Amide proton transfer (APT) imaging has shown promise as an indicator of tissue pH and as a marker for brain tumors. Sources of error in APT measurements include direct water saturation, and magnetization transfer (MT) from membranes and macromolecules. These are typically suppressed by postprocessing asymmetry analysis. However, this approach is strongly dependent on B(0) homogeneity and can i...

On the basis of the results of the AKARI far-infrared deep surveys, we propose a multi-wavelength far-infrared deep cosmological survey with SAFARI on SPICA. We have carried out a far-infrared deep cosmological survey with AKARI, and successfully obtained the galaxy counts and new limits on the absolute brightness of the cosmic far-infrared background. These results provide strong constraints o...

Lydia is a framework for Model-Based Diagnosis (MBD). We have used the Safari diagnostic reasoner (part of Lydia) to solve the synthetic track problems in the DXC’09 diagnostic challenge. In this paper we describe our approach.

An approach is presented to estimate the surface aerosol radiative forcing by use of collocated cloud-screened narrowband spectral and thermal-offset-corrected radiometric observations during the Puerto Rico Dust Experiment 2000, South African Fire Atmosphere Research Initiative (SAFARI) 2000, and Aerosol Characterization Experiment-Asia 2001. We show that aerosol optical depths from the Multip...

ZooKeeper [1] is a commonly used service for coordinating distributed applications. ZooKeeper uses leader-based atomic broadcast for writes, so that all state modifications are globally totally ordered, but it allows stale reads from any server for high read availability. This design trades high read throughput for potentially high write latency. Unfortunately, the extent of this tradeoff and t...

Intranets hold great promise as `̀ organizational Internets'' to allow information sharing and collaboration across departments, functions and different information systems within an organization. Yet not much is known about how to implement intranets. We adapt a taxonomy based on institutional theory and distinguish six broad diffusion drivers that might be considered to sustain the implementat...
