Emergence of Synchronous Oscillations in Neural Networks Excited by Noise
, 2005 The presence of noise in non linear dynamical systems can play a constructive role, increasing the degree of order and coherence or evoking improvements in the performance of the system. An example of this positive influence in a biological system is the

Piezoresistivity and conductance anisotropy of tunneling-percolating systems [PDF]
, 2002 Percolating networks based on interparticle tunneling conduction are shown to yield a logarithmic divergent piezoresistive response close to the critical point as long as the electrical conductivity becomes nonuniversal. At the same time, the piezoresistivity or, equivalently, the conductivity anisotropy exponent $\lambda$ remains universal also when ...

SENSORY REGRESSION TIME FROM SUBARACHNOID BLOCK WITH HYPERBARIC 0.75% BUPIVACAINE IN THE OBESE PATIENT [PDF]
, 1989 The purpose of this study was to determine if obese patients have a different sensory regression time from subarachnoid block than non-obese patients using hyperbaric 0.75% bupivacaine. A quasi-experimental design was used. Twenty patients were separated

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Current radiotherapy practices rely on manual contouring of CT scans, which is time‐consuming, prone to variability, and requires highly trained experts. There is a need for more efficient and consistent contouring methods. This study evaluated the performance of the Varian Ethos AI auto‐contouring tool to assess its potential integration into

Extent of error control in neural networks [PDF]
arXiv, 2016 The article sets and solves the task to control an error of the artificial neural network with variable signal conductivity. This kind of neural networks was especially developed to construct timetables. Behavior of such a neural network can be described as dynamic system control problem.

Semi‐automated hippocampal avoidance whole‐brain radiotherapy planning
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background Hippocampal avoidance whole‐brain radiotherapy (HA‐WBRT) is designed to spare cognitive function by reducing radiation dose to the hippocampus during the treatment of brain metastases. Current manual planning methods can be time‐consuming and may vary in quality, necessitating the development of automated approaches to streamline ...

Myelin-induced gain control in nonlinear neural networks
Communications PhysicsMyelin surrounds axonal membranes to increase the conduction velocity of nerve impulses and thus reduce communication delays in neural signaling. Changes in myelination alter the distribution of delays in neural circuits, but the implications for their ...
