description: The paper is concerned with the development of efficient and accurate solution procedures for the isogeometric boundary element method (BEM) when applied to problems that contain inclusions that have elastic properties different to the computed domain. This topic has been addressed in previous papers but the approach presented here is a considerable improvement in terms of efficiency and accuracy. One innovation is that initial stresses instead of body forces are used. This then allows a one step solution without iteration. In addition, a novel approach is used for the computation of strains, that avoids the use of highly singular fundamental solutions. Finally, a new type of inclusion is presented that can be used to model reinforcement bars or rock bolts and where analytical integration can be used. Test examples, where results are compared with Finite Element simulations, show that the proposed approach is sound.

description: Acoustic metamaterials constructed from conventional base materials can exhibit exotic phenomena such as negative refractive index, extraordinary transmission-absorption and sub-wavelength imaging. These are typically achieved by combining geometrical and resonance effects. Holey-structured acoustic metamaterials have already shown potential for sub-wavelength acoustic imaging in air, where it is relatively simple to achieve the required difference in acoustic impedance needed to create resonances within the holes. However, the use of polymers for metamaterial operation in water is difficult, due to the much lower difference in acoustic impedance between water and the many polymers used, for example, in additive manufacturing. Hence, metals are commonly used. Here we show that this can be overcome by trapping air layers so that they surround each water-filled channel, making sub-wavelength imaging in water possible. The operation of such a Trapped air design is confirmed at 200-300 kHz ultrasonic frequencies via both finite element modelling and experimental measurements in a water tank. It is also shown quantitatively that the trapped air design outperforms its metal counterpart. The results indicate a way forward for exploiting additive-manufacturing for realising acoustic metamaterials in water at ultrasonic frequencies.

description: In simple models side chains are often represented implicitly (e.g., by spin-states) or simplified as one atom. We study side chain effects using square lattice and tetrahedral lattice models, with explicitly side chains of two atoms. We distinguish effects due to chirality and effects due to side chain flexibilities, since residues in proteins are L-residues, and their side chains adopt different rotameric states. Short chains are enumerated exhaustively. For long chains, we sample effectively rare events (eg, compact conformations) and obtain complete pictures of ensemble properties of these models at all compactness region. We find that both chirality and reduced side chain flexibility lower the folding entropy significantly for globally compact conformations, suggesting that they are important properties of residues to ensure fast folding and stable native structure. This corresponds well with our finding that natural amino acid residues have reduced effective flexibility, as evidenced by analysis of rotamer libraries and side chain rotatable bonds. We further develop a method calculating the exact side-chain entropy for a given back bone structure. We show that simple rotamer counting often underestimates side chain entropy significantly, and side chain entropy does not always correlate well with main chain packing. Among compact backbones with maximum side chain entropy, helical structures emerges as the dominating configurations. Our results suggest that side chain entropy may be an important factor contributing to the formation of alpha helices for compact conformations.

title: Investigation of virulence gene regulation in Streptococcus pneumoniae
Creators: name: Hemsley, Carolyn
Publisher: name: The Open University
Year: 2004

description: Streptococcus pneumoniae is an important human pathogen in all age groups worldwide that causes a variety of diseases, ranging from life threatening septicaemia and meningitis to less severe sinusitis and otitis media. The factors that determine the virulence of S. pneumoniae are very complex but a key aspect of the organism's disease causing potential is the ability of the bacteria to regulate virulence factor expression and activity. In this study two main approaches were taken to investigate virulence gene expression in S. pneumoniae. Firstly, the feasibility of Recombinase based In vivo Expression Technology, RIVET, for use in S. pneumoniae to study gene expression in vitro, and then in vivo was assessed. However, the system was found to be unsuitable for use in this study. Secondly, the requirement for and the role of virulence gene regulators identified by Signature Tagged Mutagenesis were investigated. The requirement for different virulence gene regulators varied according to the murine model of infection used. Two of the regulators, MgrA and RlrA, were essential for nasopharyngeal carriage and production of pneumonia in mice by serotype 4 S. Pneumoniae. Both were shown to control the transcription of genes of a newly described pathogenicity islet, PPI2, encoding RlrA and proteins predicted to act at the bacterial cell surface. The PPI2 genes rlrA and rrgA were shown to be required for adhesion of serotype 4 S. pneumoniae to human epithelial cells and PPI2 gene expression was affected by the gaseous composition of the growth environment in an MgrA dependent manner. The distribution of MgrA, RlrA and PPI2 varied between clinical S. pneumoniae isolates emphasizing the likelihood of a different repertoire of virulence genes and regulators amongst different serotypes and strains of this important human pathogen.

