description: It is well known that, under standard assumptions, initial value problems for fractional ordinary differential equations involving Caputo-type derivatives are well posed in the sense that a unique solution exists and that this solution continuously depends on the given function, the initial value and the order of the derivative. Here we extend this well-posedness concept to the extent that we also allow the location of the starting point of the differential operator to be changed, and we prove that the solution depends on this parameter in a continuous way too if the usual assumptions are satisfied. Similarly, the solution to the corresponding terminal value problems depends on the location of the starting point and of the terminal point in a continuous way too.

description: Optically excited electron-hole pairs, driven by a strong terahertz (THz) field, create high-sidebands in the optical spectrum. The sideband spectrum exhibits a 'plateau' up to a cutoff of 3.17Up, where Up is the ponderomotive energy. This cutoff is determined, semi-classically, from the maximum kinetic energy an electron-hole pair can gain from the THz field along a closed trajectory. A full quantum treatment reveals a second, classically forbidden, plateau with a cutoff of 8Up, the maximum kinetic energy an electron-hole pair can gain from the THz field along an open trajectory. The second plateau appears because a spatially separated electron and hole can still recombine if the classical excursion is within the coherence length of the electron-hole wavefunction or, equivalently, the coherence time is longer than the excursion time (half the THz field period). This effect broadens the range of materials and excitation conditions where high-sideband generations can occur, thereby providing a wealth of novel systems for ultrafast electro-optical applications.

Elucidation and derivatisation of bisindole biosynthesis pathways
Creators: name: Lai, Hung En
Publisher: name: Imperial College London
Year: 2019

description: Bisindole natural products encompass the well-studied indolocarbazoles, such as rebeccamycin and staurosporine, among other minor classes including indolotryptolines and bisindolylpyrroles. Bisindole biosynthesis starts from L-tryptophan and forms highly aromatic bisindole scaffolds in a series of biosynthetic steps, which are catalysed by various core scaffold formation and tailoring enzymes that work in tandem to shuttle highly labile bisindole intermediates to the cognate biosynthetic routes. Due to the demonstrated potent biological activities of bisindoles against disease-relevant clinical targets, new bisindoles and their synthetic analogues could yield promising drug candidates with improved activities. This thesis sets out to implement synthetic biology approaches to discover and diversify bisindoles via a two-pronged strategy – (1) by combinatorial assembly of bisindole biosynthesis pathway variants, or in combination with synthetic chemistry to further diversify the chemical scaffolds, and (2) by genome mining of new bisindole biosynthetic gene clusters (BGCs) using existing bioinformatic tools and experimental validation of the BGCs via heterologous expression. The first aim was achieved by derivatising the antimicrobial bisindole violacein scaffold by precursor-directed biosynthesis, in vivo halogenation and semi-synthesis of cross-coupling violacein derivatives based on a brominated scaffold. The violacein biosynthesis pathway was also refactored and heterologously expressed in Escherichia coli as a proof-of-concept demonstration of rapid pathway assembly using the EcoFlex Golden Gate toolkit with user-customisable genetic parts. The second aim was achieved by genome mining for the uniquely conserved chromopyrrolic acid synthase (CPAS) enzyme homologues, which led to the identification of two new bisindole BGCs (acf and nos). Heterologous expression of these BGCs in Streptomyces coelicolor resulted in the discovery of new bisindoles including arcyriaflavin F. Further investigations into new bisindole BGCs with unusual enzymes, in combination with semi-synthetic and synthetic biology approaches, will likely lead to the discovery of novel bisindoles with unprecedented scaffolds and biological activities.

