Ant colonies self-organize to solve complex problems despite the simplicity of an individual ant＇s brain. Pavement ant Tetramorium caespitum colonies must solve the problem of defending the ter- ritory that they patrol in search of energetically rich forage. When members of 2 colonies randomly interact at the territory boundary a decision to fight occurs when： 1） there is a mismatch in nest- mate recognition cues and 2） each ant has a recent history of high interaction rates with nestmate ants. Instead of fighting, some ants will decide to recruit more workers from the nest to the fighting location, and in this way a positive feedback mediates the development of colony wide wars. In ants, the monoamines serotonin （5-HT） and octopamine （OA） modulate many behaviors associated with colony organization and in particular behaviors associated with nestmate recognition and ag- gression. In this article, we develop and explore an agent-based model that conceptualizes how in- dividual changes in brain concentrations of 5-HT and OA, paired with a simple threshold-based de- cision rule, can lead to the development of colony wide warfare. Model simulations do lead to the development of warfare with 91% of ants fighting at the end of 1 h. When conducting a sensitivity analysis, we determined that uncertainty in monoamine concentration signal decay influences the behavior of the model more than uncertainty in the decision-making rule or density. We conclude that pavement ant behavior is consistent with the detection of interaction rate through a single timed interval rather than integration of multiple interactions.

Wars as Dividing Significance of the Lines？ Rethinking the Sino-j.panese War in Twentieth Century China

引用

Frontiers of History in China 2018年第1期13卷 73-89页

作者： j. Megan greene Department of History University of Kansas Lawrence KS 66045 USA

Historical periodization frequently takes wars as turning points--as ruptures that signify the end or beginning of an era. At the same time, front lines have often been taken as boundaries that contain the activities of one side or the other. Thus, discontinuity and disj.ncture rather than continuity and fluidity have o-en been the points of emphasis among historians who have taken war events as turning points, or who have seen lines of combat as impermeable. A new focus on the Sino-j.panese War period has begun to reveal ways in which that moment served not as an interruption but as a part of longer term processes of change and development that characterized China＇s mid-twentieth century. It also permits us to gain a deeper understanding of the fluidity of human movement and socio-economic interaction that frequently boundaries and to think about similarities various Chinese spaces. The aim of this paper crossed both political and military linkages, and differences between is to consider ways in which the new generation of scholarship on the Sino-j.panese War period offers new ways of thinking about continuity, change, similarity and difference across both temporal and physical boundaries that have served as the parameters for much of the earlier scholarship on the period. To this end, the paper examines recent literature on the Sino-j.panese War period, as well as literature that crosses that period, to examine ways in which this historiography has challenged conventional periodizations and political and geographical delineations

铁反应元件 (IRE)具有的高度保守的RNA茎环结构 ,是胞质中IRE结合铁调控蛋白 (IRP)的位点。IRP与IRE的结合受细胞内铁含量的调控 ,与铁代谢有着密切的关系。许多与铁代谢有关的基因在 5′UTR或 3′UTR都存在IRE。当铁离子缺乏时 ,IRE与IRP结合 ,使核糖体的翻译进程受阻 ,抑制mRNA的翻译 ;而当铁离子浓度较高时 ,IRP就释放IRE ,促进翻译。因此 ,IRE在 5′UTR调节着翻译的起始[1] 。如果IRE位于 3′UTR ,IRE与IRP的结合可以稳定mRNA并预防其被降解。所有已知的IRE均为C1G5型 ,即环的 1号和 5号碱基位置分别是保守的C和G ;另外还存在一类体外合成的U1A5型IRE ,即环的 1号和 5号碱基位置分别是保守的U和A ,能够在体外有效地结合IRP。由于IRE与铁代谢、氧化性损伤 (oxidativestress)和衰老等过程都有密切的关系 ,因此在临床及新药研制等方面都很受重视。通过改进搜索IRE的算法 ,用计算机程序对人与鼠的mRNA非编码区(UTR)序列数据库进行全面的搜索 ,期望找出可能存在的C1G5或U1A5类型的IRE ,或包含这两种类型IRE的基因。

Proj.cted Future Wind Speed and Wind Power Density Trends over the Western US High Plains

引用

Atmospheric and Climate Sciences 2012年第1期2卷 32-40页

作者： j. Scott greene Matthew Chatelain Mark Morrissey Steve Stadler 不详

This manuscript presents the results of research on future changes in wind speed and wind power density across the western US High Plains in an area known for its high wind energy resources. Many current policies and economic analyses involving the rapidly expanding wind energy industry have assumed a constant or near constant wind resource. However, any future change in wind speeds will result in changes in the reliability of wind power as an energy resource. This paper uses current data (1970-2000) and future model output (2040-2070) to analyze decadal and seasonal changes in wind speed across the study area. In addition, estimated hub height wind power densities have been analyzed. Results show proj.ctions of a slight overall decreasing wind power in the future across the region. The greatest magnitude changes are estimated to be in the seasonal trends with the most substantial decreases occurring in winter and spring. As climate changes and warms overall, there will be shifts in the temperature gradients and the synoptic storm tracks that drive wind speeds. Thus, it is theorized that the wind speeds will be the result of an earlier transition to, and longer duration of, a calmer summertime pattern. This longer duration of a summertime pattern will lead to the decreased wind speeds and lower wind power output identified in this research. This decrease needs to be factored in for any estimates of the long-term costs and benefits of wind farms in the area.

Development of a Portable Electronic Sensor for Detection of the Kudzu Bug, <i>Megacopta cribraria</i>(Fabricius) (Hemiptera: Plataspidae)

引用

Advances in Entomology 2017年第3期5卷 75-86页

作者： Brittany D. Lampson David C. Degenhardt j.remy K. greene Ahmad Khalilian Young j. Han Department of Agricultural Sciences Clemson University Clemson SC USA Ridge View High School Columbia SC USA Department of Plant and Environmental Sciences Clemson University Clemson SC USA

The kudzu bug, Megacopta cribraria (Fabricius), recently became an invasive insect pest of soybean, Glycine max (L.) Merr. in the southeastern USA capable of reducing crop yield by as much as 60% if left untreated. To reduce these losses and minimize control costs, new methods for detecting kudzu bugs must be investigated in order to optimize control measures. One such method would be to detect volatiles released by kudzu bugs. An electronic portable device was developed to draw volatile organic compounds (VOCs) produced by kudzu bugs over carbon black-polymer composite sensors and measure the change in resistance for each sensor. Sensors made using polymers poly (bisphenol A carbonate) (p = 0.041), poly (styrene-co-allyl alcohol) (p = 0.017) and poly (vinylpyrrolidone) (p = 0.040) showed significant differences in resistance change for M. cribraria VOCs over the control. A logistic regression was 94.4% accurate based on the resistance changes from sensors made from polymers poly (4-vinylphenol), poly (styrene-co-allyl alcohol), and poly (vinylpyrrolidone) as features. These results indicate the capability of the device to detect kudzu bugs by detecting volatiles released by the insects.
