Fault management is a crucial part of cellular network management systems. The status of the base stations is usually monitored by well-defined key performance indicators (KPIs). The approaches for cell degradation detection are based on either intra-cell or inter-cell analysis of the KPIs. In intra-cell analysis, KPI profiles are built based on their local history data whereas in inter-cell an...

A significant proportion of neurons in the brain undergo programmed cell death. In order to prevent the diffusion of damaging degradation products, dying neurons are quickly digested by microglia. Despite the importance of microglia in several neuronal pathologies, the mechanism underlying their degradation of neurons remains elusive. Here, we exploit a microglial population in the zebrafish to...

Reliability of prognostics and health management systems (PHM) relies upon accurate understanding of critical components’ degradation process to predict the remaining useful life (RUL). Traditionally, degradation process is represented in the form of data or expert models. Such models require extensive experimentation and verification that are not always feasible. Another approach that builds u...

[1] Molecular level characterizations of dissolved lignin were conducted in Mississippi River plume waters to study the impact of various removal mechanisms (photooxidation, microbial degradation, and flocculation) on dissolved organic material (DOM) concentrations and compositions. Prior to analysis, dissolved (<0.2-mm pore size) samples were size fractionated by ultrafiltration into high mole...

Building on prior research that marital functioning is associated with a variety of health outcomes, we evaluated the association between marital adjustment and a marker of inflammation in a sample of married adults between the ages of 35 and 84 years old (N 415) from the second wave of the population-based Survey of Midlife Development in the United States (MIDUS II). Specifically, we evaluate...

The role climate change may play in altering human health, particularly in the emergence and spread of diseases, is an evolving area of research. It is important to understand this relationship because it will compound the already significant burden of diseases on national economies and public health. Authorities need to be able to assess, anticipate, and monitor human health vulnerability to c...

BACKGROUND . Subjective social status (SSS) is associated with physical and mental health in diverse samples. However, community, cultural, and ethnic influences on SSS are poorly understood, especially among rural and American Indian populations. OBJECTIVE We aimed to examine similarities and differences in how community poverty, family context, and life course attainment predict SSS among C...
