A semiconductor memory apparatus includes a bit line coupled to a plurality of memory cells, a discharge controller configured to generate a bit line discharge signal to pre-discharge the bit line before the memory cells are activated, and a bit line discharge block coupled to the bit line and configured to discharge the bit line in response to the bit line discharge signal.
Abstract:
The present invention provides a diaminopyrimidine derivative or its pharmaceutically acceptable salt, a process for the preparation thereof, a pharmaceutical composition comprising the same, and a use thereof. The diaminopyrimidine derivative or its pharmaceutically acceptable salt functions as a 5-HT4 receptor agonist, and therefore can be usefully applied for preventing or treating dysfunction in gastrointestinal motility, one of the gastrointestinal diseases, such as gastroesophageal reflux disease (GERD), constipation, irritable bowel syndrome (IBS), dyspepsia, post-operative ileus, delayed gastric emptying, gastroparesis, intestinal pseudo-obstruction, drug-induced delayed transit, or diabetic gastric atony.
Abstract:
A method for setting digital rights associated with content the method includes receiving a request from a user to access content comprising digital rights defined by a first set of attributes, identifying if the user has existing digital rights to the content, wherein the existing digital rights is defined by a second set of attributes, and modifying the existing digital rights associated with the content to include the first set of attributes. A terminal for issuing digital rights includes a digital rights management (DRM) server for issuing a rights object to a terminal or a content server; and a content server for encoding content using encryption keys issued from the DRM server and providing encoded content to the terminal in response to a content download request wherein the DRM server also issues content encryption keys to the content server.
Abstract:
The present invention relates to human monoclonal antibodies derived from human B cells present in the blood of patients who had recovered from infection with influenza A viruses, wherein the monoclonal antibodies have neutralizing activity against influenza A viruses. The anti-influenza A virus monoclonal antibody of the present invention has binding and neutralizing activities against at least one influenza A virus selected from the group consisting of influenza A virus H1, H2 and H5 subtypes, and thus it is useful for the prevention and treatment of a disease caused by the influenza A virus and is also useful for diagnosis of influenza A virus infection.
Abstract:
There are provided an ionic liquid having ether group(s) in which a copper(I) compound is included, a method for preparing the same, and a method for removing traces amounts of acetylene-based hydrocarbon compounds included in olefin by absorption or extraction using the same. When the disclosed solution is used, oxidation of Cu(I) to Cu(II) is prevented since CuX is stabilized by the ionic liquid. Thus, selective removal efficiency of acetylenic compounds is improved greatly while the removal performance is retained for a long period of time. Further, since the solution according to the present disclosure is applicable as an extractant as well as an absorbent, the associated operation is simple and apparatus cost can be decreased.
Abstract:
A semiconductor memory apparatus includes: a read current supply unit configured to supply a read current; a resistive memory cell configured to pass a current having a magnitude corresponding to a resistance value thereof in a data read mode; a voltage transfer unit coupled between the read current supply unit and the resistive memory cell and configured to transfer the read current to the resistive memory cell, wherein a voltage corresponding to the magnitude of the passed current is formed at a sensing node; and a feedback unit configured to pull-down drive a connection node, which is coupled between the voltage transfer unit and the resistive memory cell, when a voltage level of the sensing node reaches a predefined level.

Provided are an expression vector for an animal cell including a promoter, a cloning site or a polynucleotide encoding foreign product, and a transcription terminator, all of which are operably connected each other within the expression vector, in which at least one copy of human β-globin MAR sequence is attached to the 3′ terminal of the transcription terminator, and a method of expressing a foreign gene using the expression vector.
Abstract:
A process is disclosed for preparing N,N'-disubstituted urea by reacting an amine and CO/O.sub.2 mixture gas in the presence of a catalyst system comprising at least one selenium compound selected from SeO.sub.2, (CH.sub.3 O)Se(O)(OH) and (CH.sub.3 CH.sub.2 O)Se(O)(OH), and M.sub.2 CO.sub.3 (M=alkali metal) as a co-catalyst. The process enables less active aromatic amine with a low reactivity as well as an aliphatic amine to be easily transformed into disubstituted urea avoiding the use of expensive precious metal catalysts.
