Mt. Cameroon is one of the most active volcanoes in Africa and poses a possible threat to about half a million people in the area, yet knowledge of the volcano's underlying magma supply system is sparse. To characterize Mt. Cameroon's magma plumbing system, we employed mineral-melt equilibrium thermobarometry on the products of the volcano's two most recent eruptions of 1999 and 2000. Our resul...

Graphene has recently emerged as a novel material in the biomedical field owing to its optical properties, biocompatibility, large specific surface area and low cost. In this paper, we provide the first demonstration of the possibility of using light to remotely trigger the release of drugs from graphene in a highly controlled manner. Different drugs including chemotherapeutics and proteins are...

episodic memory store of personally experienced events from the past, including details not only of the content of the episode but also of its context — when and where it occurred. semantic memory our general knowledge about the world, such as information about words and their meanings, facts, concepts, objects and people; typically retrieved without recollection of where and when the informati...

Many countries face serious strategic challenges with the future supply of both aggregates and critical elements. Yet, at same time, they must sustainably manage continued multimillion tonne annual arisings mineral-dominated wastes from mining industry. In an antithesis circular economy principles, these continue to be landfilled despite often comprising valuable components, such as metals, soi...

Working memory (WM) refers to the temporary storage and processing of goal-relevant information. WM is thought to include domain-specific short-term memory stores and executive processes, such as coordination, that operate on the contents of WM. To examine the neural substrates of coordination, we acquired functional magnetic resonance imaging data while subjects performed a WM span test design...

Tertiary storage systems are used when secondary storage can not satisfy the data storage requirements and/or it is a more cost effective option. The new application domains require on-demand retrieval of data from these devices. This paper investigates issues in optimizing I/O time for a query whose data resides on automated tertiary storage containing multiple storage devices.

Norway is a country with large geographical dimensions and a very low number of inhabitants. This combination makes advanced telecommunication services and distributed multimedia applications, like telemedicine and distance education, very important for the Norwegian society. Obviously, an appropriate networking infrastructure is necessary to enable such services and applications. In order to c...

Heterogeneous disk arrays are becoming a common configuration in many sites and specially in storage area networks (SAN). As new disks have different characteristics than old ones, adding new disks or replacing old ones ends up in a heterogeneous disk array. Current solutions to this kind of arrays do not take advantage of the improved characteristics of the new disks. In this paper, we present...

It is always the hotspot of society attention and academy study how to improve the efficiency of large-scale instruments and equipment (LSIE). Constructing a Data Collection System based on Wireless Local Area Network (WLAN) is an important method of lab performance management and then promoting the LSIE integration efficiency. Focus on the WLAN environment LSIE working state information collec...
