description: Extrasolar analogues of the Solar System's Kuiper belt offer unique constraints on outer planetary system architecture. Radial features such as the sharpness of disk edges and substructures such as gaps may be indicative of embedded planets within a disk. Vertically, the height of a disk can constrain the mass of embedded bodies. Edge-on debris disks offer a unique opportunity to simultaneously access the radial and vertical distribution of material, however recovering either distribution in an unbiased way is challenging. In this study, we present a non-parametric method to recover the surface brightness profile (face-on surface brightness as a function of radius) and height profile (scale height as a function of radius) of azimuthally symmetric, edge-on debris disks. The method is primarily designed for observations at thermal emission wavelengths, but is also applicable to scattered light observations under the assumption of isotropic scattering. By removing assumptions on underlying functional forms, this algorithm provides more realistic constraints on disk structures. We also apply this technique to ALMA observations of the AU Mic debris disk and derive a surface brightness profile consistent with estimates from parametric approaches, but with a more realistic range of possible models that is independent of parametrisation assumptions. Our results are consistent with a uniform scale height of 0.8 au, but a scale height that increases linearly with radius is also possible.

description: A magneto-hydrostatic model is constructed with spectropolarimetric properties close to those of solar photospheric magnetic bright points. Results of solar radiative magneto-convection simulations are used to produce the spatial structure of the vertical component of the magnetic field. The horizontal component of magnetic field is reconstructed using the self-similarity condition, while the magneto-hydrostatic equilibrium condition is applied to the standard photospheric model with the magnetic field embedded. Partial ionisation processes are found to be necessary for reconstructing the correct temperature structure of the model. The structures obtained are in good agreement with observational data. By combining the realistic structure of the magnetic field with the temperature structure of the quiet solar photosphere, the continuum formation level above the equipartition layer can be found. Preliminary results are shown of wave propagation through this magnetic structure. The observational consequences of the oscillations are examined in continuum intensity and in the Fe I 6302Å magnetically sensitive line.

description: The LAT instrument on the Fermi mission will reveal the rich spectral and temporal gamma-ray burst phenomena in the > 100 MeV band. The synergy with Fermi's GBM detectors will link these observations to those in the well explored 10-1000 keV range; the addition of the > 100 MeV band observations will resolve theoretical uncertainties about burst emission in both the prompt and afterglow phases. Trigger algorithms will be applied to the LAT data both onboard the spacecraft and on the ground. The sensitivity of these triggers will differ because of the available computing resources onboard and on the ground. Here we present the LAT's burst detection methodologies and the instrument's GRB capabilities.

description: Nonalcoholic fatty liver disease (NAFLD) encompasses a spectrum of disease from simple steatosis to nonalcoholic steatohepatitis, with inflammatory cytokines and adipokines identified as drivers of disease progression. Poor dietary patterns are known to promote an inflammatory milieu, although the effects of specific diets remain largely unknown. This review aimed to gather and summarize new and existing evidence on the effect of dietary intervention on inflammatory markers in patients with NAFLD. The electronic databases MEDLINE, EMBASE, CINAHL, and Cochrane were searched for clinical trials which investigated outcomes of inflammatory cytokines and adipokines. Eligible studies included adults >18 y with NAFLD, which compared a dietary intervention with an alternative diet or control (no intervention) group or were accompanied by supplementation or other lifestyle interventions. Outcomes for inflammatory markers were grouped and pooled for meta-analysis where heterogeneity was allowed. Methodological quality and risk of bias were assessed using the Academy of Nutrition and Dietetics Criteria. Overall, 44 studies with a total of 2579 participants were included. Meta-analyses indicated intervention with an isocaloric diet plus supplement was more effective in reducing C-reactive protein (CRP) [standard mean difference (SMD): 0.44; 95% CI: 0.20, 0.68; P = 0.0003] and tumor necrosis factor-alpha (TNF-α) (SMD: 0.74; 95% CI: 0.02, 1.46; P = 0.03) than an isocaloric diet alone. No significant weighting was shown between a hypocaloric diet with or without supplementation for CRP (SMD: 0.30; 95% CI: −0.84, 1.44; P = 0.60) and TNF-α (SMD: 0.01; 95% CI: −0.43, 0.45; P = 0.97). In conclusion, hypocaloric and energy-restricted diets alone or with supplementation, and isocaloric diets with supplementation were shown to be most effective in improving the inflammatory profile of patients with NAFLD. To better determine the effectiveness of dietary intervention alone on a NAFLD population, further investigations of longer durations, with larger sample sizes are required.
The no-free-lunch theorems of supervised learning

