description: The advent of the Internet and advances in communication have made information ubiquitous. This large availability of information poses risk on its own. Electronic communication is increasingly susceptible to eavesdropping and malicious interventions. Privacy and security are major concerns in this age. In this light, two methods have been brought into existence: Cryptography and Steganography. Cryptography scrambles the message to make it unreadable whereas Steganography masks the existence of the message. Steganographic methods may be spatial-domain (altering the pixel values to hide data) or frequency-domain techniques (altering the frequency coefﬁcients of the image). Spatial domain techniques are more susceptible to steganalysis unlike the frequency-domain techniques. In this paper, I propose a unique pattern based approach for steganography and extended caesar cipher for cryptography. In this approach, the message is ﬁrst encrypted using extended caesar cipher and four patterns are selected to hide the message in the image. The hidden message is secured with an AES-encrypted password, adding an extra layer of security. This method is imperceptible to visible attacks, histogram attacks and statistical attacks since the alterations produced by the method do not bring about a detectable change in the resulting image. Thus, this method provides a new insight into a more secure, efﬁcient and ﬂexible steganographic technique.

description: In this work we have investigated the evolutionary dynamics of a generalist pathogen, e.g. a virus population, that evolves towards specialisation in an environment with multiple host types. We have particularly explored under which conditions generalist viral strains may rise in frequency and coexist with specialist strains or even dominate the population. By means of a nonlinear mathematical model and bifurcation analysis, we have determined the theoretical conditions for stability of nine identified equilibria and provided biological interpretation in terms of the infection rates for the viral specialist and generalist strains. By means of a stability diagram we identified stable fixed points and stable periodic orbits, as well as regions of bistability. For arbitrary biologically feasible initial population sizes, the probability of evolving towards stable solutions is obtained for each point of the analyzed parameter space. This probability map shows combinations of infection rates of the generalist and specialist strains that might lead to equal chances for each type becoming the dominant strategy. Furthermore, we have identified infection rates for which the model predicts the onset of chaotic dynamics. Several degenerate Bogdanov-Takens and zero-Hopf bifurcations are detected along with generalized Hopf and zero-Hopf bifurcations. This manuscript provides additional insights into the dynamical complexity of host-pathogen evolution towards different infection strategies.

description: Charged black holes in a ($2+1$)-dimensional anti-de Sitter space-time suffer from some limitations such as the ambiguity in the definition of the mass and the bad short distance behavior. In this paper we present a way to resolve such issues. By extending the parameter space of the BTZ geometry, we properly identify the integration constants in order to remove the conical singularity sitting at the origin. In such a way we obtain a well defined Minkowski limit and horizons also in the case of de Sitter background space. On the thermodynamic side, we obtain a proper internal energy, by invoking the consistency with the Area Law, even if the mass parameter does not appear in the metric coefficients. As a further improvement, we show that it is sufficient to assume a finite size of the electric charge to obtain a short scale regular geometry. The resulting solution, generalizing the charged BTZ metric, is dual to a van der Waals gas.

A synthetic biology toolbox for electrical control of gene expression
Creators: name: Climent Catala, Alicia
Publisher: name: Imperial College London
Year: 2024

description: There is a growing interest in integrating principles from both biology and electronics to enhance molecular communication within living cells. Synthetic biology and electrogenetics pro- vide a framework for utilising redox mediators and electrochemical signals to modulate gene expression in living cells. A redox-sensitive circuit, based on the bacterial stress response system SoxRS, has been studied and implemented. The SoxRS system comprises a transcription factor that undergoes oxidation in the presence of redox mediators, leading to a conformational change enabling recognition of its promoter, pSoxR, and initiation of the biological response. The activation of SoxR is determined by the oxidation state of redox mediators, controllable through electrochemical signals. However, controlling SoxR activation in the presence of oxygen remains challenging due to respiratory interference, limiting its broad adoption by the metabolic engineering community. This thesis aims to develop and expand a synthetic toolbox based on the electrogenetic SoxR circuit to regulate gene expression using electrochemical signals in aerobic conditions. Firstly, the SoxR redox-sensitive circuit is investigated, assessing its response to various redox cycling molecules, studying its portability to other organisms, and evaluating its impact on cellular metabolism. Secondly, methods for dynamic monitoring of electrogenetic systems are explored, utilising RNA light-up aptamers as transcriptional reporters, unstable fluorescent proteins with high degradation rates, and microfluidic techniques. Thirdly, genetic regulation under aerobic conditions is investigated by implementing a strategy based on the reducing agent TCEP to prevent interference from oxygen in electrochemical regulation. Together, the functionality of the electrogenetic circuit in regulating a metabolic pathway under aerobic conditions is proven, discussing the challenges and showcasing its potential applications in the fields of synthetic biology and metabolic engineering.

