Evaluation of Upper-Limb Feeding Performance Using the Fugl–Meyer Assessment
No full textAbstract
Date Presented 3/30/2017
The Fugl–Meyer Assessment cutoff values to identify “can use spoon” and “can use chopsticks” were 54/53 and 62/61 points, with sensitivity and specificity of 86.7% and 96.4% and 100.0% and 97.1%, respectively. These optimal cutoff scores may be able to identify upper-limb feeding performance.

Infrared Emission from Intracluster Dust Grains and Constraints on Dust Properties
No full textFor 117 clusters of galaxies, we explore the detectability of intracluster dust grains by current and future infrared facilities, taking into account both collisional heating and sputtering of grains by the ambient plasma. If the dust grains are injected into intergalactic space with the amount and size comparable to the Galactic values, the dust-to-gas ratio is typically 10−6 and the mean dust temperature is ∼ 30K near the cluster center. The predicted infrared intensities lie marginally above the detection thresholds for Spitzer Space Telescope, ASTRO-F, Herschel, an
Sunyaev-Zeldovich Fluctuations From Spatial Correlations Between Clusters Of Galaxies
No full textWe present angular power spectra of the cosmic microwave background radiation anisotropy due to fluctuations of the Sunyaev-Zeldovich (SZ) effect through clusters of galaxies. A contribution from the correlation among clusters, which has been neglected in previous analyses, is especially focused on. Employing the evolving linear bias factor based on the Press-Schechter formalism, we find that the clustering contribution amounts to 20%--30% of the Poissonian contribution at degree angular scales. If we exclude clusters in the local universe, it even exceeds the Poissonian noise and makes the dominant contribution to the angular power spectrum. As a concrete example, we demonstrate the subtraction of the ROSAT X-ray and Planck SZ flux-limited cluster samples. It indicates that we should include the clustering effect in the analysis of the SZ fluctuations. We further find that the degree scale spectra essentially depend upon the normalization of the density fluctuations, i.e., j 8 , and t..
Formation of subgalactic clouds under ultraviolet background radiation
No full textapplication/pdfThe effects of the ultraviolet (UV) background radiation on the formation of subgalactic clouds are studied by means of one-dimensional hydrodynamical simulations. The radiative transfer of the ionizing photons caused by the absorption by H I, He I, and He II, neglecting the emission, is explicitly taken into account. We find that the complete suppression of collapse occurs for the clouds with circular velocities typically in the range Vc ~ 15-40 km s-1 and the 50% reduction in the cooled gas mass with Vc ~ 20-55 km s-1. These values depend most sensitively on the collapse epoch of the cloud, the shape of the UV spectrum, and the evolution of the UV intensity. Compared with the optically thin case, previously investigated by Thoul & Weinberg in 1996, the absorption of the external UV photons by the intervening medium systematically lowers the above threshold values by ΔVc ~ 5 km s-1. Whether the gas can contract or keeps expanding is roughly determined by the balance between the gravitational force and the thermal pressure gradient when it is maximally exposed to the external UV flux. Based on our simulation results, we discuss a number of implications on galaxy formation, cosmic star formation history, and the observations of quasar absorption lines. In the Appendix, we derive analytical formulae for the photoionization coefficients and heating rates, which incorporate the frequency/direction-dependent transfer of external photons.journal articl

No full textStability of line solitons for the KP-II equation in R2
No full textThe author proves nonlinear stability of line soliton solutions of the KP-II equation with respect to transverse perturbations that are exponentially localized as x\to\infty. He finds that the amplitude of the line soliton converges to that of the line soliton at initial time whereas jumps of the local phase shift of the crest propagate in a finite speed toward y=\pm\infty. The local amplitude and the phase shift of the crest of the line solitons are described by a system of 1D wave equations with diffraction terms

No full textMature seed dormancy is a vital plant trait that prevents germination out of season. In Arabidopsis, the trait can be maternally regulated but the underlying mechanisms sustaining this regulation, its general occurrence and its biological significance among accessions are poorly understood. Upon seed imbibition, the endosperm is essential to repress the germination of dormant seeds. Investigation of genomic imprinting in the mature seed endosperm led us to identify a novel set of imprinted genes that are expressed upon seed imbibition. Remarkably, programs of imprinted gene expression are adapted according to the dormancy status of the seed. We provide direct evidence that imprinted genes play a role in regulating germination processes and that preferential maternal allelic expression can implement maternal inheritance of seed dormancy levels
