The Time Integral Basic to Optimum Reverberation Time [PDF]

The Journal of the Acoustical Society of America, 1948
Equations showing the relation between the volume, V, of an auditorium and its optimum reverberation time, T0, were published independently by MacNair and Lifschitz. MacNair's equation was derived from the following basic assumptions: ∫ 0T1 (logρ)dt = a const., E = const., where ρ=instantaneous value of the energy density of sound during decay,T1=time ...

Magnetic Resonance Imaging‐Based Quantification of Endosomal Escape Using Iron Oxide Nanoparticle‐Loaded Lipid Nanoparticles

Advanced Healthcare Materials, EarlyView.
The therapeutic efficacy of lipid nanoparticle(LNP)‐based drugs depends on endosomal escape. However, few methods are available for quantifying the efficiency of endosomal escape in vivo. Herein, a novel method for quantifying the endosomal escape efficiency index using magnetic resonance imaging is introduced.

Simulation Study on Detection and Localization of a Moving Target Under Reverberation in Deep Water

Journal of Marine Science and Engineering
Deep-water reverberation caused by multiple reflections from the seafloor and sea surface can affect the performance of active sonars. To detect a moving target under reverberation conditions, a reverberation suppression method using multipath Doppler ...

Reverberation Time and Power Model in Indoor Wireless Scenarios [PDF]

Radioengineering, 2018
A novel, room-electromagnetics-theory-based model for reverberation time, path gain and Power Delay Profile (PDP) is proposed. Unlike the traditional models describing only the reflections, the new model takes not only reflections at boundaries, but also

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.

Water Reverberation Travel Time Analysis Acquired Using Multi-Depth Streamers

Terrestrial, Atmospheric and Oceanic Sciences, 2016
Ghost reflections and water reverberations are major and inevitable seismic noises in marine seismic exploration. More recently, new receiver deployment techniques at different sea depths for signal-to-noise ratio (SNR) enhancement are developing.
