This study was designed to examine the narrative language abilities of children and adolescents with Down syndrome in comparison to same-age peers with fragile X syndrome and younger typically developing children matched by nonverbal cognitive ability levels.Participants produced narrative retells from a wordless picture book.Narratives were analyz

Transmission error (TE) and backlash are important parameters used to evaluate the transmission accuracy of cycloid-pin drives.Existing calculation methods are mostly based on two-dimensional tooth profile models, and these methods ignore the influence of some abnormal meshing phenomena caused by profile modifications (PMs), manufacturing errors (M

Promoting the permeability of deep, low-permeability coal seams through biological means is currently a research hotspot for enhancing the efficiency of coalbed methane extraction.In this study, we selected anthracite coal from Sihe Mine for microbial anaerobic degradation culture experiments.The effects of adding functional microorganisms on the m

Abstract Simulating lattice gauge theory (LGT) Hamiltonian and its nontrivial states by programmable EA Furniture quantum devices has attracted numerous attention in recent years.Rydberg atom arrays constitute one of the most rapidly developing arenas for quantum simulation and quantum computing.The $${{mathbb{Z}}}_{2}$$ Z 2 LGT and topological ord
