Embryonic divisions

The British prime minister, Gordon Brown, may have been hoping for a quiet Easter break but he soon got warning in the press of an issue that would scupper any such thoughts. The government is backing a bill that will put into law many of the practices currently licensed case by case by the Human Fertilization and Embryology Authority. Britain is currently one of the nations at the forefront of...

Number of Nuclear Divisions

The cell number of the early Drosophila embryo is determined by exactly 13 rounds of synchronous nuclear divisions, allowing cellularization and formation of the embryonic epithelium [1]. The pause in G2 in cycle 14 is controlled by multiple pathways, such as activation of DNA repair checkpoint, progression through S phase, and inhibitory phosphorylation of Cdk1, involving the genes grapes, mei...

Fuzzy Classification of Physiographic Features Extracted from Multiscale DEMs

Geomorphological landforms are generally viewed as Boolean objects. However, recent studies have shown that landforms are more suitable to be viewed as fuzzy objects, whereby a landform is defined as a region in the continuum of variation of the surface of the earth. In this paper, the fuzzy classification of physiographic features extracted from multiscale DEMs is performed. First, the lifting...
