Abstract

The voltage, current, temperature, humidity, pressure, flow, and hydrogen in the high-pressure proton exchange membrane water electrolyzer (PEMWE) can influence its performance and life. For example, if the temperature is too low to reach the working temperature of the membrane electrode assembly (MEA), the performance of the high-pressure PEMWE cannot be enhanced. However, if the temperature is too high, the MEA may be damaged. In this study, the micro-electro-mechanical systems (MEMS) technology was used to innovate and develop a high-pressure-resistant flexible seven-in-one (voltage, current, temperature, humidity, pressure, flow, and hydrogen) microsensor. It was embedded in the upstream, midstream, and downstream of the anode and cathode of the high-pressure PEMWE and the MEA for the real-time microscopic monitoring of internal data. The aging or damage of the high-pressure PEMWE was observed through the changes in the voltage, current, humidity, and flow data. The over-etching phenomenon was likely to occur when this research team used wet etching to make microsensors. The back-end circuit integration was unlikely to be normalized. Therefore, this study used lift-off process to further stabilize the quality of the microsensor. In addition, the PEMWE is more prone to aging and damage under high pressure, so its material selection is very important. [ABSTRACT FROM AUTHOR]

The prognostic impact of LNR with respect to cause-specific survival (CSS) and overall survival (OS) was analyzed.Results: A total of 118 patients with SCCC were identified. The median follow-up was 30.5 months. All these patients were treated with cancer-directed surgery and lymphadenectomy. Sixty (50.8%) patients had nodal metastases. The median LNR was 0.16 in patients with positive lymph nodes. Univariate analysis showed that prognostic factors such as International Federation of Gynecology and Obstetrics (FIGO) stage, nodal status, LNR, and local treatment modalities affected CSS and OS (P<0.05). Multivariate analysis showed that LNR was an independent prognostic factor for CSS and OS. Patients with a higher LNR had worse CSS (hazard ratio [HR]: 8.832; 95% confidence interval [CI]: 3.762–20.738; P<0.001) and OS (HR: 8.462; 95% CI: 3.613–19.821; P<0.001). LNR was associated with CSS and OS by stage, especially in FIGO stage I–II patients.

Abstract

For the investor, the critical issue is to find the good investment information for decision making in the boundless information sea. The early stock market information is belongs opaquely. Investor, who has the first hand information, can make a big profit in stock market. In the recent years, cable TV and the Internet become more popularize. Today, they have become the major source of information to investor. The massive stock market information is propagating through above media to the investor, the phenomena named information overflow of investor. The more the information, the more the confusion of the investor. For investor, the stock market is an important channel to invest. However, the stock market can let the person become rich, also can let the person lose seriously. The key successful issue is dependent on the quality of investment information. The purpose of this paper is to analyze the behavior of investor while the information are presenting. From the results obtained, we notice that the investor first search information on the related web sites. Next, collect information from cable TV, newspapers, magazine, and consultant of investment etc. Free information of investment is primary used by investor. Secondary, they will pay the needed information at reasonable price. According the type of information, if they belong to tidings, investor can take for the timing decision. For the fundamental information, investor can use it to evaluate the current stockpsilas price. For the technical information, investor can study the trend of the stock. Finally, for the bargaining chip information, investor can predict future stockpsilas price.
