Wavelength and Full‐Polarization Encrypted Orbital Angular Momentum Meta‐Holography
Laser &Photonics Reviews, EarlyView.By multiplexing three independent degrees of freedom of light, a single‐layer geometric‐phase metasurface encrypts 24 distinct holographic images across 3 wavelengths, 12 pairs of orthogonal polarizations, and 4 OAM channels, taking advantage of axial chromatic dispersion to reconstruct the color images at the same plane. ABSTRACT Multiplexing multiple

Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model
Systems Research and Behavioral Science, EarlyView.ABSTRACT This paper advances a conceptual and mathematical foundations approach by applying the throughput model (TPM) to cosmic phenomena, reframing the universe as an extended information processing system. TPM's four stages, Perception, Information, Judgement and Decision Choice, are reformulated in explicit information‐theoretic and dynamical ...

From Particle to Purpose: A Systems‐Theoretical Model of Unity and Coherent Adaptation
Systems Research and Behavioral Science, EarlyView.ABSTRACT This paper develops a conceptual integration that bridges classical systems theories with insights from the Islamic intellectual tradition, focusing on the notion of zerre (particle) as articulated by Said Nursî. We reinterpret zerre as a systems‐theoretical agent that exhibits lawful responsiveness without autonomy, offering a new lens on how

Study on Impurity Particle Detection in Transformer Oil Based on Microflow Imaging Method
High Voltage, EarlyView.ABSTRACT The concentration of particles in transformer oil has a significant influence on its electrical performance, making oil cleanliness a critical parameter in the operation and maintenance of power transformers. However, the light obstruction (LO) method recommended by current standards has inherent limitations, including low sensitivity to ...

A new low-cost, compact, auto-phoropter for refractive assessment in developing countries
Scientific Reports, 2017 Using a phoropter to measure the refractive error is one of the most commonly used methods by ophthalmologists and optometrists. Here, we demonstrate design and fabrication of a portable automatic phoropter with no need for patient’s feedback. The system
