Four scenarios

Four - Neutrino Scenarios ∗

The main features of four-neutrino 3+1 and 2+2 mixing schemes are reviewed, after a discussion on the necessity of at least four massive neutrinos if the solar, atmospheric and LSND anomalies are due to neutrino oscillations.

Telling Three from Four Neutrino Scenarios

In this talk I will consider the possibility of distinguish the usual three neutrino model from scenarios in which a light sterile neutrino is also present. I will show that the confusion with the so-called 3+1 scheme can arise in some particular region of the parameter space whereas it is essentially absent for the 2+2 scheme. Then I will discuss the ambiguities in the determination of the CP-...

Unusual false-positive results of whole-body 131I scintigraphy: Four different case scenarios

Post-treatment or diagnostic whole-body radioiodine scintigraphy is widely used to assess the residual, recurrence, or metastases of differentiated thyroid carcinoma because of the high sensitivity and accuracy that this assessment provides. While bearing in mind all the diagnostic potential of this test, we have to consider its’ potential pitfalls, as well. Herein, we present 4 patients with d...

Four scenarios for adoption of cloud computing in china

Selecting appropriate technology strategy is crucial to those designing ICT-based offering for specific geographical market. The antecedents of adopting particular technology can be used to identify opportunities and barriers of entry, but further information is needed for technology management on how adoption would take place. In this paper, it is argued that deploying a scenario method facili...
