The nurse rostering problem (NRP) is a representative of NP-hard combinatorial optimization problems. The hardness of NRP is mainly due to its multiple complex constraints. Several approaches, which are based on an evolutionary algorithm (EA) framework and integrated with a penalty-function technique, were proposed in the literature to handle the(More)
OBJECTIVE To investigate the presence of miRNA-144 in the saliva of patients with esophageal cancer and its value for early diagnosis of esophageal cancer. METHODS Saliva samples were collected form patients with esophageal cancer admitted in the Fourth Affiliated Hospital of Jinan University and the First Affiliated Hospital of Guangzhou Medical College(More)
Surfactant-enhanced remediation (SER) has been widely applied in decontaminating PAH-polluted soil. Most researches focus on evaluating washing efficiency without considering pollutants' mutual interaction. This study aims to investigate cosolubilization effect between phenanthrene (Phe) and pyrene (Pyr) in nonionic surfactant Triton X-100 (TX100) solution(More)
OBJECTIVE To investigate the effect of CD59 gene inhibition mediated by RNA interference on the proliferation and apoptosis of non-small cell lung cancer (NSCLC) GLC-P cells in vitro. METHODS Recombinant plasmids for RNA interference of CD59 gene were constructed and transfected into GLC-P cells via lipofectamine 2000. The stably transfected cells were(More)
The first example of rare earth metal-catalyzed cycloaddition of terminal alkynes to azides resulting in the formation of 1,5-disubstituted 1,2,3-triazoles is described. Preliminary studies revealed that the present cycloaddition shows unprecedented mechanistic features involving a tandem anionic cascade cyclization and anti-addition across the C≡C triple(More)
Electrokinetic-microbial remediation (EMR) has emerged as a promising option for the removal of polycyclic aromatic hydrocarbons (PAHs) from contaminated soils. The aim of this study was to enhance degradation of phenanthrene (Phe)-contaminated soils using EMR combined with biosurfactants. The electrokinetic (EK) remediation, combined with Phe-degrading(More)
