Induced and Effective Gravity Theories in D=2

, 1993
As a preparation for the study of {\it arbitrary} extensions of $d=2$ gravity we present a detailed investigation of $SO(N)$ supergravity. By gauging a chiral, nilpotent subgroup of the $OSp(N|2)$ Wess-Zumino-Witten model we obtain an all order ...

The pi-N Sigma term - an evaluation using staggered fermions

, 1993
A lattice calculation of the pi-N sigma term is described using dynamical staggered fermions. Preliminary results give a sea term comparable in magnitude to the valence term.Comment: Latex article, 3 pages. Contribution to the LAT93 Conference (Dallas,

Indebted Abbots: The Impact of Lordly Demand on the Late Medieval Rural Economy in Northeast Scotland

Jahrbuch für Wirtschaftsgeschichte
Scottish historiography often describes late medieval Scotland as experiencing socio-economic stagnation while at the same time witnessing a shift from feudal to post-feudal lordship. This paper reevaluates that interpretation through a case study of the

Vector Induced Lattice Gauge Theories

, 1993
We consider vector induced lattice gauge theories, in particular we consider the QED induced and we show that at negative temperature corresponds to the dimer problem while at positive temperature it describes a gas of branched polymers with loops.

The immortal strand hypothesis: still non-randomly segregating opinions

Biomolecular Concepts, 2012
Cairns first suggested a mechanism for protecting the genomes of stem cells (SCs) from replicative errors some 40 years ago when he proposed the immortal strand hypothesis, which argued for the inheritance of a so-called immortal strand by an SC ...

Notes on $WGL_n$-Algebras and Quantum Miura Transformation

, 1993
We start from the quantum Miura transformation [7] for the $W$-algebra associated with $GL(n)$ group and find an evident formula for quantum L-operator as well as for the action of $W_l$ currents (l=1,..,n) on elements of the completely degenerated n ...
