Institutional efforts in the U.S. to develop a conceptual framework for business enterprises can be traced to the Paton and Littleton monograph in 1940 and later to the two Accounting Research Studies by Moonitz and Sprouse in 1962-1963. A committee of the American Accounting Association issued an influential report in which it advocated a “decision usefulness” approach in 1966, which was carri...

The SO(32) heterotic string can be obtained from the type IIB string by gauging a discrete symmetry that acts as (−1) FL on the perturbative string states and reverses the parity of the D-string. Consistency requires the presence of 32 NS 9-branes – the S-duals of D9-branes – which give SO(32) Chan-Paton factors to open D-strings. At finite string coupling, there are SO(32) charges tethered to ...

We show that the N = 2 open string describes a theory of self-dual Yang Mills (SDYM) in (2, 2) dimensions. The coupling to the closed sector is described by SDYM in a Kähler background, with the Yang-Mills fields providing a source term to the self-duality equation in the gravity sector. The four-point S-matrix elements of the theory vanish, so the tree-level unitarity constraints leading to th...

The anterior tibial syndrome is well known. It was described by Vogt in 1943 and numerous reports have since been published (Horn 1945; Hughes 1948; Carter, Richards and Zachary 1949; Blandy and Fuller 1957; Paton 1968). The etiology of the condition remains obscure but the clinical features are well recognised : gradually increasing pain in the muscles of the anterior tibial compartment, begin...

We discuss two inequivalent ways for describing magnetized D-branes wrapped N times on a torus T 2. The first one is based on a non-abelian gauge bundle U(N), while the second one is obtained by means of a Narain T-duality transformation acting on a theory with non-magnetized branes. We construct in both descriptions the boundary state and the open string vertices and show that they give rise t...

We propose a new Lagrangian describing N = 4 superconformal field theory in three dimensions. This theory describes interacting field theory on the worldvolume of a M2brane on an orbifold, and is obtained as a Z2-quotient of the theory proposed by Bagger and Lambert. Despite unusual Chan-Paton structures, we can take Z2-orbifold by using SU(2) × SU(2) bifundamental representations. We also anal...
