Several reports have been published on the use of polymorphisms found in the human hemoglobin genes as a means for prenatal diagnosis of sickle cell anemia. The disadvantages of this approach reside in its limited application and the need for family analysis. Here we report that, by use of restriction endonuclease Dde I and diazobenzyloxymethyl-paper transfer procedures, a direct analysis can b...

Base band transmission of digital data requires the use of a low pass channel with a bandwidth large enough to accommodate the essential frequency content of the data stream. However the channel is dispersive in that its frequency response deviates from that of an ideal low pass filter. The result of data transmission over such channel is that each received pulse is affected somewhat by adjacen...

A common problem in automated DNA sequencing when applying the Sanger chain termination method is ambiguous base calling caused by band compressions. Band compressions are caused by anomalies in the migration behavior of certain DNA fragments in the polyacrylamide gel because of intramolecular base pairing between guanine and cytosine residues. To reduce such undesired secondary structures, sev...

<span>Massive internet of things (IoT) in 5G has many advantages as a future technology. It brings some challenges such lot devices need massive connection. In this case, multiple-input multiple-output (MIMO) systems offer high performance and capacity communications. There is challenge correlation between antennas MIMO. This paper proposes three-sectors MIMO base station antenna for 5G-N...

The experimental facts on the stabilisation of martensite in copper base shape memory alloys, of interest to the scientific investigator and the practical alloy processor and user are reported. Factors that have an influence on stabilisation are considered in this respect. The mechanisms proposed in the literature to explain stabilisation are critically examined.

Both for robust fundamental frequency (F0) measurement and to provide a degree of voicing indication, a new algorithm has been developed based on multi-channel autocorrelation analysis. The speech is filtered into eight separate frequency bands, representing the lowest 500 Hz and seven overlapping band-pass channels each about 1000 Hz wide. The outputs of all the band-pass channels are full-wav...
