We examine the question of physical quantities and their measurement. There are two questions; first, what does one find by measuring a physical quantity on a system whose state is known? The second is: what is a measurement process, what do we learn? These questions turn out to be difficult.Basdevant, Jean-Louis
Quantities are created by multiplying scalar values by a unit type. These units are named after common abbreviations: usemag::{length::{ft,m,mi},time::{h,s}};leta =1.0*ft;assert_eq!(a.to_string(),"1 ft");letb = a.to::<m>();assert_eq!(b.to_string(),"0.3048 m");letc ...
Physical quantities such as signal area and position are reconstructed from the raw data by the custom-developed PAX data processor. PAX operates in five stages: (1) identify “hits” due to digitized photon signals in each PMT channel individually, (2) group hits into clusters, (3) compute...
The spread, or variation, of the potential measured values about the true value is expressed as the standard deviation of the potential errors.; The standard deviations of the errors due to measurement of the quantities are related as; is the estimate of average precipitation and is the ...

CCMV has a 280 Å diameter T = 3 capsid enclosing a 180 Å diameter cavity, and it can be produced in gram quantities in infected plants. P22 VLPs assemble into a T = 7 procapsid (600 Å outer diameter) that expands to a mature capsid (650 Å diameter) after heating in vitro...
Even small quantities of rye bran increase the mechanical strength of pellets and reduce the pelletizer's energy consumption. Author Contributions: Conceptualization, K.J. and S.O.; methodology, K.J. and S.O.; software, S.O.; validation, K.J., S.O. and D.C.; formal analysis, K.J...
