Hermitian Yang–Mills Connections on Blowups
Consider a vector bundle over a Kähler manifold which admits a Hermitian Yang-Mills connection. We show that the pullback bundle on the blowup of the Kähler manifold at a collection of points also admits a Hermitian Yang-Mills...

Yang-Mills as massive Chern-Simons theory
The Yang-Mills (YM) equation in three spacetime dimensions (3D) can be modified to include a novel parity-preserving interaction term, with an inverse mass parameter, in addition to a possible topological mass term. The novelty...

Inverse Problem for the Yang–Mills Equations
Abstract: We show that a connection can be recovered up to gauge from source-to-solution type data associated with the Yang–Mills equations in Minkowski space R1+3. Our proof analyzes the principal symbols of waves generated by...

The Gluon Green's function in N=4 supersymmetric Yang-Mills theory.
The high energy limit of scattering amplitudes in the N = 4 supersymmetric Yang– Mills theory is studied by solving the corresponding BFKL equation in the next– to–leading approximation. The gluon Green’s function is analysed...
Twistors, the ASD Yang-Mills equations and 4d Chern-Simons theory
Abstract We show that the approaches to integrable systems via 4d Chern-Simons theory and via symmetry reductions of the anti-self-dual Yang-Mills...

Entrance laws at the origin of self-similar Markov processes in high dimensions
In this paper we consider the problem of finding entrance laws at the origin for self-similar Markov processes in Rd, killed upon hitting the origin. Under suitable assumptions, we show the existence of an entrance...

Solvent-assisted programming of flat polymer sheets into reconfigurable and self-healing 3D structures.
It is extremely challenging, yet critically desirable to convert 2D plastic films into 3D structures without any assisting equipment. Taking the advantage of solvent-induced bond-exchange reaction and elastic-plastic transition...

Twisting of a Pristine α-Fe Nanowire
The torsion of pristine α-Fe nanowires was studied by molecular dynamics simulations. Torsion-induced plastic deformation in pristine nanowires is divided into two regimes. Under weak torsion, plastic deformation leads to...

Calibrating the Dice Loss to Handle Neural Network Overconfidence for Biomedical Image Segmentation.
The Dice similarity coefficient (DSC) is both a widely used metric and loss function for biomedical image segmentation due to its robustness to class imbalance. However, it is well known that the DSC loss is poorly calibrated...
