Study on a probabilistic algorithm for the forming and 3D characterization of special-shaped surfaces under profile grinding
Profile grinding is the most crucial method for the ultra-precision machining of special-shaped surfaces. However, profile grinding produces a unique machining profile, and many random factors in the machining...

Open AccessRestoration of non-Hermitian bulk-boundary correspondence by counterbalancing skin effect
In systems exhibiting the non-Hermitian skin effect (NHSE), the bulk spectrum under open boundary conditions (OBC) significantly differs from that of its periodic counterpart. This disparity renders the conven...

Scalar topological photonic nested meta-crystals and skyrmion surface states in the light cone continuum
Topological photonics is rapidly expanding. However, discovering three-dimensional topological electromagnetic systems can be more challenging than electronic systems for two reasons. First, the vectorial natu...

Open AccessSymmetry-protected topological exceptional chains in non-Hermitian crystals
In non-Hermitian systems, defective band degeneracies called exceptional points can form exceptional lines (ELs) in 3D momentum space in the absence of any symmetries. However, whether the presence of symmetri...

Open AccessFour-band non-Abelian topological insulator and its experimental realization
Very recently, increasing attention has been focused on non-Abelian topological charges, e.g., the quaternion group Q8. Different from Abelian topological band insulators, these systems involve multiple entangled...

Experimental observation of non-Abelian topological charges and edge states
In the last few decades, topological phase1–11 has emerged as a new classification of matter states beyond the Ginzburg–Landau symmetry-breaking paradigm. The underlying global invariant is usually well character...

Open AccessEffects of intensity of electroacupuncture on chronic pain in patients with knee osteoarthritis: a randomized controlled trial
Conditioned pain modulation (CPM) is impaired in people with chronic pain such as knee osteoarthritis (KOA). The purpose of this randomized, controlled clinical trial was to investigate whether strong electroa...

Open AccessMetamaterials with index ellipsoids at arbitrary k-points
Propagation behaviors of electromagnetic waves are governed by the equifrequency surface of the medium. Up to now, ordinary materials, including the medium exist in nature and the man-made metamaterials, alway...

Open AccessA band of bound states in the continuum induced by disorder
Bound states in the continuum usually refer to the phenomenon of a single or a few discrete bound states embedded in a continuous spectrum of extended states. Here we propose a simple mechanism to achieve a ba...

Open AccessAnomalous Light Scattering by Topological PT-symmetric Particle Arrays
Robust topological edge modes may evolve into complex-frequency modes when a physical system becomes non-Hermitian. We show that, while having negligible forward optical extinction cross section, a conjugate p...

Open AccessSymmetry-protected transport in a pseudospin-polarized waveguide
If a system possesses a spin or pseudospin, which is locked to the linear momentum, spin-polarized states can exhibit backscattering-immune transport if the scatterer does not flip the spin. Good examples of s...

Open AccessElectroacupuncture inhibits chronification of the acute pain of knee osteoarthritis: study protocol for a randomized controlled trial
Previous studies have shown that electroacupuncture (EA) has a significant effect on acute pain, but it has not solved the clinical problem of the chronification of acute pain. Diffuse noxious inhibitory contr...

Open AccessDensity of States and Its Local Fluctuations Determined by Capacitance of Strongly Disordered Graphene
We demonstrate that fluctuations of the local density of states (LDOS) in strongly disordered graphene play an important role in determining the quantum capacitance of the top-gate graphene devices. Depending ...
