同步現象的研究

In our daily life, objects and the contacts between objects they will have mutually affect each other, some initially chaotic systems after a sufficient amount of time will mutually correct each other, and finally achieve synchronization (example: the speed of bird and fish migration, market prices, infantry…), although some are unable to achieve this. We will illustrate and explain the synchronization system, its process and discover the conditions for synchronization. Using linking concepts, we will integrate the coupled map lattices with global coupling and coupled map lattices with intermediate-range models into a synchronization mode in order to simulate a synchronization system. We first used a small system of n≦50 to obtain results that will demonstrate the linking concepts: 1. The more chaotic a system, a longer period of time is required for synchronization. 2. An increase in the number of individual objects requires an increase in the range of concepts and the amount of time in order to achieve an in depth synchronization. 3. Initial concept values which randomly effect synchronization critical point conditions are not obvious in a mathematically incorrect graph. In a closer look, when we increased the synchronization to n≦400 and the number of times to t-->100,000 we discovered:1. Using the function G(x) we hoped the results from the graph after apply the function and correction able to overlap and test with “Scaling and Universality in Transition to Synchronous Chaos with Local-Global Interactions”, but the part which overlapped the measurements was not identical: 2. We can use the significance of the critical point and the Interactive Process to find the approximate value of the critical value up to 4 digits following the decimal point. 3. We can also use the approximate value to find out the range for the simultaneous conditions and the various points on the system itself, as well as obtain a negative correlation between them, and then it can be similarly expressed with using a curve. A computer can calculate values with this kind of enumerating method, even without any special resolution capabilities to quickly obtain large amounts of approximate values of simultaneous conditions, this is especially true when calculating unfamiliar systems. 日常生活中,物件與物件的接觸,彼此會互相影響,有些原本雜亂的系統再經過充裕時間的互相修正後,最後竟能達成同步(例如:鳥群、魚群遷徙的速度、市場價格、行軍步伐…),有些則不能。因此,我們試著利用描述同步系統的模型,觀察系統同步的過程,並且找出同步的條件。由連結的觀點,我們將Coupled map lattices with global coupling 和Coupled map lattices with intermediate-range 模型的優點整合成Synchronization mode 去模擬同步系統。我們先用小系統(n≦50)得到能印證連結觀點的結果:(一)、系統越雜亂,就需要稍長的時間同步;(二)、個體數越多時,各點需要更大範圍的點數去影響於每單位時間內以及更深的影響才能同步;(三)、起始值隨機影響同步臨界條件並不明顯,在誤差範圍內。更進一步,我們將系統推向n≦400 點,t→100,000 次,我們發現:(一)、在”G(x)”我們希望能將圖形經過函數修正之後能疊和,驗證”Scaling and Universality In Transition to Synchronous Chaos with Local-Global Interactions ”中的結果,但只有部分疊和,尺度不相同;(二)、可以直接利用臨界點的意義用十分逼近法求出臨界值的近似值到小數後四位;(三)、我們用近似值也能發現同步條件與系統各點本身可跳躍的數值範圍是負相關,可用曲線去近似。這種窮舉方式,交由電腦運算,不需要特別的解析能力就能夠快速且大量求得同步條件的近似值,尤其在運算不熟悉的系統時。

The Use of Simulated Annealing in Predicting Solar Flare Activity

A program based on the simulated annealing (SA) algorithm was developed to allow for a longer-term prediction of the occurrence of solar flares, thus reducing the risks they may pose to astronauts, satellites, and ultimately the planet Earth. Sunspot data such as the solar cycle, the appearance of sunspots, the sun's magnetic field, the occurrence of solar flares and other factors that concern the sun were considered in the development of the algorithm. The program, coded in C++, included providing for an initial random state that pertained to the sun's state at a specified time. A neighborhood function was designed based on how sunspots are formed and how they disappear, and the probability function was designed using previous solar cycles to show relationships between the number of sunspots and the time it takes for the sun to reach solar maxima. Finally, the cooling function was designed as a representation of the time. Recorded sunspot counts obtained from the US National Geophysical Data Center (NGDC) during the solar cycle 22 from 1986 to 1996 was used as test data. The output was compared to the actual recorded solar events or the period. The program was found to be 66.7% accurate in predicting solar flares when compared on a smoothed trendline, while it exhibited a 50.5% accuracy when comparing day-to-day data. Since solar flare acitivty is predicted in terms of the trend of activity and intensity, improving daily data accuracy is superfluous. Smoothed trendline prediction accuracy may however be improved by altering the importance of each factor in predicting solar flare activity and by devising a different sunspot classification scheme for intensity and activity.

Why Spiderman cannot do without his silk?-The effects of dragline silk on jumping performance of jumping spider (Hasarius adansonl)

由於蜘蛛絲複雜的分子結構及產生過程,長久以來一直被視為一個特殊的生物材料(高延展性,高韌性,和高強度),此外,前人研究指出蜘蛛能自己調控絲的性質,並受到環境的影響。然而,大多數的研究多以結網性蜘蛛為主,只有極少數研究著重在探討非結網性蜘蛛,如:跳蛛。本研究中,以安德遜蠅虎為材料,分析跳蛛的跳躍行為,以及探討曳絲在跳躍過程時所造成的影響。我們初步的研究結果顯示: (一)曳絲在跳蛛跳躍過程中,對於安全降落扮演重要的角色,及(二)跳蛛會藉由改變身體的角度來維持身體的平衡。在跳躍過程中,蜘蛛的跳躍速度會因空氣阻力而減少,但是蜘蛛絲的彈性恢恢復力(根據虎克定律)會讓跳蛛跳躍速度更顯著的減少,並藉著身體的轉動與曳絲的作用達到身體平衡。對於一個非結網性蜘蛛是另外一個不可或缺的輔助工具。相對於其他跳躍動物,有絲的跳蛛具備另一項能減緩降落速度的工具以增加降落的安全性。

