Two 100?MHz ADC modules worked parallelly and every ADC plays out data in ping pang fashion. The design improved the system conversion rata to 200?MHz and reduced the speed of data transporting and storing to 50?MHz. The high speed HDPLD and ECL logic parts were used to control system timing and the memory address. The multi layer print board and the shield were used to decrease interference produced by the high speed circuit. The system timing was designed carefully. The interleaving/multiplexing technique could improve the system conversion rata greatly while reducing the speed of external digital interfaces greatly. The design resolved the difficulties in high speed system effectively. The experiment proved the data acquisition system is stable and accurate.展开更多

In the current challenging business environment, acquisitions face a higher degree of risk profiles, especially cross-border acquisitions in the emerging markets. Conducting a thorough due diligence investigation in the context of an acquisition is more important now than ever. In a broad analysis, this paper researches the key risk factors in the acquisition process and their assessment within a due diligence audit in the acquisition phase. The task of this paper is to match the academic and practical view in order to give a more complete understanding of risk factors to be covered in due diligence audit. The starting point is the research of academic findings which basically concentrate on common approaches considering financial, legal, commercial, and some other issues in domestic acquisitions and in developed countries. In contrast, this paper considers risk factors in cross-border and emerging markets transactions. In addition, a number of business consultants publish studies based on surveys on this topic which reflect typical risk factors based on experience of their customers being involved in cross-border acquisitions. Their risk assessment consists of specific regulatory, political, and other factors, which may lead to commercial and reputational impediments in cross-border acquisitions. The outcome of the comparison is a comprehended list of evaluated risk factors, whereby the academic findings are complemented and supported by the practical experience in the business consultant＇s studies. Moreover, the practical approach points to the fact that due diligence scope needs to be suited to the dynamics of the markets. The comparison and the comprehended list of evaluated risk factors call for a more integrated system of due diligence and show herein the research deficit. Hence, the novelty is the compendium of evaluated risk factors which should be assessed in the pre-acquisition phase. The originality of the paper is given by a unique analysis of academic work about acquisition due diligence literature and consultant studies from anonymized practical experience based on insider information.展开更多

Using 125valid collected questionnaires, multiple linear regression analysis and hierarchical regression analysis showed that five out of the ten factors had a positive effect on knowledge transfer effect. The ranking of factor importance, from high to low, was knowledge explicitness, relationship quality, learning intent, advanced transfer activities, and learning capability, which is fairly consistent with positive factors observed in other interorganizational knowledge transfer researches. Our results also showed that one of the control variables(size of acquired firm) had neither a direct or indirect effect on knowledge transfer in M&A. Additionally, our research found that knowledge distance and degree of M&A integration had a positive influence on knowledge transfer effect at the early stage after M&A, but had a negative influence at the late stage. Based on this research, several suggestions for knowledge transfer in M&A are proposed.展开更多

If the capital market is competitive, the investors cannot expect superior gains from their investment strategies with respect to the risk profile. Event studies are an approach to verify the impact of the information on the stock prices. In an efficient market, stock prices should fully, promptly, and quickly capture all the information. Instead, the market shows phenomena of an under-reaction and over-reaction for both the short and the long run. The mergers and acquisitions （M＆As） are examples of anomalies. Often, the bidder companies record the negative abnormal returns for both the short and the long run. In contrast to the efficient market theory, the empirical evidence shows that this phenomenon is widespread in all （or most of） the countries of the world. This work examines the long-run performance in M＆As. For this purpose, 40 bidders were observed in Italy during the period of 1994-2008 among listed companies. The buy and hold abnormal returns （BHARs） methodology was used, with which it was possible to observe the returns for three years following the deal.展开更多

Meanwhile, the trade policy of the host government is taken into account. It is concluded that the more open the economy and the more intense the competition, the less profitable the integration; the most important determinant to the changes of the domestic social welfare is the industry strength of the host country. The host authority can enhance the domestic social welfare in two ways： to adjust the trade policy and to only approve the socially desirable cross-border mergers and acquisitions.展开更多

