Wireless sensor networks are at the crux of the Internet of Things applications. At the current state, there exist several technologies competing against each other in the IoT space. These proprietary technologies and hardware pose a serious problem of interoperability, which is vital to unleash the vision of the Internet of Things. Moreover, the traditional approach towards wireless sensor net...

PURPOSE The aim of this study was to retrospectively observe and analyze the long-term treatment outcomes of 191 elderly patients with esophageal squamous cell cancer (ESCC) who were treated with californium-252 (252Cf) neutron brachytherapy (NBT) in combination with external beam radiotherapy (EBRT). MATERIAL AND METHODS From January 2002 to November 2012, 191 patients with ESCC underwent NB...

PURPOSE The aim of this study was to retrospectively observe and analyze the long-term treatment outcomes of a total of 140 esophageal cancer patients who were treated with californium-252 ((252)Cf) neutron brachytherapy (NBT) in combination with external beam radiotherapy (EBRT) and concurrent chemotherapy (CCT). METHODS AND MATERIALS From January 2002 to November 2012, 140 patients with eso...

Several questions of importance in the study of lanthanide and actinide coordination compounds are reviewed. There is considerable evidence that in aqueous solution the primary coordination number is nine for the ions La(ni) through Nd(m) and eight for the ions heavier than Gd(m). While it seems that some degree of covalency exists in the metal—ligand bonding a model of electrostatic bonding se...

The quantification of Pu present, for example, as process hold-up in glove boxes or in waste containers may be accomplished by passive neutron coincidence counting (PNCC) to determine the Pu-240 effective mass which may then be related to the total Pu mass or Pu-239 mass through the isotopic composition. When multiplication can reasonably be taken as slight, assay results are normally based on ...

The discovery — or, rather, the synthesis — of lawrencium spanned several years and several experiments from two research teams, in Berkeley, USA, and in Dubna, Russia1. In 1961, the US-based team first reported the synthesis of an isotope of element 103. Mixed californium isotope targets 249,250,251,252Cf were bombarded with boron beams; the reaction products were caught by a metalized Mylar t...

Vaccinia virus growth factor (VGF), a highly glycosylated 77-residue epidermal growth factor (EGF)-like polypeptide encoded in vaccinia poxvirus, is reported to play an important role in stimulating growth of uninfected cells to facilitate virus infection. We have chemically synthesized the unglycosylated forms of VGF and VGF19-69, a shortened VGF analog consisting of 51 residues and comprising...

On the first of November 1952, in a top secret test known as Mike, the United States detonated the ‘Sausage’ — the world’s first hydrogen bomb. The explosion annihilated the entire Pacific island of Elugelab, but it wasn’t all devastation; at the same time it created two new elements that their discoverers would later name einsteinium and fermium. The explosion was colossal, being more powerful...
