description: The processes of electron-positron annihilation into $π^0γ$ and into $π'(1300)γ$ are considered within the NJL model. Intermediate vector mesons $ρ^0$, $ω$, $ρ'(1450)$, and $ω'(1420)$ are taken into account. The latter two mesons are treated as the first radial excited states. They are incorporated into the NJL model by means of a polynomial form factor. Numerical predictions for the cross sections of these processes are received for the center-of-mass energies below 2 GeV. Our results for the $π^0γ$ production are in agreement with experimental data received in the energy region 600 -- 1020 MeV.

description: The number of independent sets is equivalent to the partition function of the hard-core lattice gas model with nearest-neighbor exclusion and unit activity. We study the number of independent sets $m_{d,b}(n)$ on the generalized Sierpinski gasket $SG_{d,b}(n)$ at stage $n$ with dimension $d$ equal to two, three and four for $b=2$, and layer $b$ equal to three for $d=2$. The upper and lower bounds for the asymptotic growth constant, defined as $z_{SG_{d,b}}=\lim_{v \to \infty} \ln m_{d,b}(n)/v$ where $v$ is the number of vertices, on these Sierpinski gaskets are derived in terms of the results at a certain stage. The numerical values of these $z_{SG_{d,b}}$ are evaluated with more than a hundred significant figures accurate. We also conjecture the upper and lower bounds for the asymptotic growth constant $z_{SG_{d,2}}$ with general $d$.

The systems neurobiology of autism spectrum disorders (ASD) : a histological and functional approach
Creators: name: Cairns, James Maxwell
Publisher: name: University of British Columbia
Year: 2015

description: Objective: To explore the relationship between cerebellar pathology and changes in neuronal activity in mouse models of autism-like phenotypes. Methods: We used the rotarod test as a measure of sensorimotor function in our mice and as a means to trigger neuronal activation. Following behavioural testing we obtained brain tissue from our ASD-like mouse models and used histology and microscopy to examine the expression of cFos (a reporter of neuronal activity) and several other structural and functional markers to evaluate cerebellar pathology. Finally, we looked at differences in the morphology, distribution and number of cerebellar glia in our ASD-like mouse models to determine if reactive gliosis contributes to further cerebellar pathology in adult mice. Results: Compared to wildtype littermates, Lc/+ mutant mice performed significantly worse on the rotarod assay of sensorimotor function (p<0.0001). In addition, Lc/+ mutants have significantly increased neuronal activity in the cerebellum and cortex at rest and following cerebellar rotarod activation as compared to wildtype littermates (p<0.05 for each group). Lurcher chimeras with the severest cerebellar pathology have increased neuronal activity in the GCL and CN neurons, but decreased neural activity in inhibitory PCs and they have increased numbers of activated microglia and Bergmann glia in the cerebellar cortex. Fmr1 KO mice have a slight decrease in PC numbers as compared to Fmr1 wildtypes (p=0.0862 n.s) with alterations in neuronal activity at rest in the cerebellar GCL and cortex. Conclusion: Variable cerebellar pathology seen in human cases of autism and in ASD-like mouse models in the form of neuron loss, microgliosis and astrogliosis leads to changes in excitatory and inhibitory activity in surviving cerebellar neurons. Structural and functional changes documented in Lc/+ mutants, chimeras and Fmr1 KO mice revealed neuroanatomical abnormalities and functional changes in cerebellar neural circuits which may lead to a better understanding of the neurobiological changes occurring in the cerebellum that contribute to ASD-like phenotypes. By identifying cerebellar neurons and glia that are involved in pathological processes in mouse models of neurodevelopmental disorders, it is hoped that these results will provide fresh insights into neurobiological changes underlying ASD-like phenotypes.

