p-topological Cauchy completions
International Journal of Mathematics and Mathematical Sciences, 1999 The duality between “regular” and “topological” as convergence space properties extends in a natural way to the more general properties “p-regular” and “p-topological.” Since earlier papers have investigated regular, p-regular, and topological Cauchy ...

Observation of topological valley transport of sound in sonic crystals [PDF]
Nature Physics, 2016 Valleytronics — exploiting a system’s pseudospin degree of freedom — is being increasingly explored in sonic crystals. Now, valley transport of sound is reported for a macroscopic triangular-lattice array of rod-like scatterers in a 2D air waveguide. The

On i-topological spaces: generalization of the concept of a topological space via ideals
Applied General Topology, 2006 The aim of this paper is to generalize the structure of a topological space, preserving its certain topological properties. The main idea is to consider the union and intersection of sets modulo “small” sets which are defined via ideals.

Momentum-space imaging of Cooper pairing in a half-Dirac-gas topological superconductor [PDF]
Nature Physics, 2014 Superconductivity involving topological Dirac electrons has recently been proposed as a platform between concepts in high-energy and condensed-matter physics. It has been predicted that supersymmetry and Majorana fermions, both of which remain elusive in

An operation on topological spaces
Applied General Topology, 2000 <p>A (binary) product operation on a topological space X is considered. The only restrictions are that some element e of X is a left and a right identity with respect to this multiplication, and that certain natural continuity requirements are satisfied. The operation is called diagonalization (of X). Two problems are considered: 1.

On partition of topological spaces [PDF]
Časopis pro pěstování matematiky, 1984 The authors study the problem of the existence of a Hausdorff space Y such that, for each \(A\subset Y\), the Cantor discontinuum is (homeomorphic to) a subspace of A or of \(Y-A.\) They make significant contributions to this problem. Theorem. [ACP{\#}]\(\vee [V=L\)].

Evolutionary interplay between viruses and R‐loops
FEBS Letters, EarlyView.Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Topological Signal Processing Over Simplicial Complexes [PDF]
IEEE Transactions on Signal Processing, 2019 The goal of this paper is to establish the fundamental tools to analyze signals defined over a topological space, i.e. a set of points along with a set of neighborhood relations.

Exploring lipid diversity and minimalism to define membrane requirements for synthetic cells
FEBS Letters, EarlyView.Designing the lipid membrane of synthetic cells is a complex task, in which its various roles (among them solute transport, membrane protein support, and self‐replication) should all be integrated. In this review, we report the latest top‐down and bottom‐up advances and discuss compatibility and complexity issues of current engineering approaches ...
