Arthrodesis
Charcot arthropathy
Knee
Total knee arthroplasty

description: Abstract: Background: Charcot arthropathy is a progressive, non-infectious, destructive inflammatory process. Charcot arthropathy of the knee (CK) is rare and diagnosis is often delayed, resulting in detrimental outcomes. This scoping review aims to investigate the literature on CK, present the pathognomonic features of CK to aid early diagnosis, and suggest gaps in the literature for future research. Methods: A systematic search of PubMed, EMBASE, Web of Science for literature relevant to CK was performed. Primary studies such as case reports, case series, retrospective studies were included. Review articles and animal studies were excluded. Results: Of the 513 results, 58 were included in qualitative synthesis. Average time from symptom onset to CK diagnosis was 50.5 months. Eighteen and twenty-one studies included patients who had diabetes mellitus and syphilis, respectively. Twenty-one studies reported pain as a presenting complaint, but the degree of pain didn’t correspond with the level of destruction. Oedema and joint effusion were noticed in 34 studies. Twenty-nine studies reported lower limb hypoesthesia and 17 studies reported decreased tendon reflex. Twenty-eight studies reported initial conservative treatment, often in a knee brace with minimal weight bearing, 9 of which needed subsequent surgical management. Twelve studies utilised arthrodesis, with fracture at the intramedullary nail entry site being the most common complication. Twenty-four studies utilised TKA. Conclusion: The literature on CK remains sparse, with most publications being case reports. Given that CK dramatically reduces quality of life, increases morbidity of patients, there is need for more literature on evidence-based options for early diagnoses and management.

description: The Mg II k resonance line is commonly used for diagnosing the solar chromosphere. We theoretically investigated its intensity and polarization in solar prominences, taking 3D radiative transfer and Hanle and Zeeman effects into account. We used an optically thick 3D model representative of a solar prominence and applied several inversion methods to the synthetic Stokes profiles, clarifying their pros and cons for inferring prominence magnetic fields. We conclude that the self-consistent 3D inversion with radiative transfer is necessary to determine the magnetic field vector, although its geometry cannot be inferred with full fidelity. We also demonstrate that more traditional methods, such as those based on the weak field approximation or the constant-property slab assumption, can offer useful information under certain conditions.

description: Abstract: Neuromodulation is a new therapeutic pathway to treat inflammatory conditions by modulating the electrical signalling pattern of the autonomic connections to the spleen. However, targeting this sub-division of the nervous system presents specific challenges in translating nerve stimulation parameters. Firstly, autonomic nerves are typically embedded non-uniformly among visceral and connective tissues with complex interfacing requirements. Secondly, these nerves contain axons with populations of varying phenotypes leading to complexities for axon engagement and activation. Thirdly, clinical translational of methodologies attained using preclinical animal models are limited due to heterogeneity of the intra- and inter-species comparative anatomy and physiology. Here we demonstrate how this can be accomplished by the use of in silico modelling of target anatomy, and validation of these estimations through ex vivo human tissue electrophysiology studies. Neuroelectrical models are developed to address the challenges in translation of parameters, which provides strong input criteria for device design and dose selection prior to a first-in-human trial.

description: (Abridged) Observational surveys of entire star-forming regions have provided evidence of power-law correlations between the disc properties and the stellar mass, especially the disc mass (${M_d \propto M_*}^{λ_m}$) and the accretion rate ($\dot M \propto {M_*}^{λ_{acc}}$). Whether the secular disc evolution affects said correlations is still debated: while the purely viscous scenario has been probed, other mechanisms could impact differently. We study the evolution of the slopes $λ_m$ and $λ_{acc}$ in the wind-driven and hybrid case and compare it to the viscous prediction, using a combination of analytical calculations and numerical simulations (performed with the 1D population synthesis code Diskpop, that we also present and release). Assuming $M_d(0) \propto {M_*}^{λ_{m, 0}}$ and $\dot M(0) \propto {M_*}^{λ_{acc, 0}}$ as initial conditions, we find that viscous and hybrid accretion preserve the shape of the correlations and evolve their slope; on the other hand, MHD winds change the shape of the correlations, bending them according to the scaling of the accretion timescale with the stellar mass. We also show how a spread in the initial conditions conceals this behaviour. We then analyse the impact of disc dispersal, and find that the currently available sample sizes ($\sim 30$ discs at 5 Myr) introduce stochastic oscillations in the slopes evolution, which dominate over the physical signatures. Increasing the sample size could mitigate this issue: $\sim 140$ discs at 5 Myr, corresponding to the complete Upper Sco sample, would give small enough error bars to use the evolution of the slopes as a proxy for the driving mechanism of disc evolution. Finally, we discuss how the observational claim of steepening slopes necessarily leads to an initially steeper $M_d - M_*$ correlation with respect to $\dot M - M_*$.

