Vigil (Spacecraft)

Vigil, formerly known as Lagrange, is a planned solar weather mission by the European Space Agency (ESA). It envisions two spacecraft to be positioned at Lagrangian points L1 and L5. Monitoring space weather includes events such as solar flares, coronal mass ejections, geomagnetic storms, solar proton events, etc. Monitoring would help predict arrival times at the Earth and any potential effect on infrastructure. The Vigil spacecraft are anticipated to launch in the mid 2020s. On 17 May 2021, ESA began soliciting design concept studies from various European industrial and scientific consortiums for the mission. A final design will be selected after approximately 18 months, in late 2022. Simultaneously, the ESA announced the No-Name Mission contest to replace the placeholder Lagrange name. The winning name, Vigil, was announced on 10 February 2022.

Mood Congruence

Mood congruence is a type of recall biased mood congruent memory, not to be mistaken with mood-dependent memory, where an individual's current mood or affective state determines the affective association of the memories that are recalled. In psychology, memories are said to be mood-congruent if they are consistent with a patient's mood or mental disorder. Mental disorders regarding mood congruence are exampled as clinical depression or bi-polar disorder.

Ousia

Ousia (/ˈuːziə, ˈuːsiə, ˈuːʒə, ˈuːʃə/; Ancient Greek:) is an important philosophical and theological term, originally used in ancient Greek philosophy, then later in Christian theology. It was used by various ancient Greek philosophers, like Plato and Aristotle, as a primary designation for philosophical concepts of essence or substance. In contemporary philosophy, it is analogous to English concepts of being and ontic. In Christian theology, the concept of θεία ουσία (divine essence) is one of the most important doctrinal concepts, central to the development of trinitarian doctrine. The Ancient Greek term ousia was translated in Latin as essentia or substantia, and hence in English as essence or substance.

SMPTE 292M

SMPTE 292 is a digital video transmission standard published by the Society of Motion Picture and Television Engineers (SMPTE) which expands upon SMPTE 259 and SMPTE 344 allowing for bit-rates of 1.485 Gbit/s, and 1.485/1.001 Gbit/s. These bit-rates are sufficient for and often used to transfer uncompressed high-definition video. This standard is usually referred to as HD-SDI; it is part of a family of standards that define a Serial Digital Interface based on a coaxial cable, intended to be used for transport of uncompressed digital video and audio in a television studio environment. The “M” designator was originally introduced to signify metric dimensions. It is no longer used in listings or filenames. Units of the International System of Units (SI) are the preferred units of measurement in all SMPTE Engineering Documents.

Mitteleuropa

Mitteleuropa (pronounced [ˈmɪtl̩ʔɔʏˌroːpa]), meaning Middle Europe, is one of the German terms for Central Europe. The term has acquired diverse cultural, political and historical connotations. The Prussian vision of Mitteleuropa was a pan-Germanist state-centric imperium, an idea that was later adopted in a modified form by National Socialist geopoliticians.

Andalusian Arabic

Andalusian Arabic, also known as Andalusi Arabic, was a variety or varieties of Arabic spoken in Al-Andalus, the regions of the Iberian Peninsula (modern Spain and Portugal) under Muslim rule (and for some time after) from the 9th century to the 17th century. It became an extinct language in Iberia after the expulsion of the former Hispanic Muslims, which took place over a century after the Granada War by the Catholic Monarchs of Spain. Once widely spoken in Iberia, the expulsions and persecutions of Arabic speakers caused an abrupt end to the language's use on the peninsula. Its use continued to some degree in North Africa after the expulsion, although Andalusi speakers were rapidly assimilated by the Maghrebi communities to which they fled.

MG-RAST

MG-RAST is an open-source web application server that suggests automatic phylogenetic and functional analysis of metagenomes. It is also one of the biggest repositories for metagenomic data. The name is an abbreviation of Metagenomic Rapid Annotations using Subsystems Technology. The pipeline automatically produces functional assignments to the sequences that belong to the metagenome by performing sequence comparisons to databases in both nucleotide and amino-acid levels. The applications supplies phylogenetic and functional assignments of the metagenome being analysed, as well as tools for comparing different metagenomes. It also provides a RESTful API for programmatic access. The server was created and maintained by Argonne National Laboratory from the University of Chicago. In December 29 of 2016, the system had analyzed 60 terabase-pairs of data from more than 150,000 data sets. Among the analyzed data sets, more than 23,000 are available to the public. Currently, the computational resources are provided by the DOE Magellan cloud at Argonne National Laboratory, Amazon EC2 Web services, and a number of traditional clusters.

Covert Facial Recognition

Joachim Bodamer created the term prosopagnosia in 1947, which is a disorder where individuals have an inability to recognize faces of people. Individuals with this disorder do not have the ability to overtly recognize faces, but discoveries have been made showing that people with this disorder have the ability to covertly recognize faces. Covert facial recognition is the unconscious recognition of familiar faces by people with prosopagnosia. The individuals who express this phenomenon are unaware that they are recognizing the faces of people they have seen before. There are two types of prosopagnosia, congenital and acquired. Congenital prosopagnosia is an inability to recognize faces without a history of brain damage; while acquired prosopagnosia is caused by damage to the right occipital-temporal region of the brain. In the 1950s it was theorized that the right cerebral hemisphere was involved in facial recognition and in the 1960s this theory was supported by many experiments. Although the ability for overt facial recognition is inhibited in patients with prosopagnosia, there have been many studies done which show that some of these individuals may have the ability to recognize familiar faces covertly. These experiments have used behavioral and physiological measures in order to demonstrate covert facial recognition. A common physiological measure that is used is the measure of autonomic activity by using skin-conductance responses (SCR) which show a larger response in individuals with prosopagnosia who are shown pictures of familiar faces compared to pictures of unfamiliar faces.
