description: Global probabilistic inversion within the latent space learned by a Generative Adversarial Network (GAN) has been recently demonstrated. Compared to inversion on the original model space, using the latent space of a trained GAN can offer the following benefits: (1) the generated model proposals are geostatistically consistent with the prescribed prior training image (TI), and (2) the parameter space is reduced by orders of magnitude compared to the original model space. Nevertheless, exploring the learned latent space by state-of-the-art Markov chain Monte Carlo (MCMC) methods may still require a large computational effort. As an alternative, parameters in this latent space could possibly be optimized with much less computationally expensive gradient-based methods. We show that due to the typically highly nonlinear relationship between the latent space and the associated output space of a GAN, gradient-based deterministic inversion may fail even when considering a linear forward physical model. We tested two deterministic inversion approaches: a quasi-Newton gradient descent using the Adam algorithm and a Gauss-Newton (GN) method that makes use of the Jacobian matrix calculated by finite-differencing. For a channelized binary TI and a synthetic linear crosshole ground penetrating radar (GPR) tomography problem involving 576 measurements with low noise, we observe that when allowing for a total of 10,000 iterations only 13% of the gradient descent trials locate a solution that has the required data misfit. The tested GN inversion was unable to recover a solution with the appropriate data misfit. Our results suggest that deterministic inversion performance strongly depends on the inversion approach, starting model, true reference model, number of iterations and noise realization. In contrast, computationally-expensive probabilistic global optimization always finds an appropriate solution.

description: Measurement of carbon dioxide (CO2), oxygen (O2), and nitrogen (N2) concentration in modified atmosphere packaging (MAP) food is critical to be carried out by the food industry. A slight variation in concentrations of CO2, O2, and N2 in food packaging may have a significant impact on product quality and safety for human health. Accurate and reliable measurement of CO2, O2, and N2 concentrations in food packaging is crucial, and it can only be achieved by calibrating the gas analyzer. This study aimed to develop gas mixtures for the calibration of CO2, O2, and N2 gas analyzers at a typical concentration range of modified atmosphere packaging. The calibration gas mixtures were prepared gravimetrically by following ISO 6142. The concentration ranges of CO2, O2, and N2 for calibration gas mixtures were set at 9-19% mol/mol, 1-5% mol/mol, and 74-88%mol/mol, respectively. Each parent gas was identified for its impurities using gas chromatography with a pulsed discharge helium ionization detector (GC-PDHID). The compositions of CO2, O2, and N2 in the mixtures were verified by evaluating the internal consistency within the prepared gas mixtures using gas chromatography with a thermal conductivity detector (GC-TCD). The short term stability of the prepared gas mixtures was evaluated using an equal division method. The result showed that good internal consistency was achieved between the gravimetrical and GC’s verification values, having linear regression coefficient (R2 ) ≥ 0.999. The t-test result has shown that CO2 has better short term stability than O2 and N2. In conclusion, the developed calibration gas mixtures at a typical concentration range of modified atmosphere packaging have shown satisfying results for CO2 component. However, further evaluation is still required to minimize the instability of O2 and N2 components.
Catalysis in flow: Chemoenzymatic Dynamic Kinetic Resolution of chiral amines
Creators: name: Takle, Matthew
Publisher: name: Imperial College London
Year: 2023

description: An investigation of the Chemoenzymatic Dynamic Kinetic Resolution of racemic amines is reported using a dual transition metal-enzyme catalysed process, as a methodology for the synthesis of chiral amines. This work is comprised of 4 sections: a literature review of the existing synthetic methodologies for the synthesis of chiral amines; the discovery and development of a Flash Thermal Racemisation (FTR) procedure; the interrogation of enzymatic kinetic resolution in continuous flow; and finally, implementation and analysis of the first demonstration of a compartmentalised FTR-CE-DKR under flow conditions. Previously, Chemoenzymatic Dynamic Kinetic Resolution has been reported to be an effective approach for the resolution of chiral amines but was greatly limited by its inability to be conducted on an industrially relevant scale. The key challenge faced by the process is the lack of compatibility of the two tandem catalysts required for the racemisation and enzyme-catalysed acylation steps. Despite much effort, this process has been plagued by the compromises made, which have led to the use of sub-optimal reaction conditions for each individual step. Deactivation of the transition metal or enzyme catalysts has also been a problem leading to overall limited productivity and lack of scalability, rendering the processes of limited application in a commercial setting. The development of the FTR-CE-DKR methodology reported here has demonstrated how continuous flow can be applied to effectively compartmentalise each step of the processes, thus allowing optimal conditions to be applied to each step. This has enabled proof-of-concept studies to be carried out that demonstrate the ability of this approach to greatly increase the productivity of the process to synthesise chiral amines in a scalable manner.