description: Cobalt oxide (Co3O4)-based nanostructures have the potential as low-cost materials for lithium-ion (Li-ion) and sodium-ion (Na-ion) battery anodes with a theoretical capacity of 890 mAh/g. Here, we demonstrate a novel method for the production of Co3O4 nanoplatelets. This involves the growth of flower-like cobalt oxyhydroxide (CoOOH) nanostructures at a polarized liquid|liquid interface, followed by conversion to flower-like Co3O4 via calcination. Finally, sonication is used to break up the flower-like Co3O4 nanostructures into two-dimensional (2D) nanoplatelets with lateral sizes of 20−100 nm. Nanoplatelets of Co3O4 can be easily mixed with carbon nanotubes to create nanocomposite anodes, which can be used for Li-ion and Na-ion battery anodes without any additional binder or conductive additive. The resultant electrodes display impressive low-rate capacities (at 125 mA/g) of 1108 and 1083 mAh/g, for Li-ion and Na-ion anodes, respectively, and stable cycling ability over >200 cycles. Detailed quantitative rate analysis clearly shows that Li-ion-storing anodes charge roughly five times faster than Na-ion-storing anodes
The alkaline pressure oxidation of gold-containing pyrite as a pretreatment prior to gold leaching : fundamentals and new approaches
Creators: name: Song, Chulho
Publisher: name: University of British Columbia
Year: 2022

description: Due to the depletion of gold ore easily processed, the demand for processing high carbonate refractory gold ore is increasing worldwide, and accordingly, the interest in alkaline pressure oxidation (POX) is also increasing. This study was conducted with the aim of investigating the fundamental kinetics of alkaline pressure oxidation and testing new concepts to improve the pre-existing alkaline POX process. Magnesium carbonate (MgCO₃) was proposed as an alternative alkaline reagent instead of sodium carbonate (Na₂CO₃). Formation of kieserite (MgSO₄·H₂O) at high temperatures has been confirmed. Addition of MgCO₃ may have a positive effect on cyanidation by replacing a part of the iron oxide - calcium sulfate based product layer with kieserite, which is expected to re-dissolve at low temperature and leave pores in the oxidized solid. However, the direct addition of MgCO₃ showed limitations in terms of extent of sulfide oxidation and gold recovery. A further attempt was made to affect the POX chemistry by addition of magnesium sulfate as a pre-treatment. This method showed potential regarding reduction of calcium carbonate (CaCO₃) reactivity as well as formation of desired magnesium hydroxide precipitate in the MgSO₄ pre-treatment stage. Two stage tests (MgSO₄ pre-treatment followed by alkaline POX) verified that the magnesium sulfate addition to POX had a beneficial effect on the gold recovery (8-10% increased) with a concurrent increase of sulfide oxidation. The kinetic study of pyrite oxidation showed the reaction rate can be modelled with the shrinking core model (SCM), and pyrite oxidation is under chemical reaction control in the initial stage regardless of key parameters (particle size, temperature, and Po2). However, rate control mechanism shifts to product layer diffusion with the effect of build-up of product layer. The activation energy for pyrite oxidation in the starting period was calculated at 36.1 kJ/mol which implied the reaction is controlled by chemical reaction, whereas the activation energy with a longer time span dramatically decreases to 15.9 kJ/mol (thought to be due to product layer diffusion rate control). In addition, it was found that excessive Na₂CO₃ addition to the POX system could have a detrimental effect on pyrite oxidation.

