A Wideband Closed-Loop Residual Current Sensor Based on Self-Oscillating Fluxgate

IEEE Access, 2023
The increasing switching frequency of inverters in new electric power technology causes leakage currents at tens or even hundreds of kHz, exceeding the measurement frequency range of conventional AC residual current sensors.

Transient Charging Dynamics in Stacked Ga2O3/ZnO Photovoltaic Units Governing Wavelength‐Selective Polarity Switching

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reveals a “Photovoltaic‐Capacitance” coupling mechanism in stacked Ga2O3/ZnO devices, defining the ZnO/graphene interface as a novel Photovoltaic Dynamic‐Capacitor (PDC). The wavelength‐selective bipolar response enables a physical layer secure communication protocol based on ternary optical logic (“1,” “0,” “−1”).

AMR Proximity Sensor With Inherent Demodulation [PDF]

, 2014
Our novel position sensor is based on the combination of the eddy-current and permeability effects. The primary field is excited by a coil, but instead of induction coil, the sensing part uses anisotropic magnetoresistor (AMR), which also measures dc ...

Too good to be true: Synthetic AI faces are more average than real faces and super‐recognizers know it

British Journal of Psychology, EarlyView.
Abstract The AI revolution has produced synthetic faces that often appear more human than photos of real people. We tested whether individual differences in human face recognition ability explain variation in discriminating AI from real faces. Super‐recognizers – people with exceptional ability to recognize human faces (N = 36) – outperformed a typical

Controllability of the moments for Khokhlov-Zabolotskaya-Kuznetsov (KZK) equation [PDF]

, 2006
Recalling the proprieties of the Khokhlov-Zabolotskaya-Kuznetsov(KZK) equation, we prove the controllability of moments result for the linear part of KZK equation.

Assessment of Pollen Production, Pollen Viability, Autofertility and Paternal Success in Faba Bean (Vicia faba L.) for Better Exploitation of Grain Yield Heterosis

Plant Breeding, EarlyView.
ABSTRACT In animal‐pollinated plants, pollen dispersal depends on several plant and animal characteristics that can influence the paternal success of a plant. Paternal success affects the genetic contribution of a genotype to the next generation, which is relevant to plant breeding.

Parlante superdireccional de matriz paramétrica [PDF]

, 2019
In this work, a directional loudspeaker, also known as a parametric array loudspeaker (PAL), is designed and constructed. The operation is based on the phenomenon called self-demodulation that happens when high-frequency beams interact in a viscous ...
