Climate Metrics for C1–C4 Hydrofluorocarbons (HFCs) (open access)

Climate Metrics for C1–C4 Hydrofluorocarbons (HFCs)

This article looks at hydrofluorocarbons (HFCs) which are potent greenhouse gases that are potential substitutes for ozone depleting substances. The Kigali amendment lists 17 HFCs that are currently in commercial use to be regulated under the Montreal Protocol. Future commercial applications may explore the use of other HFCs, most of which currently lack an evaluation of their climate metrics. In this work, atmospheric lifetimes, radiative efficiencies (REs), global warming potentials (GWPs), and global temperature change potentials (GTPs) for all saturated HFCs with fewer than 5 carbon atoms are estimated to help guide future usage and policy decisions.

Massive MIMO Systems for 5G and beyond Networks—Overview, Recent Trends, Challenges, and Future Research Direction

This article presents a comprehensive overview of the key enabling technologies required for 5G and 6G networks, highlighting the massive MIMO systems. The authors discuss the fundamental challenges related to pilot contamination, channel estimation, precoding, user scheduling, energy efficiency, and signal detection in massive MIMO systems and discuss state-of-the-art mitigation techniques. Recent trends such as terahertz communication, ultra massive MIMO (UM-MIMO), visible light communication (VLC), machine learning, and deep learning for massive MIMO systems are outlined. Finally, future research for massive MIMO systems for 5G and beyond is discussed.

Temperature dependent rate coefficients for the gas-phase OH + Furan-2,5-dione (C4H2O3, maleic anhydride) reaction (open access)

Temperature dependent rate coefficients for the gas-phase OH + Furan-2,5-dione (C4H2O3, maleic anhydride) reaction

Authors of the article assert that rate coefficients, k1(T), for the gas-phase reaction of the OH radical with Furan-2,5-dione (maleic anhydride (MA), C4H2O3), a biomass burning related compound, were measured under pseudo first-order conditions in OH using the pulsed laser photolysis - laser induced fluorescence method over a range of temperature and bath gas pressure. Their results are compared with a previous room temperature relative rate study of the OH + MA reaction and significant discrepancy between the studies is discussed. This is the accepted manuscript version of the published article.

Land Use Simulation of Guangzhou Based on Nighttime Light Data and Planning Policies (open access)

Land Use Simulation of Guangzhou Based on Nighttime Light Data and Planning Policies

This article employs nighttime light (NTL) information as a proxy indicator of gross domestic product(GDP), and a future land use simulation model (FLUS) to simulate the land use patterns in Guangzhou from 2015 to 2018 and 2018 to 2035 by incorporating planning policies. This study demonstrates that NTL is a suitable and feasible proxy indicator of GDP for the land use simulations, providing a scientific basis for the development of urban planning and construction policy.
