On a Geometrical Interpolation Problem

Given a finite set of points A in R and a geometrical pattern Φ we define a type of distance between A and Φ and study how to find a pattern Φ among a parametrized family of geometrical objects such that such a distance is minimum. Mathematics Subject Classification: 41A29

A Survey on Current Methods of Carpal Height Ratio Measurement and Suggestion of a New Method

Background & Aims: Two famous methods are commonly used for the measurement of carpal height ratio. Both methods are performed on anteroposterior radiogram and have some shortcomings. We are going to introduce a new method for measuring this index in lateral view of the wrist radiogram' Methods: This cross-sectional and case-control study was conducted on 100 anteroposterior and lateral radiogr...

Canals Beyond Mars: Beam Depolarization in Radio Continuum Maps of the warm ISM

Multi-frequency radio polarimetric observations of the diffuse Galactic synchrotron background enable us to study the structure of the diffuse ionized gas via rotation measure maps. However, depolarization will introduce artifacts in the resulting rotation measure, most notably in the form of narrow, elongated “depolarization canals”. We use numerical models of a non-emitting Faraday rotating m...
