Compressive image sensor architecture with on-chip measurement matrix generation [PDF]

open access: yes, 2017
A CMOS image sensor architecture that uses a cellular automaton for the pseudo-random compressive sampling matrix generation is presented. The image sensor employs in-pixel pulse-frequency modulation and column wise pulse counters to produce compressed ...

Vaccination Strategies and Immune Modulation of Atherosclerosis [PDF]

open access: yesCirculation Research, 2020
Adaptive as well as innate immune responses contribute to the development of atherosclerosis. Studies performed in experimental animals have revealed that some of these immune responses are protective while others contribute to the progression of disease.

Low-Carrier-Ratio Modulation Strategy Based on Improved Flux Ripple Model

open access: yesEnergies, 2022
Since the quality of the direct and quadrature axis current (dq-axis) is an important performance indicator of a motor, the technique of flux ripple analysis is necessary to determine the appropriate working conditions for various voltage sequences and ...

Synthetic Analogues of the Snail Toxin 6-Bromo-2-mercaptotryptamine Dimer (BrMT) Reveal That Lipid Bilayer Perturbation Does Not Underlie Its Modulation of Voltage-Gated Potassium Channels [PDF]

open access: yes, 2018
Drugs do not act solely by canonical ligand–receptor binding interactions. Amphiphilic drugs partition into membranes, thereby perturbing bulk lipid bilayer properties and possibly altering the function of membrane proteins.

Improved Modulation Strategy Based on Minimum Energy Storage Principle for Electrolytic-Capacitor-Less Six-Switch Converter

open access: yesApplied Sciences, 2021
An improved modulation strategy based on minimum energy storage for DC-link capacitance reduction in a six-switch AC-AC converter is proposed. The proposed modulation strategy enables the energy on the capacitor to accumulate and release twice each in a ...

Implementation of a Novel Variable Structure Nearest Level Modulation on Cascaded H-Bridge Multilevel Inverter

open access: yesIEEE Access, 2021
The output voltage of a Multilevel Inverter (MLI) can be controlled using various low and high frequency modulation strategy. Apart from meeting the load voltage demand, the modulation strategy also tries to reduce the harmonics present in the output ...

A Cooperative Network Coding Strategy for the Interference Relay Channel. [PDF]

open access: yes, 2012
In this paper, we study an interference relay network with a satellite as relay. We propose a cooperative strategy based on physical layer network coding and superposition modulation decoding for uni-directional communications among users.

Molecular strategies for modulating Wnt signaling

open access: yesFrontiers in Bioscience, 2017
The importance of the Wnt signaling cascade in the fields of developmental biology, regenerative medicine, cancer genetics, and neurobiology has fueled a wide search for potent pharmacological agents capable of controlling Wnt signaling. Numerous fields of study have lent assistance to this endeavor, yielding both natural and synthetic compounds that ...

Towards quantitative tissue absorption imaging by combining photoacoustics and acousto-optics [PDF]

open access: yes, 2012
We propose a strategy for quantitative photoacoustic mapping of chromophore concentrations that can be performed purely experimentally. We exploit the possibility of acousto-optic modulation using focused ultrasound, and the principle that photons follow

Frequency-modulated nuclear localization bursts coordinate gene regulation [PDF]

open access: yes, 2008
In yeast, the transcription factor Crz1 is dephosphorylated and translocates into the nucleus in response to extracellular calcium. Here we show, using time-lapse microscopy, that Crz1 exhibits short bursts of nuclear localization (typically lasting 2 ...
