Abstract: The invention relates to a compound according to the following general formula (I), in which: m represents an integer equal to 5, 6 or 7; n and n1 represent an integer from 1 to 5; the A groups represent, in particular, a hydrogenated atom; X represents O or S; Y represents, in particular, a group NR1, R1, representing, in particular, a hydrogenated atom; W represents CH or N; and Z represents, in particular, a hydrogenated atom.

Abstract: Raceway for electrical cables having a channel-shaped base element made up of a flat bottom wall, and two side walls which form with the flat bottom wall respective blunt edges and which have a plurality of narrow cut-outs that are parallel and extend perpendicular to the flat bottom wall and a series of slits arranged between the flat bottom wall and the narrow cut-outs. Each slit extends as far as the flat bottom wall, completely sectioning the blunt edge that the slit forms with the side wall The flat bottom wall is provided with a weakening line extending parallel to the blunt edge. The raceway allows a cable to be deviated through one of the side walls without having to deviate the cable vertically, by breaking away one of vertical flanges (20) defined between two the narrow cut-outs.

Abstract: Method and apparatus for determining a concentration coefficient for an asset portfolio. The concentration coefficient is determined according to the inverse of the sum of the squares of the weights of each holding in the portfolio, and expresses portfolio concentration as an equivalent number of equal-weighted holdings. In this manner, a balanced portfolio that is not weighted toward any particular holding or security is already relatively equally-weighted, and its concentration coefficient will approach the number of holdings it has. Conversely, a portfolio concentrated in few holdings will have a concentration coefficient that is lower than the number of holdings in the portfolio. Accordingly, a concentration coefficient value significantly lower than the total number of holdings generally indicates a more “concentrated” portfolio, while a concentration coefficient value approaching the total number of holdings of a portfolio indicates that the portfolio is not concentrated, and relatively “balanced.
