TRACE (Psycholinguistics)
TRACE is a connectionist model of speech perception, proposed by James McClelland and Jeffrey Elman in 1986. It is based on a structure called "the Trace," a dynamic processing structure made up of a network of units, which performs as the system's working memory as well as the perceptual processing mechanism. TRACE was made into a working computer program for running perceptual simulations. These simulations are predictions about how a human mind/brain processes speech sounds and words as they are heard in real time.

Traditionalist School
The Traditionalist School is a group of 20th- and 21st-century thinkers who believe in the existence of a perennial wisdom or perennial philosophy, primordial and universal truths which form the source for, and are shared by, all the major world religions. The principal thinkers in this tradition are René Guénon, Ananda Coomaraswamy and Frithjof Schuon. Other important thinkers in this tradition include Titus Burckhardt, Martin Lings, Jean-Louis Michon, Marco Pallis, Huston Smith, Seyyed Hossein Nasr, Jean Borella, and Julius Evola.[note 1]

Human Microbiota
The human microbiota is the aggregate of microorganisms that resides on or within any of a number of human tissues and biofluids, including the skin, mammary glands, placenta, seminal fluid, uterus, ovarian follicles, lung, saliva, oral mucosa, conjunctiva, biliary and gastrointestinal tracts. They include bacteria, archaea, fungi, protists and viruses. Though micro-animals can also live on the human body, they are typically excluded from this definition. The human microbiome refers specifically to the collective genomes of resident microorganisms. Humans are colonized by many microorganisms; the traditional estimate is that the average human body is inhabited by ten times as many non-human cells as human cells, but more recent estimates have lowered that ratio to 3:1 or even to approximately the same number. Some microorganisms that colonize humans are commensal, meaning they co-exist without harming humans; others have a mutualistic relationship with their human hosts.:700 Conversely, some non-pathogenic microorganisms can harm human hosts via the metabolites they produce, like trimethylamine, which the human body converts to trimethylamine N-oxide via FMO3-mediated oxidation. Certain microorganisms perform tasks that are known to be useful to the human host but the role of most of them is not well understood. Those that are expected to be present, and that under normal circumstances do not cause disease, are sometimes deemed normal flora or normal microbiota. The Human Microbiome Project took on the project of sequencing the genome of the human microbiota, focusing particularly on the microbiota that normally inhabit the skin, mouth, nose, digestive tract, and vagina. It reached a milestone in 2012 when it published its initial results.

Taiji
Taiji or Tai chi (simplified Chinese: 太极; traditional Chinese: 太極; pinyin: tàijí; literally: 'great pole') is a Chinese cosmological term for the "Supreme Ultimate" state of undifferentiated absolute and infinite potential, the oneness before duality, from which Yin and Yang originate. It can be compared with the old Wuji (無極, "without pole"). The term Taiji and its other spelling T'ai chi (using Wade–Giles as opposed to Pinyin) are most commonly used in the West to refer to Taijiquan (or T'ai chi ch'uan, 太極拳), an internal martial art, Chinese meditation system and health practice. This article, however, refers only to the use of the term in Chinese philosophy and in Confucianism, Taoism and Buddhism.

Illumina Dye Sequencing
Illumina dye sequencing is a technique used to determine the series of base pairs in DNA, also known as DNA sequencing. The reversible terminated chemistry concept was invented by Bruno Canard and Simon Sarfati at the Pasteur Institute in Paris. It was developed by Shankar Balasubramanian and David Klenerman of Cambridge University, who subsequently founded Solexa, a company later acquired by Illumina. This sequencing method is based on reversible dye-terminators that enable the identification of single nucleotides as they are washed over DNA strands. It can also be used for whole-genome and region sequencing, transcriptome analysis, metagenomics, small RNA discovery, methylation profiling, and genome-wide protein-nucleic acid interaction analysis.

Cryogenic Particle Detectors
Cryogenic particle detectors operate at very low temperature, typically only a few degrees above absolute zero. These sensors interact with an energetic elementary particle (such as a photon) and deliver a signal that can be related to the type of particle and the nature of the interaction. While many types of particle detectors might be operated with improved performance at cryogenic temperatures, this term generally refers to types that take advantage of special effects or properties occurring only at low temperature.

Trinity: Souls of Zill O’ll
Trinity: Souls of Zill O’ll, known in Japan as Trinity: Zill O'll Zero (トリニティ ジルオール ゼロ, Toriniti Jiru Ōru Zero), is an action fantasy role-playing video game developed by Omega Force, set in part of the Zill O'll series, which had previously appeared on PlayStation, PlayStation 2 and PlayStation Portable. The game is a prequel, taking place five years before the events in Zill O'll. Downloadable content that included additional quests and alternate costumes for the main party was released exclusively in Japan.

Event
In philosophy, events are objects in time or instantiations of properties in objects. On some views, only changes in the form of acquiring or losing a property can constitute events, like the lawn's becoming dry. According to others, there are also events that involve nothing but the retaining of a property, e.g. the lawn's staying wet. Events are usually defined as particulars that, unlike universals, cannot repeat at different times. Processes are complex events constituted by a sequence of events. But even simple events can be conceived as complex entities involving an object, a time and the property exemplified by the object at this time. Traditionally, metaphysicians tended to emphasize static being over dynamic events. This tendency has been opposed by so-called process philosophy or process ontology, which ascribes ontological primacy to events and processes.

R2 Signalling
R2 is a 1950s- and 1970s-era channel-associated-signalling signalling protocol used outside of the former Bell System, mostly Europe and Latin America, to convey information along a telephone trunk between two telephone switches in order to establish a single telephone call along that trunk. R2 is the name given to two broad protocol groups: R2 line signalling and R2 register signalling.
