Abstract: An information security early warning device is provided, which includes a data capturing circuit, a memory and a processor. The processor is used for running a virtual user equipment, a virtual base station and a virtual core network, and performing the following operations: when the first data flow is detected as non-malicious and abnormal, simulating transmission of the first data flow from the virtual base station to the virtual core network, and determining whether a connection can be established; when the connection can be established, updating a setting of the anomaly detection by using the first data flow; when the connection cannot be established, selecting an error log including a first malicious procedure code from multiple detection logs generated by the virtual core network; and updating the malicious feature database by using the first malicious procedure code and the first data flow.

Abstract: A laser machining device includes a pulsed laser generator, an accommodation chamber, a bandwidth broadening unit and a pulse compression unit. The pulsed laser generator is configured to emit a pulsed laser. The accommodation chamber has a gas inlet. The bandwidth broadening unit is disposed in the accommodation chamber, and is configured to broaden a frequency bandwidth of the pulsed laser to obtain a broad bandwidth pulsed laser. The pulse compression unit is disposed in the accommodation chamber. The bandwidth broadening unit and the pulse compression unit are arranged in order along a laser propagation path, and the pulse compression unit is configured to compress a pulse duration of the broad bandwidth pulsed laser.

Abstract: A fan control circuit is installed on a fan and connected with a control source which outputs a fan starting signal to the fan control circuit based on a load state. The fan control circuit includes a switch and a control module, the switch is installed on the fan and is directly operated to switch to one of a plurality of states, and the control module is connected with the switch and a motor coil installed on the fan. The control module outputs a driving signal to the motor coil based on the fan starting signal. The driving signal and a rotating speed of the fan define a rotating speed curve. A change of the states of the switch changes a slope of the rotating speed curve of the fan.

Abstract: The identification and use of two major DNA-PKcs autophosphorylation sites. Threonine (T) 2609 and Serine (S) 2056, including antibodies specific for phosphorylated T2609 and 52056. Peptides and polynucleotides encoding same, that feature these two sites of phosphorylation. The antibodies do not bind to the unphosphorylated DNA-PKcs protein or peptide, thus providing diagnostic tools to monitor the effectiveness of treatments which target the DNA repair pathway of cancer cells, and the ability to intervene or inhibit in phosphorylation of T2609 or 52056, either through application of a drug or an antibody, to increase the radiosensitivity of cancer cells.
