摘要： Provided are a paraelectric thin film structure and a high frequency tunable device with the paraelectric thin film structure. The paraelectric thin film structure has a large dielectric constant tuning rate and a low dielectric loss at a high frequency. The paraelectric thin film structure includes a perovskite ABO3 type paraelectric film formed on an oxide single crystal substrate. The paraelectric film is formed of a material selected from Ba(Zrx,Ti1-x)O3, Ba(Hfy,Ti1-y)O3, or Ba(Snz,Ti1-z)O3. Instead of the paraelectric film, the paraelectric thin film structure may include a compositionally graded paraelectric film having at least two paraelectric films formed of the selected material by varying the composition ratio x, y, or z. A high-frequency/phase tunable device employing the paraelectric thin film structure can have improved microwave characteristics and high-speed, low-power-consuming, low-cost characteristics.

摘要： A method, apparatus and computer-usable medium for using wildcards in a JMS Topic name. The method includes the steps of sending to a Java Naming and Directory Interface (JNDI) a storage message for messages that are identified by an identifier that includes a topic stock identifier and a topic wildcard indicator; and sending an implementation message from the JNDI to a middleware instructing the middleware to store new messages in any topic having the topic stock identifier. The implementation message causes the middleware to create a special topic that includes the topic stock identifier and the topic wildcard indicator, a query of all topics that include the topic stock identifier, and a generation of a reusable dynamic message flow instruction to a broker to direct future new messages from a publisher to all topics having the topic stock identifier.

摘要： A system, computer program product and method of keeping track of an attachment that has been detached from an e-mail message are provided. Generally, a table on which an attachment that has been detached from an e-mail message is cross-referenced to its storage location is used. Further, a link is inserted into the e-mail message to facilitate access to the detached attachment. If the attachment is ever moved from its storage location to a new storage location, the cross-referencing table is updated to reflect the new storage location. The link is also updated to facilitate access to the attachment at the new storage location.

摘要： An ultra-small optical/magnetic head actuator includes: a swing arm movable in a horizontal direction (tracking direction) and a vertical direction (focusing direction) and having mounted thereon a head for reading and writing information on a disk. A tracking actuator moves the swing arm in the horizontal direction (tracking direction) and a pivot hinge adjusts a radius of rotation of the swing arm and guides the movement of the swing arm in the tracking direction. A focusing actuator moves the swing arm in the vertical direction (focusing direction), wherein the focusing actuator includes a focusing coil attached under the swing arm and a Halbach magnet array disposed under the focusing coil minimizes thickness. Friction or backlash can be avoided, and non-repetitive errors can be reduced. The thickness of the ultra-small storage device can be reduced due to the use of a Halbach magnet array.

摘要： A method and service for enabling a smallest unit of variable data within a data space of a user application to be dynamically updated using an external source. The application GUI is enhanced with a dynamic update utility (DUU) that enables the data unit to be selected and linked to the broker topic. A list of available topics is presented for selection by the user, and the data unit automatically linked to the selected broker topic without requiring user knowledge of the specific linking parameters of the external source. A JMS client application is provided containing a message listener and an application writing protocol. A subscriber is defined for the data unit and subscribes to the particular event broker topic hosted at a JMS provider. When the event broker receives a publication from the data publication source, a copy of the published data is forwarded to the message listener associated with the subscriber, and the message listener provides the data to the application writing protocol. The application writing protocol then automatically overwrites the data unit with the published data.
