Oppositional defiant disorder (ODD) consists of an enduring pattern of uncooperative, defiant and hostile behaviour toward authority figures that does not involve major antisocial violations and is not accounted for by the developmental stage of the child. The rate of ODD in children and adolescents in the general population has been reported to be between 2% and 16%. The International Classifi...

Strong-field laser-atom interactions provide extreme conditions that may be useful for investigating the de Broglie-Bohm quantum interpretation. Bohmian trajectories representing bound electrons in individual atoms exhibit both even and odd harmonic motion when subjected to a strong external laser field. The phases of the even harmonics depend on the random initial positions of the trajectories...

In the world with axion the precise measurement of gravitational force and check of the equivalence principle at small distances, λ ∼ 1cm and less, could provide an additional test of CP symmetry. Using the chiral approach, we connect the strength of CP-odd axion-nucleon vertex with CP-odd pion-nucleon coupling for color electric dipole moments of quarks as a low energy source of CP violation. ...

BACKGROUND We examine models of the relationship between oppositional defiant disorder (ODD) and conduct disorder (CD) in a community sample. Particular attention is paid to the generalisability of findings based on clinic-referred boys. METHODS The analyses were based on four waves of data from the Great Smoky Mountains Study covering children in the community aged 9-16 years. Child and pare...
