description: Within the TMEP, we present a detailed study of the performance of different transport models in Sn+Sn collisions at $270A$ MeV, and put particular emphasis on the production of pions and $Δ$ resonances, which have been used as probes of the nuclear symmetry energy. We prescribe a common and rather simple physics model, and follow in detail the results of 4 BUU models and 6 QMD models. The nucleonic evolution of the collision and the nucleonic observables in these codes do not completely converge, but the differences among the codes can be understood as being due to several reasons: the basic differences between BUU and QMD models in the representation of the phase-space distributions, computational differences in the mean-field evaluation, and differences in the adopted strategies for the Pauli blocking in the collision integrals. For pionic observables, we find that a higher maximum density leads to an enhanced pion yield and a reduced $π^-/π^+$ yield ratio, while a more effective Pauli blocking generally leads to a slightly suppressed pion yield and an enhanced $π^-/π^+$ yield ratio. We specifically investigate the effect of the Coulomb force, and find that it increases the total $π^-/π^+$ yield ratio but reduces the ratio at high pion energies, although differences in its implementations do not have a dominating role in the differences among the codes. Taking into account only the results of codes that strictly follow the homework specifications, we find a convergence of the codes in the final charged pion yield ratio to a $1σ$ deviation of about $5\%$. However, the uncertainty is expected to be reduced to about $1.6\%$ if the same or similar strategies and ingredients, i.e., an improved Pauli blocking and calculation of the non-linear term in the mean-field potential, are similarly used in all codes.

description: We report the direct observation of superconductivity in nitridized-aluminum thin films. The films are produced by sputtering deposition of aluminum in a controlled mixture of nitrogen diluted in argon. The concentration of applied nitrogen directly determines the properties of the superconducting thin films. We observe samples displaying critical temperatures up to 3.38$\pm$0.01K and resilience to in-plane magnetic fields well above 1T, with good reproducibility of the results. This work represents an unambiguous demonstration of tunable superconductivity in aluminum-based nitridized thin films. Our results put forward nitridized aluminum as a promising material to be employed in superconducting quantum circuits for quantum technology applications.

description: We report a robust synthesis of polymeric plasticiser from the post-consumer plastic waste, i.e. poly(ethylene terephthalate) (PET) and its subsequent use as plasticiser for preparation of nitrile rubber (NBR) and nitrile-PVC rubber blends. PET waste was depolymerised by alcoholysis with the help of 1-decanol. The obtained oligomeric plasticiser was characterised for its chemical structure using Fourier Transform Infrared Spectroscopy and Nuclear Magnetic Resonance. The prepared polymeric plasticiser was then used for the preparation of nitrile and nitrile-PVC blend rubber sheets. NBR and nitrile-PVC blend rubber sheets were also prepared by using dioctyl phthalate as plasticiser. The fabricated sheets were compared for their mechanical properties such as tensile strength, elongation at break, hardness. The effect of ageing on mechanical properties was also analysed. It was observed that the use of polymeric plasticiser resulted in significant improvement in tensile properties and ageing resistance. This eco-friendly synthesis of plasticiser offers its use for high-performance applications.

description: We explore the question of whether the interior state of massive red supergiant supernova progenitors can be effectively probed with asteroseismology. We have computed a suite of ten models with ZAMS masses from 15 to 25 m_sun in intervals of 1 m_sun, including the effects of rotation, with the stellar evolutionary code MESA. We estimate characteristic frequencies and convective luminosities of convective zones at two illustrative stages, core helium burning and off-center convective carbon burning. We also estimate the power that might be delivered to the surface to modulate the luminous output considering various efficiencies and dissipation mechanisms. The inner convective regions should generate waves with characteristic periods of ~20 days in core helium burning, ~10 days in helium shell burning, and 0.1 to 1 day in shell carbon burning. Acoustic waves may avoid both shock and diffusive dissipation relatively early in core helium burning throughout most of the structure. In shell carbon burning, years before explosion, the signal generated in the helium shell might in some circumstances be weak enough to avoid shock dissipation, but is subject to strong thermal dissipation in the hydrogen envelope. Signals from a convective carbon-burning shell are very likely to be even more severely damped within the envelope. In the most optimistic case, early in core helium burning, waves arriving close to the surface could represent luminosity fluctuations of a few millimagnitudes, but the conditions in the very outer reaches of the envelope suggest severe thermal damping there.

