The scaffold of nanoparticles (broadly defined as having a size range of 1-100 nm) presents a convenient platform to incorporate multiple functionalities into one single particle for cancer imaging and therapeutics. Whether hollow inside or not, a single nanoparticle can encapsulate a large payload of imaging probes, anticancer drug molecules, or both. On the surface, tumor-specific targeting m...

Macrophages are innate immune cells with great phenotypic plasticity, which allows them to regulate an array of physiological processes such as host defense, tissue repair, and lipid/lipoprotein metabolism. In this proof-of-principle study, we report that macrophages of the M1 inflammatory phenotype can be selectively targeted by model hybrid lipid-latex (LiLa) nanoparticles bearing phagocytic ...

RTP Payload Format for Video Codec 1 (VC-1) Status of This Memo This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimite...

This memo describes how to carry real time text conversation session contents in RTP packets. Text conversation session contents are specified in ITU-T Recommendation T.140. Two payload formats are described. One for transmitting text on a separate RTP session dedicated for the transmission of text, and one for transmitting audio and text data within one single RTP session. Hellstrom Expires Au...

In this paper, we consider the problem of controlling multiple quadrotor robots that cooperatively grasp and transport a payload in three dimensions. We model the quadrotors both individually and as a group rigidly attached to a payload. We propose individual robot control laws defined with respect to the payload that stabilize the payload along three-dimensional trajectories. We detail the des...

TerraSAR-X, the first national German radar satellite, was launched in June 2007. It carries an X-band highresolution synthetic aperture radar instrument featuring the operational imaging modes Stripmap, ScanSAR and, particularly, Spotlight in a variety of different polarization modes. The TerraSAR-X mission completed its commissioning phase in December 2007 and started the provision of high-re...

This paper focuses on the development of an efficient distributed collaborative optimization method for the design of remote sensing small satellite mission in low earth orbit (LEO). The satellite mission requirement involves the duration in which the satellite is able to take images, send data to the ground station and the amount of information it can store. Conventionally, all at once methods...

The Imaging X-ray Polarimetry Explorer, a NASA small explorer mission, will be the first mission dedicated to x-ray polarimetry. payload consists of three identical telescopes, each comprising mirror module assembly (MMA) with polarization-sensitive detector at its focus. We describe all aspects MMA, from initial optical and mechanical design considerations meet program requirements through she...
