Introduction to Systems Biology
How does the cell know when to produce a protein? Why does it produce this protein? How does it produce this protein so accurately, in transcription, timing, and concentration? It is amazing that the cell functions as precisely as it needs to in response to various stimuli. What is more amazing is that the cell's actions are a result of stochastic processes.
Question: Is the local energy dictating dislocation emission constant for single crystal?
Hi everyone, in my size dependence study, I find the local energy dictating dislocation emission is almost constant for varied sized samples, in given directions of single crystal. I don't know this is an interesing finding, or just a common sense. Will you give me some suggestion, Thank you!

Power of iMechanica during job hunting
In July 2007, my friend of a consulting company contacted me for recruiting a computational mechanics engineer. I told him that all my graduate students found jobs, and there are not many mechanics students in our small department. So, I posted his ad at iMechanica. Only after one week, he asked me to withdraw this ad! Why?
Because many high-qualified applicants contacted him in one week and, he’d give the offer right away. I believe this example is an index of active user groups of iMechanica.
iMechanica Poster
I created this one page poster for publicizing iMechanica, primarily in schools among students, where I think a lot of students are unaware of iMechanica. I hope I am not infringing on any copyright rules or negatively impacting iMechanica's image and sensitivities. Would it be okay to print this out and post it on notice boards in school? Also, please let me know if I can improve on the design or add/remove any components. I will resubmit the final version as a pdf for student volunteers to print (if it is acceptable).
Thanks for your time,

Mechanics in the news
Since I am an alum of the University of Minnesota, when I was a PhD student I lived only a few blocks from the site of yesterday's catastrophic bridge collapse in Minneapolis. The statics analysis of a truss is almost the first thing learned by every undergraduate engineering student, and appears to be relevant here. It is interesting to see words like "fatigue crack" and "vibrations" in the news . In light o
Sci & Engng Publication Output and the Research &Publication Environment in the US: NSF Reports
Within the last two weeks the US National Science Foundation (NSF) published not one but two studies on (a) the attitudes of scientists and engineers to the changing world of publication, and (b) the relative global productibity of US science & engineering as measured by journal publication.
These are not dense 500 page reports, but short, readable (10-15 min.). I think iMechanica readers will find them relevant and interesting:
CALLING ALL STUDENTS! (and everyone else)
Recently, Prof. Suo and several of us students have been discussing the possibility of increasing student presence and activity on iMechanica . With this in mind, two of us: Mahdi Kazemzadeh and I, have identified three important issues we would like to get your thoughts on. Please comment and let us know what you think, even if you are not a student. Also, if you wish to add any more issues you think we should look at, please post your thoughts in this regard as well.
