Provided in the present invention are a communication method, a network side device, and a vehicle terminal device. In a communication method, a network side device receives a resource scheduling request sent by at least one vehicle terminal device, the resource scheduling request being used for requesting the network side device to allocate a wireless resource for a VDC to the vehicle terminal device, corresponding to the resource scheduling request; the network side device receives vehicle state information sent by the at least one vehicle terminal device, the vehicle state information comprising location information of the vehicle corresponding to the vehicle state information; the network side device allocates, according to the vehicle state information, the wireless resource for the VDC to the at least one vehicle terminal device; and the network side device sends a control message to the at least one vehicle terminal device, the control message carrying information on the wireless resource of the corresponding vehicle terminal device for the VDC. The communication method of the present invention can improve the utilization of wireless resources for the VDC and the reliability of network performance.
The new chiral NHC-iridium complex 3 has been prepared in CH3CN from the reaction between [Ir(COD)Cl](2), NaOAc, KI, and dibenzimidazolium salt 2 which is derived from (S)-2,2'-diamino-6,6'-dimethyl-1,1'-biphenyl. Complex 3 has been characterized by various spectroscopic techniques, elemental analyses, and X-ray diffraction analysis. It has a distorted-octahedral IrC2N2IH core structure, and shows good catalytic activity for the asymmetric hydrosilylation of arylmethyl ketones, leading to 1-arylethanol with moderate ee values.

Apparatus for testing a subject's visual field includes a data processor,
which can be provided by a general purpose computer, coupled to a pupil tracking
system. The data processor is programmed to cause targets to be displayed at different
locations on a display screen and to determine from the pupil tracking system
whether the subject's pupil has moved in response to display of each target.
In some embodiments, the pupil tracking system comprises an infrared camera.
A process for preparing a polymer composite includes reacting (a) a multi-functional
monomer and (b) a block copolymer comprising (i) a first block and (ii) a second
block that includes a functional group capable of reacting with the multi-functional
monomer, to form a crosslinked, nano-structured, bicontinuous composite.
The composite includes a continuous matrix phase with nanometer-sized domains
that include the second block of the block copolymer and a second continuous phase
that include the first block of the block copolymer.
The present disclosure provides drug-ligand conjugates that are potent cytotoxins
and include a linker between the drug and ligand where the linker has a single amino
acid. The disclosure is also directed to compositions containing the drug-ligand
conjugates, and to methods of treatment using them.
A hydraulic cavitation-resistant material consists of a component A and a component B. The component A at least comprises polyaspartic ester, the component B comprises a curing agent, and the material comprises 100 weight parts of polyaspartic ester and 30 to 180 weight parts of the curing agent. The protective material according to the invention has excellent mechanical property and ultra strong weather resistance and ageing resistance. Also disclosed is a preparation method for the hydraulic cavitation-resistant material.
Provided is a method and device for transmitting and receiving data. The data transmission method comprises a first terminal device receiving a first rotation indicator sent by a base station; the first terminal device, based on the first rotation indicator, performing angle rotation processing on a first data symbol using a first angle, and generating a first angle rotation data symbol; the first terminal device performing modulation processing on the first angle rotation data symbol, and generating a first modulation data symbol; the first terminal device transmitting the first modulation data symbol to the base station on a physical resource, enabling the base station to perform demodulation on the first modulation data symbol sent by the first terminal device on the physical resource and a second demodulation data symbol sent by a second terminal device on the physical resource. To a certain extent, the present method reduces interference between data transmitted at a same frequency and in a same time slot, thereby improving the data receiving performance of the receiving terminal.
A web browser has a user interface that includes a content rendering area within the web browser user interface and a control layout area adjacent the content rendering area. The control layout area includes a user-selectable icon that is always available to the user in the control layout area and which is user-configurable. For example, the user-configurable icon may be configured with one of two pre-defined functions. In one illustrative implementation the two pre-defined functions may be a tabs function and a favorites function.
A large-area and smooth stitching method for Huangmei cross-stitch double-sided embroidery. It is necessary to perform embroidering having a total of four passes back and forth on each row of horizontally arranged small squares. The method specifically comprises the following steps: the first pass, "/" lines are embroidered on the back side of even-numbered small squares and "\" lines are embroidered on the front side of odd-numbered small squares; the second pass, "/" lines are embroidered on the back side of the odd-numbered small squares and "\" lines are embroidered on the front side of the even-numbered small squares; the third pass, "\" lines are embroidered on the back side of the even-numbered small squares and "/" lines are embroidered on the front side of the odd-numbered small squares; the fourth pass, "/" lines are embroidered on the front side of the even-numbered small squares and "\" lines are embroidered on the back side of the odd-numbered small squares. The stitching method simultaneously completes continuous embroidering of the lines of "X"s on both the front and back sides of a row of small squares. The method has few needle-movement steps and a consistent needle-movement direction, the method is smooth, and an embroidered product is level and aesthetically pleasing. The method is suitable for double-sided embroidering of a piece of embroidery having a large area and concentrated blocks of colour.
The pyramid die extrusion for a hollow aluminum profile was analyzed to investigate the potential of such innovative dies. For this purpose, the pyramid and conventional porthole dies were respectively designed for a given hollow aluminum profile. And the extrusion process was comprehensively studied by performing different types of finite element simulation, such as the analysis of steady state, transient state and billet skin tracking. The effects of pyramid angle on the evaluation parameters of extrusion, such as extrusion load, material flow, exit temperature, length of transverse weld, quality of longitudinal weld, back end defect and die stress were overall analyzed and compared with the conventional porthole die. Through this study, the advantages and shortcomings of pyramid die were well concluded, which should be important information for die designers and makers.
