Based on the Gerstenhaber Theory it is clarified how operadic dynamics may be introduced. Operadic observables satisfy the Gerstenhaber algebra identities and their time evolution is governed by the Gerstenhaber-Lax or Gerstenhaber-Heisenberg equation. In this way one can describe classical and quantum time evolution of operations. The notion of an operadic Lax pair is introduced as well.

Automatic Dependent Surveillance-Broadcast (ADS-B) is an emerging software-defined radar technology that is supposed to replace current standards and is part of the Next Generation Transportation Systems (NextGen) in the US. In spite of its several benefits, this technology has been widely cited for being designed without security in mind, making it vulnerable to numerous attacks. Most approach...

BACKGROUND Despite concerns that facilitating informed choice would decrease diabetes screening uptake, 'informed choice' invitations that increased knowledge did not affect attendance (the DICISION trial). We explored possible reasons using data from an experimental analogue study undertaken to develop the invitations. We tested a model of the impact on knowledge, attitude and intentions of a ...

BACKGROUND Women's beliefs and representations of breast cancer (BC) and breast screening (BS) are salient predictors for BS practices. This study utilized the health belief model (HBM) and common-sense model (CSM) of illness self-regulation to explore factors associated with BS uptake in Malta and subsequently, to identify the most important predictors to first screening uptake. METHODS This...

OBJECTIVES To test the hypothesis that prenatal multiple micronutrient supplementation (MMS) and an early invitation to food supplementation would increase maternal hemoglobin level and birth weight and decrease infant mortality, and to asses...
