Let be a locally convex space and nonempty closed convex sets. If either or is locally compact and (where gives the recession cone) is a linear subspace, then is closed. |
https://en.wikipedia.org/wiki/Strike%20tone | The strike tone, strike note, or tap note, of a percussion instrument (e.g. bell, chime or gong) when struck, is the dominant note perceived immediately by the human ear. It is also known as the prime or fundamental note. However, an analysis of the bell's frequency spectrum reveals that the fundamental only exists wea... |
https://en.wikipedia.org/wiki/X-inactivation | X-inactivation (also called Lyonization, after English geneticist Mary Lyon) is a process by which one of the copies of the X chromosome is inactivated in therian female mammals. The inactive X chromosome is silenced by being packaged into a transcriptionally inactive structure called heterochromatin. As nearly all fem... |
https://en.wikipedia.org/wiki/10G-PON | 10G-PON (also known as XG-PON or G.987) is a 2010 computer networking standard for data links, capable of delivering shared Internet access rates up to 10 Gbit/s (gigabits per second) over existing dark fiber. This is the ITU-T's next generation standard following on from GPON or Gigabit-capable PON. Optical fibre is s... |
https://en.wikipedia.org/wiki/International%20Plant%20Names%20Index | The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes."

https://en.wikipedia.org/wiki/Energy%20cannibalism | Energy cannibalism refers to an effect where rapid growth of a specific energy producing industry creates a need for energy that uses (or cannibalizes) the energy of existing power plants. Thus during rapid growth the industry as a whole produces no new energy because it is used to fuel the embodied energy of future po... |
https://en.wikipedia.org/wiki/Collimated%20beam | A collimated beam of light or other electromagnetic radiation has parallel rays, and therefore will spread minimally as it propagates. A perfectly collimated light beam, with no divergence, would not disperse with distance. However, diffraction prevents the creation of any such beam.
Light can be approximately collima... |
