Advances in Climate Change Research 2018年第2期9卷 120-129页

The long-term goal of the 2015 Paris Agreement is to limit global warming to well below 2 ℃above pre-industrial levels and to pursue efforts to limit it to 1.5 ℃. However, for climate mitigation and adaption efforts, further studies are still needed to understand the regional consequences between the two global warming limits. Here we provide an assessment of changes in temperature extremes over China （relative to 1986-2005） at 1.5 ℃ and 2 ℃ warming levels （relative to 1861-1900） by using the 5th phase of the Coupled Model Intercomparison Project （CMIP5） models under three RCP scenarios （RCP2.6, RCP4.5, RCP8.5）. Results show that the increases in mean temperature and temperature extremes over China are greater than that in global mean temperature. With respect to 1986-2005, the temperature of hottest day （TXx） and coldest night （TNn） are projected to increase about 1/1.6 ℃ and 1.1/1.8 ℃, whereas warm days （TX90p） and warm spell duration （WSDI） will increase about 7.5/13.8% and 15/30 d for the 1.5/2 ℃ global warming target, respectively. Under an additional 0.5 ℃ global warming, the projected increases of temperature in warmest day/night and coldest day/night are both more than 0.5 ℃ across almost the whole China. In Northwest China, Northeast China and the Tibetan Plateau, the projected changes are particularly sensitive to the additional 0.5 ℃ global warming, for example, multi-model mean increase in coldest day （TXn） and coldest night （TNn） will be about 2 times higher than a change of 0.5 ℃ global warming. Although the area-averaged changes in temperature extremes are very similar for different scenarios, spatial hotspot still exists, such as in Northwest China and North China, the increases in temperatures are apparently larger in RCP8.5 than that in RCP4.5.

Preparation of n-Atom GHZ State and Implementation of Quantum-State Transfer via Cavity Decay

引用

Communications in Theoretical Physics 2008年第3期49卷 655-658页

作者： chen Li-Bo DU Qian-Hua lin Gong-wei chen Zhi-Hua lin Xiu-Min School of Physics and Optoelectronics Technology Fujian Normal University Fuzhou 350007 China

We propose schemes to prepare n-atom Greenberger-Horn-Zeilinger （GHZ） state via two-sided cavities interacting with single-photon pulses, and achieve quantum state transfer （QST） from one atom to another atom. Entanglement particle pair and the control of coupling between qu bits are of no need in the QST process. Some practical quantum noises only decrease the success probabilities of the schemes but have no influence on the fidelity of prepared state. In addition, the success probabilities of our schemes are close to unity in the ideal case.

Fecal calprotectin correlated with endoscopic remission for Asian inflammatory bowel disease patients

World Journal of Gastroenterology 2015年第48期21卷 13566-13573页

AIM: To evaluate the correlation between fecal calprotectin(f C), C-reactive protein(CRP), and endoscopic disease score in Asian inflammatory bowel disease(IBD) ***: Stool samples were collected and assessed for calprotectin levels by Quantum Blue Calprotectin High Range Rapid test. Crohn's disease endoscopic index of severity(CDEIS) and ulcerative colitis endoscopic index of severity(UCEIS) were used for endoscopic lesion scoring. RESULTS: A total of 88 IBD patients [36 patients with Crohn's disease(CD) and 52 with ulcerative colitis(UC)] were enrolled. For CD patients, f C correlated with CDEIS(r = 0.465, P = 0.005) and CRP(r = 0.528, P = 0.001). f C levels in UC patients correlated with UCEIS(r = 0.696, P < 0.0001) and CRP(r = 0.529, P = 0.0005). Calprotectin could predict endoscopic remission(CDEIS < 6) with 50% sensitivity and 100% specificity(AUC: 0.74) in CD patients when using 918 μg/g as the cutoff. When using 191 μg/g as the cut-off in UC patients, calprotectin could be used for predicting endoscopic remission(UCEIS < 3) with 88% sensitivity and 75% specificity(AUC: 0.87). CONCLUSION: f C correlated with both CDEIS and UCEIS. f C could be used as a predictor of endoscopic remission for Asian IBD patients.

Journal of Materials Science & Technology 1997年第6期13卷 518-520页

作者： Zhaojun lin Zhanguo WANG wei chen and Lanying lin(Lab. of Sendconductor Materials Science, Institute of Semiconductors, Chinese Academy of Sciences,Beijing 100083, China) Lab. of Semiconductor Materials Science Institute of Semiconductors Chinese Academy of Sciences Beijing 100083 China

Samples have been prepared at different temperatures by loading I2 molecules into the cages of zeolite 5A, and the measurements of the absorption spectra have been carried out for the prepared samples. It is shown that I2 molecular clusters are formed in the cages of zeolite 5A,and it is also found that moIecuIar clusters which are bonded with intermoIecuIar forces have an important feature, namely, the intermolecular distance in molecular clusters can be changed on different preparing conditions and the blue shift of absorption edges can not be as the criterion of forming molecular clusters.
