Quantitative criteria characterizing the time change pattern of total lipid-peroxidation carbonyls
Scientific Reports, 2022 The present study introduced for the first time a sigmoidal function regarding the change in lipid-peroxidation carbonyls over time, providing a number of helpful kinetic parameters to more reliably evaluate the secondary oxidation of lipid systems.

Energies, 2021 The focus of this work is to computationally obtain an optimized neural network (NN) model to predict battery average Nusselt number (Nuavg) data using four activations functions. The battery Nuavg is highly nonlinear as reported in the literature, which

Nuclear Engineering and Technology, 2021 High levels for noise and a loss of true signal make the quantitative interpretation of nuclear medicine (NM) images difficult. An application of profile optimization using a sigmoidal function in this study was used to acquire the NM images with high ...

Sigmoid neural transfer function realized by percolation
Optics Letters, 1996 An experiment using the phenomenon of percolation has been conducted to demonstrate the implementation of neural functionality (summing and sigmoid transfer). A simple analog approximation to digital percolation is implemented. The device consists of a piece of amorphous silicon with stochastic bit-stream optical inputs, in which a current percolating ...

Approximation by Superpositions of a Sigmoidal Function
Zeitschrift für Analysis und ihre Anwendungen, 2003 We generalize a result of B. Gao and Y. Xu [J. Math. Anal. Appl. 178 (1993) 221–226] concerning the approximation of functions of bounded variation by linear combinations of a fixed sigmoidal function to the class of functions of bounded f-variation. Also, in the case of one variable, a proposition of A. R. Barron [IEEE Trans. Inf. Theory 36 (1993) 930–

Spatial Scale Dependence of Tropical Cyclone Damage Function: Evidence From the Mainland of China
Earth's Future, 2023 Tropical cyclone (TC) damage function (DF) is widely used to model TC‐event level damage and thus assess the TC risk for a country or region. The scalability of these DFs at more localized scales, such as the province scale, has not been systematically ...

Sigmoidal dynamics of macro-financial leverage
Quantitative Finance and Economics, 2023 Logistic sigmoids due to their flexibility seem to be natural candidates for modelling macrofinancial leverage behavior. The sigmoidal leverage transition towards its stationary value, which was driven by the yield spreads, could have replicated the ...
