Soils, weathering zones, and landscapes in the upland loess of Tama and Grundy counties, Iowa

“…More specifically, this area includes parts of sections 24, 25, and 36, T86N, R13W, Tama County, Iowa. Alden and Leighton (1917) described the lowan drift plain as a drift-mantled erosional topography. They attributed lack of accordance in the lowan area to unequal mantling of a rela tively fresh drift on Kansan gumbotil.…”

“…^The eight counties whose values were used include Black Hawk, Bremer, Buchanan, Butler, Chickasaw, Floyd, Howard, and Mitchell. Alden and Leighton (1917) considered that about one to two feet of loess mantled the majority of the lowan drift plain except in a few southern counties and along the border areas. Loess thickness of 50 feet is not uncommon on the borders of the lowan drift.…”

Bayesian chemical reaction neural network for autonomous kinetic uncertainty quantification

“…6 Consequently, prior expert knowledge is limited and first-principle simulation is computationally intractable, making the construction of chemical reaction models challenging. On the other hand, the development of diagnostics facilitates the generation of various measurements, 7 which lays the foundation for using data-driven approaches as a new paradigm for kinetic model construction. 8–10…”
