Ruling out Stellar Companions and Resolving the Innermost Regions of Transitional Disks with the Keck Interferometer
With the Keck Interferometer, we have studied at 2 um the innermost regions of several nearby, young, dust depleted ”transitional” disks. Our observations target five of the six clearest cases of transitional disks in the Taurus/Auriga star-forming region (DM Tau, GM Aur, LkCa 15, UX Tau A, and RY Tau) to explore the possibility that the depletion of optically thick dust from the inner disks is...
متن کاملRuling out and ruling in neural codes.
The subject of neural coding has generated much debate. A key issue is whether the nervous system uses coarse or fine coding. Each has different strengths and weaknesses and, therefore, different implications for how the brain computes. For example, the strength of coarse coding is that it is robust to fluctuations in spike arrival times; downstream neurons do not have to keep track of the deta...
متن کاملRuling Out Bacillus anthracis
Optimization of methods for ruling out Bacillus anthracis leads to increased yields, faster turnaround times, and a lighter workload. We used 72 environmental non-B. anthracis bacilli to validate methods for ruling out B. anthracis. Most effective were the use of horse blood agar, motility testing after isolates had a 2-h incubation in trypticase soy broth, and screening isolates with a B. anth...
متن کاملRuling out chaos in compact binary systems.
We investigate the orbits of compact binary systems during the final inspiral stage before coalescence by integrating the post-Newtonian equations of motion. We include spin-orbit and spin-spin coupling, which, according to a recent study [J. Levin, Phys. Rev. Lett. 84, 3515 (2000)], may cause the orbits to appear chaotic. To examine this claim, we calculate the divergence of nearby trajectorie...
متن کاملRuling out latent homophily in social networks
Despite recent high profile studies identifying counter-intuitive behaviors (e.g. obesity [3]) as being socially contagious, Shalizi and Thomas [12] have demonstrated that homophily on latent attributes is indistinguishable from influence. For sociologists to unequivocally identify influence effects in networks they must rule out the possibility of latent homophily as an explanation. This requi...
