  2. Number bond - Wikipedia

    en.wikipedia.org/wiki/Number_bond

    For example, a number bond looks like + = A child who "knows" this number bond should be able to immediately fill in any one of these three numbers if it were missing, given the other two, without having to "work it out". Number bonds are often learned in sets for which the sum is a common round number such as 10 or 20. Having acquired some ...

  3. Duration (finance) - Wikipedia

    en.wikipedia.org/wiki/Duration_(finance)

    For a standard bond, the Macaulay duration will be between 0 and the maturity of the bond. It is equal to the maturity if and only if the bond is a zero-coupon bond. Modified duration, on the other hand, is a mathematical derivative (rate of change) of price and measures the percentage rate of change of price with respect to yield.

    WAL should not be confused with the following distinct concepts: Bond duration Bond duration is the weighted-average time to receive the discounted present values of all the cash flows (including both principal and interest), while WAL is the weighted-average time to receive simply the principal payments (not including interest, and not discounting).

  6. Three-center two-electron bond - Wikipedia

    en.wikipedia.org/wiki/Three-center_two-electron_bond

    In many common bonds of this type, the bonding orbital is shifted towards two of the three atoms instead of being spread equally among all three. Example molecules with 3c–2e bonds are the trihydrogen cation (H + 3) and diborane (B 2 H 6). In these two structures, the three atoms in each 3c-2e bond form an angular geometry, leading to a bent ...

  7. Inverted yield curve - Wikipedia

    en.wikipedia.org/wiki/Inverted_yield_curve

    An inverted yield curve is an unusual phenomenon; bonds with shorter maturities generally provide lower yields than longer term bonds. [2] [3] To determine whether the yield curve is inverted, it is a common practice to compare the yield on the 10-year U.S. Treasury bond to either a 2-year Treasury note or a 3-month Treasury bill. If the 10 ...

    Draw the structure in your molecule editor (ideally change the settings to give a molecule twice the size as the JACS standard or change the size to 200% before next step), and save it as an Encapsulated PostScript file (.eps) - many of the Apple print drivers (an Apple printer is not required) that print to a PostScript printer can be set to ...