description: This thesis is primarily concerned in studying the relationship between different exponents of Diophantine approximation, which are quantities arising naturally in the study of rational approximation to a fixed n-tuple of real irrational numbers. As Khinchin observed, these exponents are not independent of each other, spurring interest in the study of the spectrum of a given family of exponents, which is the set of all possible values that can be taken by said family of exponents. Introduced in 2009-2013 by Schmidt and Summerer and completed by Roy in 2015, the parametric geometry of numbers provides strong tools with regards to the study of exponents of Diophantine approximation and their associated spectra by the introduction of combinatorial objects called n-systems. Roy proved the very surprising result that the study of spectra of exponents is equivalent to the study of certain quantities attached to n-systems. Thus, the study of rational approximation can be replaced by the study of n-systems when attempting to determine such spectra. Recently, Roy proved two new results for the case n=3, the first being that spectra are semi-algebraic sets, and the second being that spectra are stable under the minimum with respect to the product ordering. In this thesis, it is shown that both of these results do not hold in general for n>3, and examples are given. This thesis also provides non-trivial examples for n=4 where the spectra is stable under the minimum. An alternate and much simpler proof of a recent result of Marnat-Moshchevitin proving an important conjecture of Schmidt-Summerer is also given, relying only on the parametric geometry of numbers instead. Further, a conjecture which generalizes this result is also established, and some partial results are given towards its validity. Among these results, the simplest, but non-trivial, new case is also proven to be true. In a different vein, this thesis considers certain generalizations theta(q) of the classical theta q-series. We show under conditions on the coefficients of the series that theta(q) is neither rational nor quadratic irrational for each integer q>1.

description: The evolution of the ground-state nuclear shapes in neutron-rich Sr, Zr, and Mo isotopes, including both even-even and odd-A nuclei, is studied within a self-consistent mean-field approximation based on the D1S Gogny interaction. Neutron separation energies and charge radii are calculated and compared with available data. A correlation between a shape transition and a discontinuity in those observables is found microscopically. While in Sr and Zr isotopes the steep behavior observed in the isotopic dependence of the charge radii is a consequence of a sharp prolate-oblate transition, the smooth behavior found in Mo isotopes has its origin in an emergent region of triaxiality.

description: Walkability indices are currently used for a wide range of research and commercial applications. Few studies have examined the relationship between walkability indices and measured pedestrian volume or walking rates, nor explored moderators of pedestrian volume such as weather. With 14 years of traffic study data from the City of Ottawa, a spatial auto-regressive (SAR) multi-level model (MLM) was used to understand the proportion of variance in walking explained by the commercial Walk Score® index and selected weather variables. Modeling revealed that a significant proportion of pedestrian volume at a given location in Ottawa, including its spatial lag, was explained by the corresponding Walk Score® value and its spatial lag (51.45%). Furthermore, weather expressed as a combination of ‘felt’ temperature, presence or absence of precipitation, and percent cloud cover, accounted for 2.79% of the variance in walking. These findings indicate that walkability indices may provide value as cost-effective engineering and urban planning tools.

two-stream convolutional network

description: With the emergence of Convolutional Neural Network (CNN) models, precision of image classification tasks has been improved significantly over these years. Regional CNN (RCNN) model is proposed to solve object detection tasks with a combination of Region Proposal Network and CNN. This model improves the detection accuracy but suffer from slow inference speed because of its multi-stage structure. The Single Stage Detection (SSD) network is later proposed to further improve the object detection benchmark in terms of accuracy and speed. However, SSD model still suffers from high miss rate on small targets since datasets are usually dominated by medium and large sized objects, which don’t share the same features with small ones. On the other hand, geometric analysis on dataset images can provide additional information before model training. In this thesis, we propose several SSD-based models with adjusted parameters on feature extraction layers by using geometric analysis on KITTI and Caltech Pedestrian datasets. This analysis extends SSD’s capability on small objects detection. To further improve detection accuracy, we propose a two-stream network, which uses one stream to detect medium to large objects, and another stream specifically for small objects. This two-stream model achieves competitive performance comparing to other algorithms on KITTI and Caltech Pedestrian benchmark. Those results are shown and analysed in this thesis as well.

description: We present CCD photometric distance estimates of 100 SCR (SuperCOSMOS RECONS) systems with $μ$ $\geq$ 0$\farcs$18/yr, 28 of which are new discoveries previously unpublished in this series of papers. These distances are estimated using a combination of new $VRI$ photometry acquired at CTIO and $JHK$ magnitudes extracted from 2MASS. The estimates are improvements over those determined using photographic plate $BRI$ magnitudes from SuperCOSMOS plus $JHK$, as presented in the original discovery papers. In total, 77 of the 100 systems investigated are predicted to be within 25 pc. If all 77 systems are confirmed to have $π$$_{trig}$ $\ge$ 40 milliarcseconds, this sample would represent a 23% increase in M dwarf systems nearer than 25 pc in the southern sky.

