表征PINN中可能的失败模式。本文的思路也比较简单,通过对PINN的优化域进行观察,发现导致PINN训练的原因并不是因为神经网络的表达力不足,而是由于PINN中引入了基于PDE微分算子的软正则化约束(也就是残差项),这导致了许多微妙的问题,使得问题病态。简单的事,是由于PINN的设置,导致了一个极度凹凸不平不平滑的优化域,使...

Furthermore, it is demonstrated that AE allows for the localization of active cracks, quantification of the damage accumulation under increasing stresses, and characterization of the dominant crack bridging mechanisms and failure modes observed in the different types of SHCC....
Third, the preterm study population was representative of survivors of modern neonatal intensive care in terms of gestational age range and prevalence of co-morbidities of preterm birth that may influence brain maturation, but it is still possible that the results were influenced by biological variabil...
In other words, due to the internal interaction between the pressure waves, it is possible that the lymphatic endothelial cells experienced high shear disturbances. Given that WSS has been hypothesized to be an important mechanical regulator in assisting the control of lymphatic contraction, the noisy...
It is possible that the bridging water molecule exists directly after ATP hydrolysis, in the ‘early’ ADP·Pi state, to be replaced by the Mg2+ itself in the ‘late’ ADP·Pi state, which is captured by cryo-EM. e, The X-ray structure of ATPγS-bound p9729 was used as a ...

Considering all 33 daily periods (over 27 calendar days) where comparisons were possible, in 14 cases the value of Ra2dj was >0.5. In the remaining cases the Ra2dj was lower; however, the Ra2dj values do not always reflect the close tracking of PM2.5 levels across communities. This ...
Most notably, through a single study of the pocketome, hundreds of binding sites are analyzed in detail, obtaining possible drug associations for the entire set of promising targets in Mtb, as described in the following sections. To the best of our knowledge, this is the first study that ...
Configuration theory assumes that the characteristics of objects fall into coherent patterns and can be categorized within a set of possible configurations rather than analyzed in isolation. In this way, existing SES could be applied to our taxonomy, analyzing characteristics and coherent patterns and ...
