Calibrations, Monopoles and Fuzzy Funnels

We present new non-Abelian solitonic configurations in the low energy effective theory describing a collection of N parallel D1--branes. These configurations preserve 1/4, 1/8, 1/16 and 1/32 of the spacetime supersymmetry. They are solutions to a set of generalised Nahm's equations which are related to self-duality equations in eight dimensions. Our solutions represent D1--branes which expand into fuzzy funnel configurations ending on collections of intersecting D3--branes. Supersymmetry dictates that such intersecting D3--branes must lie on a calibrated three-surface of spacetime and we argue that the generalised Nahm's equations encode the data for the construction of magnetic monopoles on the relevant three-surfaces.Comment: 19 pages.

Crossed Aphasia in a Patient with Anaplastic Astrocytoma of the Non-Dominant Hemisphere

Aphasia describes a spectrum of speech impairments due to damage in the language centers of the brain. Insult to the inferior frontal gyrus of the dominant cerebral hemisphere results in Broca\u27s aphasia - the inability to produce fluent speech. The left cerebral hemisphere has historically been considered the dominant side, a characteristic long presumed to be related to a person\u27s handedness . However, recent studies utilizing fMRI have shown that right hemispheric dominance occurs more frequently than previously proposed and despite a person\u27s handedness. Here we present a case of a right-handed patient with Broca\u27s aphasia caused by a right-sided brain tumor. This is significant not only because the occurrence of aphasia in right-handed-individuals with right hemispheric brain damage (so-called crossed aphasia ) is unusual but also because such findings support dissociation between hemispheric linguistic dominance and handedness. © 2017, EduRad.

[Review of] Toshio Morio. Yokohama, California

The reprinting of this book makes accessible to a new generation of readers the pioneering short fiction of the man William Saroyan called the first real Japanese-American writer (Introduction to first edition). First announced by the Caxton Printers for publication in 1942 and finally published in 1949, Yokohama, California suffered a vexed debut and a short life of obscurity and neglect. Given but scant notice by reviewers, Mori\u27s slim collection was received even by his ethnic peers more out of loyal curiosity than any shock of recognition. A unique record of Japanese American life in Northern California in the decades just before World War II, the book became one of the lost volumes of American literature