title: The hidden curriculum of the recognition of prior learning: a case study
Creators: name: Harris, Judith Anne
Publisher: name: The Open University
Year: 2004

description: This thesis is a case study of a Recognition of Prior Learning (RPL) practice developed in relation to a university post-graduate level diploma course for educators of adults in a South African university. A review of the literature reveals silences, paradoxes and contradictions around understandings of knowledge, pedagogy, power and identity in RPL. An absence of academic, empirical research at the micro-level of RPL practices is noted. The research foci are concerned with how knowledge(s), pedagogy, power and identity are understood and enacted in and around the case: selected for its intrinsic and atypical qualities and generative interest value. The research draws theoretical resources from the sociology of education (the work of Bernstein) and from continental philosophy (the work of Foucault). It argues for and adopts a hybrid philosophical position, part social constructionist, part structuralist and part poststructuralist, and an interpretive methodology. The RPL case in question had a hidden curriculum which rewarded particular ways of thinking and acting. It confirmed prior experiential knowledge that was similar to that valued in the context and in so doing brought the former under the rule of the latter. The RPL pedagogy was ambiguous, presenting an informal style through which power and control were signalled in a disguised way. 'Success' in RPL in this context was dependent on four prior 'affordances': proximity to vertical discourse, being 'schooled' in reflection, a clear pedagogic identity as an educator and a well-developed learner identity. These affordances were socially distributed but not only along race and class lines. An approach is proposed based on 'knowing the borders and crossing the lines'. This involves theorising relationships between mainstream curricula and pedagogy, RPL curricula and pedagogy, and prior experiential knowledge. It concludes that such approaches might be useful in the broader field of widening participation to higher education.
Quasi-hydrostatic intracluster gas under radiative cooling

description: Quasi-hydrostatic cooling of the intracluster gas is studied. In the quasi-hydrostatic model, work done by gravity on the inflow gas with dP \neq 0, where P is the gas pressure, is taken into account in the thermal balance. The gas flows in from the outer part so as to compensate the pressure loss of the gas undergoing radiative cooling, but the mass flow is so moderate and smooth that the gas is considered to be quasi-hydrostatic. The temperature of the cooling gas decreases toward the cluster center, but, unlike cooling flows with dP = 0, approaches a constant temperature of \sim 1/3 the temperature of the non-cooling ambient gas. This does not mean that gravitational work cancels out radiative cooling, but means that the temperature of the cooling gas appears to approach a constant value toward the cluster center if the gas maintains the quasi-hydrostatic balance. We discuss the mass flow in quasi-hydrostatic cooling, and compare it with the standard isobaric cooling flow model. We also discuss the implication of \dot{M} for the standard cooling flow model.

description: The application of Algorithmic Recourse in decision-making is a promising field that offers practical solutions to reverse unfavorable decisions. However, the inability of these methods to consider potential dependencies among variables poses a significant challenge due to the assumption of feature independence. Recent advancements have incorporated knowledge of causal dependencies, thereby enhancing the quality of the recommended recourse actions. Despite these improvements, the inability to incorporate the temporal dimension remains a significant limitation of these approaches. This is particularly problematic as identifying and addressing the root causes of undesired outcomes requires understanding time-dependent relationships between variables. In this work, we motivate the need to integrate the temporal dimension into causal algorithmic recourse methods to enhance recommendations' plausibility and reliability. The experimental evaluation highlights the significance of the role of time in this field.

