Eye blink detection for different driver states in conditionally automated driving and manual driving using EOG and a driver camera.

In this article, we examine the performance of different eye blink detection algorithms under various constraints. The goal of the present study was to evaluate the performance of an electrooculogram- and camera-based blink detection process in both manually and conditionally automated driving phases. A further comparison between alert and drowsy drivers was performed in order to evaluate the impact of drowsiness on the performance of blink detection algorithms in both driving modes.

Immunocytochemical observations on the organ distribution of exogenous monomeric and dimerized lysozyme.

Using commercial anti-lysozyme antibodies and anti-dimerized lysozyme rabbit serum produced by us we demonstrated by immunohistochemistry, in some organs of rats, the expression of exogenous egg white lysozyme preparations beside the native lysozyme. After oral administration, the egg white lysozyme was detected in intestinal epithelium, proximal and distal tubules of some nephrons, pulmonary alveolar walls and hepatocytes in the 3rd zone of liver acini, whereas native lysozyme was strongly expressed in intestinal and pulmonary macrophages in both the experimental and control animals. However, expression of the dimerized lysozyme released from the intraperitoneally implanted mini-osmotic pumps and detected using specific antisera was evident only on erythrocytes in intestinal blood vessels.

Cytogenetic findings in a case of Sézary syndrome.

Repeated cytogenetic studies were carried out on a Sézary syndrome patient during a 1-year period. The presence of a single clone of heteroploid (60-86 chromosomes) cells was a permanent finding in the PHA-stimulated blood cultures. The bone marrow was normal.

Replication variants of the human inactive X chromosome. II. Frequency and replication rate relative to the other chromosomes of the complement.

Replication variants of the inactive X chromosome were investigated in lymphocytes from six donors by means of terminal BrdU or thymidine incorporation. There were interindividual differences in the incidence of particular variants. In endoreduplicated and tetraploid cells both allocyclic X chromosomes showed the same replication sequence.

Replication variants of the human inactive X chromosome. I. Variability within lymphocytes of single individuals.

The sequence of DNA replication was studied within the inactive X chromosome in human lymphocytes, by means of the FPG method. Several variants of the replication sequence were found. The number of variants in the cells of a single donor exceeded 2 in each of the 4 normal individuals studied.

Small nuclear RNAs synthesis in PHA-stimulated and nonstimulated human peripheral blood lymphocytes.

Five fractions of small nuclear RNAs (snRNAs) were identified in nuclei of human peripheral blood lymphocytes. They have been designated as: H, G', D, C and A (nomenclature according to Weinberg) in order to decreasing electrophoretic mobility. Their synthesis was observed from the first day of treatment with mitogen and was continued with different intensity during four days of culture.
