The stability and evolution of human genetics depend on chromosomes chromosome-chromosome interactions. We wish to understand the spatial location in dividing cells order relationship between interactions further investigate role their impact cell biological behavior. In this study, we explored relative positional relationships [t(9;22) t(15;17)] B-ALL by using three-dimensional DNA fluorescent situ hybridization (3D-FISH) method. results showed that relatively stable relationships. may be...
Abstract The development of optical imaging techniques has led to significant advancements in single‐nanoparticle tracking and analysis, but these are incapable label‐free selective nanoparticle recognition. A plasmonic technology that is able identify different kinds nanoparticles water now presented. It quantifies the interferometric scattering patterns establishes relationships among refractive index, particle size, pattern both numerically experimentally. Using this approach, metallic...
Time-to-digital converter (TDC) implemented in field programmable gate array (FPGA) has been developed for years and obtained superior performance. In an application with large amount of channels, tradeoff must be weighed between performance cost if TDC is FPGA. Massive channels high event rate also lead to big challenges data transmission real time. Thus, it great significance develop time digitizers that accommodate satisfying resolution cost. this paper, a prototype sandwich structure...
In this paper, we investigated the hardware implementation of two feedforward neural networks (NNs) using a field-programmable gate array (FPGA), then used for alpha-gamma discrimination in barium fluoride (BaF <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ). The BaF detector output was sampled 1-GSPS ADC, and extracted six information pulses FPGA as input features to NNs. performance method turned out very good, false alarm rate less...
The ability to track interfacial dynamics of a single nanoparticle at the solution–solid interface is crucial for understanding physical, chemical, and biological processes, but it remains challenge. Here, we demonstrated plasmonic imaging technique that can unlabeled nanoparticles with high spatial temporal resolutions. This based on particle-induced interferometric scattering surface wave, which results in vertical sensitivity. Using this ability, tracked trajectories interacting surface,...
