摘要:
A method and system are described herein that a employ a lost frame concealment technique for processing data frames received during transmission over a communications channel. The lost frame concealment technique involves determining whether a current data frame is a bad frame, performing source decoding on the current data frame with one or more parameters that are limited by a first set of one or more values if the current data frame is a bad frame, and performing source decoding on the current data frame with one or more parameters that are not limited if the current data frame is a good frame.

A method for implementing a service for playing multimedia information during a session termination process, applied in an IP multimedia subsystem, comprises the following steps: (1) when a party, referred to as a disconnecting party, in a session disconnects the session, a server equipment requesting a media resource function to reserve multimedia information resource for a party with which the session is disconnected by the disconnecting party, referred to as a disconnected party, and to play the multimedia information to the disconnected party; (2) when the disconnected party disconnects the session or the multimedia information playing is finished, the server equipment performing a corresponding disconnection flow to disconnect the session. With the present invention, it can be implemented that during a session termination process, if one party disconnects the session, the other party can receive multimedia information sent to it by the network, which updates the experience of the user.

The present invention discloses a method for supporting extended parameter(s) in a REFER message, applied in a system comprising a parameter proxy server that can receive and forward the REFER message; upon receiving the REFER message including the extended parameter(s), the parameter proxy server performing the following processing: storing said extended parameter(s); sending the REFER message to the indicated party of the message; upon receiving a third party message sent by said indicated party and indicated by the method parameter in the REFER message, adding the extended parameter(s) stored into the third party message; sending the third party message to said third party. With the present invention, those IMS intelligent terminals that do not support the extended parameter(s) in the REFER message can more fully utilize the REFER message to use the abundant services provided by NGN.

The invention, belongs to the field of wastewater treatment technology, is a two-phase anaerobic reactor enhanced by addition of zero valent iron (ZVI). In the reactor, 2˜4 ZVI-filling layers are settled in the middle of the anaerobic hydrolysis-acidification tank, the effluent of which is fed into the rear anaerobic methanogenic tank. The degradation of organics is effectively enhanced in the anaerobic hydrolysis-acidification tank with dosing of ZVI, which may produce more acetic acid that is a desired substrate for the subsequent methanogenesis. Meanwhile, the acidic environment of the hydrolysis-acidification tank is helpful for the dissolution of ZVI to maintain its activity. The reactor is reasonably designed with high performance and strong shock resistance in anaerobic treatment of various wastewaters. Tests in lab-scale showed that hydrolysis-acidification and methanogenesis in this combined system were significantly improved compared with a reference reactor without addition of ZVI.

The invention discloses a wastewater processing method of hydrolysis-acidification enhanced by addition of zero-valent iron (ZVI), including the following steps: 3˜6 ZVI-filling layers are settled in the middle of an anaerobic hydrolysis-acidification reactor. Excess sludge taken from sewage treatment plant using as seed sludge is added into this anaerobic hydrolysis-acidification reactor for startup and domestication. In the present invention, ZVI are added into this anaerobic hydrolysis-acidification reactor to accelerate organic matters degradation and produce more acetic acids, accompanied with higher COD removal obtained. ZVI can be protected from rust in this anaerobic biological environment due to the air isolation. Also, ZVI can enhance anaerobic hydrolysis of wastewater through reducing refractory pollutants involved in wastewaters. This novel method made the effluent from the hydrolysis-acidification reactor present less COD concentration and simpler substrate form, benefiting for the following anaerobic methanogenesis or aerobic treatment.

摘要:
This invention pertains to the discovery that stem cells (e.g., bone marrow stem cells) transplanted directly into a testicular environment are transdifferentiated into bona fide Sertoli cells, and/or Leydig cells, and/or and germ cells. This provides a mechanism for the treatment of male infertility and/or testosterone deficiency. Thus, in one embodiment, this invention provides a method of treating infertility or testosterone deficiency in a male mammal. The method typically involves implanting stem cells into the testes of the mammal whereby the stem cells differentiate into germ cells and/or Sertoli cells and/or Leydig cells thereby reducing infertility and/or testosterone deficiency.
