A theoretical framework for exploring the effect of the Six Sigma management activities on corporate competitiveness [PDF]

, 2011
Six Sigma has long been used as an effective way to restructure a company’s management process. While there are abundant case study literatures on Six Sigma, a theoretical framework that can logically advance the previous work into a higher level is ...

Dualization of the principal sigma model [PDF]

Journal of Mathematical Physics, 2008
The first-order formulation of the principal sigma model with a Lie group target space is performed. By using the dualization of the algebra and the field content of the theory the field equations which are solely written in terms of the field strengths are realized through an extended symmetry algebra parametrization.

Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining

Molecular Oncology, EarlyView.
IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

$$\overline{\Sigma }^{\pm }$$ Σ ¯ ± production in $$\text {pp}$$ pp and $$\text {p}{-}\text {Pb}$$ p - Pb collisions at $$\sqrt{s_{\textrm{NN}}} = 5.02$$ s NN = 5.02  TeV with ALICE

European Physical Journal C: Particles and Fields
The transverse momentum spectra and integrated yields of anti- $$\Sigma $$ Σ hyperons ( $$\overline{\Sigma }^{\pm } $$ Σ ¯ ± ) have been measured in $$\text {pp}$$ pp and $$\text {p}{-}\text {Pb}$$ p - Pb collisions at $$\sqrt{s_{\textrm{NN}}}=5.02$$ s ...

ON RENORMALIZATION OF POISSON–LIE T-PLURAL SIGMA MODELS

Acta Polytechnica, 2013
Covariance of the one-loop renormalization group equations with respect to Poisson–Lie T-plurality of sigma models is discussed. The role of ambiguities in renormalization group equations of Poisson–Lie sigma models with truncated matrices of parameters ...

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

Molecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Vacua, walls and junctions in GNF,NC

Nuclear Physics B, 2019
We discuss vacua, walls and three-pronged junctions of the mass-deformed nonlinear sigma models on the Grassmann manifold GNF,NC=SU(NF)SU(NC)×SU(NF−NC)×U(1), which are non-Abelian gauge theories for NC≥2. Polyhedra are proposed in [1] to describe Bogomol'

Finding novel vulnerabilities of hypomorphic BRCA1 alleles

Molecular Oncology, EarlyView.
Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have

Supersymmetric Poisson and Poisson-supersymmetric sigma models

Journal of High Energy Physics
We revisit and construct new examples of supersymmetric 2D topological sigma models whose target space is a Poisson supermanifold. Inspired by the AKSZ construction of topological field theories, we follow a graded-geometric approach and identify two ...

Yang–Baxter sigma models based on the CYBE

Nuclear Physics B, 2015
It is known that Yang–Baxter sigma models provide a systematic way to study integrable deformations of both principal chiral models and symmetric coset sigma models.