description: We present the first comprehensive analysis of the argon K-edge absorption region (3.1-4.2 Å) using high-resolution HETGS {\it Chandra} spectra of 33 low-mas X-ray binaries. Utilizing R-matrix theory, we computed new K photoabsorption cross-sections for {\rm Ar}~{\sc i}--{\rm Ar}~{\sc xvi} species. For each X-ray source, we estimated column densities for the {\rm Ar}~{\sc i}, {\rm Ar}~{\sc ii}, {\rm Ar}~{\sc iii}, {\rm Ar}~{\sc xvi}, {\rm Ar}~{\sc xvii} and {\rm Ar}~{\sc xviii} ions, which trace the neutral, warm and hot components of the gaseous Galactic interstellar medium. We examined their distribution as a function of Galactic latitude, longitude, and distances to the sources. However, no significant correlations were discerned among distances, Galactic latitude, or longitude. Future X-ray observatories will allow us to benchmark the atomic data as the main resonance lines will be resolved.

Enhancing the characterization of forest structure and resources for forest inventory and monitoring using airborne and spaceborne single photon lidar
Creators: name: Queinnec, Martin
Publisher: name: University of British Columbia
Year: 2022

description: Canada’s forests cover about 347 million ha, of which 157 million ha are actively managed for timber procurement and 114 million ha are located in northern remote areas and mostly unmanaged. Information about forest resources is needed to inform sustainable forest management practices and monitor the evolution of forested ecosystems, particularly in the context of climate change. In the past decades, airborne acquisitions of light detection and ranging (lidar) data have been increasingly used to map forest structure. However, their acquisitions remain expensive and coverage is often limited to targeted managed forest units. Recent technological advances led to the development of single photon lidar (SPL) systems that enable high-altitude airborne and spaceborne lidar acquisitions with an unprecedented amount of detail and across large geographic extents. Two SPL systems are currently available: the airborne SPL100 instrument, commercially released in 2017, and the spaceborne Advanced Topographic Laser Altimeter System (ATLAS) onboard the Ice Cloud and Elevation Satellite-2 (ICESat-2) launched in September 2018. However, the ability of these two systems to accurately characterize forest structure and resources is not well defined. The primary objective of this dissertation is to examine the role that SPL100 and ICESat-2 can play to provide spatially-explicit, timely and accurate estimates of some key information needs in managed and unmanaged boreal forests of Canada. To that end, an enhanced inventory of key forest attributes driven by SPL100 data was implemented across an actively managed boreal forest located in Ontario, Canada. Strengths and limitations of ICESat-2 metrics to accurately characterize canopy height, cover and vertical vegetation structure were also highlighted by comparing them to SPL100 counterparts. Moving on to a broader monitoring perspective, a method to extrapolate ICESat-2 samples of canopy height estimates across over 19 million ha of unmanaged boreal forests was implemented. Time-series of this wall-to-wall product were also produced and used to examine the recovery of vegetation height after disturbance. The research presented in this dissertation helps better understanding the ability of SPL100 and ICESat-2 to characterize vegetation structure in both managed and unmanaged forests in order to inform policy-making and sustainable forest management practices.

description: Sulphur-bearing species play crucial roles in interstellar chemistry, yet their precise characterisation remains challenging. Here, we present laboratory experiments aimed at extending the high-resolution spectroscopy of protonated carbonyl sulphide (HOCS$^+$), a recently detected molecular ion in space. Using a frequency-modulated free-space absorption spectrometer, we detected rotational transitions of HOCS$^+$ in an extended negative glow discharge with a mixture of H$_2$ and OCS, extending the high-resolution rotational characterisation of the cation well into the millimetre wave region (200-370 GHz). Comparisons with prior measurements and quantum chemical calculations revealed an overall agreement in the spectroscopic parameters. With the new spectroscopic dataset in hand, we re-investigated the observations of HOCS$^+$ towards G+0.693-0.027, which were initially based solely on K$_a$ = 0 lines contaminated by HNC$^{34}$S. This re-investigation enabled the detection of weak K$_a$ = 0 transitions, free from HNC$^{34}$S contamination. Our high-resolution spectroscopic characterisation also provides valuable insights for future millimetre and submillimetre astronomical observations of these species in different interstellar environments. In particular, the new high-resolution catalogue will facilitate the search for this cation in cold dark clouds, where very narrow line widths are typically observed.

