Kalzium Ist Nicht Alles

Elevation of cerebral Mg2+ with a novel orally delivered ionophore, magnesium threonate, enhances cognition in young and old rats over a 12-24 day treatment interval, as outlined in a paper by Slutsky et al. in this issue of Neuron. Despite both Mg2+ and Zn2+ blocking the NMDA receptor channel, sustained extracellular Mg2+ elevation mimics sustained synaptic Zn2+ concentrations by increasing hi...

Sampling Random Transfer Functions ' WeM 13 - 3

Recently, considerable attention has been paid to the use of probabilistic algorithms for analysis and design of robust control systems. However, since these algorithms require the generation of random samples of the uncertain parameters, their application has been mostly limited to the case of parametric uncertainty. Notable exceptions to this limitation are the algorithm for generating FIR tr...

The Meinunger “Nicht Rote” Objects

Four high-latitude slow variable stars have been noted by Meinunger (1972) as “nicht rote” (“not red”) objects and thus curious. We have previously reported (Margon & Deutsch 1997) that one of these objects, CC Boo, is in fact a QSO. Here we present observations demonstrating that the remaining three are also highly variable active galactic nuclei. The most interesting object of the four is per...

Intelligente Lokalisierung von Gegenständen mit Complex Event Processing

Das Auffinden einzelner Gegenstände stellt in großen Warenbeständen aufgrund der Menge und nicht eindeutiger Lagerstandorte ein Problem dar. Dies ist besonders dann der Fall, wenn Kunden die Position der Gegenstände verändern, so dass eine zuverlässige Aussage eines konventionellen Informationssystems nicht möglich ist. Dieser Artikel beschreibt anhand der Lokalisierung von Büchern in einer Bib...
