In an unmagnetized ferromagnetic material, each domain's north pole points in a random direction. Magnetic domains that are oriented in opposite directions cancel one another out, so the material does not produce a net magnetic field. In magnets, on the other hand, most or all the magnetic ...
Chronic constipation and chronic diarrhea can also cause an anal fissure by repeatedly straining the lining of the anus. In the vast majority of cases, an underlying cause is chronic tension in a muscular ring - called the internal anal sphincter - that surrounds the anal canal. ...
Both HCP datasets provided minimally preprocessed data. The preprocessing pipeline has been described in detail elsewhere94. Briefly, this included gradient distortion correction, image distortion correction, registration to participants’ T1w image and to MNI standard space followed by intensity normalisation...
If you're a neuropsychiatrist, for example, a complete map of the brain might be a time-lapse image showing how bipolar disorder unfolds in the brain from birth to the first symptom and what lithium does to stop the process. That might not be enough for you. You might want to know ...

This stroke occurs when an artery that supplies the brain with blood is blocked. The blockage starves the brain of blood and oxygen. If it is very large, the person can fall into a stupor or coma. In people with diabetes, the body does not produce enough of the hormone insulin. ...
How much does an MRI cost? In general, MRIs range in cost from$400 to $3,500. Some of the most common MRI scans include: Head MRI: Scan of the brain and nerve tissues. It is most commonly used to detect and diagnose neurological conditions. ...
MRI machines are large pieces of equipment that are easy to operate. One does not have to manually do anything to the patient apart from asking the patient to lie down. There is no surgical expertise required to produce an MRI machine. MRI technicians are usually not even doctors, and they...
How is a magnetic field produced in an electromagnet? How is the Earth's magnetic field generated? How does Earth's magnetic field resemble a bar magnet? How can a magnetic field produce an electric current? How does an electric current produce a magnetic field?
direct control, with no artificial support at all and the human who does all the work, to the opposite case of no human intervention and the artificial agent that does all the work, a.k.a. an extreme form of supervisory control [21]. The use of such extreme setups is scarce and ...
