Chemical weathering as a tool for distinguishing river terraces of varying ages: a case study of the Qingyi River on the eastern Tibetan Plateau

open access: yesFrontiers in Earth Science
River terraces are essential objects for studying Quaternary landforms and active tectonics. Previous researchers often identified river terraces formed in different eras by height and landmark strata.

Organic carbon and total nitrogen stocks in soils of the Lena River Delta [PDF]

open access: yesBiogeosciences, 2013
The Lena River Delta, which is the largest delta in the Arctic, extends over an area of 32 000 km2 and likely holds more than half of the entire soil organic carbon (SOC) mass stored in the seven major deltas in the northern permafrost regions.

Developing a universal tunnel span classification from global tunnel databases

open access: yesDeep Underground Science and Engineering, EarlyView.
A universal tunnel span classification system is introduced that incorporates tunnel span, cross‐sectional area, typical tunnel types, and intended uses. Representative flatness ratio values are also provided for each span class. The classification is derived from a comprehensive database of 450 tunnel profiles from 47 countries.

Pleistocene terraces in the Hochrhein area : formation, age constraints and neotectonic implications [PDF]

open access: yes, 2008
Pleistocene fluvial gravel terraces appear to be useful to decipher neotectonic movements. To achieve this, however, chronologic and sedimentologic data on the terraces are required. Thus, this thesis represents a multidisciplinary approach.

Creation of a Landslide Susceptibility Map Using Short‐Term Data From the July 2018 Heavy Rainfall in Southern Hiroshima Prefecture

open access: yesGeological Journal, EarlyView.
This work advances landslide susceptibility mapping by incorporating short‐term trigger data with landscape susceptibility mapping. We also examine the importance of downsampling, watershed delineation and geospatial correlations in evaluating outcomes.

Spatially Resolved Metabolomics of Optimal Cutting Temperature (OCT) Compound‐Embedded Tumors

open access: yesInternational Journal of Cancer, EarlyView.
ABSTRACT Mass spectrometry imaging (MSI) is emerging as a powerful tool for uncovering the distribution of metabolites in the tumor microenvironment and studying tumor metabolism in vivo. To date, MSI of biobanked tissues contextualized by patient data has been limited to peptides, proteins, and glycans—with few examples for metabolites.
