Vulnerability and resilience to Alzheimer’s disease: early life conditions modulate neuropathology and determine cognitive reserve

open access: yesAlzheimer’s Research & Therapy, 2018
Background Alzheimer’s disease (AD) is a progressive neurodegenerative disorder with a high prevalence among the elderly and a huge personal and societal impact.

Learning arbitrary functions with spike-timing dependent plasticity learning rule [PDF]

open access: yes, 2005
A neural network model based on spike-timing-dependent plasticity (STOP) learning rule, where afferent neurons will excite both the target neuron and interneurons that in turn project to the target neuron, is applied to the tasks of learning AND and XOR ...

Neurochemical changes in basal ganglia affect time perception in parkinsonians

open access: yesJournal of Biomedical Science, 2018
Background Parkinson’s disease is described as resulting from dopaminergic cells progressive degeneration, specifically in the substantia nigra pars compacta that influence the voluntary movements control, decision making and time perception.

Uncoupled material model of ductile fracture with directional plasticity [PDF]

open access: yes, 2017
Proposed paper deals with the application of plastic response with directional distortional hardening (DDH) in uncoupled ductile fracture model and comparison of the results with the same ductile fracture model based on isotropic J2 plasticity.

Processing of Plastics [PDF]

open access: yesEnvironmental Health Perspectives, 1975
An overview is given of the processing of plastic materials from the handling of polymers in the pellet and powder form to manufacturing of a plastic fabricated product. Various types of equipment used and melt processing ranges of various polymer formulations to make the myriad of plastic products that are commercially available are discussed.

Molecular mechanisms that stabilize short term synaptic plasticity during presynaptic homeostatic plasticity. [PDF]

open access: yes, 2018
Presynaptic homeostatic plasticity (PHP) compensates for impaired postsynaptic neurotransmitter receptor function through a rapid, persistent adjustment of neurotransmitter release, an effect that can exceed 200%.

Functional partitioning of sentence processing and emotional prosody in the right perisylvian cortex after perinatal stroke

open access: yesScientific Reports
In healthy adults different language abilities—sentence processing versus emotional prosody—are supported by the left (LH) versus the right hemisphere (RH), respectively.
