Decompression sickness is caused by nitrogen bubbles formed in the body of divers and people working with compressed air who leave a compressed environment too fast. The bubbles most commonly afflict the joints, skin, brain, spinal cord, and lungs. Decompression sickness, if untreated, may cause permanent functional damage and is potentially fatal. We report an unusual case of decompression sic...
Diving-related decompression illness is classified into 2 main categories: arterial gas embolism and decompression sickness. The latter is further divided into types 1 and 2, depending on the clinical presentation. MR imaging is currently the most accurate neuroimaging technique available for the detection of brain and spinal cord lesions in neurologic type 2 decompression sickness. Rapid bubbl...
Gene-regulatory complexes often require that pairs of DNA-bound proteins interact by looping-out short (often approximately 100-bp) stretches of DNA. The loops can vary in detailed length and sequence and, thus, in total helical twist, which radically alters their geometry. How this variability is accommodated structurally is not known. Here we show that the inherent twistability of 89- to 105-...
Quantitative Decoding of Interactions in Tunable Nanomagnet Arrays Using First Order Reversal Curves
To develop a full understanding of interactions in nanomagnet arrays is a persistent challenge, critically impacting their technological acceptance. This paper reports the experimental, numerical and analytical investigation of interactions in arrays of Co nanoellipses using the first-order reversal curve (FORC) technique. A mean-field analysis has revealed the physical mechanisms giving rise t...
