A stochastic approach, the Ising model combined with Monte Carlo simulation, is employed to study the process of a fiber debonding and being pulled out from a fiber reinforced composite. The complicated mechanisms involved can be realistically simulated more than ever with a simple algorithm that is applicable to such phenomena as partial debonding, fiber breaking and matrix yielding, all of wh...

We propose a simplified definition of Quillen’s fibration sequences in pointed model category that fully captures the theory, although it is completely independent concept action. This advantage arises from understanding homotopy

We review the introduction of the space dimension into fiber-based technologies to implement compact and versatile signal processing solutions for microwave and millimeter wave signals. Built upon multicore fiber links and devices, this approach allows the realization of fiber-distributed signal processing in the context of fiber-wireless communications, providing both radiofrequency access dis...

Optical stimulation and silencing of neural activity is a powerful technique for elucidating the structure and function of neural circuitry. In most in vivo optogenetic experiments, light is delivered into the brain through a single optical fiber. However, this approach limits illumination to a fixed volume of the brain. Here a focused ion beam is used to pattern multiple light windows on a tap...

We present and evaluate a bilateral filter for smoothing diffusion MRI fiber orientations with preservation of anatomical boundaries and support for multiple fibers per voxel. Two challenges in the process are the geometric structure of fiber orientations and the combinatorial problem of matching multiple fibers across voxels. To address these issues, we define distances and local estimators of...
