In this paper, the static rolling test of quartz flexible accelerometer in gravitational field is studied. We establish its error model and use the method of total least squares for identification. In addition, we study the influence of environment temperature on the accelerometer. The accelerometer output is corrected by compensation the bias and the scale factor. The results of the comprehens...

Self-sustainable oscillation of KaiC phosphorylation has been reconstituted in vitro, demonstrating that this cycle is the basic time generator of the circadian clock of cyanobacteria. Here we show that the ATPase activity of KaiC satisfies the characteristics of the circadian oscillation, the period length, and the temperature compensation. KaiC possesses extremely weak but stable ATPase activ...

Gas exchange of Eurasian watermilfoil (Myriophyllum spicatum L.) indicated a near-zero CO(2) compensation point and a high temperature optimum for photosynthesis. These properties are characteristic of plants fixing CO(2) by a beta-carboxylation mechanism. Operation of the Calvin cycle was shown and no evidence for beta-carboxylation was obtained. These results indicate that near-zero CO(2) com...

We demonstrate a high sensitivity all-fiber spectroscopic methane sensor based on photothermal interferometry. With 2.4-m-long anti-resonant hollow-core fiber, 1654 nm distributed feedback laser, and Raman fiber amplifier, noise-equivalent concentration of ∼ <...

Recorded signals from a guided wave structural health monitoring system are sensitive to damage but also to even small temperature changes. Previous work has shown that reasonable temperature compensation can be achieved by first selecting an optimal baseline and then stretching it to match the current signal of interest. However, this method is not perfect and its efficacy depends upon many fa...
