Comparison meaningful functions acting on some real interval are completely described as transformed coordinate projections on minimal invariant subsets. The case of monotone comparison meaningful functions is further specified. Several already known results for comparison meaningful functions and invariant functions are obtained as consequences of our description. [less ▲]

We give an interpretation of order invariant functions as scale independent functions for the aggregation on finite ordinal scales. More precisely, we show how order invariant functions can act, through discrete representatives, on ordinal scales represented by finite chains. In particular, this interpretation allows us to justify the continuity property for certain order invariant functions in a natural way. [less ▲]

Three reduced complexity equalization schemes for Zero-padded OFDM systems are described. These schemes guarantee Zero-Forcing (ZF) equalization irrespective of the channel s. Two of these schemes implement the minimum-norm ZF equalizer efficiently using QR decomposition. In the third scheme, the channel zeros are grouped as being inside or outside or on the unit circle. These groups are then equalized sequentially in a manner so as to tackle excess noise amplification. The three schemes are compared for their computational complexity and Bit Error Rate (BER) performance. It is shown that the attractive scheme depends on the system specifications. The BERComputations trade off occurring in the choice of the right algorithm is also highlighted. [less ▲]

Escherichia coli uronate isomerase and mannonate dehydrogenase were overexpressed in E. coli BL21(DE3)pLysS cells and purified to near-homogeneity. The kinetic properties of the two enzymes were investigated. The isomerase was found to be inhibited by EDTA and to be stimulated by Zn(2+), Co(2+), and Mn(2+), but not by Mg(2+) or Ca(2+). Both enzymes were used to develop a sensitive spectrophotometric assay, in which D-glucuronate is converted to D-mannonate with concomitant oxidation of NADH to NAD(+). The sensitivity of this assay permits the detection of less than 1 nmol D-glucuronate. This assay can also be used to determine the concentration of beta-glucuronides and glucuronate 1-phosphate after enzymatic hydrolysis of these compounds with beta-glucuronidase or alkaline phosphatase.

Part B. of the paper compares the basic concepts of shareholder control in Anglo-America and some states of Continental Europe. It introduces a new categorization between Implicit and Explicit Systems of Corporate Control. The first category refers to statutes that are enacted and construed with the belief that market forces influence managers. Shareholder rights to be exercised in direct contact with the corporation are thought to be relatively weak. This system is established in the Anglo-American world. In contrast, direct shareholder influence through voting and (even minority) shareholder monitoring constitute the fundaments of the Explicit System that traditionally prevailed, for example, in France and Germany. This paper provides historical, statutory and new empirical evidence from some Continental jurisdictions, and in particular Germany. It concludes that in Germany, shareholder meetings are part of Corporate Governance, while the Anglo-American corporate world traditionally understood this term to include only inter-board relationships. Part C. analyses the questions of whether, how and why Corporate Governance systems converge. This study suggests that Corporate Governance systems are likely to develop in Convergence Cycles: If a legal regime provides a particularly efficient solution to a specific problem, this solution will eventually be adopted by other Corporate Governance systems with an inferior system in respect of such problem. These Convergence Cycles will finally overcome the forces against formal convergence. The proposition of Convergence Cycles draws on historical, as well as new statutory and empirical evidence, collected by the author. Part D., finally, analyses the likely impact of convergence on ownership structures. It is likely that the answer to the question of which ownership structure is efficient depends on the stage of the business cycle that the firm is at. Firms within the same stage are likely to become more and more similar with respect to their ownership structures, until they reach an equilibrium that is set at a specific point for a particular group of firms. Thus, this paper adds a dynamic perspective to the static views that presently prevail in the debate upon the convergence of ownership structures. [less ▲]
