Over the past decade, free-air CO2 enrichment (FACE) experiments have been conducted on several agricultural crops: wheat(Triticum aestivum L.), perennial ryegrass (Lolium perenne), and rice(Oryza sativa L.) which are C3 grasses; sorghum (Sorghum bicolor (L.) Möench), a C4 grass; white clover (Trifolium repens), a C3 legume; potato (Solanum tuberosum L.), a(More)
The extent to which terrestrial ecosystems can sequester carbon to mitigate climate change is a matter of debate. The stimulation of arbuscular mycorrhizal fungi (AMF) by elevated atmospheric carbon dioxide (CO(2)) has been assumed to be a major mechanism facilitating soil carbon sequestration by increasing carbon inputs to soil and by protecting organic(More)
Modern field-programmable gate arrays (FPGAs) have multimillions of gates and future generations of FPGAs will be even more complex. This means that floorplanning tools will soon be extremely important for the physical design of FPGAs. Due to the heterogeneous logic and routing resources of an FPGA, FPGA floorplanning is very different from the traditional(More)
The Raven-II is a platform for collaborative research on advances in surgical robotics. Seven universities have begun research using this platform. The Raven-II system has two 3-DOF spherical positioning mechanisms capable of attaching interchangeable four DOF instruments. The Raven-II software is based on open standards such as Linux and ROS to maximally(More)
OBJECTIVES Calcium and phosphate ion-releasing resin composites are promising for remineralization. However, there has been no report on incorporating antibacterial agents to these composites. The objective of this study was to develop antibacterial and mechanically strong nanocomposites incorporating a quaternary ammonium dimethacrylate (QADM),(More)
Allergic rhinitis (AR) and asthma represent global health problems for all age groups. Asthma and rhinitis frequently coexist in the same subjects. Allergic Rhinitis and its Impact on Asthma (ARIA) was initiated during a World Health Organization workshop in 1999 (published in 2001). ARIA has reclassified AR as mild/moderate-severe and(More)
BACKGROUND The current standard of care for cervical myopathy is anterior discectomy and fusion (ACDF). Although well tolerated in the short term, this treatment might ultimately result in progressive degeneration of adjacent motion segments. Artificial disc arthroplasty offers the theoretical advantage of preservation of motion at the operative level with(More)
Input vector control (IVC) technique is based on the observation that the leakage current in a CMOS logic gate depends on the gate input state, and a good input vector is able to minimize the leakage when the circuit is in the sleep mode. The gate replacement technique is a very effective method to further reduce the leakage current. In this paper, we(More)
In this prospective study, our aim was to compare the functional results and radiographic outcomes of fusion and Bryan Cervical Disc replacement in the treatment of two-level cervical disc disease. A total of 65 patients with two-level cervical disc disease were randomly assigned to two groups, those operated on with Bryan Cervical Disc replacement (31) and(More)
OBJECTIVE In recent years, a growing body of evidence has been reported that a tumor clone is organized as a hierarchy that originates from rare stem cells. CD133, a cell surface antigen, was identified as a stem cell maker for human leukemia, brain tumors, and prostate cancer. The purpose of this study was to detect the expression of CD133, a putative(More)
