Epigenomic signature of accelerated ageing in progeroid Cockayne syndrome

Aging Cell, Volume 22, Issue 10, October 2023., 2023
We studied DNA methylation (DNAm) in a unique human model where impairment of the same protein results or not in a progeroid disease. Functional analyses of DNAm of accelerated ageing reveal enrichment in developmental transcription factors, ion/neurotransmitter transporters, and synaptic neurodevelopmental genes.

Quantum Lobachevsky planes [PDF]

Journal of Mathematical Physics, 1996
We classify all SL(2,R)-covariant Poisson structures on the Lobachevsky plane with respect to all multiplicative Poisson structures on SL(2,R) and describe quantizations for all these Poisson structures.

Tourist ethnocentrism: A bibliometric analysis based on Web of Science (WoS)

Family and Consumer Sciences Research Journal, Volume 52, Issue 1, Page 38-52, September 2023., 2023
Abstract The scientific literature regarding ethnocentrism is quite extensive in the fields of marketing, politics and psychology; however, in the realm of tourism it is barely mentioned and there is even less research. This study intends to fill the current bibliometric void in terms of the relationship between ethnocentrism and tourism. Its main goal

Barbier's Theorem in the Lobachevski Plane [PDF]

Proceedings of the American Mathematical Society, 1970
In the Lobachevski plane, horocycles with the same center are geodesic parallels and are natural replacements for the lines used in defining the support function of a convex curve and the notion of constant width in the Euclidean plane. In this paper, analogs based on horocycles are obtained for Christoffel’s formula, which expresses the radius of ...

Variability in Resistive Memories

Advanced Intelligent Systems, Volume 5, Issue 6, June 2023., 2023
A comprehensive review of variability in resistive memories is presented. Experimental evidence of variability for resistive memories is described. Later on, different approaches to model this variability from the physical, behavioral, and stochastic viewpoints are presented.

Fractal Information by Means of Harmonic Mappings and Some Physical Implications

Entropy, 2016
Considering that the motions of the complex system structural units take place on continuous, but non-differentiable curves, in the frame of the extended scale relativity model (in its Schrödinger-type variant), it is proven that the imaginary part of a ...

A Statistical Study of Resistive Switching Parameters in Au/Ta/ZrO2(Y)/Ta2O5/TiN/Ti Memristive Devices

physica status solidi (a), Volume 220, Issue 11, June 2023., 2023
Variability is an inherent property of memristive devices. For each specific structure, the variability should be measured and assessed. In this report, it is shown how this variability can be extracted and analyzed for such main parameters of resistive switching as the set and reset voltages/currents and how it depends on the methodology used and ...

A relative version of the Turaev–Viro invariants and the volume of hyperbolic polyhedral 3‐manifolds

Journal of Topology, Volume 16, Issue 2, Page 650-678, June 2023., 2023
Abstract We define a relative version of the Turaev–Viro invariants for an ideally triangulated compact 3‐manifold with nonempty boundary and a coloring on the edges, generalizing the Turaev–Viro invariants [36] of the manifold. We also propose the volume conjecture for these invariants whose asymptotic behavior is related to the volume of the manifold

A necessary flexibility condition of a nondegenerate suspension in Lobachevsky 3-space [PDF]

, 2012
We show that some combination of the lengths of all edges of the equator of a flexible suspension in Lobachevsky 3-space is equal to zero (each length is taken either positive or negative in this combination).Comment: 20 pages, 13 ...

N=1, D=3 Superanyons, osp(2|2) and the Deformed Heisenberg Algebra [PDF]

, 1997
We introduce N=1 supersymmetric generalization of the mechanical system describing a particle with fractional spin in D=1+2 dimensions and being classically equivalent to the formulation based on the Dirac monopole two-form.
