Extremely Red Galaxies at z=5-9 with MIRI and NIRSpec: Dusty Galaxies or Obscured Active Galactic Nuclei?

We study a new population of extremely red objects (EROs) recently discovered by the James Webb Space Telescope (JWST) based on their NIRCam colors F277W - F444W > 1.5 mag. We find 37 EROs in the Cosmic Evolution Early Release Science Survey (CEERS) field ...

A remarkable new Agestrata Eschscholtz, 1829 from Myanmar (Coleoptera, Scarabaeidae, Cetoniinae)

Michele De Palma

A new species in the genus Agestrata Eschscholtz, 1829 is described from Myanmar. The new taxon, Agestrata fortii n. sp., is markedly different from the other members of the genus. Further to the uniform turquoise-cerulean blue color of the integument, A. ...

Discomfort glare from daylight: Influence of transmitted color and the eye's macular pigment

Sneha Jain

Designing architectural façades that allow sufficient daylight to create visually comfortable and pleasant environments is a challenging aspect of building design. It requires accounting for visual comfort and discomfort glare risks and understanding the f ...

Comparison between CIE 2° and 10° field photopic luminosity functions V(λ) for calculating daylight discomfort glare metrics

Marilyne Andersen, Jan Wienold, Sneha Jain

The spectral sensitivity of the average human eye in photopic conditions is represented by the photopic luminosity function V (λ). The CIE has established the photopic luminosity functions for the 2o and 10o visual fields for a standard observer applicable ...

Oxidative Print Light Synthesis Thin Film Deposition of Prussian Blue

Hubert Girault, Emad Oveisi, Mounir Driss Mensi, Victor Costa Bassetto, Wanderson Oliveira Da Silva, Dominika Baster

Prussian blue (PB) and Prussian blue analogues (PBAs) are commonly synthesized by conventional methods, such as chemical precipitation, thermal decomposition, and electrochemical deposition. Herein, we have successfully synthesized Prussian blue by oxidati ...

A General Framework for Pearlescent Materials

Wenzel Alban Jakob, Ibon Guillen Serrano

The unique and visually mesmerizing appearance of pearlescent materials has made them an indispensable ingredient in a diverse array of applications including packaging, ceramics, printing, and cosmetics. In contrast to their natural counterparts, such syn ...

Oxidative Fluorination of Cyclopropylamides through Organic Photoredox Catalysis

Jérôme Waser, Mingming Wang

We report an oxidative ring-opening strategy to transform cyclopropylamides and cyclobutylamides into fluorinated imines. The imines can be isolated in their more stable hemiaminal form, with the fluorine atom installed selectively at the gamma or delta po ...

The role of one-shot learning in #TheDress

Michael Herzog, Adrien Christophe Doerig, Leila Drissi Daoudi - Kleinbauer

The first amazing effect with #TheDress is that a large number of people perceive it as white and gold even though the true colors of the dress are black and blue. Such apparent changes in color are common in many illusions. What makes #TheDress even more ...

The role of one-shot learning in #TheDress

Michael Herzog, Adrien Christophe Doerig

#TheDress is remarkable in two aspects. First, there is a bimodal split of the population in the perception of the dress's colors (white/gold vs. black/blue). Second, whereas interobserver variance is high, intra-observer variance is low, i. e., the percep ...

Nanostructuring and lattice dynamics of materials by femtosecond lasers

Ahmad Odeh

Physically, the colour of an object is a complex result of its intrinsic surface properties, its transmission properties and its emission properties, all of which contribute to the mix of wavelengths in the light leaving the surface of the object. Structur ...
