A Stochastic Linear Programming Method for the Reliable Oil Products Supply Chain System With Hub Disruption

open access: yesIEEE Access, 2019
This paper focuses on a reliable design of oil products supply chain system, which is conductive to promote the sales of oil products. A multi-scenario MILP (Mixed Integer Linear Programming) model coupled with Monte Carlo sampling is employed for ...

Copepod manipulation of oil droplet size distribution [PDF]

open access: yesScientific Reports, 2019
AbstractOil spills are one of the most dangerous sources of pollution in aquatic ecosystems. Owing to their pivotal position in the food web, pelagic copepods can provide crucial intermediary transferring oil between trophic levels. In this study we show that the calanoidParacartia granican actively modify the size-spectrum of oil droplets.

Progress of research on leakage rate model of gas pipeline

open access: yesYou-qi chuyun, 2020
Leakage amount is an important basis for consequence assessment of gas pipeline leakage accident.Once the pipeline leakage accident occurs, the negative pressure wave will be transmitted from the leakage place to the upstream and downstream of the ...

Clinical, Histopathological, and Molecular Characterization of Pediatric MN1::ZNF341‐Associated Cancer

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT A lethal round‐cell malignancy with an MN1::ZNF341 fusion has recently been reported in three infants. Here, we describe four further tumors, three in newborns (including monozygotic twins), and one in an adolescent. Detailed clinical, radiological, and histopathological data differentiate these tumors from their main mimics, neuroblastoma and
