description: Osteoarthritis (OA) is one of the most common chronic diseases worldwide which can lead to disability. There is a desperate need for the efficient and reliable detection of OA at the early stage when patients are likely to benefit most from disease interventions. It has been shown in previous studies that inflammation plays important roles in cartilage degeneration, synovitis, remodeling of the subchondral bone and pain. The purpose of this thesis was to determine if a panel of inflammatory cytokines were distinct within individuals with pre-radiographic OA and/or an increased risk of developing OA. Serum inflammatory profiles were analyzed within a number of patient cohorts [i.e., radiographic OA patients (hip and knee), youth with a history of intra-articular knee injury, corresponding controls]; and it was found that inflammatory profiles were distinct between knee vs. hip OA patients. Additionally, a computation method was developed which identified a coordinated change in cytokine profiles in the youth knee injury cohort. This computational methodology highlighted a number of candidate biomarkers that contributed to this observed difference, including C-C motif chemokine 22 (CCL22)/macrophage derived chemokine (MDC) which was selected for further study. In a pre-clinical rat OA model, it was found that CCL22 plays a functional role in chondrocyte apoptosis and cartilage degeneration. Further, it was found that CCL22 treated synovial fibroblasts demonstrated altered expression of inflammatory factors. These results suggested that CCL22 may be a biomarker and potential drug target in early OA. These results also suggested that CCL22 may be associated with OA pain, yet this was not examined directly and an in vivo model where CCL22 expression could be regulated would be required to test this hypothesis. While it was observed that CCL22 is expressed in damaged cartilage and acts on human chondrocytes and synovial fibroblasts, additional studies are required to determine how CCL22 triggered these changes in synovial fibroblasts as these results suggest this is CCR4 independent. Furthermore, it would be essential to validate these findings in an independent cohort to examine the sensitivity and/or specificity of CCL22 as an early OA biomarker.

description: Since the Russo-Georgian War of August 2008, the United States and the European Union has adamantly, and justifiably, refused to accept Russia’s post-war recognition of the declared independence of Abkhazia and South Ossetia. However, Washington and Brussels have failed, together and separately, to develop a realistic strategy toward the breakaway territories that takes changed political dynamics into account. Indeed, we do not have a workable policy at all; we have platitudes stuck in amber that ignore reality. The core realities we must acknowledge are, first, that these territories are almost certainly lost to Georgia, possibly for decades, and second, that Russian influence in both places has in- creased rapidly and substantially. Unless the United States changes its approach, the Russian Federation will soon completely absorb Abkhazia and South Ossetia. To prevent that outcome, we, together with the European Union, need urgently to end the current policy of isolation with respect to these territories and replace it with one of “engagement without recognition.”
The Stability of Visbroken Heavy Oil Against Asphaltene Precipitation

Subjects: subject: visbroken samples

subject: Engineering--Petroleum

description: Visbreaking is used in refinery and oilfield upgrading to reduce the viscosity of heavy oil (including bitumen) and residue feedstocks. However, if carried too far, this process can cause asphaltene precipitation and coke formation. A model that is able to predict the conditions at which the asphaltenes start to precipitate is required to design and optimize these thermal cracking processes. The Modified Regular Solution (MRS) approach has been widely used to model asphaltene precipitation from native and live oils (Tharanivasan, 2012, Akbarzadeh et al., 2005, and Akbarzadeh et al., 2005) and preliminary property correlations have been developed for solubility fractions from reacted oils (Yarranton et al., 2018, Powers et al., 2016). The goal of this thesis is to complete these correlations and apply the MRS model to asphaltene precipitation from visbroken heavy oils. An Athabasca bitumen was thermally cracked in a visbreaker pilot plant at five different temperatures and residence times. The thermal conversion for each visbroken product was calculated based on SimDist data. The feed and each product were characterized into 5 pseudo-components (distillates, saturates, aromatics, resins, and asphaltenes) using distillation and SARA assays. Properties required for the model input (molecular weight, density, and solubility parameters) were measured or estimated for each pseudo-component. New correlations were proposed for the distillate fractions as a function of conversion and the existing correlations for the SARA fractions were updated. The model inputs are then the feedstock composition, the feedstock pseudo-component properties, and conversion. The RSM model was able to match the measured asphaltene precipitation yields from visbroken heavy residues and visbroken whole oils with average absolute deviations of 1.2 wt% and 0.4 wt%, respectively. At this point, the model is valid for Western Canadian heavy oils derived from the same source oil as the sample used for this thesis.

