The set of completely monotone functions being closed under pointwise convergence, we let t tend to 0 to see that the function 1h(g(u+h)−g(u))is completely monotone. As e−tg is completely monotone, g is of class C∞; letting h tend to 0, we see that Dg is completely ...
Nonetheless it provides a convenient mnemonic for describing the states, and so we shall usually maintain that language in our discussion below. Let us take the closed string to wind around the spatial x-torus. Let the local transverse displacement of the string be h(x). Then under the ...

However, there is still great controversy and few reports on the best surgical method for the treatment of AS combined with thoracolumbar AL. The purpose of this study was to investigate the efficacy of posterior closed osteotomy, debridement and fusion through the fracture line for the treatment ...
Future investigations will be aimed at determining if SPLIT-PIN of series made of N > 2 frames can provide improvement of lateral resolution in confocal microscopy, in addition to the optical sectioning improvement. We share a convenient, user-friendly script running under Matlab. Nevertheless,...
Harmoni and WincsWare to wirelessly interface in real-time to data analysis software such as MATLAB allowed the measurement and characterization of proximal and distal neurochemical activity at multiple time scales (in the order of milliseconds to minutes) acquired under non-restrictive experimental ...
