A Variational Formulation of Symplectic Noncommutative Mechanics

, 2007
The standard lore in noncommutative physics is the use of first order variational description of a dynamical system to probe the space noncommutativity and its consequences in the dynamics in phase space.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Capturing the dynamic target by the robot manipulator in high-dimensional configuration space map

International Journal of Advanced Robotic Systems, 2020
In robotics, the tough problem about the dynamic target capturing consists of tracking the target by the robot manipulator and grasping the target by the robot finger.

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Generation of program trajectories for robotic manipulators of point contact welding in the workspace with obstacles

Доклады Белорусского государственного университета информатики и радиоэлектроники, 2019
New effective algorithms for generating paths of robotic manipulators for point-contact welding were proposed. They are based on the statistical model of the configuration space.

Spatial configuration Based on Relationship between Buildings and Road Network in Kupang City, East Nusa Tenggara Province, Indonesia

ARTEKS : Jurnal Teknik Arsitektur
Oebobo District has the highest density level among all sub-districts in Kupang City. The impact of population growth and circulation is that the mobility of people and goods often occurs quickly, thus hampering efficient observation.

A configuration space for equivariant connective K-homology

, 2015
Following ideas of Graeme Segal, we construct an equivariant con- figuration space that is a model of equivariant connective K-homology spec- trum for finite groups, as a consequence we obtain an induction structure for equivariant connective K-homology.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...