description: We put forth the notion of efficient dual receiver cryptosystems and implement it based on bilinear pairings over certain elliptic curve groups. The cryptosystem is simple and efficient yet powerful, as it helps to solve two problems of practical importance whose solutions had proven to be elusive until now: (1) A provably secure "combined" public-key cryptosystem (with a single secret key per user) where the key is used for both decryption and signing and where encryption can be escrowed and recovered, while the signature capability never leaves its owner. This is an open problem proposed by the work of Haber and Pinkas. (2) A puzzle is a method for rate-limiting remote users by forcing them to solve a computational task (the puzzle). Puzzles have been based on cryptographic challenges in the past, but the successful design of embedding a useful cryptographic task inside a puzzle, originally posed by Dwork and Naor, has remained problematic. We model and present "useful security puzzles" applicable as an online transaction server (such as a Web server).

description: In the pursuit of sustainable lubricant materials, the conversion of common organic molecules into graphitic material has been recently shown to effectively reduce friction of metallic interfaces. Aromatic molecules are perfect candidates due to their inertness and possibility to form carbon-based tribofilms. Among many promising possibilities, we selected a group of common aromatic compounds and we investigated their capability to reduce the adhesion of iron interface. Ab initio molecular dynamic simulations of the sliding interface show that hypericin, a component of St. John's wort, effectively separates the mating iron surfaces better than graphene. This phenomenon is due to the size of the molecule, the reactivity of the moieties at its edges and the possibility to stack several of these structures that can easily slide on top of each other. The decomposition of the lateral groups of hypericin observed in the dynamic simulations suggests that the clustering of several molecules is possible, offering innovative paths to lubricate sliding contacts with compounds not typically employed in tribology.

description: Obama cannot recreate the 2008 campaign because he is now the incumbent, but he should not run from it entirely. Bringing out a strong African American vote and running as the optimistic forward looking candidate worked in 2008 and can play a key role in 2012 as well. If he does these things, and portrays his opponent as linked to the radical right that has taken over much of the Republican Party, Obama may be able to get reelected despite the economy.
Examining cortical involvement in the StartReact effect using transcranial magnetic stimulation
Creators: name: Stevenson, Andrew James
Publisher: name: University of British Columbia
Year: 2011

description: The goal of this thesis was to examine the subcortical storage and triggering hypothesis proposed by Valls-Solé et al. (1999) and Carlsen et al. (2004b). This hypothesis suggests movements that can be prepared in advance of an imperative stimulus are stored and triggered from subcortical areas without cortical involvement by a startling acoustic stimulus (SAS). The rapid release of prepared movements by a SAS has been termed the StartReact effect, and premotor reaction times (PMTs) <70 ms are often observed. We used transcranial magnetic stimulation (TMS) to probe cortical involvement in the StartReact effect. In Experiment 1 we examined whether a TMS-induced cortical silent period could delay the release of movement by a SAS. Thirteen participants performed 20° wrist extension movements as fast as possible in response to either a control tone (82.3 dB) or a SAS (123.2 dB). During selected control and startle trials, suprathreshold TMS was delivered to the contralateral primary motor cortex (M1) 50 or 70 ms prior to mean PMT. Startle PMTs were faster than control PMTs, while TMS significantly delayed movement onset in control and startle trials compared to No TMS or Sham TMS conditions. Additionally, TMS facilitated the size of the first agonist burst (AG1) in both control and startle trials. Experiment 1 provided evidence for the involvement of M1 in the StartReact effect, however, it was possible that suprathreshold TMS disrupted subcortical startle reflex pathways. Experiment 2 utilized subthreshold TMS to M1, which has been shown to reduce ongoing EMG activity during a voluntary contraction by activating inhibitory cortical interneurons and not descending motor pathways (Davey, et al., 1994). TMS was delivered to the contralateral M1 during AG1 activity in random control and startle trials. Despite all seven participants displaying TMS-induced suppression in isometric wrist extension, EMG suppression was observed in only one participant in control and startle trials. Data are discussed with respect to a recent model of preparation and initiation proposed by Carlsen et al. (in press).

