description: We present a class of dynamical solutions in a D-dimensional gravitational theory coupled to a dilaton, a form field strength, and a cosmological constant. We find that for any D due to the presence of a cosmological constant, the metric of solutions depends on a quadratic function of the brane world volume coordinates, and the transverse space cannot be Ricci flat except for the case of 1-branes. We then discuss the dynamics of 1-branes in a D-dimensional spacetime. For a positive cosmological constant, 1-brane solutions with D>4 approach the Milne universe in the far-brane region. On the other hand, for a negative cosmological constant, each 1-brane approaches the others as the time evolves from a positive value, but no brane collision occurs for D>4, since the spacetime close to the 1-branes eventually splits into the separate domains. In contrast, the D=3 case provides an example of colliding 1-branes. Finally, we discuss the dynamics of 0-branes and show that for D>2, they behave like the Milne universe after the infinite cosmic time has passed.

description: Let G be a reductive algebraic group over the complex number filed, and K = G^θ be the fixed points of an involutive automorphism θof G so that (G, K) is a symmetric pair. We take parabolic subgroups P and Q of G and K respectively and consider a product of partial flag varieties G/P and K/Q with diagonal K-action. The double flag variety G/P \times K/Q thus obtained is said to be of finite type if there are finitely many K-orbits on it. A triple flag variety G/P^1 \times G/P^2 \times G/P^3 is a special case of our double flag varieties, and there are many interesting works on the triple flag varieties. In this paper, we study double flag varieties G/P \times K/Q of finite type. We give efficient criterion under which the double flag variety is of finite type. The finiteness of orbits is strongly related to spherical actions of G or K. For example, we show a partial flag variety G/P is K-spherical if a product of partial flag varieties G/P \times G/θ(P) is G-spherical. We also give many examples of the double flag varieties of finite type, and for type AIII, we give a classification when P = B is a Borel subgroup of G.

Phosphorus recovery from a membrane enhanced biological phosphorus removal (MEBPR) process
Creators: name: Yue, Chaoyang
Publisher: name: University of British Columbia
Year: 2017

description: Phosphorus is an essential yet limited element for sustaining life of human beings. Municipal wastewater contains rich phosphorus, which is not sufficiently recovered or recycled. This dissertation developed a system that could recover phosphorus from wastewater as struvite fertilizer (MgNH₄PO₄•6H₂O). Such a system included three major components — a membrane enhanced biological phosphorus removal (MEBPR) process, a side-stream unit to extract PO₄³⁻ and NH₄⁺ from wasted solids, and a struvite crystallizer. This dissertation focused on optimizing the first two steps through pilot- and bench-scale studies, respectively. The MEBPR process was tested at increasing solids retention time (SRT) to increase total phosphorus (TP) concentration in mixed liquor (ML). The operation at SRT = 60 days proved to be technically feasible and achieved comparable phosphorus removal (95−96 %) and organic carbon removal (91−92 %) to that observed during operation at the control SRT (25 days). The 60-day SRT operation also removed 14 % more nitrogen, wasted 17 % less dry solids, more than doubled the TP concentration of aerobic zone ML, but did not increase membrane fouling rates. Cost analyses showed that the energy requirements were 0.94 and 2.1 kWh/m³ of permeate for SRT = 25 and 60 days, both within the reported range for full-scale membrane bioreactors. To solve foaming problem in the MEBPR process, foam was characterized as an alternative resource for phosphorus recovery. Methods were assessed to extract phosphorus from ML and foam. With suitable conditions, microwave-based hydrogen peroxide advanced oxidation process (MW-H₂O₂ AOP) could extract > 90 % of TP as PO₄-P from foam, and anaerobic P-release could extract up to 60 % from ML. Anaerobic digestion could extract 44−46 % of TP under digestion pHs, 64−65 % with pH ≤ 5.5, and generate sufficient NH₄⁺ that matched the quantities of PO₄³⁻ extracted. Finally, a system was proposed that included an MEBRP process operating at SRT = 60 days, and an anaerobic digester to extract both PO₄³⁻ and NH₄⁺. This system could recover about 60 % of the incoming phosphorus in the influent. To recover more phosphorus, MW-H₂O₂ AOP could be used after anaerobic digestion, whenever justified.

