Differential equations are fundamental tools in physics: they are used to describe phenomena ranging from fluid dynamics to general relativity. But when these equations become stiff (i.e. they involve ...

Can we reveal objects that are hidden in environments completely opaque to the human eye? With conventional imaging ...

Learning to play a musical instrument can protect your brain from aging, building up a defense against cognitive decline that lasts a lifetime. Researchers from Canada and China discovered older ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Extracting domains from email addresses can help analyze data, filter company-specific emails, and organize them for marketing or security purposes. If you have a database of email addresses and you ...

Every year, thousands of startups fight for unique names and domains. Your business name determines the way people perceive your brand — but without a matching domain, trust and discoverability ...

The inverse Fourier transform (inverse FFT or iFFT) reverses the operation of the Fourier transform and derives a time-domain representation from a frequency-domain dataset. Figure 1. The inverse ...

Introduction: Subjective visual impairment (VI) is related to cognition in cognitively unimpaired (CU) older adults, mild cognitive impairment (MCI) patients, and Alzheimer’s disease (AD) patients.

Abstract: This article proposes an inverse design method based on numerical Green’s function (NGF-IDM) to achieve the intelligent and efficient design of waveguide devices. Inspired by the metal ...

Objective: To determine the relationship between domain-specific physical activity (PA) (e.g., occupational PA [OPA], transport-related PA [TPA], and recreational PA [RPA]) and cognitive function in ...

The right side of the map in the Realm of Shadow has an area far below that's tough to reach. Here's how to get there. One of the last areas you might reach in the Shadow Realm is the area in the east ...
