Cystic pancreatic tumors: should we resect all of them?
OBJECTIVE Pancreatic cystic tumors are relatively rare tumors and only 1% of them are malignant. They are often asymptomatic and detected as incidental findings through diagnostic imaging. Currently there are no universal guide lines for the correct clinical approach to pancreatic cystic lesions. Cross-sectional imaging demonstrates some typical morphological features that determine the pre-ope...
متن کاملBringing them all Together
A sequent calculus for hybrid logics is developed from a calculus for classical predicat logic by a series of transformations. We formalize the semantic theory of hybrid logic using a sequent calculus for predicate logic plus axioms. This works, but it is ugly. The unnattractive features are removed one-by-one, until the final vestiges of the metalanguage can be set aside to reveal a fully inte...
متن کاملCo-Büching Them All
We solve the open problems of translating, when possible, all common classes of nondeterministic word automata to deterministic and nondeterministic co-Büchi word automata. The handled classes include Büchi, parity, Rabin, Streett and Muller automata. The translations follow a unified approach and are all asymptotically tight. The problem of translating Büchi automata to equivalent co-Büchi aut...
متن کاملOne to rule them all
The development of transposon-based genome manipulation tools can benefit greatly from understanding transposons' inherent regulatory mechanisms. The Tc1-mariner transposons, which are being widely used in biotechnological applications, are subject to a self-inhibitory mechanism whereby increasing transposase expression beyond a certain point decreases the rate of transposition. In a recent pap...
متن کاملPatient satisfaction following TKA: Bless them all!
Survivorship following modern total knee arthroplasty (TKA) is good with revision rates generally lower than for total hip arthroplasty (THA). Our experience in Belfast supports that fact with original component survivorship of 99% for the low contact stress rotating platform TKA, which is better than our THA survivorship. It is important to discriminate between survivorship and patient satisfa...
