Modeling System Events and Negative Events Using Thinging Machines Based on Lupascian Logic [PDF]
This paper is an exploration of the ontological foundations of conceptual modeling that addresses the concept of events and related notions. Development models that convey how things change over space and time demand continued attention in systems and software engineering.

Adversarial Attack for Asynchronous Event-based Data [PDF]
Deep neural networks (DNNs) are vulnerable to adversarial examples that are carefully designed to cause the deep learning model to make mistakes. Adversarial examples of 2D images and 3D point clouds have been extensively studied, but studies on event-based data are limited.

First event-by-event fluctuation studies in Pb-Pb collisions at LHC energy by the ALICE experiment [PDF]
The presence of the phase transition can manifest itself by the characteristic behavior of several observables which may vary dramatically from one event to the other. Thus, the study of various conserved quantities on an event-by-event basis offers the possibility to study the phase transition and the nature of high density matter.
