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...
Multifunctional peptide-assembled micelles for simultaneously reducing amyloid-β and reactive oxygen species.
The excessive production and deposition of amyloid-β (Aβ) is one of the most important etiologies of Alzheimer's disease (AD). The interaction between Aβ and metal ions produces aberrant reactive oxygen species (ROS), which...
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...
Numerical simulations of oil spill trajectories in the Danjiangkou Reservoir in China
Oil spills in surface water happen each year in the world and significantly damage water quality and ecosystems. Numerical simulation of oil spill trajectories is helpful for risk assessment and risk controlling. Previous...
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...

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...
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...

Insights into the Origin of High Activity of Ni5P4(0001) for Hydrogen Evolution Reaction.
Hydrogen evolution reaction (HER) is directly relevant to green hydrogen production from water splitting. Recently, a low-cost Ni5P4 material has been demonstrated experimentally and theoretically to exhibit excellent...
Design and Characterization of a Novel Core–Shell Nano Delivery System Based on Zein and Carboxymethylated Short-Chain Amylose for Encapsulation of Curcumin
Zhiwei Lin, Linjie Zhan, Kaili Qin, Yang Li, Yang Qin, Lu Yang, Qingjie Sun, Na Ji, Fengwei Xie
Jun 11, 2024
Curcumin is a naturally occurring hydrophobic polyphenolic compound with a rapid metabolism, poor absorption, and low stability, which severely limits its bioavailability. Here, we employed a starch–protein-based nanoparticle...
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...

Audio Tampering Forensics Based on Representation Learning of ENF Phase Sequence
This paper proposes an audio tampering detection method based on the ENF phase and BI-LSTM network from the perspective of temporal feature representation learning. First, the ENF phase is obtained by discrete Fourier transform...

Calibrating the Dice Loss to Handle Neural Network Overconfidence for Biomedical Image Segmentation.
Michael Yeung, Leonardo Rundo, Yang Nan, Evis Sala, Carola-Bibiane Schönlieb, Guang Yang
Mar 25, 2023
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...
Pharmacogenomics and the Yin/Yang actions of ginseng

Jun 16, 2011
In Chinese medicine, ginseng (Panax ginseng C.A. Meyer) has long been used as a general tonic or an adaptogen to promote longevity and enhance bodily functions. It has also been claimed to be effective in combating stress...
