Integrable spin chains in twisted maximally supersymmetric Yang-Mills theory Open
We study an angular dipole deformation of maximally supersymmetric Yang-Mills theory (SYM) that preserves its classical scale invariance. We show that two-point functions of suitable single trace operators, restricted to an invariant plane…

Gauge theory on twist-noncommutative spaces Open
A bstract We construct actions for four dimensional noncommutative Yang-Mills theory with star-gauge symmetry, with non-constant noncommutativity, to all orders in the noncommutativity. Our construction covers all noncommutative spaces cor…

Quadratic Twist-Noncommutative Gauge Theory Open
Studies of noncommutative gauge theory have mainly focused on noncommutative spacetimes with constant noncommutative structure, with little known about actions for noncommutative 4D Yang-Mills theory beyond this case. We construct an actio…

Two-dimensional O(N)
\n non-linear sigma models are exactly solvable theories and have many applications, from statistical mechanics to their use as QCD toy models. We consider a supersymmetric extension, the non-linear sigma model on the …

Two-dimensional $O(N)$ non-linear sigma models are exactly solvable theories and have many applications, from statistical mechanics to their use as QCD toy models. We consider a supersymmetric extension, the non-linear sigma model on the s…

Effects of nitrogen addition and above-ground biomass removal on the growth and interactions between species of xerothermic grasses Open
Aspects of global change, such as increasing atmospheric nitrogen deposition and changes in land-use, promote the increasing dominance of grass in xerothermic grasslands. It is assumed that nutrient addition and land use affect interaction…

Combining automatic plan integrity check (APIC) with standard plan document and checklist method to reduce errors in treatment planning Open
Purpose/objectives To report our experience of combining three approaches of an automatic plan integrity check (APIC), a standard plan documentation, and checklist methods to minimize errors in the treatment planning process. Materials/met…