description: Quantum mechanical concept such as the Casimir effect is explored to model traversable wormholes in an extended teleparallel gravity theory. The minimal length concept leading to the generalized uncertainty principle (GUP) is used to obtain the Casimir energy density. The effect of the GUP correction in the geometrical and physical properties of traversable Casimir wormholes are investigated. It is noted that the GUP correction has a substantial effect on the wormhole geometry and it modifies the energy condition. From a detailed calculation of the exotic matter content of the GUP corrected Casimir wormhole, it is shown that, a minimal amount of exotic matter is sufficient to support the stability of the wormhole.

description: Adapters and Low-Rank Adaptation (LoRA) are parameter-efficient fine-tuning techniques designed to make the training of language models more efficient. Previous results demonstrated that these methods can even improve performance on some classification tasks. This paper complements the existing research by investigating how these techniques influence the classification performance and computation costs compared to full fine-tuning when applied to multilingual text classification tasks (genre, framing, and persuasion techniques detection; with different input lengths, number of predicted classes and classification difficulty), some of which have limited training data. In addition, we conduct in-depth analyses of their efficacy across different training scenarios (training on the original multilingual data; on the translations into English; and on a subset of English-only data) and different languages. Our findings provide valuable insights into the applicability of the parameter-efficient fine-tuning techniques, particularly to complex multilingual and multilabel classification tasks.
Development of novel 3D porous melt-derived bioactive glass scaffolds
Creators: name: Wu, Zoe Yunxie
Publisher: name: Imperial College London
Year: 2010

description: The aim of this thesis is to develop a method to produce melt-derived bioactive glass scaffolds, without the glass crystallizing into a glass-ceramic, while establishing an interconnected pore network suitable for bone tissue regeneration. In order to achieve this, the scaffold must have the ability to closely mimic the porous structure of cancellous bone and its mechanical properties. Two bioactive glasses were used in this project, both are modified from the Bioglass® composition: ICIE 16 (49.46% SiO2, 36.27% CaO, 6.6% Na2O, 6.6% K2O and 1.07% P2O5, all in mol%) and ICIE 16M (49.46% SiO2, 27.27% CaO, 6.6% Na2O, 6.6% K2O, 3% ZnO, 3% MgO, 3% SrO and 1.07% P2O5, all in mol%). Gel-cast foaming produced improved pore networks over alternative methods for producing porous scaffolds. There are many variables in the process. An initial protocol was established and each of the variables assessed systematically. The relationships between each component, the gelling time and the foam body volume were evaluated to develop an optimized protocol for the process. The size of the glass powder was critical in determining the sintering efficiency. A suitable drying and sintering program was also determined to prevent crystallization of the glass and formation of crystal species from by-products of the process. The scaffolds were characterized in terms of the interconnect size, the rate of hydroxycarbonate apatite (HCA) formation in simulated body fluid (SBF) solutions, the ion release rate and the compressive strength. The results showed that ICIE 16M sintered better and was stronger than ICIE 16, however in the bioactivity aspect of view, the rate of HCA formation in SBF was faster for ICIE 16 than ICIE 16M.
Molecular theories and simulation of ions and polar molecules in water