Year: 2022
Subjects: subject: Machine Learning (cs.LG)
subject: FOS: Computer and information sciences

description: The no-free-lunch theorems promote a skeptical conclusion that all possible machine learning algorithms equally lack justification. But how could this leave room for a learning theory, that shows that some algorithms are better than others? Drawing parallels to the philosophy of induction, we point out that the no-free-lunch results presuppose a conception of learning algorithms as purely data-driven. On this conception, every algorithm must have an inherent inductive bias, that wants justification. We argue that many standard learning algorithms should rather be understood as model-dependent: in each application they also require for input a model, representing a bias. Generic algorithms themselves, they can be given a model-relative justification.
Star Formation in Relic HII Regions of the First Stars: Binarity and Outflow Driving

description: Star formation in relic HII regions of the first stars is investigated using magneto-hydrodynamical simulations with a nested grid method that covers 10 orders of magnitude in spatial scale and 20 orders of magnitude in density contrast. Due to larger fraction of H_2 and HD molecules, its prestellar thermal evolution is considerably different from that in the first star formation. Reflecting the difference, two hydrostatic cores appear in a nested manner: a protostar is enclosed by a transient hydrostatic core, which appears during the prestellar collapse. If the initial natal core rotates fast at a rate with rotational to gravitational energy ratio β_0 > 0.01-0.1, the transient hydrostatic core fragments to \sim 10 M_\odot sub-cores at density \sim 10^9 cm^-3. With smaller rotation energy, fragmentation occurs at higher density while a single protostar forms without fragmentation if rotation is extremely slow with β_0 < 10^-6 -10^-5. If magnetic field is present, these threshold values of β_0 is boosted owing to angular momentum transport by the magnetic breaking. Magnetic field also drives the protostellar outflows. With strong magnetic field, two distinct outflows are observed: The slower one emanates from the transient hydrostatic core, while the faster one from the protostar. These flows may affect the final stellar mass by ejecting some of masses in the initial core, and also may play some role in driving and maintenance of interstellar turbulence in young galaxies.

Development of an intraoperative planning and guidance system for mandibular reconstruction
Creators: name: Yu, Melissa
Publisher: name: University of British Columbia
Year: 2024

description: Mandibular reconstruction with a fibula free flap is a common method for restoring form and function to patients with segmental mandible defects. The conventional strategy for reconstruction is a freehand technique, but this makes it difficult to achieve adequate contact between bone segments. More recent technology uses virtual surgical planning to 3D print cutting guides. However, this process can take days to weeks of preparation, during which the tumour can progress beyond the resection margins, rendering the initial plan obsolete. A day-of-surgery approach combats this limitation using image guidance to bring surgical planning into the operating room. This provides surgeons with the flexibility to respond to intraoperative changes while maintaining the benefits of guided approaches. A proof-of-concept system was developed by previous graduate students that demonstrated comparable accuracy to 3D printed guides but significantly prolonged the operative time. Therefore, the objective of this work is to prepare the day-of-surgery approach for clinical implementation by addressing the key limitations of the existing system. This thesis details our efforts to reduce its intraoperative time, update its virtual surgical planning (VSP) algorithm, and introduce guided navigation to support segment positioning. We used a motor cognitive modelling diagram to identify areas of inefficiency within the integrated procedure and inform usability improvements to the software workflow. We also updated the VSP algorithm to align with the version developed by the ISTAR group to automate surgical planning and support future dental implant considerations. We then used this VSP to guide a surgeon through the precise micromanipulator adjustments required to move a segment into its target position. These changes were evaluated by ENT surgeons through a simulated mandibular reconstruction procedure on anatomical models. We generated five reconstructions with comparable accuracy to the previous cadaver study, and reduced operative time to an average of only 215 minutes. This represents a key step towards its clinical implementation by demonstrating that the day-of-surgery system can be implemented into mandibular reconstruction surgery without introducing significant delays to the operation.

