description: A closed equilateral random walk in 3-space is a selection of unit length vectors giving the steps of the walk conditioned on the assumption that the sum of the vectors is zero. The sample space of such walks with $n$ edges is the $(2n-3)$-dimensional Riemannian manifold of equilateral closed polygons in $\mathbb{R}^3$. We study closed random walks using the symplectic geometry of the $(2n-6)$-dimensional quotient of the manifold of polygons by the action of the rotation group $\operatorname {SO}(3)$. The basic objects of study are the moment maps on equilateral random polygon space given by the lengths of any $(n-3)$-tuple of nonintersecting diagonals. The Atiyah-Guillemin-Sternberg theorem shows that the image of such a moment map is a convex polytope in $(n-3)$-dimensional space, while the Duistermaat-Heckman theorem shows that the pushforward measure on this polytope is Lebesgue measure on $\mathbb{R}^{n-3}$. Together, these theorems allow us to define a measure-preserving set of "action-angle" coordinates on the space of closed equilateral polygons. The new coordinate system allows us to make explicit computations of exact expectations for total curvature and for some chord lengths of closed (and confined) equilateral random walks, to give statistical criteria for sampling algorithms on the space of polygons and to prove that the probability that a randomly chosen equilateral hexagon is unknotted is at least $\frac{1}{2}$. We then use our methods to construct a new Markov chain sampling algorithm for equilateral closed polygons, with a simple modification to sample (rooted) confined equilateral closed polygons. We prove rigorously that our algorithm converges geometrically to the standard measure on the space of closed random walks, give a theory of error estimators for Markov chain Monte Carlo integration using our method and analyze the performance of our method. Our methods also apply to open random walks in certain types of confinement, and in general to walks with arbitrary (fixed) edgelengths as well as equilateral walks.

description: Systemic social inequities can be formed and maintained through explicitly degrading language such as hate speech and slurs but how might humans accomplish this implicitly? Previous research has pointed to language as a potential vehicle for implicit bias, but it is not yet known what specific set of linguistic markers might underlie devaluing language regardless of context. In two studies using large, real-world data, the current project explored the ways that grammatical, structural and contextual features of language communicate the relative worth of social groups. Using varied methods in natural language processing including dictionary-based approaches, topic modeling, named entity recognition, and parts of speech tagger, the current work gives promising candidates for devaluing language. In Study 1, text analyses were conducted on 18,264 missing persons reports from a large national database. Results indicated that non-White missing persons reports contained fewer words, less detail, less affect and were more likely to feature active (i.e., implying personal fault) rather than passive language. Similarly, non-White missing persons reports were more likely to feature words like “runaway” rather than “disappeared” or “missing,” again implying that the victim played an active role in their disappearance. Black missing persons reports in particular also feature less personal pronoun use. In Study 2, 199,941 tweets discussing 30 mass shootings in the US were analyzed to investigate if the language candidates found in Study 1 could be replicated in a different context. Specifically, the study examined the ways that language may be differentially impacted depending on the race of the victims under discussion. Effects for word count, detail and passivity were replicated while contrary findings in affect and personal pronoun use point to the potential impact of context and individual differences (e.g., political affiliation) in buffering or augmenting devaluing language. The implications for systemic disparities in multiple domains are discussed using language as a lens.

description: There are several issues to do with dwarf galaxy predictions in the standard $Λ$CDM cosmology that have suscitated much recent debate about the possible modification of the nature of dark matter as providing a solution. We explore a novel solution involving ultra-light axions that can potentially resolve the missing satellites problem, the cusp-core problem, and the `too big to fail' problem. We discuss approximations to non-linear structure formation in dark matter models containing a component of ultra-light axions across four orders of magnitude in mass, $10^{-24}\text{ eV}\lesssim m_a \lesssim 10^{-20}\text{ eV}$, a range too heavy to be well constrained by linear cosmological probes such as the CMB and matter power spectrum, and too light/non-interacting for other astrophysical or terrestrial axion searches. We find that an axion of mass $m_a\approx 10^{-21}\text{ eV}$ contributing approximately $85\%$ of the total dark matter can introduce a significant kpc scale core in a typical Milky Way satellite galaxy in sharp contrast to a thermal relic with a transfer function cut off at the same scale, while still allowing such galaxies to form in significant number. Therefore ultra-light axions do not suffer from the \emph{Catch 22} that applies to using a warm dark matter as a solution to the small scale problems of cold dark matter. Our model simultaneously allows formation of enough high redshift galaxies to allow reconciliation with observational constraints, and also reduces the maximum circular velocities of massive dwarfs so that baryonic feedback may more plausibly resolve the predicted overproduction of massive MWG dwarf satellites.

