Genetic, epigenetic, and proteomic studies have often focused on individuals with specific sleep disorders compared to unaffected controls, or the effects of sleep deprivation compared to undisturbed sleep. However, such studies can also be informed by examining individuals with varying degrees of a positive trait, or resilience to perturbation.

If the first step of an analysis is a perturbation step, the base state is determined from the initial conditions (Initial conditions in Abaqus/Standard and Abaqus/Explicit). Initial condition definitions that directly define solution variables, such as velocity, cannot be …

Secular definition, of or relating to worldly things or to things that are not regarded as religious, spiritual, or sacred; temporal: secular interests. See more.

NEST offers convenient and efficient commands to define and connect large networks, ranging from algorithmically determined connections to data-driven connectivity. NEST lets you inspect and modify the state of each neuron and each connection at any time during a simulation. NEST is fast and memory efficient.

Resetting the Circadian Clock. The health effects of light pollution have not been as well defined for humans as for wildlife, although a compelling amount of epidemiologic evidence points to a consistent association between exposure to indoor artificial nighttime light and health problems such as breast cancer, says George Brainard, a professor of neurology at Jefferson Medical …

Stability Equilibrium solutions can be classified into 3 categories: - Unstable: solutions run away with any small change to the initial conditions. - Stable: any small perturbation leads the solutions back to that solution. - Semi-stable: a small perturbation is stable on one side and unstable on the other. Linear first-order ODE technique. Standard form The standard form of a first-order ...