description: We introduce a novel technique for empirically understanding galaxy evolution. We use empirically determined stellar evolution models to predict the past evolution of the Sloan Digital Sky Survey (SDSS-II) Luminous Red Galaxy (LRG) sample without any a-priori assumption about galaxy evolution. By carefully contrasting the evolution of the predicted and observed number and luminosity densities we test the passive evolution scenario for galaxies of different luminosity, and determine minimum merger rates. We find that the LRG population is not purely coeval, with some of galaxies targeted at z<0.23 and at z>0.34 showing different dynamical growth than galaxies targeted throughout the sample. Our results show that the LRG population is dynamically growing, and that this growth must be dominated by the faint end. For the most luminous galaxies, we find lower minimum merger rates than required by previous studies that assume passive stellar evolution, suggesting that some of the dynamical evolution measured previously was actually due to galaxies with non-passive stellar evolution being incorrectly modelled. Our methodology can be used to identify and match coeval populations of galaxies across cosmic times, over one or more surveys.

Natural attenuation of biodiesel in a sandtank experiment
Creators: name: Scully, Keelin
Publisher: name: University of British Columbia
Year: 2017

description: The use of alternative fuels, including biodiesel, has increased steadily in the last two decades, increasing the risk of accidental spills. However, a comprehensive understanding of the fate of biodiesel in the subsurface is currently lacking. A large sandtank experiment was conducted over 18 months to evaluate the spatial and temporal evolution of biodiesel biodegradation with a focus on vadose zone impacts. 80 L of biodiesel was applied to the center of the sandtank. Monitoring and analysis focused on two zones: the saturated zone including the capillary fringe, and the unsaturated zone. Measured parameters included surficial CO2 and CH4 effluxes, gas concentrations and their isotopic composition in the vadose zone, moisture contents and temperature. In the saturated zone, groundwater chemistry was characterized based on dissolved cation and anion concentrations, volatile fatty acids (VFAs), pH and alkalinity. The experimental results displayed a rapid response to the biodiesel release, revealed by increases of surficial CO2 effluxes and CO2-concentrations in the vadose zone, while O2 concentrations remained close to atmospheric levels. In the saturated zone, elevated VFA concentrations were observed together with pronounced increases in cation concentrations, specifically Ca, Mg, Fe and Mn, indicating the rapid development of anaerobic conditions. The generation of acidity associated with aerobic and anaerobic degradation reactions led to a decline in pH, locally to values below 5, likely inhibiting the progress of biodegradation. The onset of CH4 generation was delayed and coincided with reaching maximum VFA concentrations in the saturated zone. CH4 effluxes at the ground surface were limited; however, stable isotope analysis indicated that CH4 oxidation in the vadose zone was weak, likely due to low-pH conditions. Increases in dissolved concentrations of Fe and Mn were attributed to the reductive dissolution of Mn- and Fe-oxides, with possible contributions from the dissolution of Fe- and Mn-bearing dolomite. Carbon balance estimates showed that the biodiesel was recalcitrant to degradation, and at 590 days less than 5% of the biodiesel had been transformed to VFAs, CO2 and CH4. The average biodiesel degradation rate derived from the carbon balance is 1.3 x 10-8 mol L-1 H2O s-1, comparable to literature values.
Discovering Higgs Bosons of the MSSM using Jet Substructure

