Least action principle for envelope functions in abrupt heterostructures
, 2005 We apply the envelope function approach to abrupt heterostructures starting with the least action principle for the microscopic wave function. The interface is treated nonperturbatively, and our approach is applicable to mismatched heterostructure.

New Phytologist, Volume 249, Issue 3, Page 1268-1282, February 2026.Summary Exogenously applied auxins are essential for establishing cell lines in tissue cultures and maintaining their proliferation. Cell lines may develop the ability to proliferate even in media lacking auxin, they may become auxin‐habituated. This study investigated the mechanisms underlying this process.

The Martyrdom of Nadezhda Kurchenko: Soviet Hero Cults and the Spiritual Turn in Late Socialism
The Russian Review, Volume 85, Issue 1, Page 69-87, January 2026.Abstract This article argues that the spiritual turn in Soviet atheism under Brezhnev provided a meaningful solution to the problems of producing heroes when self‐sacrificing martyrs were losing their appeal. To support this claim, I examine the story of Nadezhda Kurchenko, a nineteen‐year‐old flight attendant killed by two hijackers on an Aeroflot ...
