Title: Apparatus and method for assigning channel of cdma communication system
Inventor: KU CHANG HWI
IPC: H04H20/00
Filed: 1998-12-07
Abstract: PURPOSE: An apparatus and a method for assigning a channel of a CDMA communication system are provided to assign a dedicated control channel and a fundamental channel through a traffic channel and assign a forward dedicated control channel by using a Quasi orthogonal code. CONSTITUTION: A type of dedicated channel to be additionally assigned by a base station and a resource state are checked to determine a channel assign mode and a channel separation value. A channel assignment message including the channel separation value and the mode determined by the base station is transmitted through a traffic channel to a mobile station. A terminal checks whether there is a channel assignment message through the traffic channel in communicating with the base station. In case that the channel assignment message has been received, a channel assignment mode and a channel separation value are determined from the received channel assignment message. A dedicated channel is assigned corresponding to the channel assignment mode on the basis of the determined channel separation value.

Title: Regulating metabolism by modifying the level of trehalose-6-phosphate
Inventor: GODDIJN OSCAR JOHANNES MARIA
IPC: C12N5/06
Filed: 1997-05-02
Abstract: PURPOSE: A method for regulating a metabolism is provided to introduce or to inhibit the enzymes trehalose phosphate synthase (TPS) being capable of forming T-6-P and trehalose phosphate phosphatase (TPP) which degrades T-6-P into trehalose. CONSTITUTION: The invention lies in the field of regulation of carbon flow in the metabolism of the cell. It has been found that induction of a change in the intracellular availability of the saccharide trehalose-phosphate (T-6-P) induces modifications of the development and/or composition of cells, tissue and organs in vivo. These changes can be induced by introducing or inhibiting the enzymes trehalose phosphate synthase (TPS) which is capable of forming T-6-P and trehalose phosphate phosphatase (TPP) which degrades T-6-P into trehalose. The carbon flow through the glycolysis will be stimulated by a decrease in the intracellular level of T-6-P.