Wavelet estimation for point processes
Creators: name: Taleb, Youssef
Publisher: name: Imperial College London
Year: 2019

description: Wavelet theory constitutes one of the most significant mathematical advances for signal processing, and thus presents a great interest in point process analysis. For instance, numerous approaches have been explored to estimate the first-order intensity of a point process with wavelets. In this thesis, we intend to consolidate existing results in wavelet-based linear estimation and investigate further applications of wavelets on point processes in the context of multiresolution analysis. We initially take this wavelet-based approach to estimate the first and higher-order intensities of a point process in any finite dimension and under a continuous spatial setting. We perform a statistical study of wavelet linear estimators when the observed events are located in a hyperrectangle of R^d. It is notably shown that the linear estimator of the complete k-th order intensity is the product of k linear estimators of the first-order intensity. Such wavelet modelling also motivates the construction of a first-order multiresolution analysis, through the definition of properties at different scales, termed J-th level homogeneity and L-th level innovation. Likelihood ratio tests for these properties are provided and studied under Poisson processes and Haar wavelets. A key result is that the applicability of these tests is linked to the product of the number of realizations and the expectation measure of the process. This means that one can use the asymptotic distributions of the test statistics from a single point pattern if the expectation measure is itself sufficiently high. The hypothesis test for L-th level innovation is then used to design new data-driven thresholding strategies, each based on a different grouping of wavelet coefficients. Our thresholding methods are studied through extensive simulations and applied to NetFlow data to exhibit the differences between human and automated behaviour. Since wavelet estimation of Cox processes has received very little treatment to this day, we provide new developments in this topic essentially through the wavelet-based estimation of the pointwise probability density or mass function for the intensity field. The behaviour of this estimator is studied with example Cox process models for different wavelets and resolutions, followed by an application to firing patterns from virtual reality military training. We eventually extend the idea of J-th level homogeneity to Cox processes by re-defining it through the mean intensity field, which we then test with a method based on Hotelling’s t-squared statistic.

description: In the present work, we consider the problem of a system of few vortices $N \leq 5$ as it emerges from its experimental realization in the field of atomic Bose-Einstein condensates. Starting from the corresponding equations of motion, we use a two-pronged approach in order to reveal the configuration space of the system's preferred dynamical states. On the one hand, we use a Monte-Carlo method parametrizing the vortex "particles" by means of hyperspherical coordinates and identifying the minimal energy ground states thereof for $N=2, ..., 5$ and different vortex particle angular momenta. We then complement this picture with a dynamical systems analysis of the possible rigidly rotating states. The latter reveals all the supercritical and subcritical pitchfork, as well as saddle-center bifurcations that arise exposing the full wealth of the problem even at such low dimensional cases. By corroborating the results of the two methods, it becomes fairly transparent which branch the Monte-Carlo approach selects for different values of the angular momentum which is used as a bifurcation parameter.

description: In this paper, we use the Galaxy Zoo 2 dataset to study the behavior of bars in disk galaxies as a function of specific star formation rate (SSFR), and bulge prominence. Our sample consists of 13,295 disk galaxies, with an overall (strong) bar fraction of $23.6\pm 0.4\%$, of which 1,154 barred galaxies also have bar length measurements. These samples are the largest ever used to study the role of bars in galaxy evolution. We find that the likelihood of a galaxy hosting a bar is anti-correlated with SSFR, regardless of stellar mass or bulge prominence. We find that the trends of bar likelihood and bar length with bulge prominence are bimodal with SSFR. We interpret these observations using state-of-the-art simulations of bar evolution which include live halos and the effects of gas and star formation. We suggest our observed trends of bar likelihood with SSFR are driven by the gas fraction of the disks; a factor demonstrated to significantly retard both bar formation and evolution in models. We interpret the bimodal relationship between bulge prominence and bar properties as due to the complicated effects of classical bulges and central mass concentrations on bar evolution, and also to the growth of disky pseudobulges by bar evolution. These results represent empirical evidence for secular evolution driven by bars in disk galaxies. This work suggests that bars are not stagnant structures within disk galaxies, but are a critical evolutionary driver of their host galaxies in the local universe ($z<1$).