description: We present a qualitatively new approach to discover Higgs bosons of the MSSM at the LHC using jet substructure techniques applied to boosted Higgs decays. These techniques are ideally suited to the MSSM, since the lightest Higgs boson overwhelmingly decays to $b\bar{b}$ throughout the entire parameter space, while the heavier neutral Higgs bosons, if light enough to be produced in a cascade, also predominantly decay to $b\bar{b}$. The Higgs production we consider arises from superpartner production where superpartners cascade decay into Higgs bosons. We study this mode of Higgs production for several superpartner hierarchies: $m_{\tilde{q}}, m_{\tilde g} > m_{\tilde{W},\tilde{B}} > m_h + μ$; $m_{\tilde{q}}, m_{\tilde g} > m_{\tilde{W},\tilde{B}} > m_{h,H,A} + μ$; and $m_{\tilde{q}}, m_{\tilde g} > m_{\tilde{W}} > m_h + μ$ with $m_{\tilde{B}} \simeq μ$. In these cascades, the Higgs bosons are boosted, with $p_T > 200$ GeV a large fraction of the time. Since Higgs bosons appear in cascades originating from squarks and/or gluinos, the cross section for events with at least one Higgs boson can be the same order as squark/gluino production. Given 10 fb$^{-1}$ of 14 TeV LHC data, with $m_{\tilde{q}} \lsim 1$ TeV, and one of the above superpartner mass hierarchies, our estimate of $S/\sqrt{B}$ of the Higgs signal is sufficiently high that the $b\bar{b}$ mode can become the discovery mode of the lightest Higgs boson of the MSSM.

The controversial $Δ(1750)P_{31}$ is not seen. The evidence is derived from a study of data on pion- and photo-induced hyperon production, but other data are included as well. Most of the resonances reported here were found in the Karlsruhe-Helsinki (KH84) and the Carnegie-Mellon (CM) analyses but were challenged recently by the Data Analysis Center at GWU. Our analysis is constrained by the energy independent $πN$ scattering amplitudes from either KH84 or GWU. The two $πN$ amplitudes from KH84 or GWU, respectively, lead to slightly different $πN$ branching ratios of contributing resonances but the debated resonances are required in both series of fits.

Exascale Ready Work-Optimal Matrix Inversion

description: In dieser Diplomarbeit entwickle ich einen neuen Algorithmus OPT zur Inversion von Matrizen. Ich beweise Eigenschaften zur parallelen Laufzeit und zum Arbeitsaufwand von OPT. OPT ist kombiniert aus Strassens Algorithmus zur Inversion von Matrizen und aus Newton Approximation und basiert auf einer Subroutine zur Matrixmultiplikation.
OPT ist ein arbeitsoptimaler Algorithmus, d.h. er benötigt höchstens einen konstanten Faktor mehr Arbeit als jeder andere (arbeitsoptimale) Algorithmus. Außerdem benötigt OPT nur plylogarithmische Zeit auf höchstens O(n3) Prozessoren, wobei die Prozessorzahl von der Multiplikationsroutine bestimmt wird. Damit vereint er diese beiden Vorteile von Strassens Algorithmus und Newton Approximation.
Ich beweise eine neue Abschätzung zur numerischen Stabilität von Strassens Algorithmus kombiniert mit Newton Approximation.
Im Zuge der Diplomarbeit habe ich OPT, Strassens Inversionsalgorithmus und Newton Approximation zusammen mit einer Matrixcontainerklasse in einem flexiblen Testprogramm implementiert. Ich beschreibe das Design der Implementierung und die Verwendung und Schwierigkeiten von BLAS für die Matrixmultiplikationsroutine.
Im experimentellen Teil vergleiche ich die Laufzeit und die numerische Stabilität von OPT mit der Routine aus der Intel Math Kernel Library (MKL). Die konstanten Faktoren des Arbeitsaufwands von OPT erweisen sich als nicht mehr als doppelt so hoch wie die der MKL-Routine. Wie vorhergesagt skaliert OPT sehr gut. Selbst auf einem Computer mit nur acht Kernen ist er bereits deutlich schneller als die MKL-Routine.
Bezüglich der numerischen Stabilität werden OPT und Strassens Algorithmus dessen schlechtem Ruf nicht gerecht. Stattdessen erzeugen sie Ergebnisse vergleichbar mit denen der MKL-Routine. Ich entdecke eine unerwartete Instabilität von Newton Approximation wodurch sie schlechtere Ergebnisse erzeugt als alle anderen Algorithmen in der Implementierung. Zu dieser Instabilität präsentiere ich einige weitere Experimente.

