Abstract: An experimental device and method for simulating a subsurface erosion process is disclosed, including a constant-pressure water supply device, a subsurface erosion generator, and a water-soil collection device. The constant-pressure water supply device and the subsurface erosion generator communicate with each other by a pipeline. The constant-pressure water supply device is used to simulate a natural water flow in subsurface erosion. The subsurface erosion generator is used to carry sand and display the occurrence process of water-soil subsurface erosion. The water-soil collection device is used to collect soil and water loss data required for an experiment. In accordance with the experimental device, the water-soil subsurface erosion process can be accurately displayed, a water pressure can be adjusted as needed, and a height between the constant-pressure water supply device and the erosion generator can be adjusted to simulate the terrain.

Abstract: Methods, systems, and devices are disclosed for low noise and high efficiency photoelectric amplification based on cycling excitation process (CEP). In some aspects, a device for amplifying signals of light-induced photocurrent includes an anode connected to a positive terminal of a voltage source; a disordered material layer coupled to the anode, wherein the disordered material layer is structured to have a thickness of 100 nm or less; and a cathode coupled to the disordered material layer and connected to a negative terminal of the voltage source, in which the device is operable to amplify photoexcited carriers based on photon absorption to produce an external quantum efficiency of the device that is at least 100%.

Abstract: This relates generally to intelligent automated assistants and, more specifically, to provide intelligent visualization of snippet information. An example method includes receiving a user request and in response to receiving the user request, determining a response for the user request, determining a format for a visual representation of the response, identifying one or more virtual objects based on the format for the visual representation of the response, determining a size for each of the one or more virtual objects based on context information associated with the response, and displaying the one or more virtual objects within a background environment based on the size for each of the one or more virtual objects and geometry of the background environment.
