Detection and differentiation of cytomegalovirus antibodies by radioimmunoassay

Journal of Virological Methods, 1980
A sensitive radioimmunological method was adapted for the assay of anticytomegalovirus IgG and IgM antibodies. Binding of immunoglobulins G with cytomegalovirus (CMV) antigens was greatly reduced when an antigen prepared by sonication of the infected cells in glycine buffer was used in place of the antigen obtained by freezing and thawing of the cells.

Differential Property Monitoring for Backdoor Detection

A faithful characterization of backdoors is a prerequisite for an effective automated detection. Unfortunately, as we demonstrate, formalization attempts in terms of temporal safety properties prove far from trivial and may involve several revisions.

Doppler-corrected differential detection of MPSK

IEEE Transactions on Communications, 1989
An open-loop technique is presented for estimating and correcting Doppler frequency shift in an M-ary differential phase-shift-keyed (MDPSK) receiver. The novelty of the scheme is based on the observation that whereas the change in phase of the received signal over a full symbol contains the sum of the data (phase) and the Doppler-induced phase shift ...

Differential DNA Damage Detected in Hybridomas

Hybridoma, 1993
Monoclonal antibody technology has improved over recent years. However, there remains a serious problem with regard to the stability and antibody production of the hybrid cell lines. In order to investigate the potential increased sensitivity of hybridomas to DNA damage, we produced a monoclonal antibody producing cell line in our laboratory.

On the Detection of Differentially Encoded Polyphase Signals

IEEE Transactions on Communications, 1972
Any digital communication system that employs coherent detection requires coherent reference signals for proper operation. This paper is concerned with the transmission and detection of differentially encoded multiple phase-shift-keyed (MPSK) signals and the ambiguity resolution problem that results from suppression of the transmitted carrier.

A local mechanism for differential velocity detection

Vision Research, 1981
Abstract Differential velocity detection in the fovea was used to probe the properties of a local motion mechanism. Human observers can detect differences in velocity of less than 5% even for a 200 msec target duration. This precision is not based on variations in the distance traversed by the target or in the total target duration.
