Abstract: A method, device, terminal and computer readable storage medium for determining a cross-sectional shape of a borehole involves obtaining a plurality of logging data items as measured at a same depth of a well via a multi-arm caliper. The logging data items include pad coordinates which use a center of the multi-arm caliper as a reference point. Coordinates of a borehole center and a borehole radius at the depth of the well are obtained by using a least squares objective function with a constraint condition and according to the pad coordinates. The constraint condition is that a distance from a pad of a caliper tool to the borehole center is larger than or equal to the borehole radius. The pad positions are located outside a circle or on the circle obtained by fitting according to the least squares objective function, such that a real borehole cross-sectional shape is obtained. Measuring errors of well logging are reduced, and the reliability of the measurement of the borehole cross-sectional shape is improved.

Abstract: The present disclosure generally relates to high-performance flexible thermoelectric generators (f-TEGs) for heat concentration and dissipation. In some embodiments, the f-TEGs can be incorporated into wearable devices. The f-TEG device can include an f-TEG network of thermoelectric units that include multifunctional thin copper disks that can be used as electrodes, heat concentrators and spreaders, spacers, and flexibility enablers. Each electrode can include a spacer extending therefrom to suppress the heat loss between the hot and the cold sides through conduction and convection across a thermoelectric pillar disposed therebetween. In some embodiments, the f-TEG network can be associated with a fabric to provide good wearability and comfort even in wet thermal environments.

Abstract: An electromagnetic wave control apparatus includes an upper electrode layer, a lower electrode layer, a liquid crystal layer, and a first metamaterial layer disposed between the upper electrode layer and the lower electrode layer. The first metamaterial layer includes a first array including alignment unit structures. A first surface of the alignment unit structure is a surface that is of the alignment unit structure and that faces away from the liquid crystal layer. A length-to-width ratio of the first surface of the alignment unit structure is greater than 1. A length of the first surface, a width of the first surface, and a spacing between two adjacent alignment unit structures range from 1 nm to 5000 nm.

The method comprises: acquiring block header information of a to-be-generated block published by a mining pool; generating a random term based on a public key of the mining pool, a public key of the miner, POW of the miner and physical interaction information broadcast by other miners in the mining pool; calculating a to-be-verified hash value based on the block header information and the random term; if the to-be-verified hash value satisfies block generation condition, transmitting the to-be-verified hash value to the mining pool, so the mining pool generates the to-be-generated block after the to-be-verified hash value passes verification. In this invention, utilizing physical interaction information among miners to generate the random terms, so the original random terms which need to be generated at high-speed randomly are replaced, avoiding wasting computing power and electric power.

Abstract: In the present application, a method for assessing water shortage risk, device, computer device and storage medium are provided, wherein the method for assessing water shortage risk comprises: acquiring a volume of blue water flowing into soil of a to-be-assessed-area within a target time period, and a volume of retention water flowing into and retained in the soil of the to-be-assessed-area within the target time period; and determining a water shortage risk indicator of the to-be-assessed-area indicating a degree of water shortage risk of the to-be-assessed-area, according to a ratio of the volume of blue water to the volume of retention water. A higher ratio of the volume of blue water to the volume of retention water indicates poor ability of the soil's water to meet the demand for use and greater degree of the water shortage risk of the soil.
