Over the last few decades many techniques have been developed for determination of Sr/Y in the environment. Čerenkov counting technique (developed in the 1960s) is widely used, but can be further developed by the application of emerging technologies. For example, it is believed that the application of the triple-to-double coincidence ratio (TDCR) liquid scintillation counting method can be used...

In this paper we analyze the steady-state bifurcations from the trivial solution of the reaction-diffusion equations associated to a model chemical reaction, the so-called Brusselator. The present analysis concentrates on the case when the first bifurcation is from a double eigenvalue. The dependence of the bifurcation diagrams on various parameters and perturbations is analyzed. The results of...

A connected n-chromatic graph G is double-critical if for all the edges xy of G, the graph G−x−y is (n−2)-chromatic. In 1966, Erdős and Lovász conjectured that the only double-critical n-chromatic graph is Kn. This conjecture remains unresolved for n ≥ 6. In this short note, we verify this conjecture for claw-free graphs G of chromatic number 6.

The present paper is devoted to the classification of irregular surfaces of general type with pg 1⁄4 q 1⁄4 2 and non-birational bicanonical map. The main result is that, if S is such a surface and if S is minimal with no pencil of curves of genus 2, then S is a double cover of a principally polarized abelian surface ðA;YÞ, with Y irreducible. The double cover S ! A is branched along a divisor B...

Single and double electromagnetically induced transparency (EIT) in a medium, consisting of fourlevel atoms in the inverted-Y configuration, are discussed using mechanical and electrical analogies. A three coupled spring-mass system subject to damping and driven by an external force is used to represent the four-level atom mechanically. The equations of motion of this system are solved analytic...

We observe that the main theorem in [4] immediately implies its analogue for closed 3–manifolds. Theorem 1. Suppose Y is a closed irreducible 3–manifold, F ⊂ Y is a closed connected surface of genus g ≥ 2. If HM•(Y |F ) ∼= Z, then Y fibers over the circle with F as a fiber. The case that g = 1 is already treated in [3], following the argument of Ghiggini [1]. Theorem 2. [3, Theorem 42.7.1] Supp...

BACKGROUND AND PURPOSE Neuropeptide Y (NPY) and its receptors have been implicated in the control of emotional-affective processing, but the mechanism is unclear. While it is increasingly evident that stimulation of Y₁ and inhibition of Y₂ receptors produce prominent anxiolytic and antidepressant effects, the contribution of the individual NPY receptor subtypes in the acquisition and extinction...
