Abstract: A hydrogen refueling station based on low-temperature and high-pressure graded hydrogen storage includes: a liquid hydrogen storage tank, n?2 hydrogen storage vessels that are low-temperature and high-pressure vessels, a booster pump and a high-pressure vaporizer, disposed between the storage tank and the storage vessels. A temperature value and a maximum pressure value of gaseous hydrogen stored in the storage vessels are Tn and Pn; when n=2, T1<T2, P1<P2; and when n?3, T1< . . . T(n-1)<Tn, P1< . . . P(n-1)<Pn. A main refueling pipe is configured to communicate the hydrogen storage vessels with the hydrogen dispenser. A refueling controller is configured to, based on an ascending order of the temperature values, sequentially control corresponding hydrogen storage vessels to communicate with the hydrogen dispenser for participation in a refueling operation. A gaseous hydrogen refueling method based on the hydrogen refueling station is further provided.

Abstract: A light-emitting substrate includes a transparent substrate; a first metal light-shielding layer, a wiring layer and light-emitting devices. The first metal light-shielding layer is disposed on the transparent substrate. The wiring layer is disposed on a side of the first metal light-shielding layer away from the transparent substrate, and the wiring layer includes circuit traces and pads. Orthographic projections of the circuit traces and the pads on the transparent substrate are all located within an orthographic projection of the first metal light-shielding layer on the transparent substrate. The light-emitting devices are disposed on a side of the wiring layer away from the transparent substrate, and electrically connected to some of the pads; and orthographic projections of the light-emitting devices on the transparent substrate are located within the orthographic projection of the first metal light-shielding layer on the transparent substrate.

Abstract: The present disclosure relates to methods and apparatus for graphics processing. For example, disclosed techniques facilitate improving bindless state processing at a graphics processor. Aspects of the present disclosure can receive, at a graphics processor, a shader program including a preamble section and a main instructions section. Aspects of the present disclosure can also execute, with a scalar processor dedicated to processing preamble sections, instructions of the preamble section to implement a bindless mechanism for loading constant data associated with the shader program. Additionally, aspects of the present disclosure can distribute the main instructions section and the constant data to a streaming processor for executing the shader program.

Abstract: A method for fabricating a three-dimensional (3D) FET sensor array includes fabricating a two-dimensional (2D) precursor field-effect transistor (FET) sensor array having a plurality of nanoscale or microscale FETs using any suitable microfabrication techniques. Each of the nanoscale or microscale FETs have a kink at which a FET channel is located. The 2D nanoscale or microscale precursor FET sensor array is caused to buckle or fold into a third dimension, also using any suitable technique.
