Correlation in partially ordered sets

open access: yesDiscrete Applied Mathematics, 1992
Basic results concerning correlation within ordered sets that focus on distributive lattices, systems of subsets ordered by proper inclusion and the family of linear extensions of an arbitrary finite ordered set are reviewed in this paper. Let us quote some interesting results: the Ahlswede-Daykin theorem, the FKG theorem, the universal correlation ...

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

open access: yesFEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

On Superderivations and Jordan Superderivations of Incidence Superalgebras

open access: yesAxioms
In this paper we study superderivations and Jordan superderivations of incidence superalgebras of locally finite Z2-graded posets. We prove that every superderivation can be expressed as a sum of an inner superderivation, an additive superderivation, and

Metastatic niche shaped by host factors influences disseminated cancer cell fate

open access: yesFEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Generation of Permutations of a Partially Ordered Set with Element Dependencies Taken into Account

open access: yesСовременные информационные технологии и IT-образование
This paper is devoted to the development of methods that make it possible to substantially reduce the number of linear orders required for the analysis of partially ordered sets.

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

open access: yesFEBS 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.

Closure operators associated to partially ordered sets

open access: yes, 2009
By applying classical techniques of lattice theory, a closure operator for the relation of causal dependence in partially ordered sets is derived.

Exploring Partially Ordered Multisets: Definitions, Applications, and Combinatorial Parameters

open access: yesUMYU Scientifica Journal
A partially ordered set  is a nonempty set  equipped with a partial order .  Ordered structures are useful for representing application problems that involve comparable and incomparable parameters or inputs.

DNA ligase LigE increases bacterial transformation with damaged extracellular DNA

open access: yesFEBS 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 ...

Upper class of type I on coupled coincidence point results for some contractions in partially ordered JS-metric spaces

open access: yesAdvances in Difference Equations, 2019
In this research work, the necessary and sufficient conditions of a coupled coincidence point of certain type of generalized contractions are explored. These results are considered under JS-metric spaces equipped with a partial order.