title: Characterising the structure and activity of the Ebola virus Delta Peptide
Creators: name: Towler, Eleanor
Publisher: name: University of Kent
Year: 2022

description: The Ebola virus is a highly pathogenic virus that emerged in 1976 and remains a pressing research target due to its rapid transmission and potential to cause widespread, fatal pandemics. The Ebola virus encodes seven proteins produced following infection that aid with its replication and infection of further cells. One of these proteins is a small peptide called Delta Peptide (DP) which is produced as a result of the cleavage of a glycoprotein following RNA editing. DP is one of the few Ebola proteins whose structure remains unsolved and its function is widely unknown. It is predicted that DP behaves as a Viroporin. The aim of this project was to investigate the activity of DP and how this may relate to or be dependent on its structure. DP activity was investigated through the use of dye leakage assays and a UV microscopy membrane insertion assay. These confirm predictions that DP inserts into asolectin lipid membranes and forms pores to permeabilize the membrane. DP has also been predicted to have a mainly α-helical structure using circular dichroism (CD) and nuclear magnetic resonance (NMR). The NMR experiments also demonstrate protein-lipid interactions occurring when DP was added to asolectin vesicles and suggest a structural change occurred. This project concluded that DP is likely an α-helical peptide able to inserts into asolectin membranes causing Viroporin like permeabilization. It also indicates that this membrane permeabilization is possible when DP is in its oxidised or reduced state and in the absence of its C-terminal portion and Trp25.

description: In the classification of real singularities by Arnold et al. (1985), normal forms, as representatives of equivalence classes under right equivalence, are not always uniquely determined. We describe the complete structure of the equivalence classes of the unimodal real singularities of corank 2. In other words, we explicitly answer the question which normal forms of different type are equivalent, and how a normal form can be transformed within the same equivalence class by changing the value of the parameter. This provides new theoretical insights into these singularities and has important consequences for their algorithmic classification.

description: Detecting regional spatial structures based on spatial interactions is crucial in applications ranging from urban planning to traffic control. In the big data era, various movement trajectories are available for studying spatial structures. This research uses large scale Shanghai taxi trip data extracted from GPS-enabled taxi trajectories to reveal traffic flow patterns and urban structure of the city. Using the network science methods, 15 temporally stable regions reflecting the scope of people's daily travels are found using community detection method on the network built from short trips, which represent residents' daily intra-urban travels and exhibit a clear pattern. In each region, taxi traffic flows are dominated by a few 'hubs' and 'hubs' in suburbs impact more trips than 'hubs' in urban areas. Land use conditions in urban regions are different from those in suburban areas. Additionally, 'hubs' in urban area associate with office buildings and commercial areas more, whereas residential land use is more common in suburban hubs. The taxi flow structures and land uses reveal the polycentric and layered concentric structure of Shanghai. Finally, according to the temporal variations of taxi flows and the diversity levels of taxi trip lengths, we explore the total taxi traffic properties of each region and proved the city structure we find. External trips across regions also take large proportion of the total traffic in each region, especially in suburbs. The results could help transportation policy making and shed light on the way to reveal urban structures with big data.

