Antibodies which specifically bind heregulin-coupled HER3, at a site distinct from the heregulin binding site, are described. These antibodies are particularly useful in treating cancer.

A heart valve prosthesis is provided having a self-expanding multi-level frame that supports a valve body comprising a skirt and plurality of coapting leaflets. The frame transitions between a contracted delivery configuration that enables percutaneous transluminal delivery, and an expanded deployed configuration having an asymmetric hourglass shape. The valve body skirt and leaflets are constructed so that the center of coaptation may be selected to reduce horizontal forces applied to the commissures of the valve, and to efficiently distribute and transmit forces along the leaflets and to the frame. Alternatively, the valve body may be used as a surgically implantable replacement valve prosthesis.

There are provided methods and systems for transferring multimedia content using an existing digital sound transfer protocol. A system for processing multimedia content for transfer over one or more networks includes a transformation device (211) and a reconstruction device (251). The transformation device (211) is for transforming a multimedia file into a sound file for subsequent transfer over the one or more networks using an existing digital sound transfer protocol. The multimedia file represents the multimedia content. The reconstruction device (251) is for reconstructing the multimedia content from the sound file, after the sound file has been transferred.
摘要:
A processor is disclosed including several features allowing the processor to simultaneously execute instructions of multiple conditional execution instruction groups. Each conditional execution instruction group includes a conditional execution instruction and a code block specified by the conditional execution instruction. In one embodiment, the processor includes multiple registers for storing marking data pertaining to a number of instructions in each of multiple execution pipeline stages. In another embodiment, the processor includes write enable logic and an execution unit. The write enable logic produces write enable signals dependent upon received attributes, and the execution unit saves results of instructions of conditional execution instruction groups dependent upon the write enable signals.

A control system and method for ensuring proper closure of a dual swing gate. The control system employs position sensors for monitoring the position of each gate arm. A “differential position” is maintained between the arms during closing to ensure proper sequencing. The control system regulates the speed of the master arm and the slave arm to ensure that the differential position is maintained throughout the closure process.

The invention relates to the modelling and design of early warning systems for detecting medical conditions using physiological responses. The device comprises sensors for monitoring physiological parameters such as skin impedance, heart rate, and QT interval of a patient, means for establishing when those parameters change, the rate of change of the parameters, and a neural network processor for processing the information obtained by the sensors. The neural network processor is programmed with a fast learning algorithm. When the neural network establishes that a physiological condition is present in the patient an alarm signal will be generated. The invention extends to a method of non-invasive monitoring of a person using a neural network programmed with a fast learning algorithm. A non-invasive hypoglycaemia monitor is specifically described.

An apparatus is disclosed that includes a carrier structure and an optical coupling arrangement. The carrier structure is made of a silicon material and allows for the packaging and integrating of microphotonic devices onto a single chip. The optical coupling mechanism enables laser light to be coupled into and out of a microphotonic resonant disk integrated on the carrier. The carrier provides first, second and third cavities that are dimensioned so as to accommodate the insertion and snug fitting of the microphotonic resonant disk and first and second prisms that are implemented by the optical coupling arrangement to accommodate the laser coupling.

A storage device is particularly suitable for mounting to aluminum or fiberglass step ladders. A mounting assembly on one side of a planar member includes a track into which one leg of the ladder is fitted, and resilient clips that snap over the other leg of the ladder. A support member rests on a cross bar of the ladder. Storage bins are provided on the second side of the planar member. The storage bins may include covers that can be latched into the open or closed position. The storage device is able to remain in place on a step ladder even when the step ladder is folded up.
