Circularly Polarized Structural Color Pigments Tunable Across the Full Visible Spectrum

open access: yesAdvanced Optical Materials, EarlyView.
By infusing black dye into spherical shells of polymerized cholesteric liquid crystal, blue, green and red omnidirectional retroreflectors of circularly polarized structural color are achieved. They can be laid out on arbitrary surfaces without any need for index matching binder to define graphical information for robots and Augmented Reality devices ...

The squint Moon and the witch ball

open access: yesNew Journal of Physics, 2015
A witch ball is a reflecting sphere of glass. Looking into the disk that it subtends, the whole sky can be seen at one glance. This feature can be exploited to see and photograph the squint Moon illusion, in which the direction normal to the illuminated ...

The Challenge of Illusory Perception of Animals: The Impact of Methodological Variability in Cross-Species Investigation

open access: yesAnimals, 2021
Although we live on the same planet, there are countless different ways of seeing the surroundings that reflect the different individual experiences and selective pressures.

On greek illusions: a semantic account of Alexopoulou’s generalization [PDF]

open access: yes, 2009
Alexopoulou (2008) argues that Greek provides new evidence for the concept of binding illusions that was hypothesized by Fox and Sauerland (1996). Of special interest from my perspective is Alexopoulou’s argument that binding illusions arise not only ...

Single‐Cell Transcriptomic Atlases of Camels and Cattle Unravel Molecular Evolution of Digestive and Metabolic Systems

open access: yesAdvanced Science, EarlyView.
We generated multi‐tissue single‐cell transcriptomic atlases of camels and cattle, uncovering conserved and lineage‐specific cellular features across digestive and metabolic systems. Cross‐species comparisons revealed the evolutionary origin of the camel glandular sac and identified novel cell populations linked to physiological specialization ...

A novel visual illusion paradigm provides evidence for a general factor of illusion sensitivity and personality correlates

open access: yesScientific Reports, 2023
Visual illusions are a gateway to understand how we construct our experience of reality. Unfortunately, important questions remain open, such as the hypothesis of a common factor underlying the sensitivity to different types of illusions, as well as of ...

Active Thermal Metasurfaces Enable Superscattering of Thermal Signatures Across Arbitrary Shapes and Thermal Conductivities

open access: yesAdvanced Science, EarlyView.
This study proposes a thermal superscatterer capable of manipulating thermal scattering signatures far exceeding the actual scale of objects. Utilizing transformation thermotics and active thermal metasurfaces, the device reproduces the thermal scattering signature of the enlarged thermal scatterer.

Introduction to the special issue on visual illusions [PDF]

open access: yesPsihologija, 2014
Sensory illusions have aroused surprise and interest since antiquity, because they demonstrate that our sensory systems may not always provide reliable information about the world. In this special issue on illusions several teams of authors have

Susceptibility to optical illusions varies as a function of the autism-spectrum quotient but not in ways predicted by local–global biases [PDF]

open access: yes, 2016
Individuals with autism spectrum disorder and those with autistic tendencies in non-clinical groups are thought to have a perceptual style privileging local details over global integration.

Wafer Scale III‐Nitride Deep‐Ultraviolet Vertical‐Cavity Surface‐Emitting Lasers Featuring Nanometer‐Class Control of Cavity Length

open access: yesAdvanced Science, EarlyView.
A DUV‐VCSEL strategy featuring the nanometer‐class control of the cavity length is proposed in the DUV optoelectronic framework based on GaN templates. After the sapphire removal, a self‐terminated etching technology is developed, whereby the cavity length can be accurately determined by epitaxy instead of the fabrication process. As such, a record low
