[3] [4] In June 2011 Edexcel announced that the AEA was being extended further for mathematics, until June 2015, which was later extended until 2018. [ 5 ] In 2018, Edexcel introduced a new specification, meaning the Advanced Extension Award in mathematics would continue to be available to students in 2019 and beyond, as a qualification aimed ...
The quaternion solution to compute the optimal rotation was published in the appendix of a paper of Petitjean. [5] This quaternion solution and the calculation of the optimal isometry in the d-dimensional case were both extended to infinite sets and to the continuous case in the appendix A of another paper of Petitjean.

In calculation, the effects of r o are negligible, [1] so the equation is typically expressed as: λ = r m r i {\displaystyle \lambda ={\sqrt {\frac {r_{m}}{r_{i}}}}} The membrane resistance is a function of the number of open ion channels , and the axial resistance is generally a function of the diameter of the axon .
The constants listed here are known values of physical constants expressed in SI units; that is, physical quantities that are generally believed to be universal in nature and thus are independent of the unit system in which they are measured.
In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field. Physics is derived of formulae only.
A 1999 analysis concluded that biomass production in a given plant scaled with the 3 ⁄ 4 power of the plant's mass during the plant's growth, [31] but a 2001 paper that included various types of unicellular photosynthetic organisms found scaling exponents intermediate between 0.75 and 1.00. [32] Similarly, a 2006 paper in Nature argued that ...
Two decades since the first eukaryotes were sequenced, the "biological role" of around 20% of proteins are still unknown. [10] Many of these proteins are conserved across most eukaryotic species and some are conserved in bacteria, indicating a role fundamental for life.
Molecular biology – study of biology and biological functions at the molecular level, with some cross over from biochemistry. Structural biology – a branch of molecular biology, biochemistry, and biophysics concerned with the molecular structure of biological macromolecules. Health sciences and human biology – biology of humans.
