] 2 5 M ar 1 99 8 Efficiency of Brownian Motors
The efficiency of different types of Brownian motors is calculated analytically and numerically. We find that motors based on flashing ratchets present a low efficiency and an unavoidable entropy production. On the other hand, a certain class of motors based on adi-abatically changing potentials, named reversible ratchets, exhibit a higher efficiency and the entropy production can be arbitraril...
متن کاملFlower show
Kew Gardens in London opened last month the first gallery in the world to open all year round dedicated to botanical illustrations. The gallery will showcase art from Kew’s unique historic collections as well as Shirley Sherwood’s contemporary collection of botanical art. The two collections, which complement each other, will allow Kew to show to the public many of its largely unseen works and ...
متن کاملOn the Bulk Velocity of Brownian Ratchets
In this paper we study the unidirectional transport effect for Brownian ratchets modeled by Fokker–Planck-type equations. In particular, we consider the adiabatic and semiadiabatic limits for tilting ratchets, generic ratchets with small diffusion, and the multi-state chemical ratchets. Having established a linear relation between the bulk transport velocity and the bi-periodic solution, and us...
متن کامل8 M ar 2 00 7 epl draft Information and maximum power in a feedback controlled Brow - nian ratchet
Closed-loop or feedback controlled ratchets are Brownian motors that operate using information about the state of the system. For these ratchets, we investigate the relationship between the maximum power output and the information used in the feedback control. We get analytical expressions for one-particle and few-particle flashing ratchets, and we find that the maximum power output has an uppe...
متن کاملEnhancing the Curation of Botanical Data Using Text Analysis Tools
Automatic text analysis tools have significant potential to improve the productivity of those who organise large collections of data. However, to be effective, they have to be both technically efficient and provide a productive interaction with the user. Geographic referencing of historical botanical data is difficult, time consuming and relies heavily on the expertise of the curators. Botanica...
