A Reverberation Chamber with Polycylindrical Walls [PDF]

The Journal of the Acoustical Society of America, 1951
A reinforced concrete reverberation chamber has been constructed with diffusing cylinders of random size cast in the ceiling and walls. Energy loss in the empty chamber is low because the rigid, heavily enameled walls have a low absorption coefficient and the attenuation loss in the air is moderate for such a small volume.

Consensus Formation and Change are Enhanced by Neutrality

Advanced Science, EarlyView.
Neutral agents are shown to enhance both the formation and overturning of consensus in collective decision‐making. A general mathematical model and experiments with locusts and humans reveal that neutrality enables robust consensus via simple interactions and accelerates consensus change by reducing effective population size.

Visual and acoustic performance of shading devices – real scale laboratory measurements [PDF]

E3S Web of Conferences, 2019
There are several physical parameters that are taken into consideration when determining the level of agreeability of an enclosed space. For instance, when choosing the louvers for a room there are a multitude of criteria that might be considered such as

Intravital Multimodal Imaging of Human Cortical Organoid Transplantation in a Mouse Model of Chronic Stroke

Advanced Science, EarlyView.
A multimodal intravital imaging platform enables longitudinal tracking of human cortical organoids transplanted into chronic stroke lesions. By combining surgical microscopy, MRI, bioluminescence imaging, and two‐photon fluorescence microscopy, the platform captures graft placement, viability dynamics, and cellular‐scale morphology in vivo, offering a ...

Two Alternative Methods to Measure the Radiated Emission in a Reverberation Chamber

International Journal of Antennas and Propagation, 2016
One of the most important applications of a reverberation chamber is for radiated power measurement. Two new alternative methods are proposed to measure the radiated power of equipment under test in a reverberation chamber in this paper.

Probability distributions of three‐antenna efficiency measurement in a reverberation chamber

IET Microwaves, Antennas & Propagation, 2021
Analytical expressions are derived for probability distributions of the three‐antenna efficiency measurement. The probability density function (PDF), the expected value, and the standard deviation are derived analytically. The Mellin transform is used in

TSPYL5 Promotes Triple‐Negative Breast Cancer Metastasis by Antagonizing USP10‐Mediated PTEN Stabilization to Unleash a ZEB1‐Dependent EMT Program

Advanced Science, EarlyView.
The hyperactivation of PI3K/AKT signaling in PTEN wild‐type triple‐negative breast cancer represents a clinical paradox. We delineate a novel post‐translational regulatory axis wherein the oncogene TSPYL5 competitively antagonizes the deubiquitinase USP10.

The Effect of Reverberation Time and Signal-to-Noise Ratio On Word Recognition Scores By Adults and Children in Classrooms

Megaron, 2019
This paper seeks to assess the effect of reverberation time, distribution of reverberation time over the frequency range and signal-to-noise ratio on speech intellibility by adults and children in classrooms by the use of phonetically balanced ...

Frequency characterization of reverberation chambers [PDF]

Proceedings of Symposium on Electromagnetic Compatibility, 2002
A series of measurements to investigate the modal structure of a reverberation chamber were conducted at the Dahlgren Division of the Naval Surface Warfare Center, Dahlgren, Virginia. These measurements were Phase I of a project to determine the frequency dependent characteristics of the fields in a reverberation chamber.

T2T Genome Assembly and Multi‐Omics Data Reveal Terrestrial Adaptation and Mucus Biosynthesis in Tropical Leatherleaf Slug (Laevicaulis alte)

Advanced Science, EarlyView.
A gap‐free genome assembly and multi‐omics comparison of the terrestrial slug Laevichaulis alte with an aquatic relative reveal that expansion of the VEGF family orchestrates mucus production, lipid metabolism, and immune defense—highlighting key molecular innovations for conquering life on land.
