麥基爾大學台灣研究生同學會

Dear Visitors,

Due to the interactive nature and the easy maintainability of a Facebook group, we've migrated most of our online activities to Facebook. I urge you to visit our group site at:

各位會員

有鑑於大家在畢業後都得找工作，經過Vicky建議後，我在這邊開一個置頂的版面讓大家提供相關徵才訊息，不管是台灣加拿大或是全世界的徵才訊息，都請不吝貼到這篇的回文中喔!

歡迎光臨麥基爾大學台灣研究生會(McGill Taiwanese Graduate Student Association，簡稱MTGSA）的部落格，成立的目的是希望能提供新生一些有用的資訊，也能作為舊生或校友間交流的平台。
(草創初期，持續更新中，希望各位新舊生可以幫忙提供資訊，可以加速完工。會開闢一堆主題，但是裡面可能沒什麼內容，如果想提供資訊，可以寄信給我，或是在留言版/相關文章直接留言(在「迴響」點一下後，點頁面下方的「有話想說嗎？」的圖片），我會盡快把所得到的東西整合更新）^_^

The 2011/2012 school year is about to come to an end.

While we welcome the new students who made an wise decision to embark an adventure at McGill University, we look back to an eventful year full of fun and academic rigor.

With the new school year right around the corner, it is time for us to elect a new president to take us through another dreadful year of graduate studies.

The date, time, place, and presidential candidate for the Presidential Election banquet have been decided and are as follows:

To all,

Hi, this is Yu-Ting.

There is going to be a BBQ event on Saturday, September 24th!

Information regarding the event has been sent via email

各位會員好

昨天的聚餐感謝大家的支持，David Yeh已經是下一屆的會長了，他對明年一整年度有很多計畫，請大家多多支持。我在接下來這一周會把所有資料交接給他。

各位會員好

各位會員好

又到了一年一度該交接的時候了，交接最重要的事情就是選會長，原則上我們會挑一家餐廳進行，因此想要詢問各位的時間，就請各位回覆在這篇文章之後喔!

大家好

高陞學長的同事想要轉租公寓，在concordia附近，有興趣的可以直接聯絡。

大家好:

很快又是七月中了,8月新生們即將陸續到達蒙特婁,今年感覺上又有不少新生會加入McGill.為了能較為精確地掌握新生的人數和預定抵達蒙特婁的時間,以便幫助各位新生適應新環境,請各位新生做個簡單自我介紹(姓名 科系 聯絡方式 其他)和跟我們說你預定抵達蒙特婁的時間~請用"迴響"的方式回應於本文.

又是一年一度新生入學的時刻了～我們即將有幾位生力軍加入我們的行列，身為新生，一定有很多問題和困惑吧！找不到人問嗎？沒關係！我們特地開放本文「新生專區」，歡迎各位新生，若想作自我介紹或是有任何的問題，可以用「回應」本文的方式來問（按本文下方的「迴響」兩字）。一來大家可以直接就你的問題，有效率且迅速地回答，二來若之前有人有問過剛好你也想問的問題，你也可以馬上獲得解答。

最後提醒一下，大家都很熱心也很願意回答各位的問題，不過建議問問題時，能把問題講得越清楚越好，不然有時大家可能會不知如何回答，或是答非所問唷！

大家好
副會長David他要徵求一些實驗室的受試者，年齡是十八歲到三十歲，詳情如下，有興趣者請直接和他聯絡，謝謝!

