The oculomotor neural integrator is a brainstem nucleus that stores the short term memory of eye position during gaze holding. This neural integrator is believed to perform temporal integration of transient eye velocity input using positive feedback. Such models of integration are known to suffer from a fine-tuning problem [9] since changes in the amount of feedback by less than 10% can de-tune...

Knowledge of accuracy of numerical integration is important for composing an overall numerical error budget; in orbit determination and propagation for space surveillance, there is frequently a computation time-accuracy tradeoff that must be balanced. There are several techniques to assess the accuracy of a numerical integrator. In this paper we compare some of those techniques: comparison with...

Synapses play a critical role in memory, learning, and cognition. Their main functions include converting pre-synaptic voltage spikes to post-synaptic currents, as well scaling the input signal. Several brain-inspired architectures have been proposed emulate behavior of biological synapses. While these are useful explore properties nervous systems, challenge making biocompatible flexible circui...

The article offers a new approach towards the parameterisation of perfume and cosmetic names, in particular social status reflection naming integrator these goods. It being bearer parameters correlates with hyper-informative units as information parameter. Four integrants correspond to four sub-informative units. Being identified structure integrator, differ according parameters. There is 1 bra...

We construct a symplectic, globally defined, minimal-variable, equivariant integrator on products of 2-spheres. Examples of corresponding Hamiltonian systems, called spin systems, include the reduced free rigid body, the motion of point vortices on a sphere, and the classical Heisenberg spin chain, a spatial discretisation of the Landau–Lifshitz equation. The existence of such an integrator is ...

there are different approaches to business model categorization. [5] in a point of view, the e-business model patterns can be categorized to content provider, direct to customer (d2c), full-service provider, intermediary, shared infrastructure, value net integrator, virtual community, and whole of enterprise.

We derive an explicit second order reversible Poisson integrator for symmetric rigid bodies in space (i.e. without a fixed point). The integrator is obtained by applying a splitting method to the Hamiltonian after reduction by the S1 body symmetry. In the particular case of a magnetic top in an axisymmetric magnetic field (i.e. the Levitron) this integrator preserves the two momentum integrals....
