Some short-period exoplanets (“hot Jupiters”) are observed by their transits to have anomalously large radii. It has been suggested that these planets are in a resonance involving persistent misalignment and synchronous precession of their spin and orbital angular momenta—a Cassini state—and that the attendant tidal heating inflates the planet. We argue against this. Using explicit tidal integr...

BACKGROUND Bohler's angle (BA) is the most commonly utilized radiographic measurement in the study of calcaneus fractures and has been shown to be prognostic in nature. Therefore, it is critical that the measurement of BA be accurate as both therapeutic and prognostic information relies on it. Oblique lateral radiographs can be a cause of error in BA measurements. However, measurement error and...

Lateral obliquity of the forearm from the arm when the forearm is supinated and extended is called carrying angle. In this study carrying angle was measured using radiographs of adult individuals and morphometry was done on dry bones taking part in formation of human elbow (on lower end of humerus-trochlear angle and inclination angle of olecranon fossa, on upper end of ulna-olecranon-coronoid ...

We explore the impact of obliquity variations on planetary habitability in hypothetical systems with high mutual inclination. We show that large-amplitude, high-frequency obliquity oscillations on Earth-like exoplanets can suppress the ice-albedo feedback, increasing the outer edge of the habitable zone. We restricted our exploration to hypothetical systems consisting of a solar-mass star, an E...

Studies on human perception have identified pelvis and torso motion as key discriminators between male and female gaits. However, while most observers would advocate that men and women walk differently, consistent findings and explanations of sex differences in gait kinematics across modern empirical studies are rare. In the present study we evaluated sex differences in whole body gait kinemati...

Kirchhoff diffraction formulations that use the wave front and the aperture plane for the surfaces of integration were compared. The full Kirchhoff obliquity factor terms distinguishing these two formulations are presented for spherical waves and for Gaussian laser beams. When they are used, identical results are obtained for the two formulations in both the spherical-wave and the Gaussian lase...

STUDY DESIGN This retrospective study evaluates two groups of patients with scoliosis and Duchenne muscular dystrophy, treated with two different surgical stabilization methods. OBJECTIVE To determine whether fixation to the sacropelvis is always necessary for adequate stabilization of scoliosis in Duchenne muscular dystrophy. SUMMARY OF BACKGROUND DATA Pelvic fixation is generally recommen...

I will attempt to demonstrate that the ‘sacred triangles based on solar angle’ hypothesis cannot be regarded as a serious scientific proposition because it seems uncorroborated by any solid evidence. It is more an example of circular reasoning, which entails supporting idea ancient Slavs knew about obliquity ecliptic pointing purported existence triangles’, while also proving these triangles’ d...

Variations in diurnal tidal stress due to Europa’s eccentric orbit have been considered as the driver of strike-slip motion along pre-existing faults, but obliquity and physical libration have not been taken into account. The first objective of this work is to examine the effects of obliquity on the predicted global pattern of fault slip directions based on a tidal-tectonic formation model. Our...
