International Journal of Cancer, EarlyView.What's New? Anal and vulvar high‐grade squamous intraepithelial lesions (HSILs) frequently recur following treatment. Additional genital and anal procedures, however, can be distressing for patients and are potentially disfiguring. This trial assessed whether the 9‐valent human papillomavirus (9vHPV) vaccine reduces HSIL recurrence risk or HPV ...

Oikos, EarlyView.Grasslands, by definition, are dominated by graminoids. Nevertheless, forbs also make up a substantial part of vascular plant diversity in grasslands and are important resources of mammalian herbivores. However, forb recruitment is constrained by successful dominant graminoids, limiting access to safe sites for germination.

steel research international, EarlyView.Laser welding of duplex stainless steel disrupts phase balance, promotes nitride precipitation, and reduces fatigue resistance. Postweld heat treatment restores austenite and dissolves nitrides, but the resulting crystallography and phase morphology still impair fatigue performance.

Tight Upper and Lower Bounds to the Information Rate of the Phase Noise Channel
, 2013 Numerical upper and lower bounds to the information rate transferred through the additive white Gaussian noise channel affected by discrete-time multiplicative autoregressive moving-average (ARMA) phase noise are proposed in the paper. The state space of
