description: Using time-resolved x-ray diffraction, we demonstrate the manipulation of the picosecond strain response of a metallic heterostructure consisting of a dysprosium (Dy) transducer and a niobium (Nb) detection layer by an external magnetic field. We utilize the first-order ferromagnetic–antiferromagnetic phase transition of the Dy layer, which provides an additional large contractive stress upon laser excitation compared to its zerofield response. This enhances the laser-induced contraction of the transducer and changes the shape of the picosecond strain pulses driven in Dy and detected within the buried Nb layer. Based on our experiment with rare-earth metals we discuss required properties for functional transducers, which may allow for novel field-control of the emitted picosecond strain pulses.

description: Community Wireless Mesh Networks (WMN) is a paradigm in wireless communication of 21st centuary as means of providing high speed braodband access. Un-cooperative nodes, both selfish and malicious proves to be a significant threat in Community WMN that require a solution independent of routing protocols being used. We propose to implement Modified PIFA (MPIFA), an Improved version of Protocol Independent Fairness Algorithm (PIFA) proposed by Younghwan Yoo, Sanghyun and P. Agrawal [6] with ability to cater specific requirements in Community WMN. MPIFA has malicious nodes detection rate improvement of 50% when nodes demonstrate low probabilistic malicious behavior of 10% to circumvent the security measures in place. Improvements were also made to reduce false malicious node detections to 4% when node-to-node link failures occur in Community WMN.

Berufliche Gratifikationskrisen, vermarktlichte Arbeitsformen und Gesundheit - Eine Anwendung und Erweiterung des Modells beruflicher Gratifikationskrisen um vermarktlichte Arbeitsformen auf Basis des Sozio-oekonomischen Panels

description: Eine der vielfältigen Ursachen gesundheitlicher Ungleichheit stellt Erwerbsarbeit und die damit verbundenen Arbeitsbelastungen dar. Durch den Wandel der Arbeit in den letzten Jahrzehnten nahmen insbesondere psychische Anforderungen an die Beschäftigten zu. Dabei wird in der Forschung vermutet, dass dies u.a. ein Grund für den starken Anstieg der psychischen und Verhaltensstörungen in der Bevölkerung sind. Der Zusammenhang zwischen vermarktlichten Arbeitsformen und Gesundheit wurde jedoch in der bisherigen Forschung zumeist deskriptiv und somit nicht ausreichend erforscht. Die vorliegende Dissertation trägt dazu bei, diese Forschungslücke zu schließen, indem sie vermarktlichte Arbeitsformen zusammen mit einer bedeutenden Theorie zur Erklärung arbeitsbezogener Gesundheitsbelastungen untersuchte. Das Modell beruflicher Gratifikationskrisen nach Siegrist (1996) wurde zunächst anhand von quantitativen Methoden der empirischen Sozialforschung auf Basis des Sozio-oekonomischen Panels evaluiert und umstrukturiert. Die Revision der Theorie erfolgte mithilfe des Stressor-Detachment-Modells nach Sonnentag (2012). Hier konnte die besondere Rolle der psychologischen Distanzierungsfähigkeit von der Arbeit in Bezug auf die drei verwendeten Gesundheitsindikatoren herausgearbeitet werden: Beschäftigte, die besser von der Arbeit mental abschalten können, haben eine bessere psychische sowie körperliche Gesundheit sowie sind zufriedener mit dieser. Ferner wurde das überarbeitete Modell beruflicher Gratifikationskrisen um eine soziale Komponente ergänzt, die in einem Zusammenhang mit der psychischen Gesundheit stand. Auf Basis einer Klassifikation von vermarktlichten Arbeitsformen konnte daraufhin gezeigt werden, dass für vermarktlichte Beschäftigte, auf die u.a. flexible Arbeitszeiten, eine Gewinnbeteiligung sowie Leistungsbewertung zutrifft und die eher die obere Statusgruppe repräsentieren, das mentale Abschalten von der Arbeit eine besondere Rolle spielt. Zusätzlich wurden in dieser Dissertation untere Statusgruppen in Form von erwerbsprekär Beschäftigten betrachtet und somit ein doppelter Beitrag zur Ungleichheitsforschung geleistet. Erwerbsprekarität und insbesondere das Auftreten multipler Prekaritätsdimensionen hatte einen negativen Effekt auf die Gesundheit, der jedoch nur geringfügig durch die Beschäftigung vorhergesagt wurde. Durch die Verknüpfung gesundheits- und arbeitssoziologischer Forschung aus Ungleichheitsperspektive konnten somit neue Erkenntnisse über die Zusammenhänge von Arbeitsbedingungen und Gesundheit gewonnen werden, die eine Basis für die zukünftige Forschung (bestenfalls) im Längsschnitt darstellen kann.

