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).

Venus Ground-Based Observations: a Proposal
We have executed an efficient procedure for time-sharing to achieve a rapid Venus observation on Keck I/HIRES.

Development of a Transillumination Infrared Modality for Differential Vasoactive Optical Imaging
We present the development and implementation of a new near infrared transillumination imaging modality for tissue imaging. Exogenous inhaled hyperoxic and hypercarbic gases are used as “vasoactive contrast agents” via the production of changes in concentration of the endogenous HbO(2) and Hb in blood.

Target Tracking with Incomplete Detection
In this paper, we address the multiple target tracking problem as a maximum a posteriori problem.

Data-Driven Lexicon Expansion for Mandarin Broadcast News and Conversation Speech Recognition
We present a data-driven framework for expanding the lexicon to improve Mandarin broadcast news and conversation speech recognition.

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.

Isolines: efficient spatio-temporal data aggregation in sensor networks
This paper introduces an energy-efficient data collection technique that takes advantage of spatial and temporal data correlation for monitoring continuously changing conditions such as temperature, humidity, rain fall, radiation, substance concentrations, etc.

Embracing interference in ad hoc networks using joint routing and scheduling with multiple packet reception
We present an approach that takes advantage of multi-packet reception (MPR) to reduce the negative effects of multiple access interference and therefore increase the capacity of an ad hoc network.

Powers of 10: modeling complex information-seeking systems at multiple scales
New models of information-seeking support systems offer two advantages: they move us from prescientific conceptual frameworks about information seeking to more rigorous scientific theories and predictive models while, at the same time, expanding the kinds of things we study and develop.

Predicate privacy in encryption systems
In this paper, we consider a new notion called predicate privacy, that is, the property that a token should not reveal information about the query predicate encoded in it.