Using a simple approximate theory we show that the probability p_n(t_1,t_2) that ϕ( _x_ ,t) [for a given space point _x_ ] changes sign n times between t_1 and t_2 has the asymptotic form p_n(t_1,t_2) \sim [\ln(t_2/t_1)]^n(t_1/t_2)^{-θ}. The exponent θhas predicted values 0.1203, 0.1862, 0.2358 in dimensions d=1,2,3, in remarkably good agreement with simulation results.

description: Context. In a recent statistical study of sunspots in 79 active regions, the vertical magnetic field component $B_\text{ver}$ averaged along the umbral boundary is found to be independent of sunspot size. The authors of that study conclude that the absolute value of $B_\text{ver}$ at the umbral boundary is the same for all spots. Aims. We investigate the temporal evolution of $B_\text{ver}$ averaged along the umbral boundary of one long-lived sunspot during its stable phase. Methods. We analysed data from the HMI instrument on-board SDO. Contours of continuum intensity at $I_\text{c}=0.5I_\text{qs}$, whereby $I_\text{qs}$ refers to the average over the quiet sun areas, are used to extract the magnetic field along the umbral boundary. Projection effects due to different formation heights of the Fe I 617.3 nm line and continuum are taken into account. To avoid limb artefacts, the spot is only analysed for heliocentric angles smaller than $60^{\circ}$. Results. During the first disc passage, NOAA AR 11591, $B_\text{ver}$ remains constant at 1693 G with a root-mean-square deviation of 15 G, whereas the magnetic field strength varies substantially (mean 2171 G, rms of 48 G) and shows a long term variation. Compensating for formation height has little influence on the mean value along each contour, but reduces the variations along the contour when away from disc centre, yielding a better match between the contours of $B_\text{ver}=1693$ G and $I_\text{c}=0.5I_\text{qs}$. Conclusions. During the disc passage of a stable sunspot, its umbral boundary can equivalently be defined by using the continuum intensity $I_\text{c}$ or the vertical magnetic field component $B_\text{ver}$. Contours of fixed magnetic field strength fail to outline the umbral boundary.

description: At any metal-carbon nanotube interface there is charge transfer and the induced interfacial field determines the position of the carbon nanotube band structure relative to the metal Fermi-level. In the case of a single-wall carbon nanotube (SWNT) supported on a gold substrate, we show that the charge transfers induce a local electrostatic potential perturbation which gives rise to the observed Fermi-level shift in scanning tunneling spectroscopy (STS) measurements. We also discuss the relevance of this study to recent experiments on carbon nanotube transistors and argue that the Fermi-level alignment will be different for carbon nanotube transistors with low resistance and high resistance contacts.

description: The Diversity at Mason series has been produced by the university's Diversity Research Group, which consists of an interdisciplinary group of faculty, administrators, and students who have been meeting once a semester since Spring 2004. The group has come together not out of any formal directive, but from a shared interest in the topic. And the topic? Each meeting begins with the same reminder: George Mason is a highly diverse institution, and it is diverse in ways that are fluid and multidimensional. Our students represent an extraordinary diversity of geographic origin, religion, age, and disability; they are immigrants and the children of immigrants, refugees and the children of refugees, veterans of American military service and the children of those in the military; they represent traditional American race and ethnic categories as well as those forging new understandings of sexuality and gender. The Diversity Research Group has been founded on the conviction that the breadth of our student diversity merits study. What is the educational impact of such diversity? What does diversity mean in this context? How is this diversity understood by our students, faculty, and staff? Like the other volumes in the Diversity at Mason series, this fifth issue shows us the complexity beneath questions.

The formalism for the unique first forbidden transitions has been developed, and it is shown that they can alter the two-electron energy spectrum. Yet, their effect is too small to screen the detection of exotic neutrinoless double beta decays, which are candidates for testing the physics beyond the standard model.

description: Generating nearly $10 billion in revenue during the 2012 season, the National Football League (NFL) has been shown to be, by data, to be by far the most popular and profitable professional sports league in the United States of America (“Why Football Is Still A Money Machine,” 2013). Dominating attention both during its season, and even during its offseason, fans ingest material around the clock from the league and its teams. The purpose of this thesis is to explore why consumers follow official NFL team Twitter accounts; what keeps them engaged with those accounts; and what types of content create positive long-term relationships. One of Twitter’s operational functions from a sports-level is producing stories, intensifying and spreading this content and information available in a public setting, and in turn, creating new ways of thinking about the interaction between sport and digital media by organizations, athletes, journalists, publicists, and fans among others (Hutchins, 2011). A quantitative methodology was used to identify fan motivators for following an official NFL team’s Twitter account and also finding reasoning behind why certain content tends to be more engaging. Through regression analysis, content from eight NFL teams’ official Twitter accounts was gathered over a two-week period. Twitter content was analyzed to identify fan engagement based on specific categories compared against an average number of “retweets” to determine which fans were most motivated to engage with both instantly and long-term.

