Symmetries in Natural Language Syntax and Semantics: The Lambek-Grishin Calculus
In this paper, we explore the Lambek-Grishin calculus LG: a symmetric version of categorial grammar based on the generalizations of Lambek calculus studied in Grishin [1]. The voca...

Approximately bisimilar symbolic models for nonlinear control systems
Control systems are usually modeled by differential equations describing how physical phenomena can be influenced by certain control parameters or inputs. Although these models ar...

Analysing Periodic Phenomena by Circular PCA
Experimental time courses often reveal a nonlinear behaviour. Analysing these nonlinearities is even more challenging when the observed phenomenon is cyclic or oscillatory. This me...

Scales in Natural Images and a Consequence on their Bounded Variation Norm
This paper introduces a new method for analyzing scaling phenomena in natural images, and draws some consequences as to whether natural images belong to the space of functions with...

Optimistic Parallel Discrete Event Simulations of Physical Systems Using Reverse Computation
Efficient computer simulation of complex physical phenomena has long been challenging due to their multiphysics and multi-scale nature. In contrast to traditional time-stepped exe...
