We determine the ground-state phase diagram of the one-dimensional half-filled Hubbard model with on-site (nearest-neighbor) repulsive interaction U (V) and nearest-neighbor hopping t using the density-matrix renormalization group technique. Based on the results of the excitation gaps, Luttinger-liquid exponents, and bond-order-wave (BOW) order parameter, we confirm that the BOW phase appears i...

A review text is normally represented as a bag-of-words (BOW) in sentiment classification. Such a simplified BOW model has fundamental deficiencies in modeling some complex linguistic phenomena such as negation. In this work, we propose a dual-view co-training algorithm based on dual-view BOW representation for semisupervised sentiment classification. In dual-view BOW, we automatically construc...

Lossless bowed strings have usually been thought to possess a motion discovered by Helmholtz in 1863. However, it was shown [Acustica 44, 194-206 {1980)] by the author that a more complicated standing wave motion, the $ motion, exists on such strings provided both the bowing distance and bowing force are above certain minimum values. This paper explores S-motion harmonics which give arise to wa...

This paper presents the results of two recent pilot experiments conducted to investigate the performance of a realtime physical violin model using bowing parameters generated by a real player. In each of these two experiments, the calibrated bowing parameters of bow force, bow speed, and bow position (bow-bridge distance) are mapped to the calibrated inputs of the physical model in order to exa...

Exploring the structural topology of genome-based large-scale metabolic network is essential for investigating possible relations between structure and functionality. Visualization would be helpful for obtaining immediate information about structural organization. In this work, metabolic networks of 75 organisms were investigated from a topological point of view. A spread bow-tie model was prop...

Beamed γ-ray burst (GRB) sources produce a bow shock in their gaseous environment. The emitted flux from this bow shock may dominate over the direct emission from the jet for lines of sight which are outside the angular radius of the jet emission, Θb. The event rate for these lines of sight is increased by a factor of ∼ 260(Θb/5◦)−2. For typical GRB parameters, we find that the bow shock emissi...

The bow effect is ubiquitous in standard absolute identification experiments; stimuli at the center of the stimulus-set range elicit slower and less accurate responses than do others. This effect has motivated various theoretical accounts of performance, often involving the idea that end-of-range stimuli have privileged roles. Two other phenomena (practice effects and improved performance for f...

Flows around a wedge-shaped bow are simulated with the aim of investigating the wave breaking mechanism and small scale features of ship bow waves. The wedge geometry used in the experimental study of Waniewski et al. (2002) is chosen with the flow conditions at Re = 1.64×10 5 and Fr = 2.93. The bow wave structure, wave breaking process and air entrainment are studied. The predicted overall bow...

The purpose of our study was to investigate the radiographic characteristics of atypical femoral shaft fractures (AFSFs) in females with a particular focus on femoral bow and cortical thickness. We performed a fracture location-, age-, gender-, and ethnicity-matched case-control study. Forty-two AFSFs in 29 patients and 22 typical osteoporotic femoral shaft fractures in 22 patients were enrolle...
