description: The variational cluster approach (VCA) is applied to the one-dimensional Hubbard model at zero temperature using clusters (chains) of up to ten sites with full diagonalization and the Lanczos method as cluster solver. Within the framework of the self-energy-functional theory (SFT), different cluster reference systems with and without bath degrees of freedom, in different topologies and with different sets of variational parameters are considered. Static and one-particle dynamical quantities are calculated for half-filling as a function of U as well as for fixed U as a function of the chemical potential to study the interaction- and filling-dependent metal-insulator (Mott) transition. The recently developed Q-matrix technique is used to compute the SFT grand potential. For benchmarking purposes we compare the VCA results with exact results available from the Bethe ansatz, with essentially exact dynamical DMRG data, with (cellular) dynamical mean-field theory and full diagonalization of isolated Hubbard chains. Several issues are discussed including convergence of the results with cluster size, the ability of cluster approaches to access the critical regime of the Mott transition, efficiency in the optimization of correlated-site vs. bath-site parameters and of multi-dimensional parameter optimization. We also study the role of bath sites for the description of excitation properties and as charge reservoirs for the description of filling dependencies. The VCA turns out to be a computationally cheap method which is competitive with established cluster approaches.

description: This article is dedicated to the study of mixed zero-sum two-player stochastic differential games in the situation when the player's cost functionals are modeled by doubly controlled reflected backward stochastic equations with two barriers whose coefficients have quadratic growth in Z. This is a generalization of the risk-sensitive payoffs. We show that the lower and the upper value function associated with this stochastic differential game with reflection are deterministic and they are also the unique viscosity solutions for two Isaacs equations with obstacles.

description: We study the vector-axialvector mixing in a hot medium and its evolution toward the chiral phase transition using different symmetry restoration scenarios based on the generalized hidden local symmetry framework. We show that the presence of the $a_1$ meson reduces the vector spectral function around $ρ$ meson mass and enhances it around $a_1$ meson mass. The coupling strength of $a_1$ to $ρ$ and $π$ vanishes at the critical temperature due to the degenerate $ρ$-$a_1$ masses. This feature holds rigorously in the chiral limit and still stays intact to good approximation for the physical pion mass.

Rheological studies on the interaction of xanthan and locust bean gum in aqueous dispersions
Creators: name: Gatchair, Sonia Denise
Publisher: name: University of British Columbia
Year: 2010

description: Aqueous dispersions of xanthan and locust bean gum, in combination, show a synergistic increase in viscosity. At sufficiently high concentrations, firm gels are formed, although neither component forms true gels when alone. The actual molecular processes resulting in this phenomenon are still incompletely understood and Theological studies can provide some clues to the mechanism of the interaction. Rheological properties of the polysaccharide blend were therefore investigated. Moisture, ash and inorganic elements and protein content as well as the intrinsic viscosity of the individual polysaccharides were determined. Dynamic viscoelastic properties of dispersions prepared from the polysaccharide blend were evaluated in four solvent treatments capable of disrupting weak intermolecular bonds. The effect of polysaccharide concentration, temperature, ionic strength, pH, ratio of mixing of the two gums and urea concentration on steady shear rheological properties were evaluated in a fractional factorial experiment. More detailed studies were carried out on the effects of temperature at two levels of concentration and ionic strength. Solvent treatments significantly affected the viscoelastic properties of xanthan-locust bean gum solutions. At 20°C and under the conditions used, dipole interactions appeared to be the primary force responsible for stabilizing the xanthan-1ocust bean gum interacting system. Hydrogen bonding and hydrophobic interactions seemed to play less important roles. Under conditions of low ionic strength and increased temperature, the interactions were lost and polysaccharide solution behavior passed from that of a viscoelastic solid to that of a viscoelastic liquid. At 60°C and at high ionic strengths, hydrophobic interactions may become important in the stabilization of the three dimensional gel network. Temperature effects on steady shear viscosity of xanthan-locust bean gum solutions were dependent on the concentration and ionic strength of the system. In general, steady flow properties were comparable to the reported behavior of xanthan solutions and so reflected the weakness of the interaction (dipole interactions) between the two polysaccharides.