When $a$ is much larger than the Lorentz factor of a radiating electron $γ$, synchrotron radiation is realized, while $a\ll 1$ corresponds to the so-called jitter radiation regime. Because for $1

description: In this paper, we look at the improvement of our knowledge on a family of tilings of the hyperbolic plane which is brought in by the use of Sergeyev's numeral system based on grossone. It appears that the information we can get by using this new numeral system depends on the way we look at the tilings. The ways are significantly different but they confirm some results which were obtained in the traditional but constructive frame and allow us to obtain an additional precision with respect to this information.

We analyze this effect by a combination of density functional, many-body perturbation and numerical renormalization group theory, taking into account both the non-locality and the dynamics of electronic correlation. Our findings, in particular the evolution from a broad quasiparticle resonance below to a narrow Kondo resonance at the Fermi energy, correspond to the experimental observations.

The most well-documented innovations are those in the fields of medical science (traumatology), meteorology, and ethnology, as well as the research conducted at the Vienna University of Technology, which was essential for the war effort. For Austrian universities in general, these were years of deprivation and large losses in teachers and students. Due to the devastation caused by the war, the death and brain drain of scientists, and the destruction of the financial resources, the First Austrian Republic was unable to build on the high level of scientific research reached before the outbreak of First World War.

Throughout the interwar period, some of Yugoslavia’s war veterans attempted to craft the fledgling state in their own image while others remained hostile to it throughout its existence. Veterans’ variegated experiences engendered several interpretations of Yugoslavia and Yugoslavism, ultimately leading to an inability to forge Yugoslavs. Without a unified vision for the state and its peoples, interwar Yugoslavia was weak, vulnerable and, especially after the assassination of King Aleksandar in 1934, leaderless.

description: The quantum localization in the quantum Hall regime is revisited using Graphene monolayers with accurate measurements of the longitudinal resistivity as a function of temperature and current. We experimentally show for the first time a cross-over from Efros-Shklovskii Variable Range Hopping (VRH) conduction regime with Coulomb interactions to a Mott VRH regime without interaction. This occurs at Hall plateau transitions for localization lengths larger than the interaction screening length set by the nearby gate. Measurements of the scaling exponents of the conductance peak widths with both temperature and current give the first validation of the Polyakov-Shklovskii scenario that VRH alone is sufficient to describe conductance in the Quantum Hall regime and that the usual assumption of a metallic conduction regime on conductance peaks is unnecessary.

description: Since photospheric bright points (BPs) were first observed, there has been a question as to how are they structured. Are they just single flux tubes or a bundle of the flux-tubes? Surface photometry of the quiet Sun (QS) has achieved resolution close to 0.1" with the New Solar Telescope at Big Bear Solar Observatory. This resolution allowed us to detect a richer spectrum of BPs in the QS. The smallest BPs we observed with TiO 705.68 nm were 0.13", and we were able to resolve individual components in some of the BPs clusters and ribbons observed in the QS, showing that they are composed of the individual BPs. Average size of observed BPs was 0.22".

