Needs for structural health monitoring in the last decades were rapidly increasing, and these needs stimulated developments of various sensing technologies. Distributed optical fiber sensing technologies have reached market maturity and opened new possibilities in structural health monitoring. Distributed strain sensor (sensing cable) is sensitive at each point of its length to strain changes a...

Monitoring of human bodily motion requires wearable sensors that can detect position, velocity and acceleration. They should be cheap, lightweight, mechanically compliant and display reasonable sensitivity at high strains and strain rates. No reported material has simultaneously demonstrated all the above requirements. Here we describe a simple method to infuse liquid-exfoliated graphene into n...

Surveillance of noroviruses in Italy identified the novel GII.17 human norovirus strain, Kawasaki 2014, in February 2015. This novel strain emerged as a major cause of gastroenteritis in Asia during 2014/15, replacing the pandemic GII.4 norovirus strain Sydney 2012, but being reported only sporadically elsewhere. This novel strain is undergoing fast diversification and continuous monitoring is ...

Mechanochromic strain sensors based on photonic crystals, which can change structural color upon mechanical deformation, are promising for many applications including health monitoring and damage detection. Here, a large-strain full-color crystal film as mechanochromic sensor is reported. The (MPC) with grating nanostructure achieved by fast low-cost inverted nanoimprint lithography. enables br...

Laboratory bioassays were conducted to determine the response of larvae of a susceptible strain of diamondback moth Plutella xylostella (L.) from the Rio Grande Valley of south Texas to five classes of insecticides. Test insecticides were permethrin, methamidophos, endosulfan, methomyl and Bacillus thuringiensis. Three monitoring techniques were developed and tested as methods of determining th...

Structural health monitoring is a critical requirement in many composites. Numerous monitoring strategies rely on measurements of temperature or strain (or both), however these are often restricted to point-sensing or to the coverage of small areas. Spatially-continuous data can be obtained with optical fiber sensors. In this work, we report high-resolution distributed Brillouin sensing over st...

conclusions pci was accompanied by some improvement in left atrial deformation indices as assessed by tissue doppler imaging. revascularization can, therefore, improve patient outcome. results regarding changes in left trial functional parameters after pci, those such as the strain of the septal wall and the anterior and inferior walls and the strain rate of the anterior and lateral walls signi...
