Article Abstract
This paper proposes an open computer language (OpenCL) parallel processing method to generate the elemental image arrays (EIAs) for hexagonal lens array from a three-dimensional (3D) object such as a volume data. Hexagonal lens array has a higher fill factor compared to the rectangular lens array case; however, each pixel of an elemental image should be determined to belong to the single hexagonal lens. Therefore, generation for the entire EIA requires very large computations. The proposed method reduces processing time for the EIAs for a given hexagonal lens array. By using the proposed image space parallel processing (ISPP) method, it can enhance the processing speed that generates the 3D display of real-time interactive integral imaging for hexagonal lens array. In our experiment, we implemented the EIAs for hexagonal lens array in real-time and obtained a good processing time for a large of volume data for multiple cases of lens arrays.

This paper introduces a Hybrid Plasmonic Nano-Antenna (HPNA) with a gradient-index dielectric flat lens modeled with different materials to enhance and steer the radiation in a particular direction based on a phase shift array. Firstly, the design of hybrid plasmonic Nano-Antenna (NA) is introduced and analyzed considering different horn-shapes such as diamond, hexagonal, circular, rectangular, and square shapes. The commercial software Computer Simulation Technology-Microwave Studio (CST-MWS) is used to analyze the radiation characteristics of the plasmonic NAs at the standard telecommunication wavelength of 1,550 nm.

Disruption of Eph-ephrin bidirectional signaling leads to human congenital and age-related cataracts, but the mechanisms for these opacities in the eye lens remain unclear. Eph receptors bind to ephrin ligands on neighboring cells to induce canonical ligand-mediated signaling. The EphA2 receptor also signals non-canonically without ligand binding in cancerous cells, leading to epithelial-to-mesenchymal transition (EMT).

Article Synopsis
- - This study assessed how cataract surgery affects the corneal endothelium and central corneal thickness (CCT) in children, comparing results to a control group.
- - Results showed that after surgery, children with bilateral cataracts had a decrease in endothelial cell density (CD) and increases in average cell area (AVE) and CCT, while similar changes were observed in the unilateral cataract group.
- - The study also found that more corneal sutures and smaller pupil diameters correlated with worse corneal health outcomes in the unilateral cataract group.

Optical vortices have a topologically charged phase singularity and zero intensity distribution in the centre. Optical vortex creation is regarded as a significant means for information transmission for applications in quantum computing, encryption, optical communication, In this study, using finite-difference time-domain (FDTD) simulation, we calculated the electric field intensity and phase distribution of 2D lattices of optical vortices generated from various polygonal plasmonic lens structures using surface states of a Weyl semimetal (MoTe). It was shown that a hexagonal lens is the best performing plasmonic lens.

Article Synopsis
- A study was conducted to investigate the long-term effects of soft contact lens (SCL) usage on the corneas of Asian individuals, focusing on corneal endothelial density (ECD) and cell shape.
- The research analyzed data from nearly 9,000 patients who used SCLs for over a year, assessing various factors including age, sex, and duration of lens use.
- Findings showed that as the duration of SCL use increased, both ECD and the rate of hexagonal cells decreased, while the variation in cell size increased, highlighting the importance of regular eye check-ups for long-term SCL wearers.
