To determine whether avian bornaviruses (ABVs) were a factor in proventricular dilatation disease (PDD), we used immunohistochemistry, reverse transcription-PCR, and nucleotide sequence analysis to examine paraffin wax-embedded or frozen tissue samples of 31 psittacine birds with this disease. PDD is a fatal disease of psittacine birds associated with(More)
INTRODUCTION Activation of inflammation and coagulation are closely related and mutually interdependent in sepsis. The acute-phase protein, plasminogen activator inhibitor-1 (PAI-1) is a key element in the inhibition of fibrinolysis. Elevated levels of PAI-1 have been related to worse outcome in pneumonia. We aimed to evaluate the effect of functionally(More)
– The paper addresses the problem of estimating the parameters of chirp signals embedded in Gaussian noise. We consider an estimation method based on an approximate linear state space representation of the polynomial phase signal. This approach offers the opportunity to use a nonlinear but exact measurement equation and guides the estimation of the states(More)
Near-complete genome sequences of seven picornavirus (PV) strains isolated from different terrestrial tortoise species were determined and characterized. The genome organization of the strains proved to be similar and displayed a typical PV layout, and the polyprotein-encoding regions showed low similarity to those of other PVs. The predicted regions of the(More)
This paper presents a study concerning the allocation possibilities of the bits generated by the double binary turbo encoder (DBTE) in the modulator symbol, in the case of the quadrature amplitude squared modulation with 256 signal points (256-QAM), in AWGN channel. We compared the bit/frame error rate (B/FER) versus signal to noise ratio (SNR) performances(More)
This paper presents a study on turbo coded bit allocation in the modulator symbol for square quadrature amplitude modulation with 64 signal points. The simulations have involved both single binary turbo code of the LTE standard with coding rates 1/3 and 2/3 and double binary turbo code of the DVB-RCS2 with coding rate 2/3. The simulation results show that(More)

A new Kalman carrier synchronization algorithm is developed for high-order QAM modulated signals which shows fast acquisition times and good frequency tracking performances. The proposed solution relies on a decision directed extended Kalman filter combined with a lock detector which determines the status of the synchronization process, modifying(More)
— The paper implements the well-known leapfrog method of LC-ladder filters simulation by circuits employing only multiple outputs second-generation current controlled conveyors (MO-CCCII) and grounded capacitors. The proposed method is general, because on a hand it implements any type of frequency response and on the other side both all pole and(More)
