As part of our efforts in establishing biij as one of the important open-access journals dealing with topics relating to radiology, biomedical imaging and biomedical intervention, we have tirelessly pursued the indexing of biij in various relevant scientific indices and databases. For this reason, biij has been a member of CrossRef and has been made searchable by the Google Scholar search engin...

T he publication in this issue of Circulation of the Evaluation of the HeartWare Left Ventricular Assist Device for the Treatment of Advanced Heart Failure (ADVANCE) trial by Aaronson, Slaughter, and colleagues 1 tracks continuing advance in the rapidly expanding field of mechanical circulatory support. As implantable device technology and the clinical learning curve have supported better outco...

Cross-validation has long been used for choosing tuning parameters and other model selection tasks. It generally performs well provided the data are independent, or nearly so. Improvements have been suggested which address ordinary cross-validation’s (OCV) shortcomings in correlated data. Whereas these techniques have merit, they can still lead to poor model selection in correlated data or are ...

Isotropization occurs on time scales much shorter than the thermal equilibration time. This is a crucial ingredient for the understanding of collision experiments of heavy nuclei or other nonequilibrium phenomena in complex many body systems. We discuss in detail the limitations of estimates based on standard “linear” or relaxationtime approximations, where isotropization and thermal equilibrat...

Far-field optical lens resolution is fundamentally limited by diffraction, which typically is about half of the wavelength. This is due to the evanescent waves carrying small scale information from an object that fades away in the far field. A recently proposed superlens theory offers a new approach by surface excitation at the negative index medium. We introduce a far-field optical superlens (...

The article by Goldberg and colleagues found in this issue is a meticulous history of the changes in incidence and in-hospital and long term case fatality rates of myocardial infarction (MI) for a defined New England community from 1975 to 1995 (1). The authors suggest that there is a decline in the incidence of acute MI as well as in the short term and one-year mortality in survivors postdisch...

Starting from innovative distance labs in embedded systems courses with hardware-in-the-loop, this paper focuses on the surrounding environment necessary to efficiently hold courses in distance education. After a short overview of administration issues, we discuss ways to retain personal contacts vital to learning in distance lab setups. We present replacements for class lectures & supervised l...

Speed and Mannion make a good case that the rise of populism poses significant challenges for health policy. This commentary suggests that the link between populism and health policy should be further nuanced in four ways. First, a deconstruction of the term populism itself and a focus on the far right dimension of populist politics; second, a focus on the supply side and more specifically the ...

Let n1 and n2 be the indexes of refraction of two homogeneous and isotropic media I and II, respectively. Suppose that from a point O inside medium I light emanates with intensity f (x) for x ∈ Ω . We want to construct a refracting surface R parameterized as R = {ρ(x)x : x ∈ Ω}, separating media I and II, and such that all rays refracted by R into medium II have directions in Ω∗ and the prescri...

Sir, ‘References’ in an article includes the list of articles, books or the communications that have been referred to/consulted in presenting the document. They provide the source of the information being quoted in the article. The International Committee of Medical Journal Editors (ICMJE) has created the Uniform Requirements, primarily to help authors and editors in their mutual task of creati...
