One Step Forward, Two Steps Back: Managing Uncertainties in Outcomes, Deliverables, and Means in Behavioral Intervention Development Projects

open access: yesJournal of Operations Management, Volume 72, Issue 1, Page 81-107, January 2026.
ABSTRACT We take an extended perspective on project success that includes post‐project outcomes as well as at‐end and during‐project success. To manage projects accordingly, we conceptualize three corresponding orders of uncertainty (outcomes, deliverables, and means uncertainties).

Reversal Asymmetry of Reciprocal Metasurface Enables Ultra‐Compact Varifocal Reflective Lens

open access: yesLaser &Photonics Reviews, Volume 20, Issue 1, 8 January 2026.
The possibility of breaking the reversal symmetry of a lens without violating reciprocity is demonstrated. The freedom provided is utilized to realize an ultra‐compact reflective varifocal lens‐doublet based on a flat metasurface lens and a piezoelectric actuated micromirror.

Mixed‐Integer Linear Programming Approaches for Nested p$$ p $$‐Center Problems With Absolute and Relative Regret Objectives

open access: yesNetworks, Volume 87, Issue 1, Page 62-82, January 2026.
ABSTRACT We introduce the nested p$$ p $$‐center problem, a multi‐period variant of the well‐known p$$ p $$‐center problem. Using the nesting concept allows us to obtain solutions consistent over the considered time horizon, that is, facilities that are opened in a given time period stay open for subsequent periods.
