description: Microscopic relaxation timescales are estimated from the autocorrelation functions obtained by dynamic light scattering experiments for Laponite suspensions with different concentrations ($C_{L}$), added salt concentrations ($C_{S}$) and temperatures ($T$). It has been shown in an earlier work [Soft Matter, 10, 3292-3300 (2014)] that the evolutions of relaxation timescales of colloidal glasses can be compared with molecular glass formers by mapping the waiting time ($t_{w}$) of the former with the inverse of thermodynamic temperature ($1/T$) of the latter. In this work, the fragility parameter $D$, which signifies the deviation from Arrhenius behavior, is obtained from fits to the time evolutions of the structural relaxation timescales. For the Laponite suspensions studied in this work, $D$ is seen to be independent of $C_{L}$ and $C_{S}$, but is weakly dependent on $T$. Interestingly, the behavior of $D$ corroborates the behavior of fragility in molecular glass formers with respect to equivalent variables. Furthermore, the stretching exponent $β$, which quantifies the width $w$ of the spectrum of structural relaxation timescales is seen to depend on $t_{w}$. A hypothetical Kauzmann time $t_{k}$, analogous to the Kauzmann temperature for molecular glasses, is defined as the timescale at which $w$ diverges. Corresponding to the Vogel temperature defined for molecular glasses, a hypothetical Vogel time $t^{\infty}_α$ is also defined as the time at which the structural relaxation time diverges. Interestingly, a correlation is observed between $t_{k}$ and $t^{\infty}_α$, which is remarkably similar to that known for fragile molecular glass formers. A coupling model that accounts for the $t_{w}$-dependence of the stretching exponent is used to analyse and explain the observed correlation between $t_{k}$ and $t^{\infty}_α$.

description: To reduce the consumption of firewood for cooking and to realise recycling-driven soil fertility management, three projects in Northwest Tanzania aim to provide the local smallholder community with cooking and sanitation alternatives. The present study proposes an integrated approach to assess the sustainability of the small-scale cooking and sanitation technologies. Based on the multi-criteria decision support approach (MC(D)A), we developed a decision-specific, locally adapted, and participatory assessment tool: the Multi-Criteria Technology Assessment (MCTA). Pre-testing of the tailored tool was set up with representatives of Tanzanian and German partners of case study projects. From a methodological perspective, we conclude that the MCTA uses a set of relevant criteria to realise a transparent and replicable computational Excel-tool. The combination of MC(D)A for structuring the assessment with analytical methods, such as Material Flow Analysis, for describing the performance of alternatives is a promising path for designing integrated approaches to sustainability assessments of technologies. Pre-testing of the tool served as a proof-of-concept for the general design of the method. Future applications and adjustments of the MCTA require the inclusion of end-users, a reasonable and participatory reduction of criteria, and an increase of feedback loops and group discussions between participants and the facilitator to support a common learning about the technologies and thorough understanding of the perspectives of participants.

description: Surge-type glaciers experience cyclical variations between long periods of slow flow, followed by shorter periods of rapid flow. These glaciers have been thoroughly analysed in many regions, but detailed studies of surging in the Canadian Arctic are lacking. This thesis provides the first comprehensive reconstruction of the dynamics of Iceberg and Airdrop glaciers, located on western Axel Heiberg Island, and reveals detailed observations of a surge for the first time in the Canadian Arctic. A variety of remotely sensed data, including historical aerial photographs, declassified intelligence satellite photographs, optical satellite imagery (e.g., ASTER, Landsat), and synthetic aperture radar data (e.g., ERS-1, ERS-2) were used to quantify changes in terminus position, ice velocity, and ice thickness since the 1950s. A surge initiated at the terminus of Iceberg Glacier in 1981 and terminated in 2003, suggesting an active phase length of 22 years. High surface velocities, peaking at ~2300 m a⁻¹ at the terminus in summer 1991, were accompanied by a terminus advance of >7 km over the period 1981-1997 and a large transfer of mass down-glacier, causing significant median surface elevation changes reaching >3 ± 1 m a⁻¹ across the entire trunk width. The ensuing quiescent period has seen a continual decrease in flow rates to an average centreline velocity of 11.5 m a⁻¹ in 2020-2021, a gradual steepening of the glacier surface, and a terminus retreat of >2.5 km. Observations on Airdrop Glacier show a continuous advance totalling ~6 km since 1950 and notably less variability in its surface velocities in comparison to Iceberg Glacier. This advance can be attributed to consistently high flow rates of Airdrop’s entire surface, resulting in significant thickening near its terminus since at least 1977. However, velocities have more than halved within the last 15 years, but without any clear evidence of previous fast flow events, we cannot confirm whether Airdrop’s behaviour is cyclic in nature and therefore characteristic of a surge. Instead, Airdrop Glacier could be experiencing a delayed response to positive mass balance conditions of the Little Ice Age, and its recent slowdown could be indicative of a gradual adjustment to recent climatic conditions.

