Abstract In the collisionless plasmas of radiatively inefficient accretion flows, heating and acceleration ions electrons are not well understood. Recent studies in gyrokinetic limit revealed importance incorporating both compressive Alfvénic cascades when calculating partition dissipated energy between plasma species. this paper, we use a covariant analytic model flow to explore impact heating...

In this paper a new class of Instrumental Variables estimators for linear processes and in particular ARMA models is developed. Previously, IV estimators based on lagged observations as instruments have been used to account for unmodelled MA(q) errors in the estimation of the AR parameters. Here it is shown that these IV methods can be used to improve efficiency of linear time series estimators...

A density functional theory approach is employed to investigate poly-3-hexylthiophene (P3HT) interfaced with both a semiconducting and metallic carbon nanotube (CNT). For the semiconducting CNT, a type-II heterojunction can form, making such an interface desirable as a photovoltaic heterojunction. In contrast, with the metallic CNT, substantial charge redistribution occurs and the interaction i...

Route flap is an undesirable phenomenon in the Internet and needs to be eliminated for more stable and robust networks. In this paper we present our observations of such persistent route flaps on OSPF in some detail. We show how flaps adversely affect OSPF routing and communication environment in general through our experiments. The current OSPF’s implicit timer damping function is found ineffi...
