Metabolic Origin, Role and Fate of the Denaturant Guanidine. [PDF]
Microb BiotechnolThe origin of metabolic guanidine is largely a mystery. We suggest it is created when guanine‐containing nucleotides are oxidised by molecular oxygen instead of being broken down into urea as purines normally would. Guanidine may act as a signal to help cells control the level of reactive oxygen species.

Maxwell's Demon Walks into Wall Street: Stochastic Thermodynamics Meets Expected Utility Theory. [PDF]
Physical Review Letters, 2023 The interplay between thermodynamics and information theory has a long history, but its quantitative manifestations are still being explored. We import tools from expected utility theory from economics into stochastic thermodynamics.

Chemically Fueled Active Transport. [PDF]
Angew Chem Int Ed EnglWe report a synthetic system that uses chemical potential differences similar to biological systems to transport small molecules across a hydrophobic barrier against a concentration gradient. Instead of a complex pumping machinery, transport happens through the transient activation of transporter molecules.

Designing autonomous Maxwell's demon via stochastic resetting
Physical Review Research, 2023 Autonomous Maxwell's demon is a new type of information engine proposed by Mandal and Jarzynski [Proc. Natl. Acad. Sci. USA 109, 11641 (2012)0027-842410.1073/pnas.1204263109], which can produce work by exploiting an information tape.

Quantum Maxwell's demon assisted by non-Markovian effects. [PDF]
Physical Review E, 2021 Maxwell's demon is the quintessential example of information control, which is necessary for designing quantum devices. In thermodynamics, the demon is an intelligent being who utilizes the entropic nature of information to sort excitations between ...

The European Physical Journal Plus, 2023 RNA polymerase (RNAP) catalyzes RNA synthesis from template DNA via translocation on the DNA. The experimental value of the free energy change required for RNAP translocation exhibits an unexplainable discrepancy.

Unravelling The Threads of Enigma: Entropy, Maxwell's Demon, and Communication in 'The Crying of Lot 49 [PDF]
International Journal of Practical and Pedagogical Issues in English EducationThomas Pynchon is a great postmodernist writer whose The Crying of Lot 49 mixes postmodern elements and modern physics in an ironic way. In The Crying of Lot 49, the concepts of entropy and Maxwell's demon play a significant role in understanding the ...

Nonequilibrium phase transitions in feedback-controlled three-dimensional particle dynamics
Physical Review Research, 2023 We consider point particles moving inside spherical urns connected by cylindrical channels whose axes both lie along the horizontal direction. The microscopic dynamics differ from that of standard 3D billiards because of a kind of Maxwell's demon that ...

A Collision Between Dynamics and Thermodynamics
Entropy, 2004 : Philosophers of science have found the literature surrounding Maxwell's demon deeply problematic. This paper explains why, summarizing various philosophical complaints and adding to them.
