Gluing and deformations of asymptotically cylindrical special Lagrangians [PDF]

open access: yesarXiv, 2017
We study gluings of asymptotically cylindrical special Lagrangian submanifolds in asymptotically cylindrical Calabi--Yau manifolds. We prove both that there is a well-defined gluing map, and, after reviewing the deformation theory for special Lagrangians, prove that this gluing map defines a local diffeomorphism from matching pairs of deformations of ...

Growing climatic sensitivity of U.S. agriculture linked to technological change and regional specialization

open access: yesScience Advances, 2018
Core U.S. agricultural region has become more sensitive to climatic shocks due to changes in technology and specialization. A pressing question for climate change adaptation is whether ongoing transformations of the agricultural sector affect its ability

Very special divisors on 4-gonal real algebraic curves [PDF]

open access: yesarXiv, 2013
Given a real curve, we study special linear systems called "very special" for which the dimension does not satisfy a Clifford type inequality. We classify all these very special linear systems when the gonality of the curve is small.

A direct demonstration of functional specialization in human visual cortex

open access: yesJournal of Neuroscience, 1991
We have used positron emission tomography (PET), which measures regional cerebral blood flow (rCBF), to demonstrate directly the specialization of function in the normal human visual cortex.

Special Numbers, Special Quaternions and Special Symbol Elements [PDF]

open access: yes, 2018
{\small In this paper we define and we study properties of} $\left(l,1,p+2q,q\cdot l\right) -$ {\small numbers,} $\left(l,1,p+2q,q\cdot l\right) -$ {\small quaternions,} $\left(l,1,p+2q,q\cdot l\right) -$ {\small symbol elements. Finally, we obtain an algebraic structure with these elements.}

Galilean relativity, special relativity and the work-kinetic energy theorem revisited [PDF]

open access: yesarXiv, 2007
Transformation equations for the kinetic energy of the same bullet in Galileo's and Einstein's special relativity are derived. The special relativity result is extended to the case of a photon.
