We provide a systematic method to compute tree-level scattering amplitudes with spinning external states from scalar in arbitrary spacetime dimensions. write down analytic answers for various amplitudes, including the four graviton amplitude due massive spin $J$ exchange. verify results by computing angular distributions 3 + 1 dimensions using identities involving Jacobi polynomials.

opinion mining deals with an analysis of user reviews for extracting their opinions, sentiments and demands in a specific area, which can play an important role in making major decisions in such area. in general, opinion mining extracts user reviews at three levels of document, sentence and feature. opinion mining at the feature level is taken into consideration more than the other two levels d...

When combined with the electroretinogram (ERG), the heterochromatic flicker photometry procedure allows an objective in vivo assessment of postreceptoral activity. Responses evoked at intermediate (approximately 12 Hz) and high (>30 Hz) temporal frequencies reflect the red-green cone opponent (possibly parvocellular) and the luminance (possibly magnocellular) responses, respectively. Previously...

Numerical simulations of black-hole binaries, obtained with the Lean code, are presented. The code is demonstrated to produce state-of-the-art evolutions of inspiralling and merging black holes with convergent waveforms. We further compare results from head-on collisions of Brill-Lindquist and Kerr-Schild data to study the dependency of the waveforms on the choice of initial data type. In this ...

We explore two recent methods for measuring the Modeling Transfer Function of a printing system. We investigate the dependency on the amplitude when using the sinusoidal patches of the method proposed in and show that for too small amplitudes the measurement of the MTF is not trustworthy. For the method proposed in we discuss the underlying theory and in particular the use of a significance tes...

Background: The main goal of this study is to determine the relationship between opium dependency and frequency of urolithiasis renal colics. Methods: In a cross sectional study we compared opium dependency in urolithiasis patients (case group) with non-urolithiasis patients (control group) and assessed urolithiasis related renal colics as risk factor to opium dependency prevalence. Dependency ...
