TL;DR: In this paper, the authors numerically study complex dual-interface grating systems to enhance absorption efficiency in thin-film silicon solar cells and show that the distinctly different nature of the gratings can provide complementary enhancement mechanisms, which further exploit by tailoring the specific periodicities, and by introducing blazing.
Abstract: We numerically study complex dual-interface grating systems to enhance absorption efficiency in thin-film silicon solar cells. We combine a plasmonic grating at the back side of the solar cell with a dielectric grating at the front side of the cell. We show a proof of principle, with one-dimensional gratings, that the distinctly different nature of the gratings can provide complementary enhancement mechanisms, which we further exploit by tailoring the specific periodicities, and by introducing blazing. Having different periods at specific interfaces allows for more efficient diffraction into both plasmonic and dielectric guided modes. In addition, grating specific blazing exposes extra modes to normal incident light through symmetry breaking. Multiple optimization routes are possible depending on the choice of photonic phenomena.

TL;DR: In this article, a search for new physics is presented based on an event signature of at least three jets accompanied by large missing transverse momentum, using a data sample corresponding to an integrated luminosity of 36 inverse picobarns collected in proton--proton collisions at sqrt(s)=7 TeV with the CMS detector at the LHC.
Abstract: A search for new physics is presented based on an event signature of at least three jets accompanied by large missing transverse momentum, using a data sample corresponding to an integrated luminosity of 36 inverse picobarns collected in proton--proton collisions at sqrt(s)=7 TeV with the CMS detector at the LHC. No excess of events is observed above the expected standard model backgrounds, which are all estimated from the data. Exclusion limits are presented for the constrained minimal supersymmetric extension of the standard model. Cross section limits are also presented using simplified models with new particles decaying to an undetected particle and one or two jets.

TL;DR: Thirty-three tournament-level young Belgian chess players aged 8 to 13 were tested with the French WISC and the results suggest that a high level of general intelligence and of spatial ability are necessary to achieve a high standard of play in chess.
Abstract: Thirty-three tournament-level young Belgian chess players aged 8 to 13 were tested with the French WISC (Wechsler Intelligence Scale for Children). The mean full scale IQ = 121, verbal IQ = 109 and performance IQ = 129. The results suggest that a high level of general intelligence and of spatial ability are necessary to achieve a high standard of play in chess. The high spatial ability of these young chess players suggested by the high performance IQs may go some way towards explaining why males tend to be more numerous than females among high-standard chess players.

TL;DR: In this article, the electronic structure of PPV was studied using photoelectron spectroscopy, UPS and XPS, and it was shown that the Na-doping of a PPV results in the formation of bipolaron bands in the otherwise forbidden energy gap at saturation doping.

TL;DR: In this paper, the authors proposed a linear programming (LP) model which does not require normalization and detects the factorization rank automatically, which is more flexible, significantly more tolerant to noise, and can easily be adapted to handle outliers and other noise models.
Abstract: Nonnegative matrix factorization (NMF) has been shown recently to be tractable under the separability assumption, under which all the columns of the input data matrix belong to the convex cone generated by only a few of these columns. Bittorf, Recht, Re and Tropp ('Factoring nonnegative matrices with linear programs', NIPS 2012) proposed a linear programming (LP) model, referred to as Hottopixx, which is robust under any small perturbation of the input matrix. However, Hottopixx has two important drawbacks: (i) the input matrix has to be normalized, and (ii) the factorization rank has to be known in advance. In this paper, we generalize Hottopixx in order to resolve these two drawbacks, that is, we propose a new LP model which does not require normalization and detects the factorization rank automatically. Moreover, the new LP model is more flexible, significantly more tolerant to noise, and can easily be adapted to handle outliers and other noise models. Finally, we show on several synthetic data sets that it outperforms Hottopixx while competing favorably with two state-of-the-art methods.
