Which acceptable agreements are equilibria?
This paper proposes a one shot normal form game of agreement formation. It introduces a new notion of strategy, which is, for each player, to say which of the possible agreements are acceptable. Therefore, the strategy is a vector of choices. For a given strategy profile, different sizes are then acceptable and it is assumed that the largest agreement is achieved. I propose a concept of strong ...
متن کاملDosimetric Evaluation of Linac Photon Small Fields using MAGIC Polymer Gels
Introduction: In radiotherapy, methods of treatment planning are becoming increasingly more complicated. This requires verification of the doses delivered to increasingly smaller and more precise regions. Radiotherapy techniques are continuously employing smaller and smaller field sizes to deliver tighter radiation doses with higher therapeutic ratios, generating interest among researchers to p...
متن کاملAdverse effects of acupuncture. Which are clinically significant?
OBJECTIVE To review potentially serious adverse events associated with acupuncture. QUALITY OF EVIDENCE Studies in the medical literature primarily provide level II evidence from retrospective reviews, case reports, and prospective surveys of practitioners. MAIN MESSAGE Both the general public and physicians are becoming more interested in the ancient Chinese medical practice of acupuncture...
متن کاملWhich Small Reaction Networks Are Multistationary?
Reaction networks taken with mass-action kinetics arise in many settings, such as epidemiology, population biology, and systems of chemical reactions. Bistable reaction networks are posited to underlie biochemical switches, which motivates the following question: Which reaction networks have the capacity for multiple steady states? Mathematically, this asks, from among certain parametrized fami...
متن کاملWhich electric fields are realizable in conducting materials?
In this paper we study the realizability of a given smooth periodic gradient field ∇u defined in R, in the sense of finding when one can obtain a matrix conductivity σ such that σ∇u is a divergence free current field. The construction is shown to be always possible locally in R provided that ∇u is non-vanishing. This condition is also necessary in dimension two but not in dimension three. In fa...
