Reproductive tourism and the regulatory map.
Consider the case of Sharon Saarinen. In 2002, the 38-year-old hairdresser traveled to Beirut in desperate pursuit of a baby. Four years earlier, she and her husband had had their first high-tech child, a daughter conceived through cytoplasmic transfer. In this process, fertility specialists remove a single egg from the mother-to-be and inject it with cytoplasm from the egg of another (usually ...
متن کاملAstro Teller
Most interesting problems do not have solutions that are simple mappings from the inputs to the correct outputs; some kind of internal state or memory is needed to operate well or optimally in these domains. Traditionally, genetic programming has concentrated on solving problems in the functional/reactive arena. This may be due in part to the absence of a natural way to incorporate memory into ...
متن کاملComment on astro-ph/0507588 and astro-ph/0508483
Guidorzi has now written two papers (astro-ph/0507588 and astro-ph/0508483, both accepted to MNRAS) on the GRB variability-luminosity correlation in which he finds that expanded samples of L vs. V data are not well described by a power law because the scatter of the data around such a model is more than can be accounted for by the data’s statistical errors alone (sample variance) – “in contrast...
متن کاملAstro-ph Communication: Simulations of the Wmap Internal Linear Combination Sky Map
Following this astro-ph communication, we release a set of 10 000 WMAP ILC simulations, produced as described by Eriksen et al. (2004). We strongly encourage that an analysis of these simulations accompanies any scientific analysis of the observed ILC map, in order to assess the stability of the results. For examples of such analyses, we refer the reader to our original paper. In particular, Fi...
متن کاملVisible wavelength astro-comb.
We demonstrate a tunable laser frequency comb operating near 420 nm with mode spacing of 20-50 GHz, usable bandwidth of 15 nm and output power per line of ~20 nW. Using the TRES spectrograph at the Fred Lawrence Whipple Observatory, we characterize this system to an accuracy below 1m/s, suitable for calibrating high-resolution astrophysical spectrographs used, e.g., in exoplanet studies.
