Osmium diffusion rates in sulfides are fast (10−13.5 m2 s−1 at 1,000 °C) and full isotopic resetting can occur in grains up to 500 µm at such conditions in 0.01 year (ref. 73). Therefore, even if the sublithospheric sulfide was protogenetic, Re–Os isotope ...

The diffusion models tend to be tested individually in isolation and remain the same over time for the studied innovations in the literature. Moreover, there is growing interest to learn from other countries in our current age of globalization. Therefore, this paper chooses the innovation of ...
Tannock and others suggested a strong correlation between effective oxygen diffusion distances and the decrease in growth fraction and, ultimately, necrosis. More recent findings demonstrated that not only lack of oxygen, but also lack of glucose can lead to a decrease in the growth fraction, and ...
It has been suggested that carbonation of concrete can be modeled using a simplification of Fick's second law of diffusion (Lagerblad, 2006), which states that the depth of carbonation is proportional to the square root of time. Depending on the characteristics of the concrete and the ambient...
are not explicitly discussed. The main theme of the paper is to interpret the observations in terms of the existing modulation theories. The theoretical model describes the propagation of cosmic rays in the interplanetary medium in terms of diffusion, convection, and energy changes. The topic is ...
Moreover, we use the cycle symmetry to study the circulation fluctuations for diffusion processes on the circle. We prove that the empirical circulations of the forward and backward cycles satisfy a large deviation principle with a rate function which has a highly non-obvious symmetry. Extensions ...

In this paper, we present a novel diffusion model-based monaural speech enhancement method. Our approach incorporates the separate estimation of speech spectra's magnitude and phase in two diffusion networks. Throughout the diffusion process, noise clips from real-world noise interferences are added ...
Yuan (1999) preliminarily estimated the amount of atmospheric CO2 uptake by surface karst processes as 0.22–0.608 Pg C/a globally, using standard limestone tablet method, hydrochemical-runoff method and diffusion boundary method, accounting for about 10%–25% of the global “missing sink”. Li ...