description: Earthworks on the Northwest Coast have been an enigma to archaeologi s ts since they were first discovered in 1857. Extensive field research conducted by the author in the summer of 1968 casts additional light on previous records. Sixty-four reports of earthworks were collected and over thirty sites visited. Two earthworks - -D eRt 41 and DfSg 3- -were test-excavated. Where possible, sites were contour mapped and photographed. Carbon samples from DfSg 3 were submitted for Cl4 dating . Earthworks appear to have been frequent and widespread along the Straits of Georgia around the 13th century. The resemble each other in construction, setting, form and style. Apparently they were utilized in subsistence activities, not in warfare, as had been commonly conjectured.

A study of dietary and non-dietary factors of iron deficiency anemia in HIV-positive women
Creators: name: Shahvarani, Dani Ladan
Publisher: name: University of British Columbia
Year: 2009

description: Anemia is one of the most common co-morbidities in human immunodeficiency virus (HIV), where approximately 50% of cases are attributed to iron deficiency anemia (IDA). IDA results from chronic inadequate iron supply to the body, whether through increased losses or decreased iron availability. In HIV, iron metabolism is greatly disrupted due to direct impacts of the virus, and therefore, prevalence of IDA is greater as compared to other populations. Women are at particularly high risk due to decreased dietary iron intakes, and increased losses due to menstruation and pregnancy. This study set out to determine the prevalence of anemia, iron deficiency and IDA, associated risk factors, and dietary iron intake patterns in a sample of HIV-positive women. Moreover, a newly-designed dietary survey was assessed for its ability to predict iron status in this population. It was found that the majority of participants had sub-optimal dietary iron intakes, with most dietary iron obtained from grain products. Prevalence of anemia, ID, and IDA were 30%, 40%, and 16%, respectively. Predictors for IDA in this sample were immune status (CD4<200 cells/µL); regular menstruation pattern; and African ethnicity. Food insecurity was quite prevalent among participants of Aboriginal and African ethnicity, with food bank use predominating as the main means of food assistance. Routine screening of iron status parameters, implementation of multivitamin use among all women with HIV, and dietary education regarding iron food sources is necessary to eliminate IDA in this population. Women with HIV should be engaged in self-management of their nutritional health, and community programs should be established that foster educational opportunities, rather than solely providing emergency food assistance.

description: In recent years more and more long-term broadband data sets are collected in geosciences. Therefore there is an urgent need of algorithms which semi-automatically analyse and decompose these data into separate periods which are associated with different processes. Often Fourier and Wavelet Transform is used to decompose the data into short and long period effects but these fail often because of their simplicity. In this paper we investigate the novel approaches Empircial Mode Decomposition and Sparse Decomposition for long-term sea floor pressure data analysis and compare them with the classical ones. Our results indicate that none of the methods fulfils all the requirements but Sparse Decomposition performed best except for computing efficiency.

Inverse semigroups determined by their partial automorphism monoids

description: The partial automorphism monoid of an inverse semigroup is an inverse monoid consisting of all isomorphisms between its inverse subsemigroups. We prove that a tightly connected fundamental inverse semigroup $S$ with no isolated nontrivial subgroups is lattice determined "modulo semilattices" and if $T$ is an inverse semigroup whose partial automorphism monoid is isomorphic to that of $S$, then either $S$ and $T$ are isomorphic or they are dually isomorphic chains relative to the natural partial order; a similar result holds if $T$ is any semigroup and the inverse monoids consisting of all isomorphisms between subsemigroups of $S$ and $T$, respectively, are isomorphic. Moreover, for these results to hold, the conditions that $S$ be tightly connected and have no isolated nontrivial subgroups are essential.

