Abstract: A device and method and computer readable medium for resisting downgrade attacks. User equipment includes a memory having instructions stored thereon and a processor configured to execute the instructions stored on the memory to cause the user equipment to perform the following operations: determining a security authentication type when the user equipment is connected to a network device for the first time; and in response to determining that the security authentication type when the user equipment is connected to the network device for the first time is WPA3, applying the only-WPA3 rule; where the only-WPA3 rule only allows the user equipment to use WPA3 to access the network device, and refuses the user equipment to use other security authentication types with lower security than WPA3 to access the network device.

Abstract: The present disclosure belongs to the technical field of porous membrane material preparation, and specifically relates to a reverse osmosis composite membrane with an ultrathin desalting layer and a preparation method thereof; the intermediate layer is introduced after modifying the polysulfone base membrane, the modified polysulfone base membrane support layer may strengthen the bonding to the desalting layer through a covalent bond, and the thickness of the desalting layer is reduced to be ?10 nm, so that the desalination rate of the membrane is not greatly affected while increasing the membrane flux. Compared with the membrane having a conventional thickness of the desalting layer, the water flux of the reverse osmosis composite membrane with an ultrathin desalting layer may be increased by about 0.5 times, while the desalination rate has a small change.

Abstract: The disclosure relates to a method for fermentation integrated with separation and purification of acetone, butanol, and ethanol (ABE) or butanol alone, comprising the following steps: 1) obtaining ABE by fermentation using an acetone-butanol-producing bacterium or obtaining butanol using a butanol-producing bacterium; 2) using a “vapor-stripping-vapor-permeation” method (briefly VSVP) for online separation and purification of ABE or purifying butanol from the fermentation broth; wherein the VSVP method comprises the following steps: introducing a gas bubble into the fermentation broth comprising active cells for fermentation to vaporize ABE or Butanol; subjecting the gas along with the vaporized ABE or Butanol to a membrane separation unit to pass through the membrane; recovering ABE or Butanol, or subjecting ABE or Butanol to a next separation device.

Abstract: A method and apparatus for operating a semiconductor light source is presented. In particular there is a current regulator for regulating a current flowing through a light emitting diode device. The current regulator includes a first switch for receiving a first current flowing through the semiconductor light source and a control circuit coupled to the first switch and adapted to provide a second current proportional to the first current. The current regulator is adapted to regulate the first current using the second current.

Abstract: A power system and related methods provide sense resistor fault detection and safe operation of switching power converters and connected devices such as portable electronic devices powered by the switching power converter. The power system detects an open circuit or short circuit condition of the sense resistor and controls output current of the switching power converter to ensure safe operating conditions of the power system and connected equipment. The power system can also detect initial inrush current of the connected equipment and detect a duty cycle of the switching power converter to positively detect a short circuit condition of the sense resistor.
