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...

In the late 1970s the convective system that is referred to as the bow echo was identified by Fujita (1978). It was identified as a type of convective storm structure associated with intense damaging winds or downburst (Johns 1993). As more of these systems were studied, a better understanding was made on their kinematic structure and dynamical processes. Bow echoes can range in size from 15 km...

A bow-tie slot antenna with tapered connection to a 50Ω coplanar waveguide (CPW) feed line is introduced and its dimensional parameters have been studied for wideband operations in the X-band. A set of two element bow-tie slot antennas fed by one CPW is also introduced for wider bandwidth and improved gain. The configuration of one CPW feeding two elements of this antenna is simulated and it ac...

In this paper, the design and construction of a new violin interface, the Hyperbow, is discussed. The motivation driving the research of this instrument was the desire to create a violin bow capable of measuring the most intricate aspects of violin technique–the subtle elements of physical gesture that immediately and directly impact the sound of the instrument while playing. In order to provid...

In this paper, we present a procedure to predict bow pressing force in a violin from data acquired in real recordings. We focus on the calibration procedure that must be robust to the bow tension changes in long recordings and fast enough to not disturb the recording session. Because of this last limitation, the calibration method here proposed does not exhaustively cover all the possible bow c...
