Examples of Two-component systems in the following topics:
-
- The following examples refer to a two component system, in which one monomer is designated A and the other B.
-
- Two-component systems couple mechanism to allow organisms to sense and respond to changes in many different environmental conditions.
- Two component signaling systems are widely occurring in prokaryotes whereas only a few two-component systems have been identified in eukaryotic organisms.
- A variant of the two-component system is the phospho-relay system.
- Signal transducing histidine kinases are the key elements in two-component signal transduction systems.
- Describe the structure and function of a bacterial two-component regulatory system

- The nervous system can be divided into two major parts—the central nervous system (CNS) and the peripheral nervous system (PNS).
- The peripheral nervous system includes a large system of nerves that are linked to the brain and spinal cord.
- The PNS can be further subdivided into the autonomic nervous system and the somatic nervous system.
- The autonomic nervous system is made of two components, which work in opposition to one another: the sympathetic nervous system, responsible for the body's "fight-or-flight" response to danger, and the parasympathetic nervous system, which calms the body back down.
- The nervous system of the human body, including the brain and spinal cord (central nervous system) and all the nerves of the body (peripheral nervous system).
-
- Two additional sensory systems are proprioception (which interprets body position) and the vestibular system (which interprets balance).
- However, recent advances in science have expanded this canonical list of five sense systems to include two more: proprioception, which is the sense of the positioning of parts of the body; and the vestibular system, which senses gravity and provides balance.
- Kinesthesia is a key component in muscle memory and hand-eye coordination.
- While the terms proprioception and kinesthesia are often used interchangeably, they actually have many different components.
- There are two main components of the vestibulum: the semicircular canal system, which indicates rotational movements; and the otoliths, which indicate linear accelerations.
-
- The internal energy of a system is the sum of all kinetic and potential energy in a system.
- However, a system does contain a quantifiable amount of energy called the internal energy of a system.
- Internal energy has two components: kinetic energy and potential energy.
- We can also think of the internal energy as the sum of all the energy states of each component in the system:
- We can calculate a small change in internal energy of the system by considering the infinitesimal amount of heat δQ added to the system minus the infinitesimal amount of work δW done by the system:
-
- As illustrated in Exhibit 41, an Information System is comprised of two sub-systems, a Social sub-system and a Technology sub-system.
- An example of a telecommunication system is a telephone network, which allows two callers to interact by voice over a distance.
- The people component of an information system encompasses all those individuals who are directly involved with the system.
- The structure (or organizational structure) component of information systems refers to the relationship among the individuals in the people component.
- More subtly, the four components of information systems must work together for the systems to perform.
-
- It is divided into two parts: One fixed and independent of the expert system—the inference (reasoning) engine, and one variable—the knowledge base.
- In the 1980s, a third component was added to most expert systems: A dialog interface to communicate with users.
- Knowledge-based systems are systems based on the methods and techniques of artificial Intelligence.
- Their core components are
- Knowledge base systems (KBS) go beyond the decision support philosophy to incorporate expert system technology into the decision-making framework.
-
- Another way of adding vectors is to add the components.
- To add vectors, merely express both of them in terms of their horizontal and vertical components and then add the components together.
- This can be seen by adding the horizontal components of the two vectors ($4+4$) and the two vertical components ($3+3$).
- These additions give a new vector with a horizontal component of 8 ($4+4$) and a vertical component of 6 ($3+3$).
- To subtract vectors by components, simply subtract the two horizontal components from each other and do the same for the vertical components.
-
- For directed graphs (in contrast to simple graphs), we can define two different kinds of components.
- A strong component requires that there be a directed path from A to B in order for the two to be in the same component.
- Let's look instead at the network of large donors to California political campaigns, where the strength of the relation between two actors is defined by the number of times that they contributed on the same side of an issue.
- UCINET provides two algorithms for doing a census of components.
- Network>Regions>Components>Valued Graphs can be used to examine the hierarchy of components as the cut-off value of tie strength is increasingly relaxed.
-
- The digestive system is an endoderm-derived structure that begins developing about the fourth week of embryogenesis.
- Although these terms are often used in reference to segments of the primitive gut, they are also used regularly to describe components of the definitive gut as well.
- Components derived from the gut proper, including the stomach and colon, develop as swellings or dilatations of the primitive gut.
- The foregutis the esophagus to first two sections of the duodenum, liver, gallbladder, and superior portion of pancreas.
- The midgut is the lower duodenum, to the first two-thirds of the transverse colon lower duodenum, jejunum, ileum, cecum, appendix, ascending colon, and first two-thirds of the transverse colon.
