Abstract: A low-cost and high-strength Bi-based superconducting wire/tape and a preparation method thereof, the preparation method includes: 1. subjecting a first Bi-based superconducting wire/tape to electrochemical silver reduction to remove a Ag alloy layer to obtain a second Bi-based superconducting wire/tape; and 2. subjecting the second Bi-based superconducting wire/tape to surface enhancement, such that a Cu layer is formed to obtain the low-cost and high-strength Bi-based superconducting wire/tape.

Abstract: A computing system for pixel-based automated testing of a navigable simulated environment includes one or more processors configured to execute, in a run-time inference phase, an application testing program. The application testing program includes a machine learning model trained to detect errors in the application under test. A screen image of the simulated environment is processed by an object detection module to determine if a key object is present in the screen image. If a key object is present in the screen image, the application testing program executes an object investigation module to generate investigation inputs to investigate the key object. If a key object is not present in the screen image, the application testing program executes an environment exploration module to generate an environment exploration action to be provided to the application under test as simulated user input.

Abstract: Transient techniques for electrothermal characterization of small (e.g., micro-scale or nano-scale) samples are described. These techniques overcome some of the limitations existing in conventional approaches. These transient techniques involve causing a temperature variation inside a sample, and determining a transient signal response (e.g., a voltage rise or drop) arising in the sample as a result of the temperature variation. In some embodiments, the temperature variation may be caused by allowing amplitude modulated electric current (e.g., stepped current or periodic stepped current) to flow through the sample. Alternatively, or additionally, the temperature variation may be caused by controlling a laser source to irradiate the sample. Thermal characteristics of the sample (e.g., thermal diffusivity, thermal conductivity, specific heat) can be determined based on the transient response. These transient techniques can be executed by a computer system in an automatic fashion, e.g.
