description: The Liouville theorem states that the phase-space volume of an ensemble in a closed system remains constant. While gases of material particles can efficiently be cooled by sympathetic or laser cooling techniques, allowing for large phase-space compression, for light both the absence of an internal structure, as well as the usual non-conservation of particle number upon contact to matter imposes fundamental limits e.g. in fluorescence-based light concentrators in three-dimensional systems. A different physical situation can in principle be expected for dye-solution filled microcavities with a mirror spacing in the wavelength range, where low dimensional photon gases with non-vanishing, freely tunable chemical potential have been experimentally realized. Motivated by the goal to observe phase-space compression of sunlight by cooling the captured radiation to room temperature, we in this work theoretically show that in a lossless system the phase space volume scales as $(Δx Δp / T)^d = \mathrm{constant}$, where $Δx$ and $Δp$ denote the rms position and momentum spread and $d$ the dimensionality of the system ($d=1$ or $2$). We also experimentally realize a sunlight pumped dye microcavity, and demonstrate thermalization of scattered sunlight to a two-dimensional room temperature ensemble with non-vanishing chemical potential. Prospects of phase space buildup of light by cooling, as can be feasible in systems with a two- or three-dimensional band gap, can range from quantum state preparation in tailored potentials up to technical applications in diffuse sunlight collection.
Impact of regulatory frameworks on informal cross border trade in Nigeria : a case study of the rice import restriction and border closure of 2019
Creators: name: Omotosho, Mariam Ololade

description: Informal cross border trade (ICBT) appears to be neglected in trade policy discussions in Nigeria and Africa despite its enormous contribution to income earnings and food security. Regulatory policies often perceive ICBT as a social and economic threat. Hence, government policies often focus on the formal traders, neglecting the challenges encountered by informal cross border traders. ICBT constitutes the bulk of the informal economy and comprises vulnerable, small traders who use informal channels for trade as a result of non-inclusive government policies. Failure to develop regulations and policies that incorporate the realities of informal cross border traders is costly to both the ICBT actors and the government. First, a significant portion of government revenue is lost to ICBT in unpaid customs duties and tax. Second, existing policies continue to exclude traders involved in ICBT, preventing them from benefiting from incentives and other trade facilitation initiatives by the government. Excluding informal cross border traders in trade policy discussions undermines the profitability of cross border trade for all economic actors. This research combines a theory-driven approach with empirical case studies to evaluate the impact of regulatory frameworks on ICBT in Nigeria. Examining the rice import restriction and border closure policies implemented in 2019, this thesis demonstrates that (i) the trade regulatory framework in Nigeria is non-inclusive of ICBT, (ii) hostility and non-inclusion further drives informality in cross border trade in Nigeria, and in Africa, and, (iii) ICBT actors are crucial to building effective trade regulatory frameworks. By identifying the ideological gaps in the current regulatory framework, I propose a reform to the cross border trade regulatory framework in Nigeria. I also identify the gaps in regional trade regulatory frameworks. The empirical case studies corroborate the need for a reform in the approach to cross border trade regulation. The analysis of trade data from the case studies reveals the inadequacy and ineffectiveness of the current framework.

description: We constrain the Hubble constant H$_0$ using Fast Radio Burst (FRB) observations from the Australian Square Kilometre Array Pathfinder (ASKAP) and Murriyang (Parkes) radio telescopes. We use the redshift-dispersion measure (`Macquart') relationship, accounting for the intrinsic luminosity function, cosmological gas distribution, population evolution, host galaxy contributions to the dispersion measure (DM$_{\rm host}$), and observational biases due to burst duration and telescope beamshape. Using an updated sample of 16 ASKAP FRBs detected by the Commensal Real-time ASKAP Fast Transients (CRAFT) Survey and localised to their host galaxies, and 60 unlocalised FRBs from Parkes and ASKAP, our best-fitting value of H$_0$ is calculated to be $73_{-8}^{+12}$ km s$^{-1}$ Mpc$^{-1}$. Uncertainties in FRB energetics and DM$_{\rm host}$ produce larger uncertainties in the inferred value of H$_0$ compared to previous FRB-based estimates. Using a prior on H$_0$ covering the 67--74 km s$^{-1}$ Mpc$^{-1}$ range, we estimate a median DM$_{\rm host} = 186_{-48}^{+59}$ km s$^{-1}$ Mpc$^{-1}$, exceeding previous estimates. We confirm that the FRB population evolves with redshift similarly to the star-formation rate. We use a Schechter luminosity function to constrain the maximum FRB energy to be $\log_{10} E_{\rm max}=41.26_{-0.22}^{+0.27}$ erg assuming a characteristic FRB emission bandwidth of 1 GHz at 1.3 GHz, and the cumulative luminosity index to be $γ=-0.95_{-0.15}^{+0.18}$. We demonstrate with a sample of 100 mock FRBs that H$_0$ can be measured with an uncertainty of $\pm 2.5$ km s$^{-1}$ Mpc$^{-1}$, demonstrating the potential for clarifying the Hubble tension with an upgraded ASKAP FRB search system. Last, we explore a range of sample and selection biases that affect FRB analyses.

