Entropy production on a single trajectory of the small system

The following PowerPoint file is from the talk which I gave in my research group recently. It is also my understanding and reading notes from a serial of papers by Prof. Udo Seifert, in which he generalized the entropy production on a single trajectory of the small system such as a molecular machine. It mainly addresses three questions:

Earthquake in West China

After I put down the phone, my heart never felt so heavy. I just called my parents in my hometown, Chengdu,  a city with 12 million people, which is just 90 kilometers away from the center of the strong earthquake at a magnitude of 7.9.  It has killed more than 10,000 people so far. The death toll is still rising hour by hour.

The story behind the proof of Fermat's Last Theorem

When I came to the institute, my collaborator Kay invited me for a dinner in the new town together with his friend Thilo and other guys. The city is wisely divided into two functioning areas, old town and new town. All the ancient buildings like King’s summer palace, women’s church and opera house are in the old town; while the restaurants, bars and other modern buildings are in the new town. Each is in harmony with its environment and cultural atmosphere.

Research experience from a physicist

Just back from Prof. Mahir Hussein's seminar. He is really one of best physicist I  have ever met. In past 30 years, he published more than 200 papers in the field of nuclear resonance, laser accelerated particles etc. There are more than 30 papers published in PRL alone. When input his name " M.Hussein" in arXiv.org, you can easily found 95 papers by him.

4 billion years evolution in 8 min.

Recently I saw an animation
named “The inner life of the cell”, which was made by Howard Hughes Medical Institute and Harvard University Biovision. It can be watched online only:

Ten commandments in systems biology

The 5th European Conference
on Complex System is holding in Dresden, Germany now. This is really
an emerging research area. The multiple para-sessions themselves show
how diverse and multi-disciplined it is. It includes:

  • Complex system method

  • Cognition

  • Networks

  • Social system

  • Biological system

Manchester biophysics meeting --- DNA nanomachines

The 2-day conference of biophysics in Manchester had just finished recently. It is really a meeting with a tight schedule and lots of new stuffs.

The meeting took place in the new building of multi-decipline biocenter in Manchester University. One interesting speech was given by Prof. Andrew J. Turberfield 

from Oxford university. Recently his group focuses on build some small molecule machines using DNA as the building block. It is just like
