They concluded that, 40% of patients had defective cQTD recovery at six months after the procedure and this was associated with increased late mortality risk. We would like to cont...

We use an instrument combining optical (surface plasmon resonance) and acoustic (Love mode acoustic wave device) real-time measurements on a same surface for the identification of water content in collagen and fibrinogen protein layers. After calibration of the surface acoustic wave device sensitivity by copper electrodeposition, the bound mass and its physical properties – density and optical ...

Mobile computing device adoption in organizations is proliferating with the rapid development of mobile computing technology. In this paper, we proposed a new construct, the Information Processing Support Index (IPSI), to capture how well these devices support employees’ job-required information processing activities. The instrument yields scores that measure perceptions about mobile devices’ c...
