description: The unrelenting incidence of obesity and type 2 diabetes has become a global public health concern. Cardiovascular disease (CVD) remains the leading cause of morbidity and mortality in these cohorts. Cardiovascular Magnetic Resonance (CMR) imaging is a robust imaging modality with techniques to provide sensitive detection of early cardiovascular changes in obesity and diabetes. In a prospective study of obese adolescents (n=11, 10 to 20 years old) and a healthy weight control group (n=14), we found obesity was associated with increases in Left ventricular (LV) mass, LV wall thickness and mass:volume ratio. In this “early stage” of remodeling, these structural changes were not associated with elevations in Native T1, a surrogate marker of tissue fibrosis. Strain analysis, by novel CMR tissue tracking analysis, revealed a hyper-contractile state, likely representing a combined contribution of elevated systolic blood pressure with compensatory myocyte hypertrophy. Obese subjects were additionally enrolled in a comprehensive 6-month lifestyle intervention; subjects did not experience weight loss or any change in cardiac parameters after 6 months. Further along the natural history of CVD as related to metabolic disease, the second study looked to examine possible sub-clinical changes in the hearts of otherwise healthy diabetic patients. This study examined twenty-eight healthy type 2 diabetic patients without any observable vascular complications. The complementary use of CMR-based T1 mapping and 3-dimensional strain analysis demonstrated expansion of the extracellular matrix and a reduction in global longitudinal strain. In the endpoint of the cardiometabolic disease spectrum, we analyzed individuals with known or suspected Coronary Artery Disease. This study explored the relationship between intra-thoracic fat volume (ITFV) and 4D myocardial strain-based markers of adverse remodeling. In non-infarcted myocardium, ITFV is associated with reductions in myocardial strain. These findings suggest ITFV to be a potentially important marker of adverse ventricular remodeling. The findings of these three studies suggest a capacity of contemporary CMR to identify early changes in cardiometabolic disease and also lend insight into the progression of diabetic heart disease. CMR provides a non-invasive, accurate and reproducible imaging modality with the potential to be useful in screening and CVD risk-stratification.
Crosslinked biopolymer bundles: crosslink reversibility leads to cooperative binding/unbinding phenomena

description: We consider a biopolymer bundle consisting of filaments that are crosslinked together. The crosslinks are reversible: they can dynamically bind and unbind adjacent filament pairs as controlled by a binding enthalpy. The bundle is subjected to a bending deformation and the corresponding distribution of crosslinks is measured. For a bundle consisting of two filaments, upon increasing the bending amplitude, a first-order transition is observed. The transition is from a state where the filaments are tightly coupled by many bound crosslinks, to a state of nearly independent filaments with only a few bound crosslinks. For a bundle consisting of more than two filaments, a series of first-order transitions is observed. The transitions are connected with the formation of an interface between regions of low and high crosslink densities. Combining umbrella sampling Monte Carlo simulations with analytical calculations, we present a detailed picture of how the competition between crosslink shearing and filament stretching drives the transitions. We also find that, when the crosslinks become soft, collective behavior is not observed: the crosslinks then unbind one after the other leading to a smooth decrease of the average crosslink density.

Des del punt de vista terminològic no és gens fàcil desentrellar el sentit del títol d’aquest escrit, perquè a primer raig ensopeguem amb un gran equívoc. La dificultat rau en el fet que el verb “amar” (o el seu equivalent “estimar”) i, sobretot, el substantiu “amor” són polisèmics. Sembla, d’antuvi, que tots intuïm el mateix quan emprem les paraules “amor” i “estimar”. La realitat, però, és ben diferent, perquè “amor” pot significar moltes coses, que no sempre conjuminen. En la semàntica de l’amor, cal avançar amb especial atenció i posar-hi moltíssima cura...

Concurrent effects of landscape context and managed pollinators on wild bee communities and canola (Brassica napus L.) pollen deposition

subject: Landscape

description: Both wild and managed bees can provide crop pollination, yet agricultural intensification has led to an increasing dependence on managed crop pollinators and the conversion of semi-natural areas to cultivated cropland, both of which affect the floral resources available to wild bees. Canola fields in southern Alberta were sampled for managed and wild bees, and landscape within a 3 km radius was classified. Abundance and diversity of wild bees, as well as pollen deposition in canola varied positively with the area of adjacent semi-natural habitat. Yet the effects of managed bees and landscape context were found to interact such that abundance of wild bees in landscapes with more semi-natural land declined more strongly over time with increased abundance of managed bees. Canola crops in more natural landscapes may have enhanced yields, but also greater impacts on wild-bee assemblages where managed bees are employed.

