Warped Schwarzian theory [PDF]

Journal of High Energy Physics, 2020
AbstractWe consider the (twisted) warped Virasoro group Diff(S1)⋉C∞(S1) in the presence of its three cocycles. We compute the Kirillov-Kostant-Souriau symplectic 2-form on coadjoint orbits. We then construct the Euclidean action of the ‘warped Schwarzian theory’ associated to the orbit with SL(2,ℝ)×U(1) stabilizer as the effective theory of the ...

Principal Nested Spheres for Time Warped Functional Data Analysis [PDF]

, 2013
There are often two important types of variation in functional data: the horizontal (or phase) variation and the vertical (or amplitude) variation. These two types of variation have been appropriately separated and modeled through a domain warping method

Multiply Warped Products with Non-Smooth Metrics

, 2002
In this article we study manifolds with $C^{0}$-metrics and properties of Lorentzian multiply warped products. We represent the interior Schwarzschild space-time as a multiply warped product space-time with warping functions and we also investigate the ...

Consideration of the horizontal inertial effects at cantilever beams with nonuniform open sections [PDF]

FME Transactions, 2018
The problem of torsion due to horizontal inertial effects is considered at cantilever beam with variable I-section. Linear variation of height is concerned as most practical one for the design of cantilever beams.

Effective Hamiltonian for surface states of \ce{Bi2Te3} nanocylinders with hexagonal warping

, 2016
The three-dimensional topological insulator \ce{Bi2Te3} differs from other topological insulators in the \ce{Bi2Se3} family in that the effective Hamiltonian of its surface states on a flat semi-infinite slab requires the addition of a cubic momentum ...

Advances in Topological Thermoelectrics: Harnessing Quantum Materials for Energy Applications

Advanced Materials, EarlyView.
Topological materials offer a novel platform for thermoelectric energy conversion through unique band features, including band inversion, linear Dirac bands, surface states, and Berry curvature. These quantum characteristics enable enhanced longitudinal and transverse thermoelectric effects, establishing topological thermoelectrics as a promising ...

Local stability of web of tapered beam subjected to pure bending

Journal of Civil Engineering and Management, 2010
This paper deals with a theoretical and a numerical analysis of local stability of web of tapered beams subjected to a pure bending moment. A standard FEM code COSMOS/M has been used for a numerical estimation of a critical load multiplier.

Warping Parameters Influence on Warp Yarns Properties: Part 1: Warping Speed and Warp Yarn Tension [PDF]

Journal of Textile Science & Engineering, 2013
Warping is aimed at preparing the weaver’s beam to be set up on the weaving machine. In warping, the yarns are taken from the spools placed on the creel and are wound around the warp beam or roll as per the calculated width of the fabric, an uninterrupted length of hundreds of warp yarns results, all oriented parallel to one another.
