A family of soluble, reduced iron-sulfur clusters with nuclearities 4, 8, and 16 having tertiary phosphine ligation and based on the Fe(4)S(4) cubane-type structural motif has been synthesized. The results of this investigation substantially extend and improve the results of our original work on iron-sulfur-phosphine clusters (Goh, C.; Segal, B. M.; Huang, J.; Long, J. R.; Holm, R. H. J. Am. Ch...

This note describes some additional information that complements the main BayesAct-S model described in [2] 1 Comparing Situational and Fundamental Self Sentiments In the paper we use the following function to measure inauthenticity: ia(s) = ln ( Pr(ss) Pr(sf ) ) (1) However, the original statement of the theory in [1] hypothesises that inauthenticity is a difference, from which we derived that...

The purpose of the present study was to determine whether a protein-rich beverage leads to a differential response in appetite, satiety and subsequent energy intake compared with an energy- and macronutrient-matched solid version in young people. A total of fifteen adolescents (eight girls and seven boys; age 14 (SEM 1) years, BMI percentile 79 (SEM 4) %) randomly completed two testing days tha...

To examine how small structural changes influence the reactivity and magnetic properties of biologically relevant metal complexes, the reactivity and magnetic properties of two structurally related five-coordinate Fe(III) thiolate compounds are compared. (Et,Pr)-ligated [Fe(III)(S(2)(Me2)N(3)(Et,Pr))]PF(6) (3) is synthesized via the abstraction of a sulfur from alkyl persulfide ligated [Fe(III)...

We propose that self-organiza tion may provide a mechanism by which power-law cluster distributions of mob ile pr ey (i.e. , fish , phytoplankton ) may develop ; in cont rast , such dist ributi ons have ofte n bee n at t ributed to scaling of the background environment. Evi dence support ing our proposal is provided by examining the dynamics of a cellular automato n-like model of a pr edator-pr...

Let pr,s(n) denote the number of partitions of a positive integer n into parts containing no multiples of r or s, where r > 1 and s > 1 are square-free, relatively prime integers. We use classical methods to derive a Hardy-Ramanujan-Rademacher-type infinite series for pr,s(n).