description: We investigate half-vortex sheets and domain-wall trains of rotating two-component Bose-Einstein condensates in spin-dependent optical lattices. The two-component condensates undergo phase separation in the form of stripes arranged alternatively. The vortices of one component are aligned in lines in the low-density regions and filled with the other component, which results in a stable vortex configuration, straight half-vortex sheets. A train of novel domain walls, with spatially periodic "eyebrow-like" spin textures embedded on them, are formed at the interfaces of the two components. We reveal that these spatially periodic textures on the domain walls result from the linear gradient of the relative phase, which is induced by the alternating arrangement of the vortex sheets in the two components. An accurate manipulation of the textures can be realized by adjusting the intercomponent interaction strength, the rotating angular frequency and the period of the optical lattices.

description: The subject of this dissertation is the cession of peculiar “property" rights under private law in the Ionian Islands –Corfu, Zakynthos and Kefalonia specifically– from the end of the 15th to the 18th century. In contrast to the modern right of ownership, the “property” rights under consideration granted certain broad or limited powers and freedoms over the land under specific contractual obligations. The first chapter highlights the main issues relating to the history of the Roman and Byzantine institution of emphyteusis, since this contract, perpetual in nature and providing the emphyteuta with a broad right, constitute a point of reference for the interpretation of the cessions under consideration in the related literature. The main part of the work consists of three chapters –one for each island– which are further divided into sections. In each section, a different contract is examined: the “soldiatiko”, the “syngrateia” and the contracts with duty to develop the land from Corfu, the “libello” and the “sembria” from Zakynthos and, finally, the “paktosis” from Kefalonia. The sources used are notarial documents included in published notarial registers or published collections of documents. Regarding the methodology, emphasis is placed on the analysis of the contract and the legal assessment of the right it cedes

description: We have investigated the 2009 July impact event on Jupiter using the ZEUS-MP 2 three-dimensional hydrodynamics code. We studied the impact itself and the following plume development. Eight impactors were considered: 0.5 km and 1 km porous (ρ= 1.760 g cm^{-3}) and non-porous (ρ= 2.700 g cm^{-3}) basalt impactors, and 0.5 km and 1 km porous (ρ= 0.600 g cm^{-3}) and non-porous ρ= 0.917 g cm^{-3}) ice impactors. The simulations consisted of these bolides colliding with Jupiter at an incident angle of θ= 69 degrees from the vertical and with an impact velocity of v = 61.4 km s^{-1}. Our simulations show the development of relatively larger, faster plumes created after impacts involving 1 km diameter bodies. Comparing simulations of the 2009 event with simulations of the Shoemaker-Levy 9 events reveals a difference in plume development, with the higher incident angle of the 2009 impact leading to a shallower terminal depth and a smaller and slower plume. We also studied the amount of dynamical chaos present in the simulations conducted at the 2009 incident angle. Compared to the chaos of the SL9 simulations, where θis approximately 45 degrees, we find no significant difference in chaos at the higher 2009 incident angle.

Reducing occupant injury in rear-end collisions through the implementation of energy-absorbing foam to the seat base
Creators: name: Mansour, Rami
Publisher: name: University of British Columbia
Year: 2011

description: Rear-end collisions account for approximately $9 billion in medical and damaged property costs annually in the United States alone. These types of collisions account for nearly 30% of all vehicle impacts, making them the most common collision type. Soft tissue injury to the neck (i.e., “whiplash”) is typically associated with this type of collision. The vehicle seating system is the predominant safety device employed to protect the occupant during a rear-end collision. Currently, designers focus predominantly on seat base strength, seat back stiffness/compliance, and head restraint size and position as a means of mitigating injury. While all of these aspects are important and have increased the crashworthiness of the seat, the concept of utilizing the seat base as a component to further assist in whiplash protection has remained relatively unexamined. The addition of a supplemental safety system to the seat base may offer the potential for reducing injuries in higher severity collisions. This thesis examines the potential for deformable materials, (in this study energy-absorbing foam), to absorb transmitted energy to the vehicle seat in order to reduce the dynamic loading experienced by the occupant. The relationships between the type and geometry of the foam and occupant dynamics, and how they affect potential occupant injury (as assessed using selected neck injury criteria) are assessed and reported. Several energy-absorbing foams currently available have been investigated in order to determine the best foam type and geometry for a range of collision speeds. The results indicate that the time to completely crush the foam, dictated by foam relative density, stress vs. strain behavior, foam geometry, and acceleration pulse, can affect the degree to which injury potential is reduced for a large range of collision speeds. Further discussions of design considerations for implementation of such a supplemental system are also provided in this thesis. Reducing rear-end collision severity with the implementation of this device can potentially lead to a decrease in rear-end collision induced injury and fatality.