description: We present a mid-IR investigation of the scaling relations between supermassive black hole masses (MBH) and the structural parameters of the host spheroids in local galaxies. The work is based on two-dimensional bulge-disk decompositions of Spitzer/IRAC 3.6 um images of 57 galaxies with MBH estimates. Our estimates of effective radii (Re) and surface brightnesses, combined with velocity dispersions (sigma) from the literature, define a FP relation consistent with previous determinations but doubling the observed range in Re. None of our galaxies is an outlier of the FP, demonstrating the accuracy of our bulge-disk decomposition which also allows us to independently identify pseudobulges in our sample. We calibrate M/L at 3.6 um by using the tight Mdyn-Lbul relation (~0.1 dex of rms) and find that no color corrections are required to estimate the stellar mass. The 3.6 um luminosity is thus the best tracer of Mstar yet studied. We then explore the connection between MBH and bulge structural parameters (luminosity, mass, effective radius). We find tight correlations of MBH with both 3.6 um bulge luminosity and dynamical mass (MBH/Mdyn~1/1000), with rms of ~0.35 dex, similar to the MBH-sigma relation. Our results are consistent with previous determinations at shorter wavelengths. By using our calibrated M/L, we rescale MBH-Lbul to obtain the MBH-Mstar relation, which can be used as the local reference for high-z studies which probe the cosmic evolution of MBH-galaxy relations and where the stellar mass is inferred directly from luminosity measurements. The analysis of pseudobulges shows that 4 out of 9 lie on the scaling relations within the observed scatter, while those with small MBH are significantly displaced. We explore the different origins for such behavior, while considering the possibility of nuclear morphological components not reproduced by our two-dimensional decomposition.

description: We investigate the spectrum and wave functions of {\bar q}'q' bound states for heavy fourth generation quarks (q') that have a very small mixing with the three observed generations of standard model quarks. Such bound states come with different color, spin and flavor quantum numbers. Since the fourth generation Yukawa coupling, λ_{q'}, is large we include all perturbative corrections to the potential between the heavy quark and antiquark of order λ_{q'}^2N_c/16π^2 where N_c is the number of colors, as well as relativistic corrections suppressed by (v/c)^2. We find that the lightest fourth generation quark masses for which a bound state exists for color octet states. For the the color singlet states, which always have a bound state, we analyze the influence that the Higgs couplings have on the size and binding energy of the bound states.

description: We present an analysis of time-resolved, medium resolution optical spectroscopic observations of UX UMa in the blue (3920-5250 A) and red (6100-7200 A) wavelength ranges, that were obtained in April 1999 and March 2008 respectively. The observed characteristics of our spectra indicate that UX UMa has been in different states during those observations. The blue spectra are very complex. They are dominated by strong and broad single-peaked emission lines of hydrogen. The high-excitation lines of HeII 4686 and the Bowen blend are quite strong as well. All the lines consist of a mixture of absorption and emission components. Using Doppler tomography we have identified four distinct components of the system: the accretion disc, the secondary star, the bright spot from the gas stream/disc impact region, and the unique compact area of absorption in the accretion disc seen as a dark spot in the lower-left quadrant of the tomograms. In the red wavelength range, both the hydrogen (H_alpha) and neutral helium (HeI 6678 and HeI 7065) lines were observed in emission and both exhibited double-peaked profiles. Doppler tomography of these lines reveals spiral structure in the accretion disc, but in contrast to the blue wavelength range, there is no evidence for either the dark spot or the gas stream/disc impact region emission, while the emission from the secondary star is weak. During the observations in 1999, UX UMa showed many of the defining properties of the SW Sex stars. However, all these features almost completely disappeared in 2008. We have also estimated the radial velocity semi-amplitudes K_1 and K_2 and evaluated the system parameters of UX UMa. These estimates are inconsistent with previous values derived by means of analysis of WD eclipse features in the light curve in the different wavelength ranges.

