Volume staging for arteriovenous malformation SRS treatment using VMAT
Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022 Abstract Volume staging involves dividing the target volume into smaller parts and treating each part separately. In this study, the feasibility of volume‐staged stereotactic radiosurgery (VS‐SRS) on a linear accelerator using volumetric modulated arc therapy (VMAT) and a frameless patient positioning system is investigated.

Effects of reverberation on speech intelligibility in noise for hearing-impaired listeners
Royal Society Open Science, 2022 Reverberation can have a strong detrimental effect on speech intelligibility in noise. Two main monaural effects were studied here: the temporal smearing of the target speech, which makes the speech less understandable, and the temporal smearing of the ...

A Space-Time Adaptive Processing Method Based on Sparse Reconstruction of Reverberation Interference
Xibei Gongye Daxue Xuebao, 2020 Aiming at the problem of how to obtain reverberation samples and estimate their covariance matrix in the space-time adaptive processing(STAP) of sonar system, a new space-time adaptive processing method is proposed based on sparse reconstruction of ...

X-ray reverberation around accreting black holes [PDF]
, 2014 Luminous accreting stellar mass and supermassive black holes produce power-law continuum X-ray emission from a compact central corona. Reverberation time lags occur due to light travel time-delays between changes in the direct coronal emission and ...

Cortical Sensorimotor Reverberations [PDF]
Neuron, 2015 In this issue of Neuron, Manita et al. (2015) report that reciprocal excitatory interactions between higher-order frontal motor cortex and primary sensorimotor cortex might play a key role in hindlimb sensory perception in mice.

Metasurfaced Reverberation Chamber [PDF]
Scientific Reports, 2018 AbstractThe concept of metasurfaced reverberation chamber (RC) is introduced in this paper. It is shown that by coating the chamber wall with a rotating 1-bit random coding metasurface, it is possible to enlarge the test zone of the RC while maintaining the field uniformity as good as that in a traditional RC with mechanical stirrers.

The anterior nucleus of the thalamus plays a role in the epileptic network
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 2010-2024, December 2022., 2022 Abstract Objectives We investigated both the metabolic differences and interictal/ictal discharges of the anterior nucleus of the thalamus (ANT) in patients with epilepsy to clarify the relationship between the ANT and the epileptic network. Methods Nineteen patients with drug‐resistant epilepsy who underwent stereoelectroencephalography were studied ...

Simulation of sonar reverberation signal considering the ocean multipath and Doppler effect
Frontiers in Marine Science, 2023 In order to achieve accurate modeling and simulation of sonar reverberation signals, four types of multi-path underwater reverberation models are established considering Doppler effect under the condition of separating the sound source and hydrophone ...
