Abstract: The chemistry of [13C]methyl phenyl sulfide is exploited to produce new isotopically labeled precursors that allow for the facile assembly of a wide range of labeled molecules from simple and relatively inexpensive starting materials. These compounds are applicable to a variety of research areas such as quantum computing, metabolism and materials science.

Abstract: An RF MEMS switch apparatus includes a planar substrate and an electrostatic actuator formed thereon. The electrostatic actuator includes two sets of interdigitated comb which is capable of moving an armature and a shunt contact head. The armature can be connected to the substrate through a main return spring and one or more contact head support springs. The shunt contact head includes a primary shunt contact and one or more spring-loaded sacrificial contacts. The shunt contact head can serve as a primary contact to bridge a stationary input electrode and an output electrode. The switch is off in a relaxed position and when actuated the primary shunt contact comes into direct mechanical contact with the stationary input electrode and the stationary output electrode. The switch remains closed as long as the actuator is powered and the springs return the armature to the relaxed position when the power is removed.

Abstract: High purity isotopically labeled phosphonic acid esters can be obtained from isotopically enriched Chloro[13C]methyl phenyl sulfide The labeled phosphonic acid esters can then be used as precursors for the one step production of labeled vinyl sulfides, labeled vinyl sulfoxides, and labeled vinyl sulfones. The labeled phosphonic acid esters can also be reacted with a variety of aldehydes to produce extended vinyl systems that are isotopically labeled.

Abstract: A dynamic and synchronized real-time captioning system and method for streaming media. A streaming encoder module can provide a code injection to marry textual data and audio/video (AV) data in order to form a text and/or audio stream. A streaming control module can allow an end-user to specify font format utilized to embed into an AV stream. A delay enhancement tool can be adapted to adjust speed of the text and/or audio stream, which allows the end-user to receive the text and/or audio stream at a proper speed. A customized graphical user interface (CGUI) can be adapted to assist with streaming administration to provide an encoding option, caption source location, delay control and slide control. Therefore, the captioning system can be able to synchronize and deliver the textual data and the AV data for live media streaming at an end-user's system.