description: Lorentz-invariant scalar field theories in d+1 dimensions with second-order derivative terms are unable to support static soliton solutions that are both finite in energy and stable for d>2, a result known as Derrick's theorem. Lifshitz theories, which introduce higher-order spatial derivatives, need not obey Derrick's theorem. We construct stable, finite-energy, static soliton solutions in Lifshitz scalar field theories in 3+1 dimensions with dynamical critical exponent z=2. We exhibit three generic types: non-topological point defects, topological point defects, and topological strings. We focus mainly on Lifshitz theories that are defined through a superpotential and admit BPS solutions. These kinds of theories are the bosonic sectors of supersymmetric theories derived from the stochastic dynamics of a scalar field theory in one higher dimension. If nature obeys a Lifshitz field theory in the ultraviolet, then the novel topological defects discussed here may exist as relics from the early universe. Their discovery would prove that standard field theory breaks down at short distance scales.

description: The first LHC pp collisions at centre-of-mass energies of 0.9 and 2.36 TeV were recorded by the CMS detector in December 2009. The trajectories of charged particles produced in the collisions were reconstructed using the all-silicon Tracker and their momenta were measured in the 3.8 T axial magnetic field. Results from the Tracker commissioning are presented including studies of timing, efficiency, signal-to-noise, resolution, and ionization energy. Reconstructed tracks are used to benchmark the performance in terms of track and vertex resolutions, reconstruction of decays, estimation of ionization energy loss, as well as identification of photon conversions, nuclear interactions, and heavy-flavour decays.

description: Στην παρούσα διπλωματική εργασία εξετάζεται η περιοχή του Σταυρού Ακρωτηρίου, βορειοανατολικά της πόλης των Χανίων. Πρόκειται για έναν οικισμό παραθερισμού που ξεκίνησε να αναπτύσσεται από την δεκαετία του ‘60 πάνω σε ένα τοπίο με ιδιαίτερο γεωλογικό υπόβαθρο και με βασικά στοιχεία: α.το παράκτιο ενετικό λατομείο, β. τις δύο παραλίες του Σταυρού και της Παχιάς Άμμου, γ. το βουνό Βάρδιες και τις πεζοπορικές διαδρομές του, δ. την απόληξη του ρέματος του κάμπου του ακρωτηρίου, ε. έναν μικρό νησιώτικο υγροβιότοπο.
Μέσα από διαδοχικές αεροφωτογραφίες μελετάται η σταδιακή, εκτός σχεδίου ανάπτυξή του οικισμού, οι πιέσεις που άσκησε στο αρχικό οικοσύστημα και η αποκοπή των σχέσεων μεταξύ των παραπάνω αξιόλογων τόπων. Εμφανίζεται ένας τόπος αντιθέσεων και αναδεικνύεται η ιδιαιτερότητα της περιοχής: από την μία ένας οικισμός με περιορισμένο δημόσιο χώρο και δαιδαλώδες δίκτυο και από την άλλη ένα καταπατημένο φυσικό τοπίο προς ανακάλυψη.
Η δομή και η μορφή του ενετικού λατομείου, ως ένας τόπος στο ενδιάμεσο του φυσικού και του ανθρωπογενούς, ξεχωρίζει ανάμεσα στην έντονη οριζοντιότητα του οικισμού και την κατακορυφότητα του βουνού. Με εργαλείο αυτή την εντύπωση και τη σχέση πλήρους και κενού, η διπλωματική επιχειρεί να επαναπροσδιορίσει τα όρια του οικισμού, δίνοντας χώρο στο φυσικό τοπίο και να αρθρώσει οργανικά τους δύο κόσμους. Οργανώνεται ένα σύστημα αστικών συνδέσεων, δημοσίων κτιριακών υποδομών με χρήσεις πολιτισμού, δημόσιου χώρου και πλατειών, μονοπατιών και ανάδειξης του αρχαιολογικού χώρου της λατόμησης, ενισχύοντας και επαναπροσδιορίζοντας την τοπική ταυτότητα του οικισμού.