description: We study the exact solution for two atomic particles in an optical lattice interacting via a Feshbach resonance. The analysis includes the influence of all higher bands, as well as the proper renormalization of molecular energy in the closed channel. Using an expansion in Bloch waves, we show that the problem reduces to a simple matrix equation, which can be solved numerically very efficient. This exact solution allows for the precise determination of the parameters in the Hubbard model and the two-particle bound state energy. We identify the regime, where a single band Hubbard model fails to describe the scattering of the atoms as well as the bound states.

title: Elements of Unsupervised Scene Understanding: Objectives, Structures, and Modalities
Creators: name: Stelzner, Karl
Publisher: name: UNSPECIFIED
Year: 2023

description: Enabling robust interactions between automated systems and the real world is a major goal of artificial intelligence. A key ingredient towards this goal is scene understanding: the ability to process visual imagery into a concise representation of the depicted scene, including the identity, position, and geometry of objects. While supervised deep learning approaches have proven effective at processing visual inputs, the cost of supplying human annotations for training quickly becomes infeasible as the diversity of the inputs and the required level of detail increases, putting full real-world scene understanding out of reach.

For this reason, this thesis investigates unsupervised methods to scene understanding. In particular, we utilize generative models with structured latent variables to facilitate the learning of object-based representations. We start our investigation in an autoencoding setting, where we highlight the capability of such systems to identify objects without human supervision, as well as the advantages of integrating tractable components within them. At the same time, we identify some limitations of this setting, which prevent success in more visually complex environments. Based on this, we then turn to video data, where we leverage the prediction of dynamics to both regularize the representation learning task and to enable applications to reinforcement learning. Finally, to take another step towards a real world setting, we investigate the learning of representations encoding 3D geometry. We discuss various methods to encode and learn about 3D scene structure, and present a model which simultaneously infers the geometry of a given scene, and segments it into objects.

We conclude by discussing future challenges and lessons learned. In particular, we touch on the challenge of modelling uncertainty when inferring 3D geometry, the tradeoffs between various data sources, and the cost of including model structure.

We investigate the possibility of the high-energy particles with this new spectrum injected in pulsar wind nebulae (PWNe) from the terminate shock based on the study of multiwavelength emission from PWNe.} {The dynamics of a supernova remnant (SNR) and multiband nonthermal emission from the PWN inside the remnant are investigated using a dynamical model with electrons/positrons injected with the new spectrum.

No metastable de Sitter vacua in N=2 supergravity with only hypermultiplets

description: We study the stability of vacua with spontaneously broken supersymmetry in N=2 supergravity theories with only hypermultiplets. Focusing on the projection of the scalar mass matrix along the sGoldstino directions, we are able to derive a universal upper bound on the lowest mass eigenvalue. This bound only depends on the gravitino mass and the cosmological constant, but not on the details of the quaternionic manifold spanned by the scalar fields. Comparing with the Breitenlohner-Freedman bound shows that metastability requires the cosmological constant to be smaller than a certain negative critical value. Therefore, only AdS vacua with a sufficiently negative cosmological constant can be stable, while Minkowski and dS vacua necessarily have a tachyonic direction.