Probing the electrostatics and hydrodynamics in gas-solid fluidized beds
Creators: name: He, Chuan
Publisher: name: University of British Columbia
Year: 2015

description: Novel electrostatic dual-tip probes, combined with suitable signal analysis methods, were developed for in-situ measurement and monitoring of particle charge density levels and bubble properties inside gas-fluidized beds. The probes were calibrated in several particulate flow devices : ejector-funnel, motor-pulley, vertical tube and vibration tray setups, as well as a two-dimensional fluidized bed. The effects of particle charge density, solid flux, particle velocity and angle of impact on the transferred current received by the probe from charged particles were quantified. For dual-tip (two-material) probes, substantial differences were observed in the signals from the two tips made of different materials, arising mainly from charge transfer and depending on the hydrodynamics and charge density inside the bed. The probes were deployed with glass beads and polyethylene particles for both single bubble injection and freely bubbling experiments in two- and three-dimensional fluidization columns of different scales. Statistical and Fast Fourier Transform analysis showed that current signals were strongly affected by the local hydrodynamics in the fluidized bed. The amplitudes of current signal peaks, peak frequencies, as well as mean and standard deviations of the current increased with increasing superficial gas velocity. Local particle charge density and bubble behaviour were estimated by a signal processing procedure with decoupling methods. The probes were tested in steady state experiments, as well as in dynamic experiments by abruptly changing the superficial gas velocity or adding antistatic agent. Both particle charge density and bubble rise velocity obtained from the probes were of the same order of magnitude and followed similar trends as those directly measured by a Faraday cup and video images, respectively. The electrostatic probe signal was found to not always be consistent with the charge polarity and charge density on the particles. The probe signals and particles charge densities may have different polarity and relative magnitudes for different operating conditions and particle properties : density, mean size and size range, dielectric constant, sphericity, roughness and hydrophobicity. Particles with narrow size distribution and larger mean size generated higher charge densities. The novel probe has potential for in-situ monitoring electrostatic charges and hydrodynamic behaviour in gas-solid fluidized beds.
Notes on the post-Newtonian limit of massive Brans-Dicke theory

description: We consider the Post-Newtonian limit of massive Brans-Dicke theory and we make some notes about the Post-Newtonian limit of the case $ω=0$. This case is dynamically equivalent to the metric $f(R)$ theory. It is known that this theory can be compatible with the solar system tests if Chameleon mechanism occurs. Also, it is known that this mechanism is because of the non-linearity in the field equations produced by the largeness of the local curvature relative to the background curvature. Thus, the linearization of the field equations breaks down. On the other hand we know that Chameleon mechanism exists when a coupling between the matter and the scalar field exists. In the Jordan frame of Brans-Dicke theory, we have not such a coupling. But in the Einstein frame this theory behaves like a Chameleon scalar field. By confining ourselves to the case $ω=0$, we show that "Chameleon-like" behavior can exist also in the Jordan frame but it has an important difference compared with the Chameleon mechanism. Also we show that the conditions which lead to the existence of "Chameleon-like" mechanism are consistent with the conditions in the Post-Newtonian limit which correspond to a heavy scalar filed at the cosmological scale and a small effective cosmological constant. Thus, one can linearize field equations to the Post-Newtonian order and this linearization has not any contradiction with the existence of "Chameleon-like" behavior.

description: A minimal representation of a simple non-compact Lie group is obtained by ``quantizing'' the minimal nilpotent coadjoint orbit of its Lie algebra. It provides context for Roger Howe's notion of a reductive dual pair encountered recently in the description of global gauge symmetry of a (4-dimensional) conformal observable algebra. We give a pedagogical introduction to these notions and point out that physicists have been using both minimal representations and dual pairs without naming them and hence stand a chance to understand their theory and to profit from it.

description: Between 1914 and 1918, between 150,000 and 200,000 Africans traveled to Europe to labor in support of the war effort. Most came from French colonies, but many also came from British colonies in Africa. They worked in diverse settings and on a variety of tasks, from factories to ports, from farm labor to road repair, and many more. Aside from long hours and backbreaking work, these men endured segregation, racism, and violence, but they also learned new skills, encountered new ideas about organized labor, and even sometimes interacted with Europeans in an environment that was less racist than what they had lived under in the colonies. African laborers were shipped home from Europe as soon as possible after the armistice, yet their time in Europe was important not only for the war effort, but for shaping their lives in Africa after 1918.

