In the mass region around A = 190 about 70 superdeformed (SD) rotational bands are known in 25 different nuclei [1]. In many cases several bands have been found which are built on excited states in the SD potential energy minimum. The nature of these excitations has been the subject of experimental and theoretical investigations in recent years. In the odd-even and odd-odd nuclei it seems clear...

We consider the third-order nonlocal boundary value problem u ′′′ (t) = f (t, u(t)), a.e. in (0, 1), u(0) = 0, u ′ (ρ) = 0, u ′′ (1) = λ[u ′′ ], where 0 < ρ < 1, the nonlinear term f satisfies Carathéodory conditions with respect to L 1 [0, T ], λ[v] = 1 0 v(t) dΛ(t), and the functional λ satisfies the resonance condition λ[1] = 1. The existence of a solution is established via Mawhin's coincid...

Finding that an association is statistically insignificant in a clinical trial has two distinct explanations. (1) The association may be real, but the sample size is too small to distinguish the results from those due to chance. (2) The association is spurious – a coincidence due to chance. Based on Weisberg (2011), this paper argues that there is a third explanation: the association may be rea...

The photodissociation dynamics of bare I 2 and I 2 Ar at 413 and 390 nm have been investigated using a fast beam instrument coupled with a new photofragment coincidence imaging detector. Results from the application of this technique to the dissociation of I 2 and I 2 Ar yielded the dissociation energy of I 2 (D0ðI 2 Þ 1⁄4 1:012 0:008 eV) and I 2 –Ar binding energy (D0ðI 2 –ArÞ 1⁄4 45 8 meV). T...

In this work a measurement of the muon intensity at the Waste Isolation Pilot Plant (WIPP) near Carlsbad, NM, USA is presented. WIPP is a salt mine with a depth of 655 m. The vertical muon flux was measured with a two panels scintillator coincidence setup to Φvert = (3.10 +0.05 −0.07) 10 −7 s−1cm−2sr−1.

This review deals with applications of activation analysis to geological samples : , minerals and rocks . The various activation sources suitable for tb.is purpose are discussed. Applications using isotopic neutron sources are reviewed in some detail , those using neutron generators are discussed on a rrore general basis . Present trends in instrumental neutron-activation techniques are briefly...

Second order lower bounds for the entropy function expressed in terms of the index of coincidence are derived. Equivalently, these bounds involve entropy and Rényi entropy of order 2. The constants found either explicitly or implicitly are best possible in a natural sense. The inequalities developed originated with certain problems in universal prediction and coding which are briefly discussed.

One hundred years ago this Sunday, on November th, , Bertrand Russell delivered the Inaugural Address to the Aristotelian Society’s thirty-fourth session – it was Russell’s second year as President. His lecture was entitled ‘On the Notion of Cause’, and as the Proceedings here note, a discussion followed in which a number of members took part. Outside the Aristotelian Society, the discussion co...

Since the introduction of inflation targeting, inflation expectations have become firmly anchored at target and there has been a flattening of the Phillips curve. These changes mean that a “divine coincidence” between headline inflation and output-gap stabilization is less apparent than when inflation targeting was introduced. This has led some to call for a fundamental reengineering of inflati...

We prove common fixed point theorems for two pairs of hybrid mappings satisfying implicit relations in complete metric spaces using the concept of R−weak commutativity of type AT and we correct errors of [1], [3] and [8]. Our theorems generalize results of [1-3], [8], [12-16] and [21].
