Mathematical symbols serve as verbs. Equations are punctuated as sentences. Do not use italics for foreign and Latin words which have become common in English text. Reserve italics in text for emphasis. No hyphens are used in words formed with prefixes.
Examples are nonlinear, semimajor axis, antisymmetric.
Do not use newly invented acronyms or tradenames to describe your technique. Do not put a hyphen between an adverb and the word it modifies, e.g., horizontally layered. Physical quantities should be expressed in SI units. Exceptions to this rule, at the discretion of the Editor, will be permitted when field measurements were obtained or equipment was specified with different units. Do not carry more significant figures in the unit conversion than were used in the original measurement.
