Interrogating an object with a light beam and analyzing the scattered light can reveal kinematic information about the object, which is vital for applications ranging from autonomous vehicles to gesture recognition and virtual reality. We show that by analyzing the change in the orbital angular momentum (OAM) of a tilted light beam eclipsed by a moving object, lateral motion of the object can b...

A novel white light-promoted reaction using photoluminescent nanocrystalline silicon enables the hydrosilylation of alkenes and alkynes, providing stabilization of the porous silicon without significant loss of the photoemissive qualities of the material. Photopatterning and lithographic fabrication of isolated porous silicon structures are made possible. Experiments and observations are presen...

Long-term effects of light quality on leaf hydraulic conductance (K(leaf)) and stomatal conductance (g(s)) were studied in cucumber, and their joint impact on leaf photosynthesis in response to osmotic-induced water stress was assessed. Plants were grown under low intensity monochromatic red (R, 640 nm), blue (B, 420 nm) or combined red and blue (R:B, 70:30) light. K(leaf) and g(s) were much lo...

Tissue cultures of Phyllanthus tenellus Roxb. were maintained on modified MS to evaluate in vitro flowering under light of different qualities: white (control), blue, green, red, yellow, UV-A plus white and darkness; as well as different growth regulators at concentrations (μM): IBA 0.98, KIN 0.46, KIN 2.3, IBA 0.98 + KIN 0.46, IAA 1.14 + KIN 0.46. The events from vegetative to reproductive gro...

Humans are able to estimate light field properties in a scene in that they have expectations of the objects' appearance inside it. Previously, we probed such expectations in a real scene by asking whether a "probe object" fitted a real scene with regard to its lighting. But how well are observers able to interactively adjust the light properties on a "probe object" to its surrounding real scene...

Beer brewing is an intricate process encompassing mixing and further elaboration of four essential raw materials, including barley malt, brewing water, hops and yeast. Particularly hops determine to a great extent typical beer qualities such as bitter taste, hoppy flavour, and foam stability. Conversely, hop-derived bitter acids account for an offending lightstruck flavour, which is formed on e...

This paper presents some results of the flight test campaign conducted on the Tecnam P2006T aircraft, on the occasion of its certification process. This twin-engine propeller airplane is certified under the normal category CS-23 and FAR 23. A prototype of this light aircraft has been tested in flight for a post-design performance optimization and for the assessment of flight qualities. These ex...

The discussions which follow have the aim of giving scientific expression to a psychological problem often noticed in philosophy but not yet, as we believe, made fully precise. Our task-already intimated in the title in the employment of an unusual and therefore only partially intelligible termcan be characterized briefly as one of explaining and defining the new concept signalled by this term ...

Seventeenthand eighteenth-century discussions of the senses are often thought to contain a profound truth: some perceptible properties are secondary qualities, dispositions to produce certain sorts of experiences in perceivers. Any apparent plausibility this has often derives, we argue, from an erroneous picture of perception. The colors are typically held to be one of the clearest examples of ...
