In (Béziau 2001), Béziau provides a means by which Gentzen’s sequent calculus can be combined with the general semantic theory of bivaluations. In doing so, according to Béziau, it is possible to construe the abstract ‘‘core’’ of logics in general, where logical syntax and semantics are ‘‘two sides of the same coin’’. The central suggestion there is that, by way of a modification of the notion ...

While modern cosmology, founded in the language of general relativity, is almost a century old, the meaning of the expansion of space is still being debated. In this paper, the question of radar ranging in an expanding universe is examined, focusing upon light travel times during the ranging; it has recently been claimed that this proves that space physically expands. We generalize the problem ...

The 71st Cold Spring Harbor Symposium on Quantitative Biology celebrated the numerous and expanding roles of regulatory RNAs in systems ranging from bacteria to mammals. It was clearly evident that noncoding RNAs are undergoing a renaissance, with reports of their involvement in nearly every cellular process. Previously known classes of longer noncoding RNAs were shown to function by every poss...

We extend our analysis for scalar fields in a Robertson-Walker metric to the electromagnetic field and Dirac fields by the method of invariants. The issue of the relation between conformal properties and particle production is re-examined and it is verified that the electromagnetic and massless spinor actions are conformal invariant, while the massless conformally coupled scalar field is not. F...

I n this issue of the Journal, Parashar et al. (1) present a single-center 10-year retrospective analysis characterizing patients undergoing coronary angiography after perioperative myocardial infarction (MI). The authors present an analysis of angiograms from 1,093 patients with perioperative MI anddescribe the high risk nature of associated percutaneous coronary intervention (PCI). The death ...

The cosmological many-body problem is effectively an infinite system of gravitationally interacting masses in an expanding universe. Despite the interactions’ long-range nature, an analytical theory of statistical mechanics describes the spatial and velocity distribution functions which arise in the quasi-equilibrium conditions that apply to many cosmologies. Consequences of this theory agree w...

All “relativities”—whether Galileian, Machian, or Einsteinian—are ruled out on both principle and on observational grounds, irrespective of scale. From atoms up to galaxies, matter prefers to rotate, rather than expand. A slightly amended Newtonian gravitation theory, obeying the Third Principle, is able to account for the observed facts. Electromagnetic waves propagate (isotropically) in the f...

Spironolactone has been marketed for over half a century as a 'potassium-sparing diuretic', used primarily in patients with ascites. With the realization that primary aldosteronism is the most common (5-13%) form of secondary hypertension, it has become widely used as a mineralocorticoid receptor antagonist. More recently, in the wake of the RALES trial, spironolactone in addition to standard t...

We study the tensorial modes of the two-fluid model, where one of this fluids has an equation of state p = −ρ/3 (variable cosmological constant, cosmic string fluid, texture) or p = −ρ (cosmological constant), while the other fluid is an ordinary matter (radiation, stiff matter, incoherent matter). In the first case, it is possible to have a closed Universe whose dynamics can be that of an open...
