Linear even order homogenous difference equation with delay in coefficient

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2020
We use many classical results known for the self-adjoint second-order linear equation and extend them for a three-term even order linear equation with a delay applied to coefficients.

Even-Order Aberration Cancellation in Quantum Interferometry [PDF]

open access: yesPhysical Review Letters, 2008
We report the first experimental demonstration of even-order aberration cancellation in quantum interferometry. The effect is a spatial counterpart of the spectral group velocity dispersion cancellation, which is associated with spectral entanglement.

Oscillation of even order nonlinear delay dynamic equations on time scales [PDF]

open access: yes, 1999
summary:One of the important methods for studying the oscillation of higher order differential equations is to make a comparison with second order differential equations. The method involves using Taylor's Formula. In this paper we show how such a method

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

open access: yesFEBS 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

On Sidon sequences of even orders [PDF]

open access: yesActa Arithmetica, 1993
Let \(h\geq 2\) be an integer. A set of positive integers \(A\) is called a \(B_ h\)-sequence, or a Sidon sequence of order \(h\), if all sums \(a_ 1+a_ 2+ \cdots+a_ h\), where \(a_ i\in B\) (\(i=1,2,\dots,h\)), are distinct up to rearrangements of the summands. Let \(A(n)\) be the cardinality of the set \(A\cap [0,n]\). It is proved that, for any \(B_{

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

open access: yesFEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Oscillatory criteria of noncanonical even-order differential equations with a superlinear neutral term

open access: yesBoundary Value Problems
The oscillatory behavior of solutions of an even-order differential equation with a superlinear neutral term is considered using Riccati and generalized Riccati transformations, the integral averaging technique, and the theory of comparison.

Mutual information for low-rank even-order symmetric tensor estimation

open access: yes, 2020
We consider a statistical model for finite-rank symmetric tensor factorization and prove a single-letter variational expression for its asymptotic mutual information when the tensor is of even order.

Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS 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 ...

Stabilizer Codes Over Fields of Even Order

open access: yesIEEE Transactions on Information Theory
We prove that the natural isomorphism between GF(2^h) and GF(2)^h induces a bijection between stabiliser codes on n quqits with local dimension q=2^h and binary stabiliser codes on hn qubits. This allows us to describe these codes geometrically: a stabiliser code over a field of even order corresponds to a so-called quantum set of symplectic polar ...
