In recent years, ghost imaging technology, which uses a barrel detector without spatial resolution to detect and reconstruct object information separately, has become an important research object in the field of quantum optics. In this paper, based on the concrete analysis of ghost imaging algorithm on the basis of information coding and transmission, the information coding transmission is completed by combining the error-checking and error-correcting function of linear block code coding and the precise transmission function of temporal ghost imaging. This paper studied and analyzed the information transmission mechanism based on temporal ghost imaging from three aspects: feasibility, robustness and bit error rate. Based on triangular wave signal information, the simulation and experimental analysis shows that the information coding transmission mechanism improves the difficulty of decoding the code by the attacker, greatly enhances the ability of anti-interference and anti-interception, reduces the bit error rate, realizes the accurate information coding transmission, and solves the problem of the current imaging algorithm which is not feasible and the degree of reduction is not high.

Learning on data represented with multiple views (e.g., multiple types of descriptors or modalities) is a rapidly growing direction in machine learning and computer vision. Although effectiveness achieved, most existing algorithms usually focus on classification or clustering tasks. Differently, in this paper, we focus on unsupervised representation learning and propose a novel framework termed Autoencoder in Autoencoder Networks (AE~2-Nets), which integrates information from heterogeneous sources into an intact representation by the nested autoencoder framework. The proposed method has the following merits: (1) our model jointly performs view-specific representation learning (with the inner autoencoder networks) and multi-view information encoding (with the outer autoencoder networks) in a unified framework;(2) due to the degradation process from the latent representation to each single view, our model flexibly balances the complementarity and consistence among multiple views. The proposed model is efficiently solved by the alternating direction method (ADM), and demonstrates the effectiveness compared with state-of-the-art algorithms.

Pilot needs to process lots of information when operating an aircraft, and reasonable information coding can greatly improve the correct rate and speed of information identification. At present, related researches are mainly performed in the laboratory, and the experiment method for abstract simulation is often used to research single digit information coding. The research results demonstrate a lack of systematization and applicability. The present study is based upon information coding methods of human-machine interface under real time in flight simulators. Subjects are required to perform an aircraft landing and the corresponding experiment task. The correct rate and reaction time are chosen as the performance evaluation indexes, combined with eye movement data. The advantages and disadvantages of different information coding methods are also evaluated and analyzed. The experiment results demonstrate that the effect of color coding on the correct rate of information identification is not significant, but the effect on the speed of information identification is obviously significant. The study demonstrates that on a black background, red, green and yellow are suitable colors for color coding, but blue is not. The position of information on the performance of information identification is also significant. The center of the interface is better than the edge, and the left position is superior to the right. The impact of language and a person＇s mother tongue should also be considered in practical applications. The study shows that the Chinese has a higher correct rate of identification than English. As the experiment research method in the present study is based on flight simulator, the actual utility and application value can be guaranteed. The research results have the ability to offer improvements in ergonomic reference for cockpit human-machine interface design.

Aiming at the effects of visual coding on information identification under ambient illumination in aircraft cockpit, a simulation model of flight information display interface was developed for ergonomics experiment. 32 subjects participated in the character-search tasks in the experiment. Correct rate and reaction time were used as evaluation indexes to analyze visual performance. ANOVA and bilinear regression were used to determine the critical sizes of different character types under various ambient illumination levels. The results of this experiment are: the order of visual performance of character types: symbols > numbers > Chinese/English; the ambient illumination has certain effects on identification performance; supplement and correction of the classic equation are put forwards to fit the need of current visual display terminal.

Internal Redox Polarity of an Individual G-sulfurreducens Bacterial Cell Attached to an Inorganic Substrate

作者： Lebedev, Nikolai Yates, Matthew D. Griva, Igor Tender, Leonard M. US Naval Res Lab Ctr Bio Mol Sci & Engn Washington DC 20375 USA George Mason Univ Dept Math Sci Fairfax VA 22030 USA George Mason Univ Ctr Simulat & Modeling Fairfax VA 22030 USA

Bacterial cell polarity is an internal asymmetric distribution of subcellular components, including proteins, lipids, and other molecules that correlates with the cell ability to sense energy and metabolite sources, chemical signals, quorum signals, toxins, and movement in the desired directions. This ability also plays central role in cell attachment to various surfaces and biofilm formation. Mechanisms and factors controlling formation of this cell internal asymmetry are not completely understood. As a step in this direction, in the present work, we develop an approach for analyzing how information about inorganic substrate can be non-genetically coded inside an individual bacterial cell. As a model system, we use G. sulfurreducens cells attached to an inorganic mineral, mica. The approach utilizes confocal Raman microscopy, Gaussian deconvolution, and Principal Component Analysis (PCA) and allows for quick label-free identification of the molecular signature of cytochrome intracellular location and the cell to substrate binding down to the level of individual bacterial cells. Our results describe a spectroscopic signature of cell adhesion and how the information about cell adhesion can be coded inside individual bacterial cells.

For robot navigation (obstacle avoidance) we propose to use special neural network, because of its large information capacity for non correlated data. We prove this feature in contrast for correlated data in the robot task. This information is generated by a simulator and coded into neural ensembles. The coding method allows different parameters with their numeric values to be stored;it also provides similarity for close values and eliminates it in other case. The developed system combines the quality of the neural network as associative memory and the coding method to permit learning from some specific situations. So we prove the system introducing only the situation information and retrieving the appropriate maneuver for it.

We present a micro-buried spiral zone plate (MBSZP) in the lithium niobate crystal fabricated with femtosecond laser direct writing technology. The microstructures of the MBSZP are buried under the surface of the crystal, which ensures the stability of the optical performance in various refractive index environments. The optical performances of imaging and focusing capabilities were demonstrated. In addition, the experiment showed good agreement with simulation results based on the optical wave propagation method. This novel optical element will have important applications in multistate information encoding, optical manipulation, quantum communication, and computation, especially in high integration, contact coupling, and variable refractive index environments.
