Equilibria of binary neutron stars in close circular orbits are computed numerically in a waveless formulation: the full Einstein-relativistic-Euler system is solved on an initial hypersurface to obtain an asymptotically flat form of the 4-metric and an extrinsic curvature whose time derivative vanishes in a comoving frame. Two independent numerical codes are developed, and solution sequences t...

The influence of Coulomb collisions between energetic particles in a neutral beam injection (NBI)-heated plasma is numerically investigated utilizing the improved collision operator for orbit-following type Monte Carlo codes. This nonlinear enables collisional effect by non-Maxwellian plasmas including to be taken into account. We have implemented it GNET, one codes solving drift kinetic equati...

The interlace polynomial q was introduced by Arratia, Bollobás, and Sorkin. It encodes many properties of the orbit of a graph under edge local complementation (ELC). The interlace polynomial Q, introduced by Aigner and van der Holst, similarly contains information about the orbit of a graph under local complementation (LC). We have previously classified LC and ELC orbits, and now give an enume...

Abstract An integrated energetic particle transport model has been constructed in JET plasmas constrained by experimental fast ion loss measurements. The incorporates a synthetic detector identical to JET’s thin-foil Faraday cup array. combines analyses from the TRANSP and ORBIT-kick codes with enhanced features for producing diagnostic. Extensions ORBIT code framework allow full-orbit represen...

purpose: to report an extremely rare presentation of isolated orbital xanthogranuloma with no systemic disease, nor dermatologic manifestation. case report: the patient was a 45-year-old man complaining of a mass lesion in the superior and inferior eyelids of his right eye; the lesions had been enlarging slowly and painlessly since 5 years before. other examinations (including skin, heart, etc....

A subspace of a finite extension field is called a Sidon space if the product of any two of its elements is unique up to a scalarmultiplier from the base field. Sidon spaces were recently introduced by Bachoc et al. as a means to characterize multiplicativeproperties of subspaces, and yet no explicit constructions were given. In this paper, several constructions of Sidon spaces arep...

We enumerate the inequivalent self-dual additive codes over GF(4) of blocklength n, thereby extending the sequence A090899 in The On-Line Encyclopedia of Integer Sequences from n = 9 to n = 12. These codes have a well-known interpretation as quantum codes. They can also be represented by graphs, where a simple graph operation generates the orbits of equivalent codes. We highlight the regularity...

A global simulation code is developed to study the ICRF heating combining two global simulation codes: a full wave field solver, TASK/WM, and a drift kinetic equation solver, GNET. The both codes can treat a 3-D magnetic configuration based on the MHD equilibrium by VMEC code. The developed code is applied to the ICRF minority heating in a simple circular tokamak. The ICRF wave propagation is s...

An approach to finding codes for use in direct sequence spread spectrum communications systems is described. It is based upon an analogy between codes having autoand cross-correlation properties desirable for spread spectrum systems, and certain dynamical systems encountered in ergodic theory called systems with Lebesgue spectrum. Such systems are associated with collections of orthogonal funct...
