed Galactic halo, with the possible exception of a $\sim 15^{\circ}$ circle around the Galactic center if the mass density profile of our Galaxy exhibits a sharp cusp there. We show that the angular distribution of this $γ$-ray flux changes significantly if DM annihilation preferentially occurs within virialized sub-halos populating our Galaxy rather than in caustics.

description: We investigate an iterative mean value method for the inverse (and highly ill-posed) problem of solving the heat equation backwards in time. Semi-group theory is used to rewrite the solution of the inverse problem as the solution of a fixed point equation for an affine operator, with linear part satisfying special functional analytical properties. We give a convergence proof for the method and obtain convergence rates for the residual. Convergence rates for the iterates are also obtained under the so called source conditions.

description: We report our research on disordered complex systems using cold gases and trapped ions, and address the possibility of using complex systems for quantum information processing. Two simple paradigmatic models of disordered complex systems are revisited here. The first one corresponds to a short range disordered Ising Hamiltonian (spin glasses), which can be implemented with a Bose-Fermi (Bose-Bose) mixture in a disordered optical lattice. The second model we address here is a long range disordered Hamiltonian, characteristic of neural networks (Hopfield model), which can be implemented in a chain of trapped ions with appropriately designed interactions.

description: This paper introduces the foundations of the polynomial algebra and basic structures for algebraic geometry over the extended tropical semiring. Our development, which includes the tropical version for the fundamental theorem of algebra, leads to the reduced polynomial semiring -- a structure that provides a basis for developing a tropical analogue to the classical theory of commutative algebra. The use of the new notion of tropical algebraic com-sets, built upon the complements of tropical algebraic sets, eventually yields the tropical algebraic Nullstellensatz.