description: Diamond-based coatings are employed in several technological applications, for their outstanding mechanical properties, biocompatibility, and chemical stability. Of significant relevance is the interface with silicon oxide, where phenomena of adhesion, friction, and wear can affect drastically the performance of the coating. Here we monitor such phenomena in real-time by performing massive ab initio molecular dynamics simulations in tribological conditions. We take into account many relevant factors that can play a role, i.e. the diamond surface orientation and reconstruction, silanol density, as well as, the type and concentration of passivating species. The large systems size and the long simulations time, put our work at the frontier of what can be currently done with fully ab initio molecular dynamics. The results of our work point to full hydrogenation as an effective way to reduce both friction and wear for all diamond surfaces, while graphitization is competitive only on the (111) surface. Overall we expect that our observations will be useful to improve technological applications where the silica-diamond interface plays a key role. Moreover, we demonstrate that realistic and accurate in silico experiments are feasible nowadays exploiting HPC resources and HPC optimized software, paving the way to a more general understanding of the relationship between surface chemistry and nanoscale-tribology.

description: Graph dynamic random walks (GDRWs) have recently emerged as a powerful paradigm for graph analytics and learning applications, including graph embedding and graph neural networks. Despite the fact that many existing studies optimize the performance of GDRWs on multi-core CPUs, massive random memory accesses and costly synchronizations cause severe resource underutilization, and the processing of GDRWs is usually the key performance bottleneck in many graph applications. This paper studies an alternative architecture, FPGA, to address these issues in GDRWs, as FPGA has the ability of hardware customization so that we are able to explore fine-grained pipeline execution and specialized memory access optimizations. Specifically, we propose LightRW, a novel FPGA-based accelerator for GDRWs. LightRW embraces a series of optimizations to enable fine-grained pipeline execution on the chip and to exploit the massive parallelism of FPGA while significantly reducing memory accesses. As current commonly used sampling methods in GDRWs do not efficiently support fine-grained pipeline execution, we develop a parallelized reservoir sampling method to sample multiple vertices per cycle for efficient pipeline execution. To address the random memory access issues, we propose a degree-aware configurable caching method that buffers hot vertices on-chip to alleviate random memory accesses and a dynamic burst access engine that efficiently retrieves neighbors. Experimental results show that our optimization techniques are able to improve the performance of GDRWs on FPGA significantly. Moreover, LightRW delivers up to 9.55x and 9.10x speedup over the state-of-the-art CPU-based MetaPath and Node2vec random walks, respectively.

description: Short period planets are subject to intense energetic irradiations from their stars. It has been shown that this can lead to significant atmospheric mass-loss and create smaller mass planets. Here, we analyse whether the evaporation mechanism can affect the orbit of planets. The orbital evolution of a planet undergoing evaporation is derived analytically in a very general way. Analytical results are then compared with the period distribution of two classes of inner exoplanets: Jupiter-mass planets and Neptune-mass planets. These two populations have a very distinct period distribution, with a probability lower than 10^-4 that they were derived from the same parent distribution. We show that mass ejection can generate significant migration with an increase of orbital period that matches very well the difference of distribution of the two populations. This would happen if the evaporation emanates from above the hottest region of planet surface. Thus, migration induced by evaporation is an important mechanism that cannot be neglected.

description: This paper describes a novel underactuated robotic hand design. The hand is highly underactuated as it contains three fingers with three joints each controlled by a single motor. One of the fingers ("thumb") can also be rotated about the base of the hand, yielding a total of two controllable degrees-of-freedom. A key component of the design is the addition of position and tactile sensors which provide precise angle feedback and binary force feedback. Our mechanical design can be analyzed theoretically to predict contact forces as well as hand position given a particular object shape.

