A Sparse Capture Light-Field Coding Algorithm Based on Target Pixel Matching for a Multi-Projector-Type Light-Field Display System

Photonics, 2023
The traditional light-field coding algorithm used in a multi-projector-type light-field display system requires sophisticated and complex three-dimensional modeling processes or parallax images obtained through dense capture. Here we propose an algorithm

Light Field Display Point Rendering

Proceedings of the ACM on Computer Graphics and Interactive Techniques
Rendering for light field displays (LFDs) requires rendering of dozens or hundreds of views, which must then be combined into a single image on the display, making real-time LFD rendering extremely difficult. We introduce light field display point rendering (LFDPR), which meets these challenges by improving eye-based point rendering [Gavane and Watson ...

Light field Mirage using multiple flat-panel light field displays

Optics Express, 2021
This study proposes a digital implementation of the conventional Mirage, which uses two parabolic mirrors to produce 360-degree three-dimensional (3D) images of real objects placed inside of it. The two mirrors are replaced with multiple light field displays to generate rays emitted from 3D objects in 360 degrees.

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

FEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

Multiscale Design and Simulation of CdSe/ZnS/MoTe₂ Hybrid Photodetectors

Sensors
Two-dimensional MoTe2 is applicable for near-infrared photodetection; however, low absorption in the visible range limits its performance. One way to overcome these limitations is by hybridizing with light-absorbing nanomaterials.

Large-scale metagrating complex-based light field 3D display with space-variant resolution for non-uniform distribution of information and energy

Nanophotonics, 2023
Glasses-free three-dimensional (3D) display has attracted wide interest for providing stereoscopic virtual contents with depth cues. However, how to achieve high spatial and angular resolution while keeping ultrawide field of view (FOV) remains a ...

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

FEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Dynamic optical chirality based on liquid-crystal-embedded nano-cilia photonic structures

Nature Communications
Compared to natural chiral molecules, artificial chiral photonic structures offer stronger chiroptical responses. However, the remarkable optical properties of most chiral structures are fixed upon fabrication, limiting their applications in scenarios ...
