Field-dependent maxima in the relaxation rate of the magnetic molecules Mn12-Ac and Fe8-tacn have commonly been ascribed to some resonant tunneling phenomenon. We argue instead that the relaxation can be understood as purely due to phonons. The rate maxima arise because of a Jahn-Tellerlike distortion caused by the coupling of lattice phonons to degenerate Zeeman levels of the molecule at the t...

A full-length cDNA encoding chicken tumor necrosis factor superfamily 15 (TNFSF15) was isolated and its functional role was investigated. TNFSF15 transcripts were primarily expressed in spleen, liver, intestinal intraepithelial lymphocytes (IEL), peripheral blood lymphocytes and bursa. In vitro infection of HTC macrophages with three species of Eimeria sporozoites induced TNFSF15 gene expressio...

This paper presents an ECG data compression technique by the multiscale peak analysis. We define the multiscale peak analysis as the wavelet maxima representation of which the basic wavelet as the second derivative ofa symmetric smoothing function. The wavelet transform of an ECG shows maxima at the start, peak and stop points of five transient waves P through T. The number of wavelet maxima is...

The fine structure of Sarcina maxima and S. ventriculi was studied by electron and phase-contrast microscopy. The two organisms differ mainly with respect to their cell surface. A thick cellulose layer present on the cell wall of S. ventriculi was not observed on the surface of S. maxima. Carbon replication indicated that the outer surface of S. ventriculi is rough in contour, probably as the r...
