Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

FEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

DNA ligase LigE increases bacterial transformation with damaged extracellular DNA

FEBS Letters, EarlyView.
The DNA ligase LigE from the naturally competent Gram‐negative bacterium Neisseria gonorrhoaea increases transformation with cut extracellular DNA. This process is ATP‐dependent and relies on the catalytic activity of LigE; it also requires that LigE contains an intact periplasmic localisation sequence, indicating that ligE functions in the periplasm ...

Norm and Numerical Radius Inequalities for a Product of Two Linear Operators in Hilbert Spaces

, 2008
The main aim of the present paper is to establish some norm and numerical radius inequalities for the composite operator BA under suitable assumptions for the transform Cα ,β (T) := (T∗ −α I)(β I−T) , where α ,β ∈ C and T ∈ B(H), of the operators ...

Element-Oriented Construction Methods for Nullnorms on Bounded Lattices

Axioms
Nullnorms are aggregation functions with an annihilator and are generalizations of t-norms and t-conorms. After the introduction of the concept of nullnorms on bounded lattices by Karaçal et al., the studies on their construction methods in such ...

Soft motions encoded by the fold and mediated by conserved hinge sites drive V‐ATPase allosteric machinery and autoinhibition

FEBS Letters, EarlyView.
Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Uniform Description of Calculi for All t-norm Logics

, 2004
A t-norm logic L* is the logic of a standard algebra [0, 1]* = ([0, 1], *, →*, 0), * being a continuous t-norm and →* its residuum. The notion of canonical t-algebra introduced by Haniková [12] and Esteva-Godo-Montagna [9], the sets-as-signs approach to

Fuzzy Data Processing Beyond Min t-Norm [PDF]

, 2016
Usual algorithms for fuzzy data processing -- based on the usual form of Zadeh\u27s extension principle -- implicitly assume that we use the min and -operation (t-norm).

Novel Techniques for Trigonometric Aggregation in Single-Valued Neutrosophic Decision-Making

Vietnam Journal of Computer Science
Aggregation methods for single-valued neutrosophic elements (SVNE) play a critical role in multi-criteria decision-making (MCDM); however, existing approaches often lack the flexibility and representational capacity required to model uncertainty ...
