On the global $2$-holonomy for a $2$-connection on a $2$-bundle [PDF]
J. Geom. Phys. 117 (2017),151-178, 2015 A crossed module constitutes a strict $2$-groupoid $\mathcal{G}$ and a $\mathcal{G}$-valued cocycle on a manifold defines a $2$-bundle. A $2$-connection on this $2$-bundle is given by a Lie algebra $\mathfrak g$ valued $1$-form $A $ and a Lie algebra $\mathfrak h$ valued $2$-form $B $ over each coordinate chart together with $2$-gauge transformations ...

Cyclooxygenase-2 and the inflammogenesis of breast cancer.
World Journal of Clinical Oncology, 2014 Cohesive scientific evidence from molecular, animal, and human investigations supports the hypothesis that constitutive overexpression of cyclooxygenase-2 (COX-2) is a ubiquitous driver of mammary carcinogenesis, and reciprocally, that COX-2 blockade has

An explicit formula of powers of the $2\times 2$ quantum matrices and its applications [PDF]
arXiv, 2021 We present an explicit formula of the powers for the $2\times 2$ quantum matrices, that is a natural quantum analogue of the powers of the usual $2\times 2$ matrices. As applications, we give some non-commutative relations of the entries of the powers for the $2\times 2$ quantum matrices, which is a simple proof of the results of Vokos-Zumino-Wess ...

Affine sl(2|1) and D(2|1;alpha) as Vertex Operator Extensions of Dual Affine sl(2) Algebras [PDF]
Commun.Math.Phys. 214 (2000) 495-545, 1999 We discover a realisation of the affine Lie superalgebra sl(2|1) and of the exceptional affine superalgebra D(2|1;alpha) as vertex operator extensions of two affine sl(2) algebras with dual levels (and an auxiliary level 1 sl(2) algebra). The duality relation between the levels is (k+1)(k'+1)=1. We construct the representation of sl(2|1) at level k' on

Proceedings of the National Academy of Sciences of the United States of America, 1994 Nonsteroidal antiinflammatory drugs (NSAIDs) are widely used for the treatment of inflammatory diseases, but significant side effects such as gastrointestinal erosion and renal damage limit their use. NSAIDs inhibit the enzyme cyclooxygenase (COX), which

Cyclooxygenase-2-dependent lymphangiogenesis promotes nodal metastasis of postpartum breast cancer.
Journal of Clinical Investigation, 2014 Breast involution following pregnancy has been implicated in the high rates of metastasis observed in postpartum breast cancers; however, it is not clear how this remodeling process promotes metastasis.
