In order to achieve optimal diagnostic performance in breast tomosynthesis (BT) imaging, the parameters of the imaging chain should be evaluated. For the purpose of such evaluations, a simulation procedure based on the Monte Carlo code system Penelope and the geometry of a Siemens BT system has been developed to generate BT projection images. In this work, the simulation procedure is validated by

Correlations between two high-pT hadrons provide information on how partons lose energy as they travel through the dense plasma formed at RHIC. To vary the path length partons travel, we measure the back-to-back jets in the AA collision of centrality and reaction-plane dependence, in addition to '2+1' particle correlations, and compare with p+p results.

We propose an online algorithm for energy minimization of transmitting stations in IEEE 802.11 wireless local area networks (WLANs). Our algorithm configures radio frequency (RF) parameters such as the number of transmitting antennas based on the real-time traffic demand and channel measurements so that the power consumption of the device is reduced and the minimum data rate requirements of statio

The EMPOST-NET project studied a new phenomenon: networking across different public and private sectors of society towards the most important goal of today – sustainable development. Sustainability networks are of special importance within the field of tourism, which is among the largest industries of today’s world, yet its environmental and socio-cultural impacts are often given too little attent

Gastroparesis is a well-known complication of diabetes mellitus, both in symptomatic and asymptomatic patients. Esophageal dysmotility has also been described, but is not as well-characterized. The etiology and effect of these complications need to be clarified. The aim of the present study was to evaluate esophageal and gastric motility, complications, gastrointestinal symptoms, and plasma biomar

The Research Institute for Fragrance Materials, Inc. (RIFM) has been engaged in the generation and evaluation of safety data for fragrance materials since its inception over 45 years ago. Over time, RIFM's approach to gathering data, estimating exposure and assessing safety has evolved as the tools for risk assessment evolved. This publication is designed to update the RIFM safety assessment proce
