Semisimplicity of the quantum cohomology for smooth Fano toric varieties associated with facet symmetric polytopes [PDF]

open access: yes, 2012
The degree zero part of the quantum cohomology algebra of a smooth Fano toric symplectic manifold is determined by the superpotential function, W, of its moment polytope. In particular, this algebra is semisimple, i.e.

Lateral distortional buckling of cellular composite-beams

open access: yesRevista IBRACON de Estruturas e Materiais, 2018
In the region of negative bending moments of continuous and semi-continuous steel and concrete composite beams, the inferior portion of the steel section is subjected to compression while the top flange is restricted by the slab, which may cause a global

The Present Moment as a Critical Moment

open access: yesNegotiation Journal, 2004
Abstract Like a musical interlude, the present moment hovers between becoming the past and progressing into the future. Critical moments, for the author, are moments in which the parties are fully in the present or the “now,” caught in a pivotal space where any action, or even inaction, will change the destiny of the situation and the ...

Investigation of Chirality Effect on Axial and Torsional Buckling Behavior of SWCNTs Using Finite Element Method [PDF]

open access: yesمجله مدل سازی در مهندسی, 2017
In this paper, chirality effect on the buckling behavior of SWCNTs has been investigated. In order to explore the effect of chiral angle, all structures are used with the same length and diameter but different chiral angles.

On refined volatility smile expansion in the Heston model [PDF]

open access: yes, 2010
It is known that Heston's stochastic volatility model exhibits moment explosion, and that the critical moment $s_+$ can be obtained by solving (numerically) a simple equation.

Spin-boson coupling in continuous-time quantum Monte Carlo

open access: yes, 2013
A vector bosonic field coupled to the electronic spin is treated by means of the continuous-time quantum Monte Carlo method. In the Bose Kondo model with a sub-Ohmic density of states $\rho_{B}(\omega) \propto \omega^{s}$ with s=0.2, two contributions to

Assessment of the OTEC cold water pipe design under bending loading: A benchmarking and parametric study using finite element approach

open access: yesJournal of the Mechanical Behavior of Materials, 2023
Ocean thermal energy conversion (OTEC) is a floating platform that generates electricity from seawater heat. The cold water pipe (CWP) used in OTEC has a length of 1,000 m and a diameter of 10 m, making it susceptible to bending loads from ocean currents.
