Abstract: Systems and methods that facilitate image motion analysis are described herein. According to a first image motion analysis technique a first image is warped according to a locally affine model. The first warped image and a second image are compared and a match between the first warped image and the second image is discovered. A value for a motion parameter is estimated based on the match.

A column of the input matrix corresponds to a vectorized image related to the image sequence. The input matrix is approximated with a low rank matrix having a lower rank than the input matrix. One or more outliers of the input matrix are detected.

Abstract: A liquid crystal cell structure comprising transparent terahertz (THz) windows, alignment layers, protective layers, in-plane electrodes, out-of-plane electrodes, and a liquid crystal (LC) layer.

Abstract: Pyridine-containing polyenes and their applications as metal ion sensors. These polyenes are practically nonluminescent in the solution state but become highly emissive as nanoparticle suspensions in aqueous solutions or thin films in the solid state, due to aggregation-induced emission (AIE). The nanoaggregates of these compounds can work as “turn-off” fluorescent chemosensors for metal ions and display different fluorescence responses to various metal ions. For example, a characteristic red shift in the emission spectra is observed with a terpyridine-containing luminogen in the presence of Zn2+. However, the terpyridine-containing luminogen displays a magenta color upon selectively binding with Fe2+. This allows easy identification of both Zn2+ and Fe2+ ions in aqueous media. The function of the polyenes can be easily tuned by altering the substituent groups. Due to their AIE properties, these polyenes can be used in aqueous solutions and in solid substrates for metal sensing.

Abstract: Systems, methods, and apparatus are described that employ specially designed interference patterns to build an in-band side channel without degrading the effective throughput of the main channel. A first device (100) includes a control component (130) that generates control information and an interference component (140) that transmits the control information (450) through emission of patterned interference data concurrently while other users are transmitting other data (420). A second device (300) receives the patterned interference data and the other data via a single antenna (350) and decodes the patterned interference data to extract the control data (450). The first device (100) transmits the other data (420) on a side channel (440) that resides in the same spectrum as the main channel (410) in which the other data (420) is emitted. The first device (100) encodes the interference patterns such that the control data (450) can be safely transmitted and extracted without effecting other data transmission.
