Assessment of the application "twist-off" method for determining the in situ compressive and flexural strengths in the fiber concrete [PDF]
Journal of Structural and Construction Engineering, 2021 Since the batching, transportation, pouring, compaction and curing of the specimens used in laboratory testing of concrete, either from these employed in real structures, the in-situ methods are needed for assessing the quality of existing concrete in ...

Twisted cohomotopy implies twisted string structure on M5-branes [PDF]
Journal of Mathematical Physics, 2021 We show that charge-quantization of the M-theory C-field in J-twisted Cohomotopy implies the emergence of a higher Sp(1)-gauge field on single heterotic M5-branes, which exhibits a worldvolume Stringc2-structure.

Investigation on the effect of cotton-tencel (50:50) siro yarn twist multipliers on fabric stiffness
Heliyon, 2022 The properties of fabrics are mainly affected by constituent fiber properties and yarn structures. The yarn structures are primarily dependent on the spinning technique.

Explicit formulae for Chern-Simons invariants of the hyperbolic J(2n,-2m) knot orbifolds
Pracì Mìžnarodnogo Geometričnogo Centru, 2023 We calculate the Chern-Simons invariants of the hyperbolic double twist knot orbifolds using the Schläfli formula for the generalized Chern-Simons function on the family of cone-manifold structures of double twist knots.

Spinorially Twisted Spin Structures, III: CR Structures [PDF]
The Journal of Geometric Analysis, 2017 We develop a spinorial description of CR structures of arbitrary codimension. More precisely, we characterize almost CR structures of arbitrary codimension on (Riemannian) manifolds by the existence of a Spin$^{c, r}$ structure carrying a partially pure spinor field.

Twist Automorphisms and Poisson Structures
Symmetry, Integrability and Geometry: Methods and Applications, 2023 We introduce (quantum) twist automorphisms for upper cluster algebras and cluster Poisson algebras with coefficients. Our constructions generalize the twist automorphisms for quantum unipotent cells. We study their existence and their compatibility with Poisson structures and quantization.

Twist - 3 polarized structure functions [PDF]
Nuclear Physics B - Proceedings Supplements, 2000 We review the nucleon's twist-3 polarized structure functions from the viewpoint of gauge invariant, nonlocal light-cone operators in QCD. We discuss a systematic treatment of the polarized structure functions and the corresponding parton distribution functions.

Applied Sciences, 2020 A mode-matching formulation is presented and used to analyze the dispersion properties of twist-symmetric transmission lines. The structures are coaxial lines periodically loaded with infinitely thin screens, which are rotated with respect to each other ...

Elastic–Plastic Material Deformation and Conveying Value of Twist-Free Turned Surfaces
Surfaces, 2022 Counter-surfaces for radial shaft seals are usually finished by infeed grinding to avoid macro twist structures on the surface since they can impose a conveying action on the lubricant.
