Abstract:

In the QCD factorization (QCDF) approach we study the direct CP violation inB-0→ρ0(ω)ρ0(ω)→π+π-π+π-via theρ-ωmixing mechanism. We find that the CP violation can be enhanced by doubleρ-ωmixing when the masses of theπ+π-pairs are in the vicinity of theωresonance, and the maximum CP violation can reach 28%. We also compare the results from the naive factorization and the QCD factorization.

Abstract:

Removing the noise from an image is vitally important in many real-world computer vision applications. One of the most effective method is block matching collaborative filtering, which employs low-rank approximation to the group of similar patches gathered by searching from the noisy image. However, the main drawback of this method is that the standard deviation of noises within the image is assumed to be known in advance, which is impossible for many real applications. In this paper, we propose a non-local filtering method by using the low-rank tensor decomposition method. For tensor decompos

Abstract:

Facial Expression recognition based on Non-negative Matrix Factorization (NMF) requires the object images should be vectorized. The vectorization leads to information loss, since local structure of the images is lost. Moreover, NMF can not guarantee the uniqueness of the decomposition. In order to remedy these limitations, the facial expression image was considered as a high-order tensor, and an Orthogonal Non-negative CP Factorization algorithm (ONNCP) was proposed. With the orthogonal constrain, the low-dimensional presentations of samples were non-negative in ONNCP. The convergence characte

Abstract:

Existing tensor factorization methods assume that the input tensor follows some specific distribution (i.e. Poisson, Bernoulli, and Gaussian), and solve the factorization by minimizing some empirical loss functions defined based on the corresponding distribution. However, it suffers from several drawbacks: 1) In reality, the underlying distributions are complicated and unknown, making it infeasible to be approximated by a simple distribution. 2) The correlation across dimensions of the input tensor is not well utilized, leading to sub-optimal performance.

Abstract:

We study the direct CP violation effect in the decay mode B+→ϕK+. This decay mode is dominated by the loop induced [Formula: see text] penguin diagram with a tiny contribution from the annihilation diagram. Therefore, the standard model expectation of direct CP violation is negligibly small. Using QCD factorization approach we find the CP asymmetry in the standard model to be at percent level. We consider then two scenarios beyond the standard model, the model with an extra vector-like down quark (VLDQ) and the R-parity violating supersymmetric model (RPV) and show that the direct CP violating

Abstract:

We describe here a method for detecting physics beyond the standard model via CP violation in B→ρπ decays. Using a Dalitz-plot analysis to obtain α, along with an analytical extraction of the various tree (T) and penguin (P) amplitudes, we obtain a criterion for the absence of new physics (NP). This criterion involves the comparison of the measured |P/T| ratio with its value as predicted by QCD factorization. We show that the detection of NP via this method has a good efficiency when compared with the corresponding technique using B→ππ decays.

Abstract:

We propose a method to determine the weak CP violating angle γ by analyzing the charmless nonleptonic B→(η, η′)K decay within the QCD factorization framework. We obtain constraints in the γ–θ (the octet-singlet mixing angle in η-η′ sector) contour plane by using the world average data of direct CP-asymmetry Acp(B→(η, η′)K) and the branching ratio BR (B+→(η, η′)K+). For Acp(B→η(η′)K) = -0.33±0.12(0.031±0.021), we find that γ lies in between 60°(20°) and 160°(160°) for θ = -21.3° for μ = mb/2, whereas for μ = mband the same θ, it lies in between 75°(20°) and 150°(160°).

We investigate the direct CP violation for the decay process of B-s→P(V)π0 (P,V refer to the pseudoscalar meson and vector meson, resp.) via isospin symmetry breaking effects from the π0-η-η′ mixing mechanism in PQCD factorization approach. Isospin symmetry breaking arises from the electroweak interaction and the u-d quark mass difference by the strong interaction, which are known to be tiny. However, we find that isospin symmetry breaking at the leading order shifts the CP violation due to the new strong phases.

In K→ππ decays there is the famous ΔI = 1/2 rule with RK ≈ 1/22, whereas in B(D) → ππ decays the ratios RD,B are of order one and therefore there is no such a rule. In this work we study decay amplitudes in B(D)→ππ using QCD factorization calculations paying particular attention to discrepancies between data and theoretical estimates. Since isospin does not play a special role in factorization calculations, no ΔI

Abstract:

User influence is a very important factor for microblog user recommendation in mobile social network. However, most existing user influence analysis works ignore user’s temporal features and fail to filter the marketing users with low influence, which limits the performance of recommendation methods. In this paper, a Tensor Factorization based User Cluster (TFUC) model is proposed. We firstly identify latent influential users by neural network clustering. Then, we construct a features tensor according to latent influential user’s opinion, activity, and network centrality information. Furthermo

