We demonstrate the multiparametric monitoring of directional bending, torsion, and temperature based on helical long-period gratings (HLPGs) in a triangular four-core fiber (FCF) using CO 2 laser i…
Negative curvature hollow core fiber (NC-HCF) with elliptical tubes is beneficial for low confinement loss (CL) due to the rich degree of freedom in tube curvature. In this paper, an empirical form…
An effective person re-identification (re-ID) model should learn feature representations that are both discriminative, for distinguishing similar-looking people, and generalisable, for deployment a…
In this paper, we demonstrate the transmission spectral and surrounding refractive index (SRI) sensing performance of long-period fiber gratings (LPFGs) at 2 μm waveband. The cladding modes operat…
An effective method, reducing the material volume of the air cavity by asymmetrical tapering fiber, is demonstrated to enhance the sensitivity of the strain sensor dramatically. High-sensitive stra…
We study whether sell-side financial analysts’ physical attractiveness is associated with their job performance. We find that attractive analysts make more accurate earnings forecasts than less a…
For every element x of a finite group G, there always exists a unique minimal subnormal subgroup, say, Gx of G such that x∈Gx. The sub-class of G in which x lies is defined by {xg∣g∈Gx}. The …
In this paper we classify the finite solvable groups in which distinct nonlinear monomial characters have distinct degrees.
