The evolution of transformation media in spherical trigonometry in 17th- and 18th-century China, and its relation to “Western learning” [PDF]
, 2010 Problems of spherical trigonometry in 17th- and 18th-century China were often reduced to problems in plane trigonometry and then solved by means of the proportionality of corresponding sides of similar right triangles.

Area of origin analysis for expirated patterns using HemoVision. [PDF]
J Forensic SciAbstract Although bloodstain pattern analysis (BPA) can be performed on various types of patterns, there is a lack of research looking into whether the area of origin (AO) can be determined for expirated patterns. Expirated patterns are formed when blood is pushed out of an opening in the body by the force of air, in some cases forming a pattern of ...
