Abstract The working mechanism of resonant sensors is based on tracking the frequency shift in the linear vibration range.Contrary Vacuum Wine Pumps to the conventional paradigm, in this paper, we show that by tracking the dramatic frequency shift of the saddle-node bifurcation on the nonlinear parametric isolated branches in response to external f
In order to improve the prediction accuracy of groundwater pollution diffusion path, this paper combines multivariate data fusion technology to predict and analyze the groundwater pollution diffusion path.Under the special two-strategy swarm game model of water pollution particle swarm, this paper introduces replication dynamics with bounded contin
Summary: The immune-genetic changes that occur in cancer patients experiencing hyperprogressive disease (HPD) during combined immunotherapy are unclear.In this study, HPD patients with pre- and post-HPD samples and non-HPD patients with solid tumors were molecularly characterized by genetic and tumor immune microenvironment (TiME) analyses of paire
Introduction: The release of metallic ions from orthodontic brackets and wires typically depends on their quality (chemical composition) and the medium to which they are exposed, e.g., acidic, alkaline, substances with a high fluoride concentration, etc.This review examines corrosion and wear of orthodontic brackets, wires, and arches exposed to di
In order to study the effect of soil salt content on the corrosion of buried metal by the stray current in urban rail transit, a small experimental platform for the buried metal corrosion is built.The corrosion rate and mass loss of buried carbon steel specimens in soil samples with or without DC stray current are measured and calculated when diffe
