IEEE Access, 2020 We report on a novel weakly-coupled 6-LP-mode fiber that features a nanopore-assisted step-index core with double-cladding profile. The purpose of this fiber design is to alleviate modes coupling and bend sensitivity, thus simplifies the multiple-input ...

Bend loss in structured optical fibres
Optics Express, 2007 Bend loss characterisation tests are carried out in two air-silica structured fibres: a periodic photonic crystal fibre and a non-periodic fibre. An explanation based on resonant coupling between interstitial zones accounts for the improved confinement of non-periodic structured optical fibres.

Crystals, 2023 In this paper, a low-loss 90°-bending design in femtosecond laser-induced double-line waveguides is theoretically proposed and experimentally demonstrated. The bending is realized based on the total internal reflection of a corner mirror (made by precise

Bend loss in highly multimode fibres
Optics Express, 2008 We investigate the bend loss of highly multimode air-clad microstructured polymer optical fibre which displays low bend loss for small bend radii. After repeated bending the loss approached a plateau, decreasing significantly after a characteristic length. The loss at a particular point depended on the configuration of the fibre preceding that point. A

Bending loss of terahertz pipe waveguides
Optics Express, 2010 We present an experimental study on the bending loss of terahertz (THz) pipe waveguide. Bending loss of pipe waveguides is investigated for various frequencies, polarizations, core diameters, cladding thicknesses, and cladding materials. Our results indicate that the pipe waveguides with lower guiding loss suffer lower bending loss due to stronger mode

IEEE Photonics Journal, 2023 Hollow-core anti-resonant fibers (HC-ANF) have the advantages of low scattering loss, wide bandwidth and simplicity of preparation, but are sensitive to bend, which limits their practical applications.

Molecular Oncology, EarlyView.Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.

FEBS Open Bio, EarlyView.TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

Ionomycin suppresses cancer cell growth by disrupting mitochondrial transcription
FEBS Open Bio, EarlyView.In this study, we identify a new function for the selective Ca2+ ionophore, ionomycin, as an inhibitor of mitochondrial transcription. Both total and nascent RNA analyses revealed that ionomycin treatment reduces the transcription of mitochondrial genes.

Development and performance testing of OTDR-based twisted fiber optic strain sensors
Meitan kexue jishuTo accurately monitor the deformation patterns of rock masses in high-stress soft rock tunnels, a coiled optical fiber strain sensor was developed using optical time-domain reflectometry.