各位會員好

這次第一次試辦的網路研討會，感謝大家的響應和支持，目前總共有六篇文章送達，請大家前來部落格深入了解同學會的大家在忙些什麼研究。

In 2009, heart disease and stroke were two of the three leading causes of death in Canada. Therefore, finding ways in which we can effectively prevent cardiovascular emergencies remains extremely important. Previous research has shown that the frequency and severity of cardiovascular emergencies, including heart attacks, are highest in the morning hours and during the last phase of sleep. This result is not surprising as one of the most important factors in the regulation of human physiology, including the cardiovascular system, is the circadian pacemaker. To understand why the morning hours and the last phase of sleep are the most dangerous periods for having cardiovascular emergencies, we will be examining the relationships between the function of the heart, the circadian clock, posture, and sleep. Sixteen healthy men and women, aged 18 to 30, will be enrolled from the community for a six day study. During the experimental period, participants will be taking multiple naps at different times of day, while having their heart activity and blood pressure monitored continuously. Participants will also perform postural changes upon awakening from the multiple naps to simulate the action of getting out of bed after normal sleep episodes. This procedure will allow us to examine how heart activity changes in relationship to sleep and posture at different times of day. Results from the current study will help us to better understand the role of disrupted sleep on the increased risk of developing high blood pressure and cardiac problems observed in shift workers, as well as the overall increased risk of cardiovascular events in the morning for the general population.

The Arctic is a very harsh environment where living things, such as plants, animals and microorganisms, cannot grow and survive easily with low temperatures, low water activity, low nutrition, high radiation exposure, and high salt concentration. Although the Arctic is not a suitable environment for living things, microorganisms can still be found in several ecosystems, such as permafrost, ice wedges, glaciers, ice shelves, cryonite holes, and subglacier lakes, etc., in the Arctic area with their own specificity. How diverse the microbial composition in those ecosystems can be is still an interesting issue because people are not acquainted with those extreme environments.
My study focuses on the microbial diversity in the Arctic. The sampling site, Lost Hammer Spring located in the Canadian High Arctic, Axel Heiberg Island, is a unique, unfrozen, highly saline, and perennial spring with gas bubbling with rich methane. Currently, I am working on the metagenomic and metatranscriptomic study of the sediments from the source of the spring and its channel. Furthermore, from the sediments of the outflow channels, I have already completed 16S rRNA clone libraries of bacteria and archaea for realizing the bacterial and archaeal composition in the channel sediment. So far, several interesting phylotypes, such as methanogenic, methylotrophic, and Thaumarchaeota-like microorganisms, have been found in the clone libraries. As well some representatives of bacteria have been cultured in relatively high concentration of NaCl under subzero temperatures. Some of the representatives can even survive and grow with relatively high concentrations of perchlorate, which is a highly hazardous salt for most microorganisms. This research implies the relationship between the microorganisms inhabiting in such extreme environment and the geochemical features. Furthermore, the results of the research can also be applied to the research of astrobiology due to the analogous features of the sampling site compared with the extraterrestrial bodies, such as Mars, Europa, or Encaladus.

The Finite Element Method (FEM) is a mesh-based numerical method, which is conventionally used in engineering computational mechanics. However, the FEM has limited application in many complex problems such as free surface problems and large deformations. In order to deal with the problem of limited application, the Smoothed Particle Hydrodynamics (SPH) Method was developed in 1977. This method is mesh free by replacing the nodes used in FEM by particles. Since there is no connectivity between particles, the SPH Method avoids element distortion and is applicable to solving problems of high velocity impact and penetration behavior into solid materials.
As with other mechanics calculations, the SPH Method is governed by momentum and energy conservation laws, which are expressed as interparticle forces. Each particle within the SPH numerical calculation has a fixed mass and follows the fluid motion, which is evaluated by the approximation function. Furthermore, the smoothing length is computed by the divergence function and the distance between each couple of particles is checked to see that it is smaller than twice the smoothing length. By determining the smoothing length as the influence neighbor sphere radius, enough particles are kept in the neighbor sphere to validate continuum variables and avoid problems in material compression and expansion. After that, keeping the same number of particles is equal to keeping the same mass of particles in the neighbor sphere. The minimum and maximum values required for the smoothing length are 0.2 and 2, respectively, times the initial smoothing length, while the default value is 1.2 times the initial smoothing length.
