Although we have not explored all the cases (the transmission and coupling of a P and general S wave across a lam- ination with non-normal incidence), we are confident that for

Abstract.- AuFe and CuFe films, produced by quench condensation, show a round maximum of the initial susceptibility at temperatures T_ whereas annealed films and bulk alloys have

confirmed report of drug resistance in a soil-transmitted nematode infection of humans to the currently used anthelminthic drugs. The existence of

We obtain an analytical solution in the case of cold contacts and cold phonon bath (T ph ¼ 0 ). T ¼ ð P= Þ 1=4 is the maximum temperature reached in the absence of electron

Further- more, the average eigenvalues associated with level A are lower than those for the other levels for the entrance hall environment ( at 50% for level A, versus

This paper studies the capacity of a general multiple-input multiple-output (MIMO) free-space optical intensity channel under a per-input-antenna peak-power constraint and a

Abstract—This paper investigates the capacity of the multiple- input multiple-output free-space optical intensity channel under a per-input-antenna peak-power constraint and a

But the results of [11] and [13] show that small deformations of LeBrun metrics on 4CP 2 with (C ∗ ) 2 -action which have 6-dimensional moduli always drop algebraic dimension of
