Despite almost 15 years of attempts, well defined, workable definitions for plant PCD types based on morphology are still being developed.
In fact, I am not sure that the concept of integrators and resonators is well defined with a definition that has a broad consensus.
For example, pricing default bonds, pricing complex insurance contracts, as well as complex network risks of various granularity, that have well defined and quantitative definitions of their hazard rates.
Each element in S is said to be a coordinated (line) segment relative to S. Coordinates relative to a set S are well defined in the preceding definition in the sense that different elements in S have different coordinates, as proved next.
There is no well defined and international accepted definition of optimal serum 25-hydroxyvitamin D value for bone and nutritional health [28], [29], but low plasma 25-hydroxyvitamin D and secondary hyperparathyroidism are the biochemical hallmarks for insufficient vitamin D status [2].
This may be due to our use of the standardised protocol by IAMMM [ 30], including a standardised training procedure for the examiners, a protocol with well defined procedures and operational definitions that provided quantifiable values.
Remark 5.2 Let us observe that the condition (SM2) of Definition 5.3 implies that the inverse under soft mapping T in Definition 5.5 is well defined.
end{aligned} (29) The above definitions are well defined by Lemma 1(i).
In many cases, these concepts are very well defined and managed by community definitions such as the IUPAC Gold Book [35].
Thus, Definition 2.7 is well defined (see [48, 54]).
Such a definition is not well defined in the event that {w′ | (M,w′) ⊧ ϕ} ∉ Aw.
