Amyloid peptide beta (Aβ), as the main component of the amyloid plaques present in the patient brains of Alzheimer's disease (AD), is a group of peptides with typical number of amino acid residuals from 39 to 43. Aβ1−40 is the most dominant type in all Aβ variants and possesses the most closely correlation with late-onset AD. Synthetic Aβ1−40 from monomer to fibril in vitro shares many features with...
Minimum resolvable temperature difference (MRTD) is an important index for the infrared imaging system. In practice, the measurement of MRTD is observing the images obtained through testing platform by human eyes. This method is unstable and time consuming as it's susceptible to psychological and physiological factors of human. In this paper, an MRTD objective measurement method based on adaptive...
The ultracold atoms served as quantum references is a key part of optical lattice clocks, and the thermal dynamics of the atoms in the optical lattice affects the uncertainty and stability of the lattice clocks. Since the carrier spectrum of clock transition in lattices reflects the thermal dynamics of cold atoms, we can obtain the temperature of atoms by measuring the carrier spectrum in 171Yb optical...
Nowadays, according to the production and management on the offshore oil and gas platforms, the wireless sensor networks(WSNs) will have different reply to the platforms. For the offshore Oil and Gas platforms, switching from wired to wireless sensors, allowing data collection in remote or hostile areas. Reliability, power consumption and standard are three most important concerns that related to...
