On the Strominger system and holomorphic deformations [PDF]
, 2017 We show that the property of existence of solution to the Strominger system in dimension six is neither open nor closed under holomorphic deformations of the complex structure.

On the geometry underlying supersymmetric flux vacua with intermediate SU(2) structure [PDF]
, 2011 We show that supersymmetric flux vacua with intermediate SU(2) structure is closely related to some special classes of half-flat structures. More concretely, solutions of the SUSY equations IIA possess a symplectic half-flat structure, whereas solutions ...

Markets Mitigate Land‐Use Competition From Energy Crops and Increase Farm Revenues
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Meeting the US Sustainable Aviation Fuel Grand Challenge target of 35 billion gal annually by 2050 will require an estimated 380 million–700 million dry tons of agricultural biomass feedstock. This study evaluates the implications of large‐scale biomass production for land use, crop production, and market outcomes under mature market ...
