We, Raf Guns and Yuxian Liu, and Dilruba Mahbuba, your students in different countries, wish you a happy birthday. and we submit our special presents on the occasion of your birthday: though our work is not perfect, we had made great efforts to show you that we are growing under your promotion. We all are profoundly grateful to you for what you have done for us.
On the 14th of August 2009, our promoter Ronald Rousseau turns 60 years old. For a long time he has been motivating us to devote ourselves to academic research, encouraging every little progress in our research. We know that he has always cherished the hope that we can work together as a real team. This is not obvious because of geographic distances. Moreover, as was shown by Jackson & Rogers (2007), the node with a higher degree tends to have a lower clustering coefficient, since the nodes in its neighbourhood prefer to link to it rather than each other. Indeed, although Ronald has always encouraged us to communicate with each other, we tend to ask him to act as a bridge. For the occasion of his 60th birthday, we have tried to overcome the fact that we are living and working in different continents, different time zones and different conditions. As president of the ISSI and a major facilitator of international collaboration himself, Ronald is – we think – certainly interested in how the researchers from different countries in our field are connected and bridging between different groups. Therefore, we have chosen the topic to do further investigation.
Excellent work: I like it very much; with some really new results. I am proud of you! What are your plans concerning this article?......
那天我把我们师姐弟合作期间来往信件整理了一下,不包括附件,从Word中的文件有50多页!
Dear Raf and Ruba:
As my box is full, I have to delete some emails. And I treasure our experience so much that I can not delete it, so I made an archive.
Anyway, we made it! As Ronald are proud of us, we can be also proud of our works: discussing a topic, exploring the unknown, overcome difficulties, correct our own mistake, try our best to find the rules, complement each other, understanding each other! Moreover, we also deal with many other things, Raf had taken part in the ISSI conference, Ruba changed her work, I also had to transfer ownership of an apartment from older owner to my own. In such short time, we overcome all difficulties and succeed in last minute! we got so much support from each other!
As Raf had said that: let's see this small research project for Ronald's birthday as a starting point rather than an end.we really have reasons to collaborate more!
I would like join Raf and say: thank for your support and your work. Thank for raf the whole days work in the 13^th of August, thank for Ruba's great effort to type Bangla font in the card,thank for your tolerance on my poor English¡¡
Friendly greetings Yuxian
Dear Yuxian and Ruba,
I can only agree with everything Yuxian has written. Although we were also occupied by many other things, we have managed to create a nice birthday present. And it really was teamwork, so thank you both!
Ronald raises some interesting questions. I cannot answer them all right awxay, but I will certainly come back to them. ......
Friendly greetings, Raf
Dear Raf and Yuxian:
I agree with Yuxian and Raf. We become more closer than before with this work. I learn a lot from both of you to mange all difficults. My best wishes to both of you and our beloved Professor.
