Weak ∗-Orderings on ∗-Fields

open access: yesJournal of Algebra, 1993
Let \(D\) be a division ring with center \(F\) and an involution \(*\). In this paper the author studies a special class of Baer-orderings, so called weak \(*\)-orderings, on \(D\). One motivation for this is the fact that \(*\)- fields which are finite dimensional over their centers only admit \(*\)- orderings if they are trivial.

A Higher-Order Calculus of Computational Fields [PDF]

open access: yesACM Transactions on Computational Logic, 2019
The complexity of large-scale distributed systems, particularly when deployed in physical space, calls for new mechanisms to address composability and reusability of collective adaptive behaviour. Computational fields have been proposed as an effective abstraction to fill the gap between the macro-level of such systems (specifying a system’s collective

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Phosphoinositides and inositol phosphates as molecular glues

open access: yesFEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

On the bosonic origin of the elastic constants of the solids

open access: yesResults in Physics
It is shown that the elastic compliances, sij, are defined, as the elastic stiffness constants, cij, by bosons. The constants cij are well-known to be given by the velocities of the sound waves, called here Debye-bosons. Sound waves are evidently elastic

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Relating interleaving and Fréchet distances via ordered merge trees

open access: yesJournal of Computational Geometry
Merge trees are a common topological descriptor for data with a hierarchical component, such as terrains and scalar fields. The interleaving distance, in turn, is a common distance for comparing merge trees.

Isothermal section of the La2O3-Lu2O33-Er2O3 ternary phase diagram at 1250°С

open access: yesChemistry Journal of Moldova: General, Industrial and Ecological Chemistry, 2023
The phase equilibria in the ternary La2О3–Lu2O3–Er2O3 system at 1250°C were studied by X-ray diffraction, and electron microscopy in the overall concentration range.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS 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
