Principles of maximum entropy and maximum caliber in statistical physics
TL;DR: The variational principles called maximum entropy (MaxEnt) and maximum caliber (MaxCal) are reviewed in this paper, and the different historical justifications for the entropy $S = \ensuremath{-}\ensurem{-} √ √ p √ i √ log √ ǫ(p) √ I √ n) and its corresponding variational principle are reviewed.

The heat released during catalytic turnover enhances the diffusion of an enzyme
Clement Riedel,Ronen Gabizon,Christian A. M. Wilson,Kambiz M. Hamadani,Kambiz M. Hamadani,Konstantinos Tsekouras,Susan Marqusee,Steve Pressé,Carlos Bustamante +8 more
TL;DR: It is proposed that the heat released during catalysis generates an asymmetric pressure wave that results in a differential stress at the protein–solvent interface that transiently displaces the centre-of-mass of the enzyme (chemoacoustic effect).
Journal ArticleDOI
The ClpXP protease unfolds substrates using a constant rate of pulling but different gears.
Maya Sen,Rodrigo A. Maillard,Kristofor Nyquist,Piere Rodriguez-Aliaga,Steve Pressé,Andreas Martin,Carlos Bustamante +6 more
TL;DR: Single-molecule analyses reveal that phosphate release is the force-generating step in the ATP-hydrolysis cycle and that ClpXP translocates substrate polypeptides in bursts resulting from highly coordinated conformational changes in two to four ATPase subunits.
The heat released during catalytic turnover enhances the diffusion of an enzyme
Clement Riedel,Ronen Gabizon,Christian A. M. Wilson,Kambiz M. Hamadani,Kambiz M. Hamadani,Konstantinos Tsekouras,Susan Marqusee,Steve Pressé,Carlos Bustamante +8 more
TL;DR: In this article, the authors used single-molecule fluorescence correlation spectroscopy to show that for enzymes that catalyse chemical reactions with large reaction enthalpies, the heat released at the protein's active site during catalysis transiently displaces the protein center-of-mass, essentially giving rise to a recoil effect that propels the enzyme.
Journal ArticleDOI
Nonuniversal power law scaling in the probability distribution of scientific citations
TL;DR: A model for the distribution of scientific citations is developed and it is found that papers having few citations are cited mainly by the direct mechanism, and papers already having many citations (“classics”) are cited mostly by the indirect mechanism.
