Huerta al alba

John Huerta - Research Statement

My research is an investigation into the mathematical foundations of supersymmetry, especially the theories of superstrings and supergravity. Over the past 30 years, string theory and related ideas have proven to be connected to many beautiful notions in differential geometry, such as mirror symmetry [Kontsevich] and gerbes [Brylinski, Freed and Witten]. The overarching goal of my work is to ex...

Pityriasis alba with poliosis.

Pityriasis alba is a skin disease, commonly seen in children and young adults. This case presents the ocular association of this disease in a 10 years old Pakistani male. Ocular features in this case were poliosis, tilted disc, high myopia and chorioretinal degeneration. Tilted discs and high myopia can be coincidental but poliosis and decreased pigment in retinal pigment epithelium are closely...

The importance of cross-validation, accuracy, and precision for measuring plumage color: A comment on Vaquero-Alba et al. (2016)

Vaquero-Alba and colleagues published a study in The Auk: Ornithological Advances comparing objective color measurements of plumage taken in the field directly on a bird’s body to those taken in the lab on collected feathers arranged to emulate the appearance of a bird’s natural plumage. Although the field measures of plumage color were less repeatable than lab measures, the authors concluded t...

Quercus nigra and Quercus alba

lnvestigaltons into the nature of desiccation-sensitive, or recalcitant, seed behavior have as yet failed to identify exact causes of this phenomenon. Experiments with Quercus nigra L. and Quercus alba L. were conducted to examine physiological and biochemical changes brought about by seed desiccation and to determine if there were predictable changes in seed moisture content, m enthalpy (heat ...