description: Literature suggests that children placed in kinship care achieve positive outcomes. Literature also suggests the experience for kinship caregivers is very different from adoption and foster care; however assessment practice and policy do not reflect these unique elements. Using thematic analysis of secondary qualitative data, this study discusses crucial elements required for kinship care home assessments in Alberta. These elements which influence the practitioner, process, policy, legislation and systemic issues can then be used to inform kinship home assessment practice, policy and legislation. By using secondary data analysis, this study endeavored to honour the voices of people who have already shared their perspectives at public consultations and information gathering events sponsored by the Government of Alberta. An anti-colonizing lens and critical ecological framework ground this research in an approach that is sensitive to the impacts of structural colonization on Indigenous children and families through child welfare practice, policy and legislation.

description: La Historia de la Humanidad es una secuencia de acontecimientos que alternan experiencias de paz y violencia, de justicia e injusticia, de sufrimiento y reconciliación. A pesar de ello, predomina excesivamente una historia de guerras, tiranías y genocidios, que sobredimensiona la violencia como motor de la historia y predispone la sociedad a continuar por el mismo camino al no conocer alternativas. En cambio, la Historia de la Humanidad contiene una rica tradición de episodios de paz, noviolencia y reconciliación que han propulsado innumerables avances de la civilización humana, especialmente en términos de solidaridad social y de progreso moral. Este artículo reivindica la urgencia de revelar la Historia de la Paz a través del análisis de tres casos emblemáticos de construcción de la paz y de integración social durante el siglo XX: la reconciliación moral de Alemania tras sus trágicos episodios de guerra y genocidio, la lucha por los derechos civiles en Estados Unidos promovida por Martin Luther King y la reconciliación socio-política en Sudáfrica bajo el liderazgo inspirador de Nelson Mandela.

description: Solid oxide fuel cells are highly efficient electricity producing systems. This thesis examines the characteristic of the resulting carbon accumulation on the solid oxide fuel cell anode from reformate fuels. The two reformate fuels examined are based on the steam reforming of natural gas and diesel. The solid oxide fuel cell anodes tested are the standard Ni/YSZ anode and the standard Ni/YSZ anode impregnated with 5% barium oxide. The response of the anodes to the fuel was characterized using cyclic voltammetry, electrochemical impedance spectroscopy, temperature-programmed oxidation and scanning electron microscopy. The power curves of the diesel and natural gas reformate were largely similar to each other when compared to the performance in dry hydrogen. Changes in fuel did lead to changes in the amount and type of accumulated carbon. The natural gas reformate fuel as a whole accumulated less carbon than the diesel reformate.

description: Motivated by experiments on the archetypal frustrated magnet SrCr$_{9p}$Ga$_{12-9p}$O$_{19}$ (SCGO), we study the classical Heisenberg model on the pyrochlore slab (Kagomé bilayer) lattice with site-dilution $x=1-p$. This allows us to address generic aspects of the physics of non-magnetic vacancies in a classical spin liquid. We explicitly demonstrate that the pure ($x=0$) system remains a spin-liquid down to the lowest temperatures, with an unusual {\em non-monotonic} temperature dependence of the susceptibility, which even turns diamagnetic for the apical spins between the two kagome layers. For $x> 0$ but small, the low temperature magnetic response of the system is most naturally described in terms of the properties of spatially extended spin textures that cloak an "orphan" $S=3/2$ Cr$^{3+}$ spin in direct proximity to a pair of missing sites belonging to the same triangular simplex. In the $T \rightarrow 0$ limit, these orphan-texture complexes each carry a net magnetization that is exactly half the magnetic moment of an individual spin of the undiluted system. Furthermore, we demonstrate that they interact via an entropic {\em temperature dependent} {\em pair-wise exchange interaction} $J_{eff}(T,\vec{r}) \sim T {\mathcal J} (\vec{r} \sqrt{T})$ that has a logarithmic form at short-distances and decays exponentially beyond a thermal correlation length $ξ(T) \sim 1/\sqrt{T}$. The sign of $J_{eff}$ depends on whether the two orphan spins belong to the same Kagome layer or not. We provide a detailed analytical account of these properties using an effective field theory approach specifically tailored for the problem at hand. These results are in quantitative agreement with large-scale Monte Carlo numerics.

description: In single particle coherent x-ray diffraction imaging experiments, performed at x-ray free-electron lasers (XFELs), samples are exposed to intense x-ray pulses to obtain single-shot diffraction patterns. The high intensity induces electronic dynamics on the femtosecond time scale in the system, which can reduce the contrast of the obtained diffraction patterns and adds an isotropic background. We quantify the degradation of the diffraction pattern from ultrafast electronic damage by performing simulations on a biological sample exposed to x-ray pulses with different parameters. We find that the contrast is substantially reduced and the background is considerably strong only if almost all electrons are removed from their parent atoms. This happens at fluences of at least one order of magnitude larger than provided at currently available XFEL sources.

