The thin and medium filters of the EPIC camera on-board XMM-Newton: measured performance after more than 15 years of operation

2016

After more than 15 years of operation of the EPIC camera on board the XMM-Newton X-ray observatory, we have reviewed the status of its Thin and Medium filters. We have selected a set of Thin and Medium back-up filters among those still available in the EPIC consortium and have started a program to investigate their status by different laboratory measurements including: UV/VIS transmission, Raman scattering, X-Ray Photoelectron Spectroscopy, and Atomic Force Microscopy. Furthermore, we have investigated the status of the EPIC flight filters by performing an analysis of the optical loading in the PN offset maps to gauge variations in the optical and UV transmission. We both investigated repea…

South Pole glacial climate reconstruction from multi-borehole laser particulate stratigraphy

2013

AbstractThe IceCube Neutrino Observatory and its prototype, AMANDA, were built in South Pole ice, using powerful hot-water drills to cleanly bore>100 holes to depths up to 2500 m. The construction of these particle physics detectors provided a unique opportunity to examine the deep ice sheet using a variety of novel techniques. We made high-resolution particulate profiles with a laser dust logger in eight of the boreholes during detector commissioning between 2004 and 2010. The South Pole laser logs are among the most clearly resolved measurements of Antarctic dust strata during the last glacial period and can be used to reconstruct paleoclimate records in exceptional detail. Here we use…

A special issue, “Remembering the Past and the Future - Korean Culture in a Changing World,” is devoted to understanding Korean culture. Regardless of the bulk of comprehensive information available today, accurate knowledge of the Asian culture in Europe or the European culture in Asia has not become considerably deeper. Sometimes even to the contrary – the old stereotypes continue to exist as part of the packaging for pseudo information adjusted to the short-term goals of the contemporary globalised society, supplemented by travel guides and announcements tailored to the needs of immediate politically economic conjuncture. And yet, this is only the top of the intercultural communication i…

The State of the Unions

2021

What defines an economic region and distinguishes it from other spatial concepts? This fundamental question is addressed based on the dimensions of space, borders, action and time. An overview of the landscape of African Regional Economic Communities (RECs) follows. RECs are briefly portrayed, and the bewildering multitude of RECs is demystified to create a better understanding of the pattern of economic integration in Africa. The exercise is guided by a matrix of general-purpose versus functional/sectoral as well as effectual versus ineffectual/dormant economic unions. This analysis forms the basis for a critical discussion of the African Union’s practice of only granting official recognit…

New epicardial mapping electrode with warming/cooling function for experimental electrophysiology studies

2010

Cardiac electrical activity is influenced by temperature. In experimental models, the induction of hypothermia and/or hyperthermia has been used for the study of mechanisms of cardiac arrhythmia. A system that allows for localized, controlled induction, besides simultaneously recording electrical activity in the same induced area, needs to be developed ad hoc. This article describes the construction and application of a new system capable of locally modifying the epicardial temperature of isolated hearts and of carrying out cardiac mapping with sufficient spatial resolution. The system is based on a thermoelectric refrigerator and an array of 128 stainless steel unipolar electrodes in encap…

Pacemaker therapy in premature children with high degree AV block.

1998

The smallest pacemaker pulse generator and a steroid-eluting bipolar epicardial lead were implanted in two premature children with symptomatic AV block. Stable capture threshold and high amplitude evoked response electrogram resulted in normal function of the pacemaker Autocapture algorithm, which adjusts output 0.3 V above the measured capture threshold. Autocapture had previously been used only with endocardial leads. Longer-term observation is required.