description: In this Letter, we report Very Long Baseline Array observations of 22 GHz water masers toward the protostar CARMA-6, located at the center of the Serpens South young cluster. From the astrometric fits to maser spots, we derive a distance of 440.7+/-3.5 pc for the protostar (1% error). This represents the best direct distance determination obtained so far for an object this young and deeply embedded in this highly obscured region. Taking into account depth effects, we obtain a distance to the cluster of 440.7+/-4.6 pc. Stars visible in the optical that have astrometric solutions in the Gaia Data Release 3 are, on the other hand, all located in the periphery of the cluster. Their mean distance of 437 (+51, -41) pc is consistent within 1-sigma with the value derived from maser astrometry. As the maser source is just at the center of Serpens South, we finally solve the ambiguity of the distance to this region that has prevailed over the years.

description: Heavy oil resources provide a significant percentage of total Canadian carbon energy production. They can be produced using enhanced oil recovery (EOR) processes. The capacity of polymer gel as a blocking agent applied in a heavy oil field to recover oil, however, still remains unclear. A numerical simulation approach is used to investigate the connection and difference between secondary and tertiary recovery techniques to provide a better understanding of the polymer gel EOR process. The performance and key mechanism of a gel treatment applied in a heavy oil field is simulated for the first time by a novel reservoir simulation model in this study. A newly-introduced economic evaluation model built for the project proves the value of using a polymer gel and can be used as a simple method to evaluate other projects using polymer gel EOR techniques.

description: Combing horizontal wells with hydraulic fracturing is a powerful technology used to stimulate unconventional tight reservoirs and has increased production performance of tight oil reservoirs. The analysis of optimal hydraulic fracture patterns, the effects of their properties and the controlling factors affecting oil production all need to be studied to advance tight oil recovery. This thesis uses reservoir simulation models for a Jilin tight oil reservoir in China. The relationship between the variables of a rate decline prediction formula and the fracture geometry parameters are analyzed. The outcomes can be used to forecast future production performance based on known information gained about the existing fracture patterns in tight oil reservoir. Impacts of hydraulic fracture patterns and fracture closure on production performance of this tight oil reservoir are studied. A sensitive study is performed to identify the most influential factors and the optimal properties for hydraulic fracturing in the Jilin field.

description: We revisit the Perelomov SU(1,1) displaced coherent states states as possible quantum states of light. We disclose interesting statistical aspects of these states in relation with photon counting and squeezing. In the non-displaced case we discuss the efficiency of the photodetector as inversely proportional to the parameter k of the discrete series of unitary irreducible representations of SU(1,1). In the displaced case, we study the counting and squeezing properties of the states in terms of k and the number of photons in the original displaced state. We finally examine the quantization of a classical radiation field which is based on these families of coherent states. The procedure yields displacement operators which might allow to prepare such states in the way proposed by Glauber for the standard coherent states.

Evolutionary optimization of optical antennas

description: The design of nano-antennas is so far mainly inspired by radio-frequency technology. However, material properties and experimental settings need to be reconsidered at optical frequencies, which entails the need for alternative optimal antenna designs. Here a checkerboard-type, initially random array of gold cubes is subjected to evolutionary optimization. To illustrate the power of the approach we demonstrate that by optimizing the near-field intensity enhancement the evolutionary algorithm finds a new antenna geometry, essentially a split-ring/two-wire antenna hybrid which surpasses by far the performance of a conventional gap antenna by shifting the n=1 split-ring resonance into the optical regime.