description: Recent developments in molecular theories and simulation of ions and polar molecules in water are reviewed. The hydration of imidazole and imidazolium solutes is used to exemplify the theoretical issues. The treatment of long-ranged electrostatic interactions in simulations is discussed extensively. It is argued that the Ewald approach is an easy way to get correct hydration free energies in the thermodynamic limit from molecular calculations; and that molecular simulations with Ewald interactions and periodic boundary conditions can also be more efficient than many common alternatives. The Ewald treatment permits a conclusive extrapolation to infinite system size. The picture that emerges from testing of simple models is that the most prominent failings of the simplest theories are associated with solvent proton conformations that lead to non-gaussian fluctuations of electrostatic potentials. Thus, the most favorable cases for the second-order perturbation theories are monoatomic positive ions. For polar and anionic solutes, continuum or gaussian theories are less accurate. The appreciation of the specific deficiencies of those simple models have led to new concepts, multistate gaussian and quasi-chemical theories, that address the cases for which the simpler theories fail. It is argued that, relative to direct dielectric continuum treatments, the quasi-chemical theories provide a better theoretical organization for the computational study of the electronic structure of solution species.

description: In this paper, we present algorithms for reconstructing an unknown compact scatterer embedded in a random noisy background medium, given measurements of the scattered field and information about the background medium and the sound profile. We present six different methods for the solution of this inverse problem using different amounts of scattered data and prior information about the random background medium and the scatterer. The different inversion algorithms are defined by a combination of stochastic programming methods and Bayesian formulation. Our basic results show that if we have data for just one instance of the random background medium the best strategy is to invert for both random medium and unknown scatterer with appropriate regularization. However, if we have data for multiple instances of the medium it may be worth solving a coupled set of multiple inverse problems. We present several numerical results for inverting for various scatterer geometries under different inversion scenarios. The main take-away of our study is that one should invert for both unknown scatterer and random medium, with appropriate, prior-information based regularization. Furthermore, if data from multiple realizations of the background medium is available, then it may be beneficial to combine results from multiple inversions.

description: The Agriculture of the Iron Age Experimental archaeology endeavors to improve the techniques of excavation and analysis by trying to find the conditions in which archaeological structures have been formed. Rather than simulating the lives of men at the Iron Age, Peter Reynolds' team preferred to develop an experimental farm to take into account and study all the farm activities of that period. The temporal dimension of this project makes it possible to study the evolution of a plant or animal production, the aging process of a dwelling or the way in which a ditch is filled. These results provide lessons that are easily applicable in the field and can thus solve some of the difficulties experienced by all excavators.

Inhibiting influenza virus replication using novel and established antiviral compounds
Creators: name: Brookes, Daniel William
Publisher: name: Imperial College London
Year: 2010

description: Circulating influenza viruses have the potential to cause pandemics, as seen in 2009 with the emergence of a novel H1N1 virus that rapidly disseminated worldwide. In such an event, huge reliance is placed upon antiviral drugs for the prophylaxis and treatment of influenza infections. To date, only two different classes of antiviral drug are licensed for the treatment of influenza and only one of these, oseltamivir, has been stockpiled by major world governments in preparation for an influenza pandemic. However, widespread resistance to this drug has been documented in seasonal circulating strains, which emerged in the absence of intense drug use and predominated over drug-sensitive phenotypes. Furthermore, examples of oseltamivir resistant viruses have been found sporadically in pandemic A/H1N1 2009 influenza strains. The need for novel antivirals is therefore essential for effective infection control of influenza viruses in future years. A potential source of novel therapies are licensed compound libraries. We begin with the screening of two compound libraries, resulting in the identification of several compounds which inhibited influenza virus replication in vitro. After completing a traditional library screen, a novel approach to high-throughput compound screening using reporter plasmids expressed in a stable cell line was attempted. Although these cell-lines did not prove maintainable in the long-term, this work resulted in the generation of a reporter plasmid that is directly initiated by influenza infection in vitro and is thus a useful tool for assaying polymerase fitness of different influenza strains. The investigation then focused on one of the newly discovered hits and attempted to identify the spectrum of activity of this compound, a glycosylation inhibiting molecule, which was shown to be efficacious against influenza A strains only. The drug was shown to have low toxicity and proved active against the recently emerged pandemic influenza virus. The thesis then documents the effects of a common oseltamivir-resistant mutation, H275Y, on the neuraminidase protein of a representative 2009 pandemic influenza virus. This mutation was well tolerated in vitro by the virus and did not handicap replication in a human airway epithelial model. However, subtle impediments to the neuraminidase activity of the mutant were observed biochemically which may suggest why this mutation has not emerged more readily in the field.
MEMS micro-contact printing engines
Creators: name: Choonee, Kaushal R V
Publisher: name: Imperial College London
Year: 2010

