We investigated the effects of different surface qualities of materials on vection strength. Previous studies have extensively examined the stimulus parameters for effective vection induction. However, the effects of surface qualities on vection induction have not been studied at all despite their importance in realistic perception of a scene. As a first step toward understanding the effects of...

Abstract Light is considered a factor that influences the seed germination of many weed species, and it can signal whether environmental conditions are favorable or not for germination. We aimed to study if there an influence light quality dormancy overcoming in Echium plantagineum L. carried out 2 x 6 factorial experiment, with without potassium nitrate followed by immersion gibberellic acid; ...

the accumulation and composition of berry anthocyanin was measured in vitis vinifera l. cv. yatomi rosa using various light qualities provided by polyethylene films (red, orange, green, blue, and white). the anthocyanin has been enhanced significantly by blue light filter film and suppressed by red, orange, and green films compared to white film (control), which suggests that yatomi rosa has ad...

This study examined the associations between relationship qualities, sexual behaviors, and relationship length in 61 adolescent couples (aged 16-20). For both male and female partners, positive relationship qualities were associated with physical expressions of affection. Perceptions of higher levels of conflict and frustration were associated with more frequent sexual intercourse. Factor analy...

We present a new interactive sound installation to be explored by movement. Specifically, movement qualities extracted from the motion tracking data excite a dynamical system (a synthetic flock of agents), which responds to the movement qualities and indirectly controls the visual and sonic feedback of the interface. In other words, the relationship between gesture and sound are mediated by syn...

The friendship paradox is a sociological phenomenon stating that most people have fewer friends than their friends do. The generalized friendship paradox refers to the same observation for attributes other than degree, and it has been observed in Twitter and scientific collaboration networks. This paper takes an analytical approach to model this phenomenon. We consider a preferential attachment...

Lasers are the principle light sources of flow cytometers. Most modern benchtop instruments feature air-cooled argon-ion laser emitting 10-25 mW of light at 488 nm. This unit covers the various types of lasers available and the qualities that make them suitable or unsuitable for use in flow cytometers. Also included is a discussion of future directions, particularly in the development of solid-...

0 0 The range of visible light lies between 4000 A and 7000 A wavelength. Extremely powerful radiation above and below those limits can be seen, but these are the commonly accepted extrema. Within that band the spectral distribution of power in a ray of light describes some of its qualities. The color that is perceived seems to be related to that spectral distribution. Two of the operations tha...
