D-Shaped POF Sensors for Refractive Index Sensing—The Importance of Surface Roughness

Sensors, 2019
In this study the influence of the surface roughness on the transmission capacities of D-shaped plastic optical fibers (POFs) and sensors performance was investigated. Five D-shaped POF sensors were produced and characterized for refractive index sensing

Intensity-modulated radiotherapy - what is it? [PDF]

Cancer Imaging, 2004
Intensity-modulated radiotherapy (IMRT) is one of the most important recent developments in oncology. It enables precise conformation of the radiation dose to the target volume. It has the potential to significantly reduce long-term morbidity and improve local control.

Coherent Umklapp Scattering of Light from Disordered Photonic Crystals

, 2000
A theoretical study of the coherent light scattering from disordered photonic crystal is presented. In addition to the conventional enhancement of the reflected light intensity into the backscattering direction, the so called coherent backscattering (CBS)

Radiotherapy Delivery in Deep Inspiration for Pediatric Patients—Final Results of the Phase II Feasibility Study TEDDI

Pediatric Blood &Cancer, EarlyView.
Abstract Introduction The TEDDI trial tested the feasibility and reproducibility of deep‐inspiration breath‐hold (DIBH) in pediatric patients referred for radiotherapy. This report presents final results, including patient‐reported outcomes (PRO) and dosimetric comparison of DIBH and free‐breathing (FB).

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Transmission of 100-Gb/s PAM-6 Signal by Using DML Wavelength-Locked to Delay Interferometer

IEEE Photonics Journal
We experimentally demonstrate the transmission of 100-Gb/s 6-ary pulse amplitude modulation signal over 2-km standard single-mode fiber using a 1.55-μm directly-modulated laser (DML) wavelength-locked to a delay interferometer (DI).

SAR imagery of ocean-wave swell traveling in an arbitrary direction [PDF]

, 1984
The intensity wave like patterns observed in Synthetic Aperture Radar (SAR) are known to be caused by two mechanisms: the microwave radar cross sectional amplitude modulation due to tilt and hydrodynamic interaction of the long ocean waves, and intensity
