$$ sum_{k=0}^m {m choose k} {n choose r+k} = {m+n choose m+r}. $$ I've had a couple of ideas on how to tackle this - first, I tried to see if I could divide m and n into two separate committee/groups of size m and n. But I wasn't able to figure out what the combination would represent.
DetailsThe U.K. has extensive databases on soils, land cover and historic land use change which have made it possible to construct a comprehensive inventory of the principal terrestrial sources and sinks of carbon for approximately the year 1990, using methods that are consistent with, and at least as accurate as, the revised 1996 guidelines recommended …

DetailsC(n, r)C(r, k) = C(n, k)C(n-k, r-k), where k ≤ r ≤ n. C(n, r) is the number of ways to form an r-member committee from a group of n students. C(r, k) is the number of ways to form a 4-member committee out of a group of r students. As r is the same in both cases, it it sensible to assume that the r students selected from the initial n are ...

DetailsFinally, G k (m R j) is the loop function of the two intermediate vector mesons at resonance mass m R j, and g R j, k is the coupling of the resonance R j to the channel k. The values of G k ( m R j ) and g R j, k are calculated in Ref. [30], and for the resonances f 0 ( 1370 ), f 0 ( 1710 ), f 2 ′ ( 1525 ) and K ¯ 2 ⁎ ( 1430 ) are ...

DetailsCEP19-like protein. This family includes the centrosomal protein of 19 kDa found in eukaryotes. In humans, it is encoded for by the gene CEP19 which is also known as C3orf34. These proteins localize in the centrosomes. Centrosomes are dynamic organelles that assemble around the cenles. They organize the microtubule cytoskeleton and …
