Artificial intelligence (AI) uses mathematical algorithms to perform tasks that require human cognitive abilities. AI-based methodologies, e.g., machine learning and deep learning, as well as the recently developed research field of radiomics have noticeable potential to transform medical diagnostics. AI-based techniques applied to medical imaging allow to detect biological abnormalities, to...

It has been more than 20 years since Deutsch and Hayden proved the locality of quantum theory, using the Heisenberg picture of quantum computational networks. Of course, locality holds even in the face of entanglement and Bell’s theorem. Today, most researchers in quantum foundations are still convinced not only that a local description of quantum systems has not yet been provided, but that...

Industrial robots are commonly used to perform interaction tasks (such as assemblies or polishing), requiring the robot to be in contact with the surrounding environment. Such environments are (partially) unknown to the robot controller. Therefore, there is the need to implement interaction controllers capable of suitably reacting to the established contacts. Although standard force controllers...

Tests for dependence of continuous, discrete and mixed continuous-discrete variables are ubiquitous in science. The goal of this paper is to derive Bayesian alternatives to frequentist null hypothesis significance tests for dependence. In particular, we will present three Bayesian tests for dependence of binary, continuous and mixed variables. These tests are nonparametric and based on the...

Because of evidence of causal association between antibiotic use and bacterial resistance, the implementation of national policies has emerged as a interesting tool for controlling and reversing bacterial resistance. The aim of this study is to assess the impact of public policies on antibiotic use in Europe using a differences-in-differences approach. Comparable data on systemic...

This paper considers a specific communicative activity type of the financial context – analysts and investors conference calls – from an argumentative perspective. On the basis of a concrete example bound to an important and very recent merger story (the failed attempt to combine Barclays and ABN AMRO banks), it is shown that conference calls, apparently conceived for ...

Middleware for Web service compositions, such as BPEL engines, provides the execution environment for services as well as additional functionalities, such as monitoring and self-tuning. Given its role in service provisioning, it is very important to assess the performance of middleware in the context of a Service-oriented Architecture (SOA). This paper presents SOABench, a framework for the...

We present the results and the lessons learned from two separate and independent studies into the design, development, and evaluation of electronic books for information access: the Visual Book and the Hyper-TextBook. The Visual Book explored the importance of the visual component of the book metaphor in the production of “good” electronic books for referencing. The Hyper-TextBook...

Many workload characterization studies depend on accurate measurements of the cost of executing a piece of code. Often these measurements are conducted using infrastructures to access hardware performance counters. Most modern processors provide such counters to count micro-architectural events such as retired instructions or clock cycles. These counters can be diffocult to configure, may not be...

As part of a Distributed Information Retrieval system a description of each remote information resource, archive or repository is usually stored centrally in order to facilitate resource selection. The acquisition of precise resource descriptions is therefore an important phase in Distributed Information Retrieval, as the quality of such representations will impact on selection accuracy, and...