The Office Under the Parking Garage: Disability and Accommodations at the University of Chicago

description: Although the number of disabled students attending postsecondary institutions has increased in recent decades, the postsecondary graduation rate for disabled students is significantly lower than the graduation rate for their nondisabled peers. While research has identified certain obstacles that disabled students face in postsecondary education, this research has not focused on the experiences of disabled students attending elite institutions. Through the use of a qualitative content analysis of in-depth interviews with current and former undergraduates at the University of Chicago who have applied for accommodations, I identify various challenges these students face in receiving accommodations and having them honored. Additionally, I explore student-perceived peer, faculty, and administration attitudes towards accommodations, as well as the cultural aspects associated with elite institutions that hinder disabled students in pursuing their academic goals. The findings of this paper reveal a need for the University of Chicago’s Student Disability Services (SDS) to be allotted increased authority in order to enforce the implementation of both academic and housing related temporary and permanent accommodations, increased measures on behalf of the University’s administration to make the campus more physically accessible, and more training for students, faculty, and staff members at Student Disability Services regarding ableism, accommodations, and disability issues. These findings contribute to efforts to make postsecondary education more accessible for disabled students by identifying institutional barriers at elite universities.

Effects of temperature on microbial metabolic rates
Creators: name: Smith, Thomas
Publisher: name: Imperial College London
Year: 2019

description: Prokaryotes (bacteria and archaea) are globally ubiquitous micro-organisms which play fundamental roles in biogeochemical cycles and ecosystem functioning. Understanding how these microbes are affected by temperature is key to our understanding of how ecosystem processes will be affected by and respond to climate change. This includes understanding both how temperature directly affects the biological rates of prokaryotes through to how community composition may change with temperature and the impacts that these responses have on overall community functioning. Combining meta-analyses with experimental work and mathematical modelling, I assessed the direct impacts of temperature on microbial biological rates, with the aim of understanding how these effects translate to community and ecosystem level changes. I performed a meta-analysis of prokaryotic growth and metabolic rates, spanning the entire temperature spectrum of life on earth, revealing that the metabolic rates of mesophilic prokaryotes are likely to rise with climate warming. I used experimental methods to reveal the phenotypic diversity of temperature fitness in microbial communities, suggesting that species sorting rather than direct thermal adaptation may play a major role in how ecosystems respond to climate change. This work also revealed a disparity in phylogenetic groups associated with cooler and warmer temperatures as well as a divergence in their growth strategies, with warmer adapted taxa tending towards growth specialism rather than yield specialism. I also tested how microbial carbon use efficiency — the proportion of carbon uptake allocated to growth — varies with temperature. I found a unimodal temperature dependence of this trait, a departure from previous understanding. This work shows that changes in the composition and function of microbial communities with global change are likely to have a profound impact on ecosystem responses to warming. I propose that through species sorting processes, microbial communities are likely to shift to warmer adapted taxa with higher metabolic rates on average, which tend to be less carbon efficient in their growth. Ultimately, this may lead to increased carbon efflux versus sequestration by the microbial components of ecosystems with climate warming.
Global electricity sector decarbonization modelling

Publisher: name: Imperial College London
Year: 2019

description: As variable renewable energies are set to become a key energy source in electricity sector worldwide, there is concern on the impact of the intermittency of their output when penetration is high. This research aims to investigate possible pathways for future electricity sector decarbonization with a focus on renewable development. This research starts with assessing the global capacity and energy potential for wind and solar power technologies, with a consistent approach. Validation of the developed approaches shows high accuracy of the identified potential areas, and high correlation between the estimated capacity factor and observed output records. When temporal and spatial resolution in a model increases, conventional mathematical programming-based models are limited by computational resources in simulating large systems. To find out the best mix of climate-related energies in a country, this research proposes a novel mathematical models that incorporates objectives of minimizing cost, residual load variation and portfolio output variation. The results suggest that for almost every country, the proposed optimal mix can effectively minimize these objectives simultaneously, promoting the case that a high share of these renewables can be reachable. Finally this research assesses pathways for electricity sector decarbonization. A framework is developed for modelling the electricity systems at regional market scale. This framework mainly consist of an economic dispatch model and a capacity expansion model. It incorporates measures to improve the system flexibility such as storage systems, reserve services and interconnection. Four scenarios are defined in this research. The results show that considerable emissions reduction is present in a base reference scenario, resulting from high penetration of renewables worldwide. Other scenarios can further cut the emissions, using policy instruments such as higher carbon prices, renewable penetration targets and emissions caps. Moreover, nuclear and carbon capture technologies may further drive the annual emissions down to negative values by 2050.
Family Unification Program Vouchers at the Intersection of Housing and Child Welfare Service Delivery: A Chicago Case Study
Creators: name: Blume, Rachel
Publisher: name: University of Chicago
Year: 2021