description: While web-based communications (e.g., webmail or web chatrooms) are increasingly protected by transport-layer cryptographic mechanisms, such as the SSL/TLS protocol, there are many situations where even the web server (or its operator) cannot be trusted. The end-to-end (E2E) encryption of data becomes increasingly important in these trust models to protect the confidentiality and integrity of the data against snooping and modification. We introduce W3Bcrypt, an extension to the Mozilla Firefox platform that enables application-level cryptographic protection for web content. In effect, we view cryptographic operations as a type of style to be applied to web content, similar to and along with layout and coloring operations. Among the main benefits of using encryption as a stylesheet are (a) reduced workload on the web server, (b) targeted content publication, and (c) greatly increased privacy. This paper discusses our implementation for Firefox, although the core ideas are applicable to most current browsers.
Vascular Smooth Muscle Cell Development in Zebrafish

description: During the formation of blood vessels, the endothelium becomes progressively covered by vascular smooth muscle cells and pericytes, known collectively as vascular mural cells. The vascular mural cells of the head arise from migratory neural crest and lateral mesodermal populations, and differentiate into mural cells which surround the endothelium of blood vessels, providing support and contraction. Using zebrafish as a model, we created transgenic reporter lines for acta2/αsma (α-smooth muscle actin) that label mature vascular and visceral smooth muscle. Using these reporters, we study the cellular dynamics of mature vascular smooth cells along the ventral aorta and in the brain. These reporter lines only begin robust expression of vascular mural cells at 4 days post fertilization (dpf); however, there are peri-vascular cells present around the endothelium by 2 dpf. Therefore, there is a need to identify an earlier marker of the vascular mural cell lineage. One such marker is the forkhead box transcription factor foxc1b. Utilizing a foxc1b:EGFP reporter line, foxc1b labels groups of mesenchymal cells which undergo a morphological change to associate with the endothelium, and then later co-express the mature smooth muscle marker acta2. These vascular smooth muscle cells on the ventral aorta are the earliest identified smooth muscle cells in the zebrafish embryo. foxc1b:EGFP continues to label smooth muscle cells through the lifespan of zebrafish, but is not co-expressed with pdgfrβ (platelet derived growth factor β) and therefore likely does not label pericytes. Thus, foxc1b is an early smooth muscle marker, but not a pericyte marker. To assess if there are transcriptomic differences between mural cell populations, fluorescence-activated cell sorting and RNA Sequencing were used to identify differentially expressed genes. Further examination of genes from the RNA Sequencing datasets reveals novel vascular mural cell markers. One highly differentially expressed gene was Ras-like family protein member 12, rasl12. rasl12 is expressed in both smooth muscle cells and pericytes. rasl12 knockout mutants were created, but there were large phenotypic differences between two mutant alleles, requiring further study. Overall, this thesis addresses the development of vascular smooth muscle cells, by labelling and visualizing cellular behaviors in zebrafish.
Computing A-Homotopy Groups of Graphs Using Coverings and Lifting Properties

description: In classical homotopy theory, two spaces are homotopy equivalent if one space can be continuously deformed into the other. This theory, however, does not respect the discrete nature of graphs. For this reason, a discrete homotopy theory that recognizes the difference between the vertices and edges of a graph was invented, called A-homotopy theory. In classical homotopy theory, covering spaces and lifting properties are often used to compute the fundamental group of a space. In this thesis, we develop the lifting properties for A-homotopy theory. Using a covering graph and these lifting properties, we compute the fundamental group of the cycle C_5 and use this computation to show that C_5 is not contractible in this theory, even though the cycles C_3 and C_4 are contractible.

description: The sunspot drawings of Johann Staudacher of 1749--1799 were used to determine the solar differential rotation in that period. These drawings of the full disk lack any indication of their orientation. We used a Bayesian estimator to obtain the position angles of the drawings, the corresponding heliographic spot positions, a time offset between the drawings and the differential rotation parameter δΩ, assuming the equatorial rotation period is the same as today. The drawings are grouped in pairs, and the resulting marginal distributions for δΩwere multiplied. We obtain δΩ=-0.048 \pm 0.025 d^-1 (-2.75^o/d) for the entire period. There is no significant difference to the value of the present Sun. We find an (insignificant) indication for a change of δΩthroughout the observing period from strong differential rotation, δΩ\approx -0.07 d^-1, to weaker differential rotation, δΩ\approx-0.04 d^-1.
