This paper introduces state polynomials, i.e., polynomials in noncommuting variables and formal states of their products. A state analog of Artin’s solution to Hilbert’s 17th problem is proved s...
阅读全文For the incompressible Euler flows in planar bounded domains $\Omega$, we prove that the vortex concentrating at the harmonic center of $\Omega$ causes the existence of vortexes with small vortici...
阅读全文In this paper, noting that the prediction of time series follows the temporal order of data, we propose a frequentist model averaging method based on forward-validation. Our method also considers ...
阅读全文This paper focuses on the minimization of a possibly nonsmooth objective function over the Stiefel manifold. The existing approaches either lack efficiency or can only tackle prox-friendly objecti...
阅读全文Two-phase flow with moving contact lines (MCLs) is an unsolved problem in fluid dynamics. It is challenging to solve the problem numerically due to its intrinsic multiscale property that the micro...
阅读全文Proportional–integral–derivative (PID) controller is the most widely used form of feedback control by far. However, a satisfactory theory is still lacking to explain the rationale of the widespr...

阅读全文Reconstructions of a material sample from a sparse set of projection data using TomoCAM, conventional MBIR, and direct approximation methods. TomoCAM delivers higher-quality reconstructions compared t...
阅读全文During training, only the parameters of the generator are transmitted between the central server and local devices. The discriminators on the local devices update their regularization terms based on t...
阅读全文"The algorithm can use disease genes to identify in which tissues, for example in the heart, similar genes are particularly frequently expressed, which then lead to a disease. It can predict whether a...
