Some common fixed point theorem of rational contractive mappings in dislocated metric spaces
Topological Algebra and its Applications, 2023 We improve the rational contractive condition and prove the common fixed point in the dislocated metric spaces. In addition, the new generalized rational contraction has existence of a common solution for a system of integral equations.

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Jet schemes and minimal toric embedded resolutions of rational double point singularities [PDF]
, 2015 Using the structure of the jet schemes of rational double point singularities, we construct “minimal embedded toric resolutions” of these singularities.

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Sieving rational points on varieties
Transactions of the American Mathematical Society, 2018 An upper bound sieve for rational points on suitable varieties is developed, together with applications to counting rational points in thin sets, to local solubility in families, and to the notion of “friable” rational points with respect to divisors. In the special case of quadrics, sharper estimates are obtained by developing a version of the Selberg

FEBS Letters, EarlyView.The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

On Rational Distance Point Problem for Quadrilaterals
四川大学学报. 自然科学版, 2016 In the present paper, by pointing out some errors in reference [17], we know that the well-known integer distance point problem of Steinhaus is still open. Using the result of Galois extension, we discuss the Steinhaus problem for some quadrilaterals. In

Control of the wave equation at a rational point
, 1992 The wave equation is controlled by a force at one point, which is a rational point of the interval [−1, 1]: geometric interpretations are given of the controllable subclasses.

Homotopy obstructions to rational points [PDF]
, 2013 In this paper we propose to use a relative variant of the notion of the étale homotopy type of an algebraic variety in order to study the existence of rational points on it. In particular, we use an appropriate notion of homotopy fixed points in order to construct obstructions to the local-global principle.
