Abstract: A water cooling head with sparse and dense fins, including a main body, a first fin set and a second fin set. Wherein a chamber is formed inside the main body, the main body has a first plate and a second plate, the main body forms an inlet channel and an outlet channel, so that the cooling water passes through the chamber. The first fin set and the second fin set are arranged in the chamber, and the first fin set and the second fin set are connected to the first plate respectively. The first fin set comprises several first fins spaced apart, the first fins divide the chamber to form several first channels. The second fin set comprises several second fins spaced apart, the second fins divide the chamber to form several second channels. The water cooling head can increase the overall heat sinking efficiency.

Abstract: A memory sector with trimmed reference currents, including eight unit cells corresponding to an even word line and eight unit cells corresponding to an odd word line, and each unit cell has erased state and programmed state, wherein the logic state of unit cell corresponding to the odd word line is determined by a first reference current based on cell currents of the 8 unit cells corresponding to the even word line in programmed state and cell currents of the eight unit cells corresponding to the odd word line in erased state, and the logic state of unit cell corresponding to the even word line is determined by a second reference current based on cell currents of the eight unit cells corresponding to the even word line in erased state and cell currents of the 8 unit cells corresponding to the odd word line in programmed state.

Abstract: A system and method for quantitative imaging using a magnetic resonance imaging (MRI) system is disclosed. The method includes generating a steady-state pulse sequence on the MRI system, performing the pulse sequence to acquire magnetic resonance (MR) signals from a volume of the subject with two or more scans, representing physical parameters of the subject in relation with the MR signals through equations, generating values of the physical parameters of the subject, and generating a report indicating the physical parameters. The pulse sequence can sample two or more magnetization pathways of MR signals and at least one scan parameter of the pulse sequence changes from scan to scan.

Abstract: An aspect-oriented system includes a way to access both local and remote advice that is consistent with the modularity concerns of an aspect-oriented program. During compilation of the aspect-oriented program, a weaver determines whether advice referenced by an aspect is local or remote. If the advice is local, the weaver applies the local advice to the base program. If the advice is remote, the weaver generates remote invocation code that may include client stubs and server code to handle the marshalling and unmarshalling of parameters. Invocations to the client stub are then inserted into the join points of the base program. At run-time, the server name and number that has the remote aspect is determined. When the client stub is invoked, the remote advice on the specified server may be accessed. The result is an improved weaver that may generate code to access remote advice in a different JVM.

Abstract: During scheduling a meeting between users of networked computers, participants are assigned to groups of different priority based on importance of participant's presence at the meeting. Proposed schedule of the meeting is confirmed with the participants in an order of priority of their groups. The meeting is scheduled on a time interval during which availability of the participants is compliant with pre-selected group attendance requirements.

Abstract: A method, apparatus and program product retrieve, in the client, class metadata of an object that is used by the computer program from a remote service, including retrieving object type data of the object, and dynamically generate on the client a proxy object for the object on the server. The object is dynamically created and resides on a server, and the type of the object is unknown to the computer program prior to retrieval of the class metadata. Furthermore, casting a type of the proxy object to a type that is specific to an interface known to the computer program without receiving any class cast exception. By doing so, the dynamically created proxy object may be utilized for remote method invocation in a distributed environment utilizing objects dynamically created on the server, often avoiding a costly deployment process and independent of any protocols.

Abstract: A method, apparatus, system, and signal-bearing medium that in an embodiment find a relationship between data in data caches and update an association cache with the relationship asynchronously from updates to the data caches. In an embodiment, a relationship occurs when a foreign key in a data cache matches a primary key in another data cache. The association cache may include information about the relationship, which in an embodiment may include an owner key and a list of one or more owned keys.
