Year: 2015

description: Enhancers are cis-regulatory elements of DNA that enhance the transcription of target genes and play a key role in development and diseases. Recently, a new class of enhancers named “super-enhancers” has been discovered, which refers to large clusters of transcriptional enhancers that can drive cell-type-specific gene expression and are crucial in cell identity. Many disease-associated sequence variations are enriched in these super-enhancer regions of disease-relevant cell types. Thus, super-enhancers can be used as potential biomarkers for disease diagnosis and therapeutics. Current studies have identified super-enhancers for more than 100 cell types in human and mouse. However, no centralized resource to integrate all these findings is available yet. We developed dbSUPER, the first extensive and interactive database of super-enhancers in mouse and human genome, with the primary goal of providing a resource for further study of transcriptional control of cell identity and disease by archiving computationally produced data. We provide an interactive data transfer platform to easily send the data to Galaxy, GREAT and Cistrome web servers for further downstream analysis. dbSUPER provides a responsive and user-friendly web interface to facilitate efficient and comprehensive searching and browsing. dbSUPER provides downloadable and exportable features in a variety of data formats, and can be visualized in UCSC genome browser while custom tracks will be added automatically. Further, dbSUPER lists genes associated with super-enhancers and links to various databases, including GeneCards, UniProt and Entrez. Our database also provides an overlap analysis tool, to check the overlap of user defined regions with the current database. Currently, our database contains 81,699 super-enhancers for 101 human and 25 mouse tissue/cell types. We believe, dbSUPER is a valuable resource for the bioinformatics and genetics research community.

description: The ability to control the frequency of an external-cavity diode laser (ECDL) is an essential component for undergraduate laboratories and atomic physics research. Typically the housing for the ECDL's diffraction grating and piezoelectric transducer is either purchased commercially or machined from metal. Here, we present an alternative to these commonly used options that utilizes 3D printing, a tool available in many physics departments. We characterize the performance of our ECDL system using atomic spectroscopy and self-heterodyne interferometry and show that it is sufficient for use in undergraduate spectroscopy experiments and a number of research applications where extremely narrow laser linewidths are not necessary. The performance and affordability of 3D-printed designs make them an appealing option for future use.

description: Segmentation of biomedical images can assist radiologists to make a better diagnosis and take decisions faster by helping in the detection of abnormalities, such as tumors. Manual or semi-automated segmentation, however, can be a time-consuming task. Most deep learning based automated segmentation methods are supervised and rely on manually segmented ground-truth. A possible solution for the problem would be an unsupervised deep learning based approach for automated segmentation, which this research work tries to address. We use a W-Net architecture and modified it, such that it can be applied to 3D volumes. In addition, to suppress noise in the segmentation we added attention gates to the skip connections. The loss for the segmentation output was calculated using soft N-Cuts and for the reconstruction output using SSIM. Conditional Random Fields were used as a post-processing step to fine-tune the results. The proposed method has shown promising results, with a dice coefficient of 0.88 for the liver segmentation compared against manual segmentation.

description: Lithium-sulfur (Li-S) batteries have become one of the most attractive alternatives over conventional Li-ion batteries due to their high theoretical specific energy density (2500 Wh/kg for Li-S vs. $\sim$250 Wh/kg for Li-ion). Accurate state estimation in Li-S batteries is urgently needed for safe and efficient operation. To the best of the authors' knowledge, electrochemical model-based observers have not been reported for Li-S batteries, primarily due to the complex dynamics that make state observer design a challenging problem. In this work, we demonstrate a state estimation scheme based on a zero-dimensional electrochemical model for Li-S batteries. The nonlinear differential-algebraic equation (DAE) model is incorporated into an extend Kalman filter. This observer design estimates both differential and algebraic states that represent the dynamic behavior inside the cell, from voltage and current measurements only. The effectiveness of the proposed estimation algorithm is illustrated by numerical simulation results. Our study unlocks how an electrochemical model can be utilized for practical state estimation of Li-S batteries.
Kinematics in Matrix Gravity

