A similar extremal principle in mechanics, the principle of least action, was proposed by the French mathematician and astronomer Pierre-Louis Moreau de Maupertuis but rigorously stated only much later, especially by the Irish mathematician and scientist William Rowan Hamilton in 1835.
Rossen and van Duijn (2004) showed that the theoretical justifications presented by Stone and Jenkins for their models were incorrect, but they can be derived rigorously with only some assumptions (Rossen et al. 2006; Rossen and Shen 2007; Jamshidnezhad et al. 2008a).
Those who are maintained should be observed and evaluated rigorously, not only with regard to quality, but also to their geographical and social distribution.
Correctly, Hollywood tends to police all this stuff rigorously, and only the high-end examples make it out to the wider world.
Measurements were conducted using Smoluchowski approximation, which is rigorously valid only for spherical particles.
However, in spite of the fact that many numerical evidences are in support of this property, the result is rigorously proved only when the severity of the crack is small.
In studies of the permeability of composite materials, consisting of solid isometric particles A dispersed in a polymeric matrix B, Maxwell's classical equation, rigorously valid only for very low fractional volumes (vA) of spherical particles, is often used for data analysis up to much higher vA values.
While large specimens were still common on sandy bottoms deeper than 20 m in the 1980s, several species were rigorously depleted only a decade later [54].
As this problem has a biological rather than a technical basis, in many cases the identification of heterozygotes can be rigorously established only be molecular analysis (see below).
2) The central hypothesis of the paper (Yan fluctuations are functionally relevant) can be rigorously tested only if the noisiness of Yan expression is manipulated independently from EGF signaling, e.g. by manipulating transcriptional of translational control elements of Yan.
