Two opposing concepts of Atlantic herring, Clupea harengus L., population structure are critically reviewed with the objective of unifying these divergent views under the metapopulation concept. It is concluded that neither the discrete population concept nor the dynamic balance concept adequately explains ...
We call for a stricter definition and use of the term 'metapopulation', critically evaluate the applicability of metapopulation theory to marine population dynamics and its use in the related literature, and consider two published case-studies that investigate metapopulation structuring in specific marine...
(Here we consider an operative definition of 'social influence', see e.g., refs 12 and 13). These three elements have been considered by a number of models, but the interplay between them has received less attention. For example, the question of why homophily and social influence do not ...
To better highlight the key factors of the population dynamics, we rescale the variables in equations (3). First, we measure population size in terms of the fraction of resources used up, i.e.,\(n:=(c+f)/K\). This definition means that\(K\)determines the scale of population sizes,...
This meta-analysis concludes that RH is a frequent phenomenon and further harmonization in terms of RH definition and measurement would be necessary to clearly distinguish true treatment resistance from pseudo-resistance. 展开 关键词: blood pressure epidemiology hypertension meta-analysis prevalence ...
Severe cases were defined based on severe cases of America thoracic society [16] or interim guidance of World Health Organization definition [17] or severe/critical case based on China’s National Health Commission definition [18] or Acute Respiratory Distress Syndrome (ARDS) based on Berlin ...
The results were pooled by stratification of studies according to the population, injury definition and follow-up/recall period; however, heterogeneity was high. Conclusions Large differences in injury proportions between different populations of runners existed. Injury proportions were affected by the dur...

“urban” according to the U.S. Census Bureau’s definition for US locations only. Included studies had to focus on at least one population with known disparities in use of digital health tools, defined by any one of the following three characteristics: age (mean age >65 years); education...
