MY letter in NATURE of October 21 1, communicating Mr. Booth's correction on this subject, has elicited the information that the exponential integral solution for the absorption of the rays was given ...

We show in this article that fractionally integrated processes with Bloomfield (1973) exponential spectral disturbances can be well approximations to fractional models with AR disturbances. In fact, ...

The exponential and Cayley maps on SE(3) are the prevailing coordinate maps used in Lie group integration schemes for rigid body and flexible body systems. Such geometric integrators are the ...
