The excitatory responses of deflationary slowly adapting pulmonary stretch receptor (SAR) activity to lung deflation ranging from approximately -15 to -25 cm of H(2)O for approximately 5 s were examined before and after administration of flecainide, a Na(+) channel blocker, and K(+) channel blockers, such as 4-aminopyridine (4-AP) and tetraethylammonium (TEA). The experiments were performed in ...

BACKGROUND This study provides the first large-volume (1000 implant) comparison of the deflation rates of Poly Implant Prosthesis prefilled textured saline breast implants versus a control group of Mentor Siltex textured saline implants. METHODS A consecutive series of 500 Poly Implant Prosthesis prefilled textured saline breast implants was compared with a consecutive series of 500 Mentor Si...

Aggressive early deflation is a QR algorithm deflation strategy that takes advantage of matrix perturbations outside of the subdiagonal entries of the Hessenberg QR iterate. It identifies and deflates converged eigenvalues long before the classic small-subdiagonal strategy would. The new deflation strategy enhances the performance of conventional large-bulge multishift QR algorithms, but it is ...

DEFLATION IS BACK. In the six months from October 1998 to March 1999, some 438 articles about deflation appeared in major U.S. newspapers, compared with only 36 in the first half of 1997 and 10 in the first half of 1990. For sixty years, ever since the middle years of the Great Depression, deflation was a nonissue. Next to no one worried about it. Next to no one viewed a general decline in the ...

Recently, it has been recognized that a single airway sensory unit may contain multiple receptive fields and that each field houses at least one encoder. Since some units respond to both lung inflation and deflation, we hypothesized that these units contain heterogeneous encoders for sensing inflation and deflation, respectively. Single unit activities were recorded from the cervical vagus nerv...

This article introduces the concept of isosingular sets, which are irreducible algebraic subsets of the set of solutions to a system of polynomial equations that share a common singularity structure. The definition of these sets depends on deflation, a procedure that uses differentiation to regularize solutions. A weak form of deflation has proven useful in regularizing algebraic sets, making t...

In this paper we propose a new deflation algorithm for line spectral pair (LSP) computation. This algorithm is much more reliable than other methods based on deflation.

In this paper we consider deflations (inverse pocket flips) of n-gons for small n. We show that every pentagon can be deflated after finitely many deflations, and that any infinite deflation sequence of a pentagon results from deflating an induced quadrilateral on four of the vertices. We describe a family of hexagons that deflate infinitely for a specific deflation sequence, yet induce no infi...
