Deploy and maintenance of Future LTE RAN will be more complex, time consuming, and expensive. In order to meet the requirements of operators and users, self-organization networks is introduced. As one of the most important self-optimization issues, Mobility Load Balancing ( MLB ) has received much attention until now. In this paper, we present a novel(More)
A novel quinoline-degrading strain, named K4, was isolated from activated sludge of a coking wastewater treatment plant and identified as Brevundimonas sp. on the basis of its 16s rDNA gene sequence analysis. Its optimum temperature and pH for quinoline degradation were 30 °C and pH 9.0, respectively, and during the biodegradation process, at 100 mg/L(More)
Self-organization and self-optimization of mobile wireless systems is of utmost importance to operators and vendors and investigated for 3GPP Long Term Evolution (LTE). As one of the most important self-optimization issues, Mobility Load Balancing??MLB??has received much attention until now. In this paper, we present a novel method named as TL-MLB(More)
Effluent of biotreated coking wastewater comprises hundreds of organic and inorganic pollutants and has the characteristics of high toxicity and difficult biodegradation; thus, its chemical oxygen demand cannot meet drainage standards in China. A boron-doped diamond anode was selected for advanced treatment of biotreated coking wastewater, and considering(More)
BACKGROUND Multiple stresses could cause damage to DNA and other macromolecules. RecO, belonging to the family of DNA repair proteins, plays an important part in homologous recombination and replication repair. In order to explore the role of RecO in overcoming multiple stresses, a mutant of recO deletion is constructed in Lactococcus lactis ssp. cremoris(More)
Cytosolic ascorbate peroxidase 1 (APX1) plays a crucial role in regulating the level of plant cellular reactive oxygen species and its thermolability is proposed to cause plant heat-susceptibility. Herein, several hyper-acidic fusion partners, such as the C-terminal peptide tails, were evaluated for their effects on the thermal stability and activity of(More)
We report realization of the first enantioselective Cope-type hydroamination of oximes for asymmetric nitrone synthesis. The ligand promoted asymmetric cyclopropene "hydronitronylation" process employs a Cu-based catalytic system and readily available starting materials, operates under mild conditions and displays broad scope and exceptionally high enantio-(More)
Nanoporous networks of tin-based alloys immobilized within carbon matrices possess unique structural and compositional superiorities toward lithium-storage, and are expected to manifest improved strain-accommodation and charge-transport capabilities and thus desirable anodic performance for advanced lithium-ion batteries (LIBs). Herein, a facile and(More)
H(+)-pyrophosphatase (H(+)-PPase) is a primary pyrophosphate (PPi)-energized proton pump to generate electrochemical H(+) gradient for ATP production and substance translocations across membranes. It plays an important role in stress adaptation that was intensively substantiated by numerous transgenic plants overexpressing H(+)-PPases yet devoid of any(More)
The inhibitory profiles of chilli pepper and capsaicin, as well as their relationship to the formation of heterocyclic amines (HAs) in roast beef patties were investigated using ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) combined with principal component analysis (PCA). HAs including(More)
