Two types of modern sediment dispersal systems in the western Taiwan foreland basin: Sediment transfer from basin to basin

open access: yesThe Depositional Record, EarlyView.
A classical peripheral foreland basin is bounded longitudinally by a pair of marginal ocean basins (DeCelles & Giles, 1996). The WTFB sediments transfer to adjacent marginal ocean basins. The western Taiwan foreland basin (WTFB) is regarded as a classical peripheral foreland basin, longitudinally bounded by the southern Okinawa Trough (SOT) to the ...

Human phase‐I metabolism of three synthetic cannabinoids bearing a cumyl moiety and a cyclobutyl methyl or norbornyl methyl tail: Cumyl‐CBMEGACLONE, Cumyl‐NBMEGACLONE, and Cumyl‐NBMINACA

open access: yesDrug Testing and Analysis, EarlyView.
The human phase‐I metabolism of three SCRAs bearing a cumyl moiety and a CBM or NBM tail, based on LC‐qToF‐MS data of authentic urine specimens. Abstract Synthetic cannabinoid receptor agonists (SCRAs) continue to show high prevalence on the new psychoactive substances drug market.

Improving the Determination of Carbon Isotope Ratios of Endogenous Steroids Found in Human Serum

open access: yesDrug Testing and Analysis, EarlyView.
A method employing high‐performance liquid chromatographic sample cleanup to determine the carbon isotope ratios of steroids found in human serum was developed and fully validated. A reference population encompassing more than 120 male and female athlete samples was investigated in order to establish population‐based thresholds for Δ‐values.

Coherent changes in wood charcoals, site occupation and lithic technology across the MIS 4/3 transition at Klein Kliphuis rock shelter, South Africa

open access: yesJournal of Quaternary Science, Volume 38, Issue 1, Page 38-48, January 2023., 2023
Abstract We explore the correspondence between changing palaeoenvironments, patterns of site use, and lithic technology at the rock shelter site Klein Kliphuis (South Africa) across the interval 65–55 000 years before present. This period coincides with the termination of Marine Isotope Stage (MIS) 4, and the disappearance of an iconic late Pleistocene