description: The Iraq and Afghanistan wars tremendously increased the demand among veterans for mental health services. About two in every five veterans returning from Operation Iraqi Freedom and Operation Enduring Freedom will have mental health challenges -- resulting in 500,000 to 800,000 veterans in need. Not all of these veterans will seek treatment in the Veteran Affairs Health Care System but those who do face longer and longer wait times. Increased media coverage on tragedies largely attributed to PTSD such as the 2014 Fort Hood shooting have applied greater public and political pressure on the Department of Veterans Affairs (VA) to find strategies to mitigate these unfortunate events.  This thesis seeks to build upon this public support for veteran care and work in-conjunction with the VA to develop a new, state-of-the-art Post-Traumatic Stress Disorder facility by recommending PTSD therapy centers serve local populations, promote patient recovery through architecture solutions and be removed from the institutional environments they are found in today.

description: The ultra-relativistic heavy-ion program at RHIC has shown that at intermediate transverse momenta ($p_T \simeq 2$-6 GeV) standard (independent) parton fragmentation can neither describe the observed baryon-to-meson ratios nor the empirical scaling of the hadronic elliptic flow ($v_2$) according to the number of valence quarks. Both aspects find instead a natural explanation in a coalescence plus fragmentation approach to hadronization. After a brief review of the main results for light quarks, we focus on heavy quarks showing that a combined fragmentation and quark-coalescence framework is relevant also here. Moreover, within relativistic Langevin simulations we find evidence for the importance of heavy-light resonances in the Quark-Gluon Plasma (QGP) to explain the strong energy loss and collective flow of heavy-quark spectra as inferred from non-photonic electron observables. Such heavy-light resonances can pave the way to a unified understanding of the microscopic structure of the QGP and its subsequent hadronization by coalescence.

description: We propose a novel realization for the natural extrapolation of the continuous spontaneous localization (CSL) model, in order to account for the origin of primordial inhomogeneities during inflation. This particular model is based on three main elements: (i) the semiclassical gravity framework, (ii) a collapse-generating operator associated to a relativistic invariant scalar of the energy-momentum tensor, and (iii) an extension of the CSL parameter(s) as a function of the spacetime curvature. Furthermore, employing standard cosmological perturbation theory at linear order, and for a reasonable range within the parameter space of the model, we obtain a nearly scale invariant power spectrum consistent with recent observational CMB data. This opens a vast landscape of different options for the application of the CSL model to the cosmological context, and possibly sheds light on searches for a full covariant version of the CSL theory.

Role of homeostasis in learning sparse representations

Publisher: name: arXiv
Year: 2007
Subjects: subject: Neurons and Cognition (q-bio.NC)
subject: FOS: Biological sciences

description: Neurons in the input layer of primary visual cortex in primates develop edge-like receptive fields. One approach to understanding the emergence of this response is to state that neural activity has to efficiently represent sensory data with respect to the statistics of natural scenes. Furthermore, it is believed that such an efficient coding is achieved using a competition across neurons so as to generate a sparse representation, that is, where a relatively small number of neurons are simultaneously active. Indeed, different models of sparse coding, coupled with Hebbian learning and homeostasis, have been proposed that successfully match the observed emergent response. However, the specific role of homeostasis in learning such sparse representations is still largely unknown. By quantitatively assessing the efficiency of the neural representation during learning, we derive a cooperative homeostasis mechanism that optimally tunes the competition between neurons within the sparse coding algorithm. We apply this homeostasis while learning small patches taken from natural images and compare its efficiency with state-of-the-art algorithms. Results show that while different sparse coding algorithms give similar coding results, the homeostasis provides an optimal balance for the representation of natural images within the population of neurons. Competition in sparse coding is optimized when it is fair. By contributing to optimizing statistical competition across neurons, homeostasis is crucial in providing a more efficient solution to the emergence of independent components.

