A data control method used in a media player system is disclosed. The media player system includes a data end and a play end connected to each other through a network. The data end includes an encoder for encoding media data. The play end includes a buffer for storing media data packets. The method includes comparing the number of media data packets stored in the buffer with a high threshold and a low threshold, decelerating the encoding by the encoder of the data end if the number of media data packets stored in the buffer is larger than the high threshold, and accelerating the encoding by the encoder of the data end if the number of media data packets stored in the buffer is smaller than the high threshold.

The invention relates to a method and device for processing a junk user. The method for processing the junk user comprises the steps that the archive data of the user are acquired, and the archive data comprise at least one of the personal information, historical approved memo and historical behavior information of the user; whether the user is an unauthentic user or not is analyzed according to the archive data; when the user is the unauthentic user, the behavior of the user is limited. According to the technical scheme, the reliability of the user is analyzed according to the archive data of the user, and therefore the behavior of the user is limited according to the reliability of the user, the threshold for the unauthentic user using a social application is increased, the harassment of the unauthentic user to a normal user is reduced, and the social application can actively recognize and shield the unauthentic user. Therefore, advertisements, political communication and other illegal information are filtered out more effectively, and high practicality is achieved.

A semiconductor device includes a gate electrode disposed on a semiconductor substrate and source / drain regions disposed at both sides of the gate electrode, the source / drain regions being formed by implanting impurities. The source / drain regions include an epitaxial layer formed by epitaxially growing a semiconductor material having a different lattice constant from that of the semiconductor substrate in a recessed position at a side of the gate electrode, and a diffusion layer disposed in a surface layer of the semiconductor substrate.

A comparator has first and second current paths, each passing from an input through a transistor, through a current source to ground, the second current path also having a reference voltage drop element coupled in series with the second input. The gates of the transistors are coupled to form a current mirror. The reference voltage drop element enables higher voltages to be input and compared to higher thresholds above an internal supply voltage level without the need for dividing resistors to reduce the input voltage. Avoiding such resistors means the power dissipation and the silicon area used can be kept lower. ESD vulnerability is reduced since the inputs are not coupled to gates of MOS transistors. Overvoltage protection across the source and gate of the second transistor can be added.

The invention discloses a digital certificate management method and system based on a block chain, equipment and a storage medium, in the method, a certificate template can be issued only after passing through a registration program, strict management and control are carried out from the root of certificate issuing, the certificate template and a sending record of each certificate can be traced, and the problem of certificate counterfeiting is thoroughly solved, the certificate inspection cost can be reduced, and the certificate inspection efficiency is improved. Before a certificate is issued and verified, a secure connection needs to be established between an applicant and an issuer and between a holder and a verifier, and the adopted DID technology provides a basis for secure communication and increases the security of certificate transmission. Besides, the certificate verifier can complete validity verification of the certificate based on the verifiable declaration provided by the holder, and the generation process of the verifiable declaration is combined with cryptographic technologies such as zero-knowledge proof and Merkel tree to selectively disclose certificate attributes, so that the privacy of the certificate holder can be ensured not to be leaked, and the security is improved.

Ischemia-reperfusion injury commonly results from any surgical procedure requiring stopping of blood supply to an organ followed by reperfusion such as in heart bypass, angioplasty or organ transplant. The invention discloses a method to harness the innate power of repetitive transient ischemia in protecting organs against imminent ischemia-reperfusion, or any patho-physiological insults. This method of optimal remote ischemic preconditioning (ORIP) comprises of utilizing a pair of programmable pneumatic cuffs that inflate / deflate alternately occluding blood circulation to each of the limbs for pre-defined time intervals. The apparatus delivers maximal ORIP dose in shortest possible time either as an EMS procedure during patient transportation to hospital, as elective pre-surgery treatment, or in critical care for preventing multiple-organ-dysfunction-syndrome. ORIP can be self-administered and remotely monitored by clinician especially in chronic patients for homeostasis of malfunctioning target organs. ORIP may also be deployed as adjunct in angioplasty, gene / stem cell heart repair therapies.

Methods and apparatus reduce coherence of an optical signal that is used to interrogate optical interferometric sensors. The optical field phasor of the interrogation source is modulated in a controlled manner to produce a broadened optical source power spectrum at the output of the source unit. The output from the source unit is launched into an optical sensor network, comprising a multiple of optical pathways from its input to the detection unit, where pairs of optical pathways form sensor interferometers. A compensating interferometer with delay difference similar to the sensor delay difference may be arranged in a serially coupled manner with the optical sensor network, either before or after the network. The coherence modulation may be performed through direct modulation of the source or through external modulation of the light with piezoelectric ring modulator, a Lithium niobate phase or intensity modulator, or an acoustooptic modulator.

A shared-nothing database management system employs a method of adding and removing a database server without significantly affecting the processing performance for accessing a table from a user or an application. A scheduler module creates a schedule which separately handles the addition of a CPU resource and the addition of a storage I / O resource, and a server is added in accordance with the created schedule. A common disk is used to remove a disk at an arbitrary timing. Further, a data region is previously subdivided on the common disk to eliminate a movement of data associated with the addition of a server.

A multi-threshold integrated circuit (IC) with reduced subthreshold leakage and method of reducing leakage. Selectable supply switching devices (NFETs and / or PFETs) between a logic circuit and supply connections (Vdd and Ground) for the circuit have higher thresholds than normal circuit devices. Some devices may have thresholds lowered when the supply switching devices are on. Header / footer devices with further higher threshold voltages and widths may be used to further increase off resistance and maintain / reduce on resistance. Alternatively, high threshold devices may be stacked to further reduce leakage to a point achieved for an even higher threshold. Intermediate supply connects at the devices may have decoupling capacitance and devices may be tapered for optimum stack height and an optimum taper ratio to minimize circuit leakage and circuit delay.
