Push–pull quinoidal porphyrins [PDF]
Organic & Biomolecular Chemistry, 2018 Quinoidal porphyrins with electron-donating 1,3-dithiolane and electron-withdrawing dicyanomethylene groups form tightly π-stacked layer structures, despite their curved geometries and bulky aryl substituents. The crystal structures of these quinoidal porphyrins indicate that there is no significant contribution from singlet biradical or zwitterionic ...

Farmers’ perceived pathways for further intensification of push-pull systems in Western Kenya
Frontiers in Sustainable Food Systems, 2023 Push-pull technology provides farmers in East Africa with an eco-friendly strategy that increases crop yield and household income in smallholder cereal systems by controlling pests and improving soil health. Though promising for a sustainably intensified

Push-Pull Control of Motor Output [PDF]
, 2012 Inhibition usually decreases input–output excitability of neurons. If, however, inhibition is coupled to excitation in a push–pull fashion, where inhibition decreases as excitation increases, neuron excitability can be increased. Although the presence of

Predictive model of the human muscle fatigue: application to repetitive push-pull tasks with light external load [PDF]
, 2015 Repetitive tasks in industrial works may contribute to health problems among operators, such as musculo-skeletal disorders, in part due to insufficient control of muscle fatigue.

Non-Existence of Stabilizing Policies for the Critical Push-Pull Network and Generalizations [PDF]
, 2013 The push-pull queueing network is a simple example in which servers either serve jobs or generate new arrivals. It was previously conjectured that there is no policy that makes the network positive recurrent (stable) in the critical case.

An inhibitory pull-push circuit in frontal cortex. [PDF]
, 2017 Push-pull is a canonical computation of excitatory cortical circuits. By contrast, we identify a pull-push inhibitory circuit in frontal cortex that originates in vasoactive intestinal polypeptide (VIP)-expressing interneurons.

EEG Measurement for Suppression in Refractive Amblyopia and Push-Pull Perception Efficacy
IEEE Transactions on Neural Systems and Rehabilitation Engineering, 2022 In order to evaluate refractive amblyopia suppression and understand the neural mechanism of amblyopia suppression and push-pull perception training, we recorded the EEG of refractive amblyopia children before, during, and after push-pull perception ...
