    On the nature of the stretched exponential photoluminescence decay for silicon nanocrystals by Cardin J, Gourbilleau F, Zatryb G, Podhorodecki A, Misiewicz J

    Published 2011-01-01
    “…It was found that photoluminescence decay is strongly non-single exponential and can be described by the stretched exponential function. It was also shown that effective decay rate probability density function may be recovered by means of Stehfest algorithm. …”

    The Ageing of μPlasma-Modified Polymers: The Role of Hydrophilicity by Chang Che, Behnam Dashtbozorg, Shaojun Qi, Matt J. North, Xiaoying Li, Hanshan Dong, Michael J. Jenkins

    Published 2024-03-01
    “…The ageing process over five hours was modelled using a modified stretched exponential function Kohlrausch–Williams–Watts (KWW) model, and it was found that the ageing rate was dependent on the hydrophilicity of polymers, with polyamides ageing more rapidly than polyethylene.…”

    Emergent invariance and scaling properties in the collective return dynamics of a stock market. by Hideyuki Miyahara, Hai Qian, Pavan S Holur, Vwani Roychowdhury

    Published 2024-01-01
    “…In particular, we consider the pairwise (between stocks i, j) partial correlations of returns with respect to the market mode, ci,j(τ), (thus, correcting for the baseline return behavior of the market), over different time horizons (τ), and discover two novel emergent phenomena: (i) the standardized distributions of the ci,j(τ)'s are observed to be invariant of τ ranging from from 1000min (2.5 days) to 30000min (2.5 months); (ii) the scaling of the standard deviation of ci,j(τ)'s with τ admits good fits to simple model classes such as a power-law τ-λ or stretched exponential function [Formula: see text] (λ, β > 0). …”

    Interfacial Spin Glass State and Exchange Bias in the Epitaxial La0.7Sr0.3MnO3/LaNiO3 Bilayer by Guo-wei Zhou, Xiao-fen Guan, Yu-hao Bai, Zhi-yong Quan, Feng-xian Jiang, Xiao-hong Xu

    Published 2017-05-01
    “…Moreover, a strong spin glass state has been observed at the LSMO/LNO interface, which is further confirmed by two facts: first, that the dependence of the irreversible temperature on the cooling magnetic field follows the Almeida-Thouless line and, second, that the relaxation of the thermal remnant magnetization can be fitted by a stretched exponential function. Interestingly, we also find an exchange bias effect at the LSMO/LNO bilayer below the spin glass freezing temperature, indicating that the exchange bias is strongly correlated with the spin glass state at its interface.…”

    The Complex Structure of the Pharmacological Drug–Disease Network by Irene López-Rodríguez, Cesár F. Reyes-Manzano, Ariel Guzmán-Vargas, Lev Guzmán-Vargas

    Published 2021-08-01
    “…We find that the connectivities between drugs (outgoing links) and diseases (incoming links) follow approximately a stretched-exponential function with different fitting parameters; for drugs, it is between exponential and power law functions, while for diseases, the behavior is purely exponential. …”