description: For a class of frustrated spin lattices including e.g. the 1D sawtooth chain, the 2D kagomé and checkerboard, as well as the 3D pyrochlore lattices we construct exact product eigenstates consisting of several independent, localized one-magnon states in a ferromagnetic background. Important geometrical elements of the relevant lattices are triangles being attached to polygons or lines. Then the magnons can be trapped on these polygons/lines. If the concentration of localized magnons is small they can be distributed randomly over the lattice. Increasing the number of localized magnons their distribution over the lattice becomes more and more regular and finally the magnons condensate in a crystal-like state. The physical relevance of these eigenstates emerges in high magnetic fields where they become groundstates of the system. As a result a macroscopic magnetization jump appears in the zero-temperature magnetization curve just below the saturation field. The height of the jump decreases with increasing spin quantum number and vanishes in the classical limit. Thus it is a true macroscopic quantum effect.

description: The integration of different learning and adaptation techniques to overcome individual limitations and to achieve synergetic effects through the hybridization or fusion of these techniques has, in recent years, contributed to a large number of new intelligent system designs. Computational intelligence is an innovative framework for constructing intelligent hybrid architectures involving Neural Networks (NN), Fuzzy Inference Systems (FIS), Probabilistic Reasoning (PR) and derivative free optimization techniques such as Evolutionary Computation (EC). Most of these hybridization approaches, however, follow an ad hoc design methodology, justified by success in certain application domains. Due to the lack of a common framework it often remains difficult to compare the various hybrid systems conceptually and to evaluate their performance comparatively. This chapter introduces the different generic architectures for integrating intelligent systems. The designing aspects and perspectives of different hybrid archirectures like NN-FIS, EC-FIS, EC-NN, FIS-PR and NN-FIS-EC systems are presented. Some conclusions are also provided towards the end.

description: Evolving graphs in the real world are large-scale and constantly changing, as hundreds of thousands of updates may come every second. Monotonic algorithms such as Reachability and Shortest Path are widely used in real-time analytics to gain both static and temporal insights and can be accelerated by incremental computing. Existing streaming systems adopt the incremental computing model and achieve either low latency or high throughput, but not both. However, both high throughput and low latency are required in real scenarios such as financial fraud detection. This paper presents RisGraph, a real-time streaming system that provides low-latency analysis for each update with high throughput. RisGraph addresses the challenge with localized data access and inter-update parallelism. We propose a data structure named Indexed Adjacency Lists and use sparse arrays and Hybrid Parallel Mode to enable localized data access. To achieve inter-update parallelism, we propose a domain-specific concurrency control mechanism based on the classification of safe and unsafe updates. Experiments show that RisGraph can ingest millions of updates per second for graphs with several hundred million vertices and billions of edges, and the P999 processing time latency is within 20 milliseconds. RisGraph achieves orders-of-magnitude improvement on throughput when analyses are executed for each update without batching and performs better than existing systems with batches of up to 20 million updates.

This was in 1971 when Dual Models were very popular and I had just joined in the efforts. For a number of years I worked on the problem of finding a realistic Dual Model/String Theory for hadrons, and here I will review those efforts as they happened, but also in the light of what we now know about hadrons from QCD. I will argue for when a string picture of hadrons is appropriate and discuss its limitations and the specific results you get from it.

description: We consider a 4+N-dimensional brane world with 2 co-dimension 1 branes in an empty bulk. The two branes have N-1 of their extra dimensions compactified on a sphere S^(N-1), whereas the ordinary 4 spacetime directions are Poincare invariant. An essential input are induced stress-energy tensors on the branes providing different tensions for the spherical and flat part of the branes. The junction conditions - notably through their extra dimensional components - fix both the distance between the branes as well as the size of the sphere. As a result, we demonstrate, that there are no scalar Kaluza-Klein states at all (massless or massive), that would correspond to a radion or a modulus field of S^(N-1). We also discuss the effect of induced Einstein terms on the branes and show that their coefficients are bounded from above, otherwise they lead to a graviton ghost.

