Detection and Elimination of Spyware and Ransomware by Intercepting Kernel-Level System Routines

IEEE Access, 2018
Spyware is the most complex, obfuscated, and targeted class of malware, which has grown dramatically in recent years. Spyware is designed for secret, long-term, and persistent missions.

Carbon Nanocage‐in‐Microcage Structure With Tunable Carbon‐Coated Nickel as a Microwave Absorber With Infrared Stealth Property

Advancement of science
The rational design of microwave absorption (MA) material featuring light weight, wide absorption bandwidth, and infrared stealth property is crucial for military stealth and health protection but remains challenging. Herein, an innovative N‐doped carbon

All‐PEG‐Like Block Copolymers Self‐Assemble into Stealth Nanocarriers for Drug Delivery

Advanced Science, EarlyView.
Self‐assembling nanoparticles composed entirely of POEGMA are engineered by exploiting side‐chain–dependent amphiphilicity and tunable thermoresponsive behavior. These single‐material nanocarriers encapsulate diverse hydrophobic drugs with high efficiency, retain therapeutic activity, improve in vivo efficacy, and evade anti‐PEG antibodies.

Experiment on Electromagnetic Scattering Characteristics ofNb-doped ITO Coated Glass

Hangkong gongcheng jinzhan, 2018
The coating for cockpit glass is one of the important ways to realize aircraft stealth technology. The stealth characteristics of Nb-doped ITO(Indium Tin Oxides) coated glass is studied by using the RCS(Radar Cross Section) mean gain.

Beyond the Win: Pathways for Policy Implementation [PDF]

, 2016
When it comes to policy, a lot of attention is given to "the win." Whether it is something new and big like the Affordable Care Act, a piece of legislation in a large federal omnibus bill, or inclusion of critical language in a state policy, seeing the ...

Stealth Galaxies in the Halo of the Milky Way

, 2010
We predict that there is a population of low-luminosity dwarf galaxies orbiting within the halo of the Milky Way that have surface brightnesses low enough to have escaped detection in star-count surveys. The overall count of stealth galaxies is sensitive

Multifunctional Programmable Transmissive Metasurface with Phase and Amplitude Manipulation Capability

Advanced Science, EarlyView.
This work provides a multifunctional programmable transmissive metasurface with phase and amplitude manipulation capability in the sub‐6G band. By applying different coding strategies, the proposed metasurface can realize vortex beam generation, holographic imaging under phase coding mode, and multi‐beam forming in phase‐amplitude joint coding mode ...

Performance Analysis of Multi-User Optical Steganography Transmission System Based on Filtered Amplified Spontaneous Emission Noise

IEEE Access, 2019
We propose a multi-user optical steganography transmission system based on the filtered amplified spontaneous emission (ASE) noise for the first time. The stealth signal can be hidden in the public channel in the time and frequency domain.
