An antimicrobial peptide (AMP) of the cecropin family was isolated by HPLC from plasma of the insect pest, Spodoptera frugiperda. Its molecular mass is 3910.9Da as determined by mass spectrometry. Thanks to the EST database Spodobase, we were able to describe 13 cDNAs encoding six different cecropins which belong to the sub-families CecA, CecB, CecC and CecD. The purified peptide identified as CecB1...
This paper presents a modified COM - based analysis for LSAW ladder and coupled resonator filters. The acoustic sources between the adjacent elements (transducers and gratings) are taken into account by using a gap-type cell instead of a traditional electrode-type cell. Mutual capacitances between the elements are calculated from an electrostatic analysis. The Y-matrix of the device is obtained by...
A new topology for realizing a Single-input/Balanced-output duplexer with excellent rejection along with excellent phase and amplitude imbalance characteristics is presented. In addition to SE/BAL operation, this topology allows superior performances over conventional ladder topology. A Surface Acoustic Wave (SAW) duplexer for Band V CDMA covering the cellular frequency bands has been fabricated using...
