Rapid contrast gain reduction following motion adaptation [PDF]
Journal of Experimental Biology, 2011 SUMMARY Neural and sensory systems adapt to prolonged stimulation to allow signaling across broader input ranges than otherwise possible with the limited bandwidth of single neurons and receptors. In the visual system, adaptation takes place at every stage of processing, from the photoreceptors that adapt to prevailing luminance ...

Nature Communications, 2020 Bacterial chemoreceptors have multiple methylation sites, but whether the order of methylation matters is unclear. Here, the authors show that sequentially ordered methylation is critical for perfect adaptation and for attenuating the trade-off between ...

The generalized super‐twisting algorithm with adaptive gains [PDF]
International Journal of Robust and Nonlinear Control, 2020 AbstractIn this article, a novel adaptive generalized super‐twisting algorithm (GSTA) is proposed for a class of systems whose perturbations and uncertain control coefficients may depend on both time and state. The proposed approach uses dynamically adapted control gains, and it is proven that this ensures global finite‐time convergence.

Robust gain scheduling techniques for adaptive control [PDF]
2009 European Control Conference (ECC), 2009 Robust and gain-scheduling analysis and design techniques are used to realize an adaptive controller. LFT representations of the plant and controller are used so that the stability and performance properties of the adaptive scheme can be studied off-line, and the on-line computational time for implementing the LFT controller is reduced. This controller

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...

Pushing it to the Limit: Adaptation with Dynamically Switching Gain Control
EURASIP Journal on Advances in Signal Processing, 2007 With this paper we propose a model to simulate the functional aspects of light adaptation in retinal photoreceptors. Our model, however, does not link specific stages to the detailed molecular processes which are thought to mediate adaptation in real ...

How adaptation currents change threshold, gain and variability of neuronal spiking [PDF]
, 2013 Many types of neurons exhibit spike rate adaptation, mediated by intrinsic slow $\mathrm{K}^+$-currents, which effectively inhibit neuronal responses. How these adaptation currents change the relationship between in-vivo like fluctuating synaptic input ...