description: The Family Unification Program (FUP) is a Housing and Urban Development (HUD) initiative implemented on the local level to provide housing vouchers for families and youth involved in the child welfare system. Chicago’s Family Unification Program (FUP) is one of the largest and longest standing in the country. This paper is a process evaluation of Chicago’s FUP that aims to understand: (1) How is the partnership between the Illinois Department of Children and Family Services (DCFS), the Chicago Housing Authority (CHA), and Housing Advocacy Program (HAP) structured? (2) How does the partnership between CHA and DCFS affect how FUP is implemented? and (3) How can aspects of this partnership be scaled-up in order to offer additional housing services to low-income families? Data from 15 semi-structured interviews with FUP key informants and experts reveal that successful FUP implementation is dependent on a strong partnership between DCFS, CHA, and HAP. While currently Chicago’s FUP leads the country in strong interagency collaboration, its mixed impacts reveal that interagency implementation challenges remain. Specifically, this study explores some of the key variables impending FUP’s success, including implementation challenges and barriers to entry for FUP clients. Overall, this research finds that FUP’s program model is a useful starting point for further scale-up opportunities for housing and child welfare. Given the overlap between housing instability and placement into out-of-home care, this paper demonstrates how housing vouchers are a useful tool for servicing vulnerable families and preventing them from entering out-of- home care. Ultimately, this paper argues for the expansion of FUP and other housing resources.

description: Migratory birds can utilize the geomagnetic field for orientation and navigation through a widely accepted radical-pair mechanism. Although many theoretical works have been done the available experimental results have not been fully considered, especially, the temporary disorientation induced by the field which is increased by 30% of geomagnetic field and the disorientation of the very weak resonant field of $15nT$. In this paper, we consider the monotonicity of the singlet yield angular profile as the prerequisite of direction sensitivity, and find that for some optimal values of the hyperfine coupling parameters, that is the order of $10^{-7}\sim10^{-6}meV$, the experimental results available by far can be satisfied. We also investigate the effects of two decoherence environments and demonstrate that, in order to satisfy the available experimental results, the decoherence rate should be much lower than the recombination rate. Finally we investigate the effects of the fluctuating magnetic noises, and find that the vertical noise destroys the monotonicity of the profile completely, but the parallel noise preserves the monotonicity perfectly and even can enhance the direction sensitivity.

description: Honey bees are valuable bioindicators. As such, they hold a vast potential to help shed light on the extent and interdependencies of factors influencing the decline in the number of insects. However, to date this potential has not yet been fully leveraged, as the production of reliable data requires large-scale study designs, which are very labour intensive and therefore costly. A novel Artificial Intelligence (AI) based visual monitoring system could enable the partial automatization of data collection on activity, forager loss and impairment of the central nervous system. The possibility to extract features from image data could prospectively also allow an assessment of pollen intake and a differentiation of dead bees, drones and worker bees as well as other insects such as wasps or hornets. The technology was validated in different studies with regards to its scalability and its ability to extract motion and feature related information. The prospective possibilities were analyzed regarding their potential to enable advances both within ecotoxicological research and the monitoring of pollinator habitats.

