Fluid dynamics is the study of the motion of liquids, gases and plasmas. Flow is dependent on the intrinsic properties of the matter itself, such as compressibility, viscosity and density.

This paper reviews the methods, benefits and challenges associated with the adoption and translation of computational fluid dynamics (CFD) modelling within cardiovascular medicine. CFD, a specialist ...

Physics is the search for and application of ... Overcrowding can lead to disaster, and yet the dynamics of dense groups of people are poorly understood. Analysis of a festival uncovers collective ...

Jan. 29, 2025 — The universe is getting more disordered, entropy is growing -- this is the second law of thermodynamics. But according to quantum theory, entropy should actually stay the same ...

Kelvin waves have been a mystery for decades but a new method involving superfluid helium-4 can help us control them.

The method is an extension of Weinert’s pseudo-charge method [Weinert M, J Math Phys, 1981, 22:2433–2439] for solving the Poisson equation for the same class of charge density distributions. The ...

Jan. 28, 2025 — A new study explores the effects of both recent and lifetime cannabis use on brain function during cognitive tasks. The study, the largest of its kind ever to be completed ...

Restricted Boltzmann Machine (RBM) is an energy-based, undirected graphical model. It is commonly used for unsupervised and supervised machine learning. Typically, RBM is trained using contrastive ...

The iPhone 11 serves as the de facto successor to the iPhone XR. It scores a 12MP ultra wide-angle camera at the rear which has a focal length of just 13mm and an aperture of F2.4. The iPhone 11 also ...

The Controller Bar and XBOX Game Pass widget make it easier to play. Windows 11 is the most secure version of Windows yet. It's important for security to be invisible so you can focus on using your PC ...

Hence, researchers often simulate the brain as a network of coupled neural masses, each described by a mean-field model. These models capture the essential features of neuronal populations while ...
