Comparison of Fluidic and Non-Fluidic Surface Plasmon Resonance Biosensor Variants for Angular and Intensity Modulation Measurements [PDF]

open access: yesSensors, 2023
Fluidic and non-fluidic surface plasmon resonance measurements were realized for the same type of sensory layer and using the same mouse IgG antibody and anti-mouse IgG antibody biomolecular system.

Intensity Modulation of Pseudocolor Images [PDF]

open access: yesBioTechniques, 1998
Fura-2 is a popular real-time fluorescent indicator used to image intracellular, free calcium concentrations ([Ca2+]i) in living cells. One difficulty with fura-2-based digital imaging is how to best display the [Ca2+]i information that is acquired ...

Asymmetrically Clipped Optical Hadamard Coded Modulation (ACO-HCM)

open access: yesIEEE Photonics Journal, 2023
In many optical wireless communications systems, power efficiency is paramount. In others, flexibility is important. To achieve these goals, this paper presents a novel transmission scheme dubbed asymmetrically clipped optical Hadamard coded modulation ...

Acoustic Focusing with Intensity Modulation Based on Sub-Wavelength Waveguide Array

open access: yesCrystals, 2021
Acoustic focusing with intensity modulation plays an important role in biomedical and life sciences. In this work, we propose a new approach for simultaneous phase and amplitude manipulation in sub-wavelength coupled resonant units, which has not been ...

An Optically Pumped Magnetometer with Omnidirectional Magnetic Field Sensitivity

open access: yesSensors, 2023
In mobile applications such as geomagnetic surveying, two major effects hamper the use of optically pumped magnetometers: dead zones, sensor orientations where the sensors signal amplitude drops; and heading errors, a dependence of the measured magnetic ...

Bandlimited Intensity Modulation [PDF]

open access: yesIEEE Transactions on Communications, 2012
In this paper, the design and analysis of a new bandwidth-efficient signaling method over the bandlimited intensity-modulated direct-detection (IM/DD) channel is presented. The channel can be modeled as a bandlimited channel with nonnegative input and additive white Gaussian noise (AWGN).

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

open access: yesCancer 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.

Intensity modulated proton therapy [PDF]

open access: yesThe British Journal of Radiology, 2015
Intensity modulated proton therapy (IMPT) implies the electromagnetic spatial control of well-circumscribed "pencil beams" of protons of variable energy and intensity. Proton pencil beams take advantage of the charged-particle Bragg peak-the characteristic peak of dose at the end of range-combined with the modulation of pencil beam variables to create ...
