DOI: 10.1002/ece3.6758
Abstract: Abstract The “green wave” hypothesis posits that during spring consumers track spatial gradients in emergent vegetation and associated foraging opportunities. This idea has largely been invoked to explain animal migration patterns, yet the general phenomenon… read more here.

DOI: 10.1007/jhep02(2022)182
Abstract: We extend in two directions our recent investigation of strongly interacting quantum fields in a class of spacetimes with chronology horizons (Misner spacetimes). First, we generalize to arbitrary dimensions the holographic mechanism of chronology protection… read more here.

DOI: 10.1007/s00445-019-1325-6
Abstract: Constraining the age of young lavas, which generally fall outside the effective range of traditional geochronology methods, remains a key challenge in volcanology, limiting the development of high-resolution eruption chronologies. We present an in situ… read more here.

DOI: 10.1016/j.dendro.2017.10.002
Abstract: Abstract This paper describes a tree-ring width chronology that spans the past 4650 years, established using the recently developed eigenanalysis technique. The aim is to show whether this eigenanalysis method enables the extraction of long-term… read more here.

DOI: 10.1016/j.dendro.2020.125722
Abstract: Abstract In spite of enormous diversity in tree species, dendrochronological records in the tropical Andes are very scarce. Therefore, it is necessary to increase the search for new tree species with high dendrochronological characteristics in… read more here.

DOI: 10.1016/j.icarus.2019.113514
Abstract: Subsequent to the Moon's formation, late accretion to the terrestrial planets modified their silicate crusts and mantles. We combine dynamical N-body and Monte Carlo simulations to determine impact probabilities, impact velocities, and expected mass augmentation… read more here.

DOI: 10.1016/j.jseaes.2020.104490
Abstract: Abstract The Cenozoic history of aridification in the Asian interior is thought to be intimately linked to uplift of the Tibetan Plateau and long-term global cooling. How fluctuating climatic conditions influenced regional moisture levels during… read more here.
