Finally, to the best of our knowledge, all other constraints on the mechanism, most of which are not directly tied to D2 binding, are satisfied, as well.
In our studies, constraints were designed from our knowledge of the family classifications of the sequences resulting in four constraints.
As a bastion of what is known as hard science fiction, Analog encourages writers to keep the scientific content of their stories plausible, or at least possible within the constraints of current knowledge.
In contrast to universal approaches, like the dual decomposition method, we fully exploit our knowledge of active constraints of the joint optimization problem.
As opposed to the universal dual decomposition we present a method that solves this optimization problem by fully exploiting our knowledge of active constraints.
Reasons for irrational antibiotic prescribing are the same as in other countries: perceived patient expectation; time constraints; lack of knowledge; lack of diagnostics; pressure, incentives and advertising from industry; and financial benefits for the prescriber [ 13].
Monetary constraints, absence of knowledge about the need of services, and restrictions on the movement of women were also cited as reasons for not accessing antenatal care.
The main obstacles to take-up are constraints of money, time and knowledge that limit teachers' ability and willingness to apply new teaching techniques.
The study also demonstrated that although the majority of PNs were willing to become more involved in chlamydia testing and just over half in partner notification, they identified potential barriers to increasing testing including time constraints, lack of patient knowledge and lack of formal reminder systems to facilitate repeat testing.
Without a robust notion of truth, without the reassurance of constraints on knowledge beyond those that humans choose to place on themselves, a person's outlook is liable to become cynical, self-interested, power-obsessed.
