    On bare masses in time-symmetric initial-value solutions for two black holes

    Full text link
    The Brill-Lindquist time-symmetric initial-value solution for two uncharged black holes is rederived using the Hamiltonian constraint equation with Dirac delta distributions as a source for the binary black-hole field. The bare masses of the Brill-Lindquist black holes are introduced in a way which is applied, after straightforward modification, to the Misner-Linquist binary black-hole solution.Comment: LaTeX, 4 page

    Excision boundary conditions for black hole initial data

    Get PDF
    We define and extensively test a set of boundary conditions that can be applied at black hole excision surfaces when the Hamiltonian and momentum constraints of general relativity are solved within the conformal thin-sandwich formalism. These boundary conditions have been designed to result in black holes that are in quasiequilibrium and are completely general in the sense that they can be applied with any conformal three-geometry and slicing condition. Furthermore, we show that they retain precisely the freedom to specify an arbitrary spin on each black hole. Interestingly, we have been unable to find a boundary condition on the lapse that can be derived from a quasiequilibrium condition. Rather, we find evidence that the lapse boundary condition is part of the initial temporal gauge choice. To test these boundary conditions, we have extensively explored the case of a single black hole and the case of a binary system of equal-mass black holes, including the computation of quasi-circular orbits and the determination of the inner-most stable circular orbit. Our tests show that the boundary conditions work well.Comment: 23 pages, 23 figures, revtex4, corrected typos, added reference, minor content changes including additional post-Newtonian comparison.

    IoTility:Architectural Requirements for Enabling Health IoT Ecosystems

    Get PDF
    The increasing ubiquity of the Internet of Things (IoT) has the potential to drastically alter the way healthcare systems are utilized at home or in a care environment. Smart things offer new ways to assist in general patient wellness, such as promoting an active and healthy lifestyle and simplifying treatment management. We believe smart health things bring new requirements not typically addressed in traditional IoT systems, and that an architecture targeting these devices must address such requirements to fully utilize their potential and safe usage. We believe such an architecture will help improve adoption and efficacy, closing gaps between the variety of emerging health IoT systems. In this paper, we present a number of requirements we consider integral to the continued expansion of the digital health IoT ecosystem (Health IoT). We consider the current landscape of IoT in relation to these requirements and present solutions that address two pressing requirements: 1) democratizing mobile health apps (giving users control and ownership over their app and data), and 2) making mobile apps act and behave like any other thing in an IoT. We present an implementation and evaluation of these Health IoT requirements to show how health-specific solutions can drive and influence the design of more generalized IoT architectures

    Transformation: The Bright Line Between Commercial Publicity Rights and the First Amendment

    The Right of Publicity provides to each and every person the right to use his or her persona for his or her benefit and provides a cause of action to stop the unauthorized use of that persona for commercial purposes. This right is one of the many provided by the laws of unfair competition. Infringement of this right has become a frequently pleaded count made by attorneys who are trying to protect their clients from the unauthorized use of the client’s persona for commercial purposes. While the genesis of the right has been commonly thought to be a splintering from the Right to Privacy, which in turn owes its birth to an article in a Harvard Law Journal in 1890, it may be more accurate to say that it has long been a common law right and has a common origin in trademark law as a commercial fraud. Originally, the Right of Publicity was thought to protect only the unauthorized use of a person’s name, likeness and image. Now, however, it is generally understood to encompass any personal attribute that identifies a particular person. For ease of discussion, that identity is referred to as the individual’s persona. The identifying attribute may be the individual’s name, likeness, image, voice, unique property identified with a person, or recognizable attire and “look,” unique to a person and by which he or she is known. The use of the Right of Publicity as a separate count in a complaint has become sufficiently common that it can now be said that it has come of age. Of course, there are still those who refuse to accept that the right grew in an appropriate fashion, and consider it to be like Topsy, arriving without any identifiable parentage. Whatever its origin, the reality is that it is here and that, in the last ten years, it has been separately pled and discussed in at least seventy-five different reported federal court cases