Eye gone V.S.eyeless決定果蠅複眼發育基因之協同作用與未知調控基因之尋覓

In this study, we try to know how ectopic eye genes: eyeless(ey), eye gone(eyg), twin of eyeless(toy), twin of eye gone(toe) act cooperatively, and look for some unknown genes which affect the function of eyg. First, through human trans gene screening, we find two human genes change the phenotype of ey>eyg into dorsal out-growth when they co-express with eyg (ey>eyg+X). It means the two genes may relate to cell proliferation. Second, by sequencing the insert genes of mutant fly which was found by EP screening, the result shows the site of the insertion is the same as effete (eff) gene. eff translated wrong proteins which differ from functional ubiquitin-conjugating enzyme may be the major cause of the mutant eye . 本研究係探討果蠅複眼異位基因eyeless(ey)、eye gone(eyg)、twin of eyeless(toy)、 twin of eye gone(toe)間的協同作用,並尋找與eyg 有交互作用的基因、突變株。藉由人類基因轉殖篩選,找到兩株人類基因轉殖株,當其與eyg 共同表現時(ey>eyg+X),會改變ey>eyg 的複眼性狀,造成dorsal out-growth,顯示這兩個基因可能與細胞增生有關,此外,藉由EP screening 複眼發生突變的果蠅之UAS 下游基因經比對後,位置與effete(eff)部分契合,推測複眼發生突變的原因是eff 的功能發生異常,致使細胞內蛋白質代謝失常所致。

竹筍老化之謎

本研究是在探討收割後的綠竹筍(Bambusa oldhamii, green bamboo)的老化(aging)現象。一般人說的竹筍老了,通常是指竹筍的質地變硬,口感變差,此即是竹筍硬化的現象,而硬化的主因可能是竹筍受到逆境 (stress) 的刺激後,影響了基因表現的形態,導致纖維素和木質素的增加。竹筍採收後以不同方式處理,觀察切面的變化後發現,以0.2 M蔗糖水浸泡48小時後的竹筍,其切面比浸泡於水中或置於空氣中的竹筍切面較白,筍尖較綠且沒有枯萎的情況。不管是浸泡糖水、水或置於空氣中,都無法防止竹筍的硬化,但浸水和糖水可延緩竹筍硬化的情形,可見要防止竹筍老化,基本上要從抑制合成纖維素與木質素的酵素來著手。抽取竹筍切面處組織中的DNA並以DNA電泳分析之後發現,竹筍的DNA有被降解成小片段的現象,其大小差不多是180 bp的倍數,可見竹筍遇到逆境時也可能會有類似PCD (programmed cell death, 細胞程序性死亡) 的現象。抽取不同處理竹筍的蛋白質進行2D電泳,比較電泳結果發現,三種處理的竹筍的共同點在於減少的蛋白質幾乎都分布在等電點較低的部分。增加的蛋白質大多數分布在等電點較高的區域,這些增加的蛋白質可能和竹筍老現象與PCD有關。本研究還有兩個方向可以繼續延伸研究,第一個是將2D電泳上有明顯差異的蛋白質色點挖出,進行蛋白質定序,再從資料庫中比對,推測可能是何種蛋白質。第二個是研究抑制竹筍合成纖維素和木質素的?的方法,保持竹筍的口感,使竹筍能成為一種能外銷的食品。 The purpose of this study is to investigate and analyze the aging of the harvested green bamboo shoots. The research focused on how to prevent the aging of bamboo shoots and why green bamboo shoots become aging. The term “aging” means that the taste of bamboo shoots becomes hardness post harvest. At first, we tried to find out an anti-aging method, which is not only to keep the green bamboo shoots fresh, but also delicious. The method was to soak bamboo shoots in 0.2 M sucrose, in the water or without any treatment. After 48 hours, the cutting surfaces of bamboo shoots treated with sucrose were whiter, and their outer sheaths were greener than those of shoots soaked in the water or without treatment. The results showed that none of them can stop hardness. But the aging of sucrose- or water-treated shoots was retarded. The results suggest that inhibition of the enzyme activities involving cellulose and lignin synthesis may be required to prevent the aging of bamboo shoot post harvest. To get insight into the reason why bamboo shoots become hardness, the differences of protein patterns and DNA patterns between aging and fresh green bamboo shoots were analyzed and compared. The DNA from the bamboo tissues near cutting surface was isolated and analyzed by agarose gel electrophoresis. The results showed that DNA from shoots was partially degraded. The fragments appear as a ladder of DNA with sizes in multiples of approximately 180 bp. The presence of the olignucleosome-size DNA fragments suggest that the cells may undergo programmed cell death (PCD). The degradation of DNA was not observed in shoots treated with sucrose. By comparing the results of 2-D gel electrophoresis, it was found that some proteins with low pI values decreased or disappeared post harvest, while proteins with increased levels were detected in the high pI area. These changes in these proteins may result in the aging of the bamboo shoots. Prevention of the aging of green bamboo shoots is not easy. However, I found out from this study that soaking the bamboo shoots in the 0.2 M sucrose was a possible way to preserve them. The cutting surface of sucrose-treated shoots remained white, and the sheaths of the shoots was greener than those treated with other methods. Moreover, the degradation of DNA was not observed. However, it still cannot completely stop the aging of bamboo shoots. Reducing the enzyme activities involving cellulose and lignin synthesis may be a direct way to prevent the aging of bamboo shoots. It seems like there are many things to discover in the future.