description: Further education (FE) has frequently been portrayed as «the Cinderella service» in relation to other phases; a «submerged space» operating below the surface and out of sight of mainstream educational policy in England. A contrasting view depicts a sector often considered a panacea for social concerns. FE is charged with supplying a skilled workforce and has been portrayed as a vehicle for enhancing economic development (DfEE 1998, Leitch 2006). Despite this it has repeatedly suffered funding cuts (Tickle 2014) alongside imposed political change. This research explores the stories of tutors and managers affected by managerial processes in English FE. The findings revealed the impact of corporatisation on leadership as well as on tutor and student agency and explored how professional collaboration enabled practitioners to challenge the prevailing systems-driven culture in ways which would help the sector step out of the shadows.

Its main objective is to comprehend the values, purposes and rationale that lie beneath teaching training programs. Therefore, the focal point of the present study is to examine the experiences that are often found in teaching practices. The methodology of this investigation follows an epistemological and interpretative perspective through the use of a biographical-narrative approach. In this regard, from the analysis of teachers’ accounts it is expected to first, reflect on their educational experiences, second, weigh the meaning behind their daily teaching practices and interactions with students, and finally, extend on their experiences as teaching program students. For this purpose, the accounts of two secondary school teachers are portrayed. The findings reveal the complexity of the pedagogical practice as a reflective profession which, in turn, triggers moral, affective and political repercussions (Arnaus, 1999).

description: Societies in Europe and around the world are facing an unprecedented ageing of the population. This situation raises policy questions regarding how to ensure the inclusion of older adults so that they can enjoy full human rights in all domains of life. Ageism compromises human flourishing and represents a social justice issue. A solution is connecting the need for lifelong learning with intergenerational programs (IGPs), which promote inclusion, active citizenship and personal development. This concept is only partially understood, both at the policy and practice levels. To address this issue, an Italy – United States collaboration was formed to test an empowerment-based model, called “Building a Community Legacy Together” (BCLT), that creates environments for co-learning between older people and youth. Through this case study we argue that to support projects of living for older adults, it is necessary to rethink the current policy framework, offering opportunities for personal and social growth.

Publisher: name: Encyclopaideia
Year: 2019
Subjects: Adult Education and Learning Policy Making; Social Cohesion; Equality of Access; Transnational Migrants; Language and Citizenship

description: The aim of the paper is to critically examine policy and practice in language education for adult migrants in the UK and Germany with the objective of interrogating the iteration of policy by national government through the perspective of pedagogic practice in two providers: a centre providing English to Speakers of Other Languages (ESOL) in the UK and another delivering Deutsch als Fremdsprache / DaF (German as a Foreign Language) in Germany. Data will include the providers’ curricula and policies; pedagogic resources; lesson observations; and interviews with teachers and managers of the provision, to discuss their views of language education policy and the articulation of policy within their organisation. The conclusions will provide a commentary on the extent to which language education provides opportunities for a critical approach to learning for migrants or whether it is fulfilling government agendas for integration and supporting mainstream economic activity by preparing learners for work.

Is it the Taking Part that Counts?  Access to Lifelong Learning Opportunities in Germany’s Regime of Dis/Ability
Creators: name: Schreiber-Barsch, Silke
Publisher: name: Encyclopaideia
Year: 2019
Subjects: Adult Education; Inclusion; Dis/Ability; Spatial Theory; Citizenship

description: This paper reveals why the issue of transforming the system of lifelong learning towards an ‘inclusive education system at all levels and lifelong learning’ (United Nations, 2006, p. 16), due to national ratifications of the UN Convention on the Rights of Persons with Disabilities (2006), cuts right to the core of democratic societies and national policy agendas. Following the socio-spatial works by Löw (2001; 2008), the example of the German lifelong learning arena serves to illustrate the benefit of spatial theory in the adult education discourse. Empirical findings of a qualitative research design allow insights into how access to a place of learning is interpreted and organised by adult education professionals. It opens up an understanding of who gains access to public adult education institutions and, imperatively, why access is not merely a pedagogical issue, but a negotiation of citizenship and politics and is, thus, of a genuine political nature.

