Optoelectrical Devices for Neural Interfacing: Engineering Integration, Stability, and Multimodal Sensing

Advanced Healthcare Materials, EarlyView.
Implantable optoelectrical devices are an effective resource for the modulation and monitoring of neural activity with high spatiotemporal resolution. This review discusses current challenges faced by these devices and outlines future perspectives for the development of next‐generation neural interfaces targeting chronic, multisite, and multimodal ...

ETV2 Mediated Differentiation of Human Pluripotent Stem Cells Results in Functional Endothelial Cells for Engineering Advanced Vascularized Microphysiological Models

Advanced Healthcare Materials, EarlyView.
A robust method to generate functional human iPSC‐derived endothelial cells using inducible ETV2 expression. These cells self‐organize into stable, lumenized microvascular networks within microfluidic chips, surpassing conventional differentiation methods.

Shear behavior of human skull bones

Journal of the Mechanical Behavior of Biomedical Materials, 2021
A shear-punch test (SPT) experimental method was developed to address the lack of shear deformation and failure response data for the human skull as a function of local bone microarchitecture. Improved understanding of skull deformation and fracture under varying stress-states helps implement mechanism-based, multi-axial material models for finite ...

Bolted shear connectors in steel–concrete composite structures: Shear behavior

Structures, 2023
The use of bolted shear connectors is of great importance to the sustainable development of steel–concrete composite structures. In this paper, an experimental program consisting of four push-out specimens is performed to investigate the effects of bolt length and fabrication method of concrete slabs on the shear behavior of single-nut embedded bolted ...

“Unexpected” shear‐wave behavior

GEOPHYSICS, 1997
In a previous study, we inverted shear‐wave birefringence observations from an azimuthal vertical seismic profile (VSP) experiment conducted at the Conoco Borehole Test Facility, Oklahoma (Horne and MacBeth, 1994; Horne, 1995). Our results indicate that the observations can be interpreted in terms of two distinctly different transversely isotropic (TI)

Shear Behavior of Bovine Scleral Tissue

Journal of Biomechanical Engineering, 2014
Ocular tissue properties have been widely studied in tension and compression for humans and a variety of animals. However, direct shear testing of the tissues of the sclera appear to be absent from the literature even though modeling, analyses, and anatomical studies have indicated that shear may play a role in the etiology of primary open angle ...

Shear-resistant behavior of light composite shear wall

Journal of Central South University, 2015
Shear test results for a composite wall panel in a light composite structure system are compared with test results for shear walls in Japan. The analysis results show that this kind of composite wall panel works very well, and can be regarded as a solid panel.

Modeling Shear Behavior in the Annulus Fibrosus

ASME 2008 Summer Bioengineering Conference, Parts A and B, 2008
An accurate constitutive law for the annulus fibrosus (AF) is critical to modeling the complex loads and deformations of the intervertebral disc. In the healthy disc, the loads applied to the AF are primarily a combination of tension and torsion. Several researchers [1–5] have developed nonlinear strain energy functions to model the AF using the fiber ...

Nonlinear fluid behavior: from shear thinning to shear thickening

Physica A: Statistical Mechanics and its Applications, 1994
Abstract A phenomenological model is introduced which describes both shear thinning and shear thickening behavior. Consequences of this model are presented for plane Couette (simple shear) flow. The non-Newtonian viscosity and normal pressure differences are discussed for a stationary situation.

Critical behavior of entropic shear rigidity

Physical Review E, 2006
We report on extensive molecular dynamics (MD) simulations of a model for gels in both two and three dimensions. The model consists of randomly cross-linked monomers with a concentration p of cross-links above the percolation concentration so that the system is in the amorphous solid phase. As the concentration of cross-links approaches the percolation
