Separable Algorithmic Representations of Classical Systems and Their Applications
Современная математика: Фундаментальные направления, 2021 The main results of the theory of separable algorithmic representations of classical algebraic systems are presented. The most important classes of such systems and their representations in the lower classes of the arithmetic hierarchy - positive and ...

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry
FEBS Letters, EarlyView.EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Topological Algebra and its Applications, 2014 In 1964, Bertram Yood posed the following problem: whether the intersection of all closed maximal regular left ideals of a topological ring coincides with the intersection of all closed maximal regular right ideals of this ring.

Advances in Mathematics, 1994 Let \((R, \tau)\) be a topological ring and denote by \(N(\tau)\) the \(\tau\)-closure of \(\{0\}\) in \(R\). The author calls \(\tau\) a minimal ring topology if there is no ring topology \(\sigma\) on \(R\) strictly weaker than \(\tau\) with \(N(\sigma) = N(\tau)\).

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding
FEBS Letters, EarlyView.In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Experimental Observation of Dirac Nodal Links in Centrosymmetric Semimetal TiB_{2}
Physical Review X, 2018 The topological nodal-line semimetal state, serving as a fertile ground for various topological quantum phases, where a topological insulator, Dirac semimetal, or Weyl semimetal can be realized when the certain protecting symmetry is broken, has only ...

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

Spin-controlled topological phase transition in non-Euclidean space
Frontiers of OptoelectronicsModulation of topological phase transition has been pursued by researchers in both condensed matter and optics research fields, and has been realized in Euclidean systems, such as topological photonic crystals, topological metamaterials, and coupled ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research
FEBS Letters, EarlyView.What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

On a new radical in a topological ring [PDF]
Pacific Journal of Mathematics, 1973 The radical which is referred to in this paper was treated extensively by Wright in the case of topological groups. The present course of attack here is threefold: (1) to show the proximity of large powers of topologically nilpotent elements to the radical in a topological ring, (2) to determine a nilpotence condition on the radical and (3) to ...
