Simulation of TiN/HfO2/Pt memristor I–V curve for different conductive filament thickness [PDF]
Modern Electronic Materials, 2021 The operation of the TiN/HfO2/Pt bipolar memristor has been simulated by the finite elements method using the Maxwell steady state equations as a mathematical basis.

Robust uncertainty principles: exact signal reconstruction from highly incomplete frequency information [PDF]
IEEE Transactions on Information Theory, 2004 This paper considers the model problem of reconstructing an object from incomplete frequency samples. Consider a discrete-time signal f/spl isin/C/sup N/ and a randomly chosen set of frequencies /spl Omega/.

Conv-TasNet: Surpassing Ideal Time–Frequency Magnitude Masking for Speech Separation [PDF]
IEEE/ACM Transactions on Audio Speech and Language Processing, 2018 Single-channel, speaker-independent speech separation methods have recently seen great progress. However, the accuracy, latency, and computational cost of such methods remain insufficient.

A continuum of bright and dark-pulse states in a photonic-crystal resonator
Nature Communications, 2022 A Kerr-nonlinear resonator with normal dispersion supports bright and dark pulse states. With photonic crystal ring resonators, this work demonstrates a continuum across these nonlinear states and explores the underlying mechanism.

A Dual-Band Dual-Polarized Base Station Antenna Array With Isolation Enhancement
IEEE Open Journal of Antennas and Propagation, 2023 In this paper, a dual-band dual-polarized antenna with isolation enhancement is designed. The proposed antenna operates in the frequency range of 3.4–3.6 GHz and 4.8-5 GHz, where the center frequency of the high band (HB) is 1.4 times that of the ...

Beyond Low-frequency Information in Graph Convolutional Networks [PDF]
AAAI Conference on Artificial Intelligence, 2021 Graph neural networks (GNNs) have been proven to be effective in various network-related tasks. Most existing GNNs usually exploit the low-frequency signals of node features, which gives rise to one fundamental question: is the low-frequency information ...

Generalizing Face Forgery Detection with High-frequency Features [PDF]
Computer Vision and Pattern Recognition, 2021 Current face forgery detection methods achieve high accuracy under the within-database scenario where training and testing forgeries are synthesized by the same algorithm. However, few of them gain satisfying performance under the cross-database scenario

Inference of Population Splits and Mixtures from Genome-Wide Allele Frequency Data [PDF]
PLoS Genetics, 2012 Many aspects of the historical relationships between populations in a species are reflected in genetic data. Inferring these relationships from genetic data, however, remains a challenging task. In this paper, we present a statistical model for inferring
