This is the first of a series of newly prepared guidelines on alternatives to allogeneic blood transfusion. Further guidelines including the use of cell salvage and of pharmacological approaches to blood conservation will be published in due course. Decades of clinical application demonstrate that it is quite feasible to auto-transfuse blood that has been collected and stored for an interval of...

As storage systems become increasingly heterogeneous and complex, it adds burdens on DBAs, causing suboptimal performance even after a lot of human efforts have been made. In addition, existing monitoring-based storage management by access pattern detections has difficulties to handle workloads that are highly dynamic and concurrent. To achieve high performance by best utilizing heterogeneous s...

OBJECTIVES Retaining residual newborn screening (NBS) bloodspots for medical research remains contentious. To inform this debate, we sought to understand public preferences for, and reasons for preferring, alternative policy options. METHODS We assessed preferences among 4 policy options for research use of residual bloodspots through a bilingual national Internet survey of a representative s...

In Delay Tolerant Networks (DTN) disruptions may happen frequently as end to end path is not available all the time. Thus, delays can also be extended due to its environment nature like deep space, underwater, ocean sensor networks. In manage to achieve message delivery probability in such demanding networking situations , researchers have proposed the design of store-carry-and-forward routing ...

Natural gas pipeline systems give merchants the ability to trade natural gas across time and geographical markets. That is, these systems embed two types of assets that merchants manage as real options: storage and transport. The current literature has studied the merchant management of these assets in isolation. In contrast, we consider their joint merchant management, which we model as a Mark...

We analyze the software stack of popular mobile advertising libraries on Android and investigate how they protect the users of advertising-supported apps from malicious advertising. We find that, by and large, Android advertising libraries properly separate the privileges of the ads from the host app by confining ads to dedicated browser instances that correctly apply the same origin policy. We...

Since the passage of the National Labor Relations Act in 1935, collective bargaining has been the primary means by which U.S. workers can collectively negotiate terms and conditions of employment with their employer. Currently, more than 100,000 contracts are in effect, covering approximately 9 million workers and their employers in the private sector. (An additional 8 million workers are cover...

We propose a generic framework for storage support in a distributed environment. This comprises a set of storage abstractions and storage policies: data clusters, cluster containers, and container domains, supporting sharing, caching, and replication. These abstractions and these policies are structured as fragmented objects (FOs), such that each storage system designer can ooer the appropriate...

Content-centric networking (CCN) has emerged as a dominant paradigm for future Internet architecture design due to its efficient support for content dissemination, which currently dominates Internet use. This dissertation shows how economic and social welfare analysis can be used to inform the design of a CCN architecture that provides network stakeholders with incentives to deploy and use. Fir...

Most previous work on buffer cache management uses an access-based placement policy that places a data block into a buffer cache at the block’s access time. This paper presents an eviction-based placement policy for a storage cache that usually sits in the lower level of a multi-level buffer cache hierarchy and thereby has different access patterns from upper levels. The main idea of the evicti...
