Multiple Launch Rocket System (MLRS) has been widely used in color touch 7/97 recent years; vibration control in launching process is an effective way to improve its dispersion characteristics.In this paper, a novel vibration control system applying Annularly Arranged Thrusters (AAT) for MLRS in launching process is introduced and the prototype of
To clarify the heavy metal(loid) contamination characteristics and health risk in nine typical greenhouse production areas in Jingmen, Central China, the total concentrations of As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn in 176 soils and 332 vegetables were analyzed.Cadmium (100%) and Ni (4/44) exceeded the color touch 7/97 Chinese standard limits, while A
Out-of-sample prediction for the final portion of a sample is a popular tool for model selection in model-based forecasting.We suggest to add a simulation step to this exercise, where pseudo-samples are generated (parametrically bootstrapped), conditional on the observed data and on any of the candidate models, and these pseudo-samples are predicte
Chronic Obstructive Pulmonary Disease (COPD) affects 30 million Americans.Previous epidemiologic work has shown that diet can impact pulmonary function in those with and without COPD.Diet is also a major driver of gut microbiome composition and function.Importantly, the gut microbiome has also been associated with lung health (i.e., the gut-lung ax
