A Versatile Multichannel Digital Signal Processing Module for
Different techniques have been developed for reading out microcalorimeter sensor arrays: individual outputs for small arrays, and time-division or frequency-division or codedivision multiplexing for large arrays. Typically, raw waveform data are first read out from the arrays using one of these techniques and then stored on computer hard drives for offline optimum filtering, leading not only to...
متن کاملA versatile cis-acting inverter module for synthetic translational switches
Artificial genetic switches have been designed and tuned individually in living cells. A method to directly invert an existing OFF switch to an ON switch should be highly convenient to construct complex circuits from well-characterized modules, but developing such a technique has remained a challenge. Here we present a cis-acting RNA module to invert the function of a synthetic translational OF...
متن کاملA versatile communication module for controlling RNA folding and catalysis.
To exert control over RNA folding and catalysis, both molecular engineering strategies and in vitro selection techniques have been applied toward the development of allosteric ribozymes whose activities are regulated by the binding of specific effector molecules or ligands. We now describe the isolation and characterization of a new and considerably versatile RNA element that functions as a com...
متن کاملA versatile minidisc module for a centrifugal analyzer.
We have developed a centrifugal minidisc module, which extends the versatility of the centrifugal analyzer system with respect to radiation sources, wavelength selectors, radiation detectors, and the analysis performed by the system. The motor, brake, power supply, and control circuitry for the sample/reagent minidisc unit has been repackaged in a compact module, which is easily attached to an ...
متن کاملMonochromator for Aberration-Corrected STEM
In a scanning transmission electron microscope (STEM), the elemental analysis at atomic resolution is realized by the combination with electron energy-loss spectroscopy (EELS), since an aberration corrected probe forming lens system enables us to obtain an electron probe sized about 0.1 nm [1]. In EELS, the energy resolution is mainly limited by the energy spread of the electron source, which i...
