Slingshots and Boomerangs
A “slingshot” proof suggested by Kurt Gödel (1944) has been recast by Stephen Neale (1995) as a deductive argument showing that no non-truthfunctional sentence connective can permit the combined use, within its scope, of two truth-functionally valid inference principles involving definite descriptions. According to Neale, this result provides indirect support for Russell’s Theory of Description...
متن کاملReconstruction of the Neutrino Mixing Matrix and Leptonic Unitarity Triangles from Long-baseline Neutrino Oscillations
We derive a new set of sum rules between the neutrino mass and mixing parameters in vacuum and their effective counterparts in matter. The moduli of nine genuine lepton mixing matrix elements can then be calculated in terms of the matter-corrected ones, and the latter can directly be determined from a variety of long-baseline neutrino oscillations. We show that it is possible to reconstruct the...
متن کاملDidgeridoos, songs and boomerangs for asthma management.
ISSUE ADDRESSED In Australia, asthma is more prevalent among Indigenous than non-Indigenous people. Awareness of asthma and compliance with management plans are poor, as is engagement with health services in general. The study explored whether offering culturally appropriate music lessons could enhance asthma awareness and engagement to improve asthma and general wellbeing. METHODS Two studie...
متن کاملNew and improved results for packing identical unitary radius circles within triangles, rectangles and strips
The focus of study in this paper is the class of packing problems. More specifically, it deals with the placement of a set of N circular items of unitary radius inside an object with the aim of minimizing its dimensions. Differently shaped containers are considered, namely circles, squares, rectangles, strips and triangles. By means of the resolution of nonlinear equations systems through the N...
متن کاملLeptonic and semi - leptonic B decays
We present results for the semi-leptonic and leptonic decays of B mesons. These non-perturbative matrix elements are important for constraining the CKM matrix. Results are presented for the pseudoscalar and vector decay constants, as well as flavour breaking ratios and heavy quark symmetry relations. We consider the chiral and momentum dependence of the semi-leptonic form factors of the decay B...
