Background Higher concentrations of 25-hydroxyvitamin D3 [25(OH)D3] at diagnosis are associated with a lower mortality risk in colorectal cancer (CRC) patients. However, magnesium and calcium are important in vitamin D metabolism.

Recurrence Relations for Moments of Dual Generalized Order Statistics from Weibull Gamma Distribution and Its Characterizations [PDF]
In this paper, we establish explicit forms and new recurrence relations satisfied by the single and product moments of dual generalized order statistics from Weibull gamma distribution (WGD).

Orthogonal polynomials of dimension –1 in the non-definite case [PDF]
: Orthogonal polynomials of dimension d = −1 are a particular case of vector orthogonal polynomials which are, themselves, a particular case of biorthogonal polynomials.

Number of spanning trees of some families of graphs generated by a triangle
In mathematics, one always tries to get new structures from given ones. This also applies to the realm of graphs, where one can generate many new graphs from a given set of graphs.

On fourth-order jacobsthal quaternions
In this paper, we present for the first time a sequence of quaternions of order 4 that we will call the fourth-order Jacobsthal and the fourth-order Jacobsthal-Lucas quaternions. In particular, we are interested in the generating function, Binet formula,

Probabilistic recurrence relations revisited
AbstractThe performance attributes of a broad class of randomised algorithms can be described by a recurrence relation of the form T(x) = a(x) + T(H(x)), where a is a function and H(x) is a random variable. For instance, T(x) may describe the running time of such an algorithm on a problem of size x.

Special formulas involving polygonal numbers and Horadam numbers
Some convolution-type identities involving polygonal numbers and Horadam numbers are derived. The method of proof is to properly relate the generating functions to each other.

Fast calculation of computer-generated hologram using run-length encoding based recurrence relation.
Computer-Generated Holograms (CGHs) can be generated by superimposing zoneplates. A zoneplate is a grating that can concentrate an incident light into a point.