The approach is based on the new form of kinetic equations in terms of the internal and modified free energy. It is illustrated by a model example of a solid with vacancies, for which there is a complete statistical ground. The approach is applied to the description of important practical problem - the formation of fine-grained structure of metals during their treatment by methods of severe plastic deformation. In the framework of two-level two-mode effective internal energy potential model the strengthening curves unified for the whole of deformation range and containing the Hall-Petch and linear strengthening sections are calculated.

description: A novel Mg-6.2Gd-4.2Sm-1.2Zn alloy with a superior strength-ductility combination was achieved by traditional extrusion process and aging. Based on the characteristics of substitutional solution among rare earth (RE) elements, the Sm substitute part Gd element change the morphology of the LPSO phase, and the volume fraction of the 14H-LPSO phase increases, leading to a finer size and more dispersed distribution. Meanwhile, the Sm addition reduces the level of GB segregation of Zn and Gd, which further affects the precipitation of nano-precipitates during aging. The results offer insight into determining the precipitation behavior of second phases via regulating solute GB segregation. The mechanism of Sm substitute Gd element leads to the microstructure evolution in as-extruded Mg-Zn-Gd alloy is clarified.The dynamic precipitation process of β′ phase can be effectively promoted with Sm addition.The interaction mechanism among Zn/Gd/Sm co-segregation in GB and nano-phase precipitation behavior are completely revealed.The significantly strength increment of Mg alloys are significantly enhanced by Sm modification.

description: The violent events of the 20th century are not only part of history but also part of the identities and memories of many survivors, perpetrators, by-standers and their family members. After fascist and dictatorial regimes, mass-violence events and genocides, many scholars have raised the question of what has been done and how should the memories of such violent events be preserved, and their role in present day European countries. This paper explores the different approaches to historical memory and reconciliation in Spain after the Spanish Civil War and Francoist Repression and in Germany after the Holocaust. These two countries have been regarded as opposed models for historical memory: while Germany remains as the ‘paradigm’ of preservation of memory, Spain is often seen as the country of forgetting. Comparing the strategies undertaken by the governments of Spain and Germany can help understand the challenges and complexities of the preservation of historical memory after a traumatic historical event, as well as its influence on presentday national identities and politics.

description: We study probabilistic complexity classes and questions of derandomisation from a logical point of view. For each logic L we introduce a new logic BPL, bounded error probabilistic L, which is defined from L in a similar way as the complexity class BPP, bounded error probabilistic polynomial time, is defined from PTIME. Our main focus lies on questions of derandomisation, and we prove that there is a query which is definable in BPFO, the probabilistic version of first-order logic, but not in Cinf, finite variable infinitary logic with counting. This implies that many of the standard logics of finite model theory, like transitive closure logic and fixed-point logic, both with and without counting, cannot be derandomised. Similarly, we present a query on ordered structures which is definable in BPFO but not in monadic second-order logic, and a query on additive structures which is definable in BPFO but not in FO. The latter of these queries shows that certain uniform variants of AC0 (bounded-depth polynomial sized circuits) cannot be derandomised. These results are in contrast to the general belief that most standard complexity classes can be derandomised. Finally, we note that BPIFP+C, the probabilistic version of fixed-point logic with counting, captures the complexity class BPP, even on unordered structures.
Memoria de la Violencia, el Perdón y el Amor: Una Aproximación Filosófica

description: La memoria de un pasado violento y el perdón se entrelazan cuando se busca sanar dicho pasado, ya que el perdón se presenta ante nosotros como un elemento redentor y transformador, capaz de poner fin a espirales de violencia. Para tal propósito, el pasado tendrá que ser recordado adecuadamente, con veracidad e imparcialidad, de modo que el presente quede sanado y el futuro se llene de posibilidades. Ante la tentación de la venganza, habrá que fomentar un amor desde donde se decida amar y perdonar a los enemigos, lo cual permitirá que se desarmen esos temores que dieron lugar a la violencia pasada, ya que en el amor no hay temor.

