Journal of Algebra, 2001 An entwining structure [\textit{T. Brzeziński} and \textit{S. Majid}, Commun. Math. Phys. 191, No. 2, 467-492 (1998; Zbl 0899.55016)] comprises an algebra \(A\), a coalgebra \(C\) and a linear map \(\psi\colon C\otimes A\to A\otimes C\), which is compatible with the multiplication and unit of \(A\), and the comultiplication and counit of \(C ...

Comparative assessment of crystallographic and cryo‐EM models in the Protein Data Bank
FEBS Open Bio, EarlyView.Raw data obtained by X‐ray crystallography or cryo‐EM result in experimental maps, ultimately fitted by atomic models. Although the physical principles are different, the final results can be viewed, compared, and evaluated in the same way. With cryogenic electron microscopy (cryo‐EM) on track to surpass X‐ray crystallography as the preferred method ...

T-Systems and Y-Systems for Quantum Affinizations of Quantum Kac-Moody Algebras
Symmetry, Integrability and Geometry: Methods and Applications, 2009 The T-systems and Y-systems are classes of algebraic relations originally associated with quantum affine algebras and Yangians. Recently the T-systems were generalized to quantum affinizations of a wide class of quantum Kac-Moody algebras by Hernandez ...

Journal of High Energy Physics, 2020 We present a general formula for constructing R-matrices with non-additive spectral parameters associated with a type-I quantum superalgebra. The spectral parameters originate from two one-parameter families of inequivalent finite-dimensional irreducible

IACR Cryptol. ePrint Arch.In quantum cryptography, there could be a new world, Microcrypt, where cryptography is possible but one-way functions (OWFs) do not exist. Although many fundamental primitives and useful applications have been found in Microcrypt, they lack ``OWFs-free'' concrete hardness assumptions on which they are based.

Recent insights into the molecular mechanism of ubiquinol oxidation by cytochrome bc1
FEBS Open Bio, EarlyView.The review reflects on the mechanism of the catalytic reaction in cytochrome bc1: the electron bifurcation that involves the separation of two electrons derived from the quinol oxidation to opposite sides of the enzyme across the membrane. This review summarizes the long‐standing effort to understand the mechanism of quinol oxidation catalyzed by ...

Towards the τ-function of the quantum groups
Physics Letters BThe theory of τ-functions is receiving attention, due to their appearance as non-perturbative partition functions of certain quantum field theories. These τ−functions satisfy Hirota’s bilinear identities (BI).

BMS algebras in 4 and 3 dimensions, their quantum deformations and duals
Journal of High Energy Physics, 2021 BMS symmetry is a symmetry of asymptotically flat spacetimes in vicinity of the null boundary of spacetime and it is expected to play a fundamental role in physics.

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...
