Cavity-locked ring-down spectroscopy

Verification of a Locked CFD Approach to Cool Down Modeling

Increasing demand on the performance of Subsea Production Systems (SPS) suggests a need for more detailed investigation of fluid behavior taking place in subsea equipment. Complete CFD cool down analyses of subsea equipment are very time demanding. The objective of this paper is to investigate a Locked CFD approach, which enables significant reduction of the computational time and at the same t...

Pound-Drever-Hall-locked, frequency-stabilized cavity ring-down spectrometer.

We describe a high sensitivity and high spectral resolution laser absorption spectrometer based upon the frequency-stabilized cavity ring-down spectroscopy (FS-CRDS) technique. We used the Pound-Drever-Hall (PDH) method to lock the probe laser to the high-finesse ring-down cavity. We show that the concomitant narrowing of the probe laser line width leads to dramatically increased ring-down even...

Wherein Is Set down What City Marketing Is

In a place at La Mancha El Quijote decided to go out as a knight-errant in search of adventure. In one of his escapades El Quijote met Master Pedro and his divining past-things ape. Master Pedro was a famous puppet-showman, exhibiting a show of the release of Melisendra and thus, for the very first time in our history, he linked marketing and technology. The Master Pedro’s show was mainly used ...

Noradrenergic neurons of the locus coeruleus are phase locked to cortical up-down states during sleep.

Nonrapid eye movement (NREM) sleep is characterized by periodic changes in cortical excitability that are reflected in the electroencephalography (EEG) as high-amplitude slow oscillations, indicative of cortical Up/Down states. These slow oscillations are thought to be involved in NREM sleep-dependent memory consolidation. Although the locus coeruleus (LC) noradrenergic system is known to play ...
