Hierarchical fiber bundle strength statistics [PDF]

, 2012
Multi-scale modeling is currently one of the most active research topics in a wide range of disciplines. In this thesis we develop innovative hierarchical multi-scale models to analyze the probabilistic strength of fiber bundle structures.

Mechanical Programming of PEGDA‐β‐CD Polyrotaxane‐Based Hydrogels via Host–Guest Molecular Recognition

Advanced Functional Materials, EarlyView.
A mechanically programmable hydrogel for tissue engineering is developed by modulating the molecular threading density of poly(ethylene glycol) diacrylate‐β‐cyclodextrin (PEGDA‐β‐CD) polyrotaxane and combining it with β‐CD‐modified gelatin. The polyrotaxane‐guided transition from disordered pores to laminar microstructures enables precise tuning ...

Physiological readiness for harvest in machine-harvested cotton: Linking canopy regulation, maturity synchrony, diagnostic thresholds, and lint yield and quality realization

Industrial Crops and Products
Xinjiang has developed one of the world’s most advanced and productive machine-harvested cotton systems under arid irrigated conditions, yet the central challenge is no longer yield formation alone but the reliable conversion of pre-harvest productivity ...

Multistage, Self‐Sensing Artificial Muscles With Coordination From Liquid Crystal Elastomer‐Graphene Composite Fibers

Advanced Functional Materials, EarlyView.
Inspired by skeletal muscles’ precision and endurance, CoilLCE integrates a self‐sensing liquid crystal elastomer/graphene artificial muscle with an embedded Joule‐heating copper coil, enabling closed‐loop multistage actuation with programmable intermediate states (strain accuracy of 2%), and antagonistic coordination (32% total strain). These features

Assessing cotton maturity from fiber cross-section measurements [PDF]

, 2014
textThe previous Fiber Image Analysis System (FIAS-I) is not reliable enough to detect fibers, especially for the immature fibers. It yields a systematic bias in the maturity distribution.

In situ impacts of late‐season low temperatures on cotton (Gossypium hirsutum) fiber quality and yield on the Texas High Plains

Agrosystems, Geosciences & Environment
Upland cotton (Gossypium hirsutum) production is important for the economy of the Texas High Plains (THP). This region of Texas is semi‐arid and regularly experiences harsh weather conditions that can be difficult to predict.

2D Skeletal Muscle Thin Film Actuators Enhance Efficiency of Biohybrid Robots

Advanced Functional Materials, EarlyView.
2D skeletal muscle thin film actuators generate millinewton‐scale forces and millimeter‐scale strokes while remaining functional for over 30 days. Their force density is 20‐fold higher than 3D skeletal muscle actuators, enabling multi‐fin robots with tunable speed and multidirectional steering.

The At Issue Maturity of Corporate Bonds: The Influence of Credit Rating, Security Level, Duration and Macreoconomic Conditions [PDF]

We examine the determinants of the at issue time to maturity of corporate bonds. We find evidence that corporations partly determine the at issue maturity of bonds by responding to economic conditions.
