Abstract: A nano silk fibroin fibrous membrane with directional water transport and a preparation method thereof are provided. Firstly, renewable pure silk fibroin is extracted from natural silkworm cocoons. A silk fibroin film with a nanofibrous structure is prepared by an electrostatic spinning method, and a methanol treatment method is used to induce a secondary structure transformation of the silk fibroin film. Then, a spraying process is used to spray octadecyltrichlorosilane (OTS) onto the silk fibroin fibrous membrane, and a uniformly and regularly arranged mesh hydrophobic inner layer and mesh water transport channels are deposited on one side.

Abstract: A first instance obtains a code file of to-be-built software from a code repository, and obtains, from a dependency library, a dependency file needed for building the software. The first instance generates a plurality of building tasks based on a plurality of targets in the code file, where different building tasks include different targets, and indicates a plurality of instances in a resource pool to execute the plurality of building tasks in parallel by using the dependency file, to obtain execution results respectively corresponding to the plurality of building tasks, so that the first instance obtains the software through building based on the plurality of execution results. In this way, in a software building process, the first instance executes building processes in parallel for the plurality of building tasks including different targets. Compared with a manner of building targets one by one on a single node.

Abstract: The present invention provides a received signal strength (RSS)-based emergency positioning method and system for locating a target user equipment (UE). The method comprises: broadcasting sidelink signals to request UEs from surroundings to transmit identification signals; identifying a target UE based on the plurality of identification signals; estimating, by the processor, a final RSS distance of the target UE with respect to the locator based on RSS values of received uplink signals; estimating an angle of arrival for the locator; and computing location of the targe UE based on the obtained RSS distance and the obtained angle of arrival. The present invention can locate the target position without the assistance of global positioning system (GPS) and macro base station (MBS), and achieve a better localization performance than the commercial MBS and GPS-based localization approaches.

Abstract: The present disclosure relates to an optimization method of outlier data identification in a traffic emission quota allocation process. This method includes: constructing a traffic emission quota allocation model; calculating a unit output-input value for each input of each vehicle in a reference set D; identifying outlier vehicles by using a combination of isolation forest model-generalized super efficiency model; and removing final outlier vehicles from the reference set D to obtain a reference set D? with the final outlier vehicles being removed.

Abstract: Provided herein are sorbents for carbon dioxide (CO2) capture, such as from natural gas and coal-fired power plant flue gases, and uses thereof.

Abstract: Hierarchically porous graphitic (HPG) carbon is provided via improved methods. The first approach is based on forming a 3-D polymer network from a first precursor and a second precursor and carbonizing it. The carbon in the resulting carbon structure comes from the first precursor, while the second precursor volatizes to form the pores. However, the second precursor is temperature resistant, such that carbonization of the first precursor is underway when the second precursor volatizes. The second approach is based on forming a structured polymer from first and second precursors. More specifically, the second precursor forms a second polymer having a micelle structure and the first precursor forms a first polymer that coats the micelle structure of the second polymer. The structured polymer is carbonized. Here also the carbon in the resulting carbon structure comes from the first precursor, while the second precursor volatizes to form the pores.

Abstract: Polymer Pen Lithography is used to induce bioorthogonal reactions between treated surfaces and functionalized inks create a soft matter layer. Fluorescent and redox-active inks were used to demonstrate that the molecules were immobilized covalently and achieves precise control over ligand orientation and density within each feature. Finally, the utility was demonstrated by creating functional arrays of biologically active probes.
