They split the coffee into two regions to examine whether uneven flow does in fact make weaker espresso. One of the regions in the model system hosted more tightly packed coffee than the other, which caused an initial disparity in flow resistance. The extraction of coffee decreased the flow resistance further. Understanding the origin of uneven extraction and avoiding or preventing it could enable better brews and substantial financial savings by using coffee more efficiently.

While the relationship between teacher equity and math identity was evident across races, there was an interesting exception. Black students, in general, had strong math identities, regardless of their teacher's actions. Learning about the factors that affect student math identity is important because a student's attitude towards the subject influences the courses that they take as well as their future career selections. This study suggests that teachers may have a larger role to play in helping students develop a positive math identity than previously recognized.

As aspect ratio and size ratio increase and an aneurysm expands, the stress applied against the aneurysm walls and the time blood spends within it increase. This leads the probability of rupture to rise. Researchers develop a patient-specific mathematical model to examine what aneurysm parameters influence rupture risk prior to surgery. Computed tomography scans are fed into the model, which reconstructs the geometry and blood flow of the aneurysm. It then uses equations to describe the fluid flow, generating information about the blood vessel walls and blood flow patterns.

Their electrical and other physical properties can change --s ometimes quite abruptly, depending on whether the resulting moiré patterns are regularly repeating or non-repeating.