Social Practices or Functional Skills? Rehabilitation or Rights? An Analysis of Scottish Prison Learning Contracts
Creators: name: Galloway, Sarah
Publisher: name: Encyclopaideia
Year: 2019
Subjects: Prison Education; Adult Education; Social Practice; Literacies Learning; Desistance; Marketisation

description: This paper critically examines some of the research arising from prison contexts internationally, questioning the notion that adult learning might serve the purpose of rehabilitation or encouraging desistance from crime. These discussions are utilised to inform a strategy for conducting a high-level documentary analysis of historical and current commercial contracts, held between colleges of further education and the Scottish Prison Service, for the delivery of prisoner education in Scotland. Here I suggest that leadership from the further education sector and the prison service in Scotland have made use of favourable national adult learning policies, co-creating commercial contracts that might take forward a social practice approach to prison learning. However, I also question the educational basis for both the commercial contracting of adult learning and the notion that adult learning should encourage desistance from criminality.

description: The development of fast and accurate methods of photometric redshift estimation is a vital step towards being able to fully utilize the data of next-generation surveys within precision cosmology. In this paper we apply a specific approach to spectral connectivity analysis (SCA; Lee & Wasserman 2009) called diffusion map. SCA is a class of non-linear techniques for transforming observed data (e.g., photometric colours for each galaxy, where the data lie on a complex subset of p-dimensional space) to a simpler, more natural coordinate system wherein we apply regression to make redshift predictions. As SCA relies upon eigen-decomposition, our training set size is limited to ~ 10,000 galaxies; we use the Nystrom extension to quickly estimate diffusion coordinates for objects not in the training set. We apply our method to 350,738 SDSS main sample galaxies, 29,816 SDSS luminous red galaxies, and 5,223 galaxies from DEEP2 with CFHTLS ugriz photometry. For all three datasets, we achieve prediction accuracies on par with previous analyses, and find that use of the Nystrom extension leads to a negligible loss of prediction accuracy relative to that achieved with the training sets. As in some previous analyses (e.g., Collister & Lahav 2004, Ball et al. 2008), we observe that our predictions are generally too high (low) in the low (high) redshift regimes. We demonstrate that this is a manifestation of attenuation bias, wherein measurement error (i.e., uncertainty in diffusion coordinates due to uncertainty in the measured fluxes/magnitudes) reduces the slope of the best-fit regression line. Mitigation of this bias is necessary if we are to use photometric redshift estimates produced by computationally efficient empirical methods in precision cosmology.

Diffuse Galactic emission spectrum between 0.5 and 8.0 MeV

description: The last measurement of the diffuse emission spectrum of the Milky Way in the megaelectronvolt (MeV) photon energy range was performed by CGRO/COMPTEL more than 20 years ago. We report a new analysis with the spectrometer SPI aboard INTEGRAL in the band 0.5-8.0 MeV, finally superseding the signal-to-noise ratio of the historic observations. This is possible thanks to an elaborate instrumental background model and careful considerations of the selected data, which are strongly affected by solar activity. We base our analysis on energy-dependent spatial template fitting in a region of $Δl \times Δb = 95^\circ \times 95^\circ$ around the Galactic centre. Our flux estimates are consistent with COMPTEL measurements and show no `MeV bump'. The spectrum follows a power-law shape with index $-1.39 \pm 0.09_{\rm stat} \pm 0.10_{\rm syst}$ and an integrated flux of $(5.7 \pm 0.8_{\rm stat} \pm 1.7_{\rm syst}) \times 10^{-8}\,\mathrm{erg\,cm^{-2}\,s^{-1}}$ between 0.5 and 8.0 MeV. We find that cosmic-ray electrons and propagation models consistent with the latest Fermi/LAT, Voyager 1, and AMS-02 data are broadly in agreement with the inferred inverse Compton spectral shape. However, a mismatch of a factor of 2-3 in normalisation with respect to baseline expectations may point to enhanced target photon densities and/or electron source spectra in the inner Galaxy, slightly modified diffusion properties, or the presence of an unresolved population of MeV $γ$-ray sources.

