Establishment of the Vertebrate Germ Layers,and tissues from those that produce the nervous system and outer tissues. Their discovery in the early nineteenth century transformed embryology from a purely descriptive field into a rigorous scientific discipline, in which hypotheses could be tested by observation and experimentation.

Mechanisms of Vertebrate Germ Cell Determination,differentiating into gametes. How the germ line is specified that allows it to retain these characteristics within the context of a developing embryo remains unknown and is one focus of current research. Germ cell specification proceeds through one of two basic mechanisms: cell autonomous or inducti

Cell Cycle Remodeling and Zygotic Gene Activation at the Midblastula Transition,ys in mammals. Externally developing embryos also undergo synchronous and extraordinarily rapid cell divisions that are accelerated by promiscuous licensing of DNA replication origins, absence of gap phases and cell cycle checkpoints, and preloading of the egg with maternal RNAs and proteins needed

hm still produces a constraints-compatible solution. This property is exploited in superiorization by using such perturbations to steer the algorithm to a solution that is not only constraints-compatible, but is also desirable according to a specified optimization criterion. The approach is very gen

The pattern of absentee voxels in such a surface corresponds to that of absentee pixels in a cover of digital disc with con

The matrix A (over the real field) is said to have the property P. if and only if every set of t columns of A is linearly independent. In this paper, for all positive integers q, we obtain necessary conditions on A* such that . (N × 2.) submatrix A** in A h
