    The QSNET consortium is building a UK network of next-generation atomic and molecular clocks that will achieve unprecedented sensitivity in testing variations of the fine structure constant, α, and the electron-to-proton mass ratio, μ. This in turn will provide more stringent constraints on a wide range of fundamental and phenomenological theories beyond the Standard Model and on dark matter models.

    The Software-Defined Networking (SDN) technology is a network management method that allows dynamic, programmatically efficient network planning to improve its performance and monitoring. Given that SDN at each passing day becomes more prominent, a framework that can ensure reliable communication and a global state among devices become more important. We propose a state consistency framework that leverages a state machine abstraction using network updates among adjacent switches through packet piggybacking. We also use a moving average that when a condition is met, P4's packet cloning is triggered, hence ensuring that all packets arrive at their destination in the presence of link failures.

    Several members of SEG (Matt Gross, Phil Johnstone, Florian Kern, Gordon MacKerron, and Andy Stirling) have participated in a written response to the Department of Energy and Climate Change’s (DECC) consultation of the siting process for a Geological Disposal Facility (GDF) for nuclear waste. This consultation follows the rejection by Cumbria County Council earlier this year to hosting a Geological Disposal Facility. The government have therefore gone back to the national level to find a suitable location, and the issue remains a multifaceted and controversial one. Matt Gross and Phil Johnstone also represented SEG at the one day consultation on the same issue run by DECC at Centre Hall, Westminster, involving several round-table discussions with civil service, nuclear regulators, and local politicians on the various issues surrounding the siting of a GDF.

    An Ion Trap 1 comprises a magnetic field generator 2 arranged to generate a magnetic field and an array 3 of electrodes arranged to generate an electrostatic field including a turning point in electrical potential at a location where the magnetic field is substantially homogenous. The array of electrodes 3 is planar and parallel to the direction of the magnetic field at the location, with the result that the ion trap can be described as a coplanar waveguide Penning trap. \ud \ud 15 Claims, 18 Drawing Sheets

    In-vehicle network monitoring is one of the important elements in vehicular network management and security. Most of the existing network monitoring approaches rely on measuring every part of the network. Such approaches overburden the network by transmitting active probes. In this work, we propose a new in-vehicle network monitoring approach that benefits from network tomography and the advances in deep learning to infer the network delay performance. Specifically, the available measurements can be used to estimate the performance of the remaining network where direct measurements cannot be applied. Performance evaluation has been conducted using in-vehicle network simulation with different TSN (Time-Sensitive Network) traffics and the proposed monitoring approach shows the delay estimation accuracy of up to 99%.

    We discuss three cases of transformative creative practice that aim to address large-scale societal issues related to the climate emergency by taking a series of interconnected, small-scale actions. Drawing on our first-hand perspectives, we reflect on how the cases address such issues by proliferating across different social contexts and supporting creative engagements of diverse stakeholders. We offer this empirical reflection at a time of rapid social and ecological change that has affected all life on the planet. Eco-social challenges and structural inequalities caused by shifts in global economic, political and technological power require new approaches and transformative actions to stabilize and restore ecosystems on which life depends. Our research shows that creative practice in art and design has a critical role to play in these processes of transformation. By discussing the opportunities and challenges encountered by our three cases within their transformative efforts and analyzing how they proliferate across diverse scales, we aim to expand the emerging scholarship on the transformative potential of creative practice.

    5G heterogeneous wireless networks are believed to be an emerging and promising solution to meet growing demands posed by various vehicular telematics and infotainment applications. However, there are some challenges in designing a feasible and efficient 5G heterogeneous wireless network for pervasive vehicular connectivity, such as the complexity in the large-scale heterogeneous architecture and the dynamic nature of vehicular applications. In this paper, we propose an intelligent 5G heterogeneous wireless network architecture which includes a reinforcement learning (Q-learning)-based Dedicated Short Range Communication (DSRC) for Vehicle-to-Vehicle (V2V) and millimeter wave (mmWave) for Vehicle-to-Infrastructure (V2I) communications. Based on our findings, the goal is to develop essential vehicular connectivity management components and a situationally-aware central intelligent wireless optimizing unit to coordinate network selection for optimal vertical handoff decisions among these heterogeneous access radios. Performance evaluation supplemented by large scale simulation and field test are also provided to show our efforts in delivering our commitment.

    The exploitation of syntactic graphs (SyGs) as a word's context has been shown to be beneficial for distributional semantic models (DSMs), both at the level of individual word representations and in deriving phrasal representations via composition. However, notwithstanding the potential performance benefit, the syntactically-aware DSMs proposed to date have huge numbers of parameters (compared to conventional DSMs) and suffer from data sparsity. Furthermore, the encoding of the SyG links (i.e., the syntactic relations) has been largely limited to linear maps. The knowledge graphs' literature, on the other hand, has proposed light-weight models employing different geometric transformations (GTs) to encode edges in a knowledge graph (KG). Our work explores the possibility of adopting this family of models to encode SyGs. Furthermore, we investigate which GT better encodes syntactic relations, so that these representations can be used to enhance phrase-level composition via syntactic contextualisation.

    SOGICA (Sexual Orientation and Gender Identity Claims of Asylum: A European Human Rights Challenge) is a four-year (2016-2020)research project funded by the European Research Council (ERC)that explores the social and legal experiences of individuals across Europe claiming international protection on the basis of their sexual orientation or gender identity (SOGI). It is led by Professor Nuno Ferreira and a team of researchers at the University of Sussex who are Dr Carmelo Danisi, Dr Moira Dustin and Dr Nina Held.\ud \ud We thank the Committee members for this opportunity to contribute. We are pleased to see that the Sub-Committee has received submissions by experts in the broad field of asylum,including the Immigration Law Practitioners Association, as well as respected academic colleagues. Our research addresses the needs of a group of people who are often marginalized but who face particular problems reaching Europe and claiming asylum in member states.