An investigation of the feasibility of gooseneck barnacle mariculture (Lepas anatifera)
Creators: name: Goldberg, Harry
Publisher: name: University of British Columbia
Year: 2010

description: Gooseneck barnacles (Pollicipes cornucopia) exceeding 4 cm in length are a favourite seafood in Spain. In 1978 the British Columbia seafood industry introduced the indigenous species Pollicipes polymerus into this potentially lucrative market. Due to the problems associated with this species its export was unsuccessful. Alternatively, to fill either the void left by Pollicipes pollymerus and/or future markets, the acquisition of seed and the subsequent suspended culture of the gooseneck barnacle, Lepas anatifera, were investigated. Lepas anatifera successfully colonized the cultch (oyster shells, wooden dowelling and rubber) that was deployed at two locations off the west coast of Vancouver Island. The success of the colonization of cultch and the information obtained from a previous survey suggested that the set occurs regularly between the middle of April and the end of May off the west coast of Vancouver Island. The suspended culture of Lepas anatifera indicated that growth may be site specific and that areas of a high phytoplankton/zooplankton ratio may be detrimental to growth and time to sexual maturation. At the densities studied, survival seems to be proportional to density. Capitulum growth and weight gain were significantly greater for Lepas anatifera protected from predation within lantern nets than for those grown exposed on lines of oyster shells and wooden doweling. The average total length (capitulum plus peduncle) exceeded 4cm within 17 to 23 weeks.

description: Reopening strategies are crucial to balance efforts of economic revitalization and bringing back a sense of normalcy while mitigating outbreaks and effectively flattening the infection curve. This paper proposes practical reopening, monitoring and testing strategies for institutions to reintroduce physical meetings based on SIR simulations run on a student friendship network collected pre-Covid-19. These serve as benchmarks to assess several testing strategies that can be applied in physical classes. Our simulations show that the best outbreak mitigation results are obtained with full knowledge of contact, but are also robust to non-compliance of students to new social interaction guidelines, simulated by partial knowledge of the interactions. These results are not only applicable to institutions but also for any organization or company wanting to navigate the Covid-19 ravaged world.

Neutrino magnetic moment signatures in the supernova neutrino signal
Creators: name: Lychkovskiy, Oleg
Publisher: name: arXiv
Year: 2008
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: It is known that if neutrino is a Dirac fermion with magnetic moment, then ν_L -> ν_R -> ν_L transition of supernova neutrinos may occur. The first stage of such transition is due to the neutrino spin flip inside the hot dense supernova core, while the second one - due to the neutrino spin precession in the galactic magnetic field on the way from the supernova to terrestrial detectors. This can result in the detection of 60-200 MeV neutrinos simultaneously with the "normal" supernova neutrino signal, which would be a smoking gun for the Dirac neutrino magnetic moment, μ. We argue that in case of a nearby supernova explosion (~10 kpc away from the Earth) one may observe such high-energy events in Super-Kamiokande if μ\gtrsim 10^{-13} μ_B, and in a Mt-scale detector if μ\gtrsim 0.5*10^{-13} μ_B. Such an observation by itself, however, may be not sufficient to determine the value of the magnetic moment, because of the ignorance of the interstellar magnetic field. We point out that if in addition a deficit of the neutronization burst neutrinos is established, it would be possible to extract the value of the magnetic moment from observations. We also briefly discuss a possible Majorana magnetic moment signature due to ν_e -> \barν_{μ,τ} flip inside the supernova core.