description: We study the in-plane and out-of-plane density ordering instabilities of quasi-two-dimensional fermionic polar molecules in single-layer and multi-layer configurations. We locate the soft modes by evaluating linear response functions within the conserving time-dependent Hartree-Fock (TDHF). The short-range exchange effects are taken into account by solving the Bethe-Salpeter integral equation numerically. An instability phase diagram is calculated for both single-layer and multi-layer systems and the unstable wave-vector is indicated. In all cases, the in-plane density wave instability is found to precede the out-of-plane instability. The unstable wave-vector is found to be approximately twice the Fermi wave-vector of one of the subbands at a time and can change discontinuously as a function of density and dipolar interaction strength. In multi-layer configurations, we find a large enhancement of density wave instability driven by dilute quasiparticles in the first excited subband. Finally, we provide a simple qualitative description of the phase diagrams using a RPA-like approach. Compared to previous works done within the RPA approximation, we find that inclusion of exchange interactions stabilize the normal liquid phase further and increase the critical dipolar interaction strength corresponding to the onset of density-wave instability by over a factor of two.

description: The topic of this Ph.D. thesis is the analysis of the wake and the effectiveness of the propeller of manoeuvring ships. The wake of drifting and yawing ships was determined with the help of RANS-CFD-methods. By analysing the propeller in the effective wake the dependency of the effectiveness from manoeuvring states was identified. With this dependency a manoeuvring simulation was enhanced. Results were validated with model and full scale measurements.

description: Agile methodologies are current best practice in software development. They are favored for, among other reasons, preventing premature optimization by taking a somewhat short-term focus, and allowing frequent replans/reprioritizations of upcoming development work based on recent results and current backlog. At the same time, funding agencies prescribe earned value management accounting for large projects which, these days, inevitably include substantial software components. Earned Value approaches emphasize a more comprehensive and typically longer-range plan, and tend to characterize frequent replans and reprioritizations as indicative of problems. Here we describe the planning, execution and reporting framework used by the LSST Data Management team, that navigates these opposite tensions.

description: We investigate to what extent the recently measured value for a non-vanishing direct CP asymmetry in D0 -> K+ K- and D0 -> pi+ pi- decays can be accommodated in the Standard Model (SM) or extensions with a constrained flavour sector, for instance from a sequential 4th generation of quarks (4G). From the comparison with D0 -> K- pi+ branching ratios, we establish large U-spin symmetry (d s) breaking effects with large strong phases between different interfering amplitudes. On the basis of conservative estimates on amplitude ratios - which are supported by an analysis of the breaking of a (c u) symmetry in non-leptonic B0 decays - we find that, in the SM, direct CP asymmetries in the pi+ pi- or K+ K- modes (or in their difference) of the order of several per mille are still plausible. Due to the constraints on the new CP phases in the 4G model, only moderate effects compared to the SM estimates are possible. We suggest CP studies at LHCb as well as at (Super)B-factories of several distinctive modes, such as D+ -> Kbar(*)0 pi+, phi pi+ and Ds -> K(*)0 pi+, phi pi+ (K+) etc., which should shed more light on the short- and long-distance issues underlying CP violation in non-leptonic D-meson decays.

description: The dominant non-instrumental background source for space-based infrared observatories is the zo- diacal light. We present Spitzer Infrared Array Camera (IRAC) measurements of the zodiacal light at 3.6, 4.5, 5.8, and 8.0 μm, taken as part of the instrument calibrations. We measure the changing surface brightness levels in approximately weekly IRAC observations near the north ecliptic pole (NEP) over the period of roughly 8.5 years. This long time baseline is crucial for measuring the annual sinusoidal variation in the signal levels due to the tilt of the dust disk with respect to the ecliptic, which is the true signal of the zodiacal light. This is compared to both Cosmic Background Explorer Diffuse Infrared Background Experiment (COBE DIRBE) data and a zodiacal light model based thereon. Our data show a few percent discrepancy from the Kelsall et al. (1998) model including a potential warping of the interplanetary dust disk and a previously detected overdensity in the dust cloud directly behind the Earth in its orbit. Accurate knowledge of the zodiacal light is important for both extragalactic and Galactic astronomy including measurements of the cosmic infrared background, absolute measures of extended sources, and comparison to extrasolar interplanetary dust models. IRAC data can be used to further inform and test future zodiacal light models.

