The dimension of a vector space is the number of vectors in the basis. Can a matrix have a basis? A matrix cannot have a basis. However, a basis can be found for the column space, row space, or null space of a matrix. How do you find the basis of a vector space? To find the...
For a long time, I told the story of US R&D funding in this way: There was a big run-up in US R&D spending in the 1950s and into the 1960s, driven largely by US government R&D spending typically aimed at military and space programs. However, federal R&D spending as a share of GDP...

My latest “In Good Faith” column reminds us that it’s okay to keep downing Peeps — the advantage of living into the 50-days of Eastertide. Extending the Joy Fear not. For behold, I bring you tidings of great joy: Easter is not just a single day but a 50-day season of resurrec...
The proposed metric’s p-value (Mb in column 1) is consistently lower than that of the other five similarity measures. The average p-values of 71 pathways for the six similarity measures in the order listed in Table 1 are 0.02, 0.31, 0.12, 0.26, 0.17, 0.19 respectively. The number of...
The key idea behind the application of visualization algorithms for the validation of DEGs is that if the DEGs are used as features to project the samples, the samples of different classes should be projected to distinct locations in the projected space else a random projection pattern is ...
The forth column illustrates the number of obstacles verified by the VC2 algorithm. Note that the underlined obstacles are ignored by the VC2 algorithm. For example, when checking the visibility of 𝑝4p4 (see the seventh row), the VC algorithm examines six obstacles, while the VC2 algorithm ...
In addition, there are two main proteomic workflows, which include (1) top-down (mass spectrometry technique that analyses intact proteins) and (2) bottom-up (measures digested peptide mixtures through column separation, followed by mass spectrometry analysis) [90,91]. Proteomic studies using ...
is a basis of u ⊥ , u ⊥ , adjoining u 1 = u u 1 = u gives a basis u = ( u 1 , u 2 , … , u n ) u = ( u 1 , u 2 , … , u n ) for the entire space. because obviously i n u j = u j i n u j = u j for all j = 1 , 2 , … , n j = 1...
