In a recent book (The Metaphysics within Physics), Tim Maudlin reconstructs metaphysics by taking inspiration from the gauge theories interpreted in the fiber bundle framework. I call his project the “fiber bundle metaphysics”. Primarily targeted not to Humean Supervenience, but to any metaphysics employing the relation of resemblance among objects (D. Lewis, D. Armstrong), Maudlin’s project is...

Consider a fiber bundle in which the total space, the base space and the fiber are all symplectic manifolds. We study the relations between the quantization of these spaces. In particular, we discuss the geometric quantization of a vector bundle, as oppose to a line bundle, over the base space that recovers the standard geometric quantization of the total space.

BACKGROUND The knowledge of in vivo anterior cruciate ligament (ACL) deformation is fundamental for understanding ACL injury mechanisms and for improving surgical reconstruction of the injured ACL. This study investigated the relative elongation of the ACL when the knee is subject to no load (<10 N) and then to full body weight (axial tibial load) at various flexion angles using a combined dual...

During the last decade, diffusion tensor imaging (DTI) has been used extensively to investigate microstructural properties of white matter fiber pathways. In many of these DTI-based studies, fiber tractography has been used to infer relationships between bundle-specific mean DTI metrics and measures-of-interest (e.g., when studying diffusion changes related to age, cognitive performance, etc.) ...

It is shown that a strong system of vector fields on a fiber bundle in the sense of [Mo] is induced from a principal fiber bundle if and only if each vertical vector field of the system is complete.

In this paper, we propose three metrics to quantify the differences between the results of diffusion tensor magnetic resonance imaging (DT-MRI) fiber tracking algorithms: the area between corresponding fibers of each bundle, the Earth Mover’s Distance (EMD) between two fiber bundle volumes, and the current distance between two fiber bundle volumes. We also discuss an interactive fiber track com...

ID No: FC-169 ABSTRACT The continuous fiber reinforced self-healing ceramic composites (shFRC) were proposed as one of the candidate materials for turbine blade [1]. The shFRC consists of three components, which are oxide fiber bundle, oxide matrix and self-healing agent interlayer. As the self-healing is generated at only the interlayer, it is necessary that crack propagation is led into the i...

Our group is currently developing an intravenous respiratory assist device that uses a centrally located pulsatile balloon within a hollow fiber bundle to enhance gas exchange rate via active mixing mechanism. We tested the hypothesis that the non-symmetric inflation and deflation of the balloon lead to both nonuniform balloon-generated secondary flow and nonuniform gas exchange rate in the fib...

In this article a typical near field output power distribution of an optical fiber is obtained with conventional cross sectional imaging of the fiber output beam and is used to predict the overlapped output beam of a fiber bundle. The proposed fiber bundle is a design system for power delivery of a light source to the target, specifically for medical applications. A Gaussian surface is generate...

The present work involves the development of a particle imaging velocimetry system using an optical fiber bundle scope as shown in Figure 1. Applying a fiber scope to PIV system, the resolution of particle images is spatially poorer than those taken directly by a CCD camera, which leads to an inadequate result of cross-correlation between a pair of particle images from the fiber scope. With a c...