description: An X-ray photoelectric polarimeter based on the Gas Pixel Detector has been proposed to be included in many upcoming space missions to fill the gap of about 30 years from the first (and to date only) positive measurement of polarized X-ray emission from an astrophysical source. The estimated sensitivity of the current prototype peaks at an energy of about 3 keV, but the lack of readily available polarized sources in this energy range has prevented the measurement of detector polarimetric performances. In this paper we present the measurement of the Gas Pixel Detector polarimetric sensitivity at energies of a few keV and the new, light, compact and transportable polarized source that was devised and built to this aim. Polarized photons are produced, from unpolarized radiation generated with an X-ray tube, by means of Bragg diffraction at nearly 45 degrees. The employment of mosaic graphite and flat aluminum crystals allow the production of nearly completely polarized photons at 2.6, 3.7 and 5.2 keV from the diffraction of unpolarized continuum or line emission. The measured modulation factor of the Gas Pixel Detector at these energies is in good agreement with the estimates derived from a Monte Carlo software, which was up to now employed for driving the development of the instrument and for estimating its low energy sensitivity. In this paper we present the excellent polarimetric performance of the Gas Pixel Detector at energies where the peak sensitivity is expected. These measurements not only support our previous claims of high sensitivity but confirm the feasibility of astrophysical X-ray photoelectric polarimetry.

Quantitative classification of soil nutrient regimes of some mesothermal Douglas-fir ecosystems
Creators: name: Kabzems, Richard Darwin
Publisher: name: University of British Columbia
Year: 2010

description: Previous attempts to classify nutrient regimes of forest soil have been qualitative evaluations utilizing vegetation and/or physiographic site characteristics, morphological soil properties, and parent material. The major objective of this study was to describe and classify the soil nutrient regimes (SNR) of some Pseudotsuga menziesii ecosystems on southern Vancouver Island, British Columbia. The order of increasing variability for forest floor properties was pH(H₂0) <TC <TN <TS <TP <exMg <exCa <exK <exMn <minN. The order of increasing variability for mineral soil properties was pH(H₂0)=pH(CaC1₂) <TN <TC <exP = exMg <S0₄ <minN = exK <exCa <exMn. Consistent trends in soil property variability along gradients of soil moisture or nutrient availability or between parent material lithologies were not apparent. Multivariate analysis of understory vegetation and indicator plant analysis suggested a major trend in variation corresponding to a complex environmental gradient related to increased availability of soil moisture and nutrients. The arrangement of study plots along the gradient showed groupings which corresponded to both the calculated soil water deficit and inferred soil nutrient regime. One multivariate axis accounted for most of the variation of soil properties between study plots. The mineral soil and forest floor plus mineral soil quantities of minN, TN, exCa and exMg significantly increased along the nutrient gradient. Ordinations of mineral soil and forest floor plus mineral soil properties arranged most plots according to the moisture-nutrient gradient. Discriminant analysis of the soil properties selected linear combinations of properties which separated sites, parent material lithologies, soil moisture regime classes and SNR classes. Cluster analysis confirmed that minN and exMg of the forest floor plus mineral soil best separated SNR classes. Multivariate summaries of variation in understory vegetation and foliar nutrients were highly correlated to the soil properties which best separated SNR classes. The increasing quantities of these nutrients corresponded to increases in site index for the study sites. It was concluded that significant differences in N, Ca, and Mg availability existed between SNR classes for the study sites. These differences in nutrient availability corresponded to changes in understory vegetation, foliar nutrient status and site index for the study sites. Using forest floor plus mineral soil quantities of minN and exMg, a multivariate classification of the four SNR classes recognized in this study was proposed.

description: We study Schrödinger operators on an infinite quantum graph of a chain form which consists of identical rings connected at the touching points by $δ$-couplings with a parameter $α\in\R$. If the graph is "straight", i.e. periodic with respect to ring shifts, its Hamiltonian has a band spectrum with all the gaps open whenever $α\ne 0$. We consider a "bending" deformation of the chain consisting of changing one position at a single ring and show that it gives rise to eigenvalues in the open spectral gaps. We analyze dependence of these eigenvalues on the coupling $α$ and the "bending angle" as well as resonances of the system coming from the bending. We also discuss the behaviour of the eigenvalues and resonances at the edges of the spectral bands.

