The Effect of Decomposition Rule Modeling on the Efficiency of Hierarchical Planners

open access: yesProceedings of the International Florida Artificial Intelligence Research Society Conference
Hierarchical planning is a widely used approach in automated planning that breaks down complex tasks into manageable subtasks, facilitating more efficient problem-solving.

Normal Forms of the Degenerate Differential Autonomous and Non Autonomous Equations with the Maximal Jordan Chain of Length Two and Three

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2015
Standard methods of normal form construction are adapted for degenerate differential equations in the case of the existence of maximal length Jordan chain. For n=2 and 3 examples are considered.

Normal forms of piecewise-smooth monodromic systems

open access: yesAdvances in Nonlinear Analysis
Normal form is an important tool in the study of bifurcations but, unlike those for smooth differential systems, normal forms for piecewise-smooth systems have difficulty with the near-identity transformation, which is constructed piecewise but needs to ...

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Transformation of Grammars into Normal Forms

open access: yes, 2012
This thesis deals with issues of normal forms from theory of formal languages. Basic terms from this area are listed here, different types of grammars as well and especially normal forms and algorithms that transfer grammars into normal forms ...

Spiking Neural P Systems: Stronger Normal Forms [PDF]

open access: yes, 2007
Spiking neural P systems are computing devices recently introduced as a bridge between spiking neural nets and membrane computing. Thanks to the rapid research in this eld there exists already a series of both theoretical and application studies.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

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.