description: Exact and approximate procedures for the selection of plant locations are reviewed. An improved version of an approximate procedure developed by Hardy is described that makes use of the SAS computer package. This procedure for site selection introduces a check for dominance among the set of alternative sites. It provides a complete printout of the selection process including optimum sites for systems ranging from one plant to any desired maximum number of plants, product allocation for each system, and the cost of selecting non-optimum combinations. A method of searching for superior site combinations is suggested that is potentially useful for checking systems with small numbers of plants. It is shown that the Hardy algorithm, which relies on a combination improvement check at each step, may fail to find the optimum site set in situations where two sites should be deleted from a previous combination of locations. Instructions for use of the program are included and sample problems provided which illustrate potential applications to pricing and allocation questions.

description: Double ionization (DI) is a fundamental process that despite its apparent simplicity provides rich opportunities for probing and controlling the electronic motion. Even for the simplest multielectron atom, helium, new DI mechanisms are still being found. To first order in the field strength, a strong external field doubly ionizes the electrons in helium such that they are ejected into the same direction (front-to-back motion). The ejection into opposite directions (back-to-back motion) cannot be described to first order, making it a challenging target for control. Here, we address this challenge and optimize the field with the objective of back-to-back double ionization using a (1 + 1)-dimensional model. The optimization is performed using four different control procedures: (1) short-time control, (2) derivative-free optimization of basis expansions of the field, (3) the Krotov method, and (4) control of the classical equations of motion. All four procedures lead to fields with dominant back-to-back motion. All the fields obtained exploit essentially the same two-step mechanism leading to back-to-back motion: first, the electrons are displaced by the field into the same direction. Second, after the field turns off, the nuclear attraction and the electron-electron repulsion combine to generate the final motion into opposite directions for each electron. By performing quasi-classical calculations, we confirm that this mechanism is essentially classical.

title: Identification and characterization of genes preferentially expressed in embryonic telencephalon and CNS stem cells
Creators: name: Faedo, Andrea
Publisher: name: The Open University
Year: 2004

description: One of the major goals in developmental neurobiology is to unravel the molecular programs controlling telencephalic development and neural differentiation. The complexity of brain cell types and circuits is reflected in the complexity of gene expression patterns in the brain. It is believed that perhaps a third to half of all genes are largely or exclusively dedicated to directing development, maintenance and functioning of the brain. In mammals, formation of the complex brain structure occurs over the long period of prenatal development. During this period neural progenitor cells must be instructed to undergo proper proliferation, migration, differentiation and connectivity.

The aim of my study was to identify genes, within a collection of novel genes preferentially expressed in the embryonic telencephalon, controlling such processed in the mammalian forebrain.

To this aim, as a preliminary step, an EST sequencing approach has been undertaken to catalogue and array the repertoire of genes represented in a subtractive library optimized to select rate or unique cDNAs preferentially expressed in the E14.5 mouse telencephalon (named "Telencephalic Embryonic Subtracted Sequences" (Porteus et al., 1992)). The hypothesis driving the production of such a library was that genes preferentially expressed during embryogenesis are likely to be specifically involved in the development of the telencephalon and in the biology of the neural progenitor cells. The selected transcriptome of 1026 unique cDNAs has been used to generate a unique microarray, and to perform gene expression profiling experiments on:
(i) mice mutant for transcription factors involved in forebrain development (D1x1/2, Nkx2.1, Pax6, Ngn1/2),
(ii) in vitro cultured neural stem cells, committed neural progenitor cells (transient amplifying) and terminally differentiated neural cells.

The analysis of the resulting expression profiles has allowed the identification of novel genes that are candidates for playing a major role in neurogenesis and telencephalic development.

The differential expression identified with the Tess has been validated using RNA in situ hybridization on embryonic tissue. Two novel genes (corresponding to Tess 28.8E and Tess 31.5E) have been found to be specifically down regulated in D1x1/2-/- subpallium (-46,51 fold for 28.8E; -6,44 fold for 31.5E), and up regulated in Pax6-/- (4,34 for 28.8E; 3,15 for 31.5E) and Ngn1/2-/- (9,02 for 28.8e; 5,04 for 31.5E) pallium

The microarray experiments on neural stem cells allowed the identification of a selection of genes putatively involved in the process of self-renewal, lineage commitment and differentiation. Some of these genes have been analysed by RNA in situ hybridizations and demonstrated interesting restricted expression patterns in the developing telencephalon.