The Banff-Bow Valley : environmental conflict, wildlife management and movement
Creators: name: Dickmeyer, Laurie
Publisher: name: University of British Columbia
Year: 2009

description: The Banff-Bow Valley has been a site of environmental conflict since the creation of Banff National Park (BNP) in 1887. The study of national parks reveals what and how people conceive of nature. Wildlife management also reveals how people have thought about nonhumans throughout the history of the park. Initially, BNP was viewed as a health spa and in economic terms. This view expanded to include an appreciation for scenery and wild animals, which were considered “game” or “noxious” and “pests.” Science, attitudes and perceptions influenced management practices, and beginning in the 1960s and 1970s, ecological thinking gained prominence. At the same time, the environment and acceptable human use and development of the landscape became contentious issues. Parks Canada attempted to include public participation processes in their management planning but were mostly met with criticism. In 1994, conflicts over the doubling of the Trans Canada Highway (TCH) and threats to the park’s World Heritage status led the federal government to inaugurate the Banff-Bow Valley Study (BBVS), which was to assess, independently of Parks Canada, the state of the valley and provide management recommendations. The two-year, $2 million study determined that “ecological integrity” was being threatened by heavy human use. The study’s Task Force provided approximately 500 specific recommendations. This work describes the BBVS process, its public reception and Park Canada’s reaction to the Task Force’s findings. In conclusion, the topic of wildlife movement and corridors is explored further. This work asks how humans should live with wildlife in BNP, especially since some of these nonhuman animals are predators. Science cannot provide the answer to this question to make management decisions. Rather, we look to thinking on nonhuman movement in the social sciences, which point to a more flexible and respectful vision of human and nonhuman coexistence.

Shallowed cusp slope of dark matter in disc galaxy formation through clump clusters

description: Cusp-core problem is a controversial problem on galactic dark matter haloes. Cosmological N-body simulations has demonstrated that galactic dark matter haloes have a cuspy density profile at the centre. However, baryonic physics may affect the dark matter density profile. For example, it was suggested that adiabatic contraction of baryonic gas makes the dark matter cusp steeper. However, it is still an open question if the gas falls into the galactic centre in smooth adiabatic manner. Recent numerical studies suggested that disc galaxies might experience clumpy phase in their early stage of the disc formation, which could also explain clump clusters and chain galaxies observed in high redshift Universe. In this letter, using numerical simulations with an isolated model, we study how the dark matter halo responds to these clumpy nature of baryon component in disc galaxy formation through the clump cluster phase. Our simulation demonstrates that such clumpy phase leads to a shallower density profile of the dark matter halo in the central region while clumps fall into the centre due to dynamical friction. This mechanism helps to make the central dark matter density profile shallower in the galaxies whose virial mass is as large as 5.0*10^11 solar masses. This phenomenon is caused by reaction to dynamical friction of the stellar clumps against the dark matter halo. The halo draws the clumps into the galactic centre, while kinematically heated by the clumps. We additionally run a dark matter only simulation excluding baryonic component and confirm that the resultant shallower density profile is not due to numerical artifact in the simulation, such as two-body relaxation.

description: The multi-wavelength anomalous diffraction (MAD) method is used to determine phase information in x-ray crystallography by employing dispersion corrections from heavy atoms on coherent x-ray scattering. X-ray free-electron lasers (FELs) show promise for revealing the structure of single molecules or nanocrystals within femtoseconds, but the phase problem remains largely unsolved. Due to the ultrabrightness of x-ray FEL, samples experience severe electronic radiation damage, especially to heavy atoms, which hinders direct implementation of the MAD method with x-ray FELs. We propose a generalized version of the MAD phasing method at high x-ray intensity. We demonstrate the existence of a Karle--Hendrickson-type equation for the MAD method in the high-intensity regime and calculate relevant coefficients with detailed electronic damage dynamics of heavy atoms. Our results show that the bleaching effect on the scattering strength of the heavy atoms can be advantageous to the phasing method. The present method offers a potential for \textit{ab initio} structural determination in femtosecond x-ray nanocrystallography.

