We consider the effect of lensing magnification on high redshift sources in the case that magnification varies on the sky, as expected in wide fields of view or within observed galaxy clusters. We give expressions for number counts, flux and flux variance as integrals over the probability distribution of the magnification. We obtain these through a simple mapping between averages over the obser...

Purpose: To demonstrate the corneal magnification using trypan blue in cataract surgery. Methods: Eight eyes of eight patients undergoing phacoemulsification with an intraocular lens implantation were enrolled in this study. After staining the anterior capsule with Trypan Blue 0.1% and performing the capsulorhexis, the excised anterior capsule was placed on the corneal surface. By observing and...

Vision researchers base their work on assumptions that lenses behave ideally. In practice the image formation process is complex and camera lenses have many non-ideal behaviors that can cause problems in simple vision tasks like color image analysis and range from focus. For example, unlike the ideal lens the refractive power of a real lens is actually a function of wavelength. This means that ...

We study the statistical properties of magnification perturbations by substructures in strong lensed systems using linear perturbation theory and an analytical substructure model including tidal truncation and a continuous substructure mass spectrum. We demonstrate that magnification perturbations are dominated by perturbers found within roughly a tidal radius of an image, and that sizable magn...

T he patient is a 65-year-old man with HIV/AIDS. In February 2016, he presented to an outside hospital with ascites (panel A; hematoxylin and eosin stain, original magnification3400) and a diagnosis ofMYC-rearranged (panel B) CD5–dimly positive (panel C) “aggressive large B-cell lymphoma.” There was no CD3 (panel D) or rearrangement of BCL2 or BCL6. He was treated and his ascites resolved, but ...

Objective: to analyze the organizational culture of a psychiatric hospital and identify the capacity of resilience of nursing workers. Method: quantitative research. For data collection, were used the Brazilian Instrument for Evaluation of Organizational Culture (IBACO - Instrumento Brasileiro para Avaliação da Cultura Organizacional) and the Resilience Scale (RS). Results: participants rep...
