This paper presents a novel approach for simulating incompressible two-phase flows by combining a conservative level set technique and the ghost-fluid method. Following the ideas of Olsson and Kreiss (2005), the liquid-gas interface is localized using a hyperbolic tangent level set that is transported and reinitialized using fully conservative numerical schemes. Mass conservation issues are gre...
Performance Limits of Low‐Temperature, Continuous Locomotion Are Exceeded When Locomotion Is Intermittent in the Ghost Crab Author(s): Randi B. Weinstein and Robert J. Full Source: Physiological Zoology, Vol. 71, No. 3 (May/June 1998), pp. 274-284 Published by: The University of Chicago Press.

Properly assigning authorship of academic papers is often an ethical challenge. Through a hypothetical case study, the authors examine some of the potential ethical issues involved in determining who should and should not be listed as an author: the problems of honorary authorship, coerced authorship, and ghost authorship, as well as the question of how to order authors. Guidelines for avoiding...
در این پژوهش جریان سیال درون مجرا به صورت ضربانی و با دیوار هایپوالاستیک با استفاده از روش wcsph مورد بررسی قرار گرفته است. در این روش سیال غیرقابل تراکم با تراکم پذیری اندک در نظر گرفته شده و برای محاسبه ی فشار از معادله ی حالت استفاده شده است. با توجه به مشکلات این روش در اعمال شرایط مرزی، در راستای رفع آن از ذراتghost برای مرزها استفاده شده و با توجه به شرط مرزی متناوب برای خروجی، نیرو، به م...
Exhaustive ghost solutions to Einstein-Weyl equations for two dimensional spacetimes are obtained, where the ghost neutrinos propagate in the background spacetime, but do not influence the background spacetime due to the vanishing stress-energy-momentum tensor for the ghost neutrinos. Especially, those non-trivial ghost solutions provide a counterexample to the traditional claim that the Einste...
Color matrix elements of the ghost triangle diagram that appears in the triple gluon vertex and the ghost-ghost-gluon triangle diagram that appears in the ghost-gluon-ghost vertex are calculated. The ghost-ghost-gluon triangle contains a loop consisting of two color diagonal ghost and one gluon and a loop consisting of two color antisymmetric ghost and one gluon. Consequently the pQCD argument ...
We define a notion of ghost centre of a Lie superalgebra g = g0 ⊕ g1 which is a sum of invariants with respect to the usual adjoint action (centre) and invariants with respect to a twisted adjoint action (“anticentre”). We calculate the anticentre in the case when the top external degree of g1 is a trivial g0-module. We describe the Harish-Chandra projection of the ghost centre for basic classi...

In the beginning of 1998 Gerard van der Geer and Ren e Schoof posted a beautiful preprint (cf. [2]). Among other things in this preprint they de ned exactly h(L) for Arakelov line bundles L on an \arithmetic curve", i.e. a number eld. The main advantage of their de nition was that they got an exact analog of the Riemann-Roch formula h(L) h(K L) = degL+1 g: Before that h(L) was de ned as an inte...
