Vernon Remembered
Editor's Note: The world of neuroscience lost one of its pioneers when Vernon B. Mountcastle, M.D., died January 11 in Baltimore at age 96. Often referred to as " the father of neuroscience, " Mountcastle defied early skeptics by showing how cylinders of neurons, dedicated to specific tasks, work together. This month's Cerebrum features remembrances from two colleagues influenced by Mountcastle...
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 کاملColey’s Lessons Remembered
The following four observations point in the same direction, namely that there is an unleveraged potential for stimulating the innate immune system against cancer: (1) experimental treatments with bacterial extracts more than 100 years ago by Coley and contemporaries, (2) a positive correlation between spontaneous regressions and febrile infection, (3) epidemiological data suggesting an inverse...
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.
