Morphological asymmetry is a common feature of animal body plans, from shell coiling in snails to organ placement in humans. The signaling protein Nodal is key for determining this laterality. Many vertebrates, including humans, use cilia for breaking symmetry during embryonic development: rotating cilia produce a leftward flow of extracellular fluids that induces the asymmetric expression of N...

متن کاملThe VOC Insurance Contract of 1613
This paper analyses an insurance contract of the Dutch East India Company (Verenigde Oost-Indische Compagnie, VOC) initiated in 1613. As this contract is an early example of risk management, we try to understand its motivation from recent insights in risk management theory of Froot, Scharfstein and Stein (The Journal of Finance 48, 1993, 1629-1658), in which growth opportunities and costly exte...
متن کاملPG 1613 + 426 : a new sdB pulsator ⋆
We report the detection of short period oscillations in the hot subdwarf B (sdB) star PG 1613+426 from time-series photometry carried out with the 91-cm Cassegrain telescope of the Catania Astrophysical Observatory. This star, which is brighter than the average of the presently known sdB pulsators, with B = 14.14 mag, has T eff = 34 400 K and log g = 5.97, its position is near the hot end of th...
متن کاملVlt Spectroscopy of Blue Supergiants in Ic 1613 1
We present multi-object spectroscopy of young, massive stars in the Local Group galaxy IC 1613. We provide the spectral classification and a detailed spectral catalog for 54 OBA stars in this galaxy. The majority of the photometrically selected sample is composed of Band A-type supergiants. The remaining stars include early O-type dwarfs and the only Wolf-Rayet star known in this galaxy. Among ...
