Spectral identification of topological domains [PDF]
Bioinformatics, 2016 Abstract Motivation: Topological domains have been proposed as the backbone of interphase chromosome structure. They are regions of high local contact frequency separated by sharp boundaries. Genes within a domain often have correlated transcription.

Autonomous Decentralized Spectral Clustering for Hierarchical Routing of Multi-Hop Wireless Networks
IEEE Access, 2023 In multi-hop wireless networks (MWNs), hierarchical structures are important to achieve scalable routing control, as well as clustering algorithms for creating such structures and so have been extensively studied.

Quantized classical response from spectral winding topology
Nature Communications, 2021 Quantized response has so far eluded classical system beyond linear response theory. Here, the authors predict that a quantized classical response, arising from fundamental mathematical properties of the Green’s function, shows up in steady-state ...

A topological approach to spectral clustering
Foundations of Data Science, 2021 We propose two related unsupervised clustering algorithms which, for input, take data assumed to be sampled from a uniform distribution supported on a metric space $X$, and output a clustering of the data based on the selection of a topological model for the connected components of $X$.

The spectral topology in rings [PDF]
Studia Mathematica, 2010 The spectral topology of a ring is easily defined, has familiar applications in elementary Banach algebra theory, and appears relevant to abstract Fredholm and stable range theory. 0. Introduction. The spectral topology of a ring is motivated by the simple Banach algebra observation that, for x ∈ A, (0.1) ‖x‖ < 1 ⇒ 1− x ∈ A−1.

Topological strings and quantum spectral problems [PDF]
Journal of High Energy Physics, 2014 We consider certain quantum spectral problems appearing in the study of local Calabi-Yau geometries. The quantum spectrum can be computed by the Bohr-Sommerfeld quantization condition for a period integral. For the case of small Planck constant, the periods are computed perturbatively by deformation of the Omega background parameters in the Nekrasov ...

Spectral-Topological Superefficient Quantum Memory [PDF]
Scientific Reports, 2019 AbstractIn this work, we propose a universal (spectral-topological) approach towards the realization of the quantum memory, consisting of a small number of controlled absorbers, providing a super-high quantum efficiency of more than 99.9% required for practical quantum information science.

Ramanujan graphs and the spectral gap of supercomputing topologies [PDF]
The Journal of Supercomputing, 2020 Graph eigenvalues play a fundamental role in controlling structural properties, such as bisection bandwidth, diameter, and fault tolerance, which are critical considerations in the design of supercomputing interconnection networks. This motivates considering graphs with optimal spectral expansion, called Ramanujan graphs, as potential candidates for ...
