Characterization of an Injectable Poly(vinyl alcohol)‐gelatin Hydrogel for Growth Factor Delivery in an Orthopedic Application

Advanced Healthcare Materials, EarlyView.
This work introduces photo‐crosslinkable tyraminated poly(vinyl alcohol)‐gelatin (PVA‐GT) hydrogels as tunable injectable platforms for tissue engineering and growth factor delivery applications. This schematic illustrates the two developed hydrogel formulations and the experimental workflow used to evaluate their physico‐chemical properties in vitro ...

Overview of three-phase inverter topologies for distributed generation purposes [PDF]

, 2010
The increasing presence of single-phase distributed generators and unbalanced loads in the electric power system may lead to unbalance of the three phase voltages, resulting in increased losses and heating.

Successive opening of the Fermi surface in doped N-leg Hubbard ladders

, 2000
We study the effect of doping away from half-filling in weakly (but finitely) interacting N-leg Hubbard ladders using renormalization group and bosonization techniques. For a small on-site repulsion U, the N-leg Hubbard ladders are equivalent to a N-band

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Control strategy of parallel three-phase four-leg inverter under unbalanced conditions

Dianzi Jishu Yingyong, 2019
A compound control strategy is proposed in order to solve the low control accuracy and poor anti-disturbance of deadbeat control. In this method, the repetitive control is embedded into the deadbeat control to improve the robustness of the control system

The association between social factors and body length proportions in Polish schoolchildren from Lower Silesia

Anthropological Review, 2016
Many studies worldwide have shown that social factors are significantly associated with growth in childhood. However, very few researchers studied influence of social factors on body length proportions. The aim of the present study was the assessment how

Biomechanical Analysis of Mongolian Bronze and Iron Age Four‐Legged Walking Petroglyphs

Natural Sciences
Since the works of Eadweard Muybridge in the 1880s, the characteristics of motion of four‐legged animals are well known for experts of animal locomotion, and the different gaits of many four‐legged species have been investigated in detail.
