Algebroids, heterotic moduli spaces and the Strominger system [PDF]
, 2014 A bstractIn this paper we study compactifications of heterotic string theory on manifolds satisfying the ∂∂¯$$ \partial \overline{\partial} $$-lemma. We consider the Strominger system description of the low energy supergravity to first order in α′ and ...

Advanced Engineering Materials, EarlyView.A hybrid system for de‐icing made of gradient polymer coatings, deposited on aluminum coupled with an electromechanical system, is demonstrated as an effective and durable strategy for reducing drastically ice adhesion. The system is capable of detaching ice blocks over the coating in less than 1 s, regardless of the ice type and covered area ...

Universal moduli spaces of vector bundles and the log-minimal model program on the moduli of curves [PDF]
arXiv, 2014 Recent work on the log minimal model program for the moduli space of curves, as well as past results of Caporaso, Pandharipande, and Simpson motivate an investigation of compactifications of the universal moduli space of slope semi-stable vector bundles over moduli spaces of curves arising in the Hassett-Keel program.

Coulomb branch and the moduli space of instantons [PDF]
, 2014 A bstractThe moduli space of instantons on ℂ2 for any simple gauge group is studied using the Coulomb branch of N=4$$ \mathcal{N}=4 $$ gauge theories in three dimensions. For a given simple group G, the Hilbert series of such an instanton moduli space is

A Novel Simulation Approach for Damage Evolution during Tailored Forming
Advanced Engineering Materials, EarlyView.Traditional damage models are struggling to accurately and efficiently simulate large‐scale three‐dimensional models with a great number of degrees of freedoms. A new gradient‐enhanced damage model based on the extended Hamilton principle can significantly reduce the computation time while ensuring mesh‐independence which is suitable to use in tailored

On the possibility of large axion moduli spaces [PDF]
, 2014 We study the diameters of axion moduli spaces, focusing primarily on type IIB compactifications on Calabi-Yau three-folds. In this case, we derive a stringent bound on the diameter in the large volume region of parameter space for Calabi-Yaus with ...

Mechanisms of De‐icing by Surface Rayleigh and Plate Lamb Acoustic Waves
Advanced Engineering Materials, EarlyView.Ice accretion impacts daily life, renewable energy generation, maintenance, and security in industries and aeronautics. Acoustic waves (AW) are a promising method for ice removal, although de‐icing mechanisms require further investigation to optimize energy efficiency.

GIT and moduli with a twist [PDF]
"Handbook of Moduli" vol. 2, Adv. Lect. Math. 25 (2013), Int.
Press, 259-297, 2011 We survey the role played by GIT in the study of moduli spaces, with an emphasis on the birational geometry of GIT quotients.

Bioinspired Design of Isotropic Lattices with Tunable and Controllable Anisotropy
Advanced Engineering Materials, EarlyView.This study introduces nested isotropic lattices, integrating architectural elements like nesting orders and orientations inspired by bioarchitectures. The design enables tunable anisotropy across nine mono‐nest and twenty multi‐nest lattices with 252 parametric variations, demonstrating transitions from shear‐ to tensile‐compression‐dominant behaviors ...

Jacobi's epsilon and zeta function for moduli outside the interval [0, 1] [PDF]
arXiv, 2015 The formulas that relate Jacobi's Epsilon and Zeta function with real moduli in the interval (1,inf) or with pure imaginary moduli to elliptic functions with moduli in the interval [0,1] are derived.