Abstract:

The charmless bottom meson decays are systematically investigated based on an approximate six-quark operator effective Hamiltonian from perturbative QCD. It is shown that within this framework the naive QCD factorization method provides a simple way to evaluate the hadronic matrix elements of two-body mesonic decays. The singularities caused by on mass-shell quark propagator and gluon exchanging interaction are appropriately treated. Such a simple framework allows us to make theoretical predictions for the decay amplitudes with reasonable input parameters. The resulting theoretical predictions

In this paper, we studied systematically the semileptonic decays B s ⟶ ϕ l + l − with l − = e − , μ − , τ − by using the perturbative QCD (PQCD) and the “PQCD+Lattice” factorization approach, respectively. We first evaluated all relevant form factors F i q 2 in the low- q 2 region using the PQCD approach, and we also took the available lattice QCD results at the high- q 2 region as additional input to improve the extrapolation of F i q 2 from the low- q 2 region to the endpoint q max 2 . We then calculated the branching ratios and many other physical observables A FB l , F L ϕ , S 3 , 4 , 7 ,

During BW, children with CP showed a significant increase of gait asymmetry in foot trajectory characteristics and limb intersegmental coordination. Furthe

Abstract:

Charmless 3-body decays of B mesons are studied using a simple model based on the framework of the factorization approach. We have identified a large source of the nonresonant signal in the matrix elements of scalar densities, e.g. [Formula: see text]. This explains the dominance of the nonresonant background in B → KKK decays, the sizable nonresonant fraction of order (35 ~ 40)% in K−π+π− and [Formula: see text] modes and the smallness of nonresonant rates in B → πππ decays. We have computed the resonant and nonresonant contributions to charmless 3-body decays and determined the rates for the

With the rapid expansion of the railway represented by high-speed rail (HSR) in China, competition between railway and aviation will become increasingly common on a large scale. Beijing, Shanghai, and Guangzhou are the busiest cities and the hubs of railway and aviation transportation in China. Obtaining their supply configuration patterns can help identify defects in planning. To achieve that, supply level is proposed, which is a weighted supply traffic volume that takes population and distance factors into account. Then supply configuration can be expressed as the distribution of supply leve

Abstract:

Abstract Adamantinomatous Craniopharyngioma (ACP) is a rare pituitary tumor of the sellar region, with a bimodal presentation pattern in children and middle-aged adults. ACPs are primarily driven by a mutation in CTNNB1 that prevents beta-catenin from degrading properly, resulting in accumulation in the nuclei of epithelial whorl-like structures sometimes referred to as cluster cells. Clinical management is challenging due to the location of the tumor, such that complete surgical resection is often not possible so radiation therapy, which can lead to high morbidity, is also used.

Abstract:

In this paper we examine T-violating triple-product correlations (TP's) in B→V1V2 decays. TP's are excellent probes of physics beyond the standard model (SM) for two reasons: (i) within the SM, most TP's are expected to be tiny, and (ii) unlike direct CP asymmetries, TP's are not suppressed by the small strong phases which are expected in B decays. TP's are obtained via the angular analysis of B→V1V2. In a general analysis based on factorization, we demonstrate that the most promising decays for measuring TP's in the SM involve excited final-state vector mesons, and we provide estimates of suc

Vaš asked whether there exists a clean ring with involution * that is not *-clean. In a recent paper, Gao, Chen and the first author investigated when a group ring RG with classical involution * is *-clean and obtained necessary and sufficient conditions for RG to be *-clean, where R is a commutative local ring and G is one of C3, C4, S3 and Q8. As a consequence, the authors provided many examples of group rings which are clean, but not *-clean. In this pap

Abstract:

Solid-state nuclear magnetic resonance (ssNMR) spectroscopy provides information on native structures and the dynamics for predicting and designing the physical properties of multi-component solid materials. However, such an analysis is difficult because of the broad and overlapping spectra of these materials. Therefore, signal deconvolution and prediction are great challenges for their ssNMR analysis. We examined signal deconvolution methods using a short-time Fourier transform (STFT) and a non-negative tensor/matrix factorization (NTF, NMF), and methods for predicting NMR signals and physica

Abstract:

The heterogeneous information networks are omnipresent in real-world applications, which consist of multiple types of objects with various rich semantic meaningful links among them. Community discovery is an effective method to extract the hidden structures in networks. Usually, heterogeneous information networks are time-evolving, whose objects and links are dynamic and varying gradually. In such time-evolving heterogeneous information networks, community discovery is a challenging topic and quite more difficult than that in traditional static homogeneous information networks.
