  1. Imaging the Developing Heart: Synchronized Timelapse Microscopy During Developmental Changes

    Nelson, Carl J.; Buckley, Charlotte; Mullins, John J.; Denvir, Martin A.; Taylor, Jonathan
    How do you use imaging to analyse the development of the heart, which not only changes shape but also undergoes constant, high-speed, quasi-periodic changes? We have integrated ideas from prospective and retrospective optical gating to capture long-term, phase-locked developmental time-lapse videos. In this paper we demonstrate the success of this approach over a key developmental time period: heart looping, where large changes in heart shape prevent previous prospective gating approaches from capturing phase- locked videos. We use the comparison with other approaches to in vivo heart imaging to highlight the importance of collecting the most appropriate data for the biological...

  2. GRAM: Global Research Activity Map

    Burd, Randy; Espy, Kimberly Andrews; Hossain, Md Iqbal; Kobourov, Stephen; Merchant, Nirav; Purchase, Helen
    The Global Research Activity Map (GRAM) is an interactive web-based system for visualizing and analyzing worldwide scholarship activity as represented by research topics. The underlying data for GRAM is obtained from Google Scholar academic research profiles and is used to create a weighted topic graph. Nodes correspond to self-reported research topics and edges indicate co-occurring topics in the profiles. The GRAM system supports map-based interactive features, including semantic zooming, panning, and searching. Map overlays can be used to compare human resource investment, displayed as the relative number of active researchers in particular topic areas, as well scholarly output in terms...

  3. Optimization Based Self-localization for IoT Wireless Sensor Networks

    Beuchat, Paul; Hesse, Henrik; Domahidi, Alexander; Lygeros, John
    In this paper we propose an embedded optimization framework for the simultaneous self-localization of all sensors in wireless sensor networks making use of range measurements from ultra-wideband (UWB) signals. Low-power UWB radios, which provide time-of-arrival measurements with decimeter accuracy over large distances, have been increasingly envisioned for realtime localization of IoT devices in GPS-denied environments and large sensor networks. In this work, we therefore explore different non-linear least-squares optimization problems to formulate the localization task based on UWB range measurements. We solve the resulting optimization problems directly using non-linear-programming algorithms that guarantee convergence to locally optimal solutions. This optimization framework...

  4. Financial Investment and Economic Policy Uncertainty in the UK

    Azqueta-Gavaldon, Andres
    UK based financial firms following Brexit reported net disinvestment of 15 billion pounds. This was the fifth time financial disinvestment occurred since the production of this data: 1987. Parallel to this event, Economic Policy Uncertainty (EPU) in the UK experienced its biggest rise during Brexit June 2016. This note studies the relationship between EPU and its particular components and financial investment. I find that overall EPU and specifically fiscal policy, monetary policy, geopolitical, regulation and liquidity uncertainty have the highest negative sensitivity to financial investment.

  7. Analysis of Dead-time Harmonics in Single-phase Transformerless Full-bridge PV Inverters

    Yang, Yongheng; Zhou, Keliang; Blaabjerg, Frede
    A short period, called dead time, is usually implemented (e.g., through adding extra hardware in gate drivers or modifying pulse-width modulation schemes) for voltage source inverters to prevent shoot-through incidents. Clearly, larger dead time provides more safety, but may also degrade the injected currents from inverters. It thus requires sophisticated compensation schemes to meet certain stringent standards. For single-phase transformerless full-bridge PV inverters, different modulation schemes can be employed to suppress leakage currents, which in return may affect the distribution of the dead time harmonics. Thus, this drives the analysis of dead time harmonics in single-phase transformerless full-bridge inverters considering...

  9. Vandalism on Collaborative Web Communities: An Exploration of Editorial Behaviour in Wikipedia

    Alkharashi, Abdulwhab; Jose, Joemon
    Modern online discussion communities allow people to contribute, sometimes anonymously. Such flexibility sometimes threatens the reputation and reliability of community-owned resources. Such flexibility is understandable, however, they engender threats to the reputation and reliability in collective goods. Since not a lot of previous work addressed these issues it is important to study the aforementioned issues to build an innate understanding of recent ongoing vandalism of Wikipedia pages and ways to preventing those. In this study, we consider the type of activity that the anonymous users carry out on Wikipedia and also contemplate how others react to their activities. In particular, we...

  17. Truncated Channel Inversion Power Control for the Uplink of mmWave Cellular Networks

    Onireti, Oluwakayode; Imran, Muhammad Ali
    In this paper, using the stochastic geometry, we develop a tractable uplink modeling paradigm for the outage probability of millimeter wave (mmWave) cellular networks. Our model takes account of the maximum power limitation and the per-user equipment (UE) power control as well as the effect of blockages. More specifically, each UE, which could be in line-ofsight (LOS) or non-LOS to its serving base station (BS), controls its transmit power such that the received signal power at its serving BS is equal to a predefined threshold. Hence, a truncated channel inversion power control is implemented for the uplink of the mmWave cellular network. We derive expressions for the truncated outage probability and...

  18. Molecular Based Flash Cell for Low Power Flash Application: Optimization and Variability Evaluation

    Georgiev, Vihar P.; Vila-Nadal, Laia; Cronin, Leroy; Asenov, Asen
    The field of molecular electronics continues to spur interest in the quest for miniaturization and reduction of operational power of electron devices. Most of the systems described in the literature are based on organic molecules, such as benzene, ferrocene and fullerenes. However, the use of inorganic molecules known as polyoxometalates (POMs) (see Fig.l and Fig.2) could offer several important advantages over the conventional and organic based devices. Our present work shows that POMs are more compatible with existing CMOS processes than organic molecules and they can replace the polysilicon floating gate in contemporary flash cell devices [2]. The interest in...

  19. Characterising the forming mechanics of pre-consolidated nylon-carbon composite

    Harrison, Philip; Fernandez Alvarez, Marcos; Correia, Nuno; Mimoso, Pedro; Cristovao, Claudia; Gomes, Rui
    Preliminary bending and shear tests are performed on a nylon-carbon fibre pre-consolidated cross-ply 0/90/90/0 laminate. The aim is to produce data for use in macro-scale forming simulations. A novel variation on the usual uniaxial bias extension tests is devised. The modifications are designed to create a well-defined boundary condition at the extremities of the test specimen while avoiding transverse squeeze flows due to clamping pressure and undesirable temperature gradients across the test specimen. A variant of the cantilever test is also developed to characterise the temperature-dependent flexural rigidity of the composite as a function of temperature. The cantilever set-up is...

  20. Automated verification of concurrent stochastic games

    Kwiatkowska, Marta; Norman, Gethin; Parker, David; Santos, Gabriel
    We present automatic verifcation techniques for concurrent stochastic multi-player games (CSGs) with rewards. To express properties of such models, we adapt the temporal logic rPATL (probabilistic alternating-time temporal logic with rewards), originally introduced for the simpler model of turn-based games, which enables quantitative reasoning about the ability of coalitions of players to achieve goals related to the probability of an event or reward measures. We propose and implement a modelling approach and model checking algorithms for property verifcation and strategy synthesis of CSGs, as an extension of PRISMgames. We evaluate the performance, scalability and applicability of our techniques on case studies from domains such as security, networks and finance, showing that...
