Spontaneous focus on numerosity in parents of preschoolers: Is it related to the math input they provide?

There is substantial variability among parents in the amount of math input they provide at home, which is related to differences in children's early math knowledge. The current study examined whether parents' spontaneous focus on numerosity (SFON) predicts the math input they provide at home-in terms of both their math talk and frequency of math activities. Parents (N = 124) from diverse socioeconomic backgrounds in China were presented with a SFON picture task.

Development of photoactive ZnS-SiO composites on biogenic silica matrix for organic pollutant degradation.

Sulfide ZnS-SiO composite photocatalysts with biogenic silica matrix were prepared by sol-gel method based on wet gel and xerogel. FT-IR, SEM, XRD, EDXRF, UV-Vis, and XPS methods were systematically used to characterize the obtained materials. The use of support allowed to obtain stable porous (S = 79-105 m g; V = 0.

[Prognosis criteria of optical coherence tomography angiography for the long-term efficacy of anti-VEGF therapy of neovascular age-related macular degeneration].

Purpose: The study aimed to determine the most significant optical coherence tomography angiography (OCTA) parameters in terms of predicting anti-VEGF therapy effectiveness during long-term (3-year) follow-up of patients with neovascular age-related macular degeneration (nAMD).

Material And Methods: The study included 122 patients (122 eyes) with mean age of 73.4±6.
