The title compound, C20H15N3OS, is V-shaped. In the 4-phen-oxy-phenyl group, the two rings are inclined to one another by 74.52 (13)°. These rings are inclined to the triazole ring by 72.20 (15) and 72.30 (15)°, respectively. The phenyl ring is inclined to the triazole ring by 10.85 (12)°. In the crystal, mol-ecules are linked via N-H⋯N hydrogen bonds, forming chains propagating along [010]. Th...

Square is a multivariate quadratic encryption scheme proposed in 2009. It is a specialization of Hidden Field Equations by using only odd characteristic elds and also X as its central map. In addition, it uses embedding to reduce the number of variables in the public key. However, the system was broken at Asiacrypt 2009 using a di erential attack. At PQCrypto 2010 Clough and Ding proposed two n...

Dans une permutation, un record est maximum ou minimum, en partant de la droite gauche. Les éléments d’une permutation peuvent être classés deux types : les records (dits points extérieurs) et autres intérieurs). permutations sans point intérieur ont été étudiées sous le nom carrées. Ici, nous explorons ayant nombre fini intérieurs, dites quasi-carrées. Contrairement aux carrées, l’énumération ...

This study aims to validate the accuracy of a cervical traction therapy simulation model by comparing the intervertebral separations of six asymptomatic male adults when traction was applied to their cervical spines. The subjects were tested on two mechanical traction devices, representing the inclined and sitting positions. A total of 55 radiographic images of their cervical spines were taken ...

We investigate the motion of a liquid drop as it flows along the interface of a liquid film. Steady, two-dimensional solutions are found in the lubrication limit for a horizontal and inclined plane. The effects of the physical parameters on the interface shapes are studied. When the plane is inclined, solutions are found only for a special set of parameter values.

In the title salt, C17H19N4 (+)·PF6 (-), the two pyridine rings of the cation are inclined to one another by 15.89 (8)°, and inclined to the imidazole ring by 65.05 (10) and 64.07 (10)°. In the crystal, the cations and anions are linked via a series of C-H⋯N and C-H⋯F hydrogen bonds, forming two-dimensional networks lying parallel to (001).
