Graphene Bilayer with a Twist: Electronic Structure [PDF]
Physical Review Letters, 2007 Electronic properties of bilayer and multilayer graphene have generally been interpreted in terms of AB or Bernal stacking. However, it is known that many types of stacking defects can occur in natural and synthetic graphite; rotation of the top layer is often seen in scanning tunneling microscopy (STM) studies of graphite.

Modeling Helical Structures in Relativistic Jets
, 2003 Many jets exhibit twisted helical structures. Where superluminal motions are detected, jet orientation and pattern/flow speed are considerably constrained. In this case modeling efforts can place strong limits on conditions in the jet and in the external

TWIST-3 EFFECTS IN POLARIZED PHOTON STRUCTURE [PDF]
International Journal of Modern Physics A, 2003 The polarized photon structure is described by two spin structure functions [Formula: see text] and [Formula: see text] which can be studied in the future polarized ep or e+e- colliders. Here we investigate the QCD twist-3 effects in [Formula: see text] to the leading order in QCD.

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.

Theory of self-assembled smectic-A "crenellated disks"
, 2013 Smectic-A monolayers self-assembled in aqueous solutions of chiral fd viruses and a polymer depletant have been shown to exhibit a variety of structures including large, flat disks and twisted ribbons.

Twisted bi-symplectic structure on Koszul twisted Calabi-Yau algebras
Selecta Mathematica, 2022 For a Koszul Artin-Schelter regular algebra (also called twisted Calabi-Yau algebra), we show that it has a "twisted" bi-symplectic structure, which may be viewed as a noncommutative and twisted analogue of the shifted symplectic structure introduced by Pantev, To n, Vaqui and Vezzosi.

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 ...