description: Recently an idea for computing the entropy of black holes in the spin foam formalism has been introduced. Particularly complete calculations for the three dimensional euclidean BTZ black hole were done. The whole calculation is based on observables living at the horizon of the black hole universe. Departing from this idea of observables living at the horizon, we now go further and compute the entropy of BTZ black hole in the spirit of statistical mechanics. We compare both calculations and show that they are very interrelated and equally valid. This latter behaviour is certainly due to the importance of the observables.

description: Inter-patient abdominal registration has various applications, from pharmakinematic studies to anatomy modeling. Yet, it remains a challenging application due to the morphological heterogeneity and variability of the human abdomen. Among the various registration methods proposed for this task, probabilistic displacement registration models estimate displacement distribution for a subset of points by comparing feature vectors of points from the two images. These probabilistic models are informative and robust while allowing large displacements by design. As the displacement distributions are typically estimated on a subset of points (which we refer to as driving points), due to computational requirements, we propose in this work to learn a driving points predictor. Compared to previously proposed methods, the driving points predictor is optimized in an end-to-end fashion to infer driving points tailored for a specific registration pipeline. We evaluate the impact of our contribution on two different datasets corresponding to different modalities. Specifically, we compared the performances of 6 different probabilistic displacement registration models when using a driving points predictor or one of 2 other standard driving points selection methods. The proposed method improved performances in 11 out of 12 experiments.

description: The Federal Highway Administration’s (FHWA’s) Development of Crash Modification Factors (DCMF) program was established in 2012 to address highway-safety research needs for evaluating new and innovative safety strategies (e.g., improvements) by developing reliable quantitative estimates of their effectiveness in reducing crashes. Forty-one State departments of transportation provide technical feedback on safety improvements to the DCMF program and implement new safety improvements to facilitate evaluations. These States are members of the Evaluation of Low-Cost Safety Improvements Pooled Fund Study (ELCSI-PFS) that functions under the DCMF program. This project evaluated the addition of bicycle lanes achieved by reducing lane and shoulder widths as a safety improvement strategy (e.g., safety intervention). The ELCSI-PFS Technical Advisory Committee selected this evaluation as one of the priorities within its purview.

description: We use Morse theoretical arguments to study algebraic curves in C^2. We take an algebraic curve C in C^2 and intersect it with a family of spheres with fixed origin and varying radii. We explain in detail how does the resulting link change when we cross a singular point of C. Applying link invariants as Murasugi's signature and Levine--Tristram signatures we obtain some informations about possible singularities of a curve C in terms of its topology.

description: While gas accretion onto some massive black holes (MBHs) at the centers of galaxies actively powers luminous emission, the vast majority of MBHs are considered dormant. Occasionally, a star passing too near a MBH is torn apart by gravitational forces, leading to a bright panchromatic tidal disruption flare (TDF). While the high-energy transient Swift J164449.3+573451 ("Sw 1644+57") initially displayed none of the theoretically anticipated (nor previously observed) TDF characteristics, we show that the observations (Levan et al. 2011) suggest a sudden accretion event onto a central MBH of mass ~10^6-10^7 solar masses. We find evidence for a mildly relativistic outflow, jet collimation, and a spectrum characterized by synchrotron and inverse Compton processes; this leads to a natural analogy of Sw 1644+57 with a smaller-scale blazar. The phenomenologically novel Sw 1644+57 thus connects the study of TDFs and active galaxies, opening a new vista on disk-jet interactions in BHs and magnetic field generation and transport in accretion systems.

