Overview
Genes can be viewed as
nodes in a network , with input being proteins such as transcription factors , ... the new state of a node is a boolean function of the prior states of the
nodes with arrows pointing towards it.
The validity of the model can be ...
Apoptosis
... a malignant mutation) or with foreign antigen produced as a consequence of a viral infection. After becoming activated, they migrate out of the lymph
nodes in which they reside, proliferate, recognize the affected cells and commit them to programmed cell death.
The receptors in immature B and T cell ...
Axon
... neurons and oligodendrocytes insulating those of the central nervous system . Along myelinated nerve fibers, gaps in the sheath known as
nodes of Ranvier occur at evenly spaced intervals, enabling an especially rapid mode of electrical impulse propagation called saltation .
The axons of ...
Immune system
... material. It may be broken down into the adaptive immune system (only found in vertebrates [1] ), composed of four lymphoid organs ( thymus , lymph
nodes , spleen and submucosal lymphoid nodules) and the group motile cells that are involved in the body's defense against foreign bodies. The term may ...
Immunology
... would later prove to be part of the immune system. The key organs of the immune system are thymus , spleen , bone marrow , lymph vessels , lymph
nodes and secondary lymphatic tissues such as tonsils and adenoids ) and skin . The major organs, the thymus and spleen, are examined histologically ...
Neuron
... peripheral nervous system. The myelin sheath in peripheral nerves normally runs along the axon in sections about 1 mm long, punctuated by unsheathed
nodes of Ranvier . Multiple sclerosis is a neurological disorder which results from abnormal demyelination of peripheral nerves. Neurons with ...
Phylogenetic tree
... ancestor of the descendants, and edge lengths correspond to time estimates. Each node in a phylogenetic tree is called a taxonomic unit. Internal
nodes are generally referred to as Hypothetical Taxonomic Units (HTUs) as they cannot be directly observed.
A rooted phylogenetic tree is a directed ...
Replication
... also Coda and RAID .
Another example of using replication one may find in distributed shared memory systems, where it may happened that many
nodes of the system share the same page of the memory - which usually means, that each node have separate copy (replica) of this page.
In statistics ...
Taxonomy
... of classifications for a given set of objects. At the top of this structure is a single classification, the root node, that applies to all objects.
nodes below this root are more specific classifications that apply to subsets of the total set of classified objects. So for instance in Carolus Linnaeus ...
