摘要： An aqueous oilfield treatment fluid containing a chelating agent and an HF source is described. This fluid is effective at dissolving siliceous materials such as clays and keeping the dissolved materials in solution. In particular it is effective at preventing re-precipitation of initially-dissolved silicon as silica and therefore reduces damage to sandstones with which it is contacted. Methods are given for using this fluid for sandstone matrix stimulation, removal of clay-containing drilling fluid components and filter cakes from wellbores, sandstone acid fracturing, and gravel pack and proppant pack cleaning.

摘要： We describe methods and compositions for setting the level of gene expression in a cell. The instant invention is of an amplifier, an analog circuit. It is directly analogous to the inverting amplifier commonly used in electronics. This circuit produces an output wherein an increase in the input signal leads to a proportional decrease in the output. Similarly, a decrease in the input leads to an increase in the output signal. Here the inputs and outputs may be concentrations of intracellular molecular species. The circuit is implemented as nucleic acid constructs. By analogy with the similar circuit found in analog electronics, such a circuit is expected to have improved signal to noise ratio, improved stability, and increased accuracy. It should aid in the development of intracellular instrumentation and hence the diagnosis and treatment of disease.

摘要： Unauthorized removal of articles e.g. from a retail store, each article carrying a read/write tag, is detected by a security system having at least one point-of-sale apparatus (30) arranged to write specific data into (or erase specific data from) the tag to indicate that the article has been paid for, and a detector apparatus (40) for the or each exit of the store and arranged to read each tag to determine if the specific data has been written into (or erased from) the tag, and otherwise to initiate an alarm. The system also includes a refunds/returns detector apparatus (50) to read the tag of each article presented to it, to determine if the specific data has been written into (or erased from) the tag, and to erase (or write in) that data so that the article can be returned to stock.

摘要： A system and method for voice based social networking is disclosed. The system receives a voice message (and frequently an image) and ultimately delivers it to one or multiple users, placing it within an ongoing context of conversations. The voice and image may be recorded by various devices and the data transmitted in a variety of formats. An alternative implementation places some system functionality in a mobile device such as a smartphone or wearable device, with the remaining functionality resident in system servers attached to the internet. The system can apply rules to select and limit the voice data flowing to each user; rules prioritize the messages using context information such as user interest and user state. An image is fused to the voice message to form a comment. Additional image or voice annotation (or both) identifying the sender may be attached to the comment. Fused image(s) and voice annotation allow the user to quickly deduce the context of the comment. The system provides the means to deliver a seamless flow of a conversation without requiring user interaction to hear individual comments. Multiple conversations or parts of conversations (or both) are blended into the users acoustic channel without requiring user interaction at the level of individual comments. Advertising may also be integrated. The resulting information flow is translated into formats acceptable to the user's receiving device.

摘要： A hand-operated intracardiac echocardiography (ICE) catheter is described for flexed and rotational steering is described for improved catheter operation, control and less trauma on patients. The disclosed catheter assembly includes ultrasound transducers mounted upon a rotatable tip mounted on a distal end of a flexible elongate shaft. A set of steering lines are controlled by a steering actuator to articulate bidirectionally a distal segment of the catheter. Another steering actuator controls rotation of a torque member that, in turn is coupled to the rotatable tip. A user, through the steering actuators, affects repositioning the ultrasonic transducers by repositioning exposed control surfaces of the steering actuators lengthwise along the housing of the handle.