description: We show that silicon nitride can provide uniform coverage of graphene in field-effect transistors while preserving the channel mobility. This insulator allowed us to study the maximum channel resistance at the Dirac (neutrality) point as a function of the strength of a perpendicular electric field in top-gated devices with different numbers of graphene layers. Using a simple model to account for surface potential variations (electron-hole puddles) near the Dirac point we estimate the field-induced band-gap or band-overlap in the different layers.
Visceral exposure : Melanie Gilligan, Hito Steyerl, and the biopolitics of visibility
Creators: name: Steinmann, Catherine A.
Publisher: name: University of British Columbia
Year: 2016

description: This study considers a small group of recent video works by artists Melanie Gilligan and Hito Steyerl through the Foucauldian lens of biopolitics. I argue that these works implicitly reveal how biopower viscerally exposes and abstracts the neoliberal subject, constructing it in precarious tension as ostensibly coherent yet infinitely fissionable. Introducing the study by discussing the concept of biopower in Michel Foucault’s work, I also draw on work by Gilles Deleuze, Boris Groys, Brian Massumi, and others to suggest how biopower shapes the subject through ever-expanding forms of surveillance and documentation. Biopower does not merely take advantage of the subject’s legibility, however; instead, I argue, it produces subjectivity through visual and data-driven forms of description that tend to both function and be masked as representation. In the second chapter, I contend that Steyerl’s Strike (2010) and Strike II (2012) and Gilligan’s Popular Unrest (2010) intimate how biopolitical subjecthood is fashioned through photographic, behavioral, physiological, and other technoscientific forms of tracking and modelling. These works propose “strikes” against biopower’s relentlessly visualizing drive. I argue in chapter three that Gilligan’s Popular Unrest and Steyerl’s Lovely Andrea (2007) and Red Alert (2007) make explicit the relationship between contemporary forces of intensity and abstraction (formal, economic, social), revealing them as complementary dimensions of biopower that produce a fractured, divided subject amenable to “orderly” visualization. These works propose the redemptive potential of redeployments of affect. In the fourth chapter, I argue that Gilligan’s Self-Capital and Steyerl’s In Free Fall (both 2009) demonstrate the relationship of global economic crisis to crises of biopolitical subjectivity. Gilligan’s work suggests the character of the archetypical neoliberal subject Foucault describes as “entrepreneur of himself,” tracing its modes of self-production and projecting its imminent collapse. Steyerl’s turns away from the subject, exploring the vitality and agency of the object and questioning object-subject distinctions. In different ways, Gilligan and Steyerl offer proposals for shedding a biopolitical subjectivity that is increasingly untenable. Illuminating the role of visceral exposure in the biopolitics of subjectivation while reconfiguring this very process, their work extends and exceeds other forms of political engagement with the problem of biopolitics.

description: Künstliche Intelligenz (KI) hat das Potential, die Wertschöpfung in allen Branchen nachhaltig zu verändern. Um dieses Potential am Standort Deutschland zu nutzen, ist es essentiell zu verstehen, welche Arten von KI in Deutschland produziert werden und wie diese zur Wertschöpfung beitragen. Der KI-Produktionsprozess von KI ist dabei keine Zauberei, sondern ein unternehmerischer Prozess der von Akteuren, wie beispielsweise Unternehmensgründern, mit einer bestimmten Motivation gestaltet und durchgeführt wird. Jessica Schmeiss und Nicolas Friederici beleuchten in dieser Einführung zum Thema KI das Potential für die deutsche Wirtschaft. Der Beitrag ist der erste Teil der „Demystifying AI in entrepreneurship –What's behind German AI production?“ Studie, die in 2019 am HIIG veröffentlicht wird.

