Obligations in Classical Procedure

A Uniform Proof Procedure for Classical and Non-Classical Logics

G. Görz & S. Hölldobler, eds. KI-96: Advances in Artificial Intelligence, LNAI 1137, pp. 307–319, c ©Springer Verlag, 1996. Abstract. We present a proof procedure for classical and non-classical logics. The proof search is based on the matrix-characterization of validity where an emphasis on paths and connections avoids redundancies occurring in sequent or tableaux calculi. Our uniform path-che...

Co-national Obligations & Cosmopolitan Obligations towards Foreigners

On Obligations

Access control is concerned with granting access to sensitive data based on conditions that relate to the past or present, so-called provisions. Expressing requirements from the domain of data protection necessitates extending this notion with conditions that relate to the future. Obligations, in this sense, are concerned with commitments of the involved parties. At the moment of granting acces...

A Paraconsistent Proof Procedure Based on Classical Logic. Extended Abstract

Apparently Ex Falso Quodlibet (or Explosion) cannot be isolated within CL (Classical Logic); if Explosion has to go, then so have other inference rules, for example either Addition or Disjunctive Syllogism. This certainly holds according to the standard abstract view on logic. However, as I shall show, it does not hold if a logic is defined by a procedure—a set of instructions to obtain a proof...

Total proximal anastomosis detachment after classical bentall procedure

INTRODUCTION Since its introduction in 1968, the Bentall procedure has been the primary surgical solution for aneurysms of the aortic root. However, many surgeons have reported serious procedural complications such as detachment of coronary ostia and pseudoaneurysm formation at anastomosis sites. Therefore, the Bentall procedure has undergone several modifications to eliminate those complicatio...