description: We report on ground-based FTIR observations being performed within the framework of the ESA-NIVR-KNMI project 2907 entitled "OMI validation by ground based remote sensing: ozone columns and atmospheric profiles" for the purpose of OMI data validation. FTIR observations were performed during the time frames August-October 2005, June-October 2006 and March-October 2007, mostly under cloud free and clear sky conditions and in some days from early morning to sunset covering the full range of solar zenith angles possible. Ozone column and ozone profile data were obtained for the year 2005 using spectral modeling of the ozone spectral band profile near 9.6 microns with the MODTRAN3 band model based on the HITRAN-96 molecular absorption database. The total ozone column values retrieved from FTIR observations are biased low with respect to OMI-DOAS data by 8-10 DU on average, where they have a relatively small standard error of about 2%. FTIR observations for the year 2006 were simulated by MODTRAN4 modeling. For the retrieval of ozone column estimates and particularly ozone profiles from our FTIR observations, we used the following data sources to as input files to construct the (a priori) information for the model: satellite Aqua-AIRS water vapor and temperature profiles; Aura-MLS stratospheric ozone profiles (version 1.5), TEMIS climatological ozone profiles and the simultaneously performed surface ozone measurements. Ozone total columns obtained from our FTIR observations for year 2006 with MODTRAN4 modeling are matching rather well with OMI-TOMS and OMI-DOAS data where standard errors are 0.68% and 1.11%, respectively. AURA-MLS data which have become available in 2007 allow us to retrieve tropospheric ozone profiles.

Displacement and dispersion effects in vertical eccentric annulus flows
Creators: name: Zhang, Ruizi
Publisher: name: University of British Columbia
Year: 2024

description: The oil and gas industry, while offering numerous benefits, grapples with environmental and sustainability challenges such as uncontrolled gas emissions, greenhouse gas contributions, ecological damage, and risks to groundwater. This thesis focuses on a pivotal industry operation: primary cementing. It is a process aimed at mechanical stability and hydraulic isolation, achieved by placing cement slurries in the annular space between a steel casing and wellbore. Failing to meet these objectives could potentially have consequences in terms of wellbore integrity. Complications arise from the eccentricity of the annular regions and the complexities of the involved fluids. The main emphasis of this thesis lies in understanding dispersion behavior and performing classifications for displacement flows in vertical eccentric annuli. This type of flow underlies the primary cementing process which is fundamental to preventing leakage. We firstly make a comprehensive comparison between the 2D gap-averaged model (2DGA) and a 3D model. The cases show both the successes and failures of the Hele-Shaw approach. Acknowledging the main limitation of 2DGA model, we then re-derive it starting from the reduced shear flow equations by applying a different assumption regarding the distribution of fluids across the annular gap. We find significant improvement of the dispersive 2DGA (D2DGA) model in capturing the gap-scale dispersion. A series of experiments has been conducted using our lab-built setup. We start from the displacement flows of Newtonian fluids in a vertical annulus, studied from both experimental and computational aspects. The models have been validated and are found to be effective and robust in predicting different flow behaviours. We develop a set of criteria for flow classifications, applicable for both concentric and eccentric annuli. The eccentricity and buoyancy number are found to be the dominant parameters affecting the front behaviour as well as the displacement efficiency. Finally we extend our study to shear-thinning fluids, employing a combination of experimental and computational methods. The classification criteria also prove effective in discerning various flow types, aligning with the results from the Newtonian study to a degree. Additional information due to extreme viscosity ratios is provided, along with study of some intriguing shear-thinning effects.