description: Light transport in graded index media follows a curved trajectory determined by the Fermat's principle. Besides the effect of variation of the refractive index on the transport of radiative intensity, the curved ray trajectory will induce geometrical effects on the transport of polarization ellipse. This paper presents a complete derivation of vector radiative transfer equation for polarized radiation transport in absorption, emission and scattering graded index media. The derivation is based on the analysis of the conserved quantities for polarized light transport along curved trajectory and a novel approach. The obtained transfer equation can be considered as a generalization of the classic vector radiative transfer equation that is only valid for uniform refractive index media. Several variant forms of the transport equation are also presented, which include the form for Stokes parameters defined with a fixed reference and the Eulerian forms in the ray coordinate and in several common orthogonal coordinate systems.

description: Hetero-deformation induced (HDI) stress is crucial for the strengthening of heterostructured materials (HSMs), making its quantification essential for understanding the heterogeneous deformation mechanisms. We propose a novel method for measuring HDI stress based on plastic dissipation in hysteresis loops, offering superior accuracy and stability over previous methods, as demonstrated in studies on lamellar materials through experiments and FEM simulations. This approach advances a more objective, microstructure-based understanding of HDI stress in HSMs.

description: Let V be a finite-dimensional vector space over a field k and let W be a 1-dimensional k-vector space. Let < , >: V x V \to W be a symmetric bilinear form. Then < , > is called anisotropic if for all nonzero v \in V we have \neq 0. Motivated by a problem in algebraic number theory, we come up with a generalization of the concept of anisotropy to symmetric bilinear forms on finitely generated modules over artinian principal ideal rings. We will give many equivalent definitions of this concept of anisotropy. One of the definitions shows that one can check if a form is anisotropic by checking if certain forms on vector spaces are anisotropic. We will also discuss the concept of quasi-anisotropy of a symmetric bilinear form, which has no useful vector space analogue. Finally we will discuss the radical root of a symmetric bilinear form, which doesn't have a useful vector space analogue either. All three concepts have applications in algebraic number theory.

La rigenerazione urbana si basa su una visione integrata volta a risolvere i problemi urbani e a promuovere lo sviluppo delle comunità interessate. Reiventare lo spazio, valorizzare la cultura per dare nuova vita ai centri storici, è un’esigenza civica crescente e una sfida per i politici e i manager delle città. Questo obiettivo potrebbe essere raggiunto valorizzando il Patrimonio Culturale e i saperi locali per generare nuove opportunità e benessere per i cittadini. Al momento, troppo spesso il Patrimonio Culturale viene apprezzato principalmente a fini turistici. Un fatto che causa anche molteplici problemi: sovraffollamento, gentrificazione, conflitti tra interessi turistici e civici, traffico urbano, generazione di posti di lavoro a basso reddito, per citare solo i più evidenti. Ne deriva che una profonda comprensione della partecipazione civica e democratica nell'accesso, nella conservazione e nello sfruttamento del nostro Patrimonio Culturale è un terreno fertile per il dibattito tra studiosi di varie discipline. I contributi di questo libro cercano di alimentare tale dibattito dal punto di vista degli studiosi di management.

description: Refractory multi-principal-element alloys (RMPEAs) typically exhibit low strain hardening capacity and may even experience strain softening, which poses a risk to the structural integrity of materials. We first established that the strain softening observed in Ti1.5Al0.5ZrNb RMPEA is due to the planar slip of dislocations and the formation of narrow <111>{110} orientation dislocation channels (DCs). Subsequently, we introduced nanoscale ω-AlZr2 precipitates that are diffusely distributed around grain boundaries (GBs), which significantly enhance the strength and strain hardening capacity of the RMPEA by inhibiting the formation of narrow DCs. This approach is highly versatile and can effectively improve deformation stability.

description: We use data from the Wide-Field Infrared Survey Explorer (WISE) to perform a statistical study on the mid-infrared (IR) properties of a large number ($\sim10^2$) of BL Lac objects --- low-luminosity Active Galactic Nuclei (AGN) with a jet beamed toward the Earth. As expected, many BL Lac objects are so highly beamed that their jet synchrotron emission dominates their IR spectral energy distributions. In other BL Lac objects, however, the jet is not strong enough to completely dilute the rest of the AGN emission. We do not see observational signatures of the dusty torus from these weakly beamed BL Lac objects. The lack of observable torus emission is consistent with suggestions that BL Lac objects are fed by radiatively inefficient accretion disks. Implications for the "nature vs. nurture" debate for FR I and FR II radio galaxies are briefly discussed. Our study supports the notion that, beyond orientation, accretion rate plays an important role in AGN unification.
