We examined contrast sensitivity and suprathreshold apparent contrast with natural images. The spatial-frequency components within single octaves of the images were removed (notch filtered), their phases were randomized, or the polarity of the images was inverted. Of Michelson contrast, root-mean-square (RMS) contrast, and band-limited contrast, RMS contrast was the best index of detectability....

We report a single-layer frequency selective dual band reflectarray operated at 28 and 39GHz simultaneously. The consists of cross dipole spiral elements aligned on the surface substrate surfaces rear side. that can control reflection direction same plane substrate, resulting in simultaneous dual-band up to ±30° independently. Furthermore, showed higher transmittance frequencies except for targ...

Notch is a pleiotropic signaling family that has been implicated in pathogenesis of allergic airway diseases; however, the distinct function of individual Notch ligands remains elusive. We investigated whether Notch ligands, Jagged1 and DLL4, exert differential effects in OVA-induced allergic asthma. We found that whilst Jagged1 inhibition mitigated Th2-dominated airway inflammation, blockage o...

A six-pole Q-band waveguide filter with a notch frequency above the has been developed for plasma diagnostics. The previous paper [Nishiura et al., J. Instrum. 10, C12014 (2015)] reported that exists within standard band. In this study, newly required extends function, which prevents thorny wave from being mixed into an instrument beyond bandwidth of waveguide. mode control technique cavities r...

Much of the patterning of early C. elegans embryos involves a series of Notch interactions that occur in rapid succession and have distinct outcomes; however, none of the targets for these interactions have been identified. We show that the REF-1 family of bHLH transcription factors is a major target of Notch signaling in all these interactions and that most examples of Notch-mediated transcrip...

Asymmetric cell divisions generate sibling cells of distinct fates ('A', 'B') and constitute a fundamental mechanism that creates cell-type diversity in multicellular organisms. Antagonistic interactions between the Notch pathway and the intrinsic cell-fate determinant Numb appear to regulate asymmetric divisions in flies and vertebrates. During these divisions, productive Notch signaling requi...

A small size ultra-wideband (UWB) antenna having dimensions of 12x 19 mm 2 incorporated with dual bandrejected properties and good gain is recommended in this paper. The recommended antenna consists of a microstrip line fed rectangular-shaped patch with a circular slot on one side of FR4 substrate and rectangular DGS (Defected Ground Structure) on the other side. By etching a circle on the patc...
