Scattering configuration spaces

, 2008
For a compact manifold with boundary $X$ we introduce the $n$-fold scattering stretched product $X^n_{\text{sc}}$ which is a compact manifold with corners for each $n,$ coinciding with the previously known cases for $n=2,3.$ It is constructed by iterated blow up of boundary faces and boundary faces of multi-diagonals in $X^n.$ The resulting space is ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

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.

Directivity enhancement and characteristics of space‐wave, leaky‐wave and creeping‐waves for an impedance cylinder coated with dielectric

IET Microwaves, Antennas & Propagation, 2021
The dielectric‐coated impedance cylinder configuration is investigated thoroughly with respect to the space‐wave, leaky‐wave and creeping‐wave excitations for all source polarizations.

The neural crest‐associated gene ERRFI1 is involved in melanoma progression and resistance toward targeted therapy

Molecular Oncology, EarlyView.
ERRFI1, a neural crest (NC)‐associated gene, was upregulated in melanoma and negatively correlated with the expression of melanocytic differentiation markers and the susceptibility of melanoma cells toward BRAF inhibitors (BRAFi). Knocking down ERRFI1 significantly increased the sensitivity of melanoma cells to BRAFi.

Cis‐regulatory and long noncoding RNA alterations in breast cancer – current insights, biomarker utility, and the critical need for functional validation

Molecular Oncology, EarlyView.
The noncoding region of the genome plays a key role in regulating gene expression, and mutations within these regions are capable of altering it. Researchers have identified multiple functional noncoding mutations associated with increased cancer risk in the genome of breast cancer patients.

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.