description: We present an analysis of the rms variability spectra of a sample of 18 observations of 14 Seyfert galaxies observed by XMM-Newton, which exhibit sufficient variability and signal-to-noise ratio to examine the variations in the iron K-band. The narrow core of the K alpha line at 6.4 keV, seen universally in Seyferts, shows minimal evidence for variability and is always less variable than the continuum, supporting an origin in distant material such as the torus. At least half the observations do show evidence for variations in the wider iron K-band, however, and in at least 5 cases the excess line variations appear to be broad. The simplest prediction -- that the broad emission line is as variable as the continuum -- is generally not confirmed as only two observations show this type of behaviour. In four cases, the red wing of the line is more variable than the power-law continuum and extends down to energies of ~ 5 keV. Three observations show strong variability blueward of the line core that could also be from the disk, but alternatively might be due to emission or absorption by other hot or photoionised gas close to the nucleus. In cases where this excess blue variability is present, it is not always seen in the time-averaged spectrum. Six observations possess a broad iron line in the time-averaged spectra but with an invariant red wing, and three of these six show no variability across the entire iron line region. This suggests a decoupling of the continuum and reflection component, perhaps due to light bending or other anisotropic effects as has been suggested for MCG-6-30-15 and other narrow-line Seyfert 1s. A key result is that the rms spectra of objects such as NGC 3516 do not agree with complex absorption effects mimicking the broad red wing.

description: We have measured quantum transport through an individual Fe$_4$ single-molecule magnet embedded in a three-terminal device geometry. The characteristic zero-field splittings of adjacent charge states and their magnetic field evolution are observed in inelastic tunneling spectroscopy. We demonstrate that the molecule retains its magnetic properties, and moreover, that the magnetic anisotropy is significantly enhanced by reversible electron addition / subtraction controlled with the gate voltage. Single-molecule magnetism can thus be electrically controlled.
Spin-Currents and Spin-Pumping Forces for Spintronics

description: A general definition of the Spintronics concept of spin-pumping is proposed as generalized forces conjugated to the spin degrees of freedom in the framework of the theory of mesoscopic non-equilibrium thermodynamics. It is shown that at least three different kinds of spin-pumping forces and associated spin-currents can be defined in the most simple spintronics system (the Ferromagnetic/Non-Ferromagnetic metal interface). Furthermore, the generalized force associated to the ferromagnetic collective variable is also introduced in an equal footing, in order to describe the coexistence of the spin of the conduction electrons (paramagnetic spins attached to $s$-band electrons) and the ferromagnetic-order parameter. The dynamical coupling between these two kinds of magnetic degrees of freedom is presented, and interpreted in terms of spin-transfer effects.

description: Hydrophobic inorganic films were obtained by direct deposition of copper or silicon onto natural lotus leaves by ion beam sputtering deposition technique. Scanning electron microscopy observations showed a lotus-leaf-like surface structure of the deposited inorganic films. Hydrophobic nature of the inorganic films on lotus leaves had been improved compared to the inorganic films deposited on flat silicon substrates. Water contact angles measured on the lotus-leaf-like copper and silicon films were 136.3 \pm 8° and 117.8 \pm 4.4°, respectively. The hydrophobic lotus-leaf-like inorganic films had been repeated used as nanoimprint stamps. Negative structures of lotus-leaf-like inorganic films were obtained on the polystyrene resist layers.

description: The canting angles and fluctuation of the magnetic ion spins of spinel oxide MnCr${}_2$O${}_4$ were studied by nuclear magnetic resonance (NMR) at low temperatures, which has a collinear ferrimagnetic order below $T_C$ and a ferrimagnetic spiral order below $T_s < T_C$. Contrary to previous reports, only one spin canting angle of Cr ions was observed. The spin canting angles of Mn and Cr ions in the ferrimagnetic spiral obtained at a liquid-He temperature were $43\,^{\circ}$ and $110\,^{\circ}$, respectively. The nuclear spin-spin relaxation was determined by the Suhl-Nakamura interaction at low temperatures but the relaxation rate $T_2^{-1}$ increases rapidly as the temperature approaches $T_s$. This indicates that the fluctuation of the spiral component becomes faster as the temperature increases but not fast enough to leave an averaged hyperfine field to nuclei in the time scale of nuclear spin precession in the ferrimagnetic phase, which is on the order of $10^{-8}$ s. The spiral volume fraction measured for various temperatures reveals that the collinear and the spiral ferrimagnetic phases are mixed below the transition temperature of the spiral order. The temperature hysteresis in the volume fraction implies that this transition has first-order characteristics.