description: Measuring the thermodynamic properties of open quantum systems poses a major challenge. A calorimetric detection has been proposed as a feasible experimental scheme to measure work and fluctuation relations in open quantum systems. However, the detection requires a finite size for the environment, which influences the system dynamics. This process cannot be modeled with the standard stochastic approaches. We develop a quantum jump model suitable for systems coupled to a finite-size environment. With the method we study the common fluctuation relations and prove that they are satisfied.

description: Existing scholarship in public sector results-based management (RBM) mostly conceptualizes implementation as an isomorphic process. Researchers frequently look at implementation from a top-down driven approach which conjures images of public servants as automatons who merely sustain RBM practices due to institutional pressures on behaviour. To that effect, little is known around how agency dynamically intersects with institutions not only to maintain, but also to create and disrupt RBM institutions through implementation. Combining institutional pressures and institutional work as theoretical frameworks, this study deploys qualitative content analysis on institutional instruments such as archival materials, as well as semi-structured interviews with Chief Results and Delivery Officers (CRDOs), to identify the various institutional pressures acting on public servants, the different types of institutional work activities performed during implementation of the Results Agenda, and how such actions contribute to the creation, maintenance, and disruption of institutional RBM regime within Canadian public sector. The agency of public servants bears heavily on how CRDOs perceive, understand, and respond to implementation pressures from institutional Results Agenda. The study finds that Results Agenda implementation is not a straightforward, linear, and exclusively top-down political and administrative centre driven activity. CRDOs overwhelmingly perform nuanced and overt actions that at times support, build on, and confront institutional Results Agenda imposed by the centres. This unique and evolving dynamic between institutions and agency intentionally and unintentionally reproduces, maintains, and alters institutional Results Agenda features within Canadian federal public sector. Given the importance of RBM systems in Canada’s federal public organisations, the insights from this study can shed light on how public servants implement institutional RBM and create, maintain, and disrupt centre driven institutional RBM through agency. Finally, this dissertation advances the methodological utility of integrating institutional work for combined empirical and interpretive social action research on institutional RBM implementation.

description: We report on a new source of in-plane anisotropy in nanomagnets due to the presence of Dzyaloshinskii-Moriya interaction (DMI). This anisotropy depends on the shape of the magnet, and is orthogonal to the demagnetization shape anisotropy. This effect originates from the DMI energy reduction due to an out-of-plane tilt of the spins at edges oriented perpendicular to the magnetization. Our investigation combining experimental, numerical and analytical results demonstrate that this energy reduction can compensate the demagnetization shape anisotropy energy in magnets of elongated shape, provided that their volumes is small enough and thus that their magnetization is quasi-uniform.

Contrasting Glacier Behaviour, and Methods for Monitoring Glacier Change, in the Northern Canadian Arctic Archipelago

description: Glaciers are generally considered to be important indicators of climate, but the variability in glacier behaviour observed across the Canadian Arctic Archipelago (CAA) indicates that not all ice masses respond in the same way to external forcing. This thesis presents detailed studies on the contrasting behaviour of two ice masses with widely different characteristics: Good Friday Glacier on western Axel Heiberg Island, a large marine-terminating outlet glacier which has undergone an uninterrupted advance over the last seven decades, and Bowman Glacier in Tanquary Fiord, northern Ellesmere Island, a small mountain glacier destined to disappear within a few decades. Changes of these glaciers are determined from field and remote sensing observations, with a particular focus on digital photogrammetry techniques applied to recent and historical aerial photography for generating topographic datasets. Strategies are presented for the flexible acquisition of high-resolution topographic data in challenging field conditions, typical of high arctic glacier environments, and a workflow is described for deriving detailed surface reconstructions, yielding centimetre-scale digital elevation models and orthomosaics of a small ice mass in the CAA. This work also demonstrates the application of current digital photogrammetry processing for deriving surface elevation information from historical aerial photography from the 1950s, enabling direct comparison with recent topographic products to calculate glacier volume change and geodetic mass balance over decadal timescales. Observations on Good Friday Glacier show a continuous advance totalling >9 km since the late 1940s, representing a 5% increase in glacier area over a total basin size of 800 km², and ice flow rates higher than on most other marine-terminating glaciers in the CAA. In contrast, since 1959, Bowman Glacier lost 78% of its area and 60% of its volume and currently covers only 0.61 km². Projecting the trend in ice extent and surface thinning observed over the last decade indicates that Bowman Glacier will likely disappear entirely between 2030-60. While the ongoing advance of Good Friday Glacier is out of sync with current climatic conditions, changes at Bowman Glacier are in agreement with the dominant regional trend of accelerated mass loss and glacier retreat.
Spectral Gap Analysis for Efficient Tunneling in Quantum Adiabatic Optimization