description: We construct a 2D holographic ionic lattice with hyperscaling-violating infrared geometry and study single-electron spectral functions ("ARPES photoemission curves") on this background. The spectra typically show a three-peak structure, where the central peak undergoes a crossover from a sharp but not Fermi-liquid-like quasiparticle to a wide incoherent maximum, and the broad side peaks resemble the Hubbard bands. These findings are partially explained by a perturbative near-horizon analysis of the bulk Dirac equation. Comparing the holographic Green functions in imaginary frequency with the Green functions of the Hubbard model obtained from quantum Monte Carlo, we find that the holographic model provides a very good fit to the Hubbard Green function. However, the information loss when transposing the holographic Green functions to imaginary frequencies implies that a deeper connection to Hubbard-like models remains questionable.

description: Accurate stellar parameters, Teff and chemical composition, are imperative for the determination of masses, radii, and ages of PLATO stars. I will present the architecture and input physics of the SAPP pipeline that will be used to determine non-seismic stellar parameters for the PLATO core sample.
 In this talk, I will discuss how we cope with rapid yet painstaking developments in stellar atmosphere modelling, including radiation hydrodynamics theory, atomic and molecular physics, machine learning and numerical analysis methods, - the developments that form the basis of the unique diagnostic capabilties of the SAPP. I will highlight our successes and challenges, and close with the prospects for PLATO and other future projects that aim to capitalise on unprecendeted data available from ground- and space-based observations.

description: The topic of the final qualifying work: "Magnetic thickness gauge of induction type". This work is the development of a project of an inductive thickness gauge with a sensing element, which is an inductive coil with a ferromagnetic core. In the course of the work, the following tasks were solved: 1. formulation of the terms of reference; 2. review of existing methods of non-destructive magnetic testing; 3. development of a block diagram; 4. calculation of chain elements; 5. calculation of the parameters of the sensing element; 6. calculation of the errors of the designed device. As a result of the completion of the final qualification work, a prototype of an inductive magnetic thickness gauge was developed that performs control of non-magnetic coatings on ferromagnetic bases.

description: We have developed efficient techniques to solve the first-time problems of Brownian motion. Based on a time-scale separation of recrossings, we show that Eyring's transmission coefficient ($κ$) equals to the one ($κ_\mathrm{V}$) corresponding to an absorbing boundary consistent with the transition state theory, which is greater than the one ($κ_\mathrm{K}$) derived by Kramers. We also propose methods for reaction rate determination by analyzing short-time trajectories from the barrier maximum, and discuss the relation to the reactive flux method and the significance of reaction coordinates.

description: Charge multiplication (CM) in p$^+$n epitaxial silicon pad diodes of 75, 100 and 150 $\upmu$m thickness at high voltages after proton irradiation with 1 MeV neutron equivalent fluences in the order of $10^{16}$ cm$^{-2}$ was studied as an option to overcome the strong trapping of charge carriers in the innermost tracking region of future Super-LHC detectors. Charge collection efficiency (CCE) measurements using the Transient Current Technique (TCT) with radiation of different penetration (670, 830, 1060 nm laser light and $α$-particles with optional absorbers) were used to locate the CM region close to the p$^+$-implantation. The dependence of CM on material, thickness of the epitaxial layer, annealing and temperature was studied. The collected charge in the CM regime was found to be proportional to the deposited charge, uniform over the diode area and stable over a period of several days. Randomly occurring micro discharges at high voltages turned out to be the largest challenge for operation of the diodes in the CM regime. Although at high voltages an increase of the TCT baseline noise was observed, the signal-to-noise ratio was found to improve due to CM for laser light. Possible effects on the charge spectra measured with laser light due to statistical fluctuations in the CM process were not observed. In contrast, the relative width of the spectra increased in the case of $α$-particles, probably due to varying charge deposited in the CM region.