description: Discovering mixed state quantum orders is an on-going issue. Recently, it has been recognized that there are (at least) two kinds of symmetries in the mixed state; strong and weak symmetries. Under symmetry-respective decoherence, spontaneous strong-to-weak symmetry breaking (SSSB) can occur. This work provides a scheme to describe SSSB and other decoherence phenomena in the mixed state by employing the stabilizer formalism and the efficient numerical algorithm of Clifford circuits. We present two systematic numerical studies.In a two-dimensional (2D) circuit with a stochastic Ising type decoherence, an SSSB phase transition is clearly observed and its criticality is elucidated by the numerical methods. In particular, we calculate Rényi-2 correlations and estimate critical exponents of the SSSB transition. For the second system, we introduce an idea of subgroup SSSB. As an example, we study a system with symmetry-protected-topological (SPT) order provided by both one-form and zero-form symmetries, and observe how the system evolves under decoherence. After displaying numerical results, we show that viewpoint of percolation is quite useful to understand the SSSB transition, which is applicable for a wide range of decohered states. Finally, we comment on SSSB of one-form-symmetry exemplifying toric code.

description: Το μαγγάνιο είναι ένα από τα δέκα πιο διαδεδομένα στοιχεία στο φλοιό της Γης και έχει συγκεντρώσεις συνήθως υψηλότερες από 0.1 wt% στο μέσο ηπειρωτικό φλοιό. Τα κοιτάσματα μαγγανίου διακρίνονται σε πρωτογενή που συνδέονται άμεσα ή έμμεσα με υδροθερμική δραστηριότητα μεσοωκεάνιας ράχης, είτε δευτερογενή ελεγχόμενα από εξωγενείς, αποθετικές και μεταμορφικές γεωλογικές διεργασίες. Στο Ελληνικό Ορογενές ενώ υπάρχουν πολλές δεκάδες εμφανίσεις μαγγανίου διαφόρων τύπων δεν υπάρχουν μεγάλα κοιτάσματα μαγγανίου. Αυτά πολύ έτυχαν συστηματικής εκμετάλλευσης ήταν τα κοιτάσματα κυρίως στην Βόρειο Ελλάδα. Η εκμετάλλευση μαγγανιούχων κοιτασμάτων στην Ελλάδα διακόπηκε στα μέσα της δεκαετίας του ΄90, αν και είναι η μοναδική χώρα στην ΕΕ που διαθέτει αποθέματα αυτού του μετάλλου. Στην Κρήτη έχουν καταγραφεί δύο μικρών διαστάσεων εμφανίσεις μαγγανίου στα Λευκά Όρη. Το μοναδικό κοίτασμα μαγγανίου του έτυχε εκμετάλλευσης τις προηγούμενες δεκαετίες στην Κρήτη  βρίσκεται στην ευρύτερη περιοχή του χωριού Άνω Μέρος της επαρχίας Αμαρίου του νομού Ρεθύμνης.
Σκοπός αυτής της διπλωματικής εργασίας αυτής είναι αρχικά η καταγραφή της σχετικά άγνωστης αυτής μεταλλευτικής δραστηριότητας στην Κρήτη. Επιπρόσθετα ο ορυκτολογικός και γεωχημικός προσδιορισμός του μεταλλεύματος που εξορύχτηκε και τελικός σκοπός, η μελέτη της κατανομής των κύριων στοιχείων και  ιχνοστοιχείων, με έμφαση την κατανομή του χρυσού εντός αυτών. Με βάση τα αποτελέσματα των γεωχημικών και ορυκτολογικών αναλύσεων σε μεταλλευτικά υπολείμματα της περιοχής μελέτης φάνηκε η έντονη παρουσία του μαγγανιούχου ορυκτού μπραουνίτη (Mn2+Mn3+6[O8|SiO4]) ο οποίος συνοδεύεται από χαλαζία (SiO2). Επίσης εντός των δειγμάτων μαγγανιούχου μεταλλεύματος ανιχνεύθηκαν θείο (S), αρσενικό (As) και το στρόντιο (Sr) σε αρκετά υψηλές συγκεντρώσεις. Η συγκέντρωση του θείου  κυμαίνεται από 1633 ppm-6126 ppm. Η συγκέντρωση του αρσενικού κυμαίνεται από 134,4 ppm- 241,5 ppm εκτός των δειγμάτων L6 και L9 που έχουν συγκέντρωση 58,8ppm και 96,6 ppm αντίστοιχα. Επιπλέον η συγκέντρωση στροντίου(Sr) είναι αρκετά υψηλή και κυμαίνεται από 344,4ppm-1107ppm ενώ χαμηλότερες συγκεντρώσεις παρατηρούνται σε ιχνοστοιχεία όπως ο χαλκός (Cu) με τιμές που φθάνουν έως και 81,3ppm, ο ψευδάργυρος (Ζn) με τιμές που φθάνουν έως 69,8ppm και το νικέλιο (Ni) με τιμές που φθάνουν έως 39,9ppm εκτός του δείγματος L8 που έχει συγκέντρωση 121,1ppm. Τέλος σε τέσσερα δείγματα ξεκινώντας με την μέθοδο της πυρανάλυσης (Fire assay) - δοκιμές κυπέλλωσης μετρήθηκαν οι περιεκτικότητες χρυσού Au οι οποίες κινήθηκαν σε μικρές τιμές από 34-41 ppb, καθιστώντας τα μεταλλευτικά υπόλειμμα του εξαντλημένου μαγγανιούχου κοιτάσματος στην θέση Ρημάμπελο του Άνω Μέρους μια θέση γεωλογικού, αλλά όχι κοιτασματολογικού ενδιαφέροντος.

