Computationally-Efficient Synchrophasor Estimation: Delayed In-Quadrature Interpolated DFT
Mario Paolone, Cesar Garcia Veloso
The paper proposes a synchropahsor estimation (SE) algorithm that leverages the use of a delayed in-quadrature complex signal to mitigate the self-interference of the fundamental tone. The estimator, which uses a three-point IpDFT combined with a three-cyc ...
2023Reticular chemistry for the rational design of mechanically robust mesoporous merged-net metal-organic frameworks
Berend Smit, Seyedmohamad Moosavi
Access to metal-organic frameworks (MOFs) with enhanced me-chanical stability is key to their successful deployment in practical applications. However, the high porosity of the material often af-fects mechanical stability. In this article, to achieve highl ...
CELL PRESS2023Influence of a lossy ground on the lightning performance of overhead transmission lines
Farhad Rachidi-Haeri, Rafael Silva Alipio
This paper investigates the impact of incorporating both displacement currents and frequency-dependent soil parameters in the calculation of the ground-return impedance for the determination of the backflashover rate of 138 kV and 230 kV overhead transmiss ...
2023Gigahertz free-space electro-optic modulators based on Mie resonances
Ileana-Cristina Benea-Chelmus, Sydney Rebecca Mason
Electro-optic modulators are essential for sensing, metrology and telecommunications. Most target fiber applications. Instead, metasurface-based architectures that modulate free-space light at gigahertz (GHz) speeds can boost flat optics technology by micr ...
NATURE PORTFOLIO2022Phase Reconstruction of Low-Energy Electron Holograms of Individual Proteins
Klaus Kern, Stephan Rauschenbach, Sven Alexander Szilagyi, Hannah Julia Ochner
Low-energy electron holography (LEEH) is one of the few techniques capable of imaging large and complex three-dimensional molecules, such as proteins, on the single molecule level at subnanometer resolution. During the imaging process, the structural infor ...

Edoardo Charbon, Andrea Ruffino, Yatao Peng
In this article, a cryo-CMOS receiver integrated with a frequency synthesizer for scalable multiplexed readout of qubits is presented, focusing on radio frequency (RF) reflectometry readout of silicon-based semiconductor spin qubits/quantum dots. The propo ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022Amplitude and phase reconstruction for Low-Energy Electron Holography of individual proteins
Single-molecule imaging methods are of importance in structural biology, and specifically in the imaging of proteins, since they can elucidate conformational variability and structural changes that might be lost in imaging methods relying on averaging proc ...
EPFL2022Slice-Less Optical Arbitrary Waveform Measurement (OAWM) in a Bandwidth of More Than 600 GHz
Tobias Kippenberg, Grigorii Likhachev
We demonstrate an optical arbitrary waveform measurement (OAWM) technique that exploits optical frequency combs as multi-wavelength local oscillators (LO) and that does not require any optical slicing filters. In a proof-of-concept experiment, we achieve r ...
IEEE2022Implantable Neuro-Modulation Devices and Technology
Implantable electronic medical devices that operate in closed-loop allow efficient neuro-modulation. Area and power are to be carefully balanced to improve the system autonomy and safety. New digital modulation schemes with implementation in the front-end ...
