Objectives: To update the 2012 ESGAR consensus guidelines on the acquisition, interpretation and reporting of magnetic resonance imaging (MRI) for clinical staging and restaging of rectal cancer. Methods: Fourteen abdominal imaging experts from the European Society of Gastrointestinal and Abdominal Radiology (ESGAR) participated in a consensus meeting, organised according to an adaptation of the RAND-UCLA Appropriateness Method. Two independent (non-voting) Chairs facilitated the meeting.

The International Standards for Tuberculosis Care define the essential level of care for managing patients who have or are presumed to have tuberculosis, or are at increased risk of developing the disease. The resources and capacity in the European Union (EU) and the European Economic Area permit higher standards of care to secure quality and timely TB diagnosis, prevention and treatment. On this basis, the European Union Standards for Tuberculosis Care (ESTC) were published in 2012 as standards specifically tailored to the EU setting.

In this paper it is shown how to obtain a low-cost, high-resolution and fault-robust position sensing system for permanent magnet synchronous motor drives operating in safety-critical systems, by combining high-frequency signal injection with binary Hall-effect sensors. It is shown that the position error signal obtained via high-frequency signal injection can be merged easily into the quantization-harmonic-decoupling vector tracking observer used to process the Hall-effect sensor signals.

In this work we focus on Power Analysis Attacks (PAAs) which exploit the dependence of the static current of sub- 50nm CMOS integrated circuits on the internally processed data. Spice level simulations of static current as a function of the input state have been carried out to show that static power consumption of nanometer logic gates continues to exhibit a strong dependence on input vector even for sub-50nm circuits and that the coefficient of variation for a nand gate is strongly increasing with the scaling of CMOS technology.

Cloud Computing is the new technology that is changing our practices and attitudes. How should archivists arrange and describe resources in such environment? More specifically, how is the cloud environment going to affect arrangement and description theory and practice? What is the impact of preserving and providing access to archives in the cloudm in light of the traditional principles of provenance, respect des fonds and original order?What is the role of traditional finding aids , if any, in describing cloud-based fesources?

A new miniaturized figure-of-eight coil (μCoil) for TMS applications has been developed taking advantage of the Flex circuit technology. First experiments on volunteers demonstrated the ability of the μCoil to elicit sensorial action potentials of the peripheral nervous system. The necessity of reducing the size of standard TMS stimulator arises from the poor spatial resolution of the latter. This study aims to model the μCoil and study the electromagnetic fields induced inside the arm during peripheral nerve stimulation.
