Given an input graph Gin =(V,E_in), we consider the problem of designing a sparse subgraph G = (V, E) with E ⊆ E_in that supports a large matching after some nodes in V are randomly deleted. We study three families of sparse graph designs (namely, Clusters, Rings, and Erdős-Rényi graphs) and...

The acceleration of industrialization has increased the discharge of chromium-containing wastewater, posing serious threat to environment and human health. To reduce Cr(VI) in wastewater and improve resource utilization of solid waste, coal gangue and rape straw were initially used to prepare...

Herein, feedstock (pinewood, rice straw, and dairy manure) and pyrolysis temperature (300, 500, and 700 °C) were selected as the influencing factors of properties of biochar (BC) to identify the contribution of biochar’s matrix on Cr(VI) removal by BC-supported sulfidated zero-valent iron...

The formation and re-formation of the architecture profession in China largely conformed to three relatively distinct episodes. They were: the Republican and Nationalist period of early professional development, the first thirty years of the Communist regime under Mao Zedong, and the present...

This paper examines three critical episodes of Chinese spatial planning in the context of the country’s urbanization and modernization process from the late nineteenth century to the mid-twentieth century. It focuses primarily on the significance of the diffusion and assimilation of borrowed...

This paper uses the lottery search index to measure public gambling sentiment, and exams the impact of temporal changes in gambling sentiment on trading behaviour, liquidity and yield of lottery stocks. We show that investors view lottery tickets and lottery stocks as alternative investments,...
