Core (functional analysis)

In functional analysis, a discipline within mathematics, a core may be:

Core (anatomy)

In common parlance, the core of the body is broadly considered to be the torso. Functional movements are highly dependent on this part of the body, and lack of core muscular development can result in a predisposition to injury. The major muscles of the core reside in the area of the belly and the mid and lower back (not the shoulders), and peripherally include the hips, the shoulders and the neck.

Muscles

Major muscles included are the pelvic floor muscles, transversus abdominis, multifidus, internal and external obliques, rectus abdominis, erector spinae (sacrospinalis) especially the longissimus thoracis, and the diaphragm. Minor core muscles include the latissimus dorsi, gluteus maximus, and trapezius.

Functions of the core

The core is used to stabilize the thorax and the pelvis during dynamic movement and it also provides internal pressure to expel substances (vomit, feces, carbon-laden air, etc.).

Continence is the ability to withhold bowel movements, and urinary stress incontinence (the lack of bladder control due to pelvic floor dysfunction) can result from weak core musculature.

Neuron (journal)

Neuron is a biweekly peer-reviewed scientific journal of neuroscience published by Cell Press. It was established in 1988.

Hartmann Neuron

The Hartmann Neuron was an electronic musical instrument designed and built by industry designer Axel Hartmann of the German company Hartmann Music in the years 2001–2005. The Neuron synthesizer used an Artificial Neural Network to create a digital computer model from sampled sounds, implementing a new synthesis technology which was developed by Stephan Bernsee at Prosoniq. This computer model could then be used to resynthesize a new sound, giving the player control over "musical" aspects such as instrument body size, material and other acoustic properties. This parametric approach is very different from the more mathematical approaches of other synthesizers.

Critique

Even though the instrument was awarded numerous prizes for innovation it was difficult to operate due to its limited display capabilities, which made adjusting the tonal qualities of a sound a tedious trial and error process. Given the very high price of the instrument (around 5000 USD) many people felt that manipulating a wireframe model of a sound only by ear did not allow for the amount of control necessary for such a complex operation. However, combined with a sample editor, the included Modelmaker software & MIDI control via sequencing, this difficulty can be somewhat rectified, albeit without the aid of the 3D image of the model.

Neuron (software)

Neuron is a simulation environment for modeling individual neurons and networks of neurons. As of version 7.3, Neuron is capable of handling diffusion-reaction models, and integrating diffusion functions into models of synapses and cellular networks. It was primarily developed by Michael Hines, John W. Moore, and Ted Carnevale at Yale and Duke.

NEURON models individual neurons via the use of sections which are subdivided into individual compartments by the program, instead of requiring the user to manually create the compartments. The primary scripting language that is used to interact with it is hoc but a Python interface is also available. The programs for it can be written interactively in a shell, or loaded from a file. NEURON supports parallelization via the MPI protocol. Also, starting with NEURON 7.0 parallelization is possible via internal multithreaded routines, for use on computers with multiple cores. The properties of the membrane channels of the neuron are simulated using compiled mechanisms written using the NMODL language or by compiled routines operating on internal data structures that are set up with a GUI tool (Channel Builder).
