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.
