        The Origin of Elements from Carbon to Uranium 

        Kobayashi, Chiaki; Karakas, Amanda I.; Lugaro, Maria (2020-09-15)
        To reach a deeper understanding of the origin of elements in the periodic table, we construct Galactic chemical evolution (GCE) models for all stable elements from C (A = 12) to U (A = 238) from first principles, i.e., ...

        Effect of geometry on the fixation strength of anterior cruciate ligament reconstruction using BASHTI technique 

        Moeinnia, Hadi; Nourani, Amir; Borjali, Amirhossein; Mohseni, Mahdi; Ghias, Narges; Korani, Hossein; Chizari, Mahmoud (2020-09-08)
        The goal of this study is to investigate the effects of tendon and cannulated drill bit diameter on the strength of the bone and site hold tendon inside (BASHTI) fixation technique for an anterior cruciate ligament (ACL) ...

        Voltage Profile and Power Quality Improvement in Photovoltaic Farms Integrated Medium Voltage Grid using Dynamic Voltage Restorer 

        Benali, Abdelkrim; Khiat, Mounir; Denai, Mouloud (2020-09-01)
        In this paper, we have presented a simulation study to analyze the power quality of three phases medium voltage grid connected with distribution generation (DG) such as photovoltaic (PV) farms and its control schemes. The ...

        Modeling, Simulation and Control of a Doubly-Fed Induction Generator for Wind Energy, Conversion Systems 

        Bensahila, Boumerid; Allali, Ahmed; Merabet Boulouiha, Houari; Denai, Mouloud (2020-09-01)
        In recent years, wind energy has become one of the most promising renewable energy sources. Various wind turbine concepts with different generator topologies have been developed to convert this abundant energy into electric ...

        Avoiding high ozone pollution in Delhi, India 

        Chen, Ying; Beig, Gufran; Archer-Nicholls, Scott; Drysdale, Will; Acton, Joe; Lowe, Doug; Nelson, Beth S; Lee, James D; Ran, Liang; Wang, Yu; Wu, Zhijun; Sahu, Saroj Kumar; Sokhi, Ranjeet S; Singh, Vikas; Gadi, Ranu; Hewitt, C. N.; Nemitz, Eiko; Archibald, Alex; McFiggins, Gordon; Wild, Oliver (2020-08-06)
        Surface ozone is a major pollutant threatening public health, agricultural production and natural ecosystems. While measures to improve air quality in megacities such as Delhi are typically aimed at reducing levels of ...

        The ram pressure stripped radio tails of galaxies in the Coma cluster 

        Chen, Hao; Sun, Ming; Yagi, Masafumi; Bravo-Alfaro, Hector; Brinks, Elias; Kenney, Jeffrey; Combes, Francoise; Sivanandam, Suresh; Jachym, Pavel; Fossati, Matteo; Gavazzi, Giuseppe; Boselli, Alessandro; Nulsen, Paul; Sarazin, Craig; Ge, Chong; Yoshida, Michitoshi; Roediger, Elke (2020-08)
        Previous studies have revealed a population of galaxies in galaxy clusters with ram pressure stripped (RPS) tails of gas and embedded young stars. We observed 1.4 GHz continuum and HI emission with the Very Large Array in ...

        From Momentum Amplituhedron Boundaries to Amplitude Singularities and Back 

        Ferro, Livia; Lukowski, Tomasz; Moerman, Robert (2020-07-28)
        The momentum amplituhedron is a positive geometry encoding tree-level scattering amplitudes in $\mathcal{N}=4$ super Yang-Mills directly in spinor-helicity space. In this paper we classify all boundaries of the momentum ...

        Robust Statistics Evidence Based Secure Cooperative Spectrum Sensing for Cognitive Radio Networks 

        Simpson, Oluyomi; Sun, Yichuang (IEEE, 2020-07-27)
        Cognitive radio networks (CRNs), an assemble of smart schemes intended for permitting secondary users (SUs) to opportunistically access spectral bands vacant by primary user (PU), has been deliberated as a solution to ...

        Energy Efficient Relay Selection Algorithm for Virtual MIMO Cooperative Networks 

        El Cheikh, Mohamad; Simpson, Oluyomi; Sun, Yichuang (IEEE, 2020-07-27)
        In this paper, we propose a distance based energy efficient multiple relay selection algorithm for cooperative virtual Multiple-Input-Multiple-Output (MIMO). The fundamentals of this method is to forward the source signal ...

        Jointly optimized echo state network for short-term channel state information prediction of fading channel 

        Luo, Qiwu; Zhou, Jian; Sun, Yichuang; Simpson, Oluyomi (2020-07-27)
        Accurately obtaining channel state information (CSI) in wireless systems is significant but challenging. This paper focuses the technique of machine-learning-based channel estimation. In particular, a jointly optimized ...