description: Il presente lavoro è incentrato sulla peer education, una forma di educazione tra pari che pone l’allievo al centro dell’azione pedagogica e ha l’obiettivo di attivare il passaggio di conoscenze, emozioni ed esperienze da parte di giovani ad altri giovani (pari). In Ticino come altrove, questo approccio si applica soprattutto nell’ambito della prevenzione di malattie o dipendenze tra gli adolescenti nelle scuole medie o in ordini superiori. Tuttavia, nonostante i comprovati vantaggi, non solo in termini di promozione della salute ma anche nell’acquisizione di Saperi e nello sviluppo di Competenze Trasversali, il suo impiego alle scuole elementari (SE) non è prassi. Nella mia sperimentazione ho condotto un progetto che ha coinvolto la IV elementare della sede di Magliaso per un periodo di 25 settimane, adottando un modello di peer education modificato e adeguato a questa fascia d’età, per valutarne l’efficacia dal punto di vista educativo. Il tema di lavoro riguardava l’aria (percorso di scienze naturali) ed è stato proposto in chiave di Educazione allo Sviluppo Sostenibile. La peer education si è dimostrata efficace e utile anche con gli allievi di SE, nei quali ha contribuito a promuovere l’acquisizione di contenuti disciplinari e a sviluppare identità personale, pensiero critico, consapevolezza ecologica, attitudine cooperativa, creatività e nuove strategie d’apprendimento. Si ritiene pertanto auspicabile in futuro un suo potenziale impiego anche in quest’ordine scolastico.

description: We study the finite temperature phases and collective excitations of hardcore as well as softcore bosons on a square lattice with nearest and next nearest neighbor interactions, focusing on the formation of various types of supersolid (SS) phases and their stability under thermal fluctuations. The interplay between the on-site, nearest, and next nearest neighbor interactions leads to various density ordering and structural transitions, which we have plotted out. Thermodynamic properties and phase diagrams are obtained by cluster mean field theory at finite temperatures, which includes quantum effects systematically, and they are compared with the single-site mean field results. We investigate the melting process of the SS phase to normal fluid (NF), which can occur in at least two steps due to the presence of two competing orders in the SS. A tetra-critical point exists at finite temperature and exhibits intriguing behavior, which is analyzed for different regimes of interactions. The phase diagrams reveal the different pathways of the thermal transition of SSs to the NF phase, for different interaction regimes, which can be accessible by thermal quench protocols used in recent experiments. We show how the phases and the transitions between them can be identified from the characteristic features of the excitation spectrum. We analyze the appearance of a low-energy gapped mode apart from the gapless sound mode in the SS phase, which is analogous to the gapped mode recently studied for dipolar SS phases. Finally, we discuss the relevance of the results of the present work in the context of ongoing experiments on ultracold atomic gases and newly observed SS phases.

description: Linear optics is a promising candidate for the implementation of quantum information processing protocols. In such systems single photons are employed to represent qubits. In practice, single photons produced from different sources will not be perfectly temporally and frequency matched. Therefore understanding the effects of temporal and frequency mismatch is important for characterising the dynamics of the system. In this paper we discuss the effects of temporal and frequency mismatch, how they differ, and what their effect is upon a simple linear optics quantum gate. We show that temporal and frequency mismatch exhibit inherently different effects on the operation of the gate. We also consider the spectral effects of the photo-detectors, focusing on time-resolved detection, which we show has a strong impact on the operation of such protocols.

description: VHS J1256$-$1257 AB is an ultracool dwarf binary that hosts a wide-separation planetary-mass companion that is a key target of the {\sl JWST} Exoplanet Early Release Science (ERS) program. Using Keck adaptive optics imaging and aperture masking interferometry, we have determined the host binary's orbit, $a=1.96\pm0.03$ au, $P=7.31\pm0.02$ yr, $e=0.883\pm0.003$, and measured its dynamical total mass, $0.141\pm0.008$ $M_{\odot}$. This total mass is consistent with VHS J1256$-$1257 AB being a brown dwarf binary or pair of very low-mass stars. In addition, we measured the orbital motion of VHS J1256$-$1257 b with respect to the barycenter of VHS J1256$-$1257 AB, finding that the wide companion's orbit is also eccentric, $e=0.68^{+0.11}_{-0.10}$, with a mutual inclination of $115\pm14^{\circ}$ with respect to the central binary. This orbital architecture is consistent with VHS J1256$-$1257 b attaining a significant mutual inclination through dynamical scattering and thereafter driving Kozai-Lidov cycles to pump the eccentricity of VHS J1256$-$1257 AB. We derive a cooling age of $140\pm20$ Myr for VHS J1256$-$1257 AB from low-mass stellar/substellar evolutionary models. At this age, the luminosity of VHS J1256$-$1257 b is consistent with both deuterium-inert and deuterium-fusing evolutionary tracks. We thus find a bimodal probability distribution for the mass of VHS J1256$-$1257 b, either $12.0\pm0.1$ $M_{\rm Jup}$ or $16\pm1$ $M_{\rm Jup}$, from these models. Future spectroscopic data to measure isotopologues such as HDO and CH$_3$D could break this degeneracy and provide a strong test of substellar models at the deuterium-fusion mass boundary.

