OBJECTIVE To assess the role of Intervention Mapping (IM) in designing disease prevention interventions worldwide. METHODS Systematic search and review of the relevant literature-peer-reviewed and grey-was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. FINDINGS Only five of the twenty two included studies reviewed were RCTs that c...

Abstract. Let 1 = z1 ≥ |z2| ≥ · · · ≥ |zn| be n complex numbers, and consider the power sums sν = z1 + z2 + · · · + zn , 1 ≤ ν ≤ n. Put Rn = min max1≤ν≤n |sν |, where the minimum is over all possible complex numbers satisfying the above. Turán conjectured that Rn > A, for A some positive absolute constant. Atkinson proved this conjecture by showing Rn > 1/6. It is now known that 1/2 < Rn < 1, f...

E. Thorp introduced the following card shuffling model. Suppose the number of cards n is even. Cut the deck into two equal piles. Drop the first card from the left pile or from the right pile according to the outcome of a fair coin flip. Then drop from the other pile. Continue this way until both piles are empty. We show that if n is a power of 2 then the mixing time of the Thorp shuffle is O(l...

We show that hard electroproduction is a promising way to study exotic hybrid mesons, in particular through the hybrid decay channel H → πη. We discuss the πη generalized distribution amplitude, calculate the production amplitude and propose a forward-backward asymmetry as a signal for the hybrid meson production.

This paper presents a complete overview of power frequencyoscillations in power system and the root causes of their generation and how they can be damped. Various methods are been presented to tackle with these oscillations can be damped efficiently and the importance of selection of stabilizing input signal for FACTS devices to damp oscillations and how they can be choosen .

We provide a combinatorial approach to the largest power of p in the number of permutations π with π = 1, for a fixed prime number p. With this approach, we find the largest power of 2 in the number of involutions, in the signed sum of involutions and in the numbers of even or odd involutions.

Under Martin’s Maximum every σ-ideal on ω1 is a subset of an ideal Rudin-Keisler reducible to a finite Fubini power of the nonstationary ideal restricted to a positive set.

We characterize the equilibrium states for the two-phase Stefan problem with surface tension and with or without kinetic undercooling, and we analyze their stability in dependence of physical and geometric quantities.

where d is a positive integer, 0≤ i< d and r0,r1, . . .rd−1 are rational numbers, such that the famous 3x+1 conjecture holds if and only if the R-orbit of 2n contains 2 for all positive integers n. We then show that the R-orbit of an arbitrary positive integer is a constant multiple of an orbit that contains a power of 2. Finally we apply our main result to show that any cycle {x0, . . . ,xm−1}...
