Distributed robotic systems rely heavily on the publish–subscribe communication paradigm and middleware frameworks that support it, such as Robot Operating System (ROS), to efficiently implement modular computation graphs. The ROS 2 executor, a high-level task scheduler which handles messages, is performance bottleneck. We extend ros2_tracing, framework with instrumentation tools for real-time ...

With the rapid development of network technology, traditional defense “mending fold after sheep have been stolen” cannot accurately prevent various potential threats and attacks in cyberspace. At same time, cyberspace mimic (CMD) makes system uncertain dynamic time space to effectively defend against attacks. As key technology CMD, scheduling algorithm still needs be improved reliability active...

The fundamental role of autonomous agents in managing activities of space systems has emerged some years ago with the NASA’s Remote Agent Experiment. However, the possible advantages of employing multiple agents to manage activities on a single space system are largely unexplored. This paper gives a contribution in this direction by presenting the design and the experimental validation of a mul...

Increasing energy costs became one of the critical issues in database centers in the recent years. The consciousness to turn towards energy-preserving technologies have put concepts like power-awareness into the spotlight. But especially databases lack the capability of managing the energy consumption while operating and past research solely focussed on improving performance characteristics. Th...

Pyroptosis is a lytic type of programmed cell death that is initiated in response to pathogenor host-derived perturbations of the cytosol. It is characterized by cell swelling, lysis, and the release of cytoplasmic content; thus restricting the replication of intracellular pathogens and attracting effector cells of the immune system. The name pyroptosis derives from the Greek pyro (fire or feve...

JavaScript is expected to be a programming language of even wider use, considering demands for more interactive web/mobile applications and deployment in server-side software. While reliability of JavaScript code will be of more importance, testing techniques for the language remain insufficient, compared to other languages. We propose a technique to automatically generate high-coverage unit te...

IL-21 is a type I cytokine that shares the common receptor gamma-chain with IL-2, IL-4, IL-7, IL-9, and IL-15. B cells are one of the lymphoid cell types whose development and function are regulated by IL-21. Depending on the interplay with costimulatory signals and on the developmental stage of a B cell, IL-21 can induce proliferation, differentiation into Ig-producing plasma cells, or apoptos...

With the increasing demand for astronomical observations, telescope systems are becoming increasingly complex. Thus, observatory control software needs to be more intelligent. It has each instrument inside observatory, finish observational tasks autonomously, and report information users if needed. We developed a distributed autonomous framework named Remote Autonomous Control System 2nd (RACS2...
