The problem of choosing the number and the thoracic locations of the leads needed for reconstructing body surface maps of heart potentials is considered. In a previous work (P. Barone, In "Computers in Cardiology" (K. L. Ripley, Ed.), pp. 491-494. IEEE Computer Sot. Press, Washington, DC, 1985) the

## Abstract Olig2 is a basic helixβloopβhelix (bHLH) transcription factor essential for development of motoneurons and oligodendrocytes. It is known that Olig2^+^ cells persist in the central nervous system (CNS) from embryonic to adult stages and that the number of Olig2^+^ progenitors increases i
In this paper we explore the computation of the matrix exponential in a manner that is consistent with Lie group structure. Our point of departure is the decomposition of Lie algebra as the semidirect product of two Lie subspaces and an application of the Baker-Campbell-Hausdorff formula. Our result