description: Der Verbund zwischen Bewehrung und Beton bestimmt das Trag- und Verformungsverhalten von Stahlbetontragwerken. Anhand von Versuchen wird die Ermüdung des Verbundes und der Mitwirkung des Betons zwischen den Rissen untersucht. Daraufhin werden Berechnungsmodelle vorgeschlagen, um das mechanische Verhalten von Zuggurten und die Neigung von Druckstreben in Stahlbetonbalken unter Ermüdungsbeanspruchung zu ermitteln.
description: The bond between reinforcement and concrete determines the carrying and deformation capacity of concrete structures. Based on performed tests, the fatigue of bond and the subsequent degradation of the tension-stiffening effect are investigated. As a result, calculation models are proposed in order to describe the mechanical behaviour of tension chords and the inclination of compression struts in concrete beams under fatigue loading.

description: The evolved carbon-rich AGB star IRC +10216 (CW Leo) is the brightest mid-infrared source outside the solar system, as well as one of the closest examples of an evolved star losing mass. It has a complex and variable circumstellar structure on small scales in the near-IR, and mid-IR interferometry has revealed a dynamic dust formation zone. We have obtained diffraction limited imaging and grism spectroscopy of IRC +10216 at the 6.5m MMT in the N-band (~8-13 microns). These new observations show that a change has occurred in the dust shell surrounding IRC +10216 over the last two decades, which is illustrated by a change in the apparent shape of the well known SiC spectral feature at ~11 microns and a reduction in the continuum at 13 microns. As expected, our diffraction limited spatial information shows an extended circumstellar envelope. We also demonstrate that the dusty envelope appears to be ~30% larger at the wavelengths of the SiC feature, likely due to the increased opacity of SiC. The deconvolved FWHM of the object increases from 0.43" (~56 AU) for wavelength < 10 microns to 0.58" (~75 AU) at 11.8 microns, then decreases to 0.5" (~65 AU) at 12.7 microns. Our estimates of IRC +10216's size allow us to plausibly tie the change in the spectrum over the last 12.5 years to the evolution of the dusty circumstellar envelope at speeds of 12-17 km/sec.

description: Transversity distribution describes the quark transverse polarization inside a transversely polarized nucleon. It is the less known leading-twist piece of the QCD description of the partonic structure of the nucleon. Transversity can be extracted from semi-inclusive deep inelastic scattering (SIDIS) where, however, it couples to a new, unknown fragmentation function, called Collins function. We present the preliminary results of the measurement of the azimuthal asymmetries in the process e^+e^- -> qqbar -> pi pi X, where the two pions are produced in opposite hemispheres. These preliminary results are based on a data sample of about 45 fb^{-1}, collected by the BABAR experiment at a center-of-mass energy of 10.54 GeV, and are compared with the Belle measurements.

description: A variety of neurodegenerative diseases are associated with the formation of amyloid plaques. Our incomplete understanding of this process underscores the need to decipher the principles governing protein aggregation. Most experimental and simulation studies have been interpreted largely from the perspective of proteins: the role of solvent has been relatively overlooked. In this Account, we provide a perspective on how interactions with water affect folding landscapes of A$β$ monomers, A$β_{16-22}$ oligomer formation, and protofilament formation in a Sup35 peptide. Simulations show that the formation of aggregation-prone structures (N$^*$) similar to the structure in the fibril requires overcoming high desolvation barrier. The mechanism of protofilament formation in a polar Sup35 peptide fragment illustrates that water dramatically slows down self-assembly. Release of water trapped in the pores as water wires creates protofilament with a dry interface. Similarly, one of the main driving force for addition of a solvated monomer to a preformed fibril is the entropy gain of released water. We conclude by postulating that two-step model for protein crystallization must also hold for higher order amyloid structure formation starting from N$^*$. Multiple N$^*$ structures with varying water content results in a number of distinct water-laden polymorphic structures. In predominantly hydrophobic sequences, water accelerates fibril formation. In contrast, water-stabilized metastable intermediates dramatically slow down fibril growth rates in hydrophilic sequences.

