Superconducting behavior even under harsh ambient conditions is expected to occur in La@C60 if it could be isolated from the primary metallofullerene soot when functionalized by CF3 radicals. We use ab initio density functional theory calculations to compare the stability and electronic structure of C60 and the La@C60 endohedral metallofullerene to their counterparts functionalized by CF3. We f...

In an Abelian gauge symmetry, spontaneously broken at a first order phase transition, we investigate the evolution of two bubbles of the broken symmetry phase. The full field equations are evolved and we concentrate in particular on gauge invariant quantities, such as the integral around a closed loop of the phase gradient. An intriguing feature emerges, namely, the geodesic rule, commonly used...

Casimir energy is calculated for the 5D electromagnetism in the warped geometry. It is compared with the flat case(arXiv:0801.3064). A new regularization, called sphere lattice regularization, is taken. It is based on the minimal area principle and is a direct realization of the geometrical approach to the renormalization group. The properly regularized form of Casimir energy, is expressed in a...

The glass polarization effects were introduced in this paper to study the main cause of turn-on drift phenomenon of closed-loop micro-accelerometers. The glass substrate underneath the sensitive silicon structure underwent a polarizing process when the DC bias voltage was applied. The slow polarizing process induced an additional electrostatic field to continually drag the movable mass block fr...

There is mounting observational evidence that the expansion of our universe is undergoing an acceleration. A dark energy component has usually been invoked as the most feasible mechanism for the acceleration. However, it is desirable to explore alternative possibilities motivated by particle physics before adopting such an untested entity. In this work, we focus our attention on an acceleration...

In the present work we deal with the concept of jamming with incomplete information about the jammer. We consider two scenarios. In the first one a jammer could be either present in the environment bringing extra background noise or absent. The user has only statistical knowledge about either presence or absence of the jammer. Namely, the user knows that in the environment only a natural backgr...

We propose a derivation of the empirical Weinberg relation for the mass of an elementary particle and in an inflationary type of universe. Our derivation produces the standard well known Weinberg relation for the mass of an elementary particle, along with an extra term which depends on the inflationary potential, as well as Hubble’s constant. The derivation is based on Zeldovich’s result for th...

Ever since Modigliani and Miller made their irrelevance proposition, a key theme in corporate finance has been to explain the conditions under which capital structure does affect firm value. Split-capital closed-end funds successfully exploit such conditions, being worth on average 11% more than conventional closed-end funds. Cross-section and time-series analyses reveal that the extra value co...

With an increasing usage of in-vehicle systems, drivers have to frequently perceive and respond to the messages from these in-vehicle systems. And previous studies have found that interval between the messages (arrival rate) presented to a driver becomes one of factors affecting driver workload. To reduce driver workload, researchers in adaptive workload management system (Wu et al., 2008) have...

Orthogonal eigenstructure control is a novel active control method for vibration suppression in multi-input multi-output linear systems. This method is based on finding an output feedback control gain matrix in such a way that the closed-loop eigenvectors are almost orthogonal to the open-loop ones. Singular value decomposition is used to find the matrix, which spans the null space of the close...