description: Current research in food analysis primarily concentrates on tasks such as food recognition, recipe retrieval and nutrition estimation from a single image. Nevertheless, there is a significant gap in exploring the impact of food intake on physiological indicators (e.g., weight) over time. This paper addresses this gap by introducing the DietDiary dataset, which encompasses daily dietary diaries and corresponding weight measurements of real users. Furthermore, we propose a novel task of weight prediction with a dietary diary that aims to leverage historical food intake and weight to predict future weights. To tackle this task, we propose a model-agnostic time series forecasting framework. Specifically, we introduce a Unified Meal Representation Learning (UMRL) module to extract representations for each meal. Additionally, we design a diet-aware loss function to associate food intake with weight variations. By conducting experiments on the DietDiary dataset with two state-of-the-art time series forecasting models, NLinear and iTransformer, we demonstrate that our proposed framework achieves superior performance compared to the original models. We make our dataset, code, and models publicly available at: https://yxg1005.github.io/weight-prediction/.

Identification of the deformylase ArnD involved in lipid A modification and the synthesis of isoprenoid biosynthetic pathway inhibitors
Creators: name: Adak, Taniya
Publisher: name: University of British Columbia
Year: 2022

description: Lipopolysaccharide is a major component of the outer membrane of Gram-negative bacteria and contains an immunogenic 𝘣𝘪𝘴-phosphorylated lipid A. Cationic antimicrobial peptides and polymyxins are electrostatically attracted to the lipid A and cause membrane rupture and bacterial cell death. Therefore, many strains of Gram-negative bacteria covalently attach positively charged groups on the phosphates to decrease overall surface charge and evade antibiotic action. One such modifying group is 4-amino-4-deoxy-L-arabinose (L-Ara4N) and the biosynthesis of L-Ara4N has been studied in this thesis. One of the enzymes in the biosynthetic pathway has been hypothesized to be the deformylase, ArnD. ArnD, catalyzes the deformylation of undecaprenyl 4-formamido-4-deoxy-L-arabinosyl -α-phosphate (L-Ara4FN) to produce undecaprenyl phosphate-α-L-Ara4N, the donor substrate required for the addition of L-Ara4N to lipid A. In this work, activity of ArnD was demonstrated for the first time. This was achieved by synthesizing substrate analogs and testing for ArnD catalyzed deformylation. ArnD was shown to be a metalloenzyme and attempts were made towards the biochemical and structural characterization of the deformylase. Through experimental observations, ArnD is speculated to be a membrane-associated enzyme that partially extracts its substrate from the inner leaflet of the inner membrane. Full characterization of ArnD will allow design and testing of inhibitors, thereby paving way for new antibiotic development. In another project, mechanism-based competitive inhibitors were designed and synthesized for a few representatives from prenyltransferase class of enzymes. The inhibition of these enzymes could be useful to treat diseases like cancer and hypercholesterolemia. Enzymes that utilize allylic iv diphosphates and generate intermediates/ transition states with considerable carbocationic character were targeted. The inhibitors mimicked the transition state for substrate dissociation utilizing a planar and positively charged amidinium moiety. Contrary to our hypothesis, the inhibitors showed modest inhibition and it was concluded that not all of these enzymes evolve to stabilize a carbocation. A better inhibition strategy utilizing amidiniums could focus on enzymes that are required to evolve stabilization forces for a carbocationic intermediate.