The Bracket Geometry of Statistics
Creators: name: Barp, Alessandro Andrea
Publisher: name: Imperial College London
Year: 2020

description: In this thesis we build a geometric theory of Hamiltonian Monte Carlo, with an emphasis on symmetries and its bracket generalisations, construct the canonical geometry of smooth measures and Stein operators, and derive the complete recipe of measure-constraints preserving dynamics and diffusions on arbitrary manifolds. Specifically, we will explain the central role played by mechanics with symmetries to obtain efficient numerical integrators, and provide a general method to construct explicit integrators for HMC on geodesic orbit manifolds via symplectic reduction. Following ideas developed by Maxwell, Volterra, Poincaré, de Rham, Koszul, Dufour, Weinstein, and others, we will then show that any smooth distribution generates considerable geometric content, including ``musical" isomorphisms between multi-vector fields and twisted differential forms, and a boundary operator - the rotationnel, which, in particular, engenders the canonical Stein operator. We then introduce the ``bracket formalism" and its induced mechanics, a generalisation of Poisson mechanics and gradient flows that provides a general mechanism to associate unnormalised probability densities to flows depending on the score pointwise. Most importantly, we will characterise all measure-constraints preserving flows on arbitrary manifolds, showing the intimate relation between measure-preserving Nambu mechanics and closed twisted forms. Our results are canonical. As a special case we obtain the characterisation of measure-preserving bracket mechanical systems and measure-preserving diffusions, thus explaining and extending to manifolds the complete recipe of SGMCMC. We will discuss the geometry of Stein operators and extend the density approach by showing these are simply a reformulation of the exterior derivative on twisted forms satisfying Stokes' theorem. Combining the canonical Stein operator with brackets allows us to naturally recover the Riemannian and diffusion Stein operators as special cases. Finally, we shall introduce the minimum Stein discrepancy estimators, which provide a unifying perspective of parameter inference based on score matching, contrastive divergence, and minimum probability flow.

Baryon Stability on the Higgs Dissolution Edge : Threshold corrections and suppression of Baryon violation in the NMSGUT

description: Superheavy threshold corrections to the matching condition between matter Yukawa couplings of the effective Minimal Supersymmetric Standard Model (MSSM) and the New Minimal Supersymmetric (SO(10)) GUT(NMSGUT) provide a novel and generic mechanism for reducing the long standing and generically problematic operator dimension 5 Baryon decay rates. In suitable regions of the parameter space strong wave function renormalization of the effective MSSM Higgs doublets due to the large number of heavy fields can take the wave function renormalization of the MSSM Higgs field close to the dissolution value ($Z_{H,\overline{H}}=0$). Rescaling to canonical kinetic terms lowers the SO(10) Yukawas required to match the MSSM fermion data. Since the same Yukawas determine the dimension 5 B violation operator coefficients, the associated rates can be suppressed to levels compatible with current limits. Including these threshold effects also relaxes the constraint $ y_b-y_τ\simeq y_s-y_μ$ operative between $\textbf{10} -\textbf{120} $ plet generated tree level MSSM matter fermion Yukawas $y_f$. We exhibit accurate fits of the MSSM fermion mass-mixing data in terms of NMSGUT superpotential couplings and 5 independent soft Susy breaking parameters specified at $10^{16.25}\,$ GeV with the claimed suppression of Baryon decay rates. As before, our s-spectra are of the mini split supersymmetry type with large $|A_0|,μ,m_{H,\overline H} > 100\,\,$ TeV, light gauginos and normal s-hierarchy. Large $A_0,μ$ and soft masses allow significant deviation from the canonical GUT gaugino mass ratios and ensure vacuum safety. Even without optimization, prominent candidates for BSM discovery such as the muon magnetic anomaly, $b\rightarrow sγ$ and Lepto-genesis CP violation emerge in the preferred ball park.

