this is the trickiest part. You use two FIND (or SEARCH) functions, one determines the position of the first dash: FIND("-",A2). And the other returns the position of the second dash: FIND("-", A2, FIND("-",A2)+1). Then you subtract the former from the latter, ...
This chapter describes the (1) model structure of AIM/CGE (Asia-Pacific Integrated Model/Computable General Equilibrium), (2) data structure (social accounting matrix (SAM)), and (3) formula and list of sets, parameters, equations, and variables. The aim of this chapter is to present all ...
The multinomial theorem is a method to take a condensed formula, such as (5x+4)2, and find all the multinomial coefficients in the expanded series. The formula can be calculated easily to find that (5x+4)2=25x2+40x+16, showing that the multinomial coefficients are 25, 40, and 16. ...

this result for sequences of formal series. By writing A (r) ∑ (x) = aj,rxj and B (r)(x) = ∑ bj,rxj , a known Möbius inversion formula for arithmetic functions in two variables is obtained (see e.g. =-=[11]-=-). Lemma 3 is the main ingredient in the proof of ...

In many situations, you might need to conditionally count or sum cells with AND logic and OR logic at a time. Even in the latest versions of Excel, the IFs series of functions is not capable of that. One of the possible solutions is combining two or more functionsSUMIFS + SUMIFSorCOUNTIF...
ecological sample21,25,26. Lastly, the morphological complexity of serial structures can be quantified, inter alia, as the total range of variation among elements, the sum of differences between sequentially adjacent elements and the direction and magnitude of gradients and slopes along a series24,...
VEGF is one of the most important growth factors controlling angiogenesis [37]. It drives a series of well-orchestral angiopoietic events including proliferation and migration of endothelial cell, vessel sprouting, pruning and anastomosis by binding to VEGF receptors [38]. It has been reported that...
