The consistency of estimator under fixed design regression model with NQD errors
In this article, basing on NQD samples, we investigate the fixed design
nonparametric regression model, where the errors are pairwise NQD random
errors, with fixed design points, and an unknown function. Nonparametric
weighted estimator will be introduced and its consistency is studied. As
special case, the consistency result for weighted kernel estimators of the
model is obtained. This extends the earlier work on independent random and
dependent random errors to NQD case
Prediction of a missing higher charmonium around 4.26 GeV in family
Inspired by the similarity of mass gaps of and families,
the prediction of missing higher charmonium with mass MeV and very
narrow width is made. In addition, the properties of two charmonium-like
states, and , and charmonium are discussed.
Here, as is established while the explanation of
to be is fully excluded and is typically a
very narrow state. These predictions can be accessible at BESIII, Belle and
BelleII in near future.Comment: 5 pages, 5 figures and 1 table. More discussions added. Accepted by

Signal Processing for Nondifferentiable Data Defined on Cantor Sets: A Local Fractional Fourier Series Approach
From the signal processing point of view, the nondifferentiable data defined on the Cantor sets are investigated in this paper. The local fractional Fourier series is used to process the signals, which are the local fractional continuous functions. Our results can be observed as significant extensions of the previously known results for the Fourier series in the framework of the local fractional calculus. Some examples are given to illustrate the efficiency and implementation of the present method
Topological phase transition and nontrivial thermal Hall signatures in honeycomb lattice magnets
We investigate spinon band topology and engineering from the interplay
between long-ranged magnetic order and fractionalized spinons, as well as
Zeeman coupling under external magnetic fields, in honeycomb lattice magnets.
The synergism of N\'eel order and magnetic fields could reconstruct the spinon
bands and drive a topological phase transition from the coexisting phase of
long-ranged order and chiral spin liquid with semion topological order to the
conventional magnetic order. Our prediction can be immediately tested through
thermal Hall transport measurements among the honeycomb lattice magnets that
are tuned to be proximate to the quantum critical point. Our theory should also
shed light on the critical behavior of honeycomb Kitaev materials with emergent
Majorana fermion bands. We suggest a possible relevance to the spin-1/2
honeycomb spin liquid candidate material InCuVO.Comment: 6 figures, may submit to a domestic journal of China, paper
