The paper proposes a structure of precision motion system built on the basis of a circular multi-coordinate synchronous segment motor and reconfigurable parallel kinematic mechanism.The multi-coordinate synchronous segment motor may have from two to six movable segments depending on the design, and number of the segments generally defines an intern

ABSTRACT In late 2019, navy blue lantern the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged as the cause of a cluster of pneumonia cases in China, and the corresponding disease was designated as Coronavirus Disease 2019 (COVID-19), spreading quickly around the world resulting in a pandemic.COVID-19 is associated with a set of

Common reed (Phragmites australis) is a widespread grass species that exhibits a high degree of intraspecific variation for functional traits along environmental gradients.However, the mechanisms underlying intraspecific variation and adaptation strategies in outdoor round junction box for 3 screw base cameras response to environmental gradients on

In the past decades, various Earth observation-based time series products have emerged, which have enabled studies and analysis of global change processes.Besides their contribution to understanding past processes, time series datasets hold enormous potential for predictive modeling and thereby meet the demands of decision makers on future scenario
