The results showed a positive linear correlation between the BrdU incorporation rate and the S fraction in unperturbed 16HBE cells. Theoretical analysis indicated that only S arrest could result in a decrease in the SFN-BrdU incorporation rate. Additionally, the decrease in SFN-BrdU incorporation rate and the activation of DNA damage checkpoints further demonstrated that S arrest was induced by diethyl sulfate treatment of 16HBE cells. In conclusion, $FN-BrdU incorporation rate can be used to detecting S arrest.展开更多

These achievements have paved the way for China to enhance the quality and efficiency of growth in the new normal. China's future growth prospects are highly correlated with the 13th Five-Year Plan (2016-2020). For the 13th Five-Year Plan period, China is committed to maintaining an annual growth rate of no less than 6.5%, which is both necessary for China to build an all-round, well-off society before 2020 and consistent with the characteristics of China's current economic development stage. Meanwhile, efforts must be made to give prominence to consumption, investment, and export as drivers of growth while continuing to improve labor and capital input and efficiency which is vital to mid- and long- term economic development.展开更多

The upstream operations production and management of oil companies face numerous problems and challenges. One of the most significant aspects is to control and optimize investment. Drilling investment is an important component of development investment in drilling oil and gas wells. This paper proposes ways and countermeasures of controlling drilling cost from 3 aspects which are technology innovation, management innovation and system innovation on basis of studying drilling cost structure and influence factors analysis. The results have some guidance and exemplary significance to show how to improve production and management effect respectively on upstream operations of oil companies under new normal.展开更多

Our study findsthat great differences exist in the macroeconomic effects of different fiscal instruments, suggesting that the government should prudently select these fiscal instruments in fiscal macro-control. The simulating results of fiscal shocks show that the effect of tax cut is superior to the effect of increased spending. In the context of slowing economic growth and less potent stimulation policy, the government should transform its previous regulatory approach of fiscal policy and shift from hefty spending stimulus policy to structural tax cuts. This paper believes that China should step up the implementation of public-private partnership, increase its spending on social security, healthcare, pension and public services and facilitate the transition toward a service-based government; and that tax policy should focus on structural tax cuts on consumption to promote the transition of demand structure toward consumption-driven.展开更多

In previous literature, it was demonstrated that the irregularity of the electron phase-space orbits could be caused in several ways, such as varying the wiggler amplitude and inducing sidebands. Based on a Hamiltonian model with a set of self-consistent differential equations, it is shown in this paper that the electron- beam normalized plasma frequency functions not only couple the electron motion with the FEL wave, which results in the evolution of the FEL wave field and a possible power saturation at a large beam current, but also cause the irregularity of the electron phase-space orbits when the normalized plasma frequency has a sufficiently large value, even if the initial energy of the electron is equal to the synchronous energy or the FEL wave does not reach power saturation.展开更多

文摘In this study, a new parameter, S phase cell percentage (S fraction) normalized BrdU (SFN-BrdU) incorporation rate, was introduced to detect $ arrest. The results showed a positive linear correlation between the BrdU incorporation rate and the S fraction in unperturbed 16HBE cells. Theoretical analysis indicated that only S arrest could result in a decrease in the SFN-BrdU incorporation rate. Additionally, the decrease in SFN-BrdU incorporation rate and the activation of DNA damage checkpoints further demonstrated that S arrest was induced by diethyl sulfate treatment of 16HBE cells. In conclusion, $FN-BrdU incorporation rate can be used to detecting S arrest.
