We employ the difference-in-difference and synthetic control methods to investigate capitalization effect of hosting G20 Summit on land market, based China’s transaction dataset from 2011 2019. find that has a significant positive prices in host city, increasing by over 22.6% compared comparable cities. The impact is larger post-G20 period than preparation period. Further, heterogeneous distrib...

What kind of leadership role is China playing in the G20? How has this evolved over time, particularly with recent global crises created by COVID-19 pandemic? In addition, will China’s rising providing badly needed public goods reinforce its rivalry a declining US, present opportunity co-leading BRICS counterparts, or mediate and foster co-operative solutions among all? This study seeks to addr...

Signature-tagged mutants of Desulfovibrio desulfuricans G20 were screened, and 97 genes crucial for sediment fitness were identified. These genes belong to functional categories including signal transduction, binding and transport, insertion elements, and others. Mutants with mutations in genes encoding proteins involved in amino acid biosynthesis, hydrogenase activity, and DNA repair were furt...

Abstract Transparency in global value chains of materials, fuels, and food is critical for the implementation sustainability policies. Such policies should be led by G20, who represent more than 80% material, fuel, consumption. Multi-regional input–output analysis plays an important role consumption-based assessment, including supply their environmental impacts. However, previous accounting sch...

The concept of blue marble health emerged as a novel framework for global health in 2013 [1, 2]. Succinctly put, today most or at least one-half of the world’s neglected diseases occur among the poor living in wealthy countries, especially in the group of 20 (G20) nations and Nigeria [1–4]. Based on data mostly compiled and released by theWHO (and other published sources), approximately one-hal...

The mineralization of organic matter in anoxic environments relies on the cooperative activities of hydrogen producers and consumers obligately linked by interspecies metabolite exchange in syntrophic consortia that may include sulfate reducing species such as Desulfovibrio. To evaluate the metabolic flexibility of syntrophic Desulfovibrio to adapt to naturally fluctuating methanogenic environm...
