    摘要: Method and device in a node used for wireless communications. A first node receives first configuration information; transmits a first positioning reference signal on a first time-frequency resource block, transmits a second positioning reference signal on a second time-frequency resource block, and transmits a first information set; the first configuration information is used for indicating a first reference set, and any two time-frequency resource blocks in the first resource set employ a same positioning-related parameter; the first time-frequency resource block is earlier than the second time-frequency resource block in time domain; the first information set comprises a first distance, and the first distance refers to a distance from a first geographical position and a second geographical position, wherein the first geographical position is where the first node is located when transmitting the first positioning reference signal. The present disclosure provides an effective solution to the issue of sidelink positioning.

    摘要: The present disclosure provides a method and a device in a node used for wireless communication. A first node receives a first information element, the first information element being used for indicating a first reference power value; and receives a second information set, the second information set comprising a second information element, the second information element being used for indicating a second limit power value; and transmits a first radio signal with a first power value; a target receiver of the first radio signal includes a transmitter of the first information element, the first power value is related to a smaller value between the first reference power value and the second limit power value. Taking into account restrictions resulted from interference when adjusting a transmitting power of a desired signal, the present disclosure can address interferences that may occur in V2X system in unicast or groupcast transmission.

    摘要: The present invention discloses a navigation method for electric vehicles based on electricity quantity guidance of energy-storage charging piles. The electric vehicles select charging piles nearby that can meet own charging quantity demands to charge according to location information of charging piles and real-time stored electricity information of energy storage modules of the charging piles; a system using the method includes the charging piles. The navigation method and system can reasonably guide the electric vehicles to charge according to the distribution and the stored electricity of the charging piles, and can dynamically plan travel charging solutions for the electric vehicles, thereby avoiding problems that the electric vehicles stop running without electricity on the way to the charging piles and inefficiently wait for charging for a long time, so that the stored electricity of the charging piles can be reasonably distributed and utilized, and energy idleness and waste are avoided.

    摘要: Automation of microscopic pathological diagnosis relies on digital image quality, which, in turn, affects the rates of false positive and negative cellular objects designated as abnormalities. Cytogenetic biodosimetry is a genotoxic assay that detects dicentric chromosomes (DCs) arising from exposure to ionizing radiation. The frequency of DCs is related to radiation dose received, so the inferred radiation dose depends on the accuracy of DC detection. To improve this accuracy, image segmentation methods are used to rank high quality cytogenetic images and eliminate suboptimal metaphase cell data in a sample based on novel quality measures. When sufficient numbers of high quality images are found, the microscope system is directed to terminate metaphase image collection for a sample. The International Atomic Energy Agency recommends at least 500 images be used to estimate radiation dose, however often many more images are collected in order to select the metaphase cells with good morphology for analysis. Improvements in DC recognition increase the accuracy of dose estimates, by reducing false positive (FP) DC detection. A set of chromosome morphology segmentation methods selectively filtered out false DCs, arising primarily from extended prometaphase chromosomes, sister chromatid separation and chromosome fragmentation. This reduced FPs by 55% and was highly specific to the abnormal structures (≥97.7%). Additional procedures were then developed to fully automate image review, resulting in 6 image-level filters that, when combined, selectively remove images with consistently unparsable or incorrectly segmented chromosome morphologies. Overall, these filters can eliminate half of the FPs detected by manual image review. Optimal image selection and FP DCs are minimized by combining multiple feature based segmentation filters and a novel image sorting procedure based on the known distribution of chromosome lengths. Consequently, the average dose estimation error was reduced from 0.4 Gy to

A first node receives a first information element, the first information element being used for indicating a first reference power value; and receives a second information set, the second information set comprising a second information element, the second information element being used for indicating a second limit power value; and transmits a first radio signal with a first power value; a target receiver of the first radio signal includes a transmitter of the first information element, the first power value is related to a smaller value between the first reference power value and the second limit power value. Taking into account restrictions resulted from interference when adjusting a transmitting power of a desired signal, interferences that may occur in V2X system in unicast or groupcast transmission are addressed.