description: This thesis investigates micro-contact printing (µCP) engines using micro-electro-mechanical systems (MEMS). Such engines are self-contained and do not require further optical alignment and precision manipulation equipment. Hence they provide a low-cost and accessible method of multilevel surface patterning with sub-micron resolution. Applications include the field of biotechnology where the placement of biological ligands at well controlled locations on substrates is often required for biological assays, cell studies and manipulation, or for the fabrication of biosensors. A miniaturised silicon µCP engine is designed and fabricated using a wafer-scale MEMS fabrication process and single level and bi-level µCP are successfully demonstrated. The performance of the engine is fully characterised and two actuation modes, mechanical and electrostatic, are investigated. In addition, a novel method of integrating the stamp material into the MEMS process flow by spray coating is reported. A second µCP engine formed by wafer-scale replica moulding of a polymer is developed to further drive down cost and complexity. This system carries six complementary patterns and allows six-level µCP with a layer-to-layer accuracy of 10 µm over a 5 mm x 5 mm area without the use of external aligning equipment. This is the first such report of aligned multilevel µCP. Lastly, the integration of the replica moulded engine with a hydraulic drive for controlled actuation is investigated. This approach is promising and proof of concept has been provided for single-level patterning.

description: In the field of ergodicity-breaking phases, it has been recognized that quantum avalanches can destabilize many-body localization at a wide range of disorder strengths. This has in particular been demonstrated by the numerical study of a toy model, sometimes simply called the "avalanche model" or the "quantum sun model" [Phys. Rev. Lett. 129, 060602 (2022)], which consists of an ergodic seed coupled to a perfectly localized material. In this paper, we connect this toy model to a well-studied model in random matrix theory, the ultrametric ensemble. We conjecture that the models share the following features. 1) The location of the critical point may be predicted sharply by analytics. 2) On the localized site, both models exhibit Fock space localization. 3) There is a manifold of critical points. On the critical manifold, the eigenvectors exhibit nontrivial multifractal behaviour that can be tuned by moving on the manifold. 4) The spectral statistics at criticality is intermediate between Poisson statistics and random matrix statistics, also tunable on the critical manifold. We confirm numerically these properties.

description: Malaria remains one of the world’s most devastating vector-borne parasitic diseases and existing control tools may not be enough to meet the challenge of eliminating malaria in areas of high transmission. Understanding the population dynamics of Plasmodium within the mosquito vector is essential for developing, optimising, and evaluating novel control measures aimed at reducing transmission by targeting this important interface. Malaria research and mathematical models of transmission classically assume that the processes involved in the progression and development of the Plasmodium parasite within Anopheles mosquitoes are independent of parasite density. The research presented in this thesis challenges this assumption, investigating the impact of parasite density on population processes and regulation. A multidisciplinary approach has been taken, including statistical analyses, practical experimentation, and mathematical modelling. The results show that the progression of the rodent malaria Plasmodium berghei through Anopheles stephensi mosquitoes depends nonlinearly on parasite density, with the presence of both negative and positive density-dependent processes in operation. Analyses of other Plasmodium– Anopheles species combinations also indicate that the traditional assumption of density independence may be an oversimplification. Experimental investigation of mosquito mortality illustrates that the survival of a mosquito depends both on mosquito age and parasite density, again in contrast to the assumptions of malaria transmission modelling. A framework for a mathematical model tracking Plasmodium density within the mosquito has been developed as part of this thesis. Further investigation of sporogonic processes will allow this model to be further refined and extended for use in the future design and evaluation of interventions which target the mosquito or the parasite whilst within the vector.

