Axisymmetric Scattering of p Modes by Thin Magnetic Tubes [PDF]
, 2011 We examine the scattering of acoustic p-mode waves from a thin magnetic fibril embedded in a gravitationally stratified atmosphere. The scattering is mediated through the excitation of slow sausage waves on the magnetic tube, and only the scattering of the monopole component of the wavefield is considered.

Conformally Perforated Shellular Metamaterials with Tunable Thermomechanical and Acoustic Properties
Advanced Functional Materials, EarlyView.This study introduces Conformally Perforated Shellular Metamaterials (CPSMs), which overcome TPMS design limitations by mapping 2D cellular layouts onto 3D surfaces. CPSMs exhibit enhanced elastic stiffness, thermal conductivity, and acoustic performance compared to intact P‐type shellulars, demonstrating their potential as multifunctional ...

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 finite element for viscothermal wave propagation [PDF]
, 2008 The well known wave equation describes isentropic wave propagation. In this equation, non-isentropic\ud boundary layer effects are neglected. This is allowed if the characteristic dimensions of the acoustic domain\ud are large with respect to the ...

Tattoo Assisted Optical Sensor System for Multimodal Discrete Physiological Sensing
Advanced Healthcare Materials, EarlyView.Conventional temporary tattoos can be used for improving the speckle imaging signal‐to‐noise ratio and stability of the specifically developed device for capturing skin motion related to physiological activities beneath the skin. This allows for sensing multimodal electrophysiological signals and physiological events from the skin consistent with ...
