In purchasing power parity (PPP) terms, India is now the world’s third largest economy — surpassing Japan.
By Ankit Panda
In a sliver of good economic news during an Indian election that is widely focused on economic growth, the World Bank announced in a report on Tuesday that India overtook Japan as the world’s third largest economy in terms of purchasing power parity (PPP). According to the World Bank’s International Comparison Program (ICP) data, India holds a 6.4 percent share of global GDP on a PPP basis. The United States remains in first place with a 17.1 percent share and China trails it at 14.9 percent. Japan, while still the world’s third largest economy in nominal terms, holds a 4.8 percent share of global wealth.

KARACHI: A Pakistani scholar has devised a non-invasive way to sense brain pressure which could significantly change the current paradigm of neurological care of those suffering from brain injury or disease.
Monitoring intracranial pressure (ICP) is the most important thing to assess brain injury, hemorrhage (internal blood flow), tumors and other neurological problems. But current methods to measure this pressure are highly invasive – requiring a neurosurgeon to drill a hole in the skull to place a pressure sensor or catheter inside the brain – and are thus restricted to the very severe cases.
Pakistani scientist, Faisal Kashif has devised a non-invasive technology for ICP monitoring in his PhD thesis at the Massachusetts Institute of Technology, US. The method is based on processing available clinical signals using a mathematical model of relevant physiology. It provides real time estimates of ICP and cerebrovascular impedance, the latter is an indicator of brain’s ability to maintain its blood supply.
“ICP is a key neurological vital sign and is affected in several brain pathologies – even in concussions and migranes – and this non-invasive method could help in monitoring a vastly larger pool of patients,” said Kashif. He further added that unlike the invasive approaches which require a neurosurgical facility, the non-invasive method can also be applied in emergency-care settings where most trauma patients are first brought. Having access to ICP in a timely manner can guide doctors to provide life-saving interventions. …
