(a) Using the expansion of ln(1+x) given in Eq. (2.41), show that, for sufficiently large n, (i)1n+lnn-1n<0,(ii)1n-lnn+1n>0. (b) Use these inequalities to show that the limit defining the Euler- Mascheroni constant, Eq. (2.13), is finite.2.5...
Expansion of outreach through government AIDS centers is needed to prevent the spread of HIV in Russia. Orel Russia is the site of a pilot project in HIV community outreach conducted by the US Centers for Disease Control and Prevention and the Russian Ministry of Health. We sought to determine...
After stratification, the 1-, 3-, and 5-year RFS of patients exceeding the Milan but fulfilling the Hangzhou criteria with PLR < 120 were 84.2%, 73.3%, and 73.3%, respectively, comparable with 85.7%, 73.9%, and 72.8%, respectively, in patients fulfilling the Milan criteria (P =...
A more pronounced negative thermal expansion behavior has been discovered in single crystals of PBAs, MIIPtIV(CN)6⋅xH2O (0 ≤ x≤ 2; M = Zn, Cd) [90]. Temperature dependent structural analysis on the lattice parameters manifests the negative thermal expansion behavior of each phase. A ...

Performing this analysis for each mesh density, the x velocities could be used to compare reattachment lengths as shown in Fig. e1.8. The importance of mesh refinement on the reattachment length can be clearly seen on these plots (Fig. e1.8). The reattachment location increases with the ...
