Impact of Alignment Parameters on Train Dynamics and Structure Vibration in Curved Floating Slab Tracks

Engineering Reports, Volume 8, Issue 1, January 2026.
This study investigates the impact of alignment parameters on train dynamic responses and structural vibrations in floating slab tracks during curved train operations, utilizing a mathematical model to predict and evaluate driving safety and structural vibration behavior.

Early Cretaceous–Late Miocene Basin–Mountains Pattern in the Northeastern Margin of the Tibetan Plateau, NW China: Evidence From Detrital Zircon Chronology in the Lanzhou Basin

Geological Journal, Volume 61, Issue 1, Page 127-145, January 2026.
Using DZmix and DZstats models, we quantified the contributions of potential sources of the Lanzhou basin. Our findings indicate that the Cenozoic cooling and denudation signals primarily originated from Qilian and West Qinling, which were the main sediment sources.

Evaluating Simulated Groundwater Contributions to Streamflow in a Data‐Scarce, Semi‐Arid Catchment in South Africa

Hydrological Processes, Volume 40, Issue 1, January 2026.
Calibration procedure selection should be carefully considered in data‐scarce circumstances, as good model efficiency does not necessarily guarantee a realistic representation of hydrological processes. Stable isotopes proved effective in validating model results and detecting shortcomings in the J2000 model caused by sparse hydroclimatic data and the ...

The mineral and isotopic signatures of glacially eroded sediments exported from Hudson Strait to the Labrador Sea during Hudson Strait Heinrich events H0 to H4

Journal of Quaternary Science, Volume 41, Issue 1, Page 4-24, January 2026.
ABSTRACT The sediment signature of glacial erosion products exported from Hudson Strait to the Labrador Sea during Hudson Strait Heinrich (HS‐H) events is evaluated using four distinct proxies: paired δ18Ο and δ13C data on the carbonate fraction, εNd and U–Pb isotopes in the silicate fraction, the mineral composition of the <2 mm bulk sediment fraction,

Autonomous, high‐frequency and long‐term monitoring of substrate temperature in rocky intertidal zones

Limnology and Oceanography: Methods, Volume 24, Issue 1, January 2026.
Abstract Intertidal zones are characterized by complex and dynamic thermal mosaics, where organisms experience extreme temperature variations influenced by microclimatic factors. However, accurately monitoring rocky shore temperatures over the long term remains challenging due to the limitations of conventional temperature loggers.
