Abstract: This note studies the stability problem of nonlinear positive differential-difference equations with unbounded time-varying delays. Under assumptions on the nonlinear vector fields, such as ...

Abstract: In this letter, we propose a differential code shift keying (Diff-CSK) scheme for spectral-efficient and robust underwater acoustic (UWA) communications. In the proposed Diff-CSK, the ...

This project contains Sage-Python code for computing Picard-Fuchs equations by the Griffiths-Dwork method. The current implemented examples are Cox-Katz Examples 5.4.1 and 5.4.2.

Using AI chatbots for even just 10 minutes may have a shockingly negative impact on people’s ability to think and problem-solve, according to a new study from researchers at Carnegie Mellon, MIT, ...