description: We develop the concept of trajectories in anyon spectra, i.e., the continuous dependence of energy levels on the kinetic angular momentum. It provides a more economical and unified description, since each trajectory contains an infinite number of points corresponding to the same statistics. For a system of non-interacting anyons in a harmonic potential, each trajectory consists of two infinite straight line segments, in general connected by a nonlinear piece. We give the systematics of the three-anyon trajectories. The trajectories in general cross each other at the bosonic/fermionic points. We use the (semi-empirical) rule that all such crossings are true crossings, i.e.\ the order of the trajectories with respect to energy is opposite to the left and to the right of a crossing.

description: We show that a reddening sequence exists for any quiver which is Banff. Our proof is combinatorial and relies on the triangular extension construction for quivers. The other facts needed are that the existence of a reddening sequence is mutation invariant and passes to induced subquivers. Banff quivers define locally acyclic cluster algebras which are known to coincide with their upper cluster algebras.The existence of reddening sequences for these quivers is consistent with a conjectural relationship between the existence of a reddening sequence and a cluster algebra's equality with its upper cluster algebra.Our result completes a verification of the conjecture for Banff quivers. We also prove that a certain subclass of quivers within the class $\mathcal{P}$ define locally acyclic cluster algebras.

description: Logs are an essential source of information for people to understand the running status of a software system. Due to the evolving modern software architecture and maintenance methods, more research efforts have been devoted to automated log analysis. In particular, machine learning (ML) has been widely used in log analysis tasks. In ML-based log analysis tasks, converting textual log data into numerical feature vectors is a critical and indispensable step. However, the impact of using different log representation techniques on the performance of the downstream models is not clear, which limits researchers and practitioners' opportunities of choosing the optimal log representation techniques in their automated log analysis workflows. Therefore, this work investigates and compares the commonly adopted log representation techniques from previous log analysis research. Particularly, we select six log representation techniques and evaluate them with seven ML models and four public log datasets (i.e., HDFS, BGL, Spirit and Thunderbird) in the context of log-based anomaly detection. We also examine the impacts of the log parsing process and the different feature aggregation approaches when they are employed with log representation techniques. From the experiments, we provide some heuristic guidelines for future researchers and developers to follow when designing an automated log analysis workflow. We believe our comprehensive comparison of log representation techniques can help researchers and practitioners better understand the characteristics of different log representation techniques and provide them with guidance for selecting the most suitable ones for their ML-based log analysis workflow.

description: The construction of the Pimperne Round House and its subsequent dismantlement have already been reported (Harding, Blake & Reynolds 1993). This paper seeks to focus upon one specific aspect/discovery made during the dismantlement process which has considerable significance for future analysis of prehistoric round houses on two specific events: first, the projected longevity of such a structure, and second, the nature of materials finds from principal post-holes. For these latter, the probability that their deposition of co-evel with the early phases of the occupation of the structure is far greater than their representing a post-depositional phase of the site.
Chemical probes of surface layer biogenesis in Clostridium difficile

description: The bacterium Clostridium difficile is responsible for recent epidemics of gastroenteritis and currently causes over twice as many deaths per year as the other major hospital ‘superbug’, MRSA. Since the bacterium is resistant to conventional antibiotics there is an urgent need to develop novel therapies. C. difficile secretes a family of proteins that are held in place on the cell wall by non-covalent forces, producing a proteinaceous coat (the surface layer or S-layer) that surrounds the entire cell. These S-layer proteins (SLPs) are immunogenic in humans and play a role in binding to host cells. Synthesis of the C. difficile S-layer involves site-specific proteolytic cleavage of the SlpA precursor by an as yet unidentified C. difficile protease. Identification of the protease that processes SlpA has proven challenging, due in part to a lack of established genetic tools in C. difficle. Here the development of novel chemical probes that can disrupt S-layer formation by inhibiting the protease are described, and found to be powerful chemical proteomic tools for both protease identification and exploring the process of S-layer formation. Screening and inhibition experiments were first performed to identify novel synthetic irreversible protease inhibitors combining an electrophilic warhead with a specific sequence element matching the SlpA cleavage. These compound series were shown to possess structure-dependent activity, and inhibited cultures were also more sensitive to lysozyme-induced cell lysis, suggesting that correct processing and assembly of the S-layer is important for cell envelope integrity. Optimised inhibitors were further developed into ‘activity-based probes’ (ABPs) carrying an affinity tag, and were successfully used to isolate and identify de novo the key protease involved in cleavage of SlpA, Cwp84, using a combination of different labelling and proteomics approaches. These probes also permitted identification of Cwp84 activity across a wide range of clinical strains. In later work, the scope of the warhead element was explored in more detail, and the potential antibacterial effects of the inhibitors were investigated in both wild type and genetically engineered strains. Finally, the contributions of this work in terms of both chemical technology and C. difficile biology are critically assessed.
The Design and Development of a Wearable Prototype Device to Monitor Movement of the Lumbar Spine and Pelvis

