Amplitude estimation (AE) is a fundamental quantum algorithmic primitive that enables computers to achieve quadratic speedups for large class of statistical problems, including Monte Carlo methods. Recent works have succeeded in somewhat reducing the necessary resources AE by trading off some speedup lower depth circuits, but high quality qubits are still needed demonstrating such algorithms. H...

We present an upgraded processing scheme (eBASCO, extended BASeline COrrection) to remove the baseline of strong-motion records by means a piece-wise linear detrending velocity time history. Differently from standard schemes, eBASCO does not apply any filtering low-frequency content signal. This approach preserves both long-period near-source ground-motion, featured one-side pulse in trace, and...

The procedure for recording the precordial movements was described in the previous publication.' Records were taken from KV1 through KV5, and KV3R. (KV3R is in the same location as KY3, except for being located on the anterior right side of the chest.) KV1, KV2, etc., are used to denote kinetocardiograms taken from areas similar to conventional electrocardiograph chest leads. Records from KY6 a...

[1] An Earth tide signal at the lunar tidal period of 12 hours 25 min has been detected in the Sagnac frequency record of the C-II ring laser 30 m underground at Christchurch, New Zealand. Its amplitude, one part per million of the Earth rotation signal, is much greater than the value of 40 parts per billion expected. Tiltmeter records show that a substantial part of this amplification is geoph...
