Fiber Fabry-Perot cavity with high finesse [PDF]

, 2010
We have realized a fiber-based Fabry-Perot cavity with CO2 laser-machined mirrors. It combines very small size, high finesse F>=130000, small waist and mode volume, and good mode matching between the fiber and cavity modes.

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Design and applicability analysis of independent double acquisition circuit of all-fiber optical current transformer

Global Energy Interconnection, 2019
The advantages of the all-fiber optical current transformer include but are not limited to being small in size, having no magnetic saturation, exhibiting high measurement accuracy, and boasting strong electromagnetic interference resistance. However, the

Nonlinear Frequency-Division Multiplexing in the Focusing Regime [PDF]

, 2016
Achievable rates of the nonlinear frequency-division multiplexing (NFDM) and wavelength-division multiplexing (WDM) subject to the same power and bandwidth constraints are computed as a function of transmit power in the standard single-mode fiber.

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

Molecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

Convenient connectorization technique between single mode polymer optical fiber and single mode silica optical fiber

Eighth Symposium on Novel Photoelectronic Detection Technology and Applications, 2022
Bragg gratings can now be produced in various types of polymer optical fibers. However, compared to silica optical fibers, it is still difficult to obtain highly reflective gratings in polymer optical fibers because of material swelling resulting from larger UV absorption.

An optical fiber hydrogen sensor using a palladium-coated ball lens [PDF]

, 2015
A self-referenced optical fiber refractometer using a ball lens as a sensor head has been developed and characterized. A 350-μm ball lens created at the tip of a single mode fiber has been coated with a 40-nm optically thin layer of palladium that reacts

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Toward a compact fibered squeezing parametric source

, 2018
In this work, we investigate three different compact fibered systems generating vacuum squeezing that involve optical cavities limited by the end surface of a fiber and by a curved mirror and containing a thin parametric crystal.