description: We investigate the efficiency of Quantum Adiabatic Optimization when overcoming potential barriers to get from a local to a global minimum. Specifically we look at n qubit systems with symmetric cost functions f:{0, 1}^n->R where the ground state must tunnel through a potential barrier of width n^a and height n^b. By the quantum adiabatic theorem the time delay sufficient to ensure tunneling grows quadratically with the inverse spectral gap during this tunneling process. We analyze barrier sizes with 1/2 < a + b and a < 1/2 and show that the minimum gap scales polynomially as n^{1/2-a-b} when 2a+b < 1 and exponentially as n^{-b/2} exp(-C n^{(2a+b-1)/2} ) when 1 < 2a+b. Our proof uses elementary techniques and confirms and extends an unpublished folklore result by Goldstone, which used large spin and instanton methods. Parts of our result also refine recent results by Kong and Crosson and Jiang et al. about the exponential gap scaling.

The bright planetary nebulae from the bulge of the Milky Way are entirely compatible with those observed in the discs of spiral galaxies. The similarity might be explained if the bulge of the Milky Way evolved secularly from the disc, in which case the bulge should be regarded as a pseudo-bulge.

description: The Video Browser Showdown evaluates the performance of exploratory video search tools on a common data set in a common environment and in presence of the audience. The main goal of this competition is to enable researchers in the field of interactive video search to directly compare their tools at work. In this paper, we present results from the second Video Browser Showdown (VBS2013) and describe and evaluate the tools of all participating teams in detail. The evaluation results give insights on how exploratory video search tools are used and how they perform in direct comparison. Moreover, we compare the achieved performance to results from another user study where 16 participants employed a standard video player to complete the same tasks as performed in VBS2013. This comparison shows that the sophisticated tools enable better performance in general, but for some tasks common video players provide similar performance and could even outperform the expert tools. Our results highlight the need for further improvement of professional tools for interactive search in videos.

description: Surgical correction of myogenic ptosis is a sophisticated endeavor, as the disease is progressive and the post-operative course is prone to significant complications. We sought to review the literature for repair techniques in different types of myogenic ptosis. A PubMed/MEDLINE literature search of publications pertaining to surgical outcomes of progressive myogenic ptosis repair was performed. Studies included were original retrospective studies with a minimum of four patients. A total of 27 articles were identified and divided by etiology of myogenic ptosis; either chronic progressive external ophthalmoplegia (CPEO), oculopharyngeal muscular dystrophy (OPMD), myasthenia gravis (MG), or mixed. Surgical techniques predominantly involved levator advancement, levator resection, frontalis sling, blepharoplasty, and Fasanella-Servat. Success rates ranged from 60.5% to 100%. Significant postoperative complications included ptosis recurrence, under-correction, over-correction, keratopathy, lagophthalmos, sling exposure, and sling infection. Like surgical repair for other forms of ptosis, correction of progressive myogenic ptosis is guided by levator excursion. However, myogenic ptosis is especially challenging as it is characterized by worsening ptosis and the loss of protective corneal mechanisms. The goals of care with myogenic ptosis involves repairing ptosis just sufficiently to alleviate visual obstruction while avoiding adverse post-operative complications. This intentional under-correction subsequently increases susceptibility for ptosis recurrence. Myogenic ptosis repair therefore requires delicate balancing between function, sustained repair, and corneal protection.