description: We demonstrate that morphological observables (e.g. steepness of the radial light profile, ellipticity, asymmetry) are intertwined and cannot be measured independently of each other. We present strong arguments in favour of model-based parametrisation schemes, namely reliability assessment, disentanglement of morphological observables, and PSF modelling. Furthermore, we demonstrate that estimates of the concentration and Sersic index obtained from the Zurich Structure & Morphology catalogue are in excellent agreement with theoretical predictions. We also demonstrate that the incautious use of the concentration index for classification purposes can cause a severe loss of the discriminative information contained in a given data sample. Moreover, we show that, for poorly resolved galaxies, concentration index and M_20 suffer from strong discontinuities, i.e. similar morphologies are not necessarily mapped to neighbouring points in the parameter space. This limits the reliability of these parameters for classification purposes. Two-dimensional Sersic profiles accounting for centroid and ellipticity are identified as the currently most reliable parametrisation scheme in the regime of intermediate signal-to-noise ratios and resolutions, where asymmetries and substructures do not play an important role. We argue that basis functions provide good parametrisation schemes in the regimes of high signal-to-noise ratios and resolutions. Concerning Sersic profiles, we show that scale radii cannot be compared directly for profiles of different Sersic indices. Furthermore, we show that parameter spaces are typically highly nonlinear. This implies that significant caution is required when distance-based classificaton methods are used.

description: We find that a repulsive potential of graphene in the presence of a magnetic field has bound states that are peaked inside the barrier with tails extending over \ell(N + 1), where \ell and N are the magnetic length and Landau level(LL) index. We have investigated how these bound states affect scaling properties of the induced density of filled Landau levels of massless Dirac fermions. For chiral fermions we find, in strong coupling regime, that the density inside the repulsive potential can be greater than the value in the absence of the potential while in the weak coupling regime we find negative induced density. Similar results hold also for non-chiral fermions. As one moves from weak to strong coupling regimes the effective coupling constant between the potential and electrons becomes more repulsive, and then it changes sign and becomes attractive. Different power-laws of induced density are found for chiral and non-chiral fermions.

description: Design Science Research (DSR) has reached a significant impact on scholar’s research work around the globe in the information systems domain. DSR is an important IS research paradigm for creating descriptive and prescriptive knowledge concerning the artificial construction of today’s reality in the interrelation between the social and the technological sub-system. Various prior research has decisively defined and structured DSR in order to derive rigorously relevant contributions in terms of frameworks and methodologies. This paper contributes to this discourse from a research in action point of view by investigating critical activities within the design science phases and when passing from one to the next DSR cycle. For that purpose we elaborate critical DSR activities and demonstrate their effective execution along four DSR in action examples to provide guidance and best practices for design science projects seeking for rigor and relevance.

description: A comprehensive experimental analysis of spatio-temporal coupling effects inherent to the acousto-optic programmable dispersive filter (AOPDF) is presented. Phase and amplitude measurements of the AOPDF transfer function are performed using spatially and spectrally resolved interferometry. Spatio-temporal and spatio-spectral coupling effects are presented for a range of shaped pulses that are commonly used in quantum control experiments. These effects are shown to be attributable to a single mechanism: a group-delay--dependent displacement of the shaped pulse. The physical mechanism is explained and excellent quantitative agreement between the measured and calculated coupling speed is obtained. The implications for quantum control experiments are discussed.

description: In this paper we investigate wormhole and spherically symmetric solutions in 4D gravity plus a matter source consisting of a ghost scalar field with a sine-Gordon potential. For the wormhole solutions we also include the possibility of electric and/or magnetic charges. For both types of solutions we perform a linear stability analysis and show that the wormhole solutions are stable and that when one turns on the electric and/or magnetic field the solution remains stable. The linear stability analysis of the spherically symmetric solutions indicates that they can be stable or unstable depending on one of the parameters of the system. This result for the spherically symmetric solution is nontrivial since a previous investigation of 4D gravity plus a ghost scalar field with a $λϕ^4$ interaction found only unstable spherically symmetric solutions. Both the wormhole and spherically symmetric solutions presented here asymptotically go to anti-de-Sitter space-time.

title: An Investigation into the Relationship between Post Occupancy Behaviour and Energy Efficiency in Residential Buildings
Creators: name: Lemon, Ian Michael
Publisher: name: The University of East London
Year: 2018

description: This research investigated the relationship between post occupancy behaviour and energy efficiency in residential buildings. 