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We develop the kinematics in Matrix Gravity, which is a modified theory of gravity obtained by a non-commutative deformation of General Relativity. In this model the usual interpretation of gravity as Riemannian geometry is replaced by a new kind of geometry, which is equivalent to a collection of Finsler geometries with several Finsler metrics depending both on the position and on the velocity. As a result the Riemannian geodesic flow is replaced by a collection of Finsler flows. This naturally leads to a model in which a particle is described by several mass parameters. If these mass parameters are different then the equivalence principle is violated. In the non-relativistic limit this also leads to corrections to the Newton's gravitational potential. We find the first and second order corrections to the usual Riemannian geodesic flow and evaluate the anomalous nongeodesic acceleration in a particular case of static spherically symmetric background.

title: Strategies for template-free direct biometric encryption using voice based features
Creators: name: Atah, Alewo Joshua
Publisher: name: University of Kent
Year: 2021

description: Current biometric systems references information stored on templates and it possess major drawbacks in their inability, if lost or stolen, to be revoked and re-issued as would be the case with passwords. Thus, once a biometric source has been compromised, the owner of the biometric, as well as the data protected by the biometric, is compromised for life. This research investigates the potential of the voice modality for employment in a template-!ree biometric system. which requires storage of neither hiometric templates nor encryption keys. It 'rl'orks by directly encrypting the biometric data provided by the human voice and therefore eliminates the need for storing templates used for data validation, and thus increasing the security of the system. The research also introduces feature concatenation as a novel method of combining the binary information from the feature sets and also introduces five new revocation strategies based on the template-free method The promising results allow us to conclude that voice may potentially form the basis for a practical template-free biometric system.

description: Light bridges (LBs) are relatively bright structures that divide sunspot umbrae into two or more parts. Chromospheric LBs are known to be associated with various activities including fan-shaped jet-like ejections and brightenings. Although magnetic reconnection is frequently suggested to be responsible for such activities, not many studies present firm evidence to support the scenario. We carry out magnetic field measurements and imaging spectroscopy of a LB where fan-shaped jet-like ejections occur with co-spatial brightenings at their footpoints. We study LB fine structure and magnetic field changes using TiO images, Near-InfraRed Imaging Spectropolarimeter, and Halpha data taken by the 1.6~m Goode Solar Telescope. We detect magnetic flux emergence in the LB that is of opposite polarity to that of the sunspot. The new magnetic flux cancels with the pre-existing flux at a rate of 5.6x10^18 Mx/hr. Both the recurrent jet-like ejections and their base brightenings are initiated at the vicinity of the magnetic flux cancellation, and show apparent horizontal extension along the LB at a projected speed of up to 18.4km/s to form a fan-shaped appearance. Based on these observations, we suggest that the fan-shaped ejections may have resulted from slipping reconnection between the new flux emerging in the LB and the ambient sunspot field.

description: The purpose of this study was to determine what factors influence African American male students to leave high school without earning a diploma.  Twenty students were randomly selected into four categories: five ninth, five tenth, five eleventh, and five twelfth grade students.  Each student completed an in-depth questionnaire containing objective questions relating to educational, social, and socioeconomic factors that may influence black male students to withdraw from high school. Each respondent response was tallied and the data was placed on a table according to each grade level. The questionnaire did not reveal any specific educational, social and/or socioeconomic factors that may influence the twenty black male students'  decision to leave high school without earning a diploma. Research in this area
should continue as there is much more information available regarding factors that may influence black male students to leave high school without earning their diploma.

description: We have investigated the dynamics of bound particles in multilevel current-carrying quantum dots. We look specifically in the regime of resonant tunnelling transport, where several channels are available for transport. Through a non-Markovian formalism under the Born approximation, we investigate the real-time evolution of the confined particles including transport-induced decoherence and relaxation. In the case of a coherent superposition between states with different particle number, we find that a Fock-space coherence may be preserved even in the presence of tunneling into and out of the dot. Real-time results are presented for various asymmetries of tunneling rates into different orbitals.

