The initial stages of fault development have been recognized in laboratory experiments, but not at seismogenic depths. To fully understand how faults initially develop and begin to evolve, one needs to first recognize and then observe the emerging structure. Recognizing the birth of a fault requires a priori knowledge of the regional tectonics, geologic structure, and seismic history. This info...

Absmct PSK real number codes for the Rayleigh fading channel were proposed in [I]. This paper tabulates the detailed mapping of sc*me simple full-diversity low-delay codes in the original and the manually refined forms. The performance is examined by simulation at various interleaving depths. For the codes considered, the manually refined ones are found to be easy to implement and offer very li...

Given a set P = {p1, . . . , pn} of points and a point q in the plane, we define a function ψ(q) that provides a combinatorial characterization of the multiset of values {|P ∩Hi|}, where for each i ∈ {1, . . . , n}, Hi is the open half-plane determined by q and pi. We introduce two new natural measures of depth, perihedral depth and eutomic depth, and we show how to express these and the well-k...
