Group-invariant solutions of semilinear Schrodinger equations in multi-dimensions

Symmetry group methods are applied to obtain all explicit group-invariant radial solutions to a class of semilinear Schr¨odinger equations in dimensions n = 1. Both focusing and defocusing cases of a power nonlinearity are considered, including the special case of the pseudo-conformal power p = 4/n relevant for critical dynamics. The methods involve, first, reduction of the Schr¨odinger equations to group-invariant semilinear complex 2nd order ordinary differential equations (ODEs) with respect to an optimal set of one-dimensional point symmetry groups, and second, use of inherited symmetries, hidden symmetries, and conditional symmetries to solve each ODE by quadratures. Through Noether’s theorem, all conservation laws arising from these point symmetry groups are listed. Some group-invariant solutions are found to exist for values of n other than just positive integers, and in such cases an alternative two-dimensional form of the Schr¨odinger equations involving an extra modulation term with a parameter m = 2−n = 0 is discussed.

The Dynamic Interplay of Attachment and Temperament in Relation to Dimensions of Aggression

The current study examined whether overt and relational forms of reactive and proactive aggression were differentially related to adolescents’ temperament and attachment security. Measures of adolescents’ temperament, attachment security, and aggression were completed by 211 adolescents, ages 10–14, and their caregivers. Attachment security was consistently associated with all four dimensions of aggression, whereas proneness to frustration was found to be uniquely associated with reactive-overt aggression. Additionally, it was found that at lower levels of effortful control more secure attachment was related to lower levels of reactive-relational aggression. Results also indicated that, for girls, the relation between attachment and proactive-overt and proactive-relational aggression was only significant when effortful control was low. Conversely, for boys, the relation between attachment and proactive-overt aggression and proactive-relational aggression was significant when effortful control was high. Implications of these findings and limitations to the current study are discussed.

Ethical Dimensions in Paediatric Neurology: A Look into the Future

Les professionnels de la santé et les familles pour qui des enfants qui participent à la recherche en génétique ou qui nécessitent des services génétiques spécialisés, y compris, le dépistage génétique, seront confrontés à des interrogations non seulement médicales, mais sociales, éthiques et juridiques liées à la génétique en neurologie pédiatrique. Les enfants se retrouvent souvent au centre d’innovations dans le cadre de recherches en génétique et leurs besoins uniques soulèvent des inquiétudes quant aux risques et aux bénéfices associés à cette recherche. Plus précisément, le consentement, l’utilisation de base de données génétique et la thérapie génique soulèvent des enjeux particuliers. En plus de ces enjeux, des risques psychologiques peuvent aussi leur être associés. À la lumière de l’analyse de lignes directrices nationales et internationales, il sera question, dans cet article, des bénéfices et de l’impact des technologies génétiques chez l’enfant. Les médecins, les législateurs et les familles doivent être informés de ces lignes directrices et doivent comprendre les enjeux éthiques et psychologiques liés à la génétique en neurologie pédiatrique. // Health care providers and families with children who participate in genetic research or who need specialized genetic services, including genetic testing, will encounter not only medical but difficult social, ethical, and legal questions surrounding pediatric genetic neurology. Children are often at the center of much of the genetic revolution and their unique needs raise special concerns about the risks and the benefits associated with genetic research, particularly the issues of consent, the use of genetic databases, and gene therapy. Moreover, genetic research and testing raise important psychosocial risks. In this article we discuss some of the benefits and consequences of genetic technologies for children in relation to national and international guidelines. In particular, physicians, policy-makers, and families should be knowledgeable about the guidelines and have good understanding of the psychosocial and ethical issues associated with genetics in pediatric neurology.
