We consider a system of coupled harmonic oscillators on a cubic lattice. The force constants are supposed to take two distinct values at random according to a bond concentration x. The density of states (DOS) is evaluated both by numerical diagonalisation and in coherent-potential approximation (CPA). There is excellent agreement between the results of the two methods. Near the concentration, w...
The day-time eastward equatorial electric field (EEF) in the E-region plays an important role in equatorial ionospheric dynamics. It is responsible for driving the equatorial electrojet (EEJ) current system, equatorial vertical ion drifts, and the equatorial ionization anomaly (EIA). Due to its importance, there is much interest in accurately measuring the EEF. However, there is a severe lack o...
Although η−η mixing is qualitatively well understood as a consequence of the U(1)A anomaly in QCD together with a broken SU(3)F flavor symmetry, until recently the values of decay and mixing parameters of the η and η were only approximately known, e.g. values for the octet-singlet mixing angle between −20 and −10 could be found in the literature. New experimental data, especially for the reacti...
Two event-related brain potential experiments were conducted to investigate the functional interplay between discourse-level referential processing and local syntactic/semantic processing of phrases. We manipulated both the syntactic/semantic coherence of a noun phrase (NP) and the referential ambiguity of the same NP. Incoherence of the NP elicited a P600 effect in both experiments. Referentia...
system, equatorial vertical ion drifts, and the equatorial ionization anomaly (EIA). Due to its importance, there is much interest in accurately measuring the EEF. However, there is a severe lack of high quality data with the notable exception being the JULIA coherent scatter radar in Peru. In this work, we use CHAMP satellite-derived latitudinal current profiles of the day-time EEJ in order to...
We measured the low temperature subgap resistance of titanium nitride (superconductor, Tc=4.6K)/highly doped silicon (degenerated semiconductor) SIN junctions, where I stands for the Schottky barrier. At low energies, the subgap conductance is enhanced due to coherent backscattering of the electrons towards the interface by disorder in the silicon (”reflectionless tunneling”). This Zero Bias An...
We investigate whether the anomalous tensor operators with the Lorentz structure σμν(1 + γ5) ⊗ σμν(1 + γ5), which could provide a simple resolution to the polarization anomaly observed in B → φK∗ decays, could also provide a coherent resolution to the large B(B → ηK∗) and survive bounds from B → ηK decays. Parameter spaces satisfying all these experimental data are obtained, and found to be dom...
We have measured the very low temperature (down to 30mK) subgap resistance of Titanium Nitride (Superconductor, Tc = 4.6K)/highly doped Silicon (Semiconductor) SIN junction (the insulating layer I stands for the Schottky barrier). As the temperature is lowered below the gap, the resistance increases as expected in SIN junction. Around 300mK, the resistance shows a maximum and decreases at lower...
We present an analysis of ice nucleation kinetics from near-ambient pressure water as temperature decreases below the homogeneous limit TH by cooling micrometer-sized droplets (microdroplets) evaporatively at 103-104 K/s and probing the structure ultrafast using femtosecond pulses from the Linac Coherent Light Source (LCLS) free-electron X-ray laser. Below 232 K, we observed a slower nucleation...
Anomaly is deviation from common rules and in finance it can be defined as a pattern in the average of stock return that is not consistent with the prevailing asset pricing models literature. For anomaly investigation two common methods are used: portfolio approach and individual firm approach. This paper wants to shed light on anomalies of capital asset pricing model at the individual firm lev...
