Fold change is so-called as it is common to describe an increase of multiple X as an ''X-fold increase''. As such, several dictionaries, including the Oxford English Dictionary and Merriam-Webster Dictionary, as well as Collins's Dictionary of Mathematics, define ''-fold'' to mean ''times,'' as in ''2-fold'' = ''2 times'' = ''double.'' Likely because of this definition, many scientists use not only ''fold'' but also ''fold change'' to be synonymous with ''times'', as in ''3-fold larger'' = ''3 times larger.''. More ambiguous is fold decrease, where for instance a decrease of 50% between two measurements would generally be referred to a ''half-fold change'' rather than a ''2-fold decrease''.

A semi-presidential system or dual executive system is a system of government in which a president exists alongside a prime minister and a cabinet, with the latter being responsible for the legislature of a state. It differs from a parliamentary republic in that it has a popularly elected head of state, who is more than a purely ceremonial figurehead, and from the presidential system in that the cabinet, although named by the president, is responsible to the legislature, which may force the cabinet to resign through a motion of no confidence.
can a country have both a president and a prime minister?

Goring is much less common but potentially life threatening. In 2013, for example, six participants were gored along the festival, in 2012, only four runners were injured by the horns of the bulls with exactly the same number of gored people in 2011, nine in 2010 and 10 in 2009; with one of the latter killed. As most of the runners are male, only 5 women have been gored since 1974. Before that date, running was prohibited for women.
