U-Li Isotopes highlight the dominant role of glacier coverage in weathering processes across Northeast Tibetan Plateau glacial watersheds
No full textThis study investigates uranium (U) and lithium (Li) isotope fractionation in suspended particulate matter (SPM) from glacial basins in the northeastern Tibetan Plateau, aiming to explore the coupling between physical and chemical weathering processes under glacial influence. The (234U/238U) activity ratio is correlated with parameters related to glacial activity, such as the elevation of the basin and glacier area. Samples from glacial watersheds are enriched in 234U (mean 1.28 ± 0.11), indicating the efficient comminution of rocks. Conversely, non-glacial areas show lower (234U/238U) ratios due to weakened physical weathering (mean 1.09 ± 0.04). The Li isotopes are sensitive to chemical weathering, providing complimentary information to U isotopes. In glacial watersheds, the variation of δ7LiSP is minimal and compatible with the signature of unaltered bedrock (mean 1.58 ± 0.87 ‰). Samples from lower basins show a stronger fractionation (mean − 2.61 ± 1.26 ‰), pointing to a stronger chemical weathering. As for U, Li fractionation is also related to topographic variables influencing the degree of glacial activity. Where glaciers are active, physical weathering fractionates U isotopes but no Li isotopes. Where glaciers are not present, physical weathering is less important, while chemical alteration is more relevant, leading to a low fractionation of U isotopes and a strong fractionation of Li isotopes. The combined use of U and Li isotopes offers an effective tool for tracing weathering regimes shaped by geomorphic and climatic factors, highlighting the role of glaciers in silicate weathering and landscape evolution, and demonstrating the proxies' potential for reconstructing recent glacial weathering

Multi-objective imperfect maintenance for dependent competing risk systems with multiple degradation processes
No full textMultiple competing risks are one of the important topics in reliability field, especially degradation processes and random shocks. This research aims to relax the independent assumption by considering that there exist dependent relationships not only among multiple degradation measures but also between degradation measure and random shocks. In reality, many systems have multiple components with more than one degradation measure which is dependent with each other due to their interplaying functions or common usage history. Independent assumption may underestimate system reliability estimation under many cases. Random shocks will also contribute to the system failure through two ways: (1) one is working directly on the degradation processes; (2) the other is causing immediate failure to the system. We develop a new methodology to formulate the reliability prediction model for the gradually degradating systems subject to multiple dependent competing risks of degradation processes and random shocks. Two kinds of random shocks are considered: (1) fatal shocks, which fail the system immediately; (2) non-fatal shocks, which exhibit two effects on the system degradation process, including sudden degradation increment and degradation rate acceleration. The dependency between degradation processes and random shocks are modulated by a time-scaled covariate factors while the dependency among degradation processes are fitted by copula method. Also the reliability and state probability estimation for the systems are derived under the research scope of multi-state system using both analytical and Monte Carlo simulation for the dependent competing-risk systems. Different maintenance policy models involving imperefect preventive maintenance for this dependent model are introducted and compared with each other. Multi-objective optimization is applied to consider two important targets simultaneously in maintenance issues, including long-run expected cost rate and system availability.Ph.

Interstitial anionic electrons favoring superconductivity in Li-As electrides
No full textInterstitial anionic electrons (IAEs) at lattice cavities of electrides, which have diverse morphologies and concentrations, can induce interesting physical and chemical properties. Understanding the correlation between IAEs and electron-phonon coupling is crucial for the development of new electride superconductors. We have applied first-principles structural search calculations to predict new high-pressure Li-As electrides, such as P6/mmm LixAs (x=5 and 8), Li6As with Cmc21 and C2/c symmetries, and C2/mLi10X (X=As and Sb), which together with the already known C2/mLi10Te compound present favorable characteristics (i.e., variable donor content, structural symmetries, and acceptor species) to explore IAE-related superconductivity. According to our results, the predicted superconducting temperatures of these electrides are positively correlated with the number and connectivity of IAEs.This work was supported by the Natural Science Foundation of China (Grants No. 52025026, No. 21873017, No. 21573037, No. 22372142, and No. 12304028), the Postdoctoral Science Foundation of China (Grant No. 2013M541283), the Innovation Capability Improvement Project of Hebei Province (Grant No. 22567605H), the Natural Science Foundation of Hebei Province (Grant No. B2021203030), and the Science and Technology Project of the Hebei Education Department (Grants No. JZX2023020 and No. QN2023246).