description: Ultra-light axions (ULAs) with mass less than 10^-20 eV have interesting behaviors that may contribute to either dark energy or dark matter at different epochs of the Universe. Its properties can be explored by cosmological observations, such as expansion history of the Universe, cosmic large-scale structure, cosmic microwave background, etc. In this work, we study the ULAs with a mass around 10^-33 eV, which means the ULA field still rolls slowly at present with the equation of state w=-1 as dark energy. In order to investigate the mass and other properties of this kind of ULA field, we adopt the measurements of Type Ia supernova (SN Ia), baryon acoustic oscillation (BAO), and Hubble parameter H(z). The Markov Chain Monte Carlo (MCMC) technique is employed to perform the constraints on the parameters. Finally, by exploring four cases of the model, we find that the mass of this ULA field is about 3x10^-33 eV if assuming the initial axion field phi_i=M_pl. We also investigate a general case by assuming phi_i< M_pl and find that the fitting results of phi_i/M_pl are consistent with or close to 1 for the datasets we use.

Hybrid multi-physics and data-driven modelling of bubbly flows in alkaline water electrolysers
Creators: name: Kerhouant, Morgan
Publisher: name: Imperial College London
Year: 2024

description: Alkaline water electrolysers are the primary technology for industrial-scale production of low-carbon hydrogen. Large current densities lead to increased hydrogen production but decreased efficiency due to ohmic, activation, and concentration losses. The two-phase flow plays a significant role, for example, through bubble coverage of the electrode and reduced electrolyte conductivity. At low current densities, product crossover through the diaphragm reduces gas purity, causing production shutdowns to avoid explosive gas mixtures. Understanding the behaviour of the bubbly flow is crucial in improving the design and operation of electrolysers. Direct numerical simulations (DNS) can simulate many fundamental processes in electrolysis, such as bubble growth, detachment, and coalescence. However, their high computational cost prevents the study of larger-scale configurations, leaving gaps in our understanding of industrial electrolysers. Approximations used to simplify the problem introduce significant sources of error and uncertainty, leading existing computational approaches in the literature to employ a range of assumptions of often unknown validity. This thesis introduces a multi-physics model developed with the OpenFOAM libraries, linking multiphase flow, turbulence, population balance modelling, heat transfer and electrochemistry. We validate our computational approach with experimental measurements and examine common assumptions to define a robust numerical configuration. We leverage OpenFOAM's open-source nature to integrate our solver with machine learning and statistical analysis libraries. We first focus on a coarse industrial-scale configuration, conducting a global sensitivity analysis to assess the impact of uncertain parameters, followed by Bayesian optimization to adjust unknown parameters. We then explore physics-informed neural networks to accelerate Poisson equation solvers, applying this to our electrolyser model and the pressure-velocity coupling in incompressible flow solvers. To address uncertainty in two-phase turbulence uncovered in the sensitivity analysis, we perform large-eddy simulations, bridging the gap with the RANS simulations typically used in industry and providing new insights into the flow dynamics within electrolysers.

description: We study a model of a magnetic resonance force microscope (MRFM) based on the cyclic adiabatic inversion technique as a high-resolution tool to detect single electron spins. We investigate the quantum dynamics of spin and cantilever in the presence of coupling to an environment. To obtain the reduced dynamics of the combined system of spin and cantilever, we use the Feynman-Vernon influence functional and get results valid at any temperature as well as at arbitrary system-bath coupling strength. We propose that the MRFM can be used as a quantum measurement device, i.e., not only to detect the modulus of the spin but also its direction.

description: Imaging Atmospheric Cherenkov Telescopes (IACTs) currently in operation feature large mirrors and order of 1 ns time response to signals of a few photo-electrons produced by optical photons. This means that they are ideally suited for optical interferometry observations. Thanks to their sensitivity to visible wavelengths and long baselines optical intensity interferometry with IACTs allows reaching angular resolutions of tens to microarcsec. We have installed a simple optical setup on top of the cameras of the two 17 m diameter MAGIC IACTs and observed coherent fluctuations in the photon intensity measured at the two telescopes for three different stars. The sensitivity is roughly 10 times better than that achieved in the 1970s with the Narrabri interferometer.

