However, whereas there exist solid conformance checking techniques for imperative models, little work has been conducted for declarative models.
Whereas there exist now over a hundred16,17 genome-scale metabolic network reconstructions for a wide range of organisms, and a number of steps in the development of these models can now efficiently be automated18,19, the reconstruction of genome-scale metabolic networks still involves numerous manual curation steps and therefore is very time-consuming20.
Multiple reports describe higher expression of CD106 in BMSC (Refs 40, 43, 47, 48, 50, 51, 52, 53), whereas there exist some studies in which no difference was detected (Refs 49, 54).
Whereas there exists an extensive list of 2D dynamic geometry environments, the number of 3D systems is reduced.
Whereas, there exists a huge body of evidence on the association between VD and migraine in women, data on migraine in men are scarce and lacking in detail, particularly as regards migraine type.
Whereas there exists a variety of evidence-based treatments for many child behavior problems (e.g., drug treatment, psychotherapy, and parenting programs; [ 8, 9]), only few children who need these treatments can access them [ 1].
Whereas there exists a rigorous methodological framework for assessing the issues related to EmOC in Tanzania, it is more of a challenge to rigorously apply these findings to what this articles argues to be a major barrier to implementation of effective health care - the policy frameworks themselves.
We first show that when the transportation is outsourced, the problem with OU policy is NP-hard, whereas there exists a class of instances where the problem with ML policy can be solved in polynomial time.
The results revealed that the Y-doped BaZrO3 consisted of BaZr1-xYxO3 and Ba2YZrO6-d, no erosion phenomenon was observed for two kinds of refractory after melting TiNi alloys, however, a 275 μm thick reaction layer of BaZrO3 crucible was observed after melting Ti2Ni alloy, whereas, there existed only a 45 μm erosion layer for the Y-doped BaZrO3 crucible.
Note that we also derived another model (2.7) in Section 2, whereas there exists competition between immature scroungers.
In the systems of Terence Parsons, Edward N. Zalta, and Dale Jacquette, for instance, "there is an x such that … x…" is expressed by "∃x(…x…)", whereas "there exists an x such that … x…" is expressed by "∃x(E!x & …x…)", where "E!" is the existence predicate (Parsons 1980, Zalta 1983, Zalta 1988, Jacquette 1996).
