Due to the rapid development and widespread usage of various communication systems, multiband internal antennas are necessary for recent mobile handsets [1]-[3]. To meet the antenna requirement for hand-held terminal, the size reduction is one of the key requirements while maintaining the good multiband and wideband performance. Furthermore, a small intenna that can be integrated into the hands...

Eukaryotic microalgae and prokaryotic cyanobacteria are the major components of the phytoplankton. Determining factors that govern growth of these primary producers, and how they interact, is therefore essential to understanding aquatic ecosystem productivity. Over half of microalgal species representing marine and freshwater habitats require for growth the corrinoid cofactor B12, which is synt...

Abstract PURPOSE/METHODS: Clinical and molecular risk factors in 142 patients <5 years with desmoplastic medulloblastoma (DMB) or extensive nodularity (MBEN) were investigated. Patients diagnosed between 1992 2020 treated radiation-sparing approaches, 131 intraventricular methotrexate. 14 metastatic disease received high-dose chemotherapy. DNA methylation profiles of 77 sonic hedgehog (S...

Single photon ionization of C60 in 2,2-dimethylpropane (neopentane, NP), 2,2,4,4-tetramethylpentane (TMP), 2,2-dimethylbutane (neohexane, DMB), and 2,2,4-trimethylpentane (isooctane, isoOCT), and of C70 in TMP was studied by photoconductivity measurement. Threshold energies of the photoconductivity were determined. From these results, the polarization energies and the ionic radii of the cations...

Previous studies demonstrated that sphingosine-1-phosphate (S1P) phosphohydrolase 1 (SPP-1), which is located mainly in the endoplasmic reticulum (ER), regulates sphingolipid metabolism and apoptosis (H. Le Stunff et al., J. Cell Biol. 158:1039-1049, 2002). We show here that the treatment of SPP-1-overexpressing cells with S1P, but not with dihydro-S1P, increased all ceramide species, particula...

Assigning tasks to a set of robots is a fundamental problem in robotics. It consists in finding the best task assignment to the available robots. In this paper, we present two distributed market-based algorithms to solve the assignment problem where n robots compete for n tasks with the assumption that each robot can be assigned to only one task. The first algorithm, called DMB, represents a Di...

In this paper we study in detail the post-growth annealing of a copper-containing material deposited with focused electron beam induced deposition (FEBID). The organometallic precursor Cu(II)(hfac)2 was used for deposition and the results were compared to that of compared to earlier experiments with (hfac)Cu(I)(VTMS) and (hfac)Cu(I)(DMB). Transmission electron microscopy revealed the deposition...

This paper presents an overview of a satellite based broadcast layer to enhance the 3G and beyond 3G systems in the delivery of Multimedia Broadcast/Multicast Services (MBMS), as identified within the European IST integrated project MAESTRO. The foreseen content delivery architecture, also referred to as Satellite Digital Multimedia Broadcast (S-DMB) architecture, shall become an enabler for th...
