Multifunctional Neural Probes Enable Bidirectional Electrical, Optical, and Chemical Recording and Stimulation In Vivo

Advanced Materials, EarlyView.
Convergence drawing is used to create flexible, microscale, multifunctional fiber‐based neural probes. Optimized materials selection enables individual devices to perform neural recording, electrical stimulation, optogenetics, fiber photometry, fluid delivery, and voltammetric neurotransmitter detection in rodents.

Multichannel Linear Prediction for Blind Reverberant Audio Source Separation [PDF]

arXiv, 2017
A class of methods based on multichannel linear prediction (MCLP) can achieve effective blind dereverberation of a source, when the source is observed with a microphone array. We propose an inventive use of MCLP as a pre-processing step for blind source separation with a microphone array.

Solvothermal Template‐Induced Hierarchical Porosity in Covalent Organic Frameworks: A Pathway to Enhanced Diffusivity

Advanced Materials, EarlyView.
Hierarchically porous covalent organic frameworks (hCOFs) are constructed using a solvothermal template‐induced synthetic strategy. Commercially available zinc oxide nanoparticles are employed as hard template enabling an increase in total pore volume in a series of COFs.

Approaches to the study of neural coding of sound source location and sound envelope in real environments.

Frontiers in Neural Circuits, 2012
The major functions of the auditory system are recognition (what is the sound) and localization (where is the sound). Although each of these has received considerable attention, rarely are they studied in combination.

FDTD modelling of reverberation chamber

Electronics Letters, 2005
The finite-difference time-domain (FDTD) method is applied to the simulation of a reverberation chamber. The real losses of the reverberation chamber are taken into account in a post-treatment process. The predicted results are compared with measured data and good agreement is reported.

Nanoscale Biodegradable Printing for Designed Tuneability of Vaccine Delivery Kinetics

Advanced Materials, EarlyView.
Spatiotemporal Controlled Release Inks of Biocompatible polyEsters (SCRIBE) is a novel 2PP resin family with sub‐micron resolution and tuneable hydrolysis. SCRIBE enables direct printing of hollow microparticles with complex chemistries and geometries inaccessible to molding techniques, which are used to modulate antibody titers and class switching as ...

SRMR variants for improved blind room acoustics characterization [PDF]

arXiv, 2015
Reverberation, especially in large rooms, severely degrades speech recognition performance and speech intelligibility. Since direct measurement of room characteristics is usually not possible, blind estimation of reverberation-related metrics such as the reverberation time (RT) and the direct-to-reverberant energy ratio (DRR) can be valuable ...

Upconversion Nanoparticle‐Covalent Organic Framework Core–shell Particles as Therapeutic Microrobots Trackable With Optoacoustic Imaging

Advanced Materials, EarlyView.
Upconversion nanoparticle‐covalent organic framework core–shell particles provide enhanced contrast for optoacoustic imaging by leveraging the optical absorption of upconversion luminescence within the covalent organic framework matrix. Beyond their role as contrast agents, these particles enable customizable therapeutic agent loading and release, as ...

Non-Exponential Reverberation Modeling Using Dark Velvet Noise [PDF]

arXiv
Previous research on late-reverberation modeling has mainly focused on exponentially decaying room impulse responses, whereas methods for accurately modeling non-exponential reverberation remain challenging. This paper extends the previously proposed basic dark-velvet-noise reverberation algorithm and proposes a parametrization scheme for modeling late

Highly-Reverberant Real Environment database: HRRE [PDF]

arXiv, 2018
Speech recognition in highly-reverberant real environments remains a major challenge. An evaluation dataset for this task is needed. This report describes the generation of the Highly-Reverberant Real Environment database (HRRE). This database contains 13.4 hours of data recorded in real reverberant environments and consists of 20 different testing ...
