The purpose of this study was to characterize both spatial and temporal patterns of the shoulder joint movement in the upper limb motion when ballet dancers are performing the flaps of swan wings. Twenty-three expert female dancers (Dance group) and 21 inexperienced age-matched females (Control group) participated in the study. Thirty-three reflective markers were attached to the trunk and uppe...

Commercialization of wave energy will lead to the necessary deployment of Wave Energy Converters (WECs) in arrays, or wave farms. In order for projects in the United States to be approved, regulatory agencies must perform an Environmental Assessment proving little to no environmental impact. However, little is known about the environmental impacts of such wave farms. As a result, the environmen...

Recurrent ventricular arrhythmia can be fatal and cause serious complications, particularly when it is caused immediately after an operation. Incorrect placement of a Swan-Ganz catheter can trigger life-threatening ventricular arrhythmia, but even intensive care specialists tend to miss this fact. Here, we report a case of recurrent ventricular arrhythmia causing a severe hemodynamic compromise...

The Paper of the Year Award was established in 2008 by Environmental Health Perspectives (EHP) as a means of reinforcing high-quality articles published in the journal, identifying emerging research themes, and tracking the impact of groundbreaking research (Tilson 2008). In this issue, we are pleased to announce that the EHP Paper of the Year for 2009 is “Decrease in Anogenital Distance among ...

A bad wound will heal but a bad name will kill. —Scottish proverb Schizophrenia is a word that frightens people, is replete with stigma, is used pejoratively in daily speech and is ety-mologically absurd. There is now widespread international interest in In this Editorial, we examine the justification for giving up the term and consider strategies for finding an alternative. In a recent article...

For purposes of implementing field arithmetic in F2n efficiently, it is desirable to have an irreducible polynomial f(x) ∈ F2[x] of degree n with as few terms as possible. The number of terms must be odd, as otherwise x+1 would be a factor. Often a trinomial x+x+1 can be found, or at least a pentanomial, x+x1 +x2 +x3 +1, where n > m1 > m2 > m3 > 0. If α is a root of f , then {1, α, α, . . . , α...
