Two alternative versions of strangeness

Two alternative versions of strangeness

The concept of strangeness emerged from the low energy phenomenology before the entry of quarks in particle physics. The connection between strangeness and isospin is rather accidental and loose and we recognize later that the definition of strangeness is model-dependent. Indeed, in Gell-Mann's triplet quark model we realize that there is a simple alternative representation of strangeness. When...

Two Versions of Millianism

Quicksort Revisited - Verifying Alternative Versions of Quicksort

We verify the correctness of a recursive version of Tony Hoare’s quicksort algorithm using the Hoare-logic based verification tool Dafny. We then develop a non-standard, iterative version which is based on a stack of pivot-locations rather than the standard stack of ranges. We outline an incomplete Dafny proof for the latter.

Strangeness-changing response functions: an alternative approach to hypernuclear structure

We study strangeness-changing response functions as an alternative description of hypernuclear structure. Hypernuclear states are treated in the same manner as any other conventional nuclear excitation that emerges from the response of the nuclear ground state to an external probe. The nuclear response is calculated using a random-phase approximation to an effective relativistic mean-field mode...

two versions of jāmiʻ al-tamthīl

jāmiʻ al-tamthīlwas written in 11th century ah. by muḥammad ʻalī hablehrūdī. this book is a collection of proverbs, insights and anecdotes and some sermons associated with them. there are a lot of manuscripts of this book in different libraries all over the world. the authors have found two different forms of writing through their critical corrections. although both forms are generally similar,...
