Interaction and functional specialization across a distributed neural circuit for flexible task control in macaques [PDF]

Nature Communications
Reversal tasks have been regarded as probes of behavioural inhibition and linked to prefrontal and specifically orbitofrontal cortex. The centrality of behavioural inhibition to reversal task performance and the task’s dependence on particular prefrontal

DGADiff: Decoupled Guide Attention with Diffusion Model for Portrait Stylization [PDF]

Sensors
Diffusion-based models have substantially propelled the progress of portrait stylization. Nevertheless, the lack of clear supervisory signals often leads to pattern drift in the target portrait.

Thermodynamics of climate change: generalized sensitivities [PDF]

Atmospheric Chemistry and Physics, 2010
Using a recent theoretical approach, we study how global warming impacts the thermodynamics of the climate system by performing experiments with a simplified yet Earth-like climate model.

Radiation Damage in the Structure of the CR-39 Nuclear Detector Material as A Result of the Alpha's Energy Loss [PDF]

مجلة جامعة الانبار للعلوم الصرفة, 2022
In this work, the damage caused by the passage of alpha particles inside the CR-39 nuclear detector material on its chemical structure was studied. All samples at room temperature using a 241Am-Be neutron source with a flux of 5^10 neutrons.cm-2.s-1 ...

High-Energy Heavy Ion Tracks in Nanocrystalline Silicon Nitride

Crystals, 2022
At present, silicon nitride is the only nitride ceramic in which latent ion tracks resulting from swift heavy ion irradiation have been observed. Data related to the effects of SHIs on the nanocrystalline form of Si3N4 are sparse.
