Abstract: The present invention relates to a method for screening mobile terminal visual attention abnormalities in children based on multimodal data learning. A calibration video and a testing video are set up, and a head-face video of children while watching the calibration video and the testing video on smartphones is recorded, respectively. An eye-tracking estimation model is constructed to predict the fixation point location from the head-face video corresponding to the testing video frame by frame and to extract the eye-tracking features. Facial expression features and head posture features are extracted. A Long Short-Term Memory (LSTM) network is used to fuse different modal features and realize the mapping from multimodal features to category labels. In the testing stage, the head-face video of children to be classified while watching the videos on smartphones is recorded, and the features are extracted and input into the post-training model to determine whether they are abnormal.

Abstract: A modified cutinase is disclosed. The cutinase has the modified amino acid sequence of SEQ ID NO: 2, wherein the modification is a substitution of asparagine at position 181 with alanine, or substitutions of asparagine at position 181 with alanine and phenylalanine at position 235 with leucine. The modified enzyme has improved PET-hydrolytic activity, and thus, the high-activity PET hydrolase is obtained, and the industrial application value of the PET hydrolase is enhanced.

Abstract: A source-network-load-storage coordination dispatching method in a background of a coupling of renewable energy sources, including: taking an expectation of a minimum grid operating cost in a dispatching cycle as an objective function; generating an approximate value function of an output of a set for generating electricity from renewable energy sources and a user load, and constructing a source-network-load-storage coordination dispatching model with combination of the objective function; obtaining forecast data of the output of a set for generating electricity from renewable energy sources and the user load, and inputting the forecast data into the dispatching model for solving; performing iterative updating on the approximate value function, importing the approximate value function after the iterative updating into the dispatching model for iterative solving, and terminating an iterative process until a solving result satisfies a preset convergence condition; and using a solving result of a last iteration

Abstract: A well cementing method is described for improving cementing quality by controlling the hydration heat of cement slurry. By controlling the degree and/or rate of hydration heat release from cement slurry, the method improves the hydration heat release during formation of cement with curing of cement slurry, improves the binding quality between the cement and the interfaces, and in turn improves the cementing quality at the open hole section and/or the overlap section. The cementing method improves cementing quality of oil and gas wells and reduces the risk of annular pressure.

Abstract: The present invention relates to a method for preparing self-assembled silicon nanotubes (SiNTs) by a hydrothermal method. A method for preparing self-assembled SiNTs comprises forming a mixture of silicon oxide and water in a sealed container, wherein the mixture has a silicon oxide to water ratio of no more than 10% by weight. The mixture is maintained at a constant temperature and a constant pressure, and the mixture is stirred for a period of time. Self-assembled SiNTs may be formed with an average inner diameter of less than 5 nm and an average outer diameter of around 15 nm. The present invention completely utilizes non-toxic raw materials, and the materials and process do not pollute the environment, so the method satisfies the development trends of the modern industry.

Abstract: An automated tracking and control system measures the lateral displacement of a moving belt, using non-contact sensing. The displacement signal is provided to an algorithm that adjusts the tilts of the belt pulleys and steers the belt laterally. Non-contact sensors include inductive proximity sensors, which respond to the metal belt but are immune to airborne slurry and other non-metallic debris in a hostile environment typical of wafer polishing. Other non-contact sensors include shielded optical sensors. Dual sensor configurations cancel response to non-lateral displacements. Instrumentation, such as tension sensors, cylinder pressure sensors, load transducers, and limit switches, provides input to the algorithm. Independent tension signals for each belt edge verify proper functioning of, e.g., pad conditioners. User-specified belt displacements, e.g.

Abstract: A process for creating a crown shaped storage node structure, for a DRAM capacitor structure, featuring the use of a silicon oxynitride layer, underlying the crown shaped storage node structure, has been developed. A silicon oxynitride layer is placed overlying the interlevel dielectric layers that used to protect underlying DRAM elements, and placed underlying a capacitor opening in an overlying insulator layer. A selective RIE procedure is used to create the capacitor opening, in an insulator layer, with the RIE procedure terminating at the exposure of the underlying silicon oxynitride layer. After creation of the crown shaped storage node structure, in the capacitor opening, overlying the silicon oxynitride layer at the bottom of the capacitor opening, the insulator layer used for formation of the capacitor opening, is selectively removed from the regions of silicon oxynitride layer, not covered by the overlying crown shaped storage node structure, using wet etch procedures.

Abstract: This invention describes the fabrication and use of a self-aligning phase shifting mask comprised of phase shifting material formed over a patterned layer of half-tone or partially transmitting material. The interaction of light passing through the phase shifting and partially transmitting areas of the mask, the phase shifting only areas of the mask, and the non phase shifting transparent areas of the mask provides greater image resolution and depth of focus tolerance than other lithography methods including other known phase shifting techniques.
