SdeaR: Stochastic data envelopment analysis with R
SoftwareXThis paper introduces SdeaR , an open-source R package for stochastic data envelopment analysis (DEA) based on chance-constrained programming. Unlike conventional DEA models, which assume deterministic inputs and outputs, SdeaR explicitly incorporates ...

Integrating slacks-based measure of efficiency and super-efficiency in data envelopment analysis
Omega, 2019 In this paper, we develop an integrated model for slacks-based measure (SBM) simultaneously of both the efficiency and the super-efficiency for decision-making units (DMUs) in data envelopment analysis (DEA). Unlike the traditional solution approaches in

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite
Advanced Functional Materials, EarlyView.The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.
