Propensity score matching (PSM) is a quasi-experimental method in which the researcher uses statistical techniques to construct an artificial control group by matching each treated unit with a non-treated unit of similar characteristics.

Fatigue: The process of progressive localized permanent structural damage occurring in a material subjected to conditions that produce fluctuating stresses and strains at some point or points and that may culminate in cracks or complete fracture after a sufficient number of fluctuations. (American Society for Testing and Materials Standard E 1150 )
An animal housing system consisting of a stall or pen with a slightly sloping floor with straw being provided or dispensed at the top of the slope and “flowing” down the slope to be collected as solid manure at the bottom.

The absolute vorticity is computed from the air velocity relative to an inertial frame, and therefore includes a term due to the Earth's rotation, the Coriolis parameter. (https://en.wikipedia.org/wiki/Vorticity)
Any physical (or biological) object or condition obstructing free interchange along what would otherwise be an open corridor. Barriers may be more effective for some functional or taxonomic groups than others (cf pathway, corridor). (Johnson, R.K., B.J. Zahuranec, D. Boltovskoy and A.C. Pierrot-Bults. 2000.

Laminar flow is the property of fluid particles in fluid dynamics to follow smooth paths in layers, with each layer moving smoothly past the adjacent layers with little or no mixing. (Streeter, V.L. (1951-1966) Fluid Mechanics, Section 3.3 (4th edition). McGraw-Hill)
Any waste that emit radiation in excess of normal background level, including the toxic by-products of the nuclear energy industry. (https://www.eionet.europa.eu/gemet/en/concept/6921)