Occupants remain unique in their behaviour, understanding and beliefs relating to energy conservation in residential buildings. 

The assessment of the occupants’ behaviour and energy usage was achieved by investigating innovative energy efficient technologies that had been installed in a pilot case study. 

These technologies included Balco glazing system, air source heat pumps, voltage optimisation units, phase change material, thermodynamics, passivents, energy efficient boilers, solar panels and external structural insulation.

The study consisted  of 51 dwellings, based on 5 property types, including a  mixture of semi-detached houses British Iron and Steel Federation (BISF), semi-detached and mid terraced  bungalows and flats, all constructed in the south east of the UK  between 1950 -1970.

Behaviour traits of occupants along with energy usage were collected over a period of 2 years. Data was collected through questionnaires, before and after the energy efficient retrofitting works had been carried out, supported by interviews and random observations. 

The analysis concluded that the properties with the most significant reduction in gas usage (20.62%) were the British Iron and Steel Federation (BISF) properties. These properties were characterised by structural insulation, boilers and solar panels.  Furthermore, all the occupants living in this type of retrofitted property were employed. They were conversant with maintenance manuals and the use of the internet, familiar with the types of energy efficient technologies that had been fitted and they paid their energy bills by pre-payment card.

The outcomes of this investigation could further advance the research in the area of the energy retrofitted residential housing in order to maximise their energy efficiency based on occupants’ behaviour, matched against user-friendly technologies, thus supporting designers, management agents, manufactures as well as responding to the occupants’ needs.
Accretion and jet power in active galactic nuclei

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: The classical diagrams of radio loudness and jet power as a function of mass and accretion rate of the central spacetime singularity in active galactic nuclei are reanalyzed by including the data of the recently discovered powerful relativistic jets in Narrow-Line Seyfert 1 Galaxies. The results are studied in the light of the known theories on the relativistic jets, indicating that while the Blandford-Znajek mechanism is sufficient to explain the power radiated by BL Lac Objects, it fails to completely account the power from quasars and Narrow-Line Seyfert 1. This favors the scenario outlined by Cavaliere & D'Elia of a composite jet, with a magnetospheric core plus a hydromagnetic component emerging as the accretion power increases and the disc becomes radiation-pressure dominated. A comparison with Galactic compact objects is also performed, finding some striking similarities, indicating that as the neutron stars are the low-mass jet systems analogue of black holes, the Narrow-Line Seyfert 1 Galaxies are the low-mass counterpart of the blazars.

description: High energy photons from blazars can initiate electromagnetic pair cascades interacting with the extragalactic photon background. The charged component of such cascades is deflected and delayed by extragalactic magnetic fields (EGMF), reducing thereby the observed point-like flux and leading potentially to multi degree images in the GeV energy range. We calculate the fluence of 1ES 0229+200 as seen by Fermi-LAT for different EGMF profiles using a Monte Carlo simulation for the cascade development. The non-observation of 1ES 0229+200 by Fermi-LAT suggests that the EGMF fills at least 60% of space with fields stronger than {\cal O}(10^{-16}-10^{-15})G for life times of TeV activity of {\cal O}(10^2-10^4)yr. Thus the (non-) observation of GeV extensions around TeV blazars probes the EGMF in voids and puts strong constraints on the origin of EGMFs: Either EGMFs were generated in a space filling manner (e.g. primordially) or EGMFs produced locally (e.g. by galaxies) have to be efficiently transported to fill a significant volume fraction, as e.g. by galactic outflows.

