Abstract: A display substrate includes a plurality of sub-pixels. The display substrate further includes: a base substrate; a plurality of temperature sensors disposed on a first side of the base substrate; and a light-shielding layer disposed on a peripheral side, a side proximate to the base substrate, and a side away from the base substrate, of a temperature sensor in the temperature sensors. The temperature sensor is configured to detect a temperature of at least one of the plurality of sub-pixels. The light-shielding layer is configured to shield light emitted to the temperature sensor.

Abstract: The present invention provides compositions and methods for treating cancers with reduced or absent CDH1 using a RHOA dominant negative polypeptide or biologically active fragment thereof, and/or a nucleic acid encoding a RHOA dominant negative polypeptide or biologically active fragment thereof.

Abstract: A display panel includes a display layer, a photosensitive layer and an infrared mask. The display layer is configured to display an image, the display layer has light-transmitting portions, and the light-transmitting portions are configured to transmit infrared light. The photosensitive layer is disposed on a side of the display layer. The infrared mask is disposed on a side of the photosensitive layer proximate to the display layer, the infrared mask has hollowed-out regions, the hollowed-out regions are configured to make the infrared mask have a preset pattern, and a region in the infrared mask except the hollowed-out regions is configured to prevent transmission of the infrared light. The photosensitive layer is configured to receive infrared light passing though the hollowed-out regions and the light-transmitting portions, and convert the infrared light into an image signal.

Abstract: Disclosed are a dual-motor multi-gear hybrid transmission system and a vehicle. The dual-motor multi-gear hybrid transmission system includes an engine, a first motor, a second motor, a first clutch, a second clutch, a first planet row, a second planet row, a first input shaft, a second input shaft, a third input shaft and a brake assembly. The first input shaft is connected to the engine through the first clutch. The second input shaft is connected to the engine through the second clutch, and the second input shaft is sleeved outside the first input shaft. The first motor is connected to the engine. The second motor is connected to the first planet row through the third input shaft. The brake assembly is configured to brake the first planet row and/or the second planet row.

Abstract: The present invention provides a high-strength and high-heat-resistant bio-based polyamide composition, which consists of the following parts of materials by mass: 43.50-89.95% of bio-based polyamide resin slices; 10-50% of reinforcements; 0.01-2% of rare earth compounds; 0.01-1% of copper salt antioxidant combinations; 0.01-1% of free-radical scavengers; 0.01-0.5% of heat-conducting masterbatches; 0.01-1% of stabilizers; and 0-1% of dispersants. The advantage of the present invention is presented in that: the bio-based polyamide resin slice is prepared through a stepwise polycondensation process of pentanediamine and adipic acid, or through a stepwise polycondensation process of pentanediamine, adipic acid and terephthalic acid and the pentanediamine is prepared through fermentation of starch, so the prepared polyamide resin pertains to an environmentally-friendly engineering plastic.

Abstract: The present disclosure provides a lens. The lens includes at least two layers of glass wafers, each glass wafer is provided with a lens array including a plurality of lens units, glue is provided around a periphery of each of the lens unit, the lens units of two adjacent layers of glass wafers are correspondingly arranged one to one, and are adhered via the glue, the glass wafer is further provided with an air hole. In the lens provided by the present disclosure, through providing an air hole on the glass wafer of the lens, so that when two adjacent glass wafers are stacked via the glue, air in the sealed space can be exhausted through the air hole, and through filling glue in the air hole of the outermost layer of glass wafer, the sealing effect is achieved, which can avoid packaging defects, and improve product yield.
