摘要:
A digital predistortion processing method and device, the method comprises: performing digital predistortion processing on a baseband signal according to a first predistortion correction parameter, converting the baseband signal after digital predistortion processing into a radio-frequency signal, dividing the radio-frequency signal, and respectively outputting each path of radio-frequency signal to a distinct power amplifier; and, coupling and outputting the radio-frequency signal output by each power amplifier to a feedback link for combination to obtain a combined signal, and performing conversion processing on the combined signal; and generating a predistortion correction parameter according to the combined signal after conversion processing and the baseband signal before digital predistortion processing, and updating the first predistortion correction parameter to a second predistortion correction parameter.

The present invention discloses an integrated analysis device for simultaneously detecting exhaled breath condensates (EBCs) and volatile organic compounds (VOCs) in human exhaled breath. The device comprises a module for sampling, separating and enriching a detected object, an EBCs detection module and a combined VOCs detection module. The module for sampling, separating and enriching a detected object is connected with the EBCs detection module via a syringe pump for sample injection. The module for sampling, separating and enriching a detected object is connected with the combined VOCs detection module by a capillary separation column. In the present invention, it is achieved that EBCs and VOCs in human exhaled breath are simultaneously sampled, separated and condensed; the heavy metal ions, cell factors, etc. in the collected EBCs are detected with a light addressable potentiometric sensor (LAPS); the condensed VOCs can be quantitatively detected by the combined VOCs detection module with a high sensitivity; and a heating rod and a platinum resistor can be conveniently replaced because a separated outlet heating piece is designed in the combined VOCs detection module.

摘要:
Ethylene and allyl- or vinylsilanes are efficiently copolymerized by certain late transition metal complexes containing selected bidentate or tridentate ligands. The resulting novel polymers may be crosslinked by moisture when vinylsilane contains groups bound to silicon which are hydrolyzable. The polymers are useful for wire coating, crosslinked foams, pipes, and other uses.
摘要:
Mixtures of different polyolefins may be made by direct, preferably simultaneous, polymerization of one or more polymerizable olefins using two or more transition metal containing active polymerization catalyst systems, at least one of which contains cobalt or iron complexed with selected ligands. The polyolefin products may have polymers that vary in molecular weight, molecular weight distribution, crystallinity, or other factors, and are useful as molding resins and for films.

Disclosed are new dicycloazaalkane derivates represented by general formula (I), preparation processes and pharmaceutical compositions containing them, and the uses for treatment especially for dipeptidyl peptidase inhibitor (DPP-IV), in which each substitute group of general formula (I) is as defined in specification.
摘要:
A computer implemented method, a tangible computer usable medium, and a data processing system allocate materials to an automated purchase assembly conversion process to support a dynamic configure-to-order production operation. A configure-to-order backlog order is analyzed to determine demand for a particular purchase assembly. If the demand for the particular purchase assembly can be filled with an on-hand purchase assembly in inventory, the on-hand purchase assembly in inventory is allocated to fill the demand. If the demand for the particular purchase assembly can not be filled with an on-hand purchase assembly in inventory, a determination is made as to whether the demand for the particular purchase assembly can be filled by reallocating other similar on-hand purchase assembly in inventory and on-hand individual parts. If the demand for the particular purchase assembly can be filled by reallocating other on-hand purchase assembly in inventory and on-hand individual parts, the on-hand purchase assembly in inventory and the on-hand individual parts are reallocated to fill the demand.

摘要:
Disclosed is an animal litter that includes a palm oil residue, possibly in combination with another absorbent material such as whole ground grain, virgin germ, seed meal, spent germ or clay. The palm oil residue may be palm kernel cake, palm oil sludge, or palm pressed fiber. Also disclosed are a method for removing animal waste and a process for preparing an animal litter. The method for removal of animal waste includes allowing an animal to excrete waste into a container that includes a litter, the litter comprising a palm oil residue. The process for preparing an animal litter comprises combining the materials that make up the litter to form the litter.
