摘要:
A method of ameliorating degradation of radiolabeled peptides, especially radiolabeled proteins such as antibodies, by including povidone, also widely known as polyvinylpyrrolidone or PVP, as a radioprotectant in a composition containing a radiolabeled peptide is described. A radioprotectant composition and a stable peptide-radioisotope composition having povidone are also described. Ascorbic acid or other secondary stabilizers may also be added to the compositions to further enhance radioprotection.

An array antenna may include a substrate, an array of metamaterial elements including radiating elements suspended in the substrate and integrated with the array of dipoles, where the metamaterial elements include a first metal layer and a second metal layer connected by a via, an array of dipoles, a groundplane coupled with a first side of the substrate, the ground plane having a symmetric slot aperture and not contacting the array of metamaterial elements, and a stripline feed for the radiating elements, where the stripline feed passes from a groundplane first side through the symmetric slot aperture to a groundplane second side.

A composite mounting structure for a cathode ray tube is described wherein L-shaped mounting brackets are secured along the corner regions of the peripheral skirt of the cathode ray tube face panel by a steel tension band, and wherein slippage of the brackets and tension band during severe thermal or mechanical shock is minimized by the inclusion of slip-resistant foam mounting blocks between the base portions of the mounting brackets and the glass skirt portion of the face panel.

A two panel radar system is disclosed. The radar system may include a pair of AESA panels respectively positioned on either side of a central axis, wherein a pointing direction of the first AESA panel is offset by a predetermined angle in a clockwise direction with respect to the central axis and a pointing direction of the second AESA panel is offset by the predetermined angle in a counterclockwise direction with respect to the central axis. A controller may be configured for selectively activating at least one of: the first AESA panel for providing a first coverage area in a first direction offset from the central axis, the second AESA panel for providing a second coverage area in a second direction offset from the central axis, or the pair of AESA panels jointly for providing a third coverage area between the first coverage area and the second coverage area.

The present invention is directed to an interface for connecting a waveguide manifold of a transition to a stripline manifold of the transition. The interface may include a plurality of metamaterial layers, each including a metamaterial(s). The interface may further include a ground plane layer which may be connected to both the plurality of metamaterial layers and to the stripline manifold. Further, the interface may include a plurality of ground vias which may form channels through each of the layers of the interface and through the stripline manifold for providing a ground structure for the interface. The interface is further configured for forming a resonant structure which provides a low-loss, broadband conversion between a stripline mode and a waveguide mode for electromagnetic energy traversing through the interface between the waveguide manifold and the stripline manifold.

An electronically scanned array radiating element includes a ground plane layer having a pair of conductive probes. A metallization layer is coupled with the ground plane layer and includes a first asymmetric cluster including HOF scattering members and impedance-matching dipoles. A first electrically-large impedance-matching dipole is coupled with one of the conductive probes and is associated with the first asymmetric cluster. The first electrically-large impedance-matching dipole and the first asymmetric cluster may cooperate with one another to produce a signal. A second asymmetric cluster includes HOF scattering members and impedance-matching dipoles. A second electrically-large impedance-matching dipole is coupled with the other conductive probe and is associated with the second asymmetric cluster. The electrically-large impedance-matching dipole and the asymmetric cluster may cooperate with one another to produce a second signal having a polarization orthogonal to the polarization of the first signal.