description: The purpose of this study was to determine whether or not the instructional
strategy “Word Talks” has a positive impact on DIBELS composite scores. The study
was based on a group of 21 students, 5 to 7 years of age. This particular group of 21
Kindergartners was comprised of students from diverse socioeconomic and cultural
backgrounds. This study focused on participation, student connections, phonemic
awareness and phonics. Academic progress was assessed based on a pre-assessment,
which took place in January compared to a post-assessment conducted three months later
in April. The assessment measurement tool was DIBELS (Dynamic Indicator of Basic
Early Literacy Skills). Students received explicit instruction focused on phonemic awareness and
phonics conversations. The researcher recorded student responses to provide a visual for
letter to sound correspondences. The group participating in the study made connections
to a word family by changing beginning sounds, ending sounds, and or vowel sounds.
Based on one specific word family, students provided a new word (real or nonsense). Upon completing the study, the null hypothesis was rejected. The standard
deviation was equal to or less than .02. The results demonstrated that “Word Talks”
increased composite DIBELS scores.
title: SME market orientation: relationship with supermarket loyalty card data
Creators: name: Donnelly, Christina
Publisher: name: University of Kent
Year: 2021

description: Market oriented organisations are firms which are well informed about the market in which they operate in, and utilise this market information and knowledge to create competitive advantage. This is particularly important for small to medium-sized enterprises (SMEs). In Northern Ireland (NI), particular focus has been placed on the agri-food SME sector and the need for a constant flow of market information, in what has become an extremely competitive and evolving food and drink market. This study sought to explore the relationship between SME market orientation (MO) and formalised supermarket loyalty card data (SLCD), within the NI agri-food context. This is the first time that SME agri-food firms have received free access and analysis of SLCD. The research design was qualitative and required a six month longitudinal inquiry utilising an in-depth interviewing process with seven agri-food SME case firms, before and after exposure to SLCD. The study made a number of contributions to knowledge, practice and policy. Findings confirmed that SMEs do possess some level of MO, practicing informal, unstructured and haphazard marketing due to their small scale and the central role of the generalist owner/manager. However, post exposure findings confirmed that the SME agri-food cases did relate to SLCD, with owner/managers enhancing understanding of the consumer, increasing confidence in data use and validating decision making with SLCD. In effect SLCD facilitated the management of risk for the SME agri-food firm. During the initial stages of inquiry, other strategic orientations emerged, in the form of Entrepreneurship Orientation (EO) and the capacity to innovate. These concepts both supported the current MO of the SME, facilitating enhanced understanding and utilisation of SLCD. A further contribution was the recognition of the role of the owner/manager within the relationship and the need for the action research approach in the delivery of SLCD to the agri-food SMEs. Key findings suggest that future acquisition of SLCD is necessary for SMEs within the food industry, but dissemination and utilisation requires future support by government and industry bodies. To facilitate this, policy makers should review existing policies and practices, to support agri-food SME development through the continual flow of market information and analytical assistance on a partnership basis.

description: In this paper, we first present a multiple-relaxation-time lattice Boltzmann (MRT-LB) model for one-dimensional diffusion equation where the D1Q3 (three discrete velocities in one-dimensional space) lattice structure is considered. Then through the theoretical analysis, we derive an explicit four-level finite-difference scheme from this MRT-LB model. The results show that the four-level finite-difference scheme is unconditionally stable, and through adjusting the weight coefficient $ω_{0}$ and the relaxation parameters $s_1$ and $s_2$ corresponding to the first and second moments, it can also have a sixth-order accuracy in space. Finally, we also test the four-level finite-difference scheme through some numerical simulations, and find that the numerical results are consistent with our theoretical analysis.

description: The experimental status of the pentaquark searches is briefly reviewed. Recent null results by the CLAS collaboration are commented, and new strong evidence of a very narrow Theta+ resonance by the DIANA collaboration is presented. On the theory side, I revisit the argument against the existence of the pentaquark -- that of Callan and Klebanov -- and show that actually a strong resonance is predicted in that approach, however its width is grossly overestimated. A recent calculation gives 2 MeV for the pentaquark width, and this number is probably still an upper bound.

