Entropy and entropy production in some applications [PDF]
Physica A: Statistical Mechanics and its Applications, 2014 By using entropy and entropy production, we calculate the steady flux of some phenomena. The method we use is a competition method, $S_S/τ+σ={\it maximum}$, where $S_S$ is system entropy, $σ$ is entropy production and $τ$ is microscopic interaction time. System entropy is calculated from the equilibrium state by studying the flux fluctuations.

‘Guide and Prejudice’— How Argonautes recognize targets across domains of life
FEBS Letters, EarlyView.Argonaute proteins use short nucleic‐acid guides to locate and regulate specific targets across all domains of life. Despite striking diversity—from human gene silencing to bacterial immune defence—all Argonautes share a conserved three‐stage recognition logic: guide‐directed sampling, progressive target pairing with a conformational checkpoint and ...

The minimal entropy problem for 3-manifolds with zero simplicial volume [PDF]
, 2003 In this note, we consider the minimal entropy problem, namely the question of whether there exists a smooth metric of minimal (topological) entropy, for certain classes of closed 3 ...

Distinguishing intrinsic and interfacial pyroelectric effects by polarization reversal measurements
Nature CommunicationsPyroelectric devices hold promise for thermal energy harvesting and sensing. While previous studies have focused on the intrinsic pyroelectric response, they neglect the interfacial pyroelectric effect at the electrode-material interface, leading to an ...

FEBS Letters, EarlyView.How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers
FEBS Letters, EarlyView.Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

CONTINUITY OF A CLASS OF ENTROPIES AND RELATIVE ENTROPIES [PDF]
Reviews in Mathematical Physics, 2004 The present paper studies continuity of generalized entropy functions and relative entropies defined using the notion of a deformed logarithmic function. In particular, two distinct definitions of relative entropy are discussed. As an application, all considered entropies are shown to satisfy Lesche's stability condition. The entropies of Tsallis' non-
