The morphological characteristics of the blood cells may be related to the phylogenetic placement of fish. The so-called large and small lymphocytes may reflect the various function or developmental stages of the same kind of lymphocytes. It needs further investigation whether the basophils are ...

The stages of the cycle in the rat seminiferous epithelium are illustrated for testes fixed by vascular perfusion and embedded in plastic resins. Improved cellular resolution in plastic sections permitted a clearer demarcation of the stages than in paraffin. Quantitative data are presented to support ...
The cascade object detector used cascading to assemble multiple stages of classifiers, using all information collected from the output from a given classifier as additional information for the next classifier in the cascade. The training of the cascade object detector involved feeding the detector with...
Retinal differentiation in the pouch young of the wallaby Macropus eugenii was characterized microscopically and morphometrically. Mitosis occurs until early in the second month in the central retina, and until early in the fourth month, peripherally. Separation of the neuroblast layer by the outer ...

Closure of the otic vesicle conceptualized as a zipper-like model is discussed. We propose that early development of the otic anlage takes place in four stages: (1) shaping (stages HH9–11); (2) triggering of the invagination (stage HH12); (3) early invagination and lateral bending (...