Leptogenesis with exclusively low-energy CP Violation in the Context of Minimal Lepton Flavour Violation

description: We analyze lepton flavour violation (LFV) and the generation of the observed baryon-antibaryon asymmetry of the Universe (BAU) within a generalized minimal lepton flavour violation framework with three quasi-degenerate heavy Majorana neutrinos. The BAU which is obtained through radiative resonant leptogenesis can successfully be generated widely independent of the Majorana scale in this scenario and flavour effects are found to be relevant. Then we discuss the specific case in which CP violation is exclusively present at low-energies (a real R matrix) in the flavour sensitive temperature regime. Successful leptogenesis in this case leads to strong constraints on low-energy neutrino parameters.

description: Brain tumor is the most common and deadliest disease that can be found in all age groups. Generally, MRI modality is adopted for identifying and diagnosing tumors by the radiologists. The correct identification of tumor regions and its type can aid to diagnose tumors with the followup treatment plans. However, for any radiologist analysing such scans is a complex and time-consuming task. Motivated by the deep learning based computer-aided-diagnosis systems, this paper proposes multi-task attention guided encoder-decoder network (MAG-Net) to classify and segment the brain tumor regions using MRI images. The MAG-Net is trained and evaluated on the Figshare dataset that includes coronal, axial, and sagittal views with 3 types of tumors meningioma, glioma, and pituitary tumor. With exhaustive experimental trials the model achieved promising results as compared to existing state-of-the-art models, while having least number of training parameters among other state-of-the-art models.

description: Current cosmological constraints from Cosmic Microwave Background (CMB) anisotropies are typically derived assuming a standard recombination scheme, however additional resonance and ionizing radiation sources can delay recombination, altering the cosmic ionization history and the cosmological inferences drawn from CMB data. We show that for recent observations of CMB anisotropy, from the Wilkinson Microwave Anisotropy Probe satellite mission 5-year survey (WMAP5) and from the ACBAR experiment, additional resonance radiation is nearly degenerate with variations in the spectral index, n_s, and has a marked effect on uncertainties in constraints on the Hubble constant, age of the universe, curvature and the upper bound on the neutrino mass. When a modified recombination scheme is considered, the redshift of recombination is constrained to z_*=1078\pm11, with uncertainties in the measurement weaker by one order of magnitude than those obtained under the assumption of standard recombination while constraints on the shift parameter are shifted by 1-sigma to R=1.734\pm0.028. Although delayed recombination limits the precision of parameter estimation from the WMAP satellite, we demonstrate that this should not be the case for future, smaller angular scales measurements, such as those by the Planck satellite mission.

Disynaphia spathulata (Hook. & Arn.) R.M.King & H. Rob.
(syn. Eupatorium spathulatum,
common name: “macelinha”) (King and Robinson, 1987; Matzenbacher, 1979),
a sub-shrub up to 1.5 m tall, were obtained from the municipality of Canela, RS. The VO yields for the two samplings were similar despite their different vegetative stages (Table 1 and Table S1). In regard the chemical composition of the VOs of this species, the inflorescences and leaves of the first sample (Canela/05, April) showed very similar chemical compositions with a predominance of hydrocarbon monoterpenes (56.8–58.9%), especially α- pinene (7.0–11.6%), β- pinene (14.9–24.1%), limonene (12.2–13.1%), and (E)-β- ocimene (13.3–2.3%). In the sesquiterpene fraction, three main compounds were identified in the flowering period: The hydrocarbon sesquiterpenes β- caryophyllene, germacrene D, and bicyclogermacrene. However, the second sampling in the vegetative stage (Viamao/05, October) presented a very different quantitative pattern, in which oxygenated sesquiterpenes (64.1%), spathulenol (22.6%), caryophyllene oxide (7.0%), and α- cadinol (12.0%) were observed.

description: $χ^2$ vetoes are commonly used in searching for gravitational waves, in particular for broad-band signals, but they can also be applied to narrow-band continuous wave signals, such as those expected from rapidly rotating neutron stars. In this paper we present a $χ^2$ veto adapted to the Hough transform searches for continuous gravitational wave signals; we characterize the $χ^2$-significance plane for different frequency bands; and discuss the expected performance of this veto in LIGO analysis.
