Square-root higher-order Weyl semimetals [PDF]
Nature Communications, 2022 The topological properties of square-root Weyl semimetals are derived from the square of the Hamiltonian. Here, the authors propose a tight-binding model for a square-root higher-order Weyl semimetal hosting both Fermi-arc surface and hinge states.

The Square-Root Unscented and the Square-Root Cubature Kalman Filters on Manifolds [PDF]
SensorsEstimating the state of a system by fusing sensor data is a major prerequisite in many applications. When the state is time-variant, derivatives of the Kalman filter are a popular choice for solving that task.

A square-root topological insulator with non-quantized indices realized with photonic Aharonov-Bohm cages. [PDF]
Nat Commun, 2020 Topological Insulators are a novel state of matter where spectral bands are characterized by quantized topological invariants. This unique quantized nonlocal property commonly manifests through exotic bulk phenomena and corresponding robust boundary ...

Review of Root-Mean-Square Error Calculation Methods for Large Deployable Mesh Reflectors
International Journal of Aerospace Engineering, 2022 In the design of a large deployable mesh reflector, high surface accuracy is one of ultimate goals since it directly determines overall performance of the reflector. Therefore, evaluation of surface accuracy is needed in many cases of design and analysis

Improved bounds for Square-Root Lasso and Square-Root Slope [PDF]
Electronic Journal of Statistics, 2018 Extending the results of Bellec, Lecu and Tsybakov to the setting of sparse high-dimensional linear regression with unknown variance, we show that two estimators, the Square-Root Lasso and the Square-Root Slope can achieve the optimal minimax prediction rate, which is $(s/n) \log (p/s)$, up to some constant, under some mild conditions on the design ...
