In recent years, numerous groups of investigators have reported primary aldosteronism (PAL) to be much more common than previously thought.1–4 This has followed recognition of the aldosterone/renin ratio (ARR) as an improved, more sensitive method of screening for PAL and the application of ARR testing to a wider population, to include normokalemic, as well as hypokalemic, hypertensive subjects...

Mini-Monograph series this year, instead publishing more Review articles on topics that might once have been covered by Mini-Monographs. Here, we explain that decision and give some historical perspective on the Mini-Monographs. EHP was begun in 1972 by David P. Rall, then director of the NIEHS. In addition to publishing original research articles, the journal was intended as a means of publish...

Figure 1. Key performance indicators for Advanced Science during the first years. Table 1 presents the highest cited papers in 2016 (published in 2014 and 2015) which will be the main driving force for the next ISI impact factor. Popular topics include solar cells, batteries, but also photocatalysts, metal-organic frameworks, and hydrogel composites. Since the journal was included in PubMedCent...

ACTA is a comprehensive transaction framework that permits a transaction modeler to specify the e ects of extended transactions on each other and on objects in the database. ACTA allows the speci cation of (1) the interactions between transactions in terms of relationships between signi cant (transaction management) events, such as begin, commit, abort, delegate, split, and join, pertaining to ...

Scale is a physical attribute of a signal which occurs in many natural settings. Time-frequency distributions (TFDs) belonging to Cohen’s class are invariant to time and frequency shifts, but are not necessarily covariant to the time scalings of the signal. Conditions on the time-frequency kernel for yielding a scale covariant distribution have been previously derived (Cohen, 1995) . In this pa...

Consider s + 1 univariate normal populations with common variance σ2 and means μi, i = 0, 1, . . . , s, constrained by the tree-order restrictions μ0 ≤ μi, i = 1, 2, . . . , s. For certain sequences μ0, μ1, . . . the maximum likelihood-based estimator (MLBE) of μ0 diverges to −∞ as s → ∞ and its bias is unbounded. By contrast, the bias of an alternative estimator of μ0 proposed by Cohen and Sac...
