• A generalization of the self-mutual helicity decomposition to open magnetic fields. Derived expressions can be readily used analyse complex MHD simulations. The topological underpinning fields connected a planar boundary is naturally described by field line winding. This observation leads definition winding , which closely related more commonly calculated relative . Winding helicity, however,...

We find that fund managers who began their careers during recessions produce superior returns. This performance is not unconditional, as they exhibit better market timing than non-recession counterparts in recessions, but do demonstrate stock picking booms. Exploring managers' portfolio choices across years, we recession tilt investments towards defensive, rather cyclical, industries and before...

This Article explores the phenomenon of “mutual deference” between medical and legal systems to show that placing mandated reporting responsibilities on clinicians results in lasting harm for families. On side, are obligated defer any “reasonable suspicion” a child may be at risk system; their concern mild or severe, nonmedical nature. But system, comprised lay-people field medicine, is illequi...
