Ringing in the New Year

www.landesbioscience.com oxidative Medicine and cellular Longevity 1 The excitement and enthusiasm for the New Year brings with it new thoughts and innovative promises for pioneering avenues of drug discovery and new treatment strategies for a host of disorders. Such thinking is not only optimistic, but also necessary considering the economic costs healthcare brings to any country. For example,...

Ringing Js refinements

Both the four-point and the uniform cubic B-spline refinement (i.e. subdivision) schemes double the number of vertices of a closed-loop polygonal curve P and respectively produce sequences of vertices fk and bk. The Js refinement proposed here produces vertices vk=(1–s)fk+sbk. Iterative applications of Js yield a family of curves parameterized by s. It includes the four-point curve (J0), the un...

Listening for Ringing Black Holes

The gravitational radiation produced by binary black holes during their inspiral, merger, and ringdown phases is a promising candidate for detection by the first or second generation of kilometer-scale interferometric gravitational wave antennas. Waveforms for the last phase, the quasinormal ringing, are well understood. I discuss the feasibility of detection of the quasinormal ringing of a bla...