description: In situ, le béton concassé obtenu provenant des déchets de construction et de démolition est toujours mélangé avec d'autres matériaux concassés tels que l'asphalte, la brique, le gypse, le verre ... Dans la littérature, des jigs ont été proposés pour concentrer les particules de béton et / ou diminuer les impuretés d'un granulat recyclé mélangé à la suite d'un tri par densité. Les Granulats de béton recyclés (GBR) sont composés principalement de deux matériaux différents : le granulat naturel (gravillon ou sable) et la pâte de ciment attachée. Il est généralement admis que plus la taille des GBR est fine, plus la quantité de pâte de ciment collée est importante. Dans cette étude, l’hétérogénéité d’une classe granulaire étroite des GBR (6.3/10) a été étudiée en triant les échantillons en fonction de leur densité en utilisant un jig à eau de laboratoire. Il est montré que l'absorption d'eau moyenne après une immersion pendant 24 heures est d'environ 5% pour des échantillons extraits du lot de GBR avant les essais de tri. En revanche, pour les échantillons homogènes séparés par densité, le coefficient d’absorption d’eau varie entre 2% et 9%. L’absorption des GBR suit une distribution log-normale. Cette hétérogénéité intrinsèque implique la possibilité d'avoir des échantillons représentatifs avec une précision suffisante, non seulement en ce qui concerne la taille mais aussi la composition minérale des grains dans les stocks industriels de GBR. Le jig à eau semble donc être un outil efficace pour séparer les GBR par densité et obtenir des échantillons représentatifs reconstruits pour leur caractérisation.

Prospects of FRBs and Large Scale 21 cm Power Spectra in Constraining the Epoch of Reionization

description: The Epoch of Reionization (EoR) is a crucial link to grasp the complete evolutionary history of the universe. Several attempts with a variety of observables have been utilized in the past to understand the thermal and ionization evolution of the Intergalactic Medium during EoR. In this study, we explore the simultaneous prospects of two important observables which are expected to be available in the near future, i.e. Dispersion Measure (DM) of high redshift FRBs and large scale 21 cm power spectra. For this purpose, we use an earlier developed explicitly photon conserving semi numerical model, $\texttt{SCRIPT}$ including realistic recombination and radiative feedback effect. We check that DM evolution of 100 mock FRBs at high redshifts ($7.0\le z\le15.0$) is sufficient to recover the underlying reionization model, while 1000 FRB mocks at redshift range can constrain the reionization timeline within the percentage level uncertainties at 68\% confidence limit. Further, we study the effect of including large scale 21~cm power spectra (using only a single bin, $k\sim0.14~h/\mathrm{cMpc}$) at three redshifts along with FRB DM distribution. The joint exploration using these two observables can significantly improve the constraints on the various parameters ($\lesssim 8\%$ uncertainties for reionization interval and midpoint at 95\% confidence) alleviating the degeneracies and can narrow down the thermal history of the universe by discarding some of the extreme heating models.

