Measurement of jet-substructure observables in top quark, W boson and light jet production in proton-proton collisions at √s=13 TeV with the ATLAS detector

A measurement of jet substructure observables is presented using data collected in 2016 by the ATLAS experiment at the LHC with proton-proton collisions at s√ = 13 TeV. Large-radius jets groomed with the trimming and soft-drop algorithms are studied. Dedicated event selections are used to study jets produced by light quarks or gluons, and hadronically decaying top quarks and W bosons. The observables measured are sensitive to substructure, and therefore are typically used for tagging large-radius jets from boosted massive particles. These include the energy correlation functions and the N-subjettiness variables. The number of subjets and the Les Houches angularity are also considered. The distributions of the substructure variables, corrected for detector effects, are compared to the predictions of various Monte Carlo event generators. They are also compared between the large-radius jets originating from light quarks or gluons, and hadronically decaying top quarks and W bosons

Genetic Risk: The New Frontier for the Duty to Warn

Mental health professionals usually think of the “duty to warn” in the context of mental illness. However, two state appellate courts have endorsed a duty to warn when children of a patient may be at risk genetically for acquiring the disease of their parents. In these cases, the courts held that a physician\u27s legal obligations extended beyond his or her patient to the patient\u27s children. This article discusses these cases, as well as issues regarding implementation of such a duty and the implications for the physician–patient relationship in a health care environment that will be dominated increasingly by genetics issues. The article concludes that it is premature to apply a duty to warn to the treatment of mental illness and to concerns regarding future criminal behavior
