Tunable Complementary Doping Strategy Enables High‐Performance Homo‐Channel CMOS in Monolayer WSe2
Advanced Functional Materials, EarlyView.Polarity‐selective modulation enables a homo‐channel WSe2 CMOS platform from a single 2D semiconductor. MoOx and AlN tune WSe2 toward p‐ and n‐type operation, respectively, yielding complementary FETs and inverters with balanced switching, high voltage gain, low static power, and promising scalability for 2D logic integration.

Nanodiamond Sensing in Dynamic Environments With Fast‐Tracking Through Four‐Point Positioning
Advanced Functional Materials, EarlyView.A four‐point positioning tracking (4PPT) platform enables fast 3D feedback translational tracking of fluorescent nanodiamonds while simultaneously recording ODMR spectra. By integrating real‐time translational tracking with quantum sensing, mobile nanodiamonds are used for in‐situ nanothermometry, nanorheometry, and 6D translation–rotation tracking in ...

Advanced Functional Materials, EarlyView.Low‐frequency noise spectroscopy defines the resolvable conductance states of synaptic FeFETs by coupling read‐current fluctuation with usable dynamic range. The resulting noise‐limited bit precision establishes a universal, device‐agnostic reliability metric beyond the memory window, enabling quantitative benchmarking and rational design of high ...

Journal of Aircraft, 1976
Experiments have been conducted on axisymmetric shallow cavity flows with the aim of investigating methods to modify cavity shear flows such that cavity noise may be reduced. The experiments indicate the presence of large gross lateral motion of the shear layer close to the downstream cavity corner which, on interaction with it, results in production ...

Active noise control exploits the long wavelengths associated with low frequency sound. It works on the principle of destructive interference between the sound fields generated by the original primary sound source and that due to other secondary sources, acoustic outputs of which can be controlled.

Active noise control systems for controlling outdoor environmental noise
1999 European Control Conference (ECC), 1999A unique theory for generating electronically controlled acoustic shadows for environmental noise reduction was reported in [1]. The theory has been extended to complex high frequency sound from large non-compact sources [2] and implemented into hardware [3]. These studies show that deep acoustic shadows are possible.

Active Shielding and Control of Noise
SIAM Journal on Applied Mathematics, 2001Summary: We present a mathematical framework for the active control of time-harmonic acoustic disturbances. Unlike many existing methodologies, our approach provides for the exact volumetric cancellation of unwanted noise in a given predetermined region of space while leaving unaltered those components of the total acoustic field that are deemed ...

So far we have dealt with sound sources that convert electric energy into mechanic/acoustic energy. These sound sources are mainly used to radiate desired sounds because the mechanic/acoustic signals are easily controlled by the electric ones. In addition to desired sound, there is undesired sound that one would reduce or even eliminate if possible ...
