Northwestern was elected to the Association of American Universities in 1917 and remains a research university with "very high" research activity. Northwestern's schools of management, engineering, and communication are among the most academically productive in the nation. Northwestern received $550 million in research funding in 2014. Northwestern supports nearly 1,500 research laboratories across two campuses, predominately in the medical and biological sciences. Through the Innovation and New Ventures Office (INVO), Northwestern researchers disclosed 247 inventions, filed 270 patents applications, received 81 foreign and US patents, started 12 companies, and generated $79.8 million in licensing revenue in 2013. The bulk of revenue has come from a patent on pregabalin, a synthesized organic molecule discovered by chemistry professor Richard Silverman, which ultimately was marketed as Lyrica, a drug sold by Pfizer, to combat epilepsy, neuropathic pain, and fibromyalgia. INVO has been involved in creating a number of centers, including the Center for Developmental Therapeutics (CDT) and the Center for Device Development (CD2). It has also helped form over 50 Northwestern startup companies based on Northwestern technologies.
How many companies were started through Southwestern's Innovations and New Ventures Office?

Lasers emitting in the green part of the spectrum are widely available to the general public in a wide range of output powers. Green laser pointers outputting at 532 nm (563.5 THz) are relatively inexpensive compared to other wavelengths of the same power, and are very popular due to their good beam quality and very high apparent brightness. The most common green lasers use diode pumped solid state (DPSS) technology to create the green light. An infrared laser diode at 808 nm is used to pump a crystal of neodymium-doped yttrium vanadium oxide (Nd:YVO4) or neodymium-doped yttrium aluminium garnet (Nd:YAG) and induces it to emit 281.76 THz (1064 nm). This deeper infrared light is then passed through another crystal containing potassium, titanium and phosphorus (KTP), whose non-linear properties generate light at a frequency that is twice that of the incident beam (563.5 THz); in this case corresponding to the wavelength of 532 nm ("green"). Other green wavelengths are also available using DPSS technology ranging from 501 nm to 543 nm. Green wavelengths are also available from gas lasers, including the helium–neon laser (543 nm), the Argon-ion laser (514 nm) and the Krypton-ion laser (521 nm and 531 nm), as well as liquid dye lasers. Green lasers have a wide variety of applications, including pointing, illumination, surgery, laser light shows, spectroscopy, interferometry, fluorescence, holography, machine vision, non-lethal weapons and bird control.
What is the range of green wavelengths available when using DPSS technology?
A: 501 nm to 543 nm

The role and functions of the CIA are roughly equivalent to those of the United Kingdom's Secret Intelligence Service (the SIS or MI6), the Australian Secret Intelligence Service (ASIS), the Egyptian General Intelligence Service, the Russian Foreign Intelligence Service (Sluzhba Vneshney Razvedki) (SVR), the Indian Research and Analysis Wing (RAW), the Pakistani Inter-Services Intelligence (ISI), the French foreign intelligence service Direction Générale de la Sécurité Extérieure (DGSE) and Israel's Mossad. While the preceding agencies both collect and analyze information, some like the U.S. State Department's Bureau of Intelligence and Research are purely analytical agencies.[citation needed]
What does ASIS stand for?
A: Australian Secret Intelligence Service

In the tree a knot is either the base of a side branch or a dormant bud. A knot (when the base of a side branch) is conical in shape (hence the roughly circular cross-section) with the inner tip at the point in stem diameter at which the plant's vascular cambium was located when the branch formed as a bud.
What measurement of a stem determines a knot's inner tip placement?
A:
diameter
