Abstract: Use of a transforming growth factor beta (TGF-?) signalling inhibitor for producing a population of brown adipocytes in vitro.

Abstract: A system for facilitating online searches suggests query autocompletion strings (terms and/or phrases) to users during the query entry process, wherein the suggested strings are based on specific attributes of the particular database access system being searched. A string extraction component associated with a database access system, such as a web site of an online merchant, periodically generates a dataset that contains the autocompletion strings for the system. The datasets are preferably biased to favor the database items that are currently the most popular (e.g., best selling or most frequently viewed), and may be customized to particular users or user groups. The datasets are transmitted to users' computing devices, which may include handheld and other wireless devices that lack a full keyboard.

Abstract: A frequency hopping spread spectrum wireless data communications network is disclosed. Time mark frames are transmitted by each base station at a regular cadence and each time mark frame contains all information necessary to determine the hopping sequence of channels, a sub-set of possible channels in use, and the particular channel upon which the time mark was transmitted. Receipt of the time mark resynchronizes a slot clock that is used by the wireless terminals in implementing a media access protocol with defined synchronous time slots. The base station to roaming terminal radio link is half duplex. Each base station broadcasts an end-of-message frame during a hop period that indicates that it has no more data to send during that hop. If there are no inbound messages a roaming terminal needs to send, it puts its receiver in a low power mode until the next hop time approaches.
