This paper presents codification of multi-objective passive defense in unit commitment, aiming vulnerability reduction, feeding continuity, reliability enhancement, and increasing confronting potency. Consideration of multi-objective passive defense in the operation and planning of generation units is one of the important principles in dealing with military threats. In this work unit commitment...
Nudibranchs are marine invertebrates that use various defenses to deter predators. Peltodoris nobilis is a member of the superfamily Doridoidea and uses de novo chemical synthesis for defense. Hermissenda crassicornis Aeolidioidea nematocyst sequestration Past research explains function evolution in nudibranchs; however, it unknown whether these active or passive. The goal this was determine if...

Red-backed shrikes (Lanius collurio) behave quite differently towards two common nest predators. While the European jay (Garrulus glandarius) is commonly attacked, in the presence of the Eurasian magpie (Pica pica), shrikes stay fully passive. We tested the hypotheses that this passive response to the magpie is an alternative defense strategy. Nesting shrikes were exposed to the commonly attack...
Two hypotheses have been proposed recently that offer different views on the role of airway surface liquid (ASL) in lung defense. The "compositional" hypothesis predicts that ASL [NaCl] is kept low (<50 mM) by passive forces to permit antimicrobial factors to act as a chemical defense. The "volume" hypothesis predicts that ASL volume (height) is regulated isotonically by active ion transport to...
