in order to compare pcr technique with smear method to find out theileria annulata in the cows carrier,cattle over one year was referred to the slaughter, samples were taken randomly since february 88 till may 89. we took blood from ear vein, then fixed with methanol & colored with gimsa at least we sarched for parasits under objective lenses (100x). also for pcr,we took 9ml blood from jagular ...

We consider how the detection of second-order contrast structure depends on the orientation and spatial frequency of first-order luminance structure. For patterns composed of a bandpass noise carrier multiplied by a contrast envelope function, we show that sensitivity to the envelope varies in proportion to the spatial frequency of the carrier. For oriented carriers at low spatial-frequencies, ...

The performance of the Global Navigation Satellite System (GNSS) compass is related to the quality of carrier phase measurement. How to process the carrier phase error properly is important to improve the GNSS compass accuracy. In this work, we propose a dual frequency carrier phase error difference checking algorithm for the GNSS compass. The algorithm aims at eliminating large carrier phase e...

spinal muscular atrophy (sma) is a common autosomal recessive neuromuscular disorder caused by the loss of α-motor neurons in the spinal cord. the survival motor neuron (smn) protein is encoded by 2 genes, smn1 and smn2. the most frequent mutation is the biallelic deletion of exon 7 of the smn1 gene. smn2 cannot compensate for the loss of smn1, due to the exclusion of exon 7. carrier frequency ...

Amplitude modulation (AM) detection was measured with a short (50 ms), high-frequency carrier as a function of carrier level (Experiment I) and modulation frequency (Experiment II) for conditions with or without a notched-noise precursor. A longer carrier (500 ms) was also included in Experiment I. When the carrier was preceded by silence (no precursor condition) AM detection thresholds worsene...

-In this paper, we propose iterative soft-input soft-output (SISO) multi-carrier detection (inter-carrier interference cancellation) and LDPC decoding of the OFDM system in the mobile channel. The proposed SISO multi-carrier detection and sum-product decoding of the LDPC-coded OFDM system can achieve better error rate performance than previous SISO multi-carrier detection and BCJR decoding of c...
