Advanced Science, EarlyView.ABSTRACT Engineered ascorbate peroxidase APEX2 has been widely used for spatially restricted profiling of subcellular biomolecules, but its catalytic efficiency toward newly developed probes such as biotin‐aniline (Btn‐An) remains suboptimal. To overcome this limitation, we performed yeast surface display‐based directed evolution to enhance APEX2 ...

Noise and thermal stability of vibrating micro-gyrometers preamplifiers [PDF]
, 2007 The preamplifier is a critical component of gyrometer's electronics. Indeed the resolution of the sensor is limited by its signal to noise ratio, and the gyrometer's thermal stability is limited by its gain drift.
