Radar Clutter Backscattering Simulation for Specific Sites [PDF]

open access: yes, 2007
The state of development of the surface clutter prediction model DORTE is presented. This simulation program utilizes Digital Elevation Models and land use information to calculate reflectivity maps for specific sites with optional statistical variation ...

Internal high-reflectivity omni-directional reflectors

open access: yes, 2018
An internal high-reflectivity omni-directional reflector (ODR) for the visible spectrum is realized by the combination of total internal reflection using a low-refractive-index (low-n) material and reflection from a one-dimensional photonic crystal (1D ...

High reflectivity grating waveguide coatings for 1064 nm [PDF]

open access: yes, 2006
We propose thin single-layer grating waveguide structures to be used as high reflectivity, but low thermal noise, alternative to conventional coatings for gravitational wave detector test mass mirrors.

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Diagnostic of laser contrast using target reflectivity

open access: yes, 2009
Using three different laser systems, we demonstrate a convenient and simple plasma based diagnostic of the contrast of high-power short-pulse lasers. The technique is based on measuring the specular reflectivity from a solid target.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Optimization of high reflectivity measurement by cavity ring-down technique

open access: yes, 2011
The reflectivity of cavity mirror has a great influence on output power and conversion efficiency of laser. Based on pulsed cavity ring-down (CRD) technology, a single wavelength reflectivity measuring system is set up.

A Fiber Optical Sensor For Non-Contact Vibration Measurements [PDF]

open access: yes, 2009
This paper describes an intensity based optical sensor for the evaluation of accelerations from non-contact displacement measurements. Plastic optical fibers are used to collect the reflected light from several points on the vibrating surface, allowing ...
