Abstract The recent observations of exotic quantum phenomena in AV3Sb5 (A = K, Rb, Cs) kagome superconductors have attracted significant attention in materials physics.Here, we propose an innovative two-frequencies laser model for ultrafast control of transient structural distortions.Using first-principles density functional theory in conjunction w
In this paper, we propose a new method for estimating and forecasting asymmetric stochastic volatility models.The proposal is based on dynamic linear models with Markov switching written as state Planner space models.Then, the likelihood is calculated through Kalman filter outputs and the estimates are obtained by the maximum likelihood method.Mont
Spiral water jackets are essential refrigeration units in motorized spindles.The design of spiral water jackets directly affects the machining accuracy PURE CRANBERRY JUICE and reliability of motorized spindles.In this regard, a reliability-based design optimization (RBDO) method is presented to obtain the optimal configuration of the spiral water
COVID-19 has exposed the vulnerability of our economies to shocks, and it has laid bare deep inequalities in our society that threaten to derail the Sustainable Development Goals.Governments around the world are looking for recovery options that deliver new jobs and businesses.Few sectors link job creation so closely to sustainable green production
