Contrast sensitivity functions (CSFs) were measured in the foveal region while subjects simultaneously performed an instantaneous judgment task, which was designed to maintain their attended areas at a constant size. Spatial attention was sustained over areas that were either narrow (Narrow condition) or broad (Broad condition). We observed that the sensitivity at higher frequencies (over 3 cpd...

It is known that the spectral energy distribution (SED) of the nuclear radiation of narrow-line Seyfert 1 galaxies (NLS1s) has different shapes with respect to that of ordinary broad-line Seyfert 1 galaxies (BLS1s), particularly in wavelengths of X-ray. This may cause some differences in the ionization degree and the temperature of gas in narrow-line regions (NLRs) between NLS1s and BLS1s. This...

We report on the variability of the iron K emission line in the Seyfert 1 galaxy MCG– 6-30-15 during a four-day ASCA observation. The line consists of a narrow core at an energy of about 6.4 keV, and a broad red wing extending to below 5 keV, which are interpreted as line emission arising from the inner parts of an accretion disk. The narrow core correlates well with the continuum flux whereas ...

Most copepods exhibit one of three kinds of body architecture: 1) six broad anterior trunk somites and five narrow posterior trunk somites of gymnopleans; 2) five broad anterior trunk somites and six narrow posterior trunk somites of many podopleans; or 3) four broad anterior trunk somites and seven narrow posterior trunk somites of thaumatopsylloids. A phylogenetic analysis using naupliar and ...

This paper first summarizes some phonetic observations that challenge theories of speech perception and speech understanding which assume the speech signal is converted to an abstract form, such as features or phonemes, before it can be understood, and that ‘knowledge-driven’ processes are largely ‘top down’ rather than signal-driven. Systematic variation in fine phonetic detail is shown to ind...

An increase in the frequency and magnitude of extreme weather events, such as major ice storms, can have severe impacts on southern forests. We investigated the damage inflicted by a severe ice storm that occurred in February 2014 on two loblolly pine (Pinus taeda L.) ideotypes in Cross, South Carolina located in the southeastern coastal plain. The ‘‘narrow crown” ideotype allocates more resour...

abstract in order to study the inheritance of grain yield and its components in bread wheat, two cultivars, karchyya(drought and salinity tolerant) and gaspard (sensitive to drought and salinity stress) were crossed.parents together with f1, f2, f3, bc1and bc2 generations were evaluated using a randomized complete block design with three replications in 2008-2009 growing season.grain weight per...
