Maximal violation of Clauser-Horne-Shimony-Holt inequality for two qutrits

Bell-Clauser-Horne-Shimony-Holt inequality (in terms of correlation functions) of two qutrits is studied in detail by employing tritter measurements. A uniform formula for the maximum value of this inequality for tritter measurements is obtained. Based on this formula, we show that non-maximally entangled states violate the Bell-CHSH inequality more strongly than the maximally entangled one. This result is consistent with what was obtained by Ac{\'{i}}n {\it et al} [Phys. Rev. A {\bf 65}, 052325 (2002)] using the Bell-Clauser-Horne inequality (in terms of probabilities).Comment: 6 pages, 3 figure

Mutual correlation in the shock wave geometry

We probe the shock wave geometry with the mutual correlation in a spherically symmetric Reissner Nordstr\"om AdS black hole on the basis of the gauge/gravity duality. In the static background, we find that the regions living on the boundary of the AdS black holes are correlated provided the considered regions on the boundary are large enough. We also investigate the effect of the charge on the mutual correlation and find that the bigger the value of the charge is, the smaller the value of the mutual correlation will to be. As a small perturbation is added at the AdS boundary, the horizon shifts and a dynamical shock wave geometry forms after long time enough. In this dynamic background, we find that the greater the shift of the horizon is, the smaller the mutual correlation will to be. Especially for the case that the shift is large enough, the mutual correlation vanishes, which implies that the considered regions on the boundary are uncorrelated. The effect of the charge on the mutual correlation in this dynamic background is found to be the same as that in the static background.Comment: 10 page

Review on Pulling Force of Agricultural Labor and Its Effectiveness in China

This essay details a 3D simulation of a number of control methods used for maneuvering of teleoperated USAR robots. The implementation was produced in the Unity3D engine. The simulation implemented different variations on field-ofview angle, turning algorithms, and camera view perspectives. An evaluation using volunteer test operators was conducted and discussed. The sample size was too small to draw any definitive conclusions. Further testing is advised.Denna uppsats behandlar en 3D-simulering samt användartester av flera olika kontrollmetoder som används vid fjärrstyrning av obemannade räddningsrobotar. Implementationen skapades med Unity3D-plattformen. De styrmetoder som testades var olika stora synfältsvinklar på kameran, olika algoritmer för att styra robotens svängning, samt olika kameraperspektiv. Användartester med frivilliga testförare genomfördes och diskuteras. Provstorleken var för liten för att kunna dra några definitiva slutsatser. Ytterligare tester rekommenderas

3-Bromo-1-(3-chloro­pyridin-2-yl)-N-(4-eth­oxy­phen­yl)-1H-pyrazole-5-carbox­amide

In the title compound, C17H14BrClN4O2, the pyrazole ring is almost coplanar with the benzene ring [dihedral angle = 0.5 (2)°], whereas the pyrazole ring is close to perpendicular to the 3-chloro­pyridine ring [dihedral angle = 73.7 (2)°]. An intra­molecular C—H⋯O hydrogen bond occurs. The dominant inter­action in the crystal packing is an N—H⋯N hydrogen bond, which generates a chain along the c axis. Weak inter­molecular C—H⋯O and C—H⋯N contacts are also observe
