Establishing Atomic Coherence in Twisted Oxide Membranes Containing Volatile Elements

Advanced Materials, EarlyView.
Twisted oxide membranes containing volatile elements often suffer from amorphous interfacial dead layers that suppress coupling. An oxygen‐annealing strategy establishes atomically coherent and chemically bonded interfaces in twisted NaNbO3 membranes, enabling coherent oxide moiré architectures in volatile‐element‐containing systems.

Soft Skins With Reversible Thickness Morphing: Materials, Mechanisms, and Applications

Advanced Materials, EarlyView.
Evolution of electronic skin (e‐skin) technologies toward adaptive, multifunctional soft skins. Phase I highlights early rigid and discrete sensory interfaces. Phase II shows the transition toward flexible, stretchable, and large‐area e‐skin. Phase III captures the emergence of computational e‐skin.

Nano‐Architected Metallic Metamaterial With Enhanced Fatigue Resistance via Dislocation Starvation

Advanced Materials, EarlyView.
Nanoscale Ni single crystals exhibit remarkable fatigue resistance over an order of magnitude higher than that of bulk single crystals through dislocation starvation. By translating this mechanism into geometric nano‐architecture, nano‐architected Ni single‐crystal metamaterials achieve about twice the fatigue resistance of the bulk, despite their ...

Polymeric Sorbents as Energy‐Efficient Alternative to Cryogenic Distillation for Light Hydrocarbon Purification

Advanced Materials, EarlyView.
The transition from cryogenic distillation to polymeric sorbents for light hydrocarbon purification is crucial for energy and environmental sustainability. The polymeric sorbents are engineered to separate gas mixtures based on their specific properties.

Noise suppressing apparatus and noise suppressing method

The Journal of the Acoustical Society of America, 2006
Speech/non-speech determining section 103 makes a speech/non-speech determination of whether a speech spectrum is of a speech interval with a speech included or of a non-speech interval with only a noise and no speech included. Noise spectrum estimating section 104 estimates a noise spectrum based on the speech spectrum determined as the non-speech ...

System for noise suppression, transceiver and method for noise suppression

The Journal of the Acoustical Society of America, 2006
A system with an accompanying method is provided to improve the signal-to-noise ratio (SNR) of noisy speech by suppressing acoustic background noise. The background noise consists of narrow band noise from rotating machine, audio signals from stereo-loudspeakers of audio entertainment device, and other ambient noise.

Suppression and stabilisation of noise

International Journal of Control, 2009
In this article, we investigate the stochastic suppression and stabilisation of nonlinear systems. Given an unstable differential equation , in which f satisfies the one-sided polynomial growth condition, we introduce two Brownian noise feedbacks and therefore stochastically perturb this system into the nonlinear stochastic differential equation . This

Noise suppressing transmitter and noise suppressing method

The Journal of the Acoustical Society of America, 2000
Signals outputted from microphones 111 and 112 are inputted through filters 118 and 119 to noise suppressing sections A and B. One having smaller power is selected from output signals S107a and S107b by switching a selection switch SW in a signal power comparing section 117, to which the output signals S107a and S107b have been inputted, and a ...

Noise-Suppressing Deep Tracking

IEEE Transactions on Circuits and Systems for Video Technology, 2022
In visual tracking, it is challenging to distinguish the target from similar objects called noises in the background. As deep trackers use convolutional neural networks for image classification as feature extractors, the extracted features are insensitive to different instances in the same class, which is prone to make prediction models confuse the ...

Implementation for noise suppression in images

Image and Vision Computing, 1986
Abstract Random noise in images represents the primary problem for early visual processing. This paper describes an adaptive surface labelling technique (ASL) that suppresses image noise by using data-driven rules that concern surface continuity. The algorithm first obtains a global estimate of the noise distribution and then tries to fit a surface ...
