Abstract: The source coding problem with encoded side information is considered. A lower bound on the strong converse exponent has been derived by Oohama, but its tightness has not been clarified. In ...

The numerical integration of stiff equations is a challenging problem that needs to be approached by specialized numerical methods. Exponential integrators form a popular class of such methods since ...

This Olympiad-style exponential problem looks simple at first — until you try solving it. Test your skills and see if you can crack it before I walk through the clever solution step-by-step. Trump ...

NEW YORK and HOUSTON, Nov. 7, 2025 /PRNewswire/ -- A mismatch between two common tests for kidney function may indicate a higher risk for kidney failure, heart disease, and death, a new study shows.

The Riemann hypothesis is the most important open question in number theory—if not all of mathematics. It has occupied experts for more than 160 years. And the problem appeared both in mathematician ...

This paper investigates a class of coupled neural networks with delays and ad-dresses the exponential synchronization problem using delay-compensatory impulsive control. Razumikhin-type inequalities ...

The thyroid makes hormones that influence various organs and systems within the body, including the systems responsible for a person’s sex drive, or “libido.” Reduced libido can arise as a result of ...

In this work the matrix exponential function is solved analytically for the special orthogonal groups up to . The number of occurring k-th matrix powers gets limited to by exploiting the ...
