Abstract: An imaging system for use in a patient is provided. The system includes an imaging probe, a rotation assembly, and a retraction assembly. The imaging probe collects image data from a patient site and includes an elongate shaft with a proximal end and a distal portion, with a lumen extending therebetween. A rotatable optical core is positioned within the elongate shaft lumen and an optical assembly is positioned in the elongate shaft distal portion. The optical assembly directs light to tissue at the patient site and collects reflected light from the tissue. The rotation assembly connects to the imaging probe and rotates the optical assembly. The retraction assembly connects to the imaging probe and retracts the optical assembly and the elongate shaft in unison.

Abstract: Peptides derived from NKp44 protein, chimeric peptides, nucleotides encoding same and pharmaceutical compositions comprising same, are provided. Further, methods of extending the biological half-life of a protein of interest are provided.

Abstract: A system and method for determining polarization in a plurality of documents, which may be grouped in a variety of ways, for example according to publication source. The polarization may be determined according to an analysis of the document itself and/or of the publication source of the document. Optionally, topic modeling is performed on one or more documents from one or more sources as part of the above analysis. One or more topic models may then be applied for tagging one or more such documents.

Abstract: The detection and warning of microbursts, low level wind shear, and other weather disturbances, which are hazardous to aircraft operations and to the public at large, are accomplished with either an airport surveillance radar (ASR) or a multi-beam Doppler radar. ASR Doppler systems normally operate to receive one of two relatively large vertical fan beams having different elevation angles but which overlap one another so that they have equal gains at an elevation angle, called the null, at a relatively low angle, for example 5.degree.. Below this null, the low beam antenna gain exceeds that of the high beam, and conversely above it. Accordingly, by subtracting the high beam Doppler spectrum from that on the low beam, a Difference Doppler Spectrum (DDS) is produced which is positive below the null and negative above. The velocity bounds of the positive portion of the DDS provide the wind speed components at the null and at heights near the surface.
