Uncorrected refractive error [PDF]
We need to act now to eliminate preventable blindness by the year 2020 In 1997, the World Health Organization set itself an ambitious goal to eliminate avoidable blindness in the world by 2020, with one of the five main priorities being refractive errors.1,2 A recent review of the impact of Vision 2020 on preventable blindness, other than uncorrected ...

This work addresses the challenge of current–voltage asymmetry in scalable laminated semitransparent organic photovoltaics (OPVs) for indoor applications. Vertical stratification of materials is shown to create an energy barrier, leading to performance differences under different illumination directions.

Studies of Relation Between Turbidity and Refractive Indeks of Bottled Water in the Area of Banda Aceh by Using Interferometer Murty Method [PDF]
Bottled water is clean water ready to drink quickly without cooking however, it is not all of the bottled water have a good quality. The quality of water can be observed from the optical properties of water, such as clarity and refractive index.

Synthetic cells are engineered herein to respond to an external chemical messenger by the activation of intracellular catalysis. The chemical messenger molecules are catalytically generated by an extracellular enzyme or a mineral surface, whereas the intracellular catalysis emerges via direct enzyme activation or via protein refolding.

A photocurable latex system enables high‐resolution vat photopolymerization of water‐dispersed thermoplastics, yielding pseudothermoplastic materials with recyclability. The formulation permits precise control over mechanical properties and supports reprocessing through conventional and extrusion‐based methods. Compatibility with two‐photon 3D printing

Autonomous Orbit Determination Using Epoch-Differenced Gravity Gradients and Starlight Refraction [PDF]
Autonomous orbit determination via integration of epoch-differenced gravity gradients and starlight refraction is proposed in this paper for low-Earth-orbiting satellites operating in GPS-denied environments. The starlight refrac-tion can compensate for the significant along-track position error using solely gravity gradients and benefit from the ...
