Ferroelectric switching of a two-dimensional metal
Nature, 2018 A ferroelectric is a material with a polar structure whose polarity can be reversed (switched) by applying an electric field1,2. In metals, itinerant electrons screen electrostatic forces between ions, which explains in part why polar metals are very ...

Spin-Torque Switching with the Giant Spin Hall Effect of Tantalum [PDF]
Science, 2012 Giant Spin Hall One of the primary challenges in the field of spin-electronics, which exploits the electron's spin rather than its charge, is to create strong currents of electrons with polarized spins.

Switching Convolutional Neural Network for Crowd Counting [PDF]
Computer Vision and Pattern Recognition, 2017 We propose a novel crowd counting model that maps a given crowd scene to its density. Crowd analysis is compounded by myriad of factors like inter-occlusion between people due to extreme crowding, high similarity of appearance between people and ...

Single-shot dynamics of spin–orbit torque and spin transfer torque switching in three-terminal magnetic tunnel junctions [PDF]
Nature Nanotechnology, 2020 Current-induced spin-transfer torques (STT) and spin–orbit torques (SOT) enable the electrical switching of magnetic tunnel junctions (MTJs) in non-volatile magnetic random access memories.

Sensors, 2022 Recently, the joint estimation for time delay (TD) and direction of arrival (DOA) has suffered from the high complexity of processing multi-dimensional signal models and the ineffectiveness of correlated/coherent signals.

Robust direct position determination methods in the presence of array model errors
EURASIP Journal on Advances in Signal Processing, 2018 Direct position determination (DPD) methods are known to have many advantages over the traditional two-step localization method, especially for low signal-to-noise ratios (SNR) and/or short data records.

CRLB for joint estimation of TDOA, phase, FDOA, and Doppler rate
The Journal of Engineering, 2019 To avoid decline of FDOA estimation precision caused by relative Doppler companding, Doppler rate has to be considered and estimated jointly with TDOA, phase, and FDOA. However, CRLB of the joint estimation is still unclear.

Physical Layer Key Generation Scheme Through Scrambling the Correlated Eavesdropping Channel
IEEE Access, 2020 In this paper, we investigate the physical layer key generation scheme in most realistic scenarios where the correlation between the legitimate channel and the eavesdropping channel is considered. To degrade the correlation and improve the key generation

Algebraic distributed source localisation algorithm using TDOA and AOA measurements
The Journal of Engineering, 2019 This study proposes an algebraic distributed source localisation algorithm that combines time difference of arrival (TDOA) and angle of arrival (AOA) measurements. The proposed algorithm uses AOAs to remove the unknown parameters in TDOA equations caused