description: In this letter, we investigate the effect of orbital angular momentum (OAM) on elastic photon-photon scattering in vacuum for the first time. We define exact solutions to the vacuum electro-magnetic wave equation which carry OAM. Using those, the expected coupling between three initialwaves is derived in the framework of an effective field theory based on the Euler-Heisenberg La-grangian and shows that OAM adds a signature to the generated photons thereby greatly improvingthe signal-to-noise ratio. This forms the basis for a proposed high-power laser experiment utilizingquantum optics techniques to filter the generated photons based on their OAM state

title: Relationships among Escherichia coli (E. coli), Total Suspended Solids and Flow for Three Northern Virginia Subwatersheds: Rabbit Branch, Upper Accotink Creek, and Daniels Run
Creators: name: Washington, Marissa
Publisher: name: George Mason University
Year: 2013

description: This project was designed and completed to satisfy the requirements for the M.S. Program in Environmental Science and Policy at George Mason University. Three sites located in Fairfax, Virginia residential areas were chosen to monitor Escherichia coli concentrations between May 18th and July 19th, 2013 and to examine the relationship of E. coli to stream flow, total suspended solids (TSS) and impervious cover. Each site was visited a total of 9 times during the study period. Analysis of data from these sites indicated that they are not meeting the Virginia Department of Environmental Quality (VDEQ) standard of 235 CFU/100 mL for E. coli in recreation streams. The range for E. coli over all three sites was 78 - 19,100 CFU/100 mL. There were also nine samples in which the levels were above the range of the test procedure (>20,000 CFU). This study also suggested that E. coli may respond to increased impervious cover, TSS and rainfall; however, due to a high degree of variability most of the relationships were not significant. Visual examination of the watersheds indicate that there are multiple potential upstream non-point sources including human and animal activity that could contribute to elevated E. coli levels. Because these sites are in violation of state water quality standards, it is imperative that the County and City Storm Water Planning Divisions further investigate and devise plans to fulfill the purpose of the Clean Water Act. Two of the three sites, Daniels Run and Rabbit Branch, could benefit from projects that have been proposed.

We then provide a generalization given by Barbara of the four-distance problem to regular polygons of unit side, in which a negative answer is almost always obtained.

description: The length of the geodesic between two data points along a Riemannian manifold, induced by a deep generative model, yields a principled measure of similarity. Current approaches are limited to low-dimensional latent spaces, due to the computational complexity of solving a non-convex optimisation problem. We propose finding shortest paths in a finite graph of samples from the aggregate approximate posterior, that can be solved exactly, at greatly reduced runtime, and without a notable loss in quality. Our approach, therefore, is hence applicable to high-dimensional problems, e.g., in the visual domain. We validate our approach empirically on a series of experiments using variational autoencoders applied to image data, including the Chair, FashionMNIST, and human movement data sets.

description: We investigate the paramagnetic-metal-to-antiferromagnetic-metal and antiferromagnetic-metal-to- antiferromagnetic-insulator transitions using a slave-boson mean-field theory. To this effect, we discuss the ground state of the half-filled Hubbard model as a function of t'/t and correlation strength U, where t and t' are the hopping amplitudes between nearest and next-nearest neighbors, respectively. The metal-insulator transition at a critical U_{MIT} is of second order for small levels of magnetic frustration, t'/t<0.06, and of first order for large ones, t'/t>0.06. The insulator is always antiferromagnetically ordered, while the metal exhibits a second-order transition from a paramagnetic to an antiferromagnetic state up to t'/t=0.14, as U is increased. We also contrast these findings with what we obtain in Hartree-Fock approximation.

