Summary: Recent advances in autostereoscopic three-dimensional (3D) display systems have led to innovations in consumer electronics and vehicle systems (e.g., head-up displays). However, medical images with stereoscopic depth provided by 3D displays have yet to be developed sufficiently for widespread adoption in diagnostics. This paper proposes a novel glasses-free 3D autostereoscopic display system based on an eye tracking algorithm and explores its viability as a 3D navigator for cardiac computed tomography (CT) images. The proposed system was trialed by expert readers, who identified key artery structures faster than with a conventional two-dimensional display without reporting any discomfort or 3D fatigue. With the proposed autostereoscopic 3D display systems, the 3D medical image navigator system has the potential to facilitate faster diagnoses with improved accuracy.

Summary: Autostereoscopic three-dimensional measuring systems are portable and fast precision metrology instruments that use integral imaging to observe measured parts from multiple perspectives. In order to improve the accuracy of depth estimation, an adaptive focus volume aggregation method based on convolutional neural networks is proposed. Experimental results show that this method significantly reduces noise and retains more accurate surface profiles.

Summary: In this paper, a novel augmented reality autostereoscopic 3D display based on sparse reflection array (SRA) is proposed. By utilizing a transparent LED display panel and a periodic SRA, the proposed display achieves a seamless fusion of real 3D objects and virtual 3D images. It offers higher light transmittance and thinner thickness compared to traditional autostereoscopic 3D displays based on parallax barrier or lenticular lens barrier. Experimental results demonstrate its superior display performance compared to conventional AR autostereoscopic 3D displays. This simple and versatile display can be applied in large-scale AR exhibition systems, glass curtain walls, and outdoor advertisements.

Summary: This paper presents a novel algorithm for the continuous projection of point triangles belonging to a triangle mesh. The algorithm utilizes the normals defined at the vertices of the triangle for projection and allows the projection direction to vary continuously on the mesh. Additionally, an optimized version of the algorithm is introduced to reduce calculation time. This algorithm can be effectively used for projecting a large set of points onto a coarse mesh.

Summary: This study presents analytical and experimental results of microstructuring movie theater metallic screens to maintain the polarization state of reflected light and control light intensity distribution. Solutions of surface functions with axial symmetry producing isotropic and Lambertian scattering were derived, along with diffraction modeling ranging from microns to hundreds of microns. Challenges associated with tiling and manufacturing of such kernels were also discussed.

Summary: Researchers developed a high-throughput DNA or RNA labeling technology called HiDRO, enabling the quantitative measurement of chromatin interactions in single cells. By screening the human druggable genome, they identified over 300 factors that influence genome folding during interphase, with 43 genes validated to increase or decrease interactions between topologically associating domains. Inhibition of the kinase GSK3A was found to increase long-range chromatin looping interactions in a genome-wide and cohesin-dependent manner. These findings highlight the importance of GSK3A signaling in nuclear architecture and demonstrate the utility of HiDRO for identifying mechanisms of spatial genome organization.

Summary: A new method for axial 3D shape measurement using parallel single-pixel imaging is proposed in this paper, encoding depth through the projection of light transport coefficients and using third-order polynomial fitting for depth mapping and calibration. Experimental results demonstrate that the method can achieve robust, dense reconstruction with high depth accuracy and accuracy.

Summary: This study investigated the effects of autostereoscopic visual training on dynamic accommodative response, accommodative amplitude, and accommodative facility in myopic patients. The results showed that autostereoscopic visual training led to a decrease in accommodative lag and an increase in accommodative facility, but the long-term effects still require further exploration.
