To the Editor: Since 2003, highly pathogenic avian influenza (HPAI) H5N1 has shaken the world. In 10 countries, 258 confirmed cases in humans and 154 deaths have been reported (1). The number of countries with confirmed HPAI in poultry and wild birds jumps to 54 (2). Almost all persons infected with H5N1 have had close contact with sick or dead poultry by having butchered them, plucked them, or...

This paper presents an advanced dynamic voltage restorer with integrated energy optimal compensation (EOC-DVR), which combines the advantages of pre-sag and minimization compensation. The performance parameters EOC-DVR, such as compensatory capability, loss energy, duration compensation, can be balanced by this strategy. Additionally, impact on load is further reduced proposed method. By analyz...

In Alzheimer's disease (AD), there is a significant loss of locus ceruleus (LC) noradrenergic neurons. However, functional and anatomical evidence indicates that the remaining noradrenergic neurons may be compensating for the loss. Because the noradrenergic system plays an important role in learning and memory, it is important to determine whether compensation occurs in noradrenergic neurons in...

David V. Anderson, Richard W. Harris, and Douglas M. Chabries Brigham Young University, Provo, Utah ABSTRACT A new hearing compensation algorithm based on a homomorphic multiplicative AGC (automatic gain control) is evaluated and compared against commercially available digitally programmable analog hearing aids. Both quantitative (speech recognition and threshold) and qualitative tests were use...

The cultures in the Papua New Guinea Highlands are characterised by a tradition of retribution. Compensation is part of an elaborate system of exchanging gifts, goods and services. Compensation is paid to those who have suffered some kind of loss for which others are held responsible. Such incidents include death or injury caused by fighting, a road accident or domestic violence, theft, rape, g...

The way in which the number and size of cells in an organ are determined poses a central challenge in our understanding of organ size control. Compensation is an unresolved phenomenon, whereby a decrease in cell proliferation below some threshold level triggers enhanced postmitotic cell expansion in leaf primordia. It suggests an interaction between these cellular processes during organogenesis...

Hearing loss is a significant and unfortunately common occupational malady. Over the past several decades both the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH) have initiated efforts to better understand and to limit the occurrence of occupational hearing loss, particularly as it relates to excessive noise exposure. T...

PURPOSE In this study we examined psychosocial adaptation to vision loss and its relationship to depressive symptomatology in legally blind older adults with age-related macular degeneration (ARMD). DESIGN AND METHODS The 144 study participants were outpatients of a large regional vision clinic that specializes in the diagnosis and treatment of ARMD in older adults. They were administered a b...

Dosage compensation is a specialized form of gene regulation that balances sex-chromosome linked gene expression between the sexes. In C. elegans, dosage compensation is achieved by the activity of the dosage compensation complex (DCC). The DCC binds along both X chromosomes in hermaphrodites to down-regulate gene expression by half, limiting X-linked gene products to levels produced in XO male...