description: The timing of migration and migratory steps is highly relevant for fitness. Since environmental conditions vary between years, the optimal time for migration varies accordingly. Therefore, migratory animals could clearly benefit from acquiring information as to when it is the best time to migrate in a specific year. Thus, environmental predictability and variability are fundamental characteristics of migration systems but their relation and consequence for migratory progression has remained unexplored. We develop a simple dynamic model to identify the optimal migration behaviour in environments that differ in predictability, variability and the number of intermediate stop-over sites. Our results indicate that higher predictability along migration routes enables organisms to better time migration when phenology deviates from its long-term average and thus, increases fitness. Information is particularly valuable in highly variable environments and in the final migration-step, i.e. before the destination. Furthermore, we show that a general strategy for obtaining information in relatively uninformative but variable environments is using intermediate stop-over sites that enable migrants to better predict conditions ahead. Our study contributes to a better understanding of the relation between animal movement and environmental predictability—an important, yet underappreciated factor that strongly influences migratory progression.

description: The dynamics of a tracer particle in a stationary driven granular gas is investigated. We show how to transform the linear Boltzmann equation describing the dynamics of the tracer into a master equation for a continuous Markov process. The transition rates depend upon the stationary velocity distribution of the gas. When the gas has a Gaussian velocity probability distribution function (pdf), the stationary velocity pdf of the tracer is Gaussian with a lower temperature and satisfies detailed balance for any value of the restitution coefficient $α$. As soon as the velocity pdf of the gas departs from the Gaussian form, detailed balance is violated. This non-equilibrium state can be characterized in terms of a Lebowitz-Spohn action functional $W(τ)$ defined over trajectories of time duration $τ$. We discuss the properties of this functional and of a similar functional $\bar{W}(τ)$ which differs from the first for a term which is non-extensive in time. On the one hand we show that in numerical experiments, i.e. at finite times $τ$, the two functionals have different fluctuations and $\bar{W}$ always satisfies an Evans-Searles-like symmetry. On the other hand we cannot observe the verification of the Lebowitz-Spohn-Gallavotti-Cohen (LS-GC) relation, which is expected for $W(τ)$ at very large times $τ$. We give an argument for the possible failure of the LS-GC relation in this situation. We also suggest practical recipes for measuring $W(τ)$ and $\bar{W}(τ)$ in experiments.

description: Wide-angle cameras are widely used in photogrammetry and autonomous systems which rely on the accurate metric measurements derived from images. To find the geometric relationship between incoming rays and image pixels, geometric camera calibration (GCC) has been actively developed. Aiming to provide practical calibration guidelines, this work surveys the existing GCC tools and evaluates the representative ones for wide-angle cameras. The survey covers camera models, calibration targets, and algorithms used in these tools, highlighting their properties and the trends in GCC development. The evaluation compares six target-based GCC tools, namely, BabelCalib, Basalt, Camodocal, Kalibr, the MATLAB calibrator, and the OpenCV-based ROS calibrator, with simulated and real data for wide-angle cameras described by four parametric projection models. These tests reveal the strengths and weaknesses of these camera models, as well as the repeatability of these GCC tools. In view of the survey and evaluation, future research directions of wide-angle GCC are also discussed.

A Multi-wavelength View of OJ 287 Activity in 2015-2017: Implications of Spectral Changes on Central-engine Models and MeV-GeV Emission Mechanism

