Abstract:
The present invention is directed to a process for the preparation of a compound of formula (X-a) or a pharmaceutically acceptable salt form thereof, wherein: R1 is selected from the group consisting of: C1-5 alkyl substituted with 0-5 R1a, —(CH2)r—C3-10 cycloalkyl substituted with 0-5 R1a, and —(CH2)r-aryl substituted with 0-5 R1a. Compounds of Formula (X-a) are macrocyclic molecules containing anti-succinate residues which inhibit metalloproteinases such as aggrecanase, and the production of tumor necrosis factor (TNF). The anti-succinates are formed by an Ireland Claisen rearrangement of a silyl ketene acetal which proceeds with high stereoselectivity.

Abstract:
A method for toning mapping high dynamic range (HDR) video for display in low dynamic range display comprises accessing the HDR video; producing a luminance information for the individual frames; partitioning different consecutive groups of frames into segments responsive to the luminance information; classifying the segments into static luminance segments and transient luminance segments; producing a tone mapping parameter set for the static luminance segments; producing a tone mapping parameter set for at least one of the transient luminance segments responsive to the tone mapping parameter set of an adjacent static luminance segment; and tone mapping the static luminance segments and transient luminance segments according to the respective tone mapping parameter sets.
Abstract:
A method and system for calibration and compensation of color in a three dimensional display system includes user calibration of individual color channels using a multiplicity of grey screens while viewing with three dimensional glasses. Look-up tables are generated to ease conversion of input pixels to color corrected pixels to pre-distort the color of the pixels being driven by the three dimensional display system. Input pixels are then converted using the look-up tables and color corrected frames are displayed to a user. The pre-distortion effect allows a user to perceive colors in the three dimensional system as intended with the distortions caused by the viewing glasses and other aspects of the three dimensional display system.
Abstract:
A method and a device for tracking background noise in a communication system are provided. The method includes: calculating a SNR of a current frame according to input audio signals; increasing a frame counter, and calculating tone features and signal steadiness features of the current frame if the SNR of the current frame is not less than a first threshold; determining the possibility of a time window including a noise interval according to the calculated tone feature values and signal steadiness feature values of each frame of the time window when the frame counter is increased to the length of the time window; and extracting noise features in the time window. Existence of background noise is analyzed continuously in a time window, so that background noise that changes frequently.
