This paper studies the special case of the triangular system of equations in Vytlacil and Yildiz (2007), where both dependent variables are binary but without imposing the restrictive support ...

Magnetism plays a key role in modern science and technology, but still many open questions arise from the interplay of magnetic many-body interactions. Deeper insight into complex magnetic behaviour ...

In this paper is presented a simultaneous equation model that is non-triangular, its disturbances having a non-diagonal covariance matrix, and yet is causal and recursive, and whose underlying ...

Structures that respond to rising temperature by moving in a carefully controlled manner are being developed by scientists in Malta. The material contains a frameworks of struts, which each respond ...
