Although previous studies show inconsistent results regarding the effect of depth perception on visual working memory (VWM), a recent finding shows that perceptually closer-in-depth items are better remembered than farther items when combining the congruent disparity and relative size cues. In this study, we employed a similar change detection paradigm to investigate the effects of saturation and brightness, alone or in combination with binocular disparity, on VWM. By varying the appearance of the memory items, we aimed to manipulate the visual salience as well as to simulate the aerial perspective cue that induces depth perception. We found that the change detection accuracy was significantly improved for brighter and more saturated items, but not for items solely with higher saturation. Additionally, combining saturation with the congruent disparity cue significantly improved memory performance for perceptually closer items over farther items. Conflicting the disparity cue with saturation eliminated the memory benefit for the closer items. These results indicate that saturation and brightness could modulate the effect of depth on VWM, and both visual salience and depth perception affect VWM possibly through a common underlying mechanism of setting priority for attentional selection.

In this work, three composite materials based on Terfenol-D and PZT-type material were obtained with a classic sintering method using a combination of 0-3 phases, where the ferroelectric phase was doped PZT material (P) and the magnetic phase was Terfenol-D (T). The percentage of P and T components in the composites was variable, i.e.

Crossmodal correspondences, or widely shared tendencies for mapping experiences across sensory domains, are revealed in common descriptors of musical timbre such as , , and . Two experiments are reported in which participants listened to recordings of musical instruments playing major scales, selected colors to match the timbres, and rated the timbres on crossmodal semantic scales. Experiment A used three different keyboard instruments, each played in three pitch registers.

Magnetic field-dependent magnetization of highly crystalline FeO magnetic nanoparticles has been carried out to understand surface canting structures at low and room temperatures. The exchange bias () values of ∼18 to 27 Oe at 300 K for three samples prepared from different precursors are observed; and a decrease in value is obtained when the samples are measured at 5 K. However, with a decrease in temperature, coercivity () increases.

Proper exposure settings are crucial for modern machine vision cameras to accurately convert light into clear images. However, traditional auto-exposure solutions are vulnerable to illumination changes, splitting the continuous acquisition of unsaturated images, which significantly degrades the overall performance of underlying intelligent systems. Here we present the neuromorphic exposure control (NEC) system.

The FabricSpotDefect dataset is, to the best of our knowledge, the first dataset specifically designed to accurately challenge computer vision in detecting fabric spots. There are a total of 1014 raw images and manually annotated 3288 different categories of spots. This dataset expands to 2300 augmented images after applying six categories of augmentation techniques like flipping, rotating, shearing, saturation adjustment, brightness adjustment, and noise addition.
