Fusion rings for quantum groups

open access: yes, 2014
We study the fusion rings of tilting modules for a quantum group at a root of unity modulo the tensor ideal of negligible tilting modules. We identify them in type A with the combinatorial rings from [KS] and give a similar description of the sp(2n ...

The gamma -Poincare quantum group from quantum group contraction [PDF]

open access: yesJournal of Physics A: Mathematical and General, 1995
Summary: We propose a contraction of the de Sitter quantum group leading to a Poincaré quantum group in any dimensions. The method relies on the coaction of the de Sitter quantum group on a non-commutative space, and the deformation parameter \(q\) is sent to one.

Colorectal cancer‐derived FGF19 is a metabolically active serum biomarker that exerts enteroendocrine effects on mouse liver

open access: yesMolecular Oncology, EarlyView.
Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

The scientific legacy of Miloslav Havlíček

open access: yesActa Polytechnica
We review the main research achievements of Miloslav Havl´ıˇcek in algebraic methods in Quantum Theory, his extensive work on realisations of Lie algebras and superalgebras and their representation theory, quantum groups and differential equations.

A note on gl2 $$ \mathfrak{g}{\mathfrak{l}}_2 $$-invariant Bethe vectors

open access: yesJournal of High Energy Physics, 2018
We consider gl2 $$ \mathfrak{g}{\mathfrak{l}}_2 $$-invariant quantum integrable models solvable by the algebraic Bethe ansatz. We show that the form of on-shell Bethe vectors is preserved under certain twist transformations of the monodromy matrix.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Dilogarithm Identities for Sine-Gordon and Reduced Sine-Gordon Y-Systems

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2010
We study the family of Y-systems and T-systems associated with the sine-Gordon models and the reduced sine-Gordon models for the parameter of continued fractions with two terms.

Quantum Groups and Quantum Semigroups

open access: yesJournal of Algebra, 1998
For a finite non-empty set \(\mathcal V\), a \(\mathcal V\)-face algebra is an algebra equipped with a coalgebra structure such that the comultiplication is an algebra morphism and the counit satisfies relations involving two complete sets of orthogonal idempotents indexed by \(\mathcal V\) and subject to certain conditions.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

A novel class of translationally invariant spin chains with long-range interactions

open access: yesJournal of High Energy Physics, 2020
We introduce a new class of open, translationally invariant spin chains with long-range interactions depending on both spin permutation and (polarized) spin reversal operators, which includes the Haldane-Shastry chain as a particular degenerate case. The
