PET radiotracers, or positron emission tomography radiotracers, are biologically active molecules labeled with a radioactive isotope that emits positrons. These tracers are used in PET imaging, a type of nuclear medicine that provides valuable insights into the metabolic processes of tissues and organs in the body. In PET imaging, a radiotracer is introduced into the body, typically through injection.
Single scan dynamic molecular imaging is a cutting-edge imaging technique that allows researchers to visualize dynamic processes at the molecular level in real time. This method typically combines advanced imaging technologies, such as fluorescence microscopy or computational imaging, with sophisticated analysis techniques to observe molecular interactions, conformational changes, and dynamic behaviors of biomolecules, cells, or tissues.
Former dwarf planet candidates refer to celestial bodies in the solar system that were considered for classification as dwarf planets but ultimately were not designated as such, either due to lack of sufficient evidence or because they did not meet all the criteria established by the International Astronomical Union (IAU) for dwarf planet status. To be classified as a dwarf planet, a celestial body must: 1. Orbit the Sun.
(119951) 2002 KX14 is a trans-Neptunian object, classified as a centaur or a scattered disc object. It was discovered in May 2002 and is part of a group of icy bodies located beyond the orbit of Neptune in the outer solar system. Due to its size and characteristics, it falls under the category of minor planets or asteroids. These types of objects can offer valuable insights into the early solar system and the formation of planetary bodies.
(24835) 1995 SM55 is a numbered asteroid that is part of the main asteroid belt in our solar system. It was discovered on September 23, 1995, and is classified as an Apollo-type near-Earth asteroid, which means it has an orbit that brings it close to Earth's orbit. The asteroid is a subject of interest for astronomers and researchers due to its potential for studying the properties of asteroids and their orbits.
(278361) 2007 JJ43 is an asteroid that is part of the asteroid belt located between Mars and Jupiter. It was discovered on May 8, 2007, and is classified as a member of the main belt asteroids. The designation "278361" refers to its specific catalog number, while "2007 JJ43" is the provisional designation given upon its discovery. Like many asteroids, it provides valuable information about the early solar system and the formation of planetary bodies.
(523706) 2014 HF200 is a designated asteroidal object within our solar system. It is classified as a near-Earth object (NEO), specifically an Apollo-type asteroid, which means its orbit crosses that of Earth. Discovered in 2014, it has been studied for its physical characteristics, orbital parameters, and potential impact risks. As a small Solar System body, 2014 HF200 may provide insights into the formation and evolution of our solar system.
(523727) 2014 NW65 is a designation for a trans-Neptunian object (TNO) that was discovered in 2014. It is classified as a cubewano, which is a type of icy body located in the Kuiper Belt that does not have significant gravitational influences from Neptune. These objects often have stable orbits and are sometimes referred to as "classical" Kuiper Belt Objects (KBOs).
(523794) 2015 RR245 is a trans-Neptunian object (TNO) located in the outer region of the Solar System, specifically in the Kuiper Belt. It is classified as a dwarf planet candidate due to its size and characteristics.
(524435) 2002 CY248 is a trans-Neptunian object (TNO) and a centaur, which is a class of small celestial bodies located in the outer Solar System, often between the orbits of Jupiter and Neptune. This specific object was discovered in 2002 and is known for its properties as a detached object, meaning its orbit does not interact significantly with Neptune.
(527603) 2007 VJ305 is a classified asteroid that is part of the main belt of asteroids in our solar system. Identified by the Minor Planet Center, it was discovered in 2007. Like many asteroids, it can provide valuable information about the early solar system since they are considered remnants from the formation of the solar system approximately 4.6 billion years ago.
(505448) 2013 SA100 is a designation for a specific asteroid discovered in the asteroid belt. It is classified as a "trans-Neptunian object" (TNO), which generally refers to objects located beyond the orbit of Neptune. The asteroid was identified in 2013, and its numbering (505448) indicates that it has been officially cataloged.
(589683) 2010 RF43 is an asteroid that is part of the asteroid belt. It was discovered on September 5, 2010, and is classified under the category of near-Earth objects (NEOs). The designation "2010 RF43" indicates the year of its discovery (2010) and the order of its identification during that year (RF43).
(612584) 2003 QX113 is a trans-Neptunian object located in the Kuiper Belt. It is classified as a centaur, which is a type of minor planet that orbits between the asteroid belt and the outer planets, specifically between Jupiter and Neptune. This designation indicates that it exhibits characteristics of both asteroids and comets.
Deixis is a linguistic term that refers to words or phrases that require contextual information to convey meaning fully. These expressions are often referred to as "deictic expressions" or "indexicals," and they can relate to various aspects of context, including the speaker, the listener, time, place, and even the discourse itself. There are several types of deixis: 1. **Person Deixis**: Refers to the participants in a conversation.
A discourse marker is a word or phrase that helps to organize, manage, or clarify discourse in spoken or written communication. These markers serve various functions, such as signaling the structure of the conversation, indicating a change in topic, providing emphasis, or guiding the listener's understanding of the speaker's intent.
Endophora is a linguistic term that refers to a type of reference where a word or phrase relies on something mentioned within the same context, particularly within a text or discourse. It contrasts with exophora, which refers to references that draw on external contexts or knowledge outside of the discourse. In endophoric references, terms such as pronouns or definite descriptions refer back to previously mentioned entities or ideas within the same text. For example, in the sentence "The cat is on the roof.
Evidentiality is a linguistic feature that indicates the source of information expressed in a statement or claim. It conveys the speaker's assessment of the reliability of the information and how they came to know it. Evidentiality is particularly important in languages that grammatically encode this information, allowing speakers to indicate whether they are speaking from direct experience, hearsay, inference, or other sources.
