FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Calabi-Yau CFTs and random matrices
Journal of High Energy Physics, 2022 Using numerical methods for finding Ricci-flat metrics, we explore the spectrum of local operators in two-dimensional conformal field theories defined by sigma models on Calabi-Yau targets at large volume.

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Overdetermined Systems, Conformal Differential Geometry, and the BGG Complex [PDF]
, 2008 This is an expanded version of a series of two lectures given at the IMA summer program “Symmetries and overdetermined systems of partial differential equations”. The main part of the article describes the Riemannian version of the prolongation procedure for certain overdetermined systems obtained recently in joint work with T.P. Branson, M.G. Eastwood,

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Q-Curvature, Spectral Invariants, and Representation Theory
Symmetry, Integrability and Geometry: Methods and Applications, 2007 We give an introductory account of functional determinants of elliptic operators on manifolds and Polyakov-type formulas for their infinitesimal and finite conformal variations.

Geometric classification of 4d N=2 $$ \mathcal{N}=2 $$ SCFTs
Journal of High Energy Physics, 2018 The classification of 4d N=2 $$ \mathcal{N}=2 $$ SCFTs boils down to the classification of conical special geometries with closed Reeb orbits (CSG). Under mild assumptions, one shows that the underlying complex space of a CSG is (birational to) an affine

Poincare-Einstein Holography for Forms via Conformal Geometry in the Bulk [PDF]
, 2012 We study higher form Proca equations on Einstein manifolds with boundary data along conformal infinity. We solve these Laplace-type boundary problems formally, and to all orders, by constructing an operator which projects arbitrary forms to solutions. We
