  • Publication number: 20240143739
    Abstract: The present disclosure provides a method for intelligent obfuscation of mobile applications. The method includes: performing call detection on a method chain through aspect-oriented security to detect an abnormal call; identifying an attacked node in the method chain with respect to the abnormal call to determine a hardening location; identifying an attack means with respect to the abnormal call to determine hardening strength; selecting an automated hardening solution based on the hardening strength; and executing the selected automated hardening solution at the hardening location to control impact of the automated hardening on performance in a threshold range.

  • Publication number: 20240146014
    Abstract: The present disclosure discloses a hundred-kilowatts-level monolithic fiber laser based on auxiliary lasers and hybrid cladding pumping scheme. Multi-wavelength auxiliary lasers and a signal laser are simultaneously coupled into a core of a gain fiber, and the gain fiber provides gains for the auxiliary lasers and the signal laser under multi-wavelength cladding pumping. The multi-wavelength auxiliary lasers and the signal laser are sequentially amplified under the action of gain competition, and the amplification of signal laser is suppressed at a front segment of the gain fiber, while the signal laser is effectively amplified at a rear segment of the gain fiber after the multi-wavelength auxiliary lasers are reabsorbed; quantum defects generated are reduced, and uniformly distributed thermal loads will be achieved, and the bearing capacity of laser power is improved, thereby further achieving inhibition on the transverse mode instability effect.

  • Publication number: 20230114417
    Abstract: Steel for glass lining, comprising the following chemical elements in mass percent: C: 0.015-0.060%, Si: 0.01-0.50%, Mn: 0.20-1.5%, P: 0.005-0.10%, Al: 0.010-0.070%, Ti: 0.10-0.30%, and the balance of Fe and other inevitable impurities. The microstructure of the steel for glass lining is a ferrite or a combination of a ferrite and a cementite. In addition, also disclosed is a production method for steel for glass lining, comprising the steps of (1) smelting, refining, and continuous casting to obtain a slab; (2) heating, the heating temperature being 1050-1250° C.; (3) hot rolling, the final temperature of hot rolling being controlled to be 800-920° C.; (4) cooling; and (5) thermal treatment. The steel for glass lining has excellent machinability and low temperature toughness, and also has excellent lining performance.
