Reversible Conservative Rational Abstract Geometrical Computation Is Turing-Universal [PDF]

open access: green, 2006
In Abstract geometrical computation for black hole computation (MCU '04, LNCS 3354), the author provides a setting based on rational numb ers, abstract geometrical computation, with super-Turing capability. In the present paper, we prove the Turing computing capability of reversible conservative abstract geometrical computation.

A Rationally Designed Reversible ‘Turn-Off’ Sensor for Glutathione [PDF]

open access: goldBiosensors, 2017
γ-Glutamyl-cysteinyl-glycine (GSH) plays a critical role in maintaining redox homeostasis in biological systems and a decrease in its cellular levels is associated with diseases. Existing fluorescence-based chemosensors for GSH acts as irreversible reaction-based probes that exhibit a maximum fluorescence (‘turn-on’) once the reaction is complete ...

A Rational Approach to Reversibility via Carnot’s Lost-Work

open access: diamondInternational Journal of Chemistry, 2019
The reversibility definition emerging from Carnot’s ‘lost-work’ notion or, equivalently, from considerations of optimal efficiency and lack of dissipation is here qualified as a rational alternative to that which based on Planck’s constant total-entropy criterion resorts to either a sequence of equilibrium states

Rational design of reversible inhibitors for trehalose 6-phosphate phosphatases

open access: greenEuropean Journal of Medicinal Chemistry, 2017
In some organisms, environmental stress triggers trehalose biosynthesis that is catalyzed collectively by trehalose 6-phosphate synthase, and trehalose 6-phosphate phosphatase (T6PP). T6PP catalyzes the hydrolysis of trehalose 6-phosphate (T6P) to trehalose and inorganic phosphate and is a promising target for the development of antibacterial ...

A combinatorial model for reversible rational maps over finite fields [PDF]

open access: greenNonlinearity, 2009
We study time-reversal symmetry in dynamical systems with finite phase space, with applications to birational maps reduced over finite fields. For a polynomial automorphism with a single family of reversing symmetries, a universal (i.e., map-independent) distribution function R(x)=1-e^{-x}(1+x) has been conjectured to exist, for the normalized cycle ...

Coloring the rationals in reverse mathematics [PDF]

open access: yesComputability, 2016
Ramsey’s theorem for pairs asserts that every 2-coloring of the pairs of integers has an infinite monochromatic subset. In this paper, we study a strengthening of Ramsey’s theorem for pairs due to Erdős and Rado, which states that every 2-coloring of the pairs of rationals has either an infinite 0-homogeneous set or a 1-homogeneous set of order type η,

Options as information: Rational reversals of evaluation and preference. [PDF]

open access: yesJournal of Experimental Psychology: General, 2014
This article develops a rational analysis of an important class of apparent preference reversals-joint-separate reversals traditionally explained by the evaluability hypothesis. The "options-as-information" model considers a hypothetical rational actor with limited knowledge about the market distribution of a stimulus attribute. The actor's evaluations

Knot reversal and rational concordance

open access: yesBulletin of the London Mathematical Society, 2022
AbstractWe give an infinite family of knots that are not rationally concordant to their reverses. More precisely, if denotes the involution of the rational knot concordance group induced by reversal and denotes the subgroup of knots fixed under in , then contains an infinite rank subgroup.

Rationally Designed Probe for Reversible Sensing of Zinc and Application in Cells [PDF]

open access: goldACS Omega, 2017
Biologically compatible fluorescent ion sensors, particularly those that are reversible, represent a key tool for answering a range of fundamental biological questions. We report a rationally designed probe with a 6'-fluoro spiropyran scaffold (5) for the reversible sensing of zinc (Zn2+) in cells.
