Transmission of Vibration into Vibration-Isolated Buildings

Journal of Low Frequency Noise, Vibration and Active Control, 1991
Buildings constructed above or near underground and surface roads and railways often include some type of vibration isolation in their foundations. The effectiveness of such isolation measures is usually calculated by treating the building as a rigid block and the resulting mass-spring-damper system as a single-degree-of-freedom oscillator whose ...

Multiecho Fat‐Water Spiral MR Elastography With Distributed Encoding for Simultaneously Imaging Brain and Skull Displacement

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1617-1628, October 2026.
ABSTRACT Purpose To introduce a novel multiecho, multishot spiral MR elastography (MRE) sequence to image brain and skull displacement simultaneously using a joint fat‐water image reconstruction and distributed motion encoding. Methods Multiple echo times were implemented into a high‐resolution multishot spiral MRE sequence to capture water‐based brain

Bioactive Gold Plasmonic Interfaces Meet Artificial Intelligence: Advancing Saliva‐Based Surface‐Enhanced Raman Spectroscopy Diagnostics

Small, Volume 22, Issue 59, 22 October 2026.
ABSTRACT Bioactive gold plasmonic nanostructures are enabling non‐invasive saliva diagnostics by amplifying weak Raman signals and converting complex biofluid chemistry into information‐rich spectral fingerprints. This Review examines saliva‐based Raman and surface‐enhanced Raman spectroscopy (SERS) integrated with artificial intelligence (AI) from a ...

Measurement and modelling of seating dynamics to predict seat transmissibility

, 2014
The transmissibility of a seat depends on the dynamics of both the seat and the human body. Previous studies show that the apparent mass of the body, to which much attention has been paid, has a large influence on the vibration transmissibility of a seat.

Transmission of vertical vibration through a seat cushion at the seat pan: Effect of foam physical properties during different excitation magnitudes

Journal of Low Frequency Noise, Vibration and Active Control
The vibration characteristics of car seats directly influence the ride comfort. Polyurethane foam is the key part of a seat, and its physical parameters have an important impact on the seat.

Sequence‐encoded determinants drive distinct early aggregation pathways and different structural outcomes in PNT1 fibrils across Henipavirus members

Protein Science, Volume 35, Issue 9, September 2026.
Abstract Protein aggregation is increasingly recognized as a biologically relevant process in viral proteins, yet the molecular determinants governing such phenomena remain poorly understood. Intrinsically disordered proteins (IDPs) are ubiquitous in viral proteomes, where conformational plasticity not only enables functional diversity but also permits

Vibration control using vibration energy transmissibility of two-degree-of-freedom system with a coupling damper

Mechanical Engineering Journal
Frequency-averaged energy transmissibility and energy dissipation are formulated for a 2-DOF vibration system with both a coupling spring and a coupling damper, and their usefulness for vibration control design is discussed.

Power Flow in a Two-Stage Nonlinear Vibration Isolation System with High-Static-Low-Dynamic Stiffness

Shock and Vibration, 2018
The manuscript concerns the power flow characterization in a two-stage nonlinear vibration isolator comprising three springs, which are configured so that each stage of the system has a high-static-low-dynamic stiffness. To demonstrate the distinction of

Self‐Driven Hybrid Piezomagnetic–Iontronic Mechanoreceptors for Bimodal SA/RA Perception and Tactile Synthesis

Small, Volume 22, Issue 53, 21 September 2026.
A bimodal mechanoreceptor, integrating a piezomagnetic elastomer and an ion gel, simultaneously and independently transduces external mechanical stimuli into independent slow‐adapting signals for static pressure and rapid‐adapting signals for dynamic vibration.
