A mathematical model of orientation selectivity in a single hypercolumn of the primary visual cortex developed in a previous work [Ursino, M., & La Cara, G.-E. (2004). Comparison of different models of orientation selectivity based on distinct intracortical inhibition rules. Vision Research, 44, 1641-1658] was used to analyze the possible mechanisms underlying tilt aftereffect (TAE). Two altern...

this paper reviews the current literature examining the pervasive symptom of fatigue experienced in three of the most common degenerative neurological conditions: multiple sclerosis (ms), parkinson’s disease (pd) and post-polio syndrome (pps). the existing literature can be considered under four headings definition and prevalence, type, cause, impact of fatigue. fatigue is a common symptom in d...

UNLABELLED Multiple sclerosis (MS) prevalence is higher in geographic regions with less sunlight exposure. Melatonin participates in the effects of sunlight in healthy individuals and could play a role in MS pathophysiology. Melatonin crosses the blood-brain barrier and exerts antioxidative, immunomodulatory, and anti-inflammatory effects. Chronic fatigue syndrome concerns 80 - 90% MS patients....

The soybean hawkmoth, known as Clanis bilineata tsingtauica (CBT), is a traditional edible insect of East Asia. CBT larvae are an ideal nutrient source containing 18 amino acids and 19 fatty acids. total essential acid contents could meet the requirement preschool children adults. Long chain content, especially linolenic quite high than egg or soybean. Various active components, such oil, polys...

Abstract Self-loosening of bolted joints can occur in a vibration environment, and it may induce bolt fatigue fracture with catastrophic consequences. It is essential to clarify the self-loosening mechanism, based on which novel anti-loosening thread structures be developed. In this paper, we propose concept radial slippage propagation provide new insights into process. The theory states that a...

this paper presents a finite element analysis and its related experimental test of corrugated steel web beams subjected to fatigue loading. a particular focus in this study was set on the fatigue failure arising from the web-to-flange welded joint of the corrugated steel web beam. a detailed three-dimensional finite element model which explicitly includes the geometry of the web-to-flange welds...
