After you pass the milestone age of 40, you'll notice it's more difficult to focus on objects up close. This is because thelens inside the eyebegins to lose its ability to change shape — a process called presbyopia. For a time, you can compensate for this gradual decline in focusing ...
Contact lensdiscomfort:Some pregnant women who wear contact lenses report discomfort, most likely due to changes in the shape of the cornea, which make contact lenses difficult to fit on the eye. During pregnancy, fluid retention can make the cornea less sensitive, especially during the third tri...
An electron gun has one first-type electron lens in the focusing electrode which changes the cross-sectional shape of the electron beam into a nonaxisymmetric shape with increase in the degree of the electron beam deflection by applying a first voltage varying in synchronism with deflection, and ...
1b). Interestingly, while in HC organoids KI67+ cells were mostly confined to the inner part of the VLZ, these cells were more broadly distributed in C9 organoids. Quantitative PCR (qPCR) showed comparable expression for the neuronal cytoskeleton marker TUBB3 and early born neuron marker DCX ...
These improvements have been driven by the potential to correct these aberrations using either contact lenses or through refractive surgery (corneal ablation and intraocular lens implants). Despite these improvements, predictions of visual performance have often not been successful, largely because of ...
Information and Communication Technologies (ICTs) can provide rich learning opportunities in classroom teaching, which requires teachers’ effective instrumental orchestrations. However, there is a lack of research regarding the development of teachers’
The widespread use of nano-biomaterials (NBMs) has increased the chance of human exposure. Although ingestion is one of the major routes of exposure to NBMs, it is not thoroughly studied to date. NBMs are expected to be dramatically modified following th
Groundwater dynamics are often overlooked within historical climatology because of their complexity and the influence of multiple factors. This study presents a groundwater model for Spain, using an existing tree-ring based summer drought reconstruction
Highly multiplexed imaging holds enormous promise for understanding how spatial context shapes the activity of the genome and its products at multiple length scales. Here, we introduce a deep learning framework called CAMPA (Conditional Autoencoder for M
This research investigates the dynamic interplay between land use changes and landscape ecological risks in China’s Jiangsu Province, specifically focusing on the Huai River-Gaoyou Lake region. Leveraging multi-temporal remote sensing data from 2000 to 2020, we conducted a comprehensive analysis of shi...