description: A small, bimetallic particle in a hydrogen peroxide solution can propel itself by means of an electrocatalytic reaction. The swimming is driven by a flux of ions around the particle. We model this process for the presence of a monovalent salt, where reaction-driven proton currents induce salt ion currents. A theory for thin diffuse layers is employed, which yields nonlinear, coupled transport equations. The boundary conditions include a compact Stern layer of adsorbed ions. Electrochemical processes on the particle surface are modeled with a first order reaction of the Butler-Volmer type. The equations are solved numerically for the swimming speed. An analytical approximation is derived under the assumption that the decomposition of hydrogen peroxide occurs mainly without inducing an electric current. We find that the swimming speed increases linearly with hydrogen peroxide concentration for small concentrations. The influence of ion diffusion on the reaction rate can lead to a concave shape of the function of speed vs. hydrogen peroxide concentration. The compact layer of ions on the particle diminishes the reaction rate and consequently reduces the speed. Our results are consistent with published experimental data.
Synchrotron and inverse-Compton emission from blazar jets I: a uniform conical jet model

description: In the first of a series of papers investigating emission from blazar jets from radio to high-energy γ-rays, we revisit the class of models where the jet has a uniform conical ballistic structure. We argue that by using simple developments of these models, in the context of new multi-frequency data extending to gamma-ray energies, valuable insights may be obtained into the properties that fully realistic models must ultimately have. In this paper we consider the synchrotron and synchrotron-self-Compton emission from the jet, modelling the recent simultaneous multi-wavelength observations of BL Lac. This is the first time these components have been fitted simultaneously for a blazar using a conical jet model. In the model we evolve the electron population dynamically along the jet taking into account the synchrotron and inverse-Compton losses. The inverse-Compton emission is calculated using the Klein-Nishina cross section and a relativistic transformation into the jet frame, and we explicitly show the seed photon population. We integrate synchrotron opacity along the line of sight through the jet plasma, taking into account the emission and opacity of each section of the jet. In agreement with previous studies of radio emission, we find that a conical jet model which conserves magnetic energy produces the characteristic blazar flat radio spectrum, however, we do not require any fine-tuning of the model to achieve this. Of particular note, in our model fit to BL Lac--which at ~10^37W is a relatively low jet-power source--we find no requirement for significant re-acceleration within the jet to explain the observed spectrum.

description: We have selelcted 556 Red Horizontal Branch (RHB) stars along the streams of the Sagittarius dwarf galaxy (Sgr) from SDSS DR7 spectroscopic data using a theoretical model. The metallicity and α-elements distributions are investigated for stars in the Sgr streams and for Galactic stars at the same locations. We find that the Sgr stars have two peaks in the metallicity distribution while the Galactic stars have a more prominent metal-poor peak. Meanwhile, [α/Fe] ratios of the Sgr stars are lower than those of the Galactic stars. Among the Sgr stars, we find a difference in the metallicity distribution between the leading and trailing arms of the Sgr tidal tails. The metallicity and [α/Fe] distribution of the leading arm is similar to that of the Galaxy. The trailing arm is composed mainly of a metal rich component and [α/Fe] is obviously lower than that of the Galactic stars. The metallicity gradient is -(1.8 \pm 0.3)\times10^{-3} dex degree^{-1} in the first wrap of the trailing arm and -(1.5 \pm 0.4)\times10^{-3} dex degree^{-1} in the first wrap of the leading arm. No significant gradient exists along the second wraps of the leading or trailing arms. It seems that the Sgr dwarf galaxy initially lost the metal poor component in the second wrap (older) arms due to the tidal force of our Galaxy and then the metal rich component is disrupted in the first wrap (younger) arms. Finally, we found that the velocity dispersion of the trailing arm from 88^\circ

description: Universal role of the nonlinear one-third subharmonic resonance mechanism in generation of the strong fluctuations in such complex natural dynamical systems as global climate and global solar activity is discussed using wavelet regression detrended data. Role of the oceanic Rossby waves in the year-scale global temperature fluctuations and the nonlinear resonance contribution to the El Nino phenomenon have been discussed in detail. The large fluctuations of the reconstructed temperature on the millennial time-scales (Antarctic ice cores data for the past 400,000 years) are also shown to be dominated by the one-third subharmonic resonance, presumably related to Earth precession effect on the energy that the intertropical regions receive from the Sun. Effects of Galactic turbulence on the temperature fluctuations are discussed in this content. It is also shown that the one-third subharmonic resonance can be considered as a background for the 11-years solar cycle, and again the global (solar) rotation and chaotic propagating waves play significant role in this phenomenon. Finally, a multidecadal chaotic coherence between the detrended solar activity and global temperature has been briefly discussed.
