Multi-Fractality, Universality and Singularity in Turbulence

open access: yesFractal and Fractional, 2022
In most geophysical flows, vortices (or eddies) of all sizes are observed. In 1941, Kolmogorov devised a theory to describe the hierarchical organization of such vortices via a homogeneous self-similar process.

Review of lepton universality tests in B decays [PDF]

open access: yesJournal of Physics G: Nuclear and Particle Physics, 2018
Several measurements of tree- and loop-level b-hadron decays performed in the recent years hint at a possible violation of Lepton Universality. This article presents an experimental and theoretical overview of the current status of the field.

Universality of clonal dynamics poses fundamental limits to identify stem cell self-renewal strategies

open access: yeseLife, 2020
How adult stem cells maintain self-renewing tissues is commonly assessed by analysing clonal data from in vivo cell lineage-tracing assays. To identify strategies of stem cell self-renewal requires that different models of stem cell fate choice predict ...

UNIVERSAL GRAPHS AND UNIVERSAL PERMUTATIONS [PDF]

open access: yesDiscrete Mathematics, Algorithms and Applications, 2013
Let X be a family of graphs and Xn the set of n-vertex graphs in X. A graph U(n) containing all graphs from Xn as induced subgraphs is called n-universal for X. Moreover, we say that U(n) is a propern-universal graph for X if it belongs to X. In the present paper, we construct a proper n-universal graph for the class of split permutation graphs.

News Personalization and Public Service Media: The Audience Perspective in Three European Countries

open access: yesJournalism and Media, 2023
By shining a light on the previously neglected combination of public service media (PSM) and the audience perspective, this paper adds to the debate on (algorithmic) news personalization.

Universal CARs, universal T cells, and universal CAR T cells [PDF]

open access: yesJournal of Hematology & Oncology, 2018
Currently, the two approved T cell products with chimeric antigen receptors (CAR) are from autologous T cells. These CAR T cells approved for clinical use must be generated on a custom-made basis. This case-by-case autologous T cell production platform remains a significant limiting factor for large-scale clinical application due to the costly and ...

Interpreting hints for lepton flavor universality violation [PDF]

open access: yes, 2017
We interpret the recent hints for lepton flavor universality violation in rare $B$ meson decays. Based on a model-independent effective Hamiltonian approach, we determine regions of new physics parameter space that give a good description of the ...
