Controlling Light Harvesting with Light [PDF]

open access: yesJournal of the American Chemical Society, 2016
When exposed to intense sunlight, all organisms performing oxygenic photosynthesis implement various photoprotective strategies to prevent potentially lethal photodamage. The rapidly responding photoprotective mechanisms, occurring in the light-harvesting pigment-protein antennae, take effect within tens of seconds, while the dramatic and potentially ...

When does grouping happen? [PDF]

open access: yes, 2003
Recent research on perceptual grouping is described with particular emphasis on identifying the level(s) at which grouping factors operate. Contrary to the classical view of grouping as an early, two-dimensional, image-based process, recent experimental ...

Mechanism of color change of flexible metafilm with structural parameters and stretching methods

open access: yesMaterials Research Express, 2022
Color change metafilm is promising for the color printing of displays and imaging. A metallic array on an elastic film can realize dynamic color change by mechanical extensions, such as uniaxial or biaxial stretching.

The interaction of Light with Matter and Light with Light [PDF]

open access: yes, 2020
This work consists of two fields of study involving the interaction of light with matter and light with light. The frst part explores the interaction of a superintense laser pulse with an ultrathin solid density foil. The radiation pressure exerted by the laser pulse can be so strong that, in principle, the whole foil is accelerated.

Effect of magnetized water and magnetic field treatments on the physicochemical properties, total phenolic and antioxidant capacity of sprouted oats flour [PDF]

open access: yesفناوری‌های جدید در صنعت غذا
One proposed method for optimizing water use in agriculture is to pass irrigation water through a magnetic field. In this study, the impacts of magnetized water and magnetic field treatments on the moisture and ash contents, pH, acidity, color indices ...

Chromatic Anchoring of Lightness

open access: yes, 2022
This study introduces a new, fundamental determinant of colour appearance: chromatic anchoring. We tested whether observers use the chromaticity of colours to anchor the colour gamut and estimate lightness (chromatic anchoring of lightness).

The role of amodal surface completion in stereoscopic transparency

open access: yesFrontiers in Psychology, 2012
Previous work has shown that the visual system can decompose stereoscopic textures into percepts of inhomogeneous transparency. We investigate whether this form of layered image decomposition is shaped by constraints on amodal surface completion.

Does age determine the lightness and darkness of tooth shades? A retrospective study

open access: yesJournal of Advanced Pharmaceutical Technology & Research, 2022
The study aimed to analyze whether age determines the lightness and darkness of tooth shades. The demand for esthetics has soared to a next level progressively in many developing countries including India; the importance provided to match the tooth shade
