We present a new strategy for gap estimation in randomized algorithms for multiarmed bandits and combine it with the EXP3++ algorithm of Seldin and Slivkins (2014). In the stochastic regime the strategy reduces dependence of regret on a time horizon from (ln t) to (ln t) and eliminates an additive factor of order ∆e 2 , where ∆ is the minimal gap of a problem instance. In the adversarial regime...

0 = λ1 ≤ λ2 ≤ · · · ≤ λn ≤ 2. Interested in λ2, known as the spectral gap. • λ2 = 0 iff G is disconnected • 1/λ2 is the relaxation time of the simple RW on G Conjecture (Fan Chung, 2014). A constant fraction of edges of G(n, p) are such that their removal increases the spectral gap. Adding an edge to random graphs For a graph G = (V,E), let a−(G) := fraction of nonedges in G whose addition decr...

A new tellurophene-based π-conjugated polymer, PDTDPPTe, was synthesized. PDTDPPTe exhibits a smaller optical band gap (E(g)(opt) = 1.25 eV) than thiophene-based PDTDPPT (E(g)(opt) = 1.30 eV). Thin-film transistors comprising PDTDPPTe displayed outstanding performance (μ(max) = 1.78 cm(2) V(-1) s(-1), I(on)/I(off) = 10(5-6)).

The mechanism of dynamical mass generation for the gauge field is studied through 1-loop. We find out that torsion is an obstruction to the appearance of a 1-loop mass correction. Contrary, if torsion is not present, a mass gap is generated for the 2-form field. E-mail: [email protected] E-mail: [email protected]

Looking at recent developments in private e-procurement, automating processes is increasingly based on standard product classification schemes such as eCl@ss and UNSPSC. However, this trend is yet not reflected in public e-procurement to the same degree. This paper provides arguments for the existing gap concerning product classification and semantic interoperability. It compares the contributi...

In the color-flavor-locked (CFL) phase of the QCD superconductor we show that baryons behave as qualitons (called “superqualitons”) with quantum numbers B = (1 mod 2)/3, S = 1/2 and Y = B. Bound superqualitons may cause the superconducting gap in the CFL phase to be effectively nonexistent, a novel phenomenon not seen in conventional superconductors. E-mail: [email protected] E-mail:...
