Global Signatures and Dynamical Origins of the Little Ice Age and Medieval Climate Anomaly
Patterns of Change The global climate record of the past 1500 years shows two long intervals of anomalous temperatures before the obvious anthropogenic warming of the 20th century: the warm MedievalExpand

Atlantic hurricanes and climate over the past 1,500 years
Atlantic tropical cyclone activity, as measured by annual storm counts, reached anomalous levels over the past decade. The short nature of the historical record and potential issues with itsExpand

EM algorithms for Gaussian mixtures with split-and-merge operation
TLDR
In order to alleviate the problem of local convergence of the usual EM algorithm, a split-and-merge operation is introduced into the EM algorithm for Gaussian mixtures. Expand

Improving CUR matrix decomposition and the Nyström approximation via adaptive sampling
TLDR
We establish a general error bound for the adaptive column/row sampling algorithm, based on which we propose more accurate CUR and Nystrom algorithms with expected relative-error bounds. Expand

NPInter: the noncoding RNAs and protein related biomacromolecules interaction database
TLDR
NPInter is a database that documents experimentally determined functional interactions between noncoding RNAs (ncRNAs) and protein related biomacromolecules (PRMs) (proteins, mRNAs or genomic DNAs). Expand

Shrub encroachment with increasing anthropogenic disturbance in the semiarid Inner Mongolian grasslands of China
Abstract Many arid grasslands around the world are affected by shrub encroachment. However, the transition states of shrub-encroached ecosystems are still poorly known, and the effects of humanExpand

Bootstrapping SVM active learning by incorporating unlabelled images for image retrieval
TLDR
A new bootstrapping strategy for SVM active learning is proposed, in which the initial SVM classifier is trained with few labelled images and the unlabelled images randomly selected from the image database. Expand
