The effect of fatty infiltration, revision surgery, and sex on lumbar multifidus passive mechanical properties

open access: yesJOR Spine, 2023
Purpose Previous research has demonstrated increased stiffness in the multifidus muscle compared to other paraspinal muscles at the fiber bundle level. We aimed to compare single fiber and fiber bundle passive mechanical properties of multifidus muscle: (

Microstructure, bending and shear properties of 2.5D shallow cross-linked Cf/Al composites

open access: yesCailiao gongcheng, 2020
2.5D shallow cross-linked Cf/Al composites with volume fraction of 50% were fabricated by vacuum pressure infiltration. The microstructure, bending and shear properties at room and high temperature were studied. The failure mechanism of bending and shear

Adaptive Wave-Front Shaping and Beam Focusing through Fiber Bundles for High-Resolution Bioimaging

open access: yesPhotonics, 2021
We demonstrate an adaptive wave-front shaping of optical beams transmitted through fiber bundles as a powerful resource for multisite, high-resolution bioimaging.

Cracks in random brittle solids: From fiber bundles to continuum mechanics [PDF]

open access: yes, 2014
Statistical models are essential to get a better understanding of the role of disorder in brittle disordered solids. Fiber bundle models play a special role as a paradigm, with a very good balance of simplicity and non-trivial effects.

Cosmology of Lorentz fiber-bundle induced scalar-tensor theories [PDF]

open access: yesPhysical Review D, 2019
We investigate the cosmological applications of scalar-tensor theories that arise effectively from the Lorentz fiber bundle of a Finsler-like geometry.

Hirzebruch $\chi_y$-genera modulo $8$ of fiber bundles for odd integers $y$ [PDF]

open access: yes, 2016
I. Hambleton, A. Korzeniewski and A. Ranicki have proved that the signature of a fiber bundle F↪E→B of closed, connected, compatibly oriented PL manifolds is always multiplicative mod4, i.e. σ(E)≡σ(F)σ(B)mod4. In this paper, we consider the Hirzebruch χy-

Algebraic fiber bundles [PDF]

open access: yesTransactions of the American Mathematical Society, 1981
When X X is a finite simplicial complex and G G is any of a certain class of groups, a classification of G G -principal bundles over X X in terms of projective modules over a ring R ( G , X ) R(G,X) is given.