description: Ship traffic in the Canadian Arctic nearly tripled between 1990 and 2015. Most of that increase happened in Nunavut waters. Between 1990 and 2015 Cambridge Bay had the third highest increase in vessel traffic in Nunavut. This increase can be explained by the increasing number of vessels transiting the Northwest Passage, including passenger ships, pleasure craft, tankers, and general cargo ships. The Government of Canada is developing a network of low-impact marine transportation corridors in the Arctic that encourages marine transportation traffic to use routes that pose less risk and minimize the impact on communities and the environment. The Low Impact Shipping Corridors will be a framework to guide future federal investments to support marine navigation safety in the North, including improved charting and increased hydrography, in partnership with Northerners. The corridors initiative is co-led by Transport Canada, the Canadian Coast Guard, and Canadian Hydrographic Service. Key considerations in the current prioritization of the corridors include identification of Inuit and northerners’ perspectives on 1) the potential impact of marine vessels on marine areas used for cultural and livelihood activities, and on community members; and 2) potential management strategies for the corridors. This report reflects opinions gathered through participatory mapping and focus group discussions with Cambridge Bay community members who were identified by the Ekaluktutiak Hunters and Trappers Organization as key knowledge holders. Analysis was aimed at understanding Inuit and northerners’ perspectives on the potential impact of marine transportation on local marine use areas and community members, and on identification of potential management strategies for the low impact shipping corridors. This report was validated by the research participants.

Scenarios for Gluino Coannihilation

description: We study supersymmetric scenarios in which the gluino is the next-to-lightest supersymmetric particle (NLSP), with a mass sufficiently close to that of the lightest supersymmetric particle (LSP) that gluino coannihilation becomes important. One of these scenarios is the MSSM with soft supersymmetry-breaking squark and slepton masses that are universal at an input GUT renormalization scale, but with non-universal gaugino masses. The other scenario is an extension of the MSSM to include vector-like supermultiplets. In both scenarios, we identify the regions of parameter space where gluino coannihilation is important, and discuss their relations to other regions of parameter space where other mechanisms bring the dark matter density into the range allowed by cosmology. In the case of the non-universal MSSM scenario, we find that the allowed range of parameter space is constrained by the requirement of electroweak symmetry breaking, the avoidance of a charged LSP and the measured mass of the Higgs boson, in particular, as well as the appearance of other dark matter (co)annihilation processes. Nevertheless, LSP masses $m_χ\lesssim 8$~TeV with the correct dark matter density are quite possible. In the case of pure gravity mediation with additional vector-like supermultiplets, changes to the anomaly-mediated gluino mass and the threshold effects associated with these states can make the gluino almost degenerate with the LSP, and we find a similar upper bound.

description: The Covid-19 pandemic showed the community the value of scientific research. But in an age of disinformation and false facts, when public trust in institutions is at record-low levels, does the community still hold trust in medical research and in the bodies and institutions that administer it?In this timely, thought-provoking essay, Professor Warwick Peter Anderson AO explores questions around how medical research funding is valued, awarded and recognised in Australia, and how to better use the evidence from medical research to improve the health of Australians. He interrogates whether there are gaps and biases in the processes for awarding grants, if peer review can be improved, if tougher penalties should apply to those who produce ‘fake’ or misleading science, and how medical researchers can invite the public in to take part in decisions about who receives funding and why. Anderson surveys the international landscape and draws on his own experience as the head of the NHRMC to outline the case for why we need to ensure the public retains its faith in the quality and objectivity of medical research.Offering a range of practical solutions, this essential essay is an impassioned call for higher standards around the conduct of medical research, and due recognition for the wealth of talent among Australian medical researchers.

description: The proinflammatory cytokine interleukin-1β (IL-1β) is known to be upregulated in patients suffering from metabolic syndrome. IL-1β contributes to insulin resistance in obesity and type 2 diabetes, yet its influence on the intestinal microbiome is incompletely understood. The data presented here demonstrate that mice genetically deficient in IL-1β show a specific alteration of intestinal colonisation of a small group of bacteria. Especially Akkermansia muciniphila, a bacterium reported to be inversely associated with obesity, diabetes, cardiometabolic diseases and low-grade inflammation, showed increased colonisation in IL-1β knockout mice. In comparative microarray analysis from mucus scrapings of the colon mucosa of IL-1β knockout and wildtype mice, angiogenin 4 mRNA was strongly reduced in IL-1β knockout animals. Since the presence of angiogenin 4 in the culture medium showed a significant growth inhibition on A. muciniphila which was not detectable for other bacteria tested, IL-1β induced expression of angiogenin 4 is a strong candidate to be responsible for the IL-1β induced suppression of A. muciniphila colonisation. Thus, the data presented here indicate that IL-1β might be the lacking link between inflammation and suppression of A. muciniphila abundance as observed in a variety of chronic inflammatory disorders.

