The demand to increase energy density of rechargeable batteries for portable electronic devices and electric vehicles reduce the cost grid-scale storage necessitates exploration new chemistries electrode materials batteries. open framework-structure Prussian-blue has recently been demonstrated as a promising cathode host variety monovalent multivalent cations with tunable working voltage discha...

toxoplasma encepfiautis (te) is rare in pediatric patients, but it is an emerging opportunistic infection in the increasing number of immunocompromised hosts. it should be considered in patients who present with fever and evolving cns symptoms. the outcome of these patients is always poor because of delay in diagnosis. we report one case of toxoplasma encephalitis in a child without hiv infecti...

This paper describes a simple protocol, the Remotely Keyed Encryption Protocol (RKEP), that enables a secure, but bandwidth-limited, cryptographic smartcard to function as a high-bandwidth secret-key encryption and decryption engine for an insecure, but fast, host processor. The host processor assumes most of the computational and bandwidth burden of each cryptographic operation without ever le...

While irradiation of red cell concentrates (RCC) prevents graft-versus-host disease in susceptible transfusion recipients, it also damages red blood cells (RBC). To understand the ability of irradiation regulations to prevent transfusion of inferior units, we irradiated 980 RCC in saline-adenine-glucose-mannitol (SAGM) using various combinations of pre-irradiation age and post-irradiation stora...

We investigate the potential for hydrogen storage of a new class of nanomaterials, metal-diboride nanotubes. These materials have the merits of a high density of binding sites on the tubular surfaces without the adverse effects of metal clustering. Using the TiB2 (8,0) and (5,5) nanotubes as prototype examples, we show through first-principles calculations that each Ti atom can host two intact ...

Urea, like many network forming compounds, has long been known to form inclusion (guest-host) compounds. Unlike other network formers like water, urea is not known to form such inclusion compounds with simple molecules like hydrogen. Such compounds if they existed would be of interest both for the fundamental insight they provide into molecular bonding and as potential gas storage systems. Urea...

Host-side flash-based caching offers a promising new direction for optimizing access to networked storage. Current work has argued for using host-side flash primarily as a read cache and employing a write-through policy which provides the strictest consistency and durability guarantees. However, write-through requires synchronous updates over the network for every write. For write-mostly or wri...

File systems hosting virtual machines typically contain many duplicated blocks of data resulting in wasted storage space and increased storage array cache footprint. Deduplication addresses these problems by storing a single instance of each unique data block and sharing it between all original sources of that data. While deduplication is well understood for file systems with a centralized comp...
