To assess geographic distributions of elements in the Arctic we compared essential and non-essential elements in the livers of polar bears (Ursus maritimus) collected from five regions within Canada in 2002, in Alaska between 1994 and 1999 and from the northwest and eas...

Men sometimes withdraw support for gender equality movements when their higher gender status is threatened. Here, we expand the focus of this phenomenon by examining it cross-culturally, to test if both individual- and country-level variables predict men's collective ac...

Summary Objectives Haemophilus influenzae is an important cause of invasive infection but contemporary data in non-selected populations is limited. Methods Population-based surveillance for Haemophilus influenzae bacteremia was conducted in seven regions in Australia, C...

OBJECTIVES: This study prospectively investigated the impact of integration of a multidetector computed tomography (MDCT) annular area sizing algorithm on transcatheter aortic valve replacement (TAVR) outcomes. BACKGROUND: Appreciation of the 3-dimensional, noncircular ...

In the present study, we explored the real-world efficacy of the immuno-oncology checkpoint inhibitor nivolumab and the tyrosine kinase inhibitor cabozantinib in the second-line setting. Using the International Metastatic Renal Cell Carcinoma Database Consortium (imdc) ...

The spectral pattern of light attenuation in the ultraviolet (UV) and blue region (360‐500 nm) was analyzed for seven high Arctic lakes. The best description of Kd versus wavelength was obtained with an exponential model similar to the model used for absorption by chrom...

Abstract Environmental heterogeneity across the landscape can cause lineage divergence and speciation. The Geonoma macrostachys (Arecaceae) species complex has been proposed as a candidate case of ecological speciation in Amazonia due to evidence of habitat partitioning...

ABSTRACT A growing collection of mtDNA genetic information from waterfowl species across North America suggests that larger-bodied cavity-nesting species exhibit greater levels of population differentiation than smaller-bodied congeners. Although little is known about n...

Abstract Five methods are described for reducing or eliminating the error oscillations resulting from the application of the Peaceman–Rachford alternating direction implicit algorithm to disk electrode simulation problems involving an initial discontinuity, such as resu...
