We examine the characteristics of a train of ULF waves observed in the magnetosphere and at ground after the sudden impulse (SI) onset of 8 June 2000. A highly monochromatic and large-amplitude wave at f = 3.3 mHz was observed between 9:10 and 9:50 UT [...]

How this charged dust interacts with the surrounding plasma [...] Publication year: 2012Source: Icarus, Available online 7 February 2012Yuri Shimaki, Masahiko ArakawaKnowing the collisional process among small porous icy bodies in the outer solar system is a key to understanding the formation of EKBOs and the [...] In second-order scalar-tensor theories we study how the Vainshtein mechanism works in a spherically symmetric background with a matter source. In the presence of the field coupling F(f)=e-2Qf with the Ricci scalar R we generally derive the Vainshtein [...] We present a new fully first order strongly hyperbolic representation of the BSSN formulation of Einstein’s equations with optional constraint damping terms. We describe the characteristic fields of the system, discuss its hyperbolicity properties, [...] The eta-photon transition form factor is evaluated in a formalism based on a phenomenological description at low values of the photon virtuality, and a QCD-based description at high photon virtualities, matching at a scale Q02. The high photon [...] We propose two 3-3-1 models (with either neutral fermions or right-handed neutrinos) based on S3 flavor symmetry responsible for fermion masses and mixings. The models can be distinguished upon the new charge embedding (L) relevant to lepton number. [...] Galileon models arise in certain braneworld scenarios as modifications to General Relativity, and are also interesting as field theories in their own right. We show how the galileon model can be naturally generalized to include local gauge symmetries, [...] This paper reports a measurement of D* meson production in jets from proton-proton collisions at a center-of-mass energy of s=7\tev at the CERN Large Hadron Collider. The measurement is based on a data sample recorded with the ATLAS detector with an [...] We present a new investigation of the variability in the metallic calcium ion concentration near the mesopause region, and its relation to the electron concentration during summer and winter seasons at the Arecibo Observatory. During the summer months [...] |
