The Relationships among Internalized Stigma, Sense of Coherence, and Personal Recovery of Persons with Schizophrenia Living in the Community
We investigated (i) the relationships among internalized stigma (IS), sense of coherence (SOC), and the personal recovery (PR) of persons with schizophrenia living in the community, and (ii) how to improve the support for these individuals. A questionnaire survey on IS, SOC, and PR was sent by mail to 270 persons with schizophrenia living in the community who were using psychiatric daycare services, of whom 149 responded and 140 were included in the analysis. We established a hypothetical model in which IS influences PR, and SOC influences IS and PR, and we used structural equation modeling to examine the relationships among these concepts. The goodness of fit was acceptable. Our findings suggest that rather than directly promoting PR, SOC promotes PR by mitigating the impact of IS. It is important for nurses/supporters to support individuals with schizophrenia living in the community so that they have opportunities to reflect on their own experiences through their activities and to share their experiences with peers. Nurses/supporters themselves should also reflect on their own support needs. Our findings suggest that this will lead to a reduction of IS and the improvement of SOC, which will in turn promote personal recovery
Edge-dominating cycles in graphs
AbstractA set S of vertices in a graph G is said to be an edge-dominating set if every edge in G is incident with a vertex in S. A cycle in G is said to be a dominating cycle if its vertex set is an edge-dominating set. Nash-Williams [Edge-disjoint hamiltonian circuits in graphs with vertices of large valency, Studies in Pure Mathematics, Academic Press, London, 1971, pp. 157–183] has proved that every longest cycle in a 2-connected graph of order n and minimum degree at least 13(n+2) is a dominating cycle. In this paper, we prove that for a prescribed positive integer k, under the same minimum degree condition, if n is sufficiently large and if we take k disjoint cycles so that they contain as many vertices as possible, then these cycles form an edge-dominating set. Nash-Williams’ Theorem corresponds to the case of k=1 of this result
Interplay between structure and magnetism in nanowires
We investigate the equilibrium geometry and electronic structure of
MoSI nanowires using ab initio Density Functional
calculations. The skeleton of these unusually stable nanowires consists of
rigid, functionalized Mo octahedra, connected by flexible, bi-stable sulphur
bridges. This structural flexibility translates into a capability to stretch up
to approximate 20% at almost no energy cost. The nanowires change from
conductors to narrow-gap magnetic semiconductors in one of their structural
isomers.Comment: 4 pages with PRL standards and 3 figure
A protocol to construct RNA-protein devices for photochemical translational regulation of synthetic mRNAs in mammalian cells
Here, we describe a protocol for the translational regulation of transfected messenger RNAs (mRNAs) using light in mammalian cells. We detail the steps for photocaged ligand synthesis, template DNA preparation, and mRNA synthesis. We describe steps for mRNA transfection, treatment of cells with a photocaged ligand followed by light irradiation, and analysis of the transgene expression. The protocol enables spatiotemporally regulated transgene expression without the risk of insertional mutagenesis
Prospect for Future MeV Gamma-ray Active Galactic Nuclei Population Studies
While the X-ray, GeV gamma-ray, and TeV gamma-ray skies have been extensively
studied, the MeV gamma-ray sky is not well investigated after the Imaging
Compton Telescope (COMPTEL) scanned the sky about two decades ago. In this
paper, we investigate prospects for active galactic nuclei population studies
with future MeV gamma-ray missions using recent spectral models and luminosity
functions of Seyfert and flat spectrum radio quasars (FSRQs). Both of them are
plausible candidates as the origins of the cosmic MeV gamma-ray background. If
the cosmic MeV gamma-ray background radiation is dominated by non-thermal
emission from Seyferts, the sensitivity of 10^-12 erg cm^-2 s^-1 is required to
detect several hundred Seyferts in the entire sky. If FSRQs make up the cosmic
MeV gamma-ray background, the sensitivity of ~4 x 10^-12 erg cm^-2 s^-1 is
required to detect several hundred FSRQs following the recent FSRQ X-ray
luminosity function. However, based on the latest FSRQ gamma-ray luminosity
function, with which FSRQs can explain up to ~30% of the MeV background, we can
expect several hundred FSRQs even with the sensitivity of 10^-11 erg cm^-2 s^-1
which is almost the same as the sensitivity goal of the next generation MeV
telescopes.Comment: 9 pages, 5 figures, accepted for publication in PAS
Detection of extended millimeter emission in the host galaxy of 3C273 and its implications for QSO feedback via high dynamic range ALMA imaging
We estimate the amount of negative feedback energy injected into the ISM of
the host galaxy of 3C273, a prototypical radio loud quasar. We obtained 93, 233
and 343 GHz continuum images with the Atacama Large Millimeter/Sub-millimeter
Array (ALMA). After self calibration and point source subtraction, we reach an
image dynamic range of at 93\ GHz, at 233\ GHz and
at 343\ GHz. These are currently the highest image dynamic range
obtained using ALMA. We detect spatially extended millimeter emission
associated with the host galaxy, cospatial with the Extended Emission Line
Region (EELR) observed in the optical. The millimeter spectral energy
distribution and comparison with centimeter data show that the extended
emission cannot be explained by dust thermal emission, synchrotron or thermal
bremsstrahlung arising from massive star formation. We interpret the extended
millimeter emission as thermal bremsstrahlung from gas directly ionized by the
central source. The extended flux indicates that at least of the
bolometric flux of the nuclear source was used to ionize atomic hydrogen in the
host galaxy. The ionized gas is estimated to be as massive as to
, but the molecular gas fraction with respect to the
stellar mass is consistent with other ellipticals, suggesting that direct
ionization ISM by the QSO may not be sufficient to suppress star formation, or
we are witnessing a short timescale before negative feedback becomes
observable. The discovery of a radio counterpart to EELRs provides a new
pathway to studying the QSO-host ISM interaction
