The vector field problem for homogeneous spaces [PDF]

open access: yesarXiv, 2018
The vector field problem is an important and classical problem in differential topology. In this survey we shall consider the vector field problem focusing mainly on the class of compact homogeneous spaces.

CeiTEA: Adaptive Hierarchy of Single Cells with Topological Entropy

open access: yesAdvanced Science, EarlyView.
CeiTEA, a novel hierarchical clustering algorithm based on topological entropy, effectively captures complex structures underlying data. By constructing an adaptive multi‐nary partition tree, CeiTEA reveals hierarchical structures and local diversifications, outperforming existing methods in clustering accuracy and consistency and providing the ...

Twist Gating of a Graphene Nanoribbon

open access: yesAdvanced Electronic Materials, EarlyView.
It is shown that twisting of a hexa‐peri‐hexabenzocoronene nanoflake on an armchair graphene nanoribbon can modulate the current through the nanoribbon by 25% due to modulated scattering as a consequence of changes in the orbital overlap. Abstract Employing first‐principles calculations and the non‐equilibrium Green's function method, a hexa‐peri ...

Polar fuzzy topologies on fuzzy topological vector spaces [PDF]

open access: yesarXiv, 2019
In this paper, we introduce the concept of polar fuzzy sets on fuzzy dual spaces. Using the notion of polar fuzzy sets, we define polar linear fuzzy topologies on fuzzy dual spaces and prove the Mackey-Arens type Theorem on fuzzy topological vector ...

Electronic CPA‐Laser Having Enhanced Sensitivity and Tunability

open access: yesAdvanced Electronic Materials, EarlyView.
Coherent perfect absorber (CPA) laser points are peculiar singularities possessed by parity−time symmetric systems. They have demonstrated great potential for sensing applications, albeit hindered by the non‐tunability and structural limitations. This work introduces a tunable CPA laser system in a reader‐sensor scheme, whose sensitivity can be further

Construction of hybrid 1D‐0D networks for efficient and accurate blood flow simulations

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 95, Issue 2, Page 262-312, February 2023., 2023
A set of coupling equations to appropriately couple nonlinear 1D and lumped‐parameter (0D) models for blood flow in compliant vessels is defined. Then, a methodology for the high‐order numerical coupling between 1D and 0D vessels through hybrid junctions is proposed.
