The efficiency of liposome-mediated gene delivery is greatly enhanced by appropriate decoration of vehicles with cell-specific targeting ligands. However, liposome-DNA complexes may still be opsonized in serum thus ablating any advantage gained. A stealth aspect may therefore be conferred on complexes by poly(ethylene glycol) (PEG) grafting. Here, we examined the effect that degree of PEGylatio...

Using audit trail data for a sample of NYSE firms we show that medium-size trades are associated with a disproportionately large cumulative stock price change relative to their proportion of all trades and volume. This result is consistent with the predictions of Barclay and Warner’s (1993) stealth-trading hypothesis. We find that the source of this disproportionately large cumulative price imp...

The available DNA sequence data on an African green monkey simian cytomegalovirus virus (SCMV)-derived stealth adapted virus are summarized. The data provide important insight into a generic mechanism by which viruses avoid effective immunological recognition by the cellular immune system. This process is termed stealth adaptation and comprises the deletion or mutation of the relatively few vir...

the use of liposome as an adjuvant and a vaccine carrier has been cited previously in the literature. it has also been shown to be effective in enhancing the immunogenicity of vaccine candidates. balb/c mice immunized subcutaneously with outer membrane protein (omp) of brucella abortus s19 vaccine strain entrapped in a commercial cationic liposome (s19-omp-liposome) for vaccine delivery, showed...

Abstract Background Cosmeceuticals are cosmetic products with biologically active components that have drug-like benefits. currently rapidly growing segments encompassing the personal care industry and numerous topical cosmetics-based therapies for treating different skin conditions. The barrier nature of causes limitations to treatment. effectiveness this cosmeceutical product has been enhance...

A temporal phase mask encryption method is proposed and experimentally demonstrated to improve the security of the stealth channel in an optical steganography system. The stealth channel is protected in two levels. In the first level, the data is carried by amplified spontaneous emission (ASE) noise, which cannot be detected in either the time domain or spectral domain. In the second level, eve...

The ability to distract opponents is a key mechanic in many stealth games. Existing search-based approaches to stealth analysis, however, focus entirely on solving the non-detection problem, for which they rely on static, ahead-of-time models of guard movements that do not depend on player interaction. In this work we extend and optimize an approach based on heuristic search of stealth games to...

A distinctive feature of intelligent game-based learning environments is their capacity for enabling stealth assessment. Stealth assessments gather information about student competencies in a manner that is invisible, and enable drawing valid inferences about student knowledge. We present a framework for stealth assessment that leverages deep learning, a family of machine learning methods that ...

Controlling and managing rights of digital contents has been becoming very critical in cloud-based consumer entertainment devices. The kernel-level digital rights management (DRM) software can offer stronger protection of digital contents. For effectively preventing unauthorized copying, the rootkit stealth technologies may be employed in consumer electronics (CE) environments to conceal kernel...
