This article explores Andrei Tarkovskii’s conception of truth in Solaris (1972) and Stalker (1979) as part of his wider philosophical project concerning knowledge. The director’s epistemological views form a core dimension of his life and aesthetic as he strives towards what he considers a higher, spiritual ‘idea of knowing’. In his search for this idealised notion of truth, Tarkovskii uses the...

In 2005 major progress was achieved in further evaluation of the detailed ion-optical and technical design of the individual accelerator systems of the FAIR complex. The according descriptions were summarized within two versions of Technical reports (TR) [1]. In addition a cost book for the accelerator system was created, that describes the costs of the individual systems within a ‘buttom-up’ c...

It is well known that for a regular stable potential of pair interaction and a small value of activity one can define the corresponding Gibbs field (a measure on the space of configurations of points in R). In this paper we consider a converse problem. Namely, we show that for a sufficiently small constant ρ1 and a sufficiently small function ρ2(x), x ∈ R , that is equal to zero in a neighborho...

The demand for ever-increasing density of information storage and speed of manipulation boosts an intense search for new magnetic materials and novel ways of controlling the magnetic bit. Here, we report the synthesis of a ferromagnetic photovoltaic CH3NH3(Mn:Pb)I3 material in which the photo-excited electrons rapidly melt the local magnetic order through the Ruderman-Kittel-Kasuya-Yosida inter...

where Ω is an open and bounded domain with smooth boundary, ∇̂u denotes the strain tensor, ∇̂u := 12 (∇u + (∇u)T ), ψ ∈ H(∂Ω) is the boundary displacement or source, and C ∈ L(Ω) denotes the isotropic elasticity tensor with Lamé parameters λ, μ: C = λI3 ⊗ I3 + 2μIsym, a.e. in Ω, where I3 is 3 × 3 identity matrix and Isym is the fourth order tensor such that IsymA = Â, ρ ∈ L(Ω) is the density, and...

Cyclometalated ruthenium sensitizers have been synthesized that differ with number of thiophene units on the auxiliary ligands. Sensitizers possessing four (SA25, SA246, and SA285) or none (SA282) sulfur atoms in their structures, were tested in solar cell devices employing I3-/I- redox mediator, enabling an estimation of the influence of sulfur-iodine/iodide interactions on dye-sensitized sola...

A stack is a last-in first-out sorting device with push and pop operations. Knuth [7] showed that a permutation π can be sorted (meaning that by applying push and pop operations to the sequence of entries π(1), . . . , π(n) we can output the sequence 1, . . . , n) if and only if π avoids the permutation 231, i.e., if and only if there do not exist three indices 1 ≤ i1 < i2 < i3 ≤ n such that π(...

The reaction dynamics of ground state boron atoms, B(Pj), with acetylene, was reinvestigated and combined with novel electronic structure calculations. Our study suggests that the boron atom adds to the carbon–carbon triple bond of the acetylene molecule to yield initially a cyclic intermediate undergoing two successive hydrogen atom migrations to form ultimately an intermediate i3. The latter ...

The influence of a small change of carrier number on the superconducting transition temperature Tc in the incommensurate organic superconductors is investigated for MDT-TSF I3 0.422 MDT-TSF: methylenedithiotetraselenafulvalene, Tc=4.9 K in comparison with MDT-TSF AuI2 0.436 Tc=4.5 K . Careful estimation of the degree of charge transfer by means of the Raman spectra as well as the Shubnikov–de H...
