Системный подход по внутрисхемной диагностике и проектированию печатных плат для локомотивов

In the conditions of microminiaturization of electronic equipment, the issues of design of switching structures are becoming increasingly relevant. The classic solution for the switching structure of functional modules of electronic equipment (EE) are multilayer printed circuit boards - printed circuit boards consisting of several layers of dielectric with conductive patterns between the layers and on the outer sides. The main task in the design of multilayer printed circuit boards is to ensure a reliable design, as well as high quality of the transmitted signal. The relevance of research is due to the fact that today more and more electronic devices have a considerable number of elements used and strict restrictions on the dimensions of the device, which leads to the need to use multilayer printed circuit boards, including in the RF range. When designing the layers of the printed circuit board, the sequence of the arrangement of the layers of the printed tracks is established; a decision is made: which of them should be solid layers of power and earth; the value of the dielectric constant of the substrate and the distance between the printed layers are taken into account; the required dimensions of the printed tracks and the minimum width of the gaps between them are calculated. It is worth noting the influence of the choice of manufacturing technology on the design of a multilayer printed circuit board.

NCMine: Core-peripheral based functional module detection using near-clique mining.

Motivation: The identification of functional modules from protein–protein interaction (PPI) networks is an important step toward understanding the biological features of PPI networks. The detection of functional modules in PPI networks is often performed by identifying internally densely connected subnetworks, and often produces modules with “core” and “peripheral” proteins. The core proteins are the ones having dense connections to each other in a module. The difference between core and peripheral proteins is important to understand the functional roles of proteins in modules, but there are few methods to explicitly elucidate the internal structure of functional modules at gene level.Results: We propose NCMine, which is a novel network clustering method and visualization tool for the core-peripheral structure of functional modules. It extracts near-complete subgraphs from networks based on a node-weighting scheme using degree centrality, and reports subgroups as functional modules. We implemented this method as a plugin of Cytoscape, which is widely used to visualize and analyze biological networks. The plugin allows users to extract functional modules from PPI networks and interactively filter modules of interest. We applied the method to human PPI networks, and found several examples with the core-peripheral structure of modules that may be related to cancer development.Availability and Implementation: The Cytoscape plugin and tutorial are available at Cytoscape AppStore.

Broadband Packaging of Photodetectors for 100 Gb/s Ethernet Applications

The packing structure of functional modules is a major limitation in achieving a desired performance for 100 Gb/s ethernet applications. This paper presents a methodology of developing advanced packaging of photodetectors (PDs) for highspeed data transmission applications by using 3-D electromagnetic (EM) simulations. A simplified model of the PD module is first used to analyze and optimize packaging structures and propose an optimal packaging design based on the simplified model. Although a PD module with improved performance proved the success of the optimal packaging design, the simplified model could not identify other important bandwidth limitation effects. Therefore, a full 3-D EM model of PD modules is developed to predict the optical-to-electrical response of the module, and with this model, it is possible to identify a critical mode mismatch effect as another important factor of limiting the bandwidth of PD modules. After eliminating the mode mismatch effect by improving the chip-conductor-backed coplanar waveguide transition, a final optimal packaging structure is implemented for the PD module with reduced attenuation up to 100 GHz and a broader 3-dB bandwidth of more than 90 GHz. Furthermore, the PD module exhibits excellent performance under the high-speed data-transmission experiment with 107 Gb/s data rate.

Modular network self-organizing map: Can it be an artificial cortex?

This paper reports on novel developments brought by combining the self-organizing map (SOM) with a modular network. This is called modular network SOM (mnSOM). The mnSOM has an arrayed structure of functional modules aligned on a lattice, and the architecture looks similar to the column structure of our cortex. One of the advantages of the mnSOM is that the user can design the module architecture flexibly depending on the user's purpose, while the backbone algorithm of SOM is kept untouched. This advantage of mnSOM has brought us many variations and applications. In this paper, the concept of mnSOM is first introduced, and variations of mnSOM and their applications are overviewed.

Designing Gene Regulatory Networks With Specified Functions

To design and construct gene regulatory networks with specified functions, such as gene switches or gene oscillators, a precise mathematical description of the networks and their properties are developed from the viewpoint of integrated systems biology. The theoretical results provide insights into the modular structures of gene regulatory networks and their quantitative functions. Specifically, based on priori knowledge of the structure of functional modules, we use feedback system to create gene regulatory networks performing basic tasks. Two typical biological networks: positive and cyclic feedback networks are used to create functions as bistable switches or oscillators. The hybrid feedback networks are adopted to provide a variety of functional designs, which demonstrate the crucial role of interactions between biological modules

Design of genetic networks with specified functions by evolution in silico.

Recent studies have provided insights into the modular structure of genetic regulatory networks and emphasized the interest of quantitative functional descriptions. Here, to provide a priori knowledge of the structure of functional modules, we describe an evolutionary procedure in silico that creates small gene networks performing basic tasks. We used it to create networks functioning as bistable switches or oscillators. The obtained circuits provide a variety of functional designs, demonstrate the crucial role of posttranscriptional interactions, and highlight design principles also found in known biological networks. The procedure should prove helpful as a way to understand and create small functional modules with diverse functions as well as to analyze large networks.
