Improving grid-connected tidal power systems through PWM inverters based on voltage-oriented control
International Journal of Electrical Engineering and Applied SciencesPulse width modulation (PWM) rectifiers play a critical role in AC to DC power conversion for renewable energy applications. Existing systems predominantly employ basic voltage-oriented control (VOC) strategies and conventional 2-level converters, which

Cryptotephra from a ~120 ka Tondano eruption in a sediment core from Lake Towuti (Indonesia)
Journal of Quaternary Science, EarlyView.ABSTRACT Southeast Asia is one of the most volcanically active regions in the world, yet their long‐term eruptive history has been comparatively little studied. In particular, little work has explored the potential of sedimentary archives to record distal cryptotephra, which may help in identifying some of the region's larger Quaternary eruptions. Here,

Raman Analysis of Roman Mosaics From the Upper Guadalquivir Valley (Spain)
Journal of Raman Spectroscopy, EarlyView.This work is focused on the Raman analysis of two Roman mosaics from Jaén (Spain) using portable and benchtop equipment, complemented by elemental analysis using EDXRF and petrographic analysis. The results obtained have provided a detailed characterisation of the tesserae.

Nutrient‐dependent thermal response in growth and stoichiometry of Antarctic phytoplankton
Limnology and Oceanography, EarlyView.Abstract Rising temperatures and altered nutrient supply are expected to influence future phytoplankton thermal performance and community dynamics. The thermal response of phytoplankton has been shown to be influenced by nutrient availability, but information is still limited, particularly for the coastal Southern Ocean.
