Graphene has excellent mechanical, electrical and thermal properties. Recently, graphene-metal composites have been proposed as a means to combine the properties of metals with those of graphene, leading to mechanically, electrically and thermally functional materials. The understanding of metal-graphene nanocomposites is of critical importance in developing next-generation electrical, thermal ...

We address the problem of contour detection via per-pixel classifications of edge point. To facilitate the process, the proposed approach leverages with DenseNet, an efficient implementation of multiscale convolutional neural networks (CNNs), to extract an informative feature vector for each pixel and uses an SVM classifier to accomplish contour detection. In the experiment of contour detection...

A nonlocal variational problem modelling phase transitions is studied in the framework of Young measures. The existence of global minimisers among functions with internal layers on an infinite tube is proved by combining a weak convergence result for Young measures and the principle of concentration-compactness. The regularity of such global minimisers is discussed, and the nonlocal variational...

The energy spectrum associated with scattering of 100 keV H+ ions from the outermost few atomic layers of Cu(111) in different scattering geometries provides direct evidence of trajectory-dependent electronic energy loss. Theoretical simulations, combining standard Monte Carlo calculations of the elastic scattering trajectories with coupled-channel calculations to describe inner-shell ionizatio...

Among its multiple functions, p53 is a critical regulator of TGF-beta responses. Sasai et al. (2008) now identify a new p53 inhibitory protein, XFDL156. During embryonic development, this factor is expressed in the ectoderm germ layer and maintains the pluripotency of ectodermal cells by inhibiting TGF-beta target genes that promote mesoderm specification.

geothermal energy serves as a renewable and clean energy. thanks to its great advantages such as relatively harmless, low costs and environmental friendly, it may be a good substitute for fossil fuels. in the present study, a geothermal survey is conducted in an area prone geothermal ferdows of south khorasan province in eastern iran using etm+ data landsat 7 geo-referenced to topography map in...

This paper presents a full-reference (FR) image quality assessment (IQA) method based on a deep convolutional neural network (CNN). The CNN extracts features from distorted and reference image patches and estimates the quality of the distorted ones by combining and regressing the feature vectors using two fully connected layers. Experiments are performed on the LIVE and TID2013 databases and co...

This work briefly introduces the recurrent residual network which is a combination of the residual network and the long short term memory network(LSTM). The residual network is featured by residual blocks and the LSTM as a variant of RNN, is featured by the recurrent structure and long short term-memory cells. We modify the LSTM by adding residual links between nonadjacent layers. Experiments o...

We present a method for the determination of the local concentrations of interstitial and substitutional Mn atoms and As antisite defects in GaMnAs. The method relies on the sensitivity of the structure factors of weak reflections to the concentrations and locations of these minority constituents. High spatial resolution is obtained by combining structure factor measurement and x-ray analysis i...

Spectral Textures are rendered by multi-layer texturing, where each layer provides a certain band of spatial frequencies for the final texture. Transparency channels introduce statistical dependencies between the layers. Figures 1 shows series of screenshots that illustrate the multilayer approach of spectral texturing. The left column shows the single texture layers, increasing in scale from t...
