A head of time--For the first time, neuroscientists find brain cells that keep track of time with extreme precision（图）
a head of time neuroscientists brain cells time extreme precision
2009/10/21
Keeping track of time is one of the brain's most important tasks. As the brain processes the flood of sights and sounds it encounters, it must also remember when each event occurred. But how does that...
A Penning trap, which can measure the atomic masses with the highest precision, is one of the most important facilities in nuclear physics research nowadays. The precision mass data play an important ...
Studies of the aperture design and its pointing precision in fast neutron penumbral imaging
inertial confined fusion neutron penumbral imaging classical molecular dynamics method
2009/8/14
Neutron penumbral imaging technique is an important diagnosis method in Inertial Confined Fusion, and the design of the aperture shape will affect the resolution of the imaging system. In this paper, ...

Statistical analysis of the precision of the Match method
Statistical analysis Match method polar stratosphere
2009/2/18
The Match method quantifies chemical ozone loss in the polar stratosphere. The basic idea consists in calculating the forward trajectory of an air parcel that has been probed by an ozone measurement (...
A practical demonstration on AMSU retrieval precision for upper tropospheric humidity by a non-linear multi-channel regression method
AMSU retrieval precision upper tropospheric humidity non-linear multi-channel regression method
2009/2/6
A neural network algorithm inverting selected channels from the Advance Microwave Sounding Unit instruments AMSU-A and AMSU-B was applied to retrieve layer averaged relative humidity. The neural netwo...
High-precision isotope measurements of H216O, H217O, H218O, and the Δ 17O-anomaly of water vapor in the southern lowermost stratosphere
High-precision isotope measurements water vapor southern lowermost stratosphere
2009/1/14
We report the first high-precision measurements of δ 18O and Δ 17O at high southern latitudes that can resolve changes in the isotopic composition of water vapor in the lowermost stratosphere and uppe...
This paper discusses the variation and validation of the precision, or estimated random error, associated with the ESA Level 2 products from the Michelson Interferometer for Passive Atmospheric Soundi...

May 10, 2007，A tiny device for calibrating or stabilizing precision lasers has been designed and demonstrated at the National Institute of Standards and Technology (NIST). The prototype device could r...
In the last years, we experienced a complete change of the view of weak interaction physics. Robust results from many experiments as Super-Kamiokande, KamLAND, SNO, K2K, show us that the neutrinos hav...
A brief review of inflation is presented. After having demonstrated the generality of the inflationary mechanism, the emphasis is put on its simplest realization, namely the single field slow-roll inf...
