Probability Distribution of the Quality Factor of a Mode-Stirred Reverberation Chamber
, 2012 We derive a probability distribution, confidence intervals and statistics of the quality (Q) factor of an arbitrarily shaped mode-stirred reverberation chamber, based on ensemble distributions of the idealized random cavity field with assumed perfect ...

Acoustical Modeling of Reverberation Chambers [PDF]
The Journal of the Acoustical Society of America, 1970 Critical listening tests conducted in full-scale reverberation chambers utilized in the recording industry reveal that there are often two major faults present in the decay of sound in the frequency range below 1000 Hz: (1) prolonged decay of certain axial modes resulting in a characteristic tone imparted to program materials; (2) beating between the ...

Ultrasmall Platinum Nanoparticles for Radiation‐Enhanced Cancer Therapy
Advanced Functional Materials, EarlyView.This work proposes a nanomedicine‐based strategy to enhance X‐ray radiotherapy for cancer treatment. Ultrasmall Pt‐NPs exhibit catalase‐like activity that may contribute to modulation of the tumor microenvironment and amplify interactions between radiation and biological matter, leading to increased DNA damage.

Advanced Healthcare Materials, EarlyView.Pressure skin wounds are frequent complications after spinal cord injury (SCI), with impaired healing due to vascular and immune deficits. Elastin‐like polypeptides (ELP) fused to α‐MSH (MSH‐ELP) or MCP‐1 (MCP‐ELP) are developed and tested on these wounds. The resulting nanoparticles are non‐toxic and bioactive, and they enhance macrophage recruitment,