description: This is the third paper of a series of papers where we explore the evolution of iron-rich ejecta from quark-novae. In the first paper, we explored the case where a quark-nova ejecta forms a degenerate shell, supported by the star's magnetic field, with applications to SGRs. In the second paper we considered the case where the ejecta would have sufficient angular momentum to form a degenerate Keplerian torus and applied such a system to two AXPs, namely 1E2259 + 586 and 4U0142 + 615. Here we explore the late evolution of the degenerate torus and find that it can remain unchanged for $\sim 10^{6}$ years before it becomes non-degenerate. This transition from a degenerate torus (accretion dominated) to a non-degenerate disk (no accretion), occurs about $10^{6}$ years following the quark-nova, and exhibits features that are reminiscent of observed properties of RRATs. Using this model, we can account for the duration of both the radio bursts and the quiet phase, as well as the observed radio flux from RRATs. The unique on and off activity of the radio pulsar PSR B1931 + 24 is similar to that of "old RRATs" in our model. For old RRATs, in our model, the spin-down rate during the radio loud phase is about a factor 1.6 larger than when it is quiet, remarkably similar to what has been measured for PSR B1931 + 24. We discuss a connection between XDINs and RRATs and argue that some XDINs may be ``dead RRATs'' that have already consumed their non-degenerate disk.

description: Before the arrival of Bantu languages, southern Africa was dominated by speakers of Khoisan languages, a group of three unrelated language families that share the typologically highly unusual feature of using click phonemes. While nowadays Khoisan languages are severely endangered, earlier contacts between Bantu speakers and speakers of Khoisan languages must have been fairly extensive and have led to lexical, phonological and morphological changes. This paper aims at investigating the extent of Khoisan influence in various southern African Bantu languages and at reconstructing the different sociocultural contact situations in which these changes arose.

description: Young massive star-forming regions are known to produce hot molecular gas cores (HMCs) with a rich chemistry. While this chemistry is interesting in itself, it also allows to investigate important physical parameters. I will present recent results obtained with high-angular-resolution interferometers disentangling the small-scale structure and complexity of various molecular gas components. Early attempts to develop a chemical evolutionary sequence are discussed. Furthermore, I will outline the difficulty to isolate the right molecular lines capable to unambiguously trace potential massive accretion disks.

description: The purpose of this study was to determine the impact of ClassDojo and Go Noodle exercises on off-task and behavioral disruptions in a third grade classroom. This study utilized a pre/post quasi-experimental design that compared data from November, 2014, to data from March, 2015. The measurement tool was a computer program called ClassDojo that allowed instructors to record student behavioral and off-task disruptions. Analysis of the results revealed that Go Noodle and ClassDojo did not affect the behavioral and off-task disruptions of students in a third grade classroom. In conclusion, more research needs to be conducted to determine whether these interventions could have a positive impact on the behavioral and off-task disruptions of students.
title: Sexuality and intimate relationships for people with learning disability in Malta: realities and potentials
Creators: name: Azzopardi Lane, Claire Lucille
Publisher: name: University of Kent
Year: 2021

description: Sexuality is an area in which people with learning disability are disabled by social attitudes. Stereotypical views about the sexuality of people with learning disability range from asexuality, implying that they have no erotic or romantic inclinations, to hyper-sexuality which reinforces institutionalized sex segregation through the process of social exclusion. In Malta all these influences contribute to hinder the rights and the quality of life of people with learning disability. The theory of the social model of disability underpins the research aims, while reflecting discourses of equality and rights. The research aims at giving a better understanding of the sexual lives of people with learning disability in a Maltese context, whilst eliciting the opinions and beliefs of people with learning disability themselves, their parents and their service providers. Qualitative data, collected from people with learning disability, their parents and service providers is interpreted using phenomenological analysis. A sex education intervention pilot project is also run as part of the research, being informed by the findings of the same research. Findings identify ideologies, highlight missing structures and illustrate feasible future strategies. They reveal a lack of community support and emphasise the need of platforms where people with learning disability can form and maintain friendships and relationships. The dearth of any adequate form of sex education currently available for people with learning disability across Malta as well as the lacuna in policies related to sexuality, and particularly referring to the sexuality of people with learning disability is also uncovered. Recommendations reflecting findings from the main research study and the pilot project mainly target the necessity of sex education, policies and procedures surrounding sexuality in the context of people with learning disability in services across the islands.

