Microstructural changes in CoCrFeMnNi under mild tribological load

Different Functional and Microstructural Changes Depending on Duration of Mild Cognitive Impairment in Parkinson Disease.

BACKGROUND AND PURPOSE The higher cortical burden of Lewy body and Alzheimer disease-type pathology has been reported to be associated with a faster onset of cognitive impairment of Parkinson disease. So far, there has been a few studies only about the changes of gray matter volume depending on duration of cognitive impairment in Parkinson disease. Therefore, our aim was to evaluate the differe...

A coupled fiber-matrix model demonstrates highly inhomogeneous microstructural interactions in soft tissues under tensile load.

A soft tissue's macroscopic behavior is largely determined by its microstructural components (often a collagen fiber network surrounded by a nonfibrillar matrix (NFM)). In the present study, a coupled fiber-matrix model was developed to fully quantify the internal stress field within such a tissue and to explore interactions between the collagen fiber network and nonfibrillar matrix (NFM). Voro...

Microstructural White Matter Changes, Not Hippocampal Atrophy, Detect Early Amnestic Mild Cognitive Impairment

BACKGROUND Alzheimer's disease (AD) is generally considered to be characterized by pathology in gray matter of the brain, but convergent evidence suggests that white matter degradation also plays a vital role in its pathogenesis. The evolution of white matter deterioration and its relationship with gray matter atrophy remains elusive in amnestic mild cognitive impairment (aMCI), a prodromal sta...

Balancing Load under Large and Fast Load Changes in Distributed Computing Systems - A Case Study

This paper discusses a load balancing technique for distributed processing systems in which the load may vary over a wide range and at a high rate. Each processor performs a source or server algorithm for migrating processes when its load crosses some assigned upper or lower bound; these bounds are dynamically adjusted. Taking into account the speed at which loads vary and the latency of the un...
