Off‐Grid Solar Systems: An Experimental Work and Systematic Techno‐Economic Analysis

Energy Science &Engineering, EarlyView.
In the study mentioned above, experimental monitoring and economic evaluation of two off‐grid PV systems were conducted using a low‐cost data logger. The results suggest that basic DC systems are economically feasible compared to grid power, but that AC systems require further cost‐cutting to achieve financial viability.

Ultralow‐Backscattering Induced Mode Splitting in Chipscale Valley Photonic Topological Cavities

Laser &Photonics Reviews, EarlyView.
The proposed in‐situ metrology based on mode splitting quantifies the ultralow backscattering of topological valley edge states at a single sharp corner, demonstrating near‐lossless topological transport (0.09 dB/corner) on a silicon chip. This work provides insight into the robustness of the photonic valley system and shows the great potential of ...

Clinical, Genetic, and Imaging Characteristics of SCA27B: Insights from a Large Dutch Cohort

Movement Disorders, EarlyView.
Abstract Background Deep intronic GAA repeat expansions in intron 1 of the FGF14 gene were identified in 2023 as cause of late‐onset cerebellar ataxia. Since then, GAA‐FGF14‐related ataxia (SCA27B) has emerged as one of the most common genetic causes of late‐onset cerebellar ataxia.
