The phrase "a pattern must" is correct and usable in written English.
It can be used when stating a requirement or necessity regarding a pattern in various contexts, such as mathematics, design, or behavior.
Example: "For the experiment to yield valid results, a pattern must emerge from the data collected."
Alternatives: "a pattern is required" or "a pattern needs to".
To count as a convention, a reproduced pattern must be reproduced, in large part, simply because it is a precedent, not because of its intrinsic merits.
The positional parameters (b), (p), and (e) of a periodic pattern must satisfy a property ((e-b mathrm{mod}~p = 0).
The idea is that a specific pattern must be generated by one of a few well-defined and explicit alternative mechanisms.
Intuitively, a signal pattern must occur in meaningful signals with higher frequency even with a lower energy.
Analogously to the definition of topological paths, a geometrical pattern must consist of different atoms, i.e. for two atoms a i, a j it holds that i ≠ j.
The inference of such a molting pattern must therefore remain speculative.
Aside from adding malto-dextrans, a spray-drying pattern must be designed so that the juice spray dries and is cooled below the sticky point before the particle hits the dryer wall and enter the collection system.
A craniospinal fluid infusion pattern must designed which generates optimal information about these parameters, subject to strict safety constraints.
The reason why some anti-MIC antibodies have apparently shown to depict a restricted tissue expression pattern must therefore lie elsewhere e.g. genetic polymorphism [40], various N-linked glycosylation patterns (MICA has 8 potential N-linked glycosylation sites) [7], [24].
In abstract, NACC with a type 2 imaging pattern must be differentiated from other tumors in the parapharygeal space, such as neurogenic tumors and pleomorphic adenoma of the minor salivary glands.
