We show that magnetic monopoles appear naturally in granular quantum matter. Their condensation leads to a new state of matter, superinsulation, which Cooper pairs are bound into purely electric pions by strings flux. These flux tubes, the dual Abrikosov vortices, prevent separation charge–hole pairs, thereby causing an infinite resistance, even at finite temperatures, behaviour superconductors...

leukodystrophies are familial disorders with onset usually in infancy or childhood. the name comes from the greek leuko meaning white and dystrophy meaning imperfect growth or development. leukodystrophy is a progressive, genetic disorder with an autosomal recessive or x-linked mode of inheritance. the clinical features consist of motor dysfunction with varying degrees of cognitive decline. mag...

We show that the magnetic component of the photon field produced by dark matter axions via the two-photon coupling mechanism in a Sikivie haloscope is an important parameter passed over in previous analysis and experiments. The interaction of the produced photons will be resonantly enhanced as long as they couple to the electric or magnetic mode structure of the haloscope cavity. For typical ha...

BACKGROUND Magnetic resonance imaging studies have reported that lithium can increase the volume of gray matter in the human brain, a finding that has been ascribed to the established neurotrophic or neuroprotective effects of the drug. Lithium, however, might directly influence the intensity of the magnetic resonance signal so it is possible that the volumetric findings are artifactual, essent...

The use of magnetic resonance imaging (MRI) has resulted in the detection of an increasing number of children with an apparently leukodystrophic white matter. Laboratory tests and the clinical presentation, however, often do not correspond to any known entity and the course is sometimes not progressively deteriorating. Such children with white-matter changes and no known diagnosis were the subj...

We provide a new tool to interpret the large scale structure of the Universe. As suggested in Paper II, energy density filaments could have been produced by subjacent magnetic flux tubes when the Universe was dominated by radiation. In more recent time epochs, small scale filaments have evolved in a complicated way, but large scale filaments have probably survived and should be identified with ...

Gravitational, magnetic and superfluid forces can stress the crust of an evolving neutron star. Fracture of the crust under these stresses could affect the star’s spin evolution and generate high-energy emission. We study the growth of strain in the crust of a spinning down, magnetized neutron star and examine the initiation of crust cracking (a starquake). In preliminary work (Link, Franco & E...

PURPOSE This study was aimed to experimentally and numerically investigate the feasibility of measuring cerebral white matter perfusion using pseudocontinuous arterial spin labeling (PCASL) 3T magnetic resonance imaging (MRI) at a relatively fine resolution to mitigate partial volume effect from gray matter. MATERIALS AND METHODS The Institutional Research Ethics Committee approved this study...

INTRODUCTION Alexander disease is a rare disorder resulting from a glial fibrillary acidic protein gene mutation which causes progressive degeneration of white matter. With the usual poor prognosis, there are few case reports with long-term follow-up. We report the five-year clinical course of Alexander disease in one case using serial magnetic resonance imaging. CASE PRESENTATION A 12-month-...