Interaction- and phonon-induced topological phase transitions in double helical liquids

description: Helical liquids, formed by time-reversal pairs of interacting electrons in topological edge channels, provide a platform for stabilizing topological superconductivity upon introducing local and nonlocal pairings through the proximity effect. Here, we investigate the effects of electron-electron interactions and phonons on the topological superconductivity in two parallel channels of such helical liquids. Interactions between electrons in different channels tend to reduce nonlocal pairing, suppressing the topological regime. Additionally, electron-phonon coupling breaks the self duality in the electronic subsystem and renormalizes the pairing strengths. Notably, while earlier perturbative calculations suggested that longitudinal phonons have no effect on helical liquids themselves to the leading order, our nonperturbative analysis shows that phonons can induce transitions between topological and trivial superconductivity, thereby weakening the stability of topological zero modes. Our findings highlight practical limitations in realizing topological zero modes in various systems hosting helical channels, including quantum spin Hall insulators, higher-order topological insulators, and their fractional counterparts recently observed in twisted bilayer systems.

description: In relativistischen Schwerionenkollisionen entsteht ein neuer Materiezustand, das Quark-Gluon-Plasma. Eine Möglichkeit, dessen Eigenschaften zu untersuchen, sind Jets, in der Kollision entstandene hochenergetische Teilchen, die mit den Quarks und Gluonen wechselwirken und dann in einem Detektor gemessen werden können. Die transversale Impulsänderung eines solchen Teilchens kann mit dem jet quenching Parameter q̂ quantifiziert werden, für den ich in dieser Arbeit eine Formel aus der effektiven kinetischen Beschreibung des Plasmas herleite. In unserer Beschreibung kann der Jet hierbei beliebigen Impuls und Richtung relativ zur Strahlachse haben. Wenn man den Grenzwert des Impulses gegen unendlich betrachtet, muss man einen maximalen Impulsübetrag definieren, damit q̂ endlich bleibt. Dann beschreibe ich die Implementierung dieser Formeln in einem C++ Code, der die Zeitentwicklung eines gluonischen Plasmas simuliert. Die numerischen Resultate, die für isotrope Teilchenverteilungen erhalten werden, werden mit bekannten analytischen Berechnungen im thermischen Gleichgewicht und mit experimentellen Grenzwerten verglichen. Außerdem berechne ich q̂ für verschiedene skalierte thermische Verteilungen.
description: In relativistic heavy-ion collisions a new state of matter is created that is referred to as the Quark-Gluon Plasma (QGP). To probe its properties one can use jets, which are highly energetic particles that are formed in the collision and traverse the plasma, while interacting with quarks and gluons, and can then be measured in a detector. The rate of change of their transverse momentum squared is quantified by the jet quenching parameter q̂, for which, in this thesis, I derive a formula for the effective kinetic theory description of the plasma. In our framework the jet can have an arbitrary momentum and direction with respect to the beam axis. When considering the limit of the jet momentum going to infinity, we need to introduce a momentum cutoff in order to render q̂ finite. I then describe the implementation of the corresponding formulae in a C++ code that simulates the time-evolution of a gluonic plasma. The numerical results obtained for isotropic particle distributions are finally compared with previous analytic calculations in thermal equilibrium and with bounds from experimental observations. Moreover, I also compute q̂ for different scaled thermal distributions.

