Several classes of functions have been defined for the purpose of weakening the limitations of convexity in mathematical programming, and also for multiobjective variational problems.
The results and conclusion of this review are weakened by limitations inherent to meta-analysis and individual studies.
Service providers become hitched into software networks, regional limitations weaken, and user-base network effects kick in.
In his view, the main consequence of the revolution in government since Margaret Thatcher took over in 1979 has been to weaken the institutional limitations upon the power of the prime minister.The cabinet, Parliament, the civil service and local government all have been emasculated.
The pointed out limitations weaken the time trend comparison, but gives rise to the concern about a possible decline in registration rate since 2006.
Prey heterogeneity can mediate trophic-level responses to enrichment and weaken top-down limitation of prey communities by facilitating numerical dominance by defended prey.
Not only does this limitation weaken the accountability process, both internally and externally, but it shrinks the foundation of all decision-making processes dramatically.
Predator-mediated increases in the relative abundance of defended prey may also weaken top-down limitation of trophic-level abundance causing an increase in total prey abundance relative to prey community's lacking trait heterogeneity.
We consider whether or not each of eight potential methodological limitations could weaken this conclusion: follow-up rates, study duration, sample characteristics, the choice of outcome measures, exclusion of patients with tardive dyskinesia from assignment to perphenazine, choice of study drugs and doses, reliance on intention-to-treat analysis, and differences in prestudy treatment.
Although the aforementioned investigations were designed to provide the most reliable form of scientific evidence, they have some limitations that weaken the power of the studies, e.g., study population heterogeneity, wide age-range groups, no water and electrolyte balance, no measurement of regulatory hormones, no standardization of fluid therapy given intra-operatively, and short follow-up.
