Bionic adaptive camouflage material is a new artificial functional material, whose surface color can change adaptively according to the optical environments. Therefore, how reduce visual detectability of this becomes research hotspot digital stealth technology. In order clarify limitations and opportunities bionic materials in field stealth, we summarize applications current carry out prospect ...

This study evaluated the in vivo antitumor potential of the recombinant lectin from seeds of Cratylia mollis (rCramoll) expressed in Escherichia coli, free or encapsulated in stealth liposomes, using mice transplanted with sarcoma 180. rCramoll-loaded stealth liposomes (rCramoll-lipo) were formulated by hydration of the lipid film followed by cycles of freezing and thawing, and about 60% of rCr...

In recent years peer-to-peer (P2P) technology has been adopted by Internet-based malware as a fault tolerant and scalable communication medium for self-organization and survival. It has been shown that malicious P2P networks would be nearly impossible to uncover if they operated in a stealth mode, that is, using only a small constant number of fixed overlay connections per node for communicatio...

This paper addresses the issue of ISP motivation for multicast deployment. Our work is motivated by unicast applications such as on-line gaming and multimedia streaming that cannot leverage an existing multicast infrastructure and thus manage data distribution to multiple interested clients themselves. While such applications would greatly benefit from a multicast infrastructure, there is quest...

Recently , l iposomes have gained a special interest as gene delivery systems: over 30 human clinical trials for gene del ivery using cationic l iposomes have been approved; al l these del ivery methods use intratumoral, subcutaneous and other local delivery but not systemic delivery due to the toxicity of cat ionic l ipids . Stealth l iposomes (coated with polyethyleneglycol to camouflage the ...

one of the applications of nanotechnology is use of carbon nanotubes for the targeted delivery of drug molecules. to demonstrate the physical and chemical properties of biomolecules and identify new material of drug properties, the interaction of carbon nanotubes (cnts) with biomolecules is a subject of many investigations. cnts is a synthetic compound with extraordinary mechanical, thermal, el...

Rich multimedia places tremendous demands on wireless networks. Thus, it is important to use the limited bandwidth available to wireless networks as efficiently as possible. One method for efficient transfer of redundant data is multicast. Unfortunately, the use of multicast is limited due to the requirement for global deployment. Additionally, heterogeneous client speeds can further complicate...

The conference, hosted by British Pugwash, BASIC and Leicester University, brought together experts from the science, technology, academic, defence and security communities, civil society and industry to explore the nature and potency of evolving new technologies, how they may shape future warfare, particularly for the undersea battle space, what strategic challenges they will present and how m...

Transgenic seeds in both India (Bt cotton) and Brazil (glyphosate-resistant soybeans) spread widely and rapidly through farming communities outside the reach of biosafety or bioproperty institutions. Stealth transgenics are saved, cross-bred, repackaged, sold, exchanged and planted in an anarchic agrarian capitalism that defies surveillance and control of firms and states. The outcome is more p...

Poly(ethylene glycol) (PEG) is widely used in particle assembly to impart biocompatibility and stealth-like properties vivo for diverse biomedical applications. Previous studies have examined the effect of PEG molecular weight coating density on biological fate various particles; however, there are few that detail fundamental role architecture engineering bio–nano interactions. Herein, we engin...
