[1] There is a contradiction between two widely accepted pillars of global tectonics, (1) the central plate tectonic assumption of plate rigidity and (2) the explanation of the relief of the seafloor as being due to lithospheric subsidence from thermal contraction. Here we quantify the rate of predictable horizontal thermal contraction of the lithosphere using depth averages of widely accepted ...

Non-local effects have been traditionally identified as one of the most limiting factors of the performance of Brillouin optical time-domain analyzers. These phenomena, directly linked with the energy gained/lost by the pump pulse, limit the probe power and ultimately the SNR of the system. Several solutions have been proposed, although none offers the possibility to increase the probe power un...

This paper is concerned with a class of low-rate codes constructed from Hadamard code arrays. A recursive encoding principle is employed to introduce an interleaving gain. Very simple trellis codes with only two or four states are sufficient for this purpose, and the decoding cost involved in the trellis part is typically negligible. Both simulation and analytical results are provided to demons...
