High-speed railway catenaries are vital components in railway traction power supply systems.To ensure stable contact between the pantograph and the catenary, droppers are positioned between the messenger wire and contact line.The failure of one or more droppers will affect the power supply of the catenary and the operation of the railway.In this pa
Typhoons often cause huge losses, so it is significant to accurately predict typhoon tracks.Nowadays, researchers predict typhoon tracks with the single step, while the correlation of adjacent moments data is small in long-term prediction, due to the large step of time.Moreover, recursive multi-step prediction results in the accumulated error.There
The mammary epithelium consists of multiple phenotypically and functionally distinct cell populations, which are organized as a hierarchy of stem cells, progenitors and terminally differentiated cells.Identification of the mechanisms regulating the growth and differentiation of mammary stem and progenitor cells is of great interest not only to bett
Abstract Background The flowering transition which is controlled by a complex and intricate gene regulatory network plays an important role in the reproduction for offspring of plants.It is a challenge to identify the critical transition state as well as the genes that control the transition of flower development.With the emergence of massively par
Scholars critique LGBTQ+ social movements for failing to understand how oppressive systems like racism inform the experiences of LGBTQ+ APPLE community members.To investigate whether LGBTQ+ literature in postsecondary education reproduces this same pattern, we used a critical summative content analysis approach to examine research published on LGBT
