Multiply improved positive matrix factorization for source apportionment of volatile organic compounds during the COVID-19 shutdown in Tianjin, China

Environment International, 2022
Ambient concentrations of volatile organic compounds (VOCs) vary with emission rates, meteorology, and chemistry. Conventional positive matrix factorization (PMF) loses information because of dilution variations and chemical losses. Multiply improved PMF

Carbon emission reductions, pricing and social welfare of three-echelon supply chain considering consumer environmental awareness under carbon tax policy

Frontiers in Environmental Science, 2022
With the rapid growth in carbon emissions from transport, reducing these emissions is becoming as important as reducing emissions from production. We took a transporter as a member of the supply chain system and constructed a three-echelon supply chain ...
