Bott-Duffin weak group inverse of matrices
The paper introduces the concept of Bott-Duffin weak group inverse (in short, BDWG-inverse) of a square matrix with respect to subspace. We study some properties, representations and characterizations of the BDWG-inverse. Finally, we use this inverse to solve some restricted line...

The Windmill Problem's Dynamic Symmetry vs. Combinatorial Invariants — E8 Intelligence Research
FINDING: The "windmill" problem (2011 IMO Q2) is the most structurally profound — it encodes a dynamic symmetry of point configurations, while the Putnam problem and 100 Prisoners Riddle reveal combinatorial invariants and cycle-structure symmetries respectively. | MATH: Windmill...

Froebel’s gifts: how the kindergarten movement changed the immigrant family
Abstract Nineteenth-century social reformers promoted the establishment of kindergartens to facilitate the integration of immigrant children in the U.S. society. Exploiting newly collected data on historical kindergarten statistics, we evaluate the impact that the roll-out of the...

A report suggestive of canine transmissible venereal tumour in a medieval hunting manual
The canine transmissible venereal tumour (CTVT) is a cancer lineage that is passaged between dogs by the transfer of living cancer cells during mating. This disease, which causes the appearance of genital tumours in male and female dogs, is found in many countries around the worl...
