remote sensing using small spacecraft arising from multi-objective economic activity problems is getting more and more developed. these satellites require very accurate pointing to specific locations of interest, with high reliability and small latency. the space borne imaging systems always attempted to achieve the highest ground resolution possible with the available technology at the given t...
In this paper, a new steganography scheme with high embedding payload and good visual quality is presented. Before embedding process, secret information is encoded as block using Reed-Muller error correction code. After data encoding and embedding into the low-order bits of host image, modulus function is used to increase visual quality of stego image. Since the proposed method is able to embed...

Therapeutic nanoparticles (TNPs) aim to deliver drugs more safely and effectively to cancers, yet clinical results have been unpredictable owing to limited in vivo understanding. Here we use single-cell imaging of intratumoral TNP pharmacokinetics and pharmacodynamics to better comprehend their heterogeneous behaviour. Model TNPs comprising a fluorescent platinum(IV) pro-drug and a clinically t...
Carbohydrate-based materials offer exciting opportunities for drug delivery. They present readily available, biocompatible components the construction of macromolecular systems which can be loaded with cargo, and enable targeting a payload to particular cell types through carbohydrate recognition events established in biological systems. These additionally engineered respond environmental stimu...
Coronagraphic space telescopes require wavefront control systems for high-contrast imaging applications such as exoplanet direct imaging. High-actuator-count MEMS deformable mirrors (DM) are a key element of these wavefront control systems yet have not been flown in space long enough to characterize their on-orbit performance. The MEMS Deformable Mirror CubeSat Testbed is a conceptual nanosatel...
