Abstract. Spring embedders are conceptually simple and produce straight-line drawings with an undeniable aesthetic appeal, which explains their prevalence when it comes to automated graph drawing. However, when drawing planar graphs, spring embedders often produce non-plane drawings, as edge crossings do not factor into the objective function being minimized. On the other hand, there are fairly...

The effects of gaze eccentricity on the steering of an automobile were studied. Drivers performed an attention task while attempting to drive down the middle of a straight road in a simulation. Steering was biased in the direction of fixation, and deviation from the center of the road was proportional to the gaze direction until saturation at approximately 15 degrees gaze-angle from straight ah...

The aim of this study was to investigate the relationship between growth opportunities, risks, and relative changes in the Company's cash assets. This study is a literature study and analysis was based on an analysis of panel data. In this study, a financial data of 112 companies listed in Tehran Stock Exchange during the period 2009 to 2014 have been reviewed. The results in relation to the fi...

34 Understanding how animals control locomotion in different behaviors requires understanding 35 both the kinematics of leg movements and the neural activity underlying these movements. 36 Stick insect leg kinematics differ in forward and backward walking. Describing leg muscle 37 activity in these behaviors is a first step towards understanding the neuronal basis for these 38 differences. 39 4...

We investigate a class of generalized Schrödinger operators in L 2 (R 3) with a singular interaction supported by a smooth curve Γ. We find a strong-coupling asymptotic expansion of the discrete spectrum in case when Γ is a loop or an infinite bent curve which is asymptotically straight. It is given in terms of an auxiliary one-dimensional Schrödinger operator with a potential determined by the...

BACKGROUND Both maxillary protraction and rapid expansion are recommended for patients with cleft palate and alveolus. The aim of the study is to establish a three-dimensional finite element model of the craniomaxillary complex with unilateral cleft palate and alveolus to simulate maxillary protraction with and without rapid maxillary expansion. The study also investigates the deformation of th...

Strong Kronecker multiplication of two matrices is useful for constructing new orthogonal matrices from those known. These results are particularly important as they allow small matrices to be combined to form larger matrices, but of smaller order than the straight-forward Kronecker product would permit.

Benign gastrojejunocolic fistula is mostly due to Bilroth II operations. It typically presents with a triad of feculent vomiting, weight loss and chronic diarrhoea but sometimes the diagnosis is not straight forward. We discuss a case that presented and was investigated as intestinal obstruction however diagnosed with gastrojejunocolic fistula during surgery.

An efficient and straight forward procedure for the syntheses of bicyclic isoxazole/isoxazoline derivatives from the corresponding dimethyl-2-(2-nitro-1-aryl/alkyl)-2-(prop-2-yn-1yl)malonates or dimethyl 2-allyl-2-(2-nitro-1-aryl/alkyl ethyl)malonate is described. High yields and simple operations are important features of this methodology.

The dynamics of a rotating elastic filament is investigated using Stokesian simulations. The filament, straight and tilted with respect to its rotation axis for small driving torques, undergoes at a critical torque a strongly discontinuous shape bifurcation to a helical state. It induces a substantial forward propulsion whatever the sense of rotation: a nanomechanical force-rectification device...
