Linear perspective served as a useful tool in the pursuit of verisimilitude in early modern art. But the technique’s enduring appeal among visual artists from this period did not stem from its ability to transcribe the world’s appearance alone. Rather, as this Reflection highlights, it was the perspectival image’s capacity to build a direct, one-to-one rapport with a viewer that most excited art practitioners. Painters like Piero della Francesca and Giovanni Bellini took full advantage of linear perspective’s potential for simulating vision. The spaces they constructed in altarpieces and other devotional imagery often showed supernatural realms that clearly defy human optical function. This essay presents several examples of early modern works that evoke spiritual vision through linear perspective constructions.

The bathypelagic alepocephalid teleost Bajacalifornia drakei has large eyes with sighting grooves and rostral aphakic gaps. An object in front of the fish will be imaged in both eyes through the full aperture of the lens in the temporal periphery of the retina, where a convexiclivate fovea with a prominent fovea externa is located. The fovea externa is composed of many banks of rods, up to 28 in a 39 mm specimen, compared with two banks in the peripheral retina. Estimates of foveal rod outer segments, nuclei and synaptic spherules show that there are almost twice as m any outer segments as nuclei, and that the number of spherules is much fewer than either. It is likely that new banks of rods are added to the retina, disproportionately m any in the fovea, as the fish grows. The paucity of synapses suggests that m any rods lose contact with bipolar cells, which may make new contacts with successive banks of rods. The possible mechanism of formation of the new banks, consequences of the multiple bank arrangement, and optical function of the fovea are discussed.

ABSTRACTIn this work we propose an analytical expression for the complex dielectric function that includes both discrete and continuum exciton effects. The model is based on the work of Elliott and the proposed model has been applied to modeling the experimental data for the hexagonal GaN. We have obtained good agreement with the experimental data. The model assumes Lorentzian broadening in order to obtain dielectric function equations in analytically closed form. We show that Lorentzian broadened dielectric function decays more slowly than the experimental data for hexagonal GaN at the low energy side. This indicates that the broadening of the absorption edge in GaN is not purely Lorentzian. The agreement with the experimental data can be improved using adjustable broadening modification.

Human eyes convey a remarkable variety of complex social and emotional information. However, it is unknown which physical eye features convey mental states and how that came about. In the current experiments, we tested the hypothesis that the receiver’s perception of mental states is grounded in expressive eye appearance that serves an optical function for the sender. Specifically, opposing features of eye widening versus eye narrowing that regulate sensitivity versus discrimination not only conveyed their associated basic emotions (e.g., fear vs. disgust, respectively) but also conveyed opposing clusters of complex mental states that communicate sensitivity versus discrimination (e.g., awe vs. suspicion). This sensitivity-discrimination dimension accounted for the majority of variance in perceived mental states (61.7%). Further, these eye features remained diagnostic of these complex mental states even in the context of competing information from the lower face. These results demonstrate that how humans read complex mental states may be derived from a basic optical principle of how people see.
