The Matilda Effect and Women's Representation in Biology

open access: yesThe Bulletin of the Ecological Society of America, EarlyView.
Abstract The undervaluing of minorities and their researcher contributions reduces when a threshold level of minority representation (between 15 and 30%) is reached in a group or community. Botany is celebrated as a discipline in which women have been able to make important contributions, especially in the past.

How Much Should a 19th-Century French Bastard Inherit [PDF]

open access: yesJournal of Difference Equations and Applications 3(1998), 385-388, 1998
Catalan's formula, for the portion of the inheritance that a legitimate child of a 19th-century deceased French gentleman should receive, is given a new proof (using Difference Operators), and generalized. Another, more computationally efficient, formula is also derived.

On the Definition of Chirality and Enantioselective Fields

open access: yesIsrael Journal of Chemistry, Volume 62, Issue 11-12, December 2022., 2022
Abstract In solid state physics, any symmetry breaking is known to be associated with emergence of an order parameter. However, the order parameter for molecular and crystal chirality, which is a consequence of parity and mirror symmetry breaking, has not been known since its discovery.
