Topological Radicals of Nest Algebras [PDF]
arXiv, 2016 Let N be a nest on a Hilbert space H and AlgN the corresponding nest algebra. We determine the hypocompact radical of AlgN . Other topological radicals are also characterized.

Nature, 1886 MR. MADAN in his amusing letter last week (p. 533) raises a point which has doubtless often caused the comments of teachers. I think “a partical of reasoning” at least can be adduced in favour of “radical.” In this paradoxical world it is not surprising to find that “radical” is the “conservative” and “constitutional” spelling, and that “radicle” is a ...

Oxygen Activation and Radical Transformations in Heme Proteins and Metalloporphyrins
Chemical Reviews, 2017 As a result of the adaptation of life to an aerobic environment, nature has evolved a panoply of metalloproteins for oxidative metabolism and protection against reactive oxygen species. Despite the diverse structures and functions of these proteins, they

Ag nanoparticle-enhanced alkyl radical generation in photopolymerization for holographic recording
Nanophotonics, 2019 We report a new Ag nanoparticle-dispersed polymer nanocomposite for volume holographic recording through acrylic photopolymerization. The initial grating buildup dynamics at the inhibition stage are measured at various Ag nanoparticle concentrations. The

Popular songs, social struggles and conflictual identities in Mestre-Marghera (1970s-1980s) [PDF]
, 2010 Through the analysis of popular song the chapter examines some of the ways in which local radical identities have been transformed as a result of changes in radical cultural practices in Mestre-Marghera, the industrial district in the mainland of ...

Molecular Oncology, EarlyView.Urine is a rich source of biomarkers for cancer detection. Tumor‐derived material is released into the bloodstream and transported to the urine. Urine can easily be collected from individuals, allowing non‐invasive cancer detection. This review discusses the rationale behind urine‐based cancer detection and its potential for cancer diagnostics ...

Subpar reporting of pre‐analytical variables in RNA‐focused blood plasma studies
Molecular Oncology, EarlyView.Pre‐analytical variables strongly influence the analysis of extracellular RNA (cell‐free RNA; exRNA) derived from blood plasma. Their reporting is essential to allow interpretation and replication of results. By evaluating 200 exRNA studies, we pinpoint a lack of reporting pre‐analytical variables associated with blood collection, plasma preparation ...

Diffusive vs. non-diffusive paths to interstellar hydrogen peroxide. A machine learning-based molecular dynamics study [PDF]
arXivContext. Radical chemical reactions on cosmic dust grains play a crucial role in forming various chemical species. Among different radicals, the hydroxyl (OH) is one of the most important ones, with a rather specific chemistry. Aims. The goal of this work is to simulate the recombination dynamics of hydroxyl radicals and the subsequent formation of ...

On Radicals of Semirings and Related Problems [PDF]
arXiv, 2012 The aim of this paper is to develop an `external' Kurosh-Amitsur radical theory of semirings and, using this approach, to obtain some fundamental results regarding two Jacobson type of radicals --- the Jacobson-Bourne, J-, radical and a very natural its variation, J_{s}-radical --- of hemirings, as well as the Brown-McCoy, R_{BM}-, radical of hemirings.
