Lead by Dr. Mostafizur Rahman, the group is part of Computer Science and Electrical Engineering Department in the University of Missouri Kansas City. The group’s aim is to explore novel computing directions to solve critical challenges in more-than-moore scaling, energy constraint designs, physically vulnerable circuits for general purpose and application specific integrated circuits, bio-medical and defense applications. The scope of research also includes computing architectures for data intensive and intelligent applications. Towards these objectives, we investigate novel materials, nanoscale devices/structures, circuits, integrations and manufacturing techniques in cohesion. The research covers all aspects from material specifics to system level design, benchmarking and prototype development at scale. Ongoing research projects include nanowire based fine-grained 3-D integrated circuits and multi-valued computing using magneto-electric devices for post-CMOS digital chips, crosstalk computing to augment CMOS, and for ultra-low power analog and high power microwave tolerant circuitry.Previous projects included 2D nanowire, Spin-Wave and Hybrid Graphene-CMOS fabrics.

研究生阶段的第一篇文章（ Crosstalk between pathways enhances the controllability of signaling networks.pdf ），近日被IET Systems Biology接受发表。感谢导师武汉大学邹秀芬教授在论文投稿和发表过程中的悉心指导，鼓励和帮助！ Published Online: http://digital-library.theiet.org/content/journals/10.1049/iet-syb.2014.0061 Abstract: The control of complex networks is one of the most challenging problemsin the fields of biology and engineering. In this study, we explored thecontrollability and control energy of several signaling networks, whichconsisted of many interconnected pathways, including networks with a bow-tiearchitecture. Based on the theory of structure controllability, we revealedthat biological mechanisms, such as cross-pathway interactions,compartmentalization, etc., make the networks easier to fully control.Furthermore, using numerical simulations for two realistic examples, we demonstratedthat the control energy of normal networks with crosstalk is lower than innetworks without crosstalk. These results indicate that the biological networksare optimally designed to achieve their normal functions from the viewpoint ofthe control theory. Our work provides a comprehensive understanding of the impactof network structures and properties on controllability. Keywords: Controllability, Signaling networks, Crosstalk, Control energy

The SiPM is effectively a densely packed 2D array of Geiger-mode APD microcells, each having individual resistive quenching and multiplexed outputs. In this way the SiPM acts as a linear, high-gain photodetector for moderate photon flux NphotonoNcells. The Metal-Resistor-Silicon (MRS) structure SiPM, produced by CPTA Russia, has been characterised and tested for scintillator light detection in medical applications such as PET. We present a summary of measurements of the devices primary operating characteristics and results of the application to scintillator readout. r 2006 Elsevier B.V. All rights reserved.

After the breakdown bias is exceeded, such thermally generated electrons undergo multiplication just like any other electron in the depletion region and therefore cannot be distinguished from real signal photoelectrons. Therefore, these thermally generated electrons are the primary source of noise and should be at the single photoelectron level. Since this noise source is discrete in the sense that it consists of pulses, it is useful to know the rate of these thermal events as a function of system threshold and SiPM bias voltage. The results for one of the SiPMs are shown in Fig. 2 and show a number of interesting things. Firstly, the rate increases as a function of bias with a maximum rate of about MHz. The structure of the different photoelectron levels can be observed and from this, it is obvious that the dark rate corresponding to two or three photoelectrons is evidence of the optical cross-talk between microcells. A rough estimate from these results, using the relative count rates at the single and double photoelectron level, is that even at the highest bias values, the optical cross-talk is less than 5%. At lower values of bias voltage, it is less than 1%. level is not simply composed of single photoelectrons as stated above. In fact, the presence of dark counts at a level
