Investigation of a more optimum trajectory than the logarithmic spiral in solar sailing
, 2012 A logarithmic spiral trajectory is not the optimum trajectory for a solar sailing space vehicle. Investigation of the governing equations showed that the performance of the solar sail depends on one parameter "a".

TRIM Expression and Its Association With Disease Activity in Systemic Lupus Erythematosus
The Kaohsiung Journal of Medical Sciences, EarlyView.ABSTRACT Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with diverse manifestations, including rash, arthritis, and nephritis. Although autoantibodies are a key feature of SLE, their levels often poorly reflect disease severity, suggesting the involvement of additional contributing factors.

Stability Analysis on Shallow Layer Failure of Soil Slope Based on Unsaturated Soil Strength Theory
工程科学与技术, 2019 Based on unsaturated soil strength theory, a discriminant equation is established for the critical failure state of soil element in slope, and a combined failure mode of " upper and lower edge parallel slope curved surface” for soil slope is proposed ...

Metasurface‐Based Polarization‐Controlled Generation of 128‐Dimensional Vector Vortex Combs
Laser &Photonics Reviews, EarlyView.The generation and continuous control of 128‐dimensional vector vortex combs using a single metasurface is reported. This work creates a class of structured light that uniquely integrates ultrahigh dimensionality with vector properties, and represents a crucial step toward on‐chip, reconfigurable generators for ultrahigh‐dimensional vector structured ...

Laser &Photonics Reviews, EarlyView.An array of SiOx nanopillars is developed on ITO transparent rear contacts through nanoimprint lithography to promote light scattering in 500–600 nm bifacial ACIGS solar cells. This architecture increases the short‐circuit current density by 7.8 and 7.6 mA cm−2 under front (up to 36.2 mA cm−2) and rear illumination, respectively, offering a scalable ...
