Methods: Controlled observation method was adopted in the clinical and experimental study. Results: There was no significant difference in the treatment of dehydration between the ZXBYM group and oral rehydration solution (ORS) group (P>0.05), at the same time it was more effective for ZXBYM to eliminate such symptoms as vomiting and abdominal distension (P<0.01). In addition, it was confirmed that the ion concentration of sodium, potassium, chlorine, glucose and osmotic pressure in the mixture was similar to those in ORS. Animal experiment showed that ZXBYM has the effect of rat intestine peristalsis suppression and water absorption promotion in colon. And there was statistical difference in antidiarrhea effect between the mixture and ORS (P<0.01). Conclusion: ZXBYM is an effective mixture in the treatment of diarrhea with dehydration. It has a good prospect for the development and application.展开更多

However, a single secondary user(SU) probably can't afford the price of spectrum. Multiple SUs grouping together to participate in the auction as a whole is helpful to increase purchasing power. However, SUs could suffer from a new group cheating problem, i.e., parts of users conspire to manipulate the auction by submitting untruthful bids. Existing auction mechanisms were mainly designed to be strategy-proof only for individual user and can't deal with group cheating. In this paper, a novel spectrum auction mechanism called COSTAG(COst Sharing based Truthful Auction with Group-buying) is proposed to address the group cheating problem. COSTAG consists of a grouping rule to perform grouping and a payment rule to determine the market-clearing price in the spectrum auction. Different from single-echelon pricing approach employed in existing works, a multi-echelon pricing strategy is designed to increase the transaction rate and optimize social profit for the auction. Comprehensive theoretical analysis shows that COSTAG can satisfy the crucial economic robustness properties, both individual and group truthfulness. Simulations demonstrate that comparing with existing works, COSTAG can improve the system performance significantly.展开更多

The objective of this work is to investigate the long-run performance of IPOs of venture and non-venture-backed companies. The analysis of a sample of 102 IPOs carried out in Italy in 1998-2005 revealed that both companies （venture-backed and non-venture-backed） showed negative values, thus, confirming the phenomenon of underperformance. During the 36 months following their listing, venture-backed companies seemed to register negative and statistically significant values both with the CARsVB methodology （-93.99%） and the Buy and Hold Abnormal Returns methodology （BHARsVB -88.37%）. Venture-backed companies, unlike non- venture-backed companies, seem to be able to restrain the losses, measured by both methods, in the first 12 months （CARsB - 12.38% -20.15% CARSNNVB; BHARsVB - 10.17%; BHARsNVB - 15.51%）. During the 36 months, however, the IPOs showed negative and statistically significant values regardless of whether they were venture or non-venture-backed. The test on the difference between the average abnormal returns of the two methodologies （CAARS and BHAARs） did not produce statistically significant results. The Wealth Relative was calculated and from the results it would appear that the portfolio of venture-backed IPOs does not register ＂brilliant＂ performances. The portfolio of 102 IPOs does not seem to beat the ＂market portfolio＂. In conclusion, therefore, the phenomenon of underperformance seems to be real in our country and is documented by strongly negative and statistically significant values obtained from the samples of IPOs analyzed.展开更多

文摘Spectrum auction is an important approach of spectrum distribution in cognitive radio networks. However, a single secondary user(SU) probably can't afford the price of spectrum. Multiple SUs grouping together to participate in the auction as a whole is helpful to increase purchasing power.
