Abstract: An image acquisition method applied to a first electronic device, and the first electronic device includes N first cameras, N being an integer greater than or equal to 3. The image acquisition method includes: firstly, receiving, by the first electronic device, first position information from a second electronic device, the first position information being position information of eyes of a viewer of the second electronic device; then, selecting, by the first electronic device, K first cameras from the N first cameras based on the first position information, K being an integer greater than or equal to 2 and less than N; then, acquiring, by the first electronic device, images by using the K first cameras.

Abstract: Provided is the use of OXCT1 protein as succinyltransferase. It has been found that the OXCT1 protein serving as succinyltransferase can promote the growth of cancer cells by modulating succinylation modification of protein. Therefore, the design of related enzyme inhibitors can inhibit the activity of succinyltransferase, thereby inhibiting the occurrence and progression of cancer, thereby providing a new concept for targeted therapy.

Abstract: A laser cleaning method and device for improving uniformity of a laser cleaning surface are provided. The laser cleaning method includes: applying a peaked-top sine wave signal to a motor; controlling a galvanometer to swing in a reciprocated manner by the motor; shaping a laser beam emitted by a laser to a linear beam by the reciprocated swing of the galvanometer; and performing laser cleaning using the shaped linear beam.

Abstract: A laser cleaning system including a laser source, an energy-transferring optical fiber, a laser cleaning head, a coreless motor, a connection lens barrel, and a mirror.

Abstract: A simulation device for integrated evaluation experiment for sand control wellbore plugging and plugging removal, including a wellbore system, a whole sand control well plugging system, a local sand control well plugging system and a plugging removal system. The wellbore system simulates downhole working conditions of the sand control wellbore. Perforations of the whole sand control well plugging system and sand-filled pipe of the local sand control well plugging system are applied on the casing pipe of the wellbore system. The plugging process of the sand control well system is simulated by pumping a sand-laden slurry into the wellbore system. The plugging removal process is simulated by setting the plugging removal tool of plugging removal system through an oil tube in the wellbore system. The plugging removal effect of the plugging removal tool is analyzed and evaluated according to the reliable data measured by the pressure gauge, flowmeter, etc.
