BeppoSAX observed several galactic binary X–ray pulsars during the Science Verification Phase and in the first year of the regular program. The complex emission spectra of these sources are an ideal target for the BeppoSAX instrumentation, that can measure the emission spectra in an unprecedented broad energy band. Using this capability of BeppoSAX a detailed observational work can be done on t...

Two emerging hardware trends have re-initiated the development of in-core database systems: ever increasing main-memory capacities and vast multi-core parallel processing power. Main-memory capacities of several TB allow to retain all transactional data of even the largest applications in-memory on one (or a few) servers. The vast computational power in combination with low data management over...

The increasing availability of low-cost air quality sensors has led to novel sensing approaches. Distributed networks sensors, together with data fusion and analytics, have enabled unprecedented, spatiotemporal resolution when observing the urban atmosphere. Several projects demonstrated potential different approaches for high-resolution measurement ranging from static, sensor over vehicular ai...

Northwest Arkansas has undergone a significant urban transformation in the past several decades and is considered to be one of the fastest growing regions in the United States. The urban area expansion and the associated demographic increases bring unprecedented pressure to the environment and natural resources. To better understand the consequences of urbanization, accurate and long-term depic...

HPLC-SPE-NMR analysis of a crude extract of fermentation broth of cultured PESTALOTIOPSIS VIRGATULA isolate TC-320 from TERMINALIA CHEBULA Retz. (Combretaceae) disclosed the presence of a simple but unprecedented low-molecular-weight metabolite, 9-hydroxybenzo[ C]oxepin-3[1 H]-one, subsequently isolated by a targeted purification procedure.

A hitherto unprecedented electronic situation has been observed for a substituted, pyridyl-functionalized phosphinine. In contrast to previous studies, this compound shows considerable π-donor properties as the result of the rather strong +M effect of the CH3S-substituent, changing the electronic properties of this low-coordinate and aromatic phosphorus heterocycle substantially.