description: Chronic Low Back Pain (CLBP) is a leading cause of disability with high economic costs and severe psychological and social consequences. Difficulties in the management of Low Back Pain (LBP) include: credibility of self-reported health and function surveys, accurate patient evaluation and identifying reassessment time. The most critical issue is the assessment of LBP severity at a single point of time during clinic visits, rather than through continuous monitoring at home or in the workplace. This thesis describes the selection of parameters indicative of LBP impact on daily function followed by the design, development, testing, validation, and evaluation of a wearable prototype device that monitors the movement of the lumbar spine and pelvis simultaneously, and quantifies the motion characteristics. I identified three areas of disability and measurable parameters, proposed suitable sensing technologies and a placement map. Focussing on monitoring movement of the lumbar spine and pelvis, I investigated the use of inertial sensor technology and a miniaturised, cost effective, wireless sensor platform. On confirming reliability and reproducibility of the sensor signals for different movements, customised sensor boards, Graphical User Interface (GUI), application software and analytical procedures were developed to enable data acquisition from two networked sensor nodes. After investigating possible wearable strategies, I designed a unique sensor case and fixation method. Ethics approval was available only for healthy participants and I conducted a Pilot Study with the developed prototypes on 16 volunteers performing movements affected in LBP patients. The intra and inter-subject analyses of 11 participants demonstrated that the developed sensor prototypes correctly monitor the movements, measure consistent angular velocities and range of motion within a participant, detect similarities and differences between participants, and reveal the lumbar and pelvic contribution during movements. The two wireless sensors measure lumbo-pelvic motion simultaneously. The results are very promising and the sensor prototype can be tested with CLBP patients.

description: We present an explicit study of the holographic renormalization group (RG) in six dimensions using minimal gauged supergravity. By perturbing the theory with the addition of a relevant operator of dimension four one flows to a non-supersymmetric conformal fixed point. There are also solutions describing non-conformal vacua of the same theory obtained by giving an expectation value to the operator. One such vacuum is supersymmetric and is obtained by using the true superpotential of the theory. We discuss the physical acceptability of these vacua by applying the criteria recently given by Gubser for the four dimensional case and find that those criteria give a clear physical picture in the six dimensional case as well. We use this example to comment on the role of the Hamilton-Jacobi equations in implementing the RG. We conclude with some remarks on AdS_4 and the status of three dimensional superconformal theories from squashed solutions of M-theory.

description: This paper examines the intergenerational transmission of gender attitudes in India, a setting with severe discrimination against women and girls. We use survey data on gender attitudes (specifically, about the appropriate roles and rights of women and girls) collected from nearly 5500 adolescents attending 314 schools in the state of Haryana, and their parents. We find that when a parent holds a more discriminatory attitude, his or her child is about 11 percentage points more likely to hold the view. We find that parents hold greater sway over students’ gender attitudes than their peers do, and that mothers influence children’s gender attitudes more than fathers. Parental attitudes influence child attitudes more in Scheduled Caste communities and student gender attitudes are positively correlated with behaviours such as interacting with children of the opposite gender.
