Recent evidence from vector autoregressions points towards the importance of interest rate innovations in explaining output variations. We show that this evidence supports an interpretation of business cycles based on nominal contractual rigidities rather than cotinuous market clearing.
The expression of the density matrix for a spin system subjected to a periodic Hamiltonian is derived in the form of an expansion in powers of the inverse modulation frequency, an extension Ghd Sale Uk
of a method devised by Ruishvili and Menabde and by Mehring. Its application to MAS experiments, as regards the contribution of the dipolar interactions to the sideband intensities, is discussed.
Numerical difficulties in the integration of Euler-Lagrange and similar equations are discussed. A technique for reducing their index from three to two is introduced and it is shown Buy Ghd Wide Straighteners Uk
that variable-order, variable-step BDF methods converge for these index two problems. The practical application of this reduction in a numerical setting is examined.
Trisomy 4 is an uncommon numerical chromosomal aberration in acute leukemia. We describe three cases of trisomy 4, occurring in two patients with acute myeloid leukemia (M1 and M5a) and in one patient with T-cell acute lymphoblastic leukemia. Our results suggest that trisomy 4 may occur in a broader range of hematologic malignancies than previously described.
