Distributed shop floor control is likely to become a key component of 21st century manufacturing technology. The interest in distributed control arises from the promise of increased flexibility, reliability, and tolerance to the uncertainty that exists in the shop floor environment. However, the communicational complexities involved in the integration of(More)
BACKGROUND Peripheral nerve injury results in chronic neuropathic pain characterized by allodynia and/or spontaneous pain. It has been suggested that activation of mitogen-activated protein kinases such as extracellular signal-regulated kinase (ERK) and c-Jun N-terminal kinase (JNK) contribute to the neuropathic pain. OBJECTIVES We investigated if(More)

Parallel-plate capacitors were fabricated using a printed multi-layer structure in order to determine the effects of particle size and solvent on the capacitance. The conductive-dielectric-conductive layers were sequentially spun using commercial inks and by intermediate drying with the aid of a masking polymeric layer. Both optical and scanning electron(More)
Balloon whisk-like and flower-like SiOx tubes with well-dispersed Sn and joining countless SiOx loops together induce intense luminescence characteristics in substrate materials. Our synthetic technique called "direct substrate growth" is based on pre-contamination of the surroundings without the intended catalyst and source powders. The kind of supporting(More)
PURPOSE Opioid-based intravenous patient-controlled analgesia (IV-PCA) is a popular method of postoperative analgesia, but many patients suffer from PCA-related complications. We hypothesized that PCA was not essential in patients undergoing major abdominal surgery by minimal invasive approach. METHODS Between February 2013 and August 2013, 297 patients(More)
