In this letter, we report the single-molecule conductance properties of a cyano-functionalized perylene-diimide derivative (PDI8-CN2) investigated with gold nano-electrodes. This molecule is of large interest for the fabrication of high-performance and air-stable n-type organic field-effect transistors. Low-bias experiments performed on mechanically controllable break junctions reveal the prese...

A conjecture of V. Sós [3] is proved that any set of 34 (n 3 ) + cn2 triples from an n-set, where c is a suitable absolute constant, must contain a copy of the Fano configuration (the projective plane of order two). This is an asymptotically sharp estimate. Given a 3-uniform hypergraph F , let ex3(n,F) denote the maximum possible size of a 3-uniform hypergraph of order n that does not contain a...

Let {Eσ(N)}σ∈ΣN be a family of |ΣN | = 2N centered unit Gaussian random variables defined by the covariance matrix CN of elements cN (σ, τ) := Av (Eσ(N)Eτ (N)), and HN (σ) = − √ NEσ(N) the corresponding random Hamiltonian. Then the quenched thermodynamical limit exists if, for every decomposition N = N1 + N2, and all pairs (σ, τ) ∈ ΣN × ΣN : cN (σ, τ) ≤ N1 N cN1(π1(σ), π1(τ)) + N2 N cN2(π2(σ), ...

In this paper we present an approach for personalizing gamification to the needs of each individual person. We designed the personalization for computer-supported collaborative learning environments by synthesizing three existing design frameworks: the lens of intrinsic skill atoms, gamification user type hexad and heuristics for effective design of gamification. The result of the design proces...

Traffic prediction systems can play an essential role in intelligent transportation systems (ITS). Prediction and patterns comprehensibility of traffic characteristic parameters such as average speed, flow, and travel time could be beneficiary both in advanced traveler information systems (ATIS) and in ITS traffic control systems. However, due to their complex nonlinear patterns, these systems ...

Thorium redox chemistry is extremely scarce due to the high stability of ThIV. Here we report two unique examples thorium arenide complexes prepared by reduction a ThIV-siloxide complex in presence naphthalene, mononuclear [K(OSi(OtBu)3)3Th(η6-C10H8)] (1) and inverse-sandwich [K(OSi(OtBu)3)3Th]2(μ-η6,η6-C10H8)] (2). The electrons stored these allow broad range substrates (N2O, AdN3, CO2, HBBN)....
