Natural language processing (NLP) task has achieved excellent performance in many fields, including semantic understanding, automatic summarization, image recognition and so on. However, most of the neural network models for NLP extract text a fine-grained way, which is not conducive to grasp meaning from global perspective. To alleviate problem, combination traditional statistical method deep ...

Fine-grained image recognition is a challenging computer vision problem, due to the small inter-class variations caused by highly similar subordinate categories, and the large intra-class variations in poses, scales and rotations. In this paper, we propose a novel end-to-end Mask-CNN model without the fully connected layers for fine-grained recognition. Based on the part annotations of fine-gra...

The use of molecular dynamics (MD) simulations has led to promising results unravel the atomistic origins adhesive wear, and in particular for onset wear at nanoscale surface asperities. However, MD come with a high computational cost offer access only narrow window time length scales. We propose here resort discrete element method (DEM) mitigate cost. Using DEM particles contact cohesive force...

ABSRACT A comparative study of the surface microstructural changes after fatigue in an ultrafine grained and coarse grained aluminum alloy was performed using orientation imaging microscopy (OIM). The fraction of low angle boundaries with misorientation less than 2.5 ̊ increased for both the coarse and ultrafine grained alloys. A consistent decrease in the fraction of low angle boundaries, with ...

We present a simple model which allows us to investigate the equilibrium aspects of molecular recognition between rigid biomolecules on a generic level. Using a two-stage approach, which consists of a design and a testing step, the role of cooperativity and of varying bond strength in molecular recognition is investigated. Cooperativity is found to enhance selectivity. In complexes which requir...

Concurrent data structures are provided in libraries such as Intel Thread Building Blocks and Java.util.concurrent to enable efficient implementation of multi-threaded programs. Their efficiency is achieved by using fine grained synchronization which creates less constrained interaction between the threads. This leads to a large number of possible interleavings and makes concurrent data structu...

We describe the development of a coarse-grained (CG) force field for nylon-6 (polycaprolactam) and its application to the simulation of the structure and macromolecular dynamics within cylindrical fibres formed by this polymer, having diameters in the 14–28nm range. Our CG model is based on the MARTINI force field for the non-bonded interactions and on Boltzmanninverted gas-phase atomistic simu...
