Twist-Related Speckle Variation in Graded-Index Multimode Fiber

IEEE Photonics Journal, 2018
We theoretically investigate a twist-related speckle variation in a graded-index multimode fiber. The simulation results show that by increasing the offset splicing distance between a single-mode fiber and a multimode fiber, the speckle pattern tends to ...

Propagation characteristics of photonic crystal fibers selectively filled with ionic liquid

Nanotechnology and Precision Engineering, 2021
We present a numerical and experimental study of the propagation characteristics of photonic crystal fibers (PCFs) selectively filled with ionic liquid (IL; 1-butyl-3-methylimidazolium iodine).

Twist Sensor Based on Long Period Grating and Tilted Bragg Grating Written in Few-Mode Fibers

IEEE Photonics Journal, 2018
A twist sensor based on a few-mode long period grating (LPG) and a tilted fiber Bragg grating (TFBG) is proposed and demonstrated. The LPG, inscribed in a step index few-mode fiber by a CO2 laser, is utilized to excite the LP11 core mode.

A biosensor based on a modified S-taper fiber for target protein detection

Nanotechnology and Precision Engineering, 2020
A biosensor based on a modified S-taper fiber was proposed and experimentally demonstrated for antigen detection. Antibody was immobilized over the activated S-taper waist, where the fiber detected the interaction between the antibody and target antigen.

A twist sensor based on polarization-maintaining fibers with different cladding diameters

Nanotechnology and Precision Engineering, 2021
A fiber twist sensor using a Sagnac interferometer incorporating a tapered polarization-maintaining fiber (PMF) is proposed. The transmission properties of the sensor are investigated both theoretically and experimentally.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Solid Pseudopapillary Neoplasm of the Pancreas in Children and Adolescents: Expert Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare low‐grade malignant exocrine pancreatic tumor, mostly discovered during the second decade of life in females, with a very good prognosis, provided microscopically complete surgical excision is achieved.
