Earliest simultaneous multi-color optical observations of GRB 230328B: from 41 seconds to the host-galaxy identification

Abstract We present a multiwavelength study of the long-duration gamma-ray burst GRB 230328B, combining prompt γ-ray observations with exceptionally early simultaneous optical photometry and extensive X-ray, radio, and host-galaxy follow-up. NUTTELA-TAO began simultaneous g′r′i′...

Novel Exact Solutions of the Duffing Equation: Stability Analysis and Application to Real Non-Linear Deformation Tests

In this study, novel exact solutions of the Duffing equation with their phase portraits are proposed and reasoned. It is shown that phase trajectories are initially elliptical and become distorted in the unstable area with the growth of the variable parameter in the damped case....

Feasibility and preliminary outcomes of cognitive-motor training intervention for older working adults reporting subjective cognitive and physical complaints

Cognitive-motor interventions may help preserve and enhance cognitive, physical and sensorimotor function in aging populations, however, their feasibility for older adults working in cognitively demanding positions and experiencing subjective cognitive and physical complaints (SC...
