Machine-readable media, methods, apparatus and system are described. In an embodiment, a model client platform may generate a file image comprising an incremental file stored on a first model block of a model storage unit of the model client platform; generate a file description image comprising file description stored on a second model block of the model storage unit, wherein the file description comprises a position of the first model block in the model storage unit; and upload the file image and the file description image to a server connecting with the model client platform. An ordinary client platform may generate an ordinary block bitmap indicating usage status for each ordinary block of an ordinary storage unit of the ordinary client platform; and receive the file description image from the server connecting with the ordinary client platform.

Techniques for IP flow mobility in a wireless data communications system, which allow for selective movement of IP data flows between different access networks supporting different access technology types. An access terminal (AT) is configured to selectively communicate using plural access technologies. Plural IP data flows are established between the AT and a first access network using a first technology type. A flow mobility trigger condition is detected, and in response, at least one IP data flow is moved to a second access network using a second technology, while maintaining at least another of the data flows to the first access network, and using the same IP address for the AT for data flows handled by both access networks, by using a mapping function between packet-filters for data flows and the access technology. The techniques may be used in conjunction with IP mobility protocols such as PMIP and CMIP.

A multistage electromagnetic purification method of molten metal, which employs a multistage separator composed of two or more multichannel straight-pass separators bonded together with inorganic high-temperature adhesive. Each stage of the separators is set up in such a manner that the region of centerline of each channel in the former separators is occupied by the sidewall of the next separators at the corresponding position therein; while simultaneously the position in the next separators becomes a region close to sidewall. The multistage separator eliminates the “dead zone” of electromagnetic separation, realizes the transformation from “weak zone” to “strong zone” of electromagnetic separation, and significantly increases removal efficiency of inclusions in the melt with great volume under the effect of induced magnetic field.

A method and apparatus is provided for transmitting a WDM optical signal. The method begins by modulating an odd number of optical channels that are each located at a different wavelength from one another with (1) a respective one of a plurality of information-bearing electrical signals that all embody the same broadcast information and (2) a respective one of a plurality of RF signals having a common functional broadcast waveform, at least one of the RF signals being out of phase with respect to remaining ones of the plurality of RF signals. Each of the modulated optical channels are multiplexed to form a WDM optical signal. The WDM optical signal is forwarded onto an optical transmission path.

Techniques for minimizing call setup latency are disclosed. In one aspect, a channel assignment message is sent with a flag to direct the use of previously negotiated service parameters. This aspect eliminates the need for service negotiation messages. In another aspect, a channel assignment message is sent with an active set identifier instead of an active set and its parameters. This aspect reduces the transmission time of the channel assignment message. In yet another aspect, call setup without paging is facilitated by a mobile station (106) sending a pilot strength measurement message between active communication sessions, such that a channel assignment message can be used for mobile station terminated call setup without the need for mobile station paging and related messages.

The invention discloses a series of Methanococcus jannaschii S-adenosylmethionine synthetase mutants with improved thermostability and high catalytic activity obtained by using gene mutation technique, characterized in that these mutants refer to an enzyme using Sequence 2 in the Sequence Listing as the reference sequence and contains at least one mutation at position 102, position 93, position 230, and position 357 and has a catalytic activity at least 70% higher than that of the wild-type S-adenosylmethionine synthetase using adenosine triphosphate (ATP) and methionine as substrates. These S-adenosylmethionine synthetase mutants can be used in the production of S-adenosylmethionine.

A device and a method for remote wake-up are provided. The device for remote wake-up includes a processing element and a network module, wherein the network module includes a connection module, a receiving module, a determination module, and a wake-up module. In the method for remote wake-up, a local host firstly logins a network server. Then, the local host maintains connection with the network server after entering a suspend mode, and thereby the network position of the local host is determined. Thereafter, the local host receives a network packet and determines if the network packet is a network wake-up packet transmitted from a remote client and through the network server and. When the network packet is a network wake-up packet, the local host returns to normal operation mode.

A method for chemical mechanical polishing of a substrate includes polishing the substrate at a stock removal rate of greater than about 2.5 Å/min to achieve a Ra of not greater than about 5.0 Å. The substrate can be a III-V substrate or a SiC substrate. The polishing utilizes a chemical mechanical polishing slurry comprising ultra-dispersed diamonds and at least 80 wt % water.
