Halide Perovskite: A Rich Source of Thermal Insulator
Advanced Science, EarlyView.Halide perovskites exhibit ultralow thermal conductivity driven by intrinsic lattice softness and strong anharmonicity, falling below conventional defect‐engineering limits. Weak metavalent bonding, A‐site rattling, and dynamic octahedral tilting drive phonon scattering to the Ioffe–Regel limit, where wave‐like tunneling replaces particle‐like ...

Molecular and Cellular Hallmarks of Age‐Related Vestibular Hair Cell Degeneration
Advanced Science, EarlyView.This study utilizes single‐cell RNA‐seq transcriptomes, advanced imaging, and electrophysiology to examine universal and cell‐type‐specific aging signatures of vestibular hair cells. The study shows that impaired hair bundle function is a key driver of age‐related vestibular dysfunction.

Analytical models for laterally flexible rocking bodies
Rocking motion often arises due to dynamic excitations, such as earthquakes. To understand the rocking behaviour of non-rigid structures, specifically laterally flexible rocking bodies, this thesis develops analytical models of flexible rocking ...

The Influence of Boundary Conditions on the Seismic Resistance of Retrofitted Ancient Masonry Towers
BuildingsHistoric masonry towers represent a significant part of the cultural heritage, which is often subject to retrofitting for preservation purposes. Due to the poor quality of the mortar, if present at all, the connection of existing towers to the foundation

Advanced Science, EarlyView.A minimally invasive optical window enables stable, long‐term imaging of peripheral nerves in vivo at single‐axon resolution. Dynamic processes of degeneration, regeneration, and cellular remodeling are visualized across multiple time scales within the same nerve region, providing a unique platform to study a variety of anatomical and molecular events ...

, 2013 The aim of this thesis is to improve the definition of vibrations ("seismic motion") on "hard" sites (hard soils or rocks) related to scenarios (earthquakes of magnitude between 5 and 6.5, distances less than 50 km) representative of the French metropolitan context.In order to constrain the seismic motions on "hard" sites, an accelerometric database ...

Impact of Randomized Soil Properties and Rock Motion Intensities on Ground Motion
Advances in Civil EngineeringSeismic site response is inevitably influenced by natural variability of soil properties and anticipated earthquake intensity. This study presents the influence of variability in shear wave velocity (Vs) and amplitude of input rock motion on seismic site response analysis.

A Multimodal Haptic Feedback Interface with Thin‐Film Compliant Mechanism
Advanced Science, EarlyView.Multimodal haptic devices can trigger different mechanoreceptors, enabling richer haptic information. This study presents an electromagnetic multimodal haptic device capable of delivering indentation, stretch, and vibration stimuli. The device is enabled by a novel polymer thin‐film compliant mechanism that provides high translational compliance along ...

Seismic overturning of damped rocking structures
, 2011 Numerous structures exhibit rocking behavior during earthquakes and there is a continuing need to retrofit these structures to prevent collapse. The behavior of stand-alone rocking structures has been thoroughly investigated, but there are relatively few
