There is an increasing interest in the development of new data-driven models
useful to assess the performance of communication networks. For many
applications, like network monitoring and troubleshooting, a data model is of
little use if it...

Let (gn​)n≥1​ be a sequence of independent and identically
distributed (i.i.d.) d×d real random matrices. Set Gn​=gn​gn−1​…g1​ and Xnx​=Gn​x/∣Gn​x∣, n≥1, where ∣⋅∣ is an
arbitrary norm in $...
Quantum holonomic link invariants derived from stated skein algebras

We define invariants for a framed link equipped with a SL2 local system in
its complement and additional combinatorial data based on the theory of
representations of stated skein algebras at roots of unity of punctured bigons
and the geomet...

Spectra emitted from ionized nebulae typically contain collisionally excited
and recombination lines, which can be used to trace physical conditions and
chemical abundances of the interstellar medium in our Galaxy and other
galaxies. "AtomN...

Automatic prostate segmentation in transrectal ultrasound (TRUS) images is of
essential importance for image-guided prostate interventions and treatment
planning. However, developing such automatic solutions remains very challenging
due to ...
A robust graph-based approach to observational equivalence

We propose a new step-wise approach to proving observational equivalence, and
in particular reasoning about fragility of observational equivalence. Our
approach is based on what we call local reasoning. The local reasoning exploits

GABAergic interneurons can be subdivided into three subclasses: parvalbumin
positive (PV), somatostatin positive (SOM) and serotonin positive neurons. With
principal cells (PCs) they form complex networks. We examine PCs and PV
responses in...

Clustering, or unsupervised classification, is a task often plagued by
outliers. Yet there is a paucity of work on handling outliers in clustering.
Outlier identification algorithms tend to fall into three broad categories:

Although the free energy of a genome packing into a virus is dominated by
DNA-DNA interactions, ordering of the DNA inside the capsid is
elasticity-driven, suggesting general solutions with DNA organized into
spool-like domains. Using analy...
