Advanced Science, EarlyView.There is growing interest in understanding how classroom teaching works, but previous theories and studies leave a gap in the neurocognitive mechanisms involved in real classroom teaching. Here we show that during real classroom teaching, students' middle frontal cortex serves as a hub of a rapid cortical learning process, supporting their knowledge ...

Multichannel audio signal source separation based on an Interchannel Loudness Vector Sum [PDF]
arXiv, 2015 In this paper, a Blind Source Separation (BSS) algorithm for multichannel audio contents is proposed. Unlike common BSS algorithms targeting stereo audio contents or microphone array signals, our technique is targeted at multichannel audio such as 5.1 and 7.1ch audio.

Advanced Science, EarlyView.Micromagnetic stimulation (µMS) offers a precise method for neural inhibition, complementing existing neuromodulation techniques. Using an implantable micro‐coil device, µMS selectively suppresses cortical activity with high spatial resolution. It effectively counteracts micro‐electrode stimulation and reduces seizure amplitude, highlighting its ...

C Implementation & comparison of companding & silence audio compression techniques [PDF]
IJCSI, Volume 7, Issue 2, March 2010, 2010 Just about all the newest living room audio-video electronics and PC multimedia products being designed today will incorporate some form of compressed digitized-audio processing capability. Audio compression reduces the bit rate required to represent an analog audio signal while maintaining the perceived audio quality. Discarding inaudible data reduces

Endothelial PD‐1 Regulates Vascular Homeostasis and Oligodendrogenesis during Brain Development
Advanced Science, EarlyView.Vascular endothelial cells are fundamental for angiogenesis and brain development. This study reveals that endothelial programmed cell death 1 (PD‐1) is critical for cerebral angiogenesis and blood brain barrier (BBB) maturation. It also mediates interaction with oligodendrocyte precursor cells (OPCs), modulating OPCs differentiation and myelination ...

Flexible Representation and Manipulation of Audio Signals on Quantum Computers [PDF]
arXiv, 2017 By analyzing the numerical representation of amplitude values in audio signals and integrating the time component, a representation for audio signals on quantum computers, FRQA, is proposed. The FRQA representation is a normalized state that facilitates basic audio signal operations targeting these parameters. The preparation and retrieval for FRQA are

Piezoresistive Effect: A New Concept for Hearing Aids
Advanced Science, EarlyView.An MXene/PVA sound sensor utilizing piezoresistive effects has been proposed with a detection limit of 60 dB and a frequency response of 20–4000 Hz, which is comparable to the performance of commercial hearing aids. By combining the sensor with machine learning, the accuracy rate of voiceprint recognition of wildlife conservation can reach up to 99 ...

Advanced Science, EarlyView.A simple to multiscale structure transition happens when a commercial porous foam is filled with multiwall carbon nanotubes with high aspect ratio. For an acoustic absorber with a porous material, the loading of multiwall carbon nanotubes can significantly improve its specific surface area while preserving its thickness and high porosity, thus enables ...

Reduced social attention in autism is magnified by perceptual load in naturalistic environments
Autism Research, Volume 15, Issue 12, Page 2310-2323, December 2022., 2022 Abstract Individuals with autism spectrum conditions (ASC) describe differences in both social cognition and sensory processing, but little is known about the causal relationship between these disparate functional domains. In the present study, we sought to understand how a core characteristic of autism—reduced social attention—is impacted by the ...