title: British tank production, 1934-1945
Creators: name: Coombs, Benjamin
Publisher: name: University of Kent
Year: 2021

description: This thesis examines the governmental, industrial and strategic factors that influenced British tank production from 1934 until 1945 against the wider context of the British war economy arid the tank programmes of Canada and the United States. The changing organisational structure of controlling the British tank programme has been reviewed alongside the mutual considerations of war planning for the armed forces generally. A central theme of this research has been to provide a history of war production by highlighting the specific demands placed upon individual firms against the different pressures of war, such as the threat and effects of bombing and shortages of skilled labour and components. This study has shown that the priority for aircraft production, together with the immediate requirement to provide large numbers of tanks to the army during the first half of the war, meant that the initial problems associated with British tank design were unavoidable. The transformation from quantity to quality tank output during the second half of the war was achieved by the introduction of new tank designs, improvements in assembly efficiency, and by accepting greater numbers of Lend-Lease tanks to supplement General Staff requirements. This reliance upon American armour originated from the first orders during 1940 until the end of the war, although British over dependency was demonstrated when both nations contracted their respective tank programmes prematurely during 1944. The Canadian tank programme greatly assisted British efforts to supply the Russian authorities with the preferred Valentine tank, which was necessary to achieve their operational doctrine of standardised equipment. Finally, the post-war British tank programme inirrored the pre-war arrangement of Vickers-Armstrongs and the new state controlled Royal Tank Arsenal, whilst the civilian tank firms transferred to their core industries to supply the re-emerging peacetime markets.
The Energetics of a Flaring Solar Active Region, and Observed Flare Statistics

description: A stochastic model for the energy of a flaring solar active region is presented, generalising and extending the approach of Wheatland & Glukhov (1998). The probability distribution for the free energy of an active region is described by the solution to a master equation involving deterministic energy input and random jump transitions downwards in energy (solar flares). It is shown how two observable distributions, the flare frequency-energy distribution and the flare waiting-time distribution, may be derived from the steady-state solution to the master equation, for given choices for the energy input and for the rates of flare transitions. An efficient method of numerical solution of the steady-state master equation is presented. Solutions appropriate for flaring, involving a constant rate of energy input and power-law distributed jump transition rates, are numerically investigated. The flare-like solutions exhibit power-law flare frequency-energy distributions below a high energy rollover, set by the largest energy the active region is likely to have. The solutions also exhibit approximately exponential (i.e. Poisson) waiting-time distributions, despite the rate of flaring depending on the free energy of the system.

description: Active plasma lenses are compact devices developed as a promising beam-focusing alternative for charged particle beams, capable of short focal lengths for high-energy beams. We have previously shown that linear magnetic fields with gradients of around 0.3 kT/m can be achieved in argon-filled plasma lenses that preserve beam emittance [C.A. Lindstrøm et al., Phys. Rev. Lett. 121, 194801 (2018)]. Here we show that with argon in a 500 μm diameter capillary, the fields are still linear with a focusing gradient of 3.6 kT/m, which is an order of magnitude higher than the gradients of quadrupole magnets. The current pulses that generate the magnetic field are provided by compact Marx banks, and are highly repeatable. These results establish active plasma lenses as an ideal device for pulsed particle beam applications requiring very high focusing gradients that are uniform throughout the lens aperture.