description: A diverse range of peculiar properties across the domains of observation have made OJ 287 one of the best-explored BL Lac objects on the issues of relativistic jets and accretion physics as well as the strong theory of gravity. We here present a brief compilation of observational results from the literature and inferences/insights from the extensive studies but focus on the interpretation of its $\sim$ 12-yr QPOOs and high energy emission mechanisms. The QPOOs in one model are attributed to the disk-impact related to dynamics of the binary SMBHs while alternative models attribute it to the geometrical effect related to the precession of a single jet or double jets. We discuss implications of the new spectral features reported during the 2015--2017 multi-wavelength high activity of the source -- a break in the NIR-optical spectrum and hardening of the MeV-GeV emission accompanied by a shift in the location of its peak, in the context of the two. The reported NIR-optical break nicely fits the description of a standard accretion disk emission from an SMBH of mass $\sim~10^{10}~M_\odot$ while the time of its first appearance in end-May 2013 (MJD 56439) is in close coincidence with the time of impact predicted by the disk-impact binary SMBH model. This spectral and temporal coincidence with the model parameters of the disk-impact binary SMBH model provides independent evidence in favor of the model over the geometrical models which argue a total central-engine mass in the range of $\rm 10^{7-9}~M_\odot$. On the other hand, the MeV-GeV spectral change is naturally reproduced by the inverse Compton scattering of photons from the broad-line region and is consistent with the detection of broad emission lines during the previous cycles of quasi-periodic outbursts. Combining this with previous SED studies suggests that in OJ 287, MeV-GeV emission results from external Comptonization.

Abstract

This paper introduces a novel framework linking prime number distributions and phase-locking phenomena to explain the emergence of asymmetry and structured resonance in dynamic systems. We propose that gaps between prime numbers act as natural frequency modulators, driving phase-locking events across multiple scales—cosmic, quantum, biological, and computational. This model provides a new perspective on how chirality, dual-axis condensation (M/E ↔ E/M), and emergent intelligence arise from underlying prime-based resonance patterns.

Abstract

Phase locking, the phenomenon in which oscillatory systems synchronize their frequencies through interaction, is a fundamental organizing principle across multiple domains, including physics, number theory, neuroscience, artificial intelligence, and cosmology. This paper explores how phase locking optimizes coherence in dynamic systems, from prime number distributions to brain activity, AI architectures, and large-scale cosmic structures. By formalizing phase locking within the CODES (Chirality of Dynamic Emergent Systems) framework, we show that intelligence itself emerges as a phase-locked structure in nature, unifying seemingly disparate fields under a single principle of structured resonance.

description: We assume that space-time at the Planck scale is discrete, quantised in Planck units and "qubitsed" (each pixel of Planck area encodes one qubit), that is, quantum space-time can be viewed as a quantum computer. Within this model, one finds that quantum space-time itself is entangled, and can quantum-evaluate Boolean functions which are the laws of Physics in their discrete and fundamental form.

description: This memoir is dedicated to the late Francis Hayin Ree, a formative influence shaping my work in statistical mechanics. Between 1963 and 1968 we collaborated on nine papers published in the Journal of Chemical Physics. Those dealt with the virial series, cell models, and computer simulation. All of them were directed toward understanding the statistical thermodynamics of simple model systems. Our last joint work is also the most cited, with over 1000 citations, "Melting Transition and Communal Entropy for Hard Spheres", submitted 3 May 1968 and published that October. Here I summarize my own most recent work on compressible time-reversible two-dimensional maps. These simplest of model systems are amenable to computer simulation and are providing stimulating and surprising results.

title: A Molecular Epidemiological Investigation of Group B Streptococcus
Creators: name: Jones, Nicola Anne
Publisher: name: The Open University

description: A multilocus sequence typing (MLST) system for group B streptococcus (GBS) has been developed and validated on a global collection of human GBS strains isolated from carriage and invasive disease. A carriage study was performed, over a 3-year period, to establish the rate of carriage of GBS in pregnant women in Oxford, UK. Invasive isolates were collected, prospectively and retrospectively over a similar time period. Twenty-one percent of women studied were asymptomatic carriers of GBS. The incidence of invasive GBS was 0.9/1000 live births in neonates and 6.1/100,000 population >60 years. The population structure of GBS is best depicted. using MLST, as a network of related clusters indicating the presence of recombinational events occurring in the population that interfere with a tree like branching structure of the population. A single hypervirulent clone of GBS (ST-17 complex) is responsible for an excess of neonatal disease in Oxford (odds ratio 3.4). The possibility that a factor other than capsular type III may be responsible for virulence of this clonal complex in neonates is raised. Intriguingly this clonal complex was unique among human lineages in that it has emerged from bovine GBS. It was not however associated with increased invasiveness amongst adult (> 60 years). Further study of this hypervirulent clone of GBS is likely to contribute to the understanding of the pathogenesis of neonatal GBS disease.

