Abstract: The invention relates to a simple method for preparing an NADH and ethanol biosensing chip, applicable to NADH or ethanol detection in the fermentation field, clinical medicine and food engineering. The sensing material described in the present invention is simple in preparation and can be prepared in batches, the nanogold is uniformly distributed on the surface of nickel hexacyanoferrate, and the quality of the sensing chip prepared based on this material is controllable. The sensing chip uses ethanol dehydrogenase as a biorecognition element and is more selective. The sensor chip detects ethanol and NADH in a wide linear range without dilution at a single detection time of less than 30 s and can realize real-time monitoring of fermentation broth.

Abstract: A computer-implemented method technique includes receiving, at a server, a document including at least one tag. The technique replaces each tag of the document with a placeholder to obtain a modified document. The technique obtains a machine translation of the modified document to obtain a first translated document. The technique provides the first translated document to a human translator at a computing device. The technique receives, at the server, one or more manual translations of the document having been previously generated by one or more other human translators and having had any tags replaced by placeholders. The technique generates a probability score for each of the one or more manual translations based on a level of similarity between portions of text and placeholder association. The techniques then provide the one or more manual translations and the corresponding one or more probability scores to the human translator at the computing device.
