Simultaneous Quantification of Perfusion and Permeability in the Prostate Using Dynamic Contrast-Enhanced Magnetic Resonance Imaging with an Inversion-Prepared Dual-Contrast Sequence
The aim of the present study was to quantify both perfusion and extravasation in the prostate to discriminate tumor from healthy tissue, which might be achieved by dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) using a nonspecific low-molecular-weight contrast medium (CM).

Using Evidence Centered Design For Learning (ECDL) To Examine the ASSISTments system
We introduce a design methodology – Evidence Centered Design for Learning (ECDL) that supports the design of educational systems in terms of evidentiary arguments.

Using Mixed-Effects Modeling To Analyze Different Grain-Sized Skill Models In An Intelligent Tutoring System
Student modeling and cognitive diagnostic assessment are important issues that need to be addressed for the development and successful application of intelligent tutoring systems (ITS). ITS needs the construction of complex models to represent the skills that students are using and their knowledge states, and practitioners want cognitively diagnostic information at a finer grained level.…

InP-Based Geiger-Mode Avalanche Photodiode Arrays for Three-Dimensional Imaging at 1.06 μm
We report on the development of 32 x 32 focal plane arrays (FPAs) based on InGaAsP/InP Geiger-mode avalanche photodiodes (GmAPDs) designed for use in three-dimensional (3-D) laser radar imaging systems at 1064 nm.

Exploiting User Feedback for Language Model Adaptation in Meeting Recognition
We investigate language model (LM) adaptation in a meeting recognition application, where the LM is adapted based on recognition output from relevant prior meetings and partial manual corrections.

The Temporal Evolution of O(1D) Emission in Ionospheric Modification Experiments
Understanding processes involving atomic oxygen is crucial for the study of energy transfer and transport dynamics in the upper atmosphere.

A Safety-Case Approach for Certifying Adaptive Systems
In this paper, we argue that analysis tools based on recent advances in formal methods (SMT solvers, infinite bounded model checkers, and k-induction) can provide suitable modeling notations, effective analysis, and push button automation.
