The number of people in Haiti who have fled their homes has risen threefold in the last year to more than one million, according to the United Nations. The UN’s International Organization for ...

Diffractive optical elements (DOEs ... Furthermore, the theoretical foundation for primary objective grating (POG) telescopy has been explored, which could revolutionize how telescopes collect ...

When chlorine (as a gas or dissolved in water) is added to sodium bromide solution, the chlorine takes the place of the bromine. Because chlorine is more reactive than bromine, it displaces ...

Children bear the greatest burden of displacement, making up over half of the displaced population. This marks a threefold increase in displacement within a year, rising from 315,000 in December 2023 ...

Internal displacement has long been a neglected issue on the international stage. But recent years have seen an uptick in policy momentum – spearheaded by the creation of a High-Level Panel on ...

A diffractive optic creates two DUV beams ... known as a “transient grating.” These patterns are sinusoidal, alternating between high and low energy, and allow researchers to study how ...

An external-cavity wavelength-swept laser, characterized by its exceptional temporal coherence and extensive tuning range, serves as a crucial light source for cutting-edge fields such as fiber ...

The aim of this review is to summarize the clinical outcomes reported in patients following the implantation of the hydrophobic diffractive trifocal FineVision HP intraocular lens (IOL). A literature ...
