    where t R is the retention time and w b is the peak width at baseline. The bigger the time-difference and/or the smaller the bandwidths, the better the resolution of the compounds. The bigger the time-difference and/or the smaller the bandwidths, the better the resolution of the compounds.

  3. Erythrocyte aggregation - Wikipedia

    en.wikipedia.org/wiki/Erythrocyte_aggregation

    Erythrocyte aggregation is a physiological phenomenon that takes places in normal blood under low-flow conditions or at stasis. The presence or increased concentrations of acute phase proteins, particularly fibrinogen, results in enhanced erythrocyte aggregation.

    Consequently, the row space of J is the subspace of spanned by { r 1, r 2, r 3, r 4}. Since these four row vectors are linearly independent , the row space is 4-dimensional.

  5. Area density - Wikipedia

    en.wikipedia.org/wiki/Area_density

    A special type of area density is called column density (also columnar mass density or simply column density), denoted ρ A or σ. It is the mass of substance per unit area integrated along a path; [ 1 ] It is obtained integrating volumetric density ρ {\displaystyle \rho } over a column: [ 2 ] σ = ∫ ρ d s . {\displaystyle \sigma =\int \rho ...

    In database management, an aggregate function or aggregation function is a function where multiple values are processed together to form a single summary statistic. (Figure 1) Entity relationship diagram representation of aggregation. Common aggregate functions include: Average (i.e., arithmetic mean) Count; Maximum; Median; Minimum; Mode ...

    A (1, 1) = Trapezoidal (f, tStart, tEnd, h, y0) % Each row of the matrix requires one call to Trapezoidal % This loops starts by filling the second row of the matrix, % since the first row was computed above for i = 1: maxRows-1 % Starting at i = 1, iterate at most maxRows - 1 times % Halve the previous value of h since this is the start of a ...

  8. Aggregate modulus - Wikipedia

    en.wikipedia.org/wiki/Aggregate_modulus

    In relation to biomechanics, the aggregate modulus (Ha) is a measurement of the stiffness of a material at equilibrium when fluid has ceased flowing through it. [1] The aggregate modulus can be calculated from Young's modulus (E) and the Poisson ratio (v). [1] [2] = (+) ()

    en.wikipedia.org/wiki/Rank_factorization

    Let be an permutation matrix such that = (,) in block partitioned form, where the columns of are the pivot columns of .Every column of is a linear combination of the columns of , so there is a matrix such that =, where the columns of contain the coefficients of each of those linear combinations.
