The red curve is a fit to the data using a bi-exponential decay function. The extracted g(2)(0) of 0.181 ± 0.030 is slightly higher than the pulsed measurement due to higher Poissonian background caused by CW excitation. All data were obtained at 11 K temperature. Full size ...
Histograms were fitted by a monoexponential decay function. 4. Discussion The FRET-labeled FOF1-ATP synthase from E. coli with two fluorophores attached to the ε and c-subunits was functional for ATP hydrolysis and ATP synthesis after reconstitution in liposomes. The distances between the ...
Adjust the initialized learning rate and using exponential decay strategy to adjust the learning rate during training process. Using traditional image augmentation function including random crop and random flip to augment the training dataset which protomed the new model performance. I have uploaded a ...
A similar decay constant for current and force as a function of interatomic distance is seen. The blue dashed lines are exponential fits to the data. c, Structural snapshots showing a molecular mechanics simulation of a PTCDA molecule held between a Ag substrate and tip (read right to left)....
[21]. Then the overall behavior of all energy subspaces is a multi- exponential decay and not diffusive, of course. On that account it appears plausible that the diffusive regime be- comes much larger, if only a certain subspace of energy is considered. 7 Summary and Conclusion In this ...
(2)Exponential moving average(EMA) 由于样本的梯度密度是训练时根据batch计算出来的,通常情况下batch较小,直接计算出来的梯度密度可能不稳定,所以采用滑动平均的方式处理梯度计算。我了解到的滑动平均常用于模型的loss优化器,比如SGD,RMSprop,Adam,论文中指出在BatchNormalization中也用到。公式如下所示。
The g2-functions were fitted with a single exponential decaywith the relaxation rate Γ(q) = 1/τc(q), where τc denotes the characteristic relaxation time of the sample. In general, the contrast βcorr should equal the degree of coherence βs of the X-ray beam33,34,35,36 if ...
