Dynamical difference equations
AbstractDynamical difference equations are motivated and developed. Conservation and covariance laws are proved. Illustrative examples are described and discussed. Newtonian equations are stressed, but extensions to relativity and quantum mechanics are indicated. The physical problem of convergence to the limit as the time step goes to zero is shown to

On the Solutions of Difference Equation Systems with Padovan Numbers
In this study, we investigate the form of the solutions of the following rational difference equation systems 1 1 1 1 , n n nn x x yx 1 1 1 n n nn y y xy such that their solutions are associated with Padovan numbers.

UDP‐glucuronic acid 4‐epimerase (UGAepi) catalyzes NAD+‐dependent interconversion of UDP‐glucuronic acid (UDP‐GlcA) and UDP‐galacturonic acid (UDP‐GalA) via C4‐oxidation, 4‐keto‐intermediate rotation, and C4‐reduction. Here, Borg et al. examined the role of the substrate's carboxylate group in the enzymic mechanism by analyzing NADH‐dependent reduction

On the solutions of two special types of Riccati difference equation via Fibonacci numbers
In this study, we investigate the solutions of two special types of the Riccati difference equation xn+1=11+xn and yn+1=1−1+yn such that their solutions are associated with Fibonacci numbers.MSC: 11B39, 39A10, 39A13.

Glutaredoxin (Grx) 3 proteins contain a thioredoxin domain and one to three class II Grx domains. These proteins play a crucial role in iron homeostasis in eukaryotic cells. In human Grx3, at least one of the two Grx domains, together with the thioredoxin domain, is essential for its function in iron metabolism.

Difference equation of the colored Jones polynomial for torus knot
We prove that the N-colored Jones polynomial for the torus knot T_{s,t} satisfies the second order difference equation, which reduces to the first order difference equation for a case of T_{2,2m+1}.

A stochastic difference equation
where a(.) and t(.) are random processes with values, respectively, in the non-negative reals, and 5%““. That is, a(n, w) and c(n, w) depend on LL, in a common probability space 0, and (0.1) is assumed to hold for every n ENi for almost every o E 8.

Dimeric pyruvate formate‐lyase cleaves pyruvate using a radical‐based mechanism. G734 serves as a radical storage location, and the radical is transferred to the catalytic C419 residue. Mutation of the C418‐C419 pair causes loss of enzyme activity, but does not impede radical introduction onto G734. Therefore, cis‐ but not trans‐radical transfer occurs

To explore the impact of the overexpression of the multidrug‐transporter P‐glycoprotein (ABCB1) on membrane fluidity, we compared the transversal gradient of mobility and microviscosity in plasma membranes of drug‐sensitive Chinese hamster ovary cells (AuxB1) and their multidrug‐resistant derivatives (B30) using the fluorescent n‐(9‐anthroyloxy) fatty ...

On difference equation with generalized dilation
We investigate the functional equation with generalized dilation in the special weighted functional spaces. We provide some sufficient conditions for the existence of the inversion operator in the same form and consider several examples.
