Observational Constraints on Phantom Crossing DGP Gravity

We study the observational constraints on the Phantom Crossing DGP model. We demonstrate that the crossing of the phantom divide does not occur within the framework of the original Dvali-Gabadadze-Porrati (DGP) model or the DGP model developed by Dvali and Turner. By extending their model in the framework of an extra dimension scenario, we study a model that realizes crossing of the phantom divide. We investigate the cosmological constraints obtained from the recent observational data of Type Ia Supernovae, Cosmic Microwave Background anisotropies, and Baryon Acoustic Oscillations. The best fit values of the parameters with 1$\sigma$ (68%) errors for the Phantom Crossing DGP model are $\Omega_{m,0}=0.27^{+0.02}_{-0.02}$, $\beta=0.54^{+0.24}_{-0.30}$. We find that the Phantom Crossing DGP model is more compatible with the observations than the original DGP model or the DGP model developed by Dvali and Turner. Our model can realize late-time acceleration of the universe, similar to that of $\Lambda$CDM model, without dark energy due to the effect of DGP gravity. In our model, crossing of the phantom divide occurs at a redshift of $z \sim 0.2$.Comment: 17 pages, 9 figures, 1 table, Accepted for publication in International Journal of Modern Physics

Evaluation the lines of rice the highlands of aims to identify lines being sappy the result of higher than varieties Sarinah and Inpari 28 Kerinci. As many as 24 lines rice early maturity together varieties Sarinah and Inpari 28 Kerinci by contrast has been tested power results in Kayu Aro Solok West Sumatra ( 850 m above sea level). Research using randomized block design with three replications. m Fertilizer aplicated at rate of 200 kg of Urea, 100 kg SP 36 and Kcl 100 kg/ha. The 25 days old seedling after sowing were planted in 3x4 m2 size plots with plant spacing 25 x 25 cm and three seedling per hole. The research results obtained seven lines of lawland rice fields into alleged able to adapt to increased production in cumulative range 0.31-0.82 t/ha compared to varieties Sarinah, the seventh such lines is BP13990-3B-GRT-3-1-7-2, BP13990-3B-GRT-3-1-7-8, BP13990-3B-GRT-3-1-7-9, BP13990-3B-GRT-3-1-8.4, BP13990-3B-GRT-3-1-7-4, BP13990-3B-GRT-3-1-8-8 and BP14022-10B-GRT-2-3-2. Age of plant lines are more early than varieties Sarinah and Inpari 28 Kerinci. The power steadiness and power adaptation results of lines that needs to be evaluated on a different environment conditions

Superior varieties is one component of the innovative technology that is reliable and gives a real contribution to the success of an increase in the productivity of food crops in Indonesia. To that end, the discovery of new superior variety is continuously carried out absolute in order to anticipate changes in the structure of the plant organism, the situation is very dynamic, the resilience of a superior varieties of plant organism could not last long. Testing adaptation promissing lines is one of the stages approach to filter lines that are capable of adapting well and has high yield potential. In 2009 has been carried out 10 test promissing lines of rice fields on two locations in Solok Regency of West Sumatra from Agustus 2009 to Januari 2010. The experiment used a randomized complete block design, with four replication was used, plot size 4.0 m x 5.0 m Fertilizer aplicated at rate of 280 kg of Urea, 100 kg SP 36 and 100 kg KCl/ha. The results showed promissing lines BP10620F-BB4-15-BB8 and BP2842E-14-2 were 21.50% and 21,72% more than varieties IR42. Plant high posture all the promissing lines including the ideal that is with the range of 85-105 cm

The implementation of the selection that refers to the use of genetic parameter value might expect very effective help in accelerating the discovery of a superior genotypes in accordance with plant breeding program. Twelve promissing lines and check varieties of soybean were planted at KP Sitiung Dharmasraya on two seasons namely MT1 from August-November 2009 and MT2 from December to March 2010. Fertilization with a dose of 75 kg of urea was 125 kg SP36 and 75kg of KCl/ha, the plot size is 2.80 m x 4.0 m. A randomized complete block design with four replication. Variable measured were agronomic characters, yield component and yield. The results the experiment indicated that heritability of all the characters were high (50,43% - 95,98%). Only heritability of plant high at MT1 and yield both environments was medium. The value of guess heritabilitas high on productive branch character per plant and pods per plant is supported by genetic advances and coefficient of average genetic variation is quite high and high, thus both these characters can be reference selection criteria to get productive branches per plant and pods per plant

Cepstral analysis based on the Glimpse proportion measure for improving the intelligibility of HMM-based synthetic speech in noise

In this paper we introduce a new cepstral coefficient extraction method based on an intelligibility measure for speech in noise, the Glimpse Proportion measure. This new method aims to increase the intelligibility of speech in noise by modifying the clean speech, and has applications in scenarios such as public announcement and car navigation systems. We first explain how the Glimpse Proportion measure operates and further show how we approximated it to integrate it into an existing spectral envelope parameter extraction method commonly used in the HMM-based speech synthesis framework. We then demonstrate how this new method changes the modelled spectrum according to the characteristics of the noise and show results for a listening test with vocoded and HMM-based synthetic speech. The test indicates that the proposed method can significantly improve intelligibility of synthetic speech in speech shaped noise. Index Terms — cepstral coefficient extraction, objective measure for speech intelligibility, Lombard speech, HMM-based speech synthesis 1

Dynamical symmetry breaking of SU(6) GUT in 5-dimensional spacetime with orbifold S1/Z2

The symmetry breaking of 5-dimensional SU(6) GUT into 4-dimensional SU(3) x SU(3) x U(1) with orbifold S1/Z2 through Scherk-Schwarz mechanism is investigated. It is shown that the origin of Little Higgs can be generated to further break SU(3) x SU(3) x U(1) down to the electroweak scale through Higgs mechanism.Comment: 4 page

Proton decay in 5D SU(6) GUT with orbifold S^1/Z_2 breaking in Scherk-Schwarz mechanism

Proton decay within 5-dimensional SU(6) GUT with orbifold S^1/Z_2 breaking is investigated using Scherk-Schwarz mechanism. It is shown that in the model neither leptoquark like heavy gauge bosons nor violation of baryon number conservation are allowed due to the orbifold breaking parity splitting. These results prevent too short proton lifetime within the model.Comment: 6 pages, Proceeding of the Conference in Honour of Murray Gell-Mann's 80th Birthday : Quantum Mechanics, Elementary Particles, Quantum Cosmology, Complexity (2011) 544-54
