Twist tori and pseudo toric structures

, 2010
Twist tori are examples of exotic monotone lagrangian tori, presented in [1]. This tree of examples grew up over the first one --- the torus $\Theta \in \R^4$, constructured in [2] and [3].

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

A review of the fabrication of twisted two-dimensional material moiré structures

International Journal of Extreme Manufacturing
Stacking two layers of two-dimensional (2D) materials at a twisted angle produces the Moiré structure, which can give rise to novel quantum-correlated states.

Polarization dependent light propagation in $$\textrm{WTe}_2$$ WTe 2 multilayer structure

Scientific Reports, 2023
$$\textrm{WTe}_2$$ WTe 2 is one of the exciting and outstanding semimetallic members of TMDCs, which has attracted immense attention for manipulating light propagation due to its inherent optical anisotropy and hyperbolic characteristic in the infrared ...

Localization Properties of Electronic States in Polaron Model of poly(dG)-poly(dC) and poly(dA)-poly(dT) DNA polymers [PDF]

, 2004
We numerically investigate localization properties of electronic states in a static model of poly(dG)-poly(dC) and poly(dA)-poly(dT) DNA polymers with realistic parameters obtained by quantum-chemical calculation.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

Molecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Impact of Weft Yarn Structure and Fiber Type on Weft Yarn Velocity and Twist Loss in Air-Jet Weaving: A Critical Review

Journal of Natural Fibers
Air-jet weaving is an innovative weaving technique that uses friction between the yarn surface and air stream to propel the weft yarn. The interaction between the yarn surface and air is complex and affects weft yarn motion.

Effect of Different Yarn Combinations on Auxetic Properties of Plied Yarns

AUTEX Research Journal, 2021
This study presents the effects of a novel plied yarn structure consisting of different yarn components and yarn twist levels on the Poisson's ratio and auxetic behavior of yarns.

Twisted EM beams with structured correlations

Optics Letters, 2018
The possibility of restructuring the spectral density of a random light beam up to three times along the propagation path in free space is demonstrated. This can be achieved by prescribing special correlations and different twist factors (by magnitude and/or direction) in the two mutually orthogonal electric field components in the source plane.
