This paper presents behavioral modeling of an envelope tracking (ET) power amplifier (PA) excited by an slewrate limited envelope. In order to relax the slew-rate requirements of current efficient envelope amplifiers (EA), we can drive the ET PA with a slower version of the signal’s envelope. However, the resulting amplified signal suffers from nonlinear distortion due to the time-variant gain ...

Objective(s): Production of a recombinant and immunogenic antigen using dengue virus type-3 envelope protein is a key point in dengue vaccine development and diagnostic researches. The goals of this study were providing a recombinant protein from dengue virus type-3 envelope protein and evaluation of its immunogenicity in mice. Materials and Methods: Multiple amino acid sequences of different i...

Two nonparametric methods are presented for forecasting functional time series (FTS). The FTS we observe is a curve at discrete-time point. We address both one-step-ahead and dynamic updating. Dynamic updating forward prediction of the unobserved segment most recent curve. Among two proposed methods, first one straightforward adaptation to k -nearest neighbors univariate forecasting. second bas...
