Abstract: A sampling device and method for evaluating ecological risk of soil in a high geological background area comprises an impact sampling mechanism, a soil layer stripping mechanism and an auxiliary support frame. The impact sampling mechanism comprises a sampling hopper with a downward opening. A connecting sliding rod is fixedly arranged on the top of the sampling hopper. An upper end of the connecting sliding rod is connected with an impact rod. The impact rod is internally provided with an impact hammer capable of reciprocating along an axis of the impact rod. The soil layer stripping mechanism comprises a stripping sliding cylinder in sliding fit with the connecting sliding rod, and a support disc. A plurality of stripping plates are connected to a lower side edge of the support disc in a sliding fit mode.

Abstract: A terminal communicates with base stations by receiving a first beacon frame sent by a first base station, the first beacon frame including first location information representing a location of the first base station. In response to one of a determination that a distance between the first location information and second location information is greater than a first predetermined threshold or a determination that a difference between first received signal strength information and second received signal strength information is greater than a second predetermined threshold, the terminal sends first information to a network server, the first information causing the network server to select a base station that transmits downlink data to the terminal. The second location information represents a location of a second base station corresponding to a second beacon frame received before the first beacon frame is received.

Abstract: Provided herein are small molecule inhibitors of NSD1, NSD2 and/or NSD3 activity, and methods of use thereof for the treatment of disease, including leukemia, breast cancer, osteosarcoma, lung and prostate cancers and other solid tumors as well as other diseases dependent on the activity of NSD1, NSD2 and/or NSD3.

Abstract: One embodiment described herein provides a system and method for adjusting the relay state of nodes in a wireless network. During operation, the system can obtain relay-state information associated with a plurality of neighboring nodes of a respective node in the wireless network. The system can identify, among the plurality of neighboring nodes, a set of relay neighbors capable of relaying messages based on the obtained relay-state information and determine a connectivity status of the set of relay neighbors. The system can then determine an expected relay state of the respective node based on a count and the connectivity status of the set of relay neighbors and can adjust a relay state of the respective node based on the expected relay state.

Abstract: Control apparatus for three phase alternating current load protection wherein each of the phases of the load is connected to a corresponding current transformer. When the load is energized by a three phase power supply the transformers induce signals which are applied to a signal detection circuit. The detection circuit controls a relay means. If any of the three power phases is lost the detection circuit is interrupted causing the relay means to drop out, whereby the load, the power supply and auxilliary circuitry, as the case may be, are protected.