description: First identified in the Rift Valley of Kenya, Rift Valley Fever Virus (RVFV) is a mosquito-borne zoonotic disease that can cause severe illness in humans and livestock. RVFV outbreaks can have remarkably devastating effects on livestock, in which RVFV causes spontaneous abortion in almost 100% of pregnant ruminants, referred to as an “abortion storm,” and a high mortality in young animals. These outbreaks can become a major burden for countries in which RVFV is endemic. Humans can also become infected with RVFV through a bite from an infected mosquito, which in many cases causes an acute febrile illness with symptoms including chills, malaise, dizziness, fever, and headache. In a small percentage of cases, the disease progresses to severe symptoms including blindness, hepatitis, encephalitis, and hemorrhagic fever. With the increased risk of spread, competent species in many areas of the world and the ease of international trade and travel, RVFV is considered an overlap select agent by the Centers of Disease Control and Prevention and the U.S. Department of Agriculture. There are currently no approved vaccines or therapeutics available to the public in order to combat RVFV infection. Current research has focused more on host factors that aid in viral replication, unveiling a new collection of targets for treatments. Signal transducer and activator of transcription (STAT) proteins are a family of transcription factors that regulate many aspects of the host cell, such as immunity, cell growth, survival, and proliferation. The JAK-STAT protein cascade is initiated when a receptor receives signals from external factors, such as cytokines and growth factors, which in turn activate receptor-associated tyrosine kinases. Our research shows that both STAT1 and STAT3 are phosphorylated on their conserved tyrosine residue following RVFV infection. These phosphorylation events are dependent on the viral protein NSs, as the MP12-ΔNSs virus, which has a complete deletion of the viral protein NSs, does not induce STAT1 and STAT3 phosphorylation. Our data also indicates that two specific mutations in NSs impair STAT3 tyrosine phosphorylation. Treatment of cells with a STAT3 small molecular inhibitor, Stattic, reduces MP12 viral titers at 8, 16, and 24 hours post infection. Finally, STAT3 -/- MEFs are more susceptible to RVFV induced cell death than WT MEFs, indicating that STAT3 functions as a pro-survival factor.

description: An open source software package for modelling thermal neutron transport is presented. The code facilitates Monte Carlo-based transport simulations and focuses in the initial release on interactions in both mosaic single crystals as well as polycrystalline materials and powders. Both coherent elastic (Bragg diffraction) and incoherent or inelastic (phonon) scattering are modelled, using basic parameters of the crystal unit cell as input. Included is a data library of validated crystal definitions, standalone tools and interfaces for C++, C and Python programming languages. Interfaces for two popular simulation packages, Geant4 and McStas, are provided, enabling highly realistic simulations of typical components at neutron scattering instruments, including beam filters, monochromators, analysers, samples and detectors. All interfaces are presented in detail, along with the end-user configuration procedure which is deliberately kept user-friendly and consistent across all interfaces. An overview of the relevant neutron scattering theory is provided, and the physics modelling capabilities of the software are discussed. Particular attention is given here to the ability to load crystal structures and form factors from various sources of input, and the results are benchmarked and validated against experimental data and existing crystallographic software. Good agreements are observed.
Super Resolution Microscopy to investigate epigenetic mechanisms driving platinum resistance in ovarian High Grade Serous Carcinoma
Creators: name: Lim, Mi Qi
Publisher: name: Imperial College London
Year: 2023

description: The high mortality rate of ovarian High Grade Serous Carcinoma (HGSC) partly results from frequent relapses with platinum-resistant disease, and accumulating evidence indicate the importance of epigenetic modifications, which influence higher order chromatin structure to regulate gene expression, driving this resistance. Currently, this structural information is typically inferred through bulk biochemical assays. Conversely, single molecule localisation microscopy (SMLM) methods like stochastic optical reconstruction microscopy (STORM) can directly probe these structures with single cell resolution, but most implementations are expensive and low-throughput. This thesis presents work towards developing a high-throughput SMLM assay to investigate epigenetic mechanisms driving carboplatin resistance in HGSC using easySTORM implemented on a novel low-cost and open-source microscopy platform (‘openFrame’). Sample preparation protocols and imaging parameters were optimised, during which nuclear pore complexes in U2OS-Nup96-SNAP cells were imaged to serve as reference structures for calibration. Subsequently, different SMLM cluster analysis pipelines were compared, as most pipelines are computationally intensive and require optimising user-selected parameters. A novel multi-component pair-correlation function fitting algorithm yielded similar results to established methods (e.g., DBSCAN) without requiring user-set parameters, and could analyse SMLM data from 100 nuclei in 40 minutes with parallel processing on 12-core high-performance computing (HPC) 128 GB RAM nodes. Physiologically relevant carboplatin-treatment models of HGSC were also studied to provide the biological basis for subsequent assays. Preliminary results indicate diverse early transcriptomic changes and increased accessibility of AP-1 binding sites across primary and established cell lines following treatment, suggesting an epigenetic role in resistance. Carboplatin-induced changes in chromatin structure of HGSC cells were investigated with automated multiwell plate imaging on the openFrame-based easySTORM platform. Preliminary results suggest a relative decompaction of chromatin in resistant cells, potentially correlating with a more stem-like phenotype. Overall, this work demonstrates the potential of this platform as a practical assay for investigating changes in chromatin structure.

