Molecular Oncology, EarlyView.This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

Applied Optics, 1981
This paper describes the fabrication process and coupling principle of a single-mode fiber coupler. Precise etching properties of the fibers used are presented. Fiber etching is shown to result in smooth surfaces. Coupling is seen to vary with the refractive index of the material separating the fiber cores.

Single-mode optical waveguides
Applied Optics, 1979An efficient and powerful technique has been developed to treat the problem of wave propagation along arbitrarily shaped single-mode dielectric waveguides with inhomogeneous index variations in the cross-sectional plane. This technique is based on a modified finite-element method.

Investigation on Single-Mode-Multimode-Single-Mode Fiber Structure
2011 Symposium on Photonics and Optoelectronics (SOPO), 2011The multimode interference (MMI) theory and corresponding re-imaging phenomena occurring in a single - mode-multimode-single-mode (SMS) fiber structure is investigated. And the commercially available beam propagation method (BPM) have been adapted and analyzed to model the light propagation in this structure.

Proceedings of the IEEE, 1987
A variety of optical components have been made directly from single-mode fibers. These components can be combined to construct in-line all-fiber systems such as fiber gyroscopes, fiber Raman lasers, local area networks, or coherent lightwave systems. This paper reviews the present state of passive and active single-mode fiber components.

We present a solution to maintain an expanded mode in the extremity of a single mode fiber by using a piece-of multimode step index fiber. With a 25 /spl mu/m spot size, the average connection loss is 0.36 dB (without Fresnel reflection) for a multimode section length inferior to 5 cm.

Polarization maintaining Single-mode fibers
Conference on Lasers and Electro-Optics, 1981Polarization-maintaining single-mode fibers will find application in acoustooptic sensors and fiber gyroscopes. In this study both stress-induced birefringence and elliptical core polarization-maintaining single-mode fibers were developed and evaluated.
