The Inferior-Olivary nucleus (ION) is a well-charted region of the brain, heavily associated with sensorimotor control of the body. It comprises ION cells with unique properties which facilitate sensory processing and motor-learning skills. Various simulation models of ION-cell networks have been written in an attempt to unravel their mysteries. However, simulations become rapidly intractable when biophysically plausible models and meaningful network sizes (100 cells) are modeled. To overcome this problem, in this work we port a highly detailed ION cell network model, originally coded in Matlab, onto an FPGA chip. It was first converted to ANSI C code and extensively profiled. It was, then, translated to HLS C code for the Xilinx Vivado toolflow and various algorithmic and arithmetic optimizations were applied. The design was implemented in a Virtex 7 (XC7VX485T) device and can simulate a 96-cell network at real-time speed, yielding a speedup of 700 compared to the original Matlab code and 12.5 compared to the reference C implementation running on a Intel Xeon 2.66GHz machine with 20GB RAM. For a 1,056-cell network (non-real-time), an FPGA speedup of 45 against the C code can be achieved, demonstrating the design's usefulness in accelerating neuroscience research. Limited by the available on-chip memory, the FPGA can maximally support a 14,400-cell network (non-real-time) with online parameter configurability for cell state and network size. The maximum throughput of the FPGA IONnetwork accelerator can reach 2.13 GFLOPS.
We analyze two deep reinforcement learning algorithms, gradient-based policy optimization and evolutionary one, by a number of visualization techniques and supplement experiments. As such techniques, filter visualizat...

A formal framework for dynamic configuration and reconfiguration of services in Telematics Architecture for Plug-and-Play (TAPAS) systems was developed. It provides representation, computation and reasoning mechanisms for semantic description and matching of required and offered capabilities and status required by a particular service system. The framework employs CIM and recently developed languages for the Semantic Web in order to provide a mechanism for human-readable and machine-comprehensible descriptions of status, capabilities, system reconfiguration plans and exchanging messages. Service installer installs a service into the system by creating corresponding actors for execution of certain roles according to obtained play configuration.
Tumor-educated platelets (TEPs) are circulating blood cells with a distinct tumor-driven phenotype and act as carriers and protectors of metastases. To date, some studies have shown that the TEPs transcriptome can be ...

This paper proposes a one-phase, two-phase commit (1-2PC) protocol that can be used to atomically commit Internet transactions distributed across sites in a wide area network. The 1-2PC protocol is characterized by its ability to dynamically select between one-phase and two-phase atomic commit protocols depending on the behavior of transactions and the system requirements. Thus, it offers the performance advantages of the one-phase atomic commit protocol whenever possible, while still providing the wide applicability of the two-phase commit protocol. This is achieved in spite of the incompatibilities between one-phase and two-phase commit protocols that lead to the general practice of having to adopt a single atomic commit protocol in any distributed database system.