description: Quasars accreting matter at very high rates (known as extreme Population A [xA] quasars, possibly associated with super-Eddington accreting massive black holes) may provide a new class of distance indicators covering cosmic epochs from present day up to less than 1 Gyr from the Big Bang. At a more fundamental level, xA quasars are of special interest in studies of the physics of AGNs and host galaxy evolution. However, their observational properties are largely unknown. xA quasars can be identified in relatively large numbers from major optical surveys over a broad range of redshifts, thanks to selection criteria defined from the systematic changes along the quasars main sequence. It has been possible to build a sample of about 250 quasars at low and intermediate redshift, and larger samples can be easily selected from the latest data releases of the Sloan Digital Sky Survey. A large sample can clarify the main properties of xA quasars which are expected - unlike the general population of quasars - to radiate at an extreme, well defined Eddington ratio with small scatter. As a result of the small scatter in Eddington ratio shown by xA quasars, we propose a method to derive the main cosmological parameters based on redshift-independent "virial luminosity" estimates from measurements of emission line widths, roughly equivalent to the luminosity estimates based from line width in early and late type galaxies. A major issue related to the cosmological application of the xA quasar luminosity estimates from line widths is the identification of proper emission lines whose broadening is predominantly virial over a wide range of redshift and luminosity. We report on preliminary developments using the AlIII 1860 intermediate ionization line and the Hydrogen Balmer line H-beta as virial broadening estimators, and we briefly discuss the perspective of the method based on xA quasars.

description: This paper is devoted to constructing some recollements of additive categories associated to concentric twin cotorsion pairs on an extriangulated category. As an application, this result generalizes the work by Chen-Liu-Yang in a triangulated case. Moreover, it highlights new phenomena when it applied to an exact category. Finally, we give some applications to illustrate our main results. In particular, we obtain the Krause's recollement whose the proofs are both elementary and very general.

Nonlocal correlation effects in water and aqueous electrolyte solutions at electrified interfaces
Creators: name: Hedley, Jonathan
Publisher: name: Imperial College London
Year: 2024

description: Of water’s many anomalous properties and characteristics, its ability to influence electrostatic interactions between charged entities is perhaps one of its most profound, with consequences that stretch from the more efficient design of energy storage devices to insights on the origins of life. This ability goes far beyond the primitive solvent model, which considers water as an insulating dielectric, with dielectric constant ε ≈ 80. Being highly polar, and thus strongly correlated in space, water is better described by the language of nonlocal electrostatics. A direct result of its correlated structure, water exhibits strong signatures of overscreening, manifesting in oscillatory patterns in the electric field. This thesis explores these nonlocal correlation effects, and their impact on interactions between charged entities. Employing a field theoretical approach, a bimodal kernel of polarisation correlations was built to mimic the simulated nonlocal dielectric response of water, validated by the faithful reproduction of experimentally measured hydration force profiles. The consequences of this bimodal model are deep, suggesting that oscillations in the electric field are ubiquitous near all electrified interfaces in aqueous solution, and rationalising why these oscillations were sometimes not experimentally observed. Further, water-induced oscillations were found to control the double layer structure at low electrolyte concentrations, leading to ion physisorption in its potential wells. This picture was supported by comparison against atomic force microscopy experiments and capacitance measurements, revealing a marked departure from the classical Gouy-Chapman-Stern model. Applying models of the nonlocal dielectric response of water to DNA, a conceptually similar picture was obtained, supported by atomistic molecular dynamics simulations. Oscillations due to water structure had a strong influence on the surrounding electric field, demonstrating the generality of the results of this thesis. Structured water was also shown to enhance the DNA-DNA pair interaction, substantiating a physical electrostatic mechanism for sequence homology recognition.