Enterprises go through the process of Mergers and Acquisitions (M&A) with the goal of improving performance, increasing efficiency and obtaining business synergy. Prior literature suggests that synergies could arise due to taxes, market power or efficiency improvements. This study evaluates the efficiency of M&A in Brazil among publicly-traded companies. We used models with multiple objectives from Goal Programming and Data Envelopment Analysis (GPDEA), employing accounting indicators as input and output variables, and thus evaluated the emergence of synergy gains. These models allow us to analyze and classify the M&A according to the efficiency obtained in such processes. Some of the M&A cases analyzed were mistakenly considered efficient when used traditional models. And, as expected, the GPDEA was proved to be superior to classical models;however it was noticed that few of the cases investigated were proved to be effective. We presented a new application for multi-objective approach that can be used to assess mergers and acquisitions. The dualapplication of GPDEA provided a greater understanding of efficiency generation in synergy creation by means of M&A.展开更多

One of such tools refers to acquisitions through which companies can profit from synergic effects, reduce operating cost and tax expenses, and improve their market position. This paper is aimed at examining the effect of cross-border acquisitions made by Slovak companies in order to improve their performance. Authors applied the method of simultaneous equation model to examine this relation. The result confirmed the hypothesis that cross-border acquisitions positively influence a company performance.展开更多

Meanwhile, the trade policy of the host government is taken into account. It is concluded that the more open the economy and the more intense the competition, the less profitable the integration; the most important determinant to the changes of the domestic social welfare is the industry strength of the host country. The host authority can enhance the domestic social welfare in two ways： to adjust the trade policy and to only approve the socially desirable cross-border mergers and acquisitions.
文摘This article sheds light on how synergies arise through mergers and acquisitions (M&A). Enterprises go through the process of Mergers and Acquisitions (M&A) with the goal of improving performance, increasing efficiency and obtaining business synergy. Prior literature suggests that synergies could arise due to taxes, market power or efficiency improvements. This study evaluates the efficiency of M&A in Brazil among publicly-traded companies. We used models with multiple objectives from Goal Programming and Data Envelopment Analysis (GPDEA), employing accounting indicators as input and output variables, and thus evaluated the emergence of synergy gains. These models allow us to analyze and classify the M&A according to the efficiency obtained in such processes. Some of the M&A cases analyzed were mistakenly considered efficient when used traditional models. And, as expected, the GPDEA was proved to be superior to classical models;however it was noticed that few of the cases investigated were proved to be effective. We presented a new application for multi-objective approach that can be used to assess mergers and acquisitions. The dualapplication of GPDEA provided a greater understanding of efficiency generation in synergy creation by means of M&A.
文摘Currently, businesses or companies apply various tools of financial engineering on improvement of their performance. One of such tools refers to acquisitions through which companies can profit from synergic effects, reduce operating cost and tax expenses, and improve their market position. This paper is aimed at examining the effect of cross-border acquisitions made by Slovak companies in order to improve their performance. Authors applied the method of simultaneous equation model to examine this relation. The result confirmed the hypothesis that cross-border acquisitions positively influence a company performance.

文摘Phosphorus(P)is an essential nutrient for crop growth,making it important for maintaining food security as the global population continues to increase.Plants acquire P primarily via the uptake of inorganic phosphate(Pi)in soil through their roots.Pi,which is usually sequestered in soils,is not easily absorbed by plants and represses plant growth.Plants have developed a series of mechanisms to cope with P deficiency.Moreover,P fertilizer applications are critical for maximizing crop yield.Maize is a major cereal crop cultivated worldwide.Increasing its P-use efficiency is important for optimizing maize production.Over the past two decades,considerable progresses have been achieved in studies aimed at adapting maize varieties to changes in environmental P supply.Here,we present an overview of the morphological,physiological,and molecular mechanisms involved in P acquisition,translocation,and redistribution in maize and combine the advances in Arabidopsis and rice,to better elucidate the progress of P nutrition.Additionally,we summarize the correlation between P and abiotic stress responses.Clarifying the mechanisms relevant to improving P absorption and use in maize can guide future research on sustainable agriculture.
