Malware is one of the prevalent security threats. Sandboxes and, more generally, instrumented environments play a crucial role in dynamically analyzing malware samples, providing key threat intelligence results and critical information to update detection mechanisms. In this paper, we study evasive behaviors employed by authors hide malicious activity samples hinder analysis. First, collect sys...

We propose a strategy, based on domain decomposition methods , for parallelizing existing sequential simulators for solving partial diier-ential equations. Using an object-oriented programming framework, high-level parallelizations can be done in an eecient and systematical way. Concrete case studies, including numerical experiments, are provided to further illustrate this parallelization strat...

A method for a direct measurement of the exclusive Ds branching ratios and of the decay constant fDs with a systematical error better than 5% is presented. The approach is based on the peculiar vertex topology of the anti-neutrino induced diffractive charm events. The statistical accuracy achievable with a neutrino factory is estimated.

The challenges of the marketplace are met by product developers in two ways: development of innovative products and reducing product costs. Cost reduction alone is not a substitute for innovation. Cost-oriented product development is systematical engineering work, which requires an interdisciplinary approach, and needs to be efficient and effective. The costs that are of interest here are those...

Molecular machines can convert the chemical energy into mechanical work through intra- or intermolecular motions at single-molecule scale under external stimuli, such as heating, illumination, and so on. In recent decades, working mechanisms of various molecular machines, shuttles, motors, walkers, etc. have been extensively studied different ensemble experiments, where unique unexpected behavi...

A point cloud as a collection of points is poised to bring about revolution in acquiring and generating three-dimensional (3D) surface information an object 3D reconstruction, industrial inspection, robotic manipulation. In this revolution, the most challenging but imperative process could registration, i.e., obtaining spatial transformation that aligns matches two clouds acquired different coo...

In this paper, we shall describe discrete kinetic models, which serve as a novel and systematical way to regularize a mixed-type system describing the dynamical phase transitions. In the limit of zero mean free path, it is expected to provide abundant reasonable kinetic relations and nucleation criteria for constructing Riemann solvers. Some particular models have been investigated theoreticall...