"Their ethos is all about building trust": An Exploration of Staff-Prisoner Relationships at a Women's Open Prison
Creators: name: Waite, Sarah
Publisher: name: Leeds Beckett University
Year: 2023
Subjects: Uncategorized

description: There is a body of work that acknowledges the importance of staff-prisoner relationships and describes their complex nature in various carceral contexts. Penological themes of power and authority dominate these discussions, and it is only recently that analyses of trust have begun to emerge. Although it has been acknowledged that trust is of central importance to the lives of women in prison, there is a dearth of literature exploring trust in staff-prisoner relationships. Moreover, explorations of staff-prisoner relationships within the women’s open estate have not featured as a central focus within the penological literature. The open prison is presented as an institution of progression for incarcerated women and, despite accounting for a small proportion of the prison population, offers an important site of analyses for carceral relationships and experiences of trust. Using grounded theory and appreciative inquiry, this thesis presents the findings of semi-structured interviews with incarcerated women and staff at an open prison, exploring the ways in which regime and practice create and foster trust in carceral relationships. Key findings from this empirical research study indicate that staff-prisoner relationships at the women’s open prison are complex and experienced as distinct. The open regime plays an integral role in shaping these relationships, alongside the attitudes and practice of the staff and women within them. Significantly, these findings demonstrate that trust is shaped by the prison itself and therefore operates in a carceral manner. Trust was found to be pervasive, and this filtered through to the operation of relational dynamics. Notably, although trust was limited and constrained, there was evidence of thicker interpersonal trust when relationships overcame explicit carceral symbols and both women and staff were humanised. The thesis concludes that attention should be paid to uncritical notions of trust in carceral settings and the ways in which institutions can shape complex operational and penological themes.

Proteins and peptides

description: Protein kinases are essential in cell signaling pathways and are well-validated targets for cancer therapeutics and detection of activity levels. Yet, there remains a critical need for kinase inhibitors with high specificity and potency. The development of DNA-encoded library (DEL) technology dramatically facilitates the discovery of ligands to therapeutically relevant proteins. The preparation of combinatorial libraries followed by stringent selections can be exploited to rapidly generate hit molecules that bind to a large variety of targets. A combinatorial library of peptidomimetics is prepared and subjected to a selection for enriching molecules that can serve as substrates for tyrosine kinase Src. Non-natural substrate molecules are recognized by the anti-phosphotyrosine antibody during the selection. Using biophysical characterization assays including ADP-Glo and NMR, the resulting hits are investigated as novel peptide-substrate competitive inhibitors, as well as specific chemical probes that would benefit kinase activity detection. An ester derivative of the lead compound SrcDEL10 demonstrates cellular activity with inhibition of Src-dependent signaling in cell culture. Subsequently, our effort extends to parallel selections with a highly diverse-scaffold DEL on three cancer-related tyrosine kinases. Several hit molecules are validated with differential phosphotransfer activities among Src, Lyn, and Syk. Studies on the structure activity relationship of hit molecules produce selective kinase substrates with the lowest molecular weights reported to date. Potential bisubstrate inhibitors, showing above 8-fold Src selectivity over Lyn, are designed based on structures of selective substrates. Meanwhile, high sensitivity of DNA sequence analysis enables the development of specific and multiplexed activity assays. Using the substrate selection strategy, we develop a DNA-based kinome activity profiling assay using DNA conjugates of tyrosine kinase peptide substrates. Selective enrichment of phosphorylated probes enables activity detection by either quantitative PCR (qPCR) or parallel DNA sequencing. Results with detecting recombinant kinases demonstrated a low (~50 pM kinase) limit of detection. A library of 96 DNA-substrate conjugates enabled multiplexed tyrosine kinase assays in cell lysates in a manner analogous to peptide microarrays. This DNA-based assay potentially empowers the detection of tumor biomarkers with high specificity, lower detection limit, multiplexing capability, and high cost-effectiveness. Together, this research uses DNA-based technologies to assist developing new therapeutics and diagnostics, drug target validation, unveiling drug mechanisms of action, and understanding the role of protein phosphorylation in disease progression.

description: We add a minimal correction term to the local Gross-Pitaevskii equation to represent non-locality in the interactions. We show that the effective minimal non-locality can make the healing length decrease more rapidly with the increase of $s$-wave scattering length leaving the expression of the velocity of sound unaltered. We discuss the implication of this result for a Bose-Einstein Condensate (BEC) being used as an analogue gravity system. The presented result is important in the context of condensed matter physics as well because one can considerably change the size of a quantized vortex at finite $s$-wave scattering length by tuning the healing length.

