Disputed lands
In this paper we consider the classical problem of dividing a land among many agents so that everybody is satisfied with the parcel she receives. In the literature, it is usually assumed that all the agents are endowed with cardinally comparable, additive, and monotone utility functions. In many economic and political situations violations of these assumptions may arise. We show how a family of...
متن کاملComparison of Antimicrobial Properties and Toxicity of Natural S3 Peptide with Horseshoe Crab Amoebocyte Origin and its Mutants
Introduction: Antimicrobial peptides (AMPs) are compounds with antimicrobial properties that are studied widely due to the development of resistance of pathogenic bacteria to antibiotics. In the present study, the toxicity and antimicrobial effects of two natural monomeric peptides (S3 and S∆3) were compared with S3-S∆3 hybrids and S3 tetramers. Material & Methods: Protein hybrids (S∆3S3-2mer-G...

متن کاملOrigin of adaptive mutants: a quantum measurement?
This is a supplement to the paper arXiv:q-bio/0701050, containing the text of correspondence sent to Nature in 1990. Origin of adaptive mutants: a quantum measurement? Sir,-Several recent works described non-random induction of adaptive mutations by environmental stimuli 1-3.

متن کاملFair Allocation of Disputed Properties
We model problems of allocating disputed properties as generalized exchange economies in which agents have preferences and claims over multiple goods, and the social endowment of each good may not be sufficient to satisfy all individual claims. In this context, we investigate procedural and end-state principles of fairness, their implications and relations. To do so, we explore “procedural” all...
