摘要:
A method of inhibiting the 5-lipoxygenase pathway in an animal in need thereof which comprises administering an effective, 5-lipoxygenase pathway inhibiting amount of a diaryl- substituted imidazole fused to a thiazole pyrrolidine, thiazide or piperidine ring to such animal.
摘要:
6-Aryl-2,3-dihydroimidazo[2,1-b]thiazoles and corresponding thiazines act as nucleophiles, either directly or in the form of Grignard reagents, with N-acylpyridinium salts to produce new 6-aryl-5-(N-acyl-1,4-dihydro-4-pyridyl)-2,3-dihydroimidazo-[2,1-b]thiazoles and corresponding thiazines. These are oxidized to give the corresponding pyridyl-substituted imidazo[2,1-b]thiazoles and thiazines, which are active as inhibitors of the 5-lipoxygenase pathway of arachidonic acid metabolism.

摘要:
Method and System for Utilization of an Outer Decoder in a Broadcast Services Communication System is described. Information to be transmitted is provided to a systematic portion of a plurality of transmit buffers and encoded by an outer decoder communicatively coupled to the transmit buffer. The resulting redundant bits are provided to a parity portion of each transmit buffer. The content of the transmit buffers, is multiplexed and encoded by an inner decoder to improve protection by adding redundancy. The receiving station recovers the transmitted information by an inverse process. Because a decoding complexity depends on the size of a systematic portion of the transmit buffer, reasoned compromise between a systematic portion size and number of transmit buffers yields decreased decoding complexity.
摘要:
A network function is configured to maintain a copy of a session state for an access terminal. The network function is further configured to query a session master to determine whether the session state has changed. The session master is configured to generate a response to the query that enables the network function to update the copy of the session state if the session state has changed. The access terminal may be configured to change the session state at a first network function and send a message to a second network function to indicate that the session state has been changed.
摘要:
In communications networks, network elements require knowledge of other network elements such as when they are added to or deleted from the network configuration and the resources they have available. The protocol allows network elements to communicate resource information dynamically and directly. The protocol also allows direct exchange of network configuration information between network elements for determining wireless communications network paging areas.
摘要:
A cryptosync design comprising (1) a channel identifier indicative of a particular channel via which a data packet is sent, (2) an extended time stamp indicative of a time value associated with the data packet, and (3) a counter indicative of a packet count associated with the data packet. The lengths of the extended time stamp and counter fields and the time unit for the extended time stamp are parameters that may be configured for each channel. At the sender, the extended time stamp for the cryptosync may be obtained from the System Time maintained by the sender. The counter value for the cryptosync may be provided by a counter that is maintained for the channel by the sender. The sender may include a time stamp and/or the counter value, if they are needed to derive the cryptosync at the receiver, in a header of the data packet.
摘要:
Techniques for efficient storage and retrieval of Preferred Roaming Lists are disclosed. In one aspect, PRL entries are stored in two tables. One table contains records that are common to two or more PRL entries. Another table stores any information that is unique to a PRL entry, as well as an indicator of which common record is associated with it. The common record is concatenated with the unique information to generate the uncompressed PRL entry. Various other aspects of the invention are also presented. These aspects have the benefit of reducing the memory requirements for storing a PRL. In addition, time required to download the compressed PRL is reduced.
