Stimulated low-frequency Raman scattering in albumin [PDF]
Journal of Russian Laser Research, Volume 40, Number 1, January,
2019, 2019 Stimulated low-frequency Raman scattering can give essential information about the elastic properties of different nanoparticles systems, in particular, biological nanostructures. In the present study, low-frequency vibrational modes in human and bovine serum albumin were for the first time investigated using stimulated low-frequency Raman scattering ...

Advanced Functional Materials, EarlyView.The dynamic polarization reversal of coexisting normal and relaxor ferroelectrics in 1D TMAPbI₃ (tetramethylammonium, TMA) is deciphered through combined experimental and theoretical approaches. By bridging atomic‐scale motion, macroscopic polarization switching, and depolarization effects, a universal methodology is established to engineer next ...

Surface acoustic wave stimulated Brillouin scattering in thin-film lithium niobate waveguides [PDF]
arXiv, 2023 We report the first-ever experimental observation of backward stimulated Brillouin scattering (SBS) in thin-film lithium niobate (TFLN) waveguides. The peak Brillouin gain coefficient of the z-cut LN waveguide with a crystal rotation angle of 20$^{\circ}$ is as high as 84.9m$^{-1}$W$^{-1}$, facilitated by surface acoustic waves (SAW) at 8.06GHz.

Advanced Functional Materials, EarlyView.A visible light‐responsive polyacrylamide‐azobenzene hydrogel enables safe, reversible stiffness control for studying cell mechanobiology without harmful UV exposure. This approach reveals stem cells respond rapidly to mechanical changes, showing altered shape and protein distribution within one hour.

Autostabilisation de la phase acoustique dans un miroir Brillouin invers{é} en pr{é}sence d'une forte dispersion acoustique [PDF]
arXiv, 2022 We consider a counter-intuitive regime of stimulated Brillouin scattering in which the pump wave absorbs the phase defects of the Stokes wave, yielding a nonlinear self-stabilisation of the acoustic wave and a narrowing of the acoustic ...

Electric and Acoustic Stimulation in Cochlear Implant Recipients with Hearing Preservation
Seminars in Hearing, 2018 Hearing loss affects 30 million people in the United States, and a subset of these patients have normal low-frequency hearing and ski-sloped high-frequency hearing loss. For these patients, hearing aids alone may not provide adequate benefit.

TLR Agonist Nano Immune Therapy Clears Peritoneal and Systemic Ovarian Cancer
Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.Intraperitoneal administration of immunogenic Toll‐like receptor agonist‐modified mesoporous silica nanoparticles leads to rapid internalization by ascites myeloid cells with trafficking to fat‐associated lymphoid clusters. Activation of myeloid cells counters suppressive immune mechanisms associated with peritoneal metastasis, leading to regional and ...

A Computational Model of the Electrically or Acoustically Evoked Compound Action Potential in Cochlear Implant Users with Residual Hearing [PDF]
Objective: In cochlear implant users with residual acoustic hearing, compound action potentials (CAPs) can be evoked by acoustic (aCAP) or electric (eCAP) stimulation and recorded through the electrodes of the implant. We propose a novel computational model to simulate aCAPs and eCAPs in humans, considering the interaction between combined electric ...

Relationship between hearing function and myasthenia gravis: a contemporary review [PDF]
, 2016 There is increasing evidence of a connection between hearing function and myasthenia gravis (MG). Studies of the pathophysiological basis of this relationship suggest that acetylcholine receptors (AChRs) on outer hair cells (OHCs) play a central role. In
