The bottom line is this: when patients are advised to have a coronary angiogram, chances are eight out of ten that they do not need it. The critical factor in whether a pa‐ tient needs coronary artery by‐ pass surgery or angioplasty is how well the left ventricular pump is working, not the de‐ gree of blockage or the number of arteries affected. The left ventricle (chamber) of the heart is resp...

This paper describes the Differential Pass Transistor Pulsed Latch (DPTPL) which enhances D-Q delay and reduces power consumption using NMOS pass transistors and feedback PMOS transistors. The proposed flip-flop uses the characteristic of stronger drivability of NMOS transistor than that of transmission gate if the sum of total transistor width is the same. Positive feedback PMOS transistors en...

What drives countercyclical volatility? A large literature has documented that many economic variables are more disperse in recessions, but this could either occur because shocks get bigger or because …rms respond more to shocks which are the same size. Existing evidence that the dispersion of endogenous variables rises in recessions cannot tell us which of volatility or responsiveness is getti...

The Cajon Pass Scientific Drilling Project is a broad, interdisciplinary experiment involving over two dozen principal scientists. Phase I of drilling, coring and downhole experimentation began Dec. 8, 1986 and ended Apri12, 1987 with the hole at a depth of 2115 m, 82 m of core recovered and a wide range of downhole experiments successfully completed. In this paper we briefly outline the scient...

Microscopy of biological specimens often requires low light levels to avoid damage. This yields images impaired by shot noise. An improved measurement accuracy at the Heisenberg limit can be achieved exploiting quantum correlations. If sample damage is the limiting resource, an equivalent limit can be reached by passing photons through a specimen multiple times sequentially. Here we use self-im...

The `ideal' band pass ̄lter can be used to isolate the component of a time series that lies within a particular band of frequencies. However, applying this ̄lter requires a dataset of in ̄nite length. In practice, some sort of approximation is needed. Using projections, we derive approximations that are optimal when the time series representations underlying the raw data have a unit root, or are...

A simple but efficient stereo reverberation control is developed to simulate reverberation. Inspired from previous classic studies, the reverberator is built using simple digital filters, including comb filters and all-pass filters commonly used for digitally simulating reverberation. The digital reverberator incorporates low-pass filters to simulate the air and walls absorption effect, gains t...