Low impact shipping corridors

description: Ship traffic in the Canadian Arctic nearly tripled between 1990 and 2015. Corridors have been mapped in the Arctic Ocean as part of the Low Impact Shipping Corridors Initiative co-led by Transport Canada, the Canadian Coast Guard, and Canadian Hydrographic Service. Low impact shipping corridors are the current framework for governing shipping in the Canadian Arctic. The intent of the low impact shipping corridors is to reduce the likelihood of marine incidents by providing predictable levels of service to mariners transiting the corridors. Identification of Inuit and northerners’ perspectives on the potential impacts of marine vessels on marine areas used for cultural and livelihood activities, and on community members, and the inclusion of Inuit and northerners’ voices in the development of potential management strategies for the low impact shipping corridors and Arctic marine transportation are key considerations in the current prioritization of the corridors. This report reflects opinions gathered through participatory mapping, focus group discussions, and interviews with Aklavik community members who were identified by local organizations as key knowledge holders. Analyses were aimed at understanding Inuit and northerners’ perspectives on the potential impacts of marine transportation on local marine use areas and community members, and on identification of potential management strategies for the low impact shipping corridors and for Arctic marine vessels management. This report was validated by the research participants.
A Far-Infrared Observational Test of the Directional Dependence in Radiative Grain Alignment

description: The alignment of interstellar dust grains with magnetic fields provides a key method for measuring the strength and morphology of the fields. In turn, this provides a means to study the role of magnetic fields from diffuse gas to dense star-forming regions. The physical mechanism for aligning the grains has been a long-term subject of study and debate. The theory of radiative torques, in which an anisotropic radiation field imparts sufficient torques to align the grains while simultaneously spinning them to high rotational velocities, has passed a number of observational tests. Here we use archival polarization data in dense regions of the Orion molecular cloud (OMC-1) at 100, 350, and $850\,μ$m to test the prediction that the alignment efficiency is dependent upon the relative orientations of the magnetic field and radiation anisotropy. We find that the expected polarization signal, with a 180-degree period, exists at all wavelengths out to radii of 1.5 arcminutes centered on the BNKL object in OMC-1. The probabilities that these signals would occur due to random noise are low ($\lesssim$1\%), and are lowest towards BNKL compared to the rest of the cloud. Additionally, the relative magnetic field to radiation anisotropy directions accord with theoretical predictions in that they agree to better than 15 degrees at $100\,μ$m and 4 degrees at $350\,μ$m.

description: We demonstrate how a toroidal Bose-Einstein condensate with a movable barrier can be used to realize an atomtronic SQUID. The magnitude of the barrier height, which creates the analogue of an SNS junction, is of crucial importance, as well as its ramp-up and -down protocol. For too low of a barrier, the relaxation of the system is dynamically suppressed, due to the small rate of phase slips at the barrier. For a higher barrier, the phase coherence across the barrier is suppressed due to thermal fluctuations, which are included in our Truncated Wigner approach. Furthermore, we show that the ramp-up protocol of the barrier can be improved by ramping up its height first, and its velocity after that. This protocol can be further improved by optimizing the ramp-up and ramp-down time scales, which is of direct practical relevance for on-going experimental realizations.

description: The Lower Carboniferous carbonate sediments of the Mobarak Formation have been analysed to evaluate the role of allogenic and autogenic factors on the development of a distally steepened carbonate platform. Thirteen facies are identified in the studied succession and are grouped into four facies associations: inner ramp FA‒FB; middle ramp FC; ramp slope FD; and deep ramp FE. The rifting event at the northern margin of the Gondwana supercontinent caused a remarkable change in the depositional system so that the precursor homoclinal ramp (Khosheilagh Formation, Devonian) turned into the distally steepened ramp of the Mobarak Formation. Six depositional sequences are identified in the succession, characterized by varieties the normal transgression‒regression cycles, the TST‒HST, or the transgression‒forced regression cycles consisting of the TST‒HST‒FSST. The main controlling elements in the stacking pattern of sedimentary packages, relative sea-level changes and the formation of depositional sequences were tectonic activity and eustatic sea-level changes. Development of the FSST package was caused by the increasing tectonic activity and the formation of turbiditic sediments, amplified by wave-induced currents as the autogenic factor on formation of the re-sedimented deposits. Development of the HST deposits displays a relative balance between sedimentation rate and the creation of accommodation space. Thick packages of deep ramp calcareous shale were developed during quiescence in the tectonic activity and increase in accommodation space, created by thermal subsidence and rise in eustatic sea-level.
