Android platform adopts permissions to protect sensitive resources from untrusted apps. However, after are granted by users at install time, apps could use these (sensitive resources) with no further restrictions. Thus, recent years have witnessed the explosion of undesirable behaviors in An important part defense is accurate analysis traditional syscall-based techniques not well-suited for Android, because they capture critical interactions between application and system.
Dynamic light scattering is a standard technique of nano-particle sizing in colloid systems. However, it difficult to measure the particle size accurately flowing dispersion, which inevitable many applications, such as on-line measurement. In this paper, we present that wave vector scattered light, averaged constant traditional technique, varies with time when particles undergoing not only random motion but also directional movement. This variation results an additional term sinc function...
The development of artificial intelligence and big data has put forward higher requirements for computing devices, metasurface-based optical devices have attracted attention due to their advantages. With the increase in capacity trend high integration, are beginning develop towards multi-dimensional among which wavelength-multiplexing is a method. Here, we propose spatial differential metasurface with honeycomb photonic structure as basic unit deal wavelength-multiplexed fields, where...
Metasurface-based optical differentiators have recently attracted attention for their potential advantages in real-time and high-throughput image processing technology. However, the existing suffer from limitations numerical aperture. Here, we propose a differential metasurface based on silicon clusters covered with polydimethylsiloxane, achieving remarkable aperture of 0.7. We numerically demonstrate proposed differentiator can perform second-order differentiation 1D spatial function enable...