description: The imputation of missing values represents a significant obstacle for many real-world data analysis pipelines. Here, we focus on time series data and put forward SSSD, an imputation model that relies on two emerging technologies, (conditional) diffusion models as state-of-the-art generative models and structured state space models as internal model architecture, which are particularly suited to capture long-term dependencies in time series data. We demonstrate that SSSD matches or even exceeds state-of-the-art probabilistic imputation and forecasting performance on a broad range of data sets and different missingness scenarios, including the challenging blackout-missing scenarios, where prior approaches failed to provide meaningful results.

Scanning electron microscopy analysis of biofilm on dental implants explanted due to peri-implantitis
Creators: name: Chang, Jae Wook
Publisher: name: University of British Columbia
Year: 2021

description: Background: About 20% of subjects receiving implants develop peri-implantitis (PI) that associates with progressive inflammation and bone loss around implants, often leading to implant failure. PI is caused by bacteria that accumulate in peri-implant space but the consensus on microbial profile is still lacking. Microbial sampling of PI lesions has largely focused on analyzing bacterial species that have been shed from implant surface and captured in the pocket fluid. The purpose of the present study was to investigate the morphotypes of bacteria in microbial ecosystem that covers the implant threads and explore whether different brands of implants favor different morphotypes and whether certain morphotypes were associated with more advanced disease. Methods: The implants (N=14) that were determined to have failed by the clinician were removed and instantly processed for scanning electron microscope analysis. The implants were imaged at three equally divided levels of the exposed area due to diseased bone loss. Bacterial morphotypes [cocci, rods, filaments, spirilla/spirochetes] in each level were further analyzed at higher magnification to enable identification and quantification by three examiners. The different types of surfaces, mobility and years in functions were correlated to the presence of specific morphotypes. Results: Implants removed due to PI demonstrated the presence of variable bacterial morphotypes that did not correlate to disease progression in our preliminary study. Some implants were dominated by filaments and others showed the presence of combinations of cocci and rods or mixed morphotypes of spirilles/spirochetes. Rods and filaments were dominant species throughout the surfaces and cocci showed increased presence towards the apical third compared to coronal and middle thirds. There were significant differences in the morphotypes in the implants with TiUnite and SLA surfaces (except for cocci), with mobility and with more than 10 years of function. Conclusions: The profiles of morphotypes in biofilms of different implants with similar clinical presentation of PI were highly variable and did not clearly associate with implant brand. While there were significant differences between implants, interestingly, similar morphotypes on individual implants were found throughout the entire implant surface.

description: We present a statistically complete sample of very X-ray luminous galaxy clusters detected in the MAssive Cluster Survey (MACS). This second MACS release comprises all 34 MACS clusters with nominal X-ray fluxes in excess of 2x10^(-12) erg/s/cm^2 (0.1-2.4 keV) in the ROSAT Bright Source Catalogue; two thirds of them are new discoveries. Extending over the redshift range from 0.3 to 0.5, this subset complements the complete sample of the 12 most distant MACS clusters (z>0.5) published in 2007 and further exemplifies the efficacy of X-ray selection for the compilation of samples of intrinsically massive galaxy clusters. Extensive follow-up observations with Chandra/ACIS led to three additional MACS cluster candidates being eliminated as (predominantly) X-ray point sources. For another four clusters --- which, however, remain in our sample of 34 --- the point-source contamination was found to be about 50%. The median X-ray luminosity of 1.3x10^45 erg/s (0.1-2.4 keV, Chandra, within r_500) of the clusters in this subsample demonstrates the power of the MACS survey strategy to find the most extreme and rarest clusters out to significant redshift. A comparison of the optical and X-ray data for all clusters in this release finds a wide range of morphologies with no obvious bias in favour of either relaxed or merging systems.
