Sparśa
Sparśa (Sanskrit; Pali: phassa) is a Sanskrit/Indian term that is translated as "contact", "touching", "sensation", "sense impression", etc. It is defined as the coming together of three factors: the sense organ, the sense object, and sense consciousness (vijnana). For example, contact (sparsha) is said to occur at the coming together of the eye organ, a visual object, and the visual sense consciousness. Sparśa is identified within the Buddhist teachings as:

Equinox (Celestial Coordinates)
In astronomy, an equinox is either of two places on the celestial sphere at which the ecliptic intersects the celestial equator. Although there are two intersections of the ecliptic with the celestial equator, by convention, the equinox associated with the Sun's ascending node is used as the origin of celestial coordinate systems and referred to simply as "the equinox". In contrast to the common usage of spring/vernal and autumnal equinoxes, the celestial coordinate system equinox is a direction in space rather than a moment in time. In a cycle of about 25,800 years, the equinox moves westward with respect to the celestial sphere because of perturbing forces; therefore, in order to define a coordinate system, it is necessary to specify the date for which the equinox is chosen. This date should not be confused with the epoch. Astronomical objects show real movements such as orbital and proper motions, and the epoch defines the date for which the position of an object applies. Therefore, a complete specification of the coordinates for an astronomical object requires both the date of the equinox and of the epoch. The currently used standard equinox and epoch is J2000.0, which is January 1, 2000 at 12:00 TT. The prefix "J" indicates that it is a Julian epoch. The previous standard equinox and epoch was B1950.0, with the prefix "B" indicating it was a Besselian epoch. Before 1984 Besselian equinoxes and epochs were used. Since that time Julian equinoxes and epochs have been used.

Eye Injuries in the 2019–2020 Chilean Protests
The 2019–2020 Chilean protests are characterised by widespread eye injuries, including many globe ruptures ("exploded eyes"), among protesters as result of Chilean riot police's use of "rubber" bullets and tear gas grenades. Data from the National Institute of Human Rights (INDH) shows that the use of "rubber" bullets and pellets by security forces has left at least 1863 injured, including 268 with eye problems. According to the Chilean Ophthalmology Society, this is the highest number of injuries of this type registered during protests or in conflict zones in the world. In late November, security forces announced the suspension of the use of "rubber" pellets as a crowd control method in the protests. The INDH updated figures at the end of January 2020 reporting that 427 persons had received eye injuries at the hands of the police. Almost 90% of the injured are men. As of early January 2020 the age of injured goes from 14 to 59 years, and averages 28 years. UTO, the Ocular Trauma Unit (Spanish: Unidad de Trauma Ocular) of Hospital del Salvador has treated the majority of eye injuries. By November 18 it was estimated that nearly 30% of the cases of eye injury that had occurred in the context of the protests involved "exploded eyes", a trauma for which there is no remedy, and results in complete blindness of the affected eye. Monday October 21 is reported by ophthalmologist Mauricio López as one of the days with most eye injuries, that day Hospital Salvador received twenty cases of which ten alone came in the span of a single hour. The high command of the Chilean police ordered an end to the use of supersock cartridges on October 31. Despite this and other initiatives declared by the high command the number of severe eye injuries in November was about the double as in October. As result of the COVID-19 pandemic in Chile many of the injured have not been able to continue their treatments. In the cases where injured have gone to hospital for treatment and supervision some have had to share rooms with COVID-19 patients. Bandaged eyes had become so common that they become a symbol for protesters. Among protestors the injured are considered "martyrs" and "proof of police brutality". The eyes bandages featuring in the "A Rapist in Your Path" performances are references to the victims that have suffered eye injuries 2019–2020 Chilean protests. Singer-songwriter Nano Stern released the song Regalé mis ojos (lit. "I gave away my eyes") on November 19 paying homage to Gustavo Gatica, who lost both eyes in the protests. Álex Anwandter covered one of his eyes in homage to the injured during the Olmué Festival in January 2020. Anwandter then added that he hoped that "this time, in difference to the [Pinochet] dictatorship, there will be accountability. And the politically responsible, such as Piñera, will pay." During Mon Laferte's show in the Viña del Mar International Song Festival members of her crew covered their eye in reference to the eye injuries. Fabiola Campillai and Gustavo Gatica, two well-known victims, were part of campaign advertising for the "Approve" option in the 2020 Chilean national plebiscite held on October 25, 2020. Gatica subsequently received a string of offers to run in the 2021 Chilean Constitutional Convention election which he declined.

Mobile Phone Tracking
Mobile phone tracking is a process for identifying the location of a mobile phone, whether stationary or moving. Localization may be effected by a number of technologies, such as using multilateration of radio signals between (several) cell towers of the network and the phone, or simply using GPS. To locate a mobile phone using multilateration of radio signals, it must emit at least the idle signal to contact the next nearby antenna tower, but the process does not require an active call. The Global System for Mobile Communications (GSM) is based on the phone's signal strength to nearby antenna masts. Mobile positioning may include location-based services that disclose the actual coordinates of a mobile phone, which is a technology used by telecommunication companies to approximate the location of a mobile phone, and thereby also its user.

Artemisia Armeniaca
Artemisia /ˌɑːrtɪˈmiːziə/ is a large, diverse genus of plants with between 200 and 400 species belonging to the daisy family Asteraceae. Common names for various species in the genus include mugwort, wormwood, and sagebrush. Artemisia comprises hardy herbaceous plants and shrubs, which are known for the powerful chemical constituents in their essential oils. Artemisia species grow in temperate climates of both hemispheres, usually in dry or semiarid habitats. Notable species include A. vulgaris (common mugwort), A. tridentata (big sagebrush), A. annua (sagewort), A. absinthium (wormwood), A. dracunculus (tarragon), and A. abrotanum (southernwood). The leaves of many species are covered with white hairs. Most species have strong aromas and bitter tastes from terpenoids and sesquiterpene lactones, which discourage herbivory, and may have had a selective advantage. The small flowers are wind-pollinated. Artemisia species are used as food plants by the larvae of a number of Lepidoptera species. Some botanists split the genus into several genera, but DNA analysis does not support the maintenance of the genera Crossostephium, Filifolium, Neopallasia, Seriphidium, and Sphaeromeria; three other segregate genera -- Stilnolepis, Elachanthemum, and Kaschgaria -- are maintained by this evidence. Occasionally, some of the species are called sages, causing confusion with the Salvia sages in the family Lamiaceae.

Video Feedback
Video feedback is the process that starts and continues when a video camera is pointed at its own playback video monitor. The loop delay from camera to display back to camera is at least one video frame time, due to the input and output scanning processes; it can be more if there is more processing in the loop.
