The absolute threshold for touch is a bee's wing dropping onto a person's cheek from one centimeter (0.4 inches) away. Different parts of the body are more sensitive to touch, so this varies from one body part to the next (20). As people age, the absolute threshold for touch becomes larger, especially after age 65.
A logical sentence (,, …,,) is realized by a neural network iff there exists a time-delay , a neuron in the network, and an initial state for the non-peripheral neurons + (), …, (), such that for any time , the truth-value of the logical sentence is equal to the state of the neuron at time +.
In electrophysiology, the threshold potential is the critical level to which a membrane potential must be depolarized to initiate an action potential. In neuroscience, threshold potentials are necessary to regulate and propagate signaling in both the central nervous system (CNS) and the peripheral nervous system (PNS).
In measuring sensory threshold, noise must be accounted for. Signal noise is defined as the presence of extra, unwanted energy in the observational system which obscures the information of interest. As the measurements come closer to the absolute threshold, the variability of the noise increases, causing the threshold to be obscured. [5]
Conversely, existential sentences are upward absolute from a structure to any structure containing it. Two structures are defined to be elementarily equivalent if they agree about the truth value of all sentences in their shared language, that is, if all sentences in their language are absolute between the two structures.

Florida has the country’s highest number of exonerations at 30 and will likely soon have the lowest jury threshold for a death sentence at 8-4.
The absolute threshold of hearing (ATH), also known as the absolute hearing threshold or auditory threshold, is the minimum sound level of a pure tone that an average human ear with normal hearing can hear with no other sound present. The absolute threshold relates to the sound that can just be heard by the organism.