description: Surface mine reclamation has been an evolving practice since the Surface Mining Control and Reclamation Act was passed in 1977, holding mining companies accountable for returning ecological function to areas directly impacted by mining activities. One recent method of reclamation, the Forestry Reclamation Approach (FRA), aims to enhance reforestation and ecosystem function through the creation of wetlands, as opposed to traditional methods that often revert land to grasslands. However, wildlife response to FRA has rarely been investigated. The goal of this project was to analyze the effects of the four treatment types, FRA in two chronosequences, natural regeneration, and unmined mature forest, on amphibian occupancy, species richness and abundance. The results of this project show that FRA wetlands are able to support most pond-breeding amphibian species in the region. I found that species had similar occupancy and species richness estimates values across the four treatments. Abundance estimates were lower in young FRA sites for forest-associated species, such as L. sylvaticus and A. maculatum, but higher abundance estimates in older FRA sites suggest that these species will be able to successfully utilize these wetlands in the near future.

title: Ixodes Scapularis SRC Kinase Is Required for Rickettsial Pathogen Survival in Ticks

Publisher: name: Old Dominion University Libraries

description: Anaplasma phagocytophilum is an obligate intracellular bacterium that causes disease in humans and animals. It is the causative agent for human anaplasmosis. A. phagocytophilum uses certain strategies to infect both vertebrates and invertebrates. It uses Ixodes scapularis ticks as a vector for spreading infection to other mammal species. This bacterium has a specific path for infection through the salivary glands of its vector host. It also suppresses certain functions such as the inhibition of apoptosis and ROS production in order to increase its survival in ticks. Src kinase, a non-receptor protein-tyrosine kinase, is a major player in cell signaling. Src kinase has an impact on the spread and survival of A. phagocytophilum in ticks. Studies on Src kinase in I. scapularis show that there is a downregulation of Src in unfed ticks and an upregulation after tick feeding. These results show that Src kinase is manipulated differentially by this bacterium for its survival in the vector host and during transmission from vertebrate host to ticks. Furthermore, RNAi-mediated interference of arthropod src kinase gene expression or inhibition of Src kinase activity by inhibitor treatment resulted in dramatic reduction in bacterial loads in ticks and tick cells. Collectively, the findings from this study show that Src kinase plays a major role in tick-A. phagocytophilum interactions. Understanding the role of Src kinase in tick-A. phagocytophilum interactions could lead to identification of vaccine targets that eventually could lead to preventing the spread of this disease.
Liquid jet impingement on a moving wall

Publisher: name: University of British Columbia

description: This research studies the impingement of a free surface Newtonian liquid jet on a dry solid moving wall using theoretical, numerical and experimental methods. The study focus mainly on the parameter range of jet Reynolds numbers 100< Reⱼ <1000 and the wall-to-jet velocity ratios 0.04<uw/vⱼ <30, where the effect of surface tension is negligible, and the major impingement regimes are splash and deposition, although cases with a wider parameter range are probed through CFD or experiments to identify the limit of the proposed theory. First, the 2D (slot or planar) jet impingement problem is explored. A regime diagram based on Reⱼ and uw/vⱼ is established using CFD, and four regimes are identified: splash, steady deposition with a heel, steady deposition with a heel with bumps, and unsteady deposition. A semi-empirical model based on the boundary layer theory and the Karman-Pohlhausen averaging scheme is developed to describe the flow of the steady heel regime. The model provides full solutions for the interface profile, boundary layer thickness, and the velocity field for a given the parameter setting of Reⱼ and uw/vⱼ, and the model predictions agree well with CFD. A second model using the time-dependent boundary-layer equations is developed to rationalize the spreading dynamics of the shallow film, which provides explanations on why the steady state disappears when uw/vⱼ < 2 or when uw/vⱼ is too large. Then, the study advances to the 3D (circular) jet impingement problem. Experiments are conducted using a custom apparatus with high speed imaging technique that map out the regime diagram based on Reⱼ and uw/vⱼ and measure the geometry of the impinging jet. The experiments are complemented with numerical simulations, which reveal the anatomy of the spreading film (lamella) and aid the development of a theoretical model. The model predicts the dimensions of the lamella (the length of the upstream heel and the width of the downstream lamella), and that the shape takes a universal form when scaled by one of these distances. These predictions agree well with the experiments and simulations provided that a lamella exists.
