Perturbed Gauged WZNW Models

, 1994
We discuss a new type of unitary perturbations around conformal theories inspired by the $\sigma$-model perturbation of the nonunitary WZNW model. We show that the nonunitary level $k$ WZNW model perturbed by its sigma model term goes to the unitary ...

GAUGED HETEROTIC SIGMA-MODELS [PDF]

Modern Physics Letters A, 1994
The gauging of isometries in general sigma-models which include fermionic terms which represent the interaction of strings with background Yang-Mills fields is considered. Gauging is possible only if certain obstructions are absent. The quantum gauge anomaly is discussed, and then the (1, 0) supersymmetric generalization of the gauge action given.

TRPM4 contributes to cell death in prostate cancer tumor spheroids, and to extravasation and metastasis in a zebrafish xenograft model system

Molecular Oncology, EarlyView.
Transient receptor potential melastatin‐4 (TRPM4) is overexpressed in prostate cancer (PCa). Knockout of TRPM4 resulted in reduced PCa tumor spheroid size and decreased PCa tumor spheroid outgrowth. In addition, lack of TRPM4 increased cell death in PCa tumor spheroids.

Moduli spaces of instantons in flag manifold sigma models. Vortices in quiver gauge theories

Journal of High Energy Physics
In this paper, we discuss lumps (sigma model instantons) in flag manifold sigma models. In particular, we focus on the moduli space of BPS lumps in general Kähler flag manifold sigma models. Such a Kähler flag manifold, which takes the form U n 1 + ⋯ + n

Cystatin A promotes the antitumor activity of T helper type 1 cells and dendritic cells in murine models of pancreatic cancer

Molecular Oncology, EarlyView.
Pancreatic ductal adenocarcinoma (PDAC) is a disease with very poor prognosis due to therapeutic limitations. We investigated the antitumor effects of cystatin A (CSTA) in PDAC murine models. We are first to confirm that CSTA enhances T helper type 1‐mediated antitumor effects through promotion of dendritic cells and M1 macrophage activity. CSTA can be

Integrable sigma model with generalized F structure, Yang-Baxter sigma model with generalized complex structure and multi-Yang-Baxter sigma model

Nuclear Physics B
We construct an integrable sigma model with a generalized F structure, which involves a generalized Nijenhuis structure J satisfying J3=−J. Utilizing the expression of the generalized complex structure on the metric Lie group manifold G in terms of ...

Topological Massive Sigma Models

, 1994
In this paper we construct topological sigma models which include a potential and are related to twisted massive supersymmetric sigma models. Contrary to a previous construction these models have no central charge and do not require the manifold to admit

A topological gauged sigma-model [PDF]

Advances in Theoretical and Mathematical Physics, 2005
We describe a topological field theory that studies the moduli space of solutions of the symplectic vortex equations. It contains as special cases the topological sigma-model and topological Yang-Mills over Kahler surfaces. The correlation functions of the theory are closely related to the recently introduced Hamiltonian Gromov-Witten invariants.