Both linear confinement and chiral symmetry breaking of low energy QCD are well characterized in such an infrared-improved soft-wall AdS/QCD model. The model enables us to obtain a more consistent numerical prediction for the mass spectra of resonance scalar, pseudoscalar, vector and axial-vector mesons. In particular, the predicted mass for the lightest ground state scalar meson shows a good agreement with the experimental data. The model also provides a remarkable check for the Gell-Mann-Oakes-Renner relation and a sensible result for the space-like pion form factor.

description: We advocate and develop the use of the dreibein (and the metric) as prepotential for three-dimensional SO(3) Yang-Mills theory. Since the dreibein transforms homogeneously under gauge transformation, the metric is gauge invariant. For a generic gauge potential, there is a unique dreibein on fixing the boundary condition. Topologically non-trivial monopole configurations are given by conformally flat metrics, with scalar fields capturing the monopole centres. Our approach also provides an ansatz for the gauge potential covering the topological aspects.

description: Literacy development has been stifled through teaching approaches that suffocate learners in the classroom. This has been a trend the world over because of overreliance on traditional approaches to teaching literacy. The lack of progress in literacy development is manifested in the high failure and attrition rates in schools and universities. Against this background, there is a need to decolonize the way literacy development is promoted in the classroom. This research intervention employed learners’ written work, Department of Basic Education’s (DBE) curriculum documents such as textbooks, and semi structured interviews, Action Research and Reading to Learn (RtL) pedagogy to generate data. The paper illuminates the gains achieved through a teaching approach that is informed by Reading to Learn principles. As a decolonising pedagogy, the paper argues that RtL improved literacy development in a cohort of learners for three years leading up to Grade 12 in a township school in South Africa. Significant to the study is the extent to which RtL contributes significantly to the decolonisation of the formal education project. It exposes how the approved and traditional literacy practices continue to reproduce, and thus perpetuate, unequal relations in the classroom. The findings reinforce the argument that Reading to learn pedagogy accelerates literacy development towards improved epistemological access. The pedagogy is informed by scaffolding principles birthed by Brunner and Vygotsky, genre theory (Martin, 1985: Christie, 1990) and on the functional model of language developed by Halliday (1985). Importantly, a Systemic Functional Linguistics tool designed by (Rose, 2018) as an analytical framework is used in the paper. The study employs the mixed research approach. The emerging findings demonstrate the extent to which RtL pedagogy could be said to be contributing to the decolonisation project.

As a corollary, we can exhibit a new range of values for the parameters of Dirichlet random environments in dimension $d=2$ under which the corresponding random walk is ballistic.

description: While introductory electricity and magnetism (E&M) has been investigated for decades, research at the upper-division is relatively new. The University of Colorado has developed the Colorado Upper-Division Electrostatics (CUE) Diagnostic to test students' understanding of the content of the first semester of an upper-division E&M course. While the questions on the CUE cover many learning goals in an appropriate manner, we believe the rubric for the CUE is particularly aligned to the topics and methods of teaching at the University of Colorado. We suggest that changes to the rubric would allow for better assessment of a wider range of teaching schemes. As an example, we highlight one problem from the CUE involving the superposition principle. Using data from both Oregon State University and the University of Colorado, we discuss the limitations of the current rubric, compare results using a different analysis scheme, and discuss the implications for assessing students' understanding.

