Current photon counting x-ray detector (PCD) technology faces limitations associated with spectral fidelity and photon starvation. One strategy for addressing these limitations is to supplement PCD data with high-resolution, low-noise data acquired with an energy-integrating detector (EID). In this work, we propose an iterative, hybrid reconstruction technique which combines the spectral proper...

Numerous services are being offered over the Internet and require identification of users as in face-to-face interactions. To simplify the authentication procedure and reduce the need to manage multiple credentials to access services, Electronic Identification (eID) schemes have been introduced. eID schemes commonly involve many service providers (SPs) which provide services, such as online sho...

Some researchers have argued that providing operators with externalized, graphic representations can lead to a trade-off whereby deep knowledge is sacrificed for cognitive economy and performance. This article provides an initial empirical investigation of this hypothesis by presenting a longitudinal study of the effect of ecological interface design (EID), a framework for designing interfaces ...

This work presents a prototype implementation of a smartphone as secure eID reader using NFC technology. The presented approach aims to reach a security level close to standalone smart card readers. This security level will be allowed by the means of a trusted execution environment (TEE) which allows strong isolation and separation for critical applications and provides trusted, not interceptab...

To the editor, In response to: Assessment of oxygenation after balloon pulmonary angioplasty for patients with inoperable chronic thromboembolic hypertension. We read interest study by Matsuoka et al. [1] reporting on effects (BPA) tissue oxygenation. Despite an improvement in haemodynamics following BPA, authors conclude that oxygenation, exercise-induced desaturation (EID) and exertional dys...
