Abstract GINGERINO is one of the most sensitive Sagnac laser-gyroscopes based on an heterolithic mechanical structure. It a prototype for GINGER, laser gyroscopes array proposed to reconstruct Earth rotation vector and in this way measure General Relativity effects. Many factors affect final sensitivity gyroscopes, particular, when they are used long-term measurements, slow varying environmenta...

ABSTRACT The objective of this study was to quantify the effect water temperature variations on discharge collapsible thin-walled drip tapes with integrated non-pressure-compensating emitters. tests were conducted in laboratory using an automated test bench. Tests performed determine discharge-pressure curves by varying from 20 50 °C. Nine emitter models three wall thicknesses (6, 8, and 9 MIL)...

Temperature acclimation of soil organic matter (SOM) decomposition is one of the major uncertainties in predicting soil CO 2 efflux associated with the increase in global mean temperature. A reasonable explanation for an apparent acclimation proposed by Davidson and colleagues (2006) based on Michaelis-Menten kinetics suggests that temperature sensitivity decreases when both maximal activity of...

We report on a novel design of an on-chip optical temperature sensor based on a Mach-Zehnder interferometer configuration where the two arms consist of hybrid waveguides providing opposite temperature-dependent phase changes to enhance the temperature sensitivity of the sensor. The sensitivity of the fabricated sensor with silicon/polymer hybrid waveguides is measured to be 172 pm/°C, which is ...

A temperature-insensitive micro Fabry-Pérot (FP) cavity based on simplified hollow-core (SHC) photonic crystal fiber (PCF) is demonstrated. Such a device is fabricated by splicing a section of SHC PCF with single mode fibers at both cleaved ends. An extremely low temperature sensitivity of ~0.273 pm/°C is obtained between room temperature and 900°C. By drilling vertical micro-channels using a f...

Perception of heat or cold in higher organisms is mediated by specialized ion channels whose gating is exquisitely sensitive to temperature. The physicochemical underpinnings of this temperature-sensitive gating have proven difficult to parse. Here, we took a bottom-up protein design approach and rationally engineered ion channels to activate in response to thermal stimuli. By varying amino aci...
