Multivariable Unconstrained Pattern Search Method for Optimizing Digital PID Controllers Applied to Isolated Forward Converter

open access: yesEnergies, 2020
Most of the traditional PID tuning methods are heuristic in nature. The heuristic approach-based tuned PID controllers show only nominal performance.

THE METHODOLOGY OF CIRCUIT CONSTRUCTION OF THE ANALOG VALUE CONVERTER IN THE TIMEFRAME

open access: yesИзмерение, мониторинг, управление, контроль, 2023
Background. Most modern digital voltmeters use an analog-to-digital converter (ADC) of the time-pulse type with two-stage integration, which takes place in two stages – integration and counting.

Lumped time-delay compensation scheme for coding synchronization in the nonlinear spectral quantization-based all-optical analog-to-digital conversion

open access: yes, 2013
In this paper, we propose a novel lumped time-delay compensation scheme for the all-optical analog-to-digital conversion based on soliton self-frequency shift and optical interconnection techniques.

A novel time to digital converter architecture for time of flight positron emission tomography

open access: yes, 2013
Positron emission tomography (PET) is a molecular imaging technique that provides images of physiological processes inside the body. In clinical applications, PET image quality benefits from the time of flight (TOF) feature.

Low-Resource Time-to-Digital Converters for Field Programmable Gate Arrays: A Review

open access: yesSensors
A fundamental aspect in the evolution of Time-to-Digital Converters (TDCs) implemented within Field-Programmable Gate Arrays (FPGAs), given the increasing demand for detection channels, is the optimization of resource utilization.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated
