OBJECTIVE To describe an optimized surgical technique for feline vitrectomy which reduces bleeding and aids posterior gel clearance in order to facilitate stem cell delivery to the inner retina using cellular scaffolds. PROCEDURES Three-port pars plana vitrectomies were performed in six-specific pathogen-free domestic cats using an optimized surgical technique to improve access and minimize s...

A simple algorithm is presented for evaluating scattering parameters of a two-port network. This technique uses the indefinite admittance matrix to calculate scattering or any other desired set of two-port parameters.

This paper presents a new structure for a six-port reflectometer which due to its simplicity can be implemented very easily in monolithic microwave integrated-circuit (MMIC) technology. It uses nonmatched diode detectors with a high input impedance which are placed around a phase shifter in conjunction with a power divider for the reference detector. The circuit has been fabricated using the F2...

In this paper, the nonlinear cross-modulation noiser interference arising from channel filtering and leakage in a six-port digital ( ) millimetric receï er DMR is studied in detail. The in-band noiser interference arises from strong noiserinterference outside the receï ing ( ) bandwidth, and will deteriorate the bit-error rate BER . Analysis and simulation results of this effect are pro ̈ided, a...

Port organizations have focused their efforts on physical or tangible assets, generating profitability and value. However, it is recognized that the greatest sustainable competitive advantage is the creation of knowledge using the intangible assets of the organization. The Balanced ScoreCard, as a performance tool, has incorporated intangible assets such as intellectual, structural and social c...

MCC is a rare aggressive skin cancer with high(∼20%) risk of local recurrence. Postoperative radiotherapy(PORT) significantly improves control in early-stage and typically indicated if baseline factor(s) are present (positive/narrow surgical margins, primary tumor >1cm, head/neck (HN) location, immunosuppression (IMS), lymphovascular invasion(LVI)). However, conventionally fractionated PORT (C-...

PURPOSE Evaluation of the efficacy of single-shot, low-dose urokinase administration for the treatment of port catheter-associated fibrin sheaths. METHODS Forty-six patients were retrospectively evaluated for 54 episodes of port catheter dysfunction. The presence of a fibrin sheath was detected by angiographic contrast examinations. On an outpatient basis, patients subsequently received throm...

There are many accidents and risks occurred in many activities of operational systems at exclusive container terminals (ECTs) of Kaohsiung port in Taiwan. The container operators nowadays are facing great competitions on how reducing risks to manage those operational systems and activities at Kaohsiung port. Hence, the main purpose of this paper is to apply the fuzzy analytic hierarchy process ...
