A research team at Kumamoto University (Japan) has unveiled a new mathematical framework that makes it possible to accurately model systems using multiple sensors that operate at different sensing ...

Sufficient conditions are given for the existence, uniqueness and finite-dimensional approximation of the solution to a first-order infinite-dimensional vector differential equation. Given a suitable ...

Abstract: Motivated by a renewed interest in cis-lunar space vehicle operations and other Lunar missions, we consider how to make judicious use of the invariant manifolds associated with the periodic ...

Objective We examined the association between job stress and leisure-time physical inactivity, adjusting for individual time-invariant attributes. Methods We used data from a Japanese occupational ...

Two weeks ago, a modest-looking paper was uploaded to the arXiv preprint server with the unassuming title “On the invariant subspace problem in Hilbert spaces”. The paper is just 13 pages long and its ...
