IN: The United States Coast Guard (USCG) is a branch of the United States Armed Forces and one of the country's seven uniformed services. The Coast Guard is a maritime, military, multi-mission service unique among the U.S. military branches for having a maritime law enforcement mission (with jurisdiction in both domestic and international waters) and a federal regulatory agency mission as part of its mission set. It operates under the U.S. Department of Homeland Security during peacetime, and can be transferred to the U.S. Department of the Navy by the U.S. President at any time, or by the U.S. Congress during times of war. This has happened twice, in 1917, during World War I, and in 1941, during World War II.

IN: In the 21st century, Montreal has continued to build row houses at a high rate, with 62% of housing starts in the metropolitan area being apartment or row units. Apartment complexes, high-rises, and semi-detached homes are less popular in Montreal when compared to large Canadian cities like Toronto or Vancouver but similar to some US cities, in particular Philadelphia. This may be due to these cities having developed earlier. Montreal's characteristic row houses and their iconic alleyways, balconies, and outdoor staircases have become cultural symbols of the city, featured in David Fennario's Balconville and Mordecai Richler's The Apprenticeship of Duddy Kravitz.

IN: 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''.
is 5 fold the same as 5 times?