description: Hunting is one of the most critical drivers of animal population decline. Despite its significance, wild meat consumption in Amazonian cities is poorly understood. In Iquitos, the largest urban center of the Peruvian Amazon, there is access to many different animal proteins, but people are still consuming a great deal of wild meat. To create more effective conservation strategies for highly consumed species, accurate estimates of wild meat consumption are needed. By systematically sampling the entire city and interviewing heads of households, this dissertation answers the question: How much wild meat are people eating, and what is driving their consumption?

description: We demonstrate a breakthrough in the capabilities of robust, broad-parameter space searches for continuous gravitational waves. With a large scale search for continuous gravitational waves on the O1 LIGO data, we prove that our Falcon search achieves the sensitivity improvements expected from the use of a long coherence length, while maintaining the computational expense within manageable bounds. On this data we set the most constraining upper limits in the gravitational wave amplitude in the band 100-200 Hz. We provide full outlier lists and upper limits near 0-spindown band suitable for analysis of signals with small spindown such as boson condensates around black holes.

description: The derivation of the Eliashberg -- type equations for a superconductor with strong correlations and electron--phonon interaction has been presented. The proper account of short range Coulomb interactions results in a strongly anisotropic equations. Possible symmetries of the order parameter include s, p and d wave. We found the carrier concentration dependence of the coupling constants corresponding to these symmetries. At low hole doping the d-wave component is the largest one.

description: Diterpenoid alkaloids are compounds found in plants that have been studied for their potential therapeutic effects. One such compound is karakoline, which has been shown to exhibit relaxant activity in various systems. Studies have found that karakoline can exert relaxant effects on smooth muscle, including in the gastrointestinal tract, respiratory system, and blood vessels. This may be due to its ability to interact with certain receptors or ion channels involved in muscle relaxation [1].

description: We consider the scalar sector of a general renormalizable theory and evaluate the effective potential through three loops analytically. We encounter three-loop vacuum bubble diagrams with up to two masses and six lines, which we solve using differential equations transformed into the favorable $ε$ form of dimensional regularization. The master integrals of the canonical basis thus obtained are expressed in terms of cyclotomic polylogarithms up to weight four. We also introduce an algorithm for the numerical evaluation of cyclotomic polylogarithms with multiple-precision arithmetic, which is implemented in the Mathematica package cyclogpl.m supplied here.

A mesoscale study of creep in a microgel using the acoustic radiation force

description: We study the motion of a sphere of diameter 330 $μ$m embedded in a Carbopol microgel under the effect of the acoustic radiation pressure exerted by a focused ultrasonic field. The sphere motion within the microgel is tracked using videomicroscopy and compared to conventional creep and recovery measurements performed with a rheometer. We find that under moderate ultrasonic intensities, the sphere creeps as a power law of time with an exponent $α\simeq 0.2$ that is significantly smaller than the one inferred from global creep measurements below the yield stress of the microgel ($α\simeq 0.4$). Moreover, the sphere relaxation motion after creep and the global recovery are respectively consistent with these two different exponents. By allowing a rheological characterization at the scale of the sphere with forces of the order of micronewtons, the present experiments pave the way for acoustic "mesorheology" which probes volumes and forces intermediate between standard macroscopic rheology and classical microrheology. They also open new questions about the effects of the geometry of the deformation field and of the sphere size and surface properties on the creep behaviour of soft materials.

description: In this paper, a large family of topological black hole solutions of dimensionally continued gravity are derived. The action of Lovelock gravity is coupled to the exponential electrodynamics and the equations of motion are solved in the presence of a pure magnetic source. We work out the metric functions in terms of the parameter $β$ of exponential electrodynamics, and magnetic charge. Further, we couple Lovelock gravity to power-Yang-Mills theory and construct black holes, in diverse dimensions, having Yang-Mills magnetic charge. We also discuss the asymptotic bahaviour of metric functions and curvature invariants at the origin for both the models. The thermodynamics of resulting magnetized black hole solutions in the framework of two different models is also studied. The thermodynamical quantities like Hawking temperature, entropy and specific heat capacity at constant charge are found and we show that the resulting quantities satisfy the first law of black hole thermodynamics. We also study the magnetized hairy black holes of dimensionally continued gravity.
