A new large area lanthanum hexaboride plasma source.
A new 18x18 cm(2) active area lanthanum hexaboride (LaB(6)) plasma source for use in a dc discharge has been developed at UCLA. The cathode consists of four tiled LaB(6) pieces indirectly heated to electron emission (1750 degrees C) by a graphite heater. A molybdenum mesh anode 33 cm in front of the LaB(6) accelerates the electrons, ionizing a fill gas to create a 20x20 cm(2) nearly square plas...
متن کاملBLOCK-HF: CRT gains new ground
The detrimental effects of chronic right ventricular (RV) pacing were first demonstrated 10 years ago when the DAVID trial clearly demonstrated the hazards of unnecessary RV pacing including worsening left ventricular (LV) function, increased heart failure hospitalization and increased mortality. This finding was confirmed in other studies, prompting the development of various device algorithms...
متن کاملImprovement in CRT: new strategies, better choices
Cardiac resynchronisation therapy (CRT) emerged more than a decade ago as a useful form of device therapy for heart failure associated with abnormal ventricular conduction indicated by a wide QRS complex [1, 2]. According to the Guidelines of the European Society of Cardiology (ESC) entitled Cardiac Pacing and Cardiac Resynchronization Therapy (ESC Clinical Practice Guidelines, 2013), CRT has c...
متن کاملA New Attack on RSA and CRT-RSA
In RSA, the public modulus N = pq is the product of two primes of the same bit-size, the public exponent e and the private exponent d satisfy ed ≡ 1 (mod (p−1)(q−1)). In many applications of RSA, d is chosen to be small. This was cryptanalyzed by Wiener in 1990 who showed that RSA is insecure if d < N. As an alternative, Quisquater and Couvreur proposed the CRT-RSA scheme in the decryption phas...
متن کاملCRT-D or CRT-P in CRT-indicated patients?
HRV parameters and 6-minute walking test, functional capacity, right ventricular systolic function, BNP and hs-troponin-I levels. Most common cause of death in these patients is arrhythmia, and autonomic dysfunction may be triggering factor (2). HRV parameters are now being used for prognostic evaluation in PAH patients. There are also studies suggesting HRV reduction may be associated with mor...
