Crossed Simplicial Group Categorical Nerves [PDF]

open access: yesarXiv, 2016
We extend the notion of the nerve of a category for a small class of crossed simplicial groups, explicitly describing them using generators and relations. We do this by first considering a generalised bar construction of a group before looking at twisted versions of some of these nerves.

Bioprinting Perfusable and Vascularized Skeletal Muscle Flaps for the Treatment of Volumetric Muscle Loss

open access: yesAdvanced Healthcare Materials, EarlyView.
Volumetric muscle loss (VML) due to trauma or surgery, often leads to physical impairments. Traditional treatments rely on autologous flaps, limited by muscle availability often leading to donor site morbidity. This study presents multimodal bioprinting as an innovative approach for fabricating vascularized muscle flaps with 3D‐printed macrovessels ...

Strongly Proximal Edelsbrunner-Harer Nerves in Voronoi Tessellations [PDF]

open access: yesarXiv, 2016
This paper introduces Edelsbrunner-Harer nerve in collections of Voronoi regions (called nucleus clusters) endowed with one or more proximity relations. The main results in this paper are that a maximal nucleus cluster (MNC) in a Voronoi Tessellation is a strongly proximal Edelsbrunner-Harer nerve, each MNC nerve and the union of the sets in the MNC ...

Motor‐Free Soft Robots for Cancer Detection, Surgery, and In Situ Bioprinting

open access: yesAdvanced Healthcare Materials, EarlyView.
Novel motor‐free soft robots for cancer detection, surgery, and in situ bioprinting–are presented. This master‐slave system is constructed from soft fibrous syringe architectures, removing the need for electrical motors and complex control mechanisms, while reducing the physical tremors.

Nerves of 2-categories and 2-categorification of $(\infty,2)$-categories [PDF]

open access: yesarXiv, 2019
We show that the homotopy theory of strict 2-categories embeds in that of $(\infty,2)$-categories in the form of 2-precomplicial sets. More precisely, we construct a nerve-categorification adjunction that is a Quillen pair between Lack's model structure for 2-categories and Riehl-Verity's model structure for 2-complicial sets. Furthermore, we show that

Lycium‐Barbarum Polysaccharide‐Loaded Dual‐Crosslinked Rigid Hydrogel Enhances Bone Healing in Diabetic Bone Defects by Scavenging Reactive Oxygen Species

open access: yesAdvanced Healthcare Materials, EarlyView.
A novel hydrogel (HLBP) incorporating natural polysaccharides from goji berries is developed to enhance diabetic bone defect healing. The hydrogel efficiently scavenges ROS, improves osteogenic differentiation, and promotes in vivo bone regeneration. This strategy offers a biocompatible and localized approach, overcoming the challenges of traditional ...

Vortex Nerves and their Proximities. Nerve Betti Numbers and Descriptive Proximity [PDF]

open access: yesBulletin of the Allahabad Mathematical Society vol. 34, no. 2, 2019, 263-276, 2019
This article introduces vortex nerve complexes in CW (Closure finite Weak) topological spaces, which first appeared in works by P. Alexandroff, H. Hopf and J.H.C. Whitehead during the 1930s. A vortex nerve is a CW complex containing one or more intersecting path-connected cycles. Each vortex nerve has its own distinctive shape. Both vortex nerve shapes