The Calabi-Yau problem, null curves, and Bryant surfaces

description: In this paper we prove that every bordered Riemann surface M admits a complete proper null holomorphic embedding into a ball of the complex Euclidean $3$-space $\mathbb{C}^3$. The real part of such an embedding is a complete conformal minimal immersion $M\to \mathbb{R}^3$ with bounded image. For any such $M$ we also construct proper null holomorphic embeddings $M\to \mathbb{C}^3$ with a bounded coordinate function; these give rise to properly embedded null curves $M\to SL_2(\mathbb{C})$ and to properly immersed Bryant surfaces $M\to \mathbb{H}^3$ in the hyperbolic $3$-space. In particular, we give the first examples of proper Bryant surfaces with finite topology and of hyperbolic conformal type. The main novelty when compared to the existing results in the literature is that we work with a fixed conformal structure on $M$. This is accomplished by introducing a conceptually new method based on complex analytic techniques. One of our main tools is an approximate solution to the Riemann-Hilbert boundary value problem for null curves in $\mathbb{C}^3$.

description: It is shown that any homogeneous and isotropic universe, independently of its spatial topology and matter content, allows for the presence of a conformal stealth, i.e. a nontrivial conformally invariant scalar field with vanishing energy-momentum tensor, which evolves along with the universe without causing even the smallest backreaction. Surprisingly, this gravitationally invisible universal witness is inhomogeneous with zero consequences for the underlying cosmology. Additionally, it is shown that these results are not exclusive of a four-dimensional universe by generalizing them to higher dimensions.

Can the degeneracies in the gravity sector be broken?

description: It has been long known that by appropriately modifying gravity one can always reproduce the expansion history of any dark energy model, e.g. the $Λ$CDM. This degeneracy cannot be broken with geometric probes like the Type Ia supernovae, the cosmic microwave background or the baryon acoustic oscillations since they are based on the measurement of distances and scales and therefore require the expansion history $H(z)$, so one may only hope to break this degeneracy by using dynamic probes like the growth rate data that track the matter density perturbations. We demonstrate that breaking this degeneracy is not currently possible by explicitly constructing $f(R)$, $f(G)$ and $f(T)$ theories that mimic exactly the $Λ$CDM model at the background level and confronting them against the latest observational cosmological data. We also determine the necessary improvement in the growth rate data in order to discriminate these theories from $Λ$CDM. We found that at least a threefold improvement is necessary, something which will be possible with a survey like Euclid.

Probing the Higgs Portal at the LHC Through Resonant di-Higgs Production
Creators: name: No, Jose M.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We investigate resonant di-Higgs production as a means of probing extended scalar sectors that include a 125 GeV Standard Model-like Higgs boson. For concreteness, we consider a gauge singlet Higgs portal scenario leading to two mixed doublet-singlet states, h_1,2. For m_h_2 > 2 m_h_1, the resonant di-Higgs production process p p -> h_2 -> h_1 h_1 will lead to final states associated with the decaying pair of Standard Model-like Higgs scalars. We focus on h_2 production via gluon fusion and on the b b tau^+ tau^- final state. We find that discovery of the h_2 at the LHC may be achieved with ~ 100 fb^-1 of integrated luminosity for benchmark parameter choices relevant to cosmology. Our analysis directly maps onto the decoupling limits of the Next-to-Minimal Supersymmetric Standard Model (NMSSM) and more generically onto extensions of the Standard Model Higgs sector in which a heavy scalar produced through gluon fusion decays to a pair of Standard Model-like Higgs bosons.

description: To begin to address an international gap in scholarship around the sister marches of the 2017 Women’s March, this master’s paper performed content analysis on a corpus of protest posters from three countries: the United States, England and Poland.  Concerns, characters, symbols and text from each march were compared to one other and to previous Women’s March research.  This study revealed that all three sister marches framed at least half of their posters toward an American context but also negotiated their content with a local identity.  Warning: This paper contains uncensored language and images of protest.
