Effective composition in visual arts relies on the principle of movement, where the viewer’s eye is directed along subjective curves to a center of interest. We call these curves subjective because they may span the edges and/or center-lines of multiple objects, as well as contain missing portions which are automatically filled by our visual system. By carefully coordinating the shape of object...

This paper provides a coherent and comprehensive classification of simulators, using a five letter coding system, and is based on the characteristics of the user interface and the logic controller.

UPC is a promising programming model for shared-memory parallel computing on sharedand distributed-memory system architectures. Berkeley UPC, which utilizes the GASNet communication system, is one promising system aimed to develop a portable, high-performance implementation of UPC for large-scale clusters. Scalable Coherent Interface (SCI) is known for its ability to provide very low latency tr...

We report a coherence-preserving photon frequency down-conversion experiment based on difference-frequency generation in a periodically poled Lithium niobate waveguide, at the single-photon level. The coherence of the process has been demonstrated by measuring the phase coherence of pseudo single-photon time-bin qubits after frequency conversion with an interference visibility of >96 %. This in...

Observation and Control of Interfacial Defects in ZnO/ZnSe Coaxial Nanowires W.A. Bhutto, Z.M. Wu∗, Y.Y. Cao, W.P. Wang and J.Y. Kang∗ Fujian Key Laboratory of Semiconductor Materials and Applications, Department of Physics, Xiamen University Xiamen 361005, P.R. China ZnO/ZnSe coaxial nanowires with di erent ZnO core diameters were synthesized by using a two-step chemical vapor deposition. The ...

We propose an experimentally feasible scheme for topological interface engineering and show how it can be used for studies of dynamics of topologically nontrivial interfaces and perforation of defects and textures across such interfaces. The method makes use of the internal spin structure of the atoms together with locally applied control of interaction strengths to create many-particle states ...

Since version 2 of the Message Passing Interface (MPI) the MPI job has the ability to start new processes dynamically at runtime. The MPI implementation has to care for the creation of new communication channels in those situations. This work desribes the implications of dynamic process creation on an communication module for the Scalable Coherent Interface (SCI). The module is developed for th...

Metal halide perovskite semiconductors have shown great performance in solar cells, and including an excess of lead iodide (PbI2) the thin films, either as mesoscopic particles or embedded domains, often leads to improved cell performance. Atomic resolution scanning transmission electron microscope micrographs formamidinium (FAPbI3) films reveal FAPbI3:PbI2 interface be remarkably coherent. It ...
