A Static Kropki Puzzle Pattern‐Based Shade Dispersion Technique for a Partially Shaded Photovoltaic Array

Energy Science & Engineering
Partial shading is crucial in reducing the performance of the photovoltaic (PV) array. The static reconfiguration is a viable option for alleviating the partial shading. The scattering of shade relies on its puzzle pattern.

Expression of mutant TIE2 p.L914F during mouse development causes embryonic lethality and defects in vascular remodeling. [PDF]

Dev Dyn
Abstract Background Sporadic venous malformation (VM) is associated with the hyperactivating p.L914F mutation in TIE2, a receptor tyrosine kinase essential for vascular development. This mutation is not found in hereditary VM, suggesting incompatibility with life when expressed during early vascular development.
