Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Background The acidic weathering of soils is known as a problem for decades. It leads to the deterioration of essential soil properties, including soil fertility, water, or cation buffering capacity due to solution and solid storage of Al3+ by polymerization in the interlayer of (former) swellable clay minerals.

A Middle and Late Devensian sequence from the northern part of Kents Cavern (Devon, UK)
Journal of Quaternary Science, EarlyView.Abstract 1920s/30s excavation of a Middle Devensian sequence in the northern part of Kents Cavern recovered important Late Middle and Early Upper Palaeolithic archaeological material, including Britain's oldest known Homo sapiens remains. Questions remain about this material, including how it came to be in the cave.

Disparate home range dynamics reflect nutritional inadequacies on summer range for a large herbivore
EcosphereThe spatial distribution of animals has consequences for nutrition, predator–prey dynamics, spread of diseases, and population dynamics in general. Animals must establish a home range to secure adequate resources to fuel their energy needs.

Journal of Quaternary Science, EarlyView.ABSTRACT Northwest Europe experienced high‐amplitude climate change at the onset and end of the Younger Dryas (YD; ca 12 800–11 600 cal a BP), a crucial period to develop our understanding of natural climate dynamics. European palaeoclimatological records generally suggest a bipartite structure of the YD, potentially due to a northward retreat of the ...

ALPINE: A Bayesian System for Cloud Performance Diagnosis and Prediction [PDF]
arXiv, 2016 Cloud performance diagnosis and prediction is a challenging problem due to the stochastic nature of the cloud systems. Cloud performance is affected by a large set of factors including (but not limited to) virtual machine types, regions, workloads, wide area network delay and bandwidth.

ALPINE: Active Link Prediction using Network Embedding [PDF]
arXiv, 2020 Many real-world problems can be formalized as predicting links in a partially observed network. Examples include Facebook friendship suggestions, consumer-product recommendations, and the identification of hidden interactions between actors in a crime network. Several link prediction algorithms, notably those recently introduced using network embedding,

Journal of Quaternary Science, EarlyView.Abstract The high mountains of Taiwan provide a unique location for Quaternary palaeoclimate research in East Asia and the north‐western Pacific. This study applies geomorphological field mapping and rock surface exposure dating with paired (10Be/26Al) in situ‐produced terrestrial cosmogenic nuclides to identify and date glacial landforms and boulders ...