description: Abundance observations indicate the presence of rapid-neutron capture (i.e., r-process) elements in old Galactic halo and globular cluster stars. These observations provide insight into the nature of the earliest generations of stars in the Galaxy -- the progenitors of the halo stars -- responsible for neutron-capture synthesis of the heavy elements. The large star-to-star scatter observed in the abundances of neutron-capture element/iron ratios at low metallicities -- which diminishes with increasing metallicity or [Fe/H] -- suggests the formation of these heavy elements (presumably from certain types of supernovae) was rare in the early Galaxy. The stellar abundances also indicate a change from the r-process to the slow neutron capture (i.e., s-) process at higher metallicities in the Galaxy and provide insight into Galactic chemical evolution. Finally, the detection of thorium and uranium in halo and globular cluster stars offers an independent age-dating technique that can put lower limits on the age of the Galaxy, and hence the Universe.

description: The purpose of the study was to determine whether the reading comprehension skill of
fourth grade students identified as average readers improves when they sketch in
response to reading a text before answering comprehension questions compared to simply
reading and responding. A quasi-experimental design was used. The participants in this
study were 12 fourth grade students from a public elementary school in Anne Arundel
County. Of the 12 students, 6 were males and 6 were females. The Comprehensive
Quality Rating Tool and the fourth grade Common Core Informational/Explanatory Text
Based Rubric were both used to measure the students’ answers to the comprehension
questions. The Wilcoxon Signed Rank Test, a non-parametric test, was used to compare
median scores obtained under treatment conditions across 10 writing samples with those
obtained under control conditions (same 10 writing samples). Median rubric scores were
not significantly different under the two different conditions. The hypothesis that the
comprehension of fourth grade students prompted to draw in response to reading nonfiction
text will not be different from their comprehension without the prompt was not
rejected. Recommendations for future research include using students who are below
grade level with below level text, to have students draw throughout reading rather than
drawing right before answering a question, to further explore the gender differences in
this matter, and to explore different genres of text.

description: Introduction: For COVID-19 patients accurate prediction of disease severity and mortality risk would greatly improve care delivery and resource allocation. There are many patient-related factors, such as pre-existing comorbidities that affect disease severity. Since rapid automated profiling of peripheral blood samples is widely available, we investigated how such data from the peripheral blood of COVID-19 patients might be used to predict clinical outcomes. Methods: We thus investigated such clinical datasets from COVID-19 patients with known outcomes by combining statistical comparison and correlation methods with machine learning algorithms; the latter included decision tree, random forest, variants of gradient boosting machine, support vector machine, K-nearest neighbour and deep learning methods. Results: Our work revealed several clinical parameters measurable in blood samples, which discriminated between healthy people and COVID-19 positive patients and showed predictive value for later severity of COVID-19 symptoms. We thus developed a number of analytic methods that showed accuracy and precision for disease severity and mortality outcome predictions that were above 90%. Conclusions: In sum, we developed methodologies to analyse patient routine clinical data which enables more accurate prediction of COVID-19 patient outcomes. This type of approaches could, by employing standard hospital laboratory analyses of patient blood, be utilised to identify, COVID-19 patients at high risk of mortality and so enable their treatment to be optimised.

The lipid bilayer at the mesoscale: a physical continuum model

description: We study a continuum model of the lipid bilayer based on minimizing the free energy of a mixture of water and lipid molecules. This paper extends previous work by Blom & Peletier (2004) in the following ways. (a) It formulates a more physical model of the hydrophobic effect to facilitate connections with microscale simulations. (b) It clarifies the meaning of the model parameters. (c) It outlines a method for determining parameter values so that physically-realistic bilayer density profiles can be obtained, for example for use in macroscale simulations. Points (a)-(c) suggest that the model has potential to robustly connect some micro- and macroscale levels of multiscale blood flow simulations. The mathematical modelling in point (a) is based upon a consideration of the underlying physics of inter-molecular forces. The governing equations thus obtained are minimized by gradient flows via a novel numerical approach; this enables point (b). The numerical results are shown to behave physically in terms of the effect of background concentration, in contrast to the earlier model which is shown here to not display the expected behaviour. A "short-tail" approximation of the lipid molecules also gives an analytical tool which yields critical values of some parameters under certain conditions. Point (c) involves the first quantitative comparison of the numerical data with physical experimental results.