description: Continuous-time quantum walks have proven to be an extremely useful framework for the design of several quantum algorithms. Often, the running time of quantum algorithms in this framework is characterized by the quantum hitting time: the time required by the quantum walk to find a vertex of interest with a high probability. In this article, we provide improved upper bounds for the quantum hitting time that can be applied to several CTQW-based quantum algorithms. In particular, we apply our techniques to the glued-trees problem, improving their hitting time upper bound by a polynomial factor: from $O(n^5)$ to $O(n^2\log n)$. Furthermore, our methods also help to exponentially improve the dependence on precision of the continuous-time quantum walk based algorithm to find a marked node on any ergodic, reversible Markov chain by Chakraborty et al. [PRA 102, 022227 (2020)].

description: In a cosmological context dust has been always poorly understood. That is true also for the statistic of GRBs so that we started a program to understand its role both in relation to GRBs and in function of z. This paper presents a composite model in this direction. The model considers a rather generic distribution of dust in a spiral galaxy and considers the effect of changing some of the parameters characterizing the dust grains, size in particular. We first simulated 500 GRBs distributed as the host galaxy mass distribution, using as model the Milky Way. If we consider dust with the same properties as that we observe in the Milky Way, we find that due to absorption we miss about 10% of the afterglows assuming we observe the event within about 1 hour or even within 100s. In our second set of simulations we placed GRBs randomly inside giants molecular clouds, considering different kinds of dust inside and outside the host cloud and the effect of dust sublimation caused by the GRB inside the clouds. In this case absorption is mainly due to the host cloud and the physical properties of dust play a strong role. Computations from this model agree with the hypothesis of host galaxies with extinction curve similar to that of the Small Magellanic Cloud, whereas the host cloud could be also characterized by dust with larger grains. To confirm our findings we need a set of homogeneous infrared observations. The use of coming dedicated infrared telescopes, like REM, will provide a wealth of cases of new afterglow observations.

High-temperature superconductors as ionic metals

description: High-temperature superconductors are reviewed in light of the fact that their binding energy is ionic. The conducting electrons are dominated by the much larger energy scales coming from ligand Coulomb integrals, including the out-of-plane ones, which are responsible for the Fermi arcs. The historic reinterpretation of Hund's rule from an intraelectronic to a central mean-field effect is applied to compare the cuprates to the pnictides. It is argued that the cuprates conform to the now-standard central-field paradigm, while the generally abandoned intraelectronic mechanism is exceptionally applicable to the pnictides. A non-adiabatic Fermi liquid paradigm is inferred from the phenomenological evidence. Glueless superconductivity is interpreted as the limiting case of Cooper-pair scattering in cuprates when the Cu ion is perfectly rigid.

Robustness of prediction for extreme adaptive optics systems under various observing conditions: An analysis using VLT/SPHERE adaptive optics data

description: For high-contrast imaging (HCI) systems, such as VLT/SPHERE, the performance of the system at small angular separations is contaminated by the wind-driven halo in the science image. This halo is a result of the servo-lag error in the adaptive optics (AO) system due to the finite time between measuring the wavefront phase and applying the phase correction. One approach to mitigating the servo-lag error is predictive control. We aim to estimate and understand the potential on-sky performance that linear data-driven prediction would provide for VLT/SPHERE under various turbulence conditions. We used a linear minimum mean square error predictor and applied it to 27 different AO telemetry data sets from VLT/SPHERE taken over many nights under various turbulence conditions. We evaluated the performance of the predictor using residual wavefront phase variance as a performance metric. We show that prediction always results in a reduction in the temporal wavefront phase variance compared to the current VLT/SPHERE AO performance. We find an average improvement factor of 5.1 in phase variance for prediction compared to the VLT/SPHERE residuals. When comparing to an idealised VLT/SPHERE, we find an improvement factor of 2.0. Under our 27 different cases, we find the predictor results in a smaller spread of the residual temporal phase variance. Finally, we show there is no benefit to including spatial information in the predictor in contrast to what might have been expected from the frozen flow hypothesis. A purely temporal predictor is best suited for AO on VLT/SPHERE.
