摘要:
Multiple derivatization by chemical reactions of analytes for mass spectrometry is disclosed. The derivatizations enhance the use of MS techniques for analyzing protein samples, particularly when the sequence of a polypeptide is determined by tandem MS/MS. Accurate mass analysis techniques are described for use in sequencing polypeptides, together with the use of sequencing data in protein analysis. An apparatus and method for calibrating a mass spectrometer by internally introducing calibration masses at a post-source stage of the mass spectrometer is also provided. Lock mass ions mix with the derivatized polypeptide analyte ions prior to mass analysis.

摘要:
Double strength loppers employ double leverage effects and have two crossed pivoting blades, a main blade and an auxiliary blade, an upper handle and a lower handle correspondingly matching with the two blades, an upper gear at the end of the upper handle and a lower gear at the end of the lower handle. The lower gear matches with the blade driving gear and the blade driving gear matches with the auxiliary blade. When swinging the upper handle and/or the lower handle, a first leverage effect is created from a first fulcrum that is the contact point between the upper gear and the lower gear, while a second leverage effect is created from a second fulcrum that is the contact point between the lower gear and the blade driving gear. Such double levers and double strength effects significantly reduce the force applied upon the handles, therefore reducing the required labor.

Techniques include constraining depth intra mode coding in a three-dimensional (3D) video coding process, such as 3D-High Efficiency Video Coding (3D-HEVC). In some examples, the techniques for constraining depth intra mode coding may prevent transform tree nodes from being split into sub-transform tree nodes when a depth prediction unit that corresponds to the transform tree node is predicted according to a depth modeling mode (DMM). In further examples, the techniques for constraining depth intra mode coding may prevent the DMM mode from being used when the maximum transform unit size that corresponds to a depth prediction unit is greater than the size of the depth prediction unit. The techniques for constraining depth intra mode coding may prevent characteristics of the DMM prediction modes used in 3D-HEVC and characteristics of the transform tree subdivision used in 3D-HEVC from interfering with each other.
摘要:
This disclosure describes techniques for signaling and processing information indicating simplified depth coding (SDC) for depth intra-prediction and depth inter-prediction modes in a 3D video coding process, such as a process defined by the 3D-HEVC extension to HEVC. In some examples, the disclosure describes techniques for unifying the signaling of SDC for depth intra-prediction and depth inter-prediction modes in 3D video coding. The signaling of SDC can be unified so that a video encoder or video decoder uses the same syntax element for signaling SDC for both the depth intra-prediction mode and the depth inter-prediction mode. Also, in some examples, a video coder may and/or process a residual value generated in the SDC mode using the same syntax structure, or same type of syntax structure, for both the depth intra-prediction mode and depth inter-prediction mode.

The method includes: in an intraframe encoding mode for depth images, generating a non-all-zero residual and an all-zero residual when a prediction unit is encoded; and performing a rate-distortion optimization selection between the non-all-zero residual and the all-zero residual, as a residual encoding scheme of the prediction unit. The device is applied to 3D video encoding or multi-view video encoding. The device includes: a residual generation unit configured to generate, in an intraframe encoding mode for depth images, a non-all-zero residual and an all-zero residual when a prediction unit is encoded; and a rate-distortion optimization selection unit configured to perform a rate-distortion optimization selection between the non-all-zero residual and the all-zero residual, as a residual encoding scheme of the prediction unit.

Double strength pruners have two crossed pivoting blades, a main blade and an auxiliary blade, upper and lower handles correspondingly matching the two blades, a blade driving gear on the auxiliary blade, and upper and lower gears at the end of the upper and lower handles, respectively, the lower gear matching the blade driving gear. When swinging the upper handle and/or the lower handle, a first leverage effect is created from a first fulcrum, which is the contact point between the upper and lower gears, while a second leverage effect is created from a second fulcrum, which is the contact point between the lower gear and the blade driving gear. Such double levers and double strength effects can significantly reduce the force applied upon the handles, reducing the required labor. The upper gear, lower gear, upper handle and lower handle are detachable structures, easy for maintenance and replacement.
摘要:
This disclosure describes techniques for 3D video coding. In particular, this disclosure is related to techniques for advanced residual prediction (ARP) in 3D-HEVC. According to one techniques of this disclosure, when performing inter-view ARP for a bi-directionally predicted block, the video coder may determine a motion vector for a first corresponding block as part of performing ARP for a first prediction direction and reuse that determined motion vector when performing ARP for a second prediction direction. According to another technique, for a bi-directionally predicted block, a video coder may apply ARP in only one direction for a chroma component of a block but apply ARP in two directions for a luma component of the block. According to another technique, a video coder may selectively apply ARP to chroma components based on block size. These simplifications, as well as other techniques included in this disclosure, may reduce overall coding complexity.
