Phantoms in the brain
After amputation many people experience vivid sensations of the body part they have lost. These “sensory ghosts” can arise within hours of the loss of the limb and are often painful. Such phenomena have been a mysterious part of medical lore for over a century, but recent research suggests that phantoms can teach us substantial lessons about the organisation and plasticity of the brain. We stan...
متن کاملPhantoms of the brain.
8 Theorists calculate that this drastic change in the structure of matter sets in over a narrow range of temperatures centred around 10 12 K. To gauge the change, it is instructive to compare the degrees of freedom — the number of different particles that energy can go to. On the hadronic side of the transition, the important particles at these temperatures are just the pions (the other hadrons...
متن کاملAn Investigation of Calibration Phantoms for CT Scanners with Tube Voltage Modulation
The effects of calibration phantoms on the correction results of the empirical artifacts correction method (ECCU) for the case of tube modulation were investigated. To improve the validity of the ECCU method, the effect of the geometry parameter of a typical single-material calibration phantom (water calibration phantom) on the ECCU algorithm was investigated. Dual-material calibration phantoms...

15 صفحه اولAnalyzing the Behavior of Hybrid Steel System of Tube in Tube with Bracing and Belt Truss
Nowadays, due to the escalation in construction of high-rise structures, the need for selecting a proper resistant structural system against earthquake and wind has increased significantly. These systems should show an optimized use of materials and should be presented as a hard and efficient structure. A good example of a high efficient system in high-rise buildings can be indicated is, the tu...
