... The diameters of atomic nuclei are about 10-4A. Thus, the nuclei are about 0.01% the diameter of the atom as a whole. If the nucleus had a diameter equal to that of a pinhead, then the atom itself would have a diameter of some 10 meters (about 39 and a half feet). The nucleus of an atom is therefor ...

Sample Exercise 19.1 Identifying Spontaneous Processes
... (a) Equation 19.12 tells us that ΔG° is the sum of the enthalpy term ΔH° and the entropy term –T ΔS°. The temperature dependence of ΔG° comes from the entropy term. We expect ΔS° for this reaction to be negative because the number of molecules of gas is smaller in the products. Because ΔS° is negati ...

Fast Molecular Shape Matching Using Contact Maps
... The overall algorithm is similar to the one described in Goldman et al. (1999). Given two two-dimensional contact maps G1 and G2, we first decompose G1 into two 2-stacks and two 2-staircases. Each 2-staircase is then decomposed into two 1-staircases in linear time. We then compute the maximum overla ...
