BACKGROUND Patients treated with the Melody device (Medtronic) for percutaneous pulmonary valve implantation experience stent fractures in ≈25% of the cases. The aim of this study is to identify the risk factors associated with fracture using 3-dimensional (3D) analyses. METHODS AND RESULTS In situ 3D shape of the Melody stent was reconstructed from 42 patients using procedural biplane fluoro...

Deflation is generally considered as an evil that must be prevented. Economists well are focusing on the question of deflation prevention. This paper examines reasons for why bad and refutes in this context five common errors concerning deflation: That leads to unfair redistribution, induces decrease production, induced price instability chaos, it cause mass unemployment can put economy a disas...

In order to clarify the role of Type I immunologic reactions in the etiology of otitis media with effusion (OME), kindergarten and elementary school children were given routine nasal allergy (NA) tests and otologic tests. Several children among them were evaluated for eustachian tube (ET) function before and after the intranasal histamine challenge, using the inflation-deflation test, and the n...

Suppose that one knows an accurate approximation to an eigenvalue of a real symmetric tridiagonal matrix. A variant of deflation by the Givens rotations is proposed in order to split off the approximated eigenvalue. Such a deflation can be used instead of inverse iteration to compute the corresponding eigenvector. © 2002 Elsevier Science Inc. All rights reserved.

High frequency oscillatory ventilation takes advantage of unique principles of gas flow when respiratory frequencies exceed 3 Hz (180 breaths per minute). These gas flow principles enable the alveolar gas turnover at volumes below or equal to physiologic deadspace. One of these principles is call asymmetrical velocity profile. As Froese and Bryan described in their “State of the Art” article on...

The onset of financial instability in August 2007, which quickly spread across the world, raises a number of questions for policy makers. First, what are the roots of the crisis? Many factors have been emphasized in the debate, including the opacity of complex financial products; the excessive confidence in ratings; weak risk management by financial institutions; massive reliance on wholesale f...

This paper rearranges a key property of anytime algorithms to derive a technique that determines an admissible lower bound on the minimum solution cost. In conjunction with a class of performance metric known as ‘time-focussed metrics’, the technique can be used to determine when to abort the deflation process within an anytime planning algorithm. The aim of this paper is to exploit this techni...

One often hears that one reason deflation should be avoided is because it leads to the expectation of lower prices in the future on the part of consumers. This in turn causes consumers to defer their spending. The consequence of this is reduced demand for products and lower investment by firms now. The net result is weaker economic activity. This paper provides a new approach to verify this view.

As a result of recent changes in the policy governing internet content distribution, such as the institution of per listener royalties for internet radio broadcasters, Content Distributors (CDs) now have an incentive to underreport the size of their audience. Existing metering protocols protect only against the inflation of audience size. We introduce the first protocols for audience metering t...

The calibrated-leak balloon catheter, used for the selective catheterization of intracranial arteries, originally incorporated a silicone microballoon at its tip [1]. Latex balloons have now proven superior in elasticity and tensile strength when compared with balloons made of silicone [2] . Consequently, most workers construct the calibrated-leak balloon catheter by gluing a leaking latex micr...
