To improve the characteristics of a diamond-like carbon （DLC） film, Ti-containing amorphous hydrogenated carbon thin films were deposited on sus304 stainless steel substrates by high-power plasma-sputtering with titanium metal as the solid plasma source in a mixed ArC2H2 atmosphere. The films were fabricated to obtain a multilayered structure of Ti/TiC/DLC gradient for improving adhesion and reducing residual stress. The effects of substrate bias and target-substrate distance on the films＇ properties were studied by glow discharge spectroscope, X-ray diffractometer, Raman spectroscope, nanoindenter, and a pin-on-disk tribometer. The results indicate that the films possess superior adhesive strength and toughness.

AIM： To describe characteristics of a poorly expandable （PE） common bile duct （CBD） with stones on en- doscopic retrograde cholangiography.METHODS： APE bile duct was characterized by a rigid and relatively narrowed distal CBD with retro- grade dilatation of the non-PE segment. Between 2003 and 2006, endoscopic retrograde cholangiography （ERC） images and chart reviews of 1213 patients with newly diagnosed CBD stones were obtained from the computer database of Therapeutic Endoscopic Centerin Chang Gung Memoria acteristic PE bile duct on Hospital. Patients with char ERC were identified from the database. Data of the patients as well as the safety and technical success of therapeutic ERC were collected and analyzed retrospectively.RESULTS： A total of 30 patients with CBD stones and characteristic PE segments were enrolled in this study. The median patient age was 45 years （range, 20 to 92 years）; 66.7% of the patients were men. The di ameters of the widest non-PE CBD segment, the PE segment, and the largest stone were 14.3 ± 4.9 mm, 5.8±1.6 mm, and 11.2±4.7 mm, respectively. The length of the PE segment was 39.7±15.4 mm （range, 12.3 mm to 70.9 mm）. To remove the CBD stone（s） completely, mechanical lithotripsy was required in 25 （83.3%） patients even though the stone size was not as large as were the difficult stones that have been described in the literature. The stone size and stone/ PE segment diameter ratio were associated with the need for lithotripsy. Post-ERC complications occurred in 4 cases： pancreatitis in 1, cholangitis in 2, and an im- pacted Dormia basket with cholangitis in 1. Two （6.7%） of the 28 patients developed recurrent CBD stones at follow-up （50±14 mo） and were successfully managed with therapeutic ERC.CONCLUSION： Patients with a PE duct frequently require mechanical lithotripsy for stones extraction, To retrieve stones successfully and avoid complications, these patients should be identified during ERC,

Line drawing is a style of image abstraction where the perceptual content of the image is conveyed using distinct straight or curved lines. However,extracting semantically salient lines is not trivial and mastered only by skilled artists. While many parametric filters have successfully extracted accurate and coherent lines, their results are sensitive to parameter choice and easily lead to either an excessive or insufficient number of lines. In this work, we present an interactive system to generate concise line abstractions of arbitrary images via a few user specified strokes. Specifically, the user simply has to provide a few intuitive strokes on the input images, including tracing roughly along edges and scribbling on the region of interest, through a sketching interface. The system then automatically extracts lines that are long,coherent and share similar textural structures to form a corresponding highly detailed line drawing. We have tested our system with a wide variety of images. Our experimental results show that our system outperforms state-of-the-art techniques in terms of quality and efficiency.

We propose and experimentally demonstrate a recorded 1-m bidirectional 20.231-Gbit/s tricolor R/G/B laser diode(LD) based visible-light communication(VLC) system supporting signal remodulation. In the signal remodulation system, an LD source is not needed at the client side. The client reuses the downstream signal sent from the central office(CO) and remodulates it to produce the upstream signal. As the LD sources are located at the CO, the laser wavelength and temperature managements at the cost-sensitive client side are not *** is the first demonstration, to our knowledge, of a >20 Gbit∕s data rate tricolor R/G/B VLC signal transmission supporting upstream remodulation.

Topical AA was applied to both patients at least one month before and after with a frequency of four times per day. After the surgery, both eyes improved best-corrected visual acuity(BCVA) and there was limited human corneal endothelial cell loss without signs of corneal endothelial decompensation, such as deteriorated BCVA or persistent corneal edema during the follow-up of at least two *** Perioperative administration of topical AA may be an alternative therapy to the triple procedure in patients expecting to undergo cataract surgery.

Objective: This study aims to evaluate the impact and potential prognostic roles of the pre- and post-treatment Glasgow prognostic score (GPS) and the change thereof in patients with advanced head and neck cancer undergoing concurrent chemoradiotherapy (CCRT). Methods: We collected GPS and clinicopathological data of 139 stage III, IVA, and IVB head and neck cancer patients who underwent CCRT between 2008 and 2011. Their GPSs pre- and post-CCRT and the change thereof were analyzed for correlations with recurrence and survival. Results: The GPS changed in 72 (51.8%) patients, with worse scores observed post-CCRT in 65 (90.3%) of the GPS changed patients. Patients in the improved GPS group showed a tendency toward better survival. From the multivariate analysis, the post-CCRT GPS level was an independent prognostic factor in addition to tumor stage. Conclusions: After CCRT, a high GPS was revealed to be an important predictor of survival for advanced head and neck cancer.
