In subjects inspecting random polygonal shapes eye movements were recorded by means of a corneal reflection technique and computer processed. Eye fixations were mostly located around angles. Distribution of fixations over different angles was unhomogenous. Angular rotation changed both semantic meaning of the shapes and the eye fixation distribution. Sequential Markov dependence was found only in cases when semantic interpretation of the shapes was reported by the subjects and was absent when the shapes were perceived as meaning-less geometrical patterns.

Digital micromirror devices (DMDs), owing to their rapid refresh rates and ability to shape particular optical patterns, are key tools for holographic 3D near-eye displays. However, relying on a single-sideband (SSB) filter to eliminate crosstalk from zero-order and conjugate noise leads to an enormous decrease in the utilization of spatial bandwidth product (SBP). In this paper, we develop a new strategy for the binary hologram optimization framework to enable the full utilization of SBP of DMD holographic display by minimizing conjugate noise.

The contribution of sex hormones to cardiovascular disease, including arterial stiffness, is established; however, the role of sex chromosome interaction with sex hormones, particularly in women, is lagging. Arterial structural stiffness depends on the intrinsic properties and transmural wall geometry that comprise a network of cells and extracellular matrix (ECM) proteins expressed in a sex-dependent manner. In this study, we used four-core genotype (FCG) mice to determine the relative contribution of sex hormones versus sex chromosomes or their interaction with arterial structural stiffness.

The organ of Corti, located in the inner ear, is the primary organ responsible for animal hearing. Each hair cell has a V-shaped or U-shaped hair bundle composed of actin-filled stereocilia and a kinocilium supported by true transport microtubules. Damage to these structures due to noise exposure, drug toxicity, aging, or environmental factors can lead to hearing loss and other disorders.
