Automatic summarization of voicemail messages using lexical and prosodic features

This article presents trainable methods for extracting principal content words from voicemail messages. The short text summaries generated are suitable for mobile messaging applications. The system uses a set of classifiers to identify the summary words with each word described by a vector of lexical and prosodic features. We use an ROC-based algorithm, Parcel, to select input features (and classifiers). We have performed a series of objective and subjective evaluations using unseen data from two different speech recognition systems as well as human transcriptions of voicemail speech

Simple device for continuous measurement of fluorescent anions and cations in the rat kidney in situ

A simple device for fluorescence measurements on kidney surface in situ (FKS) is described. The device consists of (1) an illuminating unit, (2) a detector, (3) an evaluation unit. The device was developed for measurement of tissue content of anionic sulfofluorescein and cationic 4(4-dimethylaminostyryl)-N-methylpyridinium (ASP) during its secretion by proximal renal tubular cells

Versatile supplement device with remote control for the control of patch clamp experiments

A versatile device for a patch-clamp amplifier is described. This device contains: (i) an acoustic indicator to monitor the input resistance of the patch pipette, which is used in search-mode to indicate the formation of seals; (ii) two pulse generators; and (iii) a staircase generator to produce various pulse and voltage step programs; (iv) a lowpass filter which is used to filter the output of the patch clamp amplifier; and (v) a remote control which is used to control the entire patch clamp experiment. This remote control is used to switch between search-, current clamp-, and voltage clamp-mode, to activate the respective stimulus potential programs, and to control the tape recorder. This electronic device can be easily connected to patch clamp amplifiers
