Disaster clusters refer to major disasters that cluster in space and time without any linkage, resulting in large direct damage and economic ripple effects(EREs).However, the cumulative EREs caused by a disaster cluster may not be equal to the summation EREs of the individual disasters within a cluster. We constructed a global economic ripple input-output model suitable for the analysis of disaster clusters and demonstrated the extent of this difference with the example of two typical catastrophes that occurred in 2011(the Great East Japan Earthquake and the Great Thailand Flood), within an interval of only 136 days. The results indicate that:(1) The EREs suffered by 11 of the 35countries affected(30%) are “1 + 1 > 2”, and “1 + 1 < 2”for 24 of the 35 countries affected(70%). This indicates that there is a signifi cant difference between the cumulative and the summation losses. The difference is related to factors such as trade distance, economic influence of disasteraffected sectors, and trade ties;(2) The EREs are more than two times the direct loss and have an industrial dependence, mostly aggregated in key sectors with strong industrial influence and fast trade times in the industrial chain;and(3) Additional EREs due to the extension of the recovery period will be aggregated in countries with close trade ties to the disaster-affected country, further magnifying the difference.

Fizzy-related protein homolog 1 (FZR1) mainly functions as a specific activator of the anaphase-promotingcomplex/cyclosome (APC/C) in the cell cycle and controls the G0 and G1 phases of the cell cycle. We highlightrecent work that has studied the role of FZR1 in tumorigenesis, growth, differentiation, and genome stability throughcell-cycle control. We summarize the current state of knowledge regarding FZR1 structure, function, and the distinctways of APC/C dysregulation in solid tumors and hematologic malignancies. We also discuss novel approaches fortargeting the FZR1 as a cancer therapy and research area for future work.

通过仿真模拟脉冲激光对半导体器件光生载流子的影响,重点研究纵向NPN三极管(VNPN)的激光辐照效应。光照强度较小时,只有集电结反偏,而发射结处的光生电动势不足以抵消发射结的内建电势,发射结尚未开启,器件工作在以集电结为主的二极管模式;光照强度增加时,发射结逐渐开启,器件工作在三极管模式;光照强度进一步增大,由于外部限流电阻的作用,集电极电流达到饱和,器件工作在以发射结为主的二极管模式。因此,随着光照强度的增加,VNPN器件的激光辐射效应经历三个阶段,其响应曲线呈非线性变化。改变VNPN的尺寸和脉冲激光的参数,会影响器件进入三极管模式的临界点,改变非线性响应的触发光照强度,体现了器件对激光辐照效应的敏感性。

Exploiting Geo-Social Correlations to Improve Pairwise Ranking for Point-of-Interest Recommendation

引用

China Communications 2018年第7期15卷 180-201页

作者： Rong Gao Jing Li Bo Du Xuefei Li Jun Chang chengfang Song Donghua liu School of Computer Science Wuhan University

Recently, as location-based social network(LBSN) rapidly grow, point-of-interest(POI) recommendation has become an important way to help people locate interesting places. Nowadays, there have been deep studies conducted on the geographical and social influence in the point-of-interest recommendation model based on the rating prediction. The fact is, however, relying solely on the rating fails to reflect the user's preferences very accurately, because the users are most concerned with the list of ranked point-of-interests(POIs) on the actual output of recommender systems. In this paper, we propose a co-pairwise ranking model called Geo-Social Bayesian Personalized Ranking model(GSBPR), which is based on the pairwise ranking with the exploiting geo-social correlations by incorporating the method of ranking learning into the process of POI recommendation. In this model, we develop a novel BPR pairwise ranking assumption by injecting users' geo-social preference. Based on this assumption, the POI recommendation model is reformulated by a three-level joint pairwise ranking model. And the experimental results based on real datasets show that the proposed method in this paper enjoys better recommendation performance compared to other state-of-the-art POI recommendation models.

Climate transformation to warm-humid and its effect on river runoff in the source region of the Yellow River

引用

Research in Cold and Arid Regions 2014年第3期6卷 257-265页

作者： YongChao Lan HuiJun Jin chengfang La Jun Wen Jie Song JinPeng liu Cold and Arid Regions Environmental and Engineering Research Institute Chinese Academy of Sciences Institute of the Yellow River Source Yellow River Conservancy Committee

The change characteristics and trends of the regional climate in the source region of the Yellow River, and the response of runoff to climate change, are analyzed based on observational data of air temperature, precipitation, and runoff at 10 main hydrological and weather stations in the region. Our results show that a strong signal of climate shift from warm-dry to warm-humid in the western parts of northwestern China （Xinjiang） and the western Hexi Corridor of Gansu Province occurred in the late 1980s, and a same signal of climate change occurred in the mid-2000s in the source region of the Yellow River located in the eastern part of northwestern China. This climate changeover has led to a rapid increase in rainfall and stream runoff in the latter region. In most of the years since 2004 the average annual precipitation in the source region of the Yellow River has been greater than the long-term average annual value, and after 2007 the runoff measured at all of the hydrologic sections on the main channel of the Yellow River in the source region has also consistently exceeded the long-term average annual because of rainfall increase. It is difficult to determine the prospects of future climate change until additional observations and research are conducted on the rate and temporal and spatial extents of climate change in the region. Nevertheless, we predict that the climate shift from warm-dry to warm-humid in the source region of the Yellow River is very likely to be in the decadal time scale, which means a warming and rainy climate in the source region of the Yellow River will continue in the coming decades.
