Last week, I introduced Emmy Noether, an extraordinary figure in the fields of mathematics and physics. To understand Noether ...

For over a century, scientists have thought of time as a fundamental property of the universe. But the more researchers seek ...

The Kalecki-Levy profit equation shows how $1.9 trillion US deficits fuel corporate earnings, creating trade-offs for equity ...

Iterative functional equations form the cornerstone of discrete dynamical systems, capturing the evolution of states under repeated application of a mapping. At their simplest, such equations relate ...

A new national study evaluating a landmark U.S. transplant policy change finds that efforts to correct the harms of race-based kidney function equations are associated with increased kidney ...

Background The relationship of social determinants of health (SDOH), environmental exposures and medical history to lung function trajectories is underexplored. A better understanding of these ...

Abstract: This work is devoted to stochastic functional differential equations with past-dependent random switching, in which the switching process is allowed to take values in a countable state space ...

While building a simpler model for particle interactions, physicists found a new representation involving pi—not a new value ...

Last July, a team of physicians and researchers successfully proposed modifications to the American Medical Association (AMA) Guides to the Evaluation of Permanent Impairment, advocating against the ...