description: Recent advances in DNA sequencing open prospects to make whole-genome analysis rapid and reliable, which is promising for various applications including personalized medicine. However, existing techniques for {\it de novo} genome assembly, which is used for the analysis of genomic rearrangements, chromosome phasing, and reconstructing genomes without a reference, require solving tasks of high computational complexity. Here we demonstrate a method for solving genome assembly tasks with the use of quantum and quantum-inspired optimization techniques. Within this method, we present experimental results on genome assembly using quantum annealers both for simulated data and the $ϕ$X 174 bacteriophage. Our results pave a way for an increase in the efficiency of solving bioinformatics problems with the use of quantum computing and, in particular, quantum annealing. We expect that the new generation of quantum annealing devices would outperform existing techniques for {\it de novo} genome assembly. To the best of our knowledge, this is the first experimental study of de novo genome assembly problems both for real and synthetic data on quantum annealing devices and quantum-inspired techniques.

description: We develop a formulation for constructing and examining rapidly rotating Newtonian neutron star models that contain two superfluids, taking account of the effect of the rotation velocity difference between two superfluids. We assume neutron stars to be composed of the superfluid neutrons and the mixture of the superfluid protons and the normal fluid electrons. To describe Newtonian dynamics of the two superfluids, the Newtonian version of the so-called two-fluid formalism is employed. The effect of the rotation velocity difference on the structure of equilibrium state is treated as a small perturbation to rapidly rotating superfluid stars whose angular velocities of two superfluids are assumed to be exactly the same. We derive basic equations for the perturbed structures of rapidly rotating superfluid stars due to the rotation velocity difference between two superfluids. Assuming the superfluids to obey a simple analytical equation of state proposed by Prix, Comer, and Andersson, we obtain numerical solutions for the perturbations and find that the density distributions of the superfluids are strongly dependent on the parameter $σ$ which appears in the analytical equation of state and characterizes the so-called symmetry energy. It is also found that if Prix et al.'s analytical equation of state is assumed, the perturbations can be represented in terms of the universal functions that are independent of the parameters of the equation of state.

title: Taking moral indeterminacy seriously : in defence of compatibility between moral realism and indeterminacy
Creators: name: Kim, Jiwon
Publisher: name: University of St Andrews
Year: 2019

description: Moral indeterminacy appears to be incompatible with moral realism at first glance because moral realists believe that there are objective moral facts in the world, which seem determinate. Given the commitment to objective moral facts, moral realists would want to argue that there can be a considerable amount of convergence on moral matters. However, moral disagreement is too prevalent for realists to be optimistic that there will be convergence sometime in the future. Some moral disagreements seem to remain irresolvable or even faultless. Since it is reasonable to think that moral disagreements arise because there is indeterminacy, moral realists would want to explain indeterminacy without any inconsistency or incompatibility. I argue that moral realism is compatible with every kind of indeterminacy: metaphysical indeterminacy, semantic indeterminacy, and epistemic indeterminacy. What I contribute to indeterminacy and moral realism debate is that, in contrast with how some philosophers argue that all moral indeterminacy can be reduced to metaphysical indeterminacy or epistemicism, I argue that every kind of indeterminacy has its own place. I show that each kind of indeterminacy is helpful for moral realists to explain different types of moral disagreement: faultless moral disagreement can be explained through semantic indeterminacy; irresolvable moral disagreement can be explained through metaphysical indeterminacy; resolvable disagreement can be explained through epistemicism. The upshot of my research is that moral realists can still uphold their tenets on moral objectivity and truth while embracing indeterminacy, the cause of disagreement, at the same time. If the strength of a metaethical theory is measured by how much explanation it can provide, my dissertation shows that moral realism wins over anti-realism in this regard.

description: In recent years, the Internet of Things (IoT) technology has been widely used in the production and sales of tropical fruits, with strong practicability and wide application prospects. The tropical fruit dynamic pricing model based on the IoT technology can promote the healthy development of the tropical fruit industry in Hainan and ensure the income of fruit farmers. Based on IoT technology, the quality grade of tropical fruits in Hainan is obtained. According to the dynamic pricing strategy of revenue management, a dynamic pricing model based on the quality of tropical fruits and a dynamic pricing model based on consumer segmentation are established to study the dynamic pricing problem under the condition of maximum profit for tropical fruit sellers. The research results show that for different fruit quality and consumer groups, different pricing models are required for pricing, in order to get the maximum profit from tropical fruit sales. Sellers must flexibly adopt different dynamic pricing models to price tropical fruits to enhance the competitiveness of the tropical fruit industry.
