Climate changes and trends in phenology and yields of field crops in China, 1981-2000
Abstract A warming trend has become pronounced since the 1980s in China and is projected to accelerate in the future. Concerns about the vulnerability of agricultural production to climate change areExpand

Optimal recovery of single disk failure in RDP code storage systems
Modern storage systems use thousands of inexpensive disks to meet the storage requirement of applications. To enhance the data availability, some form of redundancy is used. For example, conventionalExpand

Cooperative Recovery of Distributed Storage Systems from Multiple Losses with Network Coding
This paper studies the recovery from multiple node failures in distributed storage systems. We design a mutually cooperative recovery (MCR) mechanism for multiple node failures. Via a cut-basedExpand

Climate change and critical thresholds in China’s food security
Identification of ‘critical thresholds’ of temperature increase is an essential task for inform policy decisions on establishing greenhouse gas (GHG) emission targets. We use the A2 (medium-high GHGExpand
