205 Background: Indwelling pleural catheter (IPC) placement is an alternative to chemical pleurodesis for malignant pleural effusion (MPE), a complication of advanced cancer. In 1997 an IPC was approved which uses vacuum bottles (VB) for drainage (PleurX, Becton, Dickinson and Company, Franklin Lakes, NJ), and later another IPC system, which employs a manually operated vacuum pump (VP) for drainage (Aspira, Bard Access Systems, Salt Lake City, UT). Most studies comparing IPC versus chemical pleurodesis used the VB IPC...

BACKGROUND: Although vertical banded gastroplasty (VBG) is no longer performed in the USA, due to its popularity in 1980s, many patients still possess this anatomy with its inherent complications. The stomal stenosis secondary to tight ring or mesh is traditionally treated with surgical removal of the silastic ring or a complex revision, which was hampered by complications, technical complexity, and invasiveness. We described our experience of endoscopic management of this complex problem and the early outcomes...

G B Ingersoll, J R Leger
Recent research has shown that using multiple diverse-bandgap photovoltaic (PV) cells in conjunction with a spectrum splitting optical system can significantly improve PV power generation efficiency. Although volume Bragg gratings (VBGs) can serve as effective spectrum splitters, the inherent dispersion of a VBG can be detrimental given a broad-spectrum input. The performance of a single holographic spectrum splitter element can be improved by utilizing multiple single volume gratings, each operating in a slightly different spectral band...

BACKGROUND: Obesity is an epidemic on the rise. Increasing body mass index (BMI) has been associated with a number of comorbid diseases, including rarely reported motility disorders such as achalasia. Motility disorders are prevalent in obese patients, possibly more prevalent when compared to the nonobese population. Identification of motility disorders is important before bariatric surgery and may alter the planned type of procedure performed. Limited data exist regarding the development or existence of esophageal motility disorders after bariatric surgery...

We report a systematic study on the correlation of the electrical transport properties with the crystal phase and orientation of single-crystal InAs nanowires (NWs) grown by molecular-beam epitaxy. A new method is developed to allow the same InAs NW to be used for both the electrical measurements and transmission electron microscopy characterization. We find both the crystal phase, wurtzite (WZ) or zinc-blende (ZB), and the orientation of the InAs NWs remarkably affect the electronic properties of the field-effect transistors based on these NWs, such as the threshold voltage (VT), ON-OFF ratio, subthreshold swing (SS) and effective barrier height at the off-state (ΦOFF)...

The quest for materials showing large thermoelectric power has long been one of the important subjects in material science and technology. Such materials have great potential for thermoelectric cooling and also high figure of merit ZT thermoelectric applications. We have fabricated bilayer graphene devices with ionic-liquid gating in order to tune its band gap via application of a perpendicular electric field on a bilayer graphene. By keeping the Fermi level at charge neutral point during the cool-down, we found that the charge puddles effect can be greatly reduced and thus largely improve the transport properties at low T in graphene-based devices using ionic liquid gating...