Towards large-scale nonparametric scene parsing of images and video
Creators: name: Tung, Frederick
Publisher: name: University of British Columbia
Year: 2017

description: In computer vision, scene parsing is the problem of labelling every pixel in an image or video with its semantic category. Its goal is a complete and consistent semantic interpretation of the structure of the real world scene. Scene parsing forms a core component in many emerging technologies such as self-driving vehicles and prosthetic vision, and also informs complementary computer vision tasks such as depth estimation. This thesis presents a novel nonparametric scene parsing framework for images and video. In contrast to conventional practice, our scene parsing framework is built on nonparametric search-based label transfer instead of discriminative classification. We formulate exemplar-based scene parsing for both 2D (from images) and 3D (from video), and demonstrate accurate labelling on standard benchmarks. Since our framework is nonparametric, it is easily extensible to new categories and examples as the database grows. Nonparametric scene parsing is computationally demanding at test time, and requires methods for searching large collections of data that are time and memory efficient. This thesis also presents two novel binary encoding algorithms for large-scale approximate nearest neighbor search: the bank of random rotations is data independent and does not require training, while the supervised sparse projections algorithm targets efficient search of high-dimensional labelled data. We evaluate these algorithms on standard retrieval benchmarks, and then demonstrate their integration into our nonparametric scene parsing framework. Using 256-bit codes, binary encoding reduces search times by an order of magnitude and memory requirements by three orders of magnitude, while maintaining a mean per-class accuracy within 1% on the 3D scene parsing task.
Dark Matter and Synchrotron Emission from Galactic Center Radio Filaments

description: The inner degrees of the Galactic center contain a large population of filamentary structures observed at radio frequencies. These so-called non-thermal radio filaments (NRFs) trace magnetic field lines and have attracted significant interest due to their hard (S_v ~ -0.1 +/- 0.4) synchrotron emission spectra. The origin of these filaments remains poorly understood. We show that the electrons and positrons created through the annihilations of a relatively light (~5-10 GeV) dark matter particle with the cross section predicted for a simple thermal relic can provide a compelling match to the intensity, spectral shape, and flux variation of the NRFs. Furthermore, the characteristics of the dark matter particle necessary to explain the synchrotron emission from the NRFs is consistent with those required to explain the excess gamma-ray emission observed from the Galactic center by the Fermi-LAT, as well as the direct detection signals observed by CoGeNT and DAMA/LIBRA.

phase contrast

description: This thesis focuses on the development and optimization of Talbot grating interferometry for phase contrast imaging of laterally extended samples with high speed. This development is established by a theoretical description of the forward problem of image formation and the inverse problem of data retrieval, supported by numerical calculations and confirmed in exemplary experiments. The potential of two new developed instruments is demonstrated by a wide variety of imaging applications.

Acoustic signatures in the Cosmic Microwave Background bispectrum from primordial magnetic fields

description: Using the full radiation transfer function, we numerically calculate the CMB angular bispectrum seeded by the compensated magnetic scalar density mode. We find that, for the string inspired primordial magnetic fields characterized by index $n_B=-2.9$ and mean-field amplitude $B_{\lam}=9{\rm nG}$, the angular bispectrum is dominated by two primordial magnetic shapes. The first magnetic shape looks similar to the one from local-type primordial curvature perturbations, so both the amplitude and profile of the Komatsu-Spergel estimator (reduced bispectrum) seeded by this shape are almost the same as those of the primary CMB anisotropies. However, for different parameter sets ($l_1,l_2$), this "local-type" reduced bispectrum oscillates around different asymptotic values in the high-$l_3$ regime because of the effect of the Lorentz force, which is exerted by the primordial magnetic fields on the charged baryons. This feature is different from the standard case where all modes approach to zero asymptotically in the high-$l$ limit. On the other hand, the second magnetic shape appears only in the primordial magnetic field model. The amplitude of the Komatsu-Spergel estimator sourced by the second shape diverges in the low-$l$ regime because of the negative slope of shape. In the high-$l$ regime, this amplitude is approximately equal to that of the first estimator, but with a reversal phase.