Abstract
Are microbial biosurfactants actually only surfactants?

description: The term biosurfactants refers to a complex mixture of metabolites with surface-active properties produced by specific microorganisms. However, nowadays trends moves towards isolation, screening and purifying single biocompatible, biodegradable biosurfactants with high commercialization potential. Current legislation limiting petrochemicals combined with environmentally concerned consumers did not only stimulate research and development but it also promoted large-scale production of this class of molecules. However, recent data recorded on single congeners question the actual pertinence of using the word ''biosurfactant'' associated to these molecules. By evaluating the accepted characteristics of surfactants and comparing them to the actual self-assembly and bulk properties in water of molecules traditionally called ''biosurfactants'', this opinion paper aims at showing that the term ''biosurfactant'' can be somewhat reductive when applied to specific individual compounds produced by fermentation. The use of a more generic term, like bioamphiphile could probably be more pertinent and appropriate for consideration in the future.

description: In this paper we obtain Gaussian-type lower bounds for the density of solutions to stochastic differential equations (SDEs) driven by a fractional Brownian motion with Hurst parameter $H$. In the one-dimensional case with additive noise, our study encompasses all parameters $H\in(0,1)$, while the multidimensional case is restricted to the case $H>1/2$. We rely on a mix of pathwise methods for stochastic differential equations and stochastic analysis tools.

Publisher: name: arXiv
Year: 2013
Subjects: subject: Computational Finance (q-fin.CP)
subject: FOS: Economics and business

description: We propose a hybrid tree-finite difference method in order to approximate the Heston model. We prove the convergence by embedding the procedure in a bivariate Markov chain and we study the convergence of European and American option prices. We finally provide numerical experiments that give accurate option prices in the Heston model, showing the reliability and the efficiency of the algorithm.

description: The multi-modal deep learning model based on the minimum bounding cube of the tumor edge had a good diagnostic value for the classification of breast mass lesions. The Sobel operator could effectively extract the lesion edge information and further increased the model performance in the classification task.

Demystifying Fraudulent Transactions and Illicit Nodes in the Bitcoin Network for Financial Forensics

Subjects: subject: Cryptography and Security (cs.CR)

subject: FOS: Computer and information sciences

description: Blockchain provides the unique and accountable channel for financial forensics by mining its open and immutable transaction data. A recent surge has been witnessed by training machine learning models with cryptocurrency transaction data for anomaly detection, such as money laundering and other fraudulent activities. This paper presents a holistic applied data science approach to fraud detection in the Bitcoin network with two original contributions. First, we contribute the Elliptic++ dataset, which extends the Elliptic transaction dataset to include over 822k Bitcoin wallet addresses (nodes), each with 56 features, and 1.27M temporal interactions. This enables both the detection of fraudulent transactions and the detection of illicit addresses (actors) in the Bitcoin network by leveraging four types of graph data: (i) the transaction-to-transaction graph, representing the money flow in the Bitcoin network, (ii) the address-to-address interaction graph, capturing the types of transaction flows between Bitcoin addresses, (iii) the address-transaction graph, representing the bi-directional money flow between addresses and transactions (BTC flow from input address to one or more transactions and BTC flow from a transaction to one or more output addresses), and (iv) the user entity graph, capturing clusters of Bitcoin addresses representing unique Bitcoin users. Second, we perform fraud detection tasks on all four graphs by using diverse machine learning algorithms. We show that adding enhanced features from the address-to-address and the address-transaction graphs not only assists in effectively detecting both illicit transactions and illicit addresses, but also assists in gaining in-depth understanding of the root cause of money laundering vulnerabilities in cryptocurrency transactions and the strategies for fraud detection and prevention.

Surface instabilities generated by a slider pulled across a granular bed

description: We report an instability of a slider slowly dragged at the surface of a granular bed in a quasistatic regime. The boat-shaped slider sits on the granular medium under its own weight and is free to translate vertically and to rotate around the pitch axis while a constant horizontal speed is imposed. For a wide range of parameters (mass, length, shape, velocity) a regular pattern of peaks and troughs spontaneously emerges as the slider travels forward. This instability is studied through experiments using a conveyor belt and by means of two-dimensional discrete elements method simulations. We show that the wavelength and amplitude of the pattern scale as the length of the slider. We also observe that the ripples disappear for low and high masses, indicating an optimal confining pressure. The effect of the shape, more specifically the inclination of the front spatula, is studied and found to drastically influence both the wavelength and the amplitude. Finally, we show that the mechanical details (friction, cohesion) of the contact point between the slider and the pulling device is critical and remains to be fully understood.
