it is only when males are perpetrators that the sexual selection hypothesis is suggested as an explanation, because males potentially increase their reproductive success by reducing female remating latency33.

In light of these gaps, we pose the following research question: RQ1: What is the prevalence of interdisciplinary research among early-career scientists? To address RQ1, our analysis focuses on examining the temporal evolution of the interdisciplinarity indicator and its distributions across five ...
Every step of the research methodology (research-question formulation, hypothesis-making, data-collection plan, data analysis, interpretation...) is a smaller paper that builds onto the previous one and all of them are open for comments and reviews in order to make insights more robust and ...
Based on the hypothesis that osteocytes and osteoblasts can be irregularly stimulated to form new bones without decreasing bone resorption, anabolic therapies for osteoporosis are progressing rapidly.119 Anabolic medications, which act mainly by activating osteoblasts and osteocytes to promote new bone for...
