Eccentric Dust-Ring Formation In Kozai-Lidov Gas Disks, Rebecca G. Martin, Stephen H. Lubow
Eccentric Dust-Ring Formation In Kozai-Lidov Gas Disks, Rebecca G. Martin, Stephen H. Lubow
Physics & Astronomy Faculty Research
A highly misaligned gas disk around one component of a binary star system can undergo global Kozai-Lidov (KL) oscillations for which the disk inclination and eccentricity are exchanged. With hydrodynamical simulations of a gas and dust disk we explore the effects of these oscillations on the dust density distribution. For dust that is marginally coupled to the gas (St ≈ 1), we find that the dust undergoes dynamical behavior similar to that of the gas disk but the radial distribution of dust may be very different from that of the gas. The inward radial drift of the dust is faster …

The oil and gas industry faces difficulties in optimizing well placement problems. These problems are multimodal, non-convex, and discontinuous in nature. Various traditional and non-traditional optimization algorithms have been developed to resolve these difficulties. Nevertheless, these techniques remain trapped in local optima and provide inconsistent performance for different reservoirs. This study thereby presents a Surrogate Assisted Quantum-behaved Algorithm to obtain a better solution for the well placement optimization problem. The proposed approach utilizes different metaheuristic optimization techniques such as the Quantum-inspired Particle Swarm Optimization and the Quantum-behaved Bat Algorithm in different implementation phases. Two complex reservoirs are used to investigate …

The presence of spam content in social media is tremendously increasing, and therefore the detection of spam has become vital. The spam contents increase as people extensively use social media, i.e ., Facebook, Twitter, YouTube, and E-mail. The time spent by people using social media is overgrowing, especially in the time of the pandemic. Users get a lot of text messages through social media, and they cannot recognize the spam content in these messages. Spam messages contain malicious links, apps, fake accounts, fake news, reviews, rumors, etc. To improve social media security, the detection and control of spam text are …
Preface To Topic “Build And Strengthen China’S Information Tech-System”, Guojie Li, Ninghui Sun
Preface To Topic “Build And Strengthen China’S Information Tech-System”, Guojie Li, Ninghui Sun
Bulletin of Chinese Academy of Sciences (Chinese Version)
Self-reliance and self-strengthening at high level does not depend on a single technique, but on the formation of an advantageous national tech-system, so called "country-as-a-platform". Information tech-system refers to the whole one that closely connects devices, components, complete machine, system software, middleware, and application software with a series of technical standards and intellectual property rights. We are entering the IT 3.0 era characterized by integration of human-cyber-physical world. The IT 3.0 era will certainly produce a new tech-system different from the IT 1.0 and IT 2.0 eras, which is a rare opportunity for China to build a self-reliance and self-strengthening …

Opportunities And Challenges Of Building Cpu Ecosystem With Open-Source Mode, Yungang Bao, Ninghui Sun
Bulletin of Chinese Academy of Sciences (Chinese Version)
RISC-Ⅴ has been obtained huge attentions and extensively invested over the past decade due to its exciting slogan that "Instruction Sets Want to be Free". Based on RISC-Ⅴ, we are able to build a "human community with a shared future" in the CPU chip area, although there are still many challenges. China should explore its capability to make more contributions in building the open-source chip ecosystem.
