Twisting until it breaks: a rare cause of ICD lead failure.
We describe a rare case of Twiddler's syndrome that resulted in a complex ICD lead fracture involving both the insulation and the conductor. The conductor fracture resulted in noise artefact that was interpreted by the device as ventricular fibrillation, but the patient had not received any shocks because the "episodes" were non-sustained. The patient did not have traditional risk factors for T...
متن کاملSurround with Fewer Speakers
Multichannel audio is now widely available to the consumer. These multichannel formats demand numerous loudspeakers. While five or more loudspeakers in the room may be acceptable to the enthusiast, to the normal consumer this is an undesirable compromise. A more widely acceptable compromise, however, is likely to be a small reduction in the surround performance in exchange for fewer 'boxes' aro...
متن کاملSupermembranes with Fewer Supersymmetries
The usual supermembrane solution ofD = 11 supergravity interpolates between R11 and AdS4× round S7, has symmetry P3×SO(8) and preserves 1/2 of the spacetime supersymmetries for either orientation of the round S7. Here we show that more general supermembrane solutions may be obtained by replacing the round S7 by any seven-dimensional Einstein space M7. These have symmetry P3 × G, where G is the ...
متن کاملTwisting Edwards curves with isogenies
Edwards’ elliptic curve form is popular in modern cryptographic implementations thanks to their fast, strongly unified addition formulas. Twisted Edwards curves with a = −1 are slightly faster, but their addition formulas are not complete over Fp where p ≡ 3 (mod 4). In this short note, we propose that designers specify Edwards curves, but implement scalar multiplications and the like using an ...
متن کاملDoing More with Fewer Bits
We present a variant of the Diffie-Hellman scheme in which the number of bits exchanged is one third of what is used in the classical Diffie-Hellman scheme, while the offered security against attacks known today is the same. We also give applications for this variant and conjecture a extension of this variant further reducing the size of sent information.
